Answer: 82.5 - x = R sorry if I am wrong
Step-by-step explanation:
1. We know all the angles in a triangle add up to 180 degrees.
180 = x + x + 15 + R
2. Combine like terms
180 = 2x + 15 + R
3. Subtract 15 from both sides
165 = 2x + R
4. Divide both sides by 2
82.5 = x + R
5. Subtract x from both sides
82.5 - x = R

If the diameter is d = 8, then we divide that in half to get the radius of r = 4.
If the radius is r = 9, then we double it to get the diameter of d = 18
The formulas are:
radius = diameter/2diameter = 2*radiusI'll let you determine the others.
Answer:
Step-by-step explanation:
Diameter is twice the radius. d = 2*r
Radius is half the diameter r = d÷2
1) d = 8
r = 8÷ 2
r = 4
2) r = 9
d = 2*r
= 2*9
d = 18
3) r = 24
d = 24*2 =48
4) d = 36
r = 36 ÷2 = 18
5) d = 52
r = 52÷2 = 26
Lisa is using four pieces of ribbon to
make a headband. The lengths of the
ribbon pieces are 1.5 feet, 1 foot, 1.512
feet, and 1.54 feet. Write the ribbon
lengths in order from shortest to longest.
Answers
The ribbon lengths in order from shortest to longest are-
1 foot, 1.5 feet, 1.512 feet, 1.54 feet.
What is defined as the ascending order?Ascending order refers to the arrangement of numbers in increasing order, from smallest to largest.
Putting the numbers in ascending order:
Count how many digits are in each number. The number with the fewest digits is just the smallest. First, write it. Continue doing so until all of the numbers remaining for comparing have the same amount of digits.When comparing numbers with the same number of digits, begin by comparing the figures from the leftmost digit. Use the smallest digit to write the number.If the digits on the left are the same, move to the digits on the right and compare them. Enter the number with the smaller digit first.Continue to do with the leftover numbers until we have arranged all of them.Now as per the given number in question;
The lengths of the ribbon pieces are 1.5 feet, 1 foot, 1.512 feet, and 1.54 feet.
Arrange the smallest first, after that the second smallest and so on.
1 foot, 1.5 feet, 1.512 feet, 1.54 feet.
In this 1 foot is the smallest and 1.54 feet is the largest number.
We can write the given ascending order with less than sign also;
1 foot < 1.5 feet < 1.512 feet < 1.54 feet.

Members of the homeowners' association (HOA) want to know whether more than 45% of homeowners from a local residential community supports a 2% annual increase in HOA fees for five years to fund the resurfacing of the community swimming pool. The HOA surveys a random sample of 50 homeowners and use the results to test the hypotheses H0: p = 0.45 and Ha: p > 0.45, where p is the proportion of all homeowners who support a 2% annual increase in HOA fees for five years to fund the pool resurfacing. In the context of this study, how could a Type I error occur?
The HOA finds evidence that more than 45% of homeowners do not support the fee increase, when there isn't convincing evidence that more than 45% supports the increase.

A Type I error would occur if the HOA falsely rejects the null hypothesis that only 45% of homeowners support the fee increase when in reality more than 45% supports the increase.
A Type I error occurs when a null hypothesis is rejected when it is actually true. In this case, the null hypothesis is that only 45% of homeowners support the fee increase. To test this hypothesis, the HOA surveys a sample of 50 homeowners and uses the results to test the hypotheses H0: p = 0.45 and Ha: p > 0.45. If the HOA finds evidence that more than 45% of homeowners support the fee increase, when in reality only 45% or less of the homeowners support the fee increase, then a Type I error has occurred. On the other hand, if the HOA does not find evidence that more than 45% of homeowners support the fee increase, when in reality more than 45% of the homeowners do support the increase, then a Type I error has also occurred. In both cases, the HOA has incorrectly rejected the null hypothesis and a Type I error has occurred.

What is the surface area of the rectangle pyramid below 13 13 13
Answers
Answer:
Step-by-step explanation:
Assuming that the given dimensions of 13, 13, 13 refer to the base of the rectangular pyramid, we can calculate the surface area of the pyramid as follows:
First, we need to calculate the area of the rectangular base, which is simply length x width:
Area of rectangular base = 13 x 13 = 169 square units
Next, we need to calculate the area of each triangular face of the pyramid. Since the rectangular base has two sets of parallel sides, there are two types of triangular faces: the isosceles triangles on the sides and the right triangles on the front and back.
To calculate the area of the isosceles triangles, we need to first find the length of the slant height, which can be found using the Pythagorean theorem:
a² + b² = c²
where a and b are the base and height of the triangle (both equal to 13 in this case), and c is the slant height.
13² + 13² = c²
338 = c²
c ≈ 18.38
Now that we have the slant height, we can calculate the area of each isosceles triangle using the formula:
Area of isosceles triangle = (1/2) x base x height
Area of isosceles triangle = (1/2) x 13 x 18.38
Area of isosceles triangle ≈ 119.14 square units
To calculate the area of each right triangle, we need to use the same slant height of 18.38, along with the height of the pyramid, which is also 13. Then we can use the formula:
Area of right triangle = (1/2) x base x height
Area of right triangle = (1/2) x 13 x 18.38
Area of right triangle ≈ 119.14 square units
Since there are two of each type of triangular face, the total surface area of the pyramid is:
Surface area = area of rectangular base + 2 x area of isosceles triangle + 2 x area of right triangle
Surface area = 169 + 2 x 119.14 + 2 x 119.14
Surface area = 546.28 square units
Therefore, the surface area of the rectangular pyramid with base dimensions of 13 x 13 and height of 13 is approximately 546.28 square units.

Property of a rhombus:
In a rhombus, the diagonals are perpendicular.
The sum of the measures of the angles of a triangle is 180 deg.
Since the diagonals are perpendicular, the angles formed by the intersection of the diagonals are right angles and measure 90 deg.
m<ABD + m<CAB + 90 = 180
50 + m<CAB + 90 = 180
m<CAB + 140 = 180
(i) m<CAB = 40
The diagonals of a rhombus divide the rhombus into 4 congruent triangles.
Call the point of intersection of the diagonals E.
Triangles CEB and AEB are congruent.
m<BCA = m<DCA = 40
m<BCD = m<BCA + m<DCA = 40 + 40
(ii) m<BCD = 80
m<CDB = m<ADB = 50
m<ADC = m<CDB + m<ADB = 50 + 50
(iii) m<ADC = 100
10.
There are two angles labeled z. One is near point E and one is near point O. One of them probably is x.
Two angles measure 60 and 80. Add them to get 140.
z (near point O) and the 140 deg angle are a linear pair. their measures add to 180 deg.
z + 140 = 180
z = 40 (This is the z near point O.)
z (near point O) and 60 deg add to an interior angle of the parallelogram.
z + 60 = 40 + 60 = 100
The interior angle at vertex O measures 100 deg.
Adjacent interior angles of a parallelogram are supplementary.
100 + y = 180
y = 80
The two angles labeled z are alternate interior angles. Since the sides of a parallelogram are parallel, the two angles labeled z are congruent and measure 40 deg.
z = 40 (This is angle z near point E)

Answer:
a) 31.62 km/hb) 18.4° NE======================
GivenThe speed of the ship = 30 km/h,The speed of the current = 10 km/hA) Actual velocity is found as the sum of two vectors representing the two velocities.
Since the directions are at 90° (N and E), we will use Pythagorean to find the actual velocity.

The correct options regarding the statistical measures in this problem are given as follows:
3. The IQR remains a 2.
7. Mean 84º.
What are the quartiles and the IQR of a data-set?To find the quartiles, we need to consider the median, which is the middle value of a data-set, hence:
The first quartile is the median of the first half of the data-set.The third quartile is the median of the first half of the data-set.The interquartile range(IQR) is given by the difference of the two quartiles explained above.For question 3, adding the shoe size of 8, the ordered data-set is given by:
5, 5.5, 6, 6.5, 6.5, 7, 7.5, 8, 8, 8, 8.5.
Hence:
The first half is 5, 5.5, 6, 6.5, 6.5, meaning that Q1 = 6.The second half is 7.5, 8, 8, 8, 8.5, meaning that Q3 = 8.Hence the IQR is given by:
IQR = 8 - 6 = 2.
Thus the correct option is:
The IQR remains a 2.
For question 7, the second lowest value would remain the second highest value. The only measure that considers all the values to be calculated is the mean, hence the correct option is:
Mean 84º.

Cost for each pound of jelly beans:
Cost for each pound of almonds:
Answers
Answer:
Cost for each pound of jelly beans: $2.75
Cost for each pound of almonds: $3.75
Step-by-step explanation:
Let J be the cost of one pound of jelly beans.
Let A be the cost of one pound of almonds.
Using the given information, we can create a system of equations.
Given 3 pounds of jelly beans and 5 pounds of almonds cost $27:
\(\implies 3J + 5A = 27\)
Given 9 pounds of jelly beans and 7 pounds of almonds cost $51:
\(\implies 9J + 7A = 51\)
Therefore, the system of equations is:
\(\begin{cases}3J+5A=27\\9J+7A=51\end{cases}\)
To solve the system of equations, multiply the first equation by 3 to create a third equation:
\(3J \cdot 3+5A \cdot 3=27 \cdot 3\)
\(9J+15A=81\)
Subtract the second equation from the third equation to eliminate the J term.
\(\begin{array}{crcrcl}&9J & + & 15A & = & 81\\\vphantom{\dfrac12}- & (9J & + & 7A & = & 51)\\\cline{2-6}\vphantom{\dfrac12} &&&8A&=&30\end{array}\)
Solve the equation for A by dividing both sides by 8:
\(\dfrac{8A}{8}=\dfrac{30}{8}\)
\(A=3.75\)
Therefore, the cost of one pound of almonds is $3.75.
Now that we know the cost of one pound of almonds, we can substitute this value into one of the original equations to solve for J.
Using the first equation:
\(3J+5(3.75)=27\)
\(3J+18.75=27\)
\(3J+18.75-18/75=27-18.75\)
\(3J=8.25\)
\(\dfrac{3J}{3}=\dfrac{8.25}{3}\)
\(J=2.75\)
Therefore, the cost of one pound of jelly beans is $2.75.
