∠A and ∠B are supplementary angles. If m∠A = (3x+1)∘ and m∠B = (x-9)∘, then find the measure of ∠B.
Answer:
X= 45
Step-by-step explanation:
So you do
3x+1+x-9=180
Because supplementary angles are 180°
Then
3x+x = 4x
1 - 9 = -10
4x-10=180
4x-10+(10)=180+(10)
4x=190
x=45

1204 students are asked whether they like pizza.
The students responded 'yes', 'no' and 'undecided' in the ratio of 59 : 6 : 21Find how many students answered 'yes'.
Answer:
Step-by-step explanation:
59 would be yes as it was the first option.
Can you please help find z?
Answer:
the angle for z° is 96°
Step-by-step explanation:
Since we already know 2 of the angles and that y=18° because both of the lines opposed to y are straight, so subtract all of what we know: 360-(64+18+18)=260°. x also has straight lines with the 64°, so subtract another 64°, then the equation will be 360°-(64+64+18+18), so z should equal 196, but there are 2 z angles, so divide it by 2 and the answer should be z°=96°

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
If xx and y vary directly and y is 21 when x is 7, find y when x is 5
Answer:
y = 15
Step-by-step explanation:
We need to solve for k
y = x
21 = 7k Divide both sides by 7 to solve for k
3 = k
y = xk
y = 5(3)
y = 15
Answer: y = 15

For some number, t, the first 3 terms of an
arithmetic sequence are
t + 2, 3t, 4t + 1
Which of the following is the numerical value of the 4th
term.
Answer:
a₄ = 17
Step-by-step explanation:
The difference d between consecutive terms of an arithmetic sequence are constant, that is
a₂ - a₁ = a₃ - a₂, substituting values
3t - t - 2 = 4t + 1 - 3t
2t - 2 = t + 1 ( subtract t from both sides )
t - 2 = 1 ( add 2 to both sides )
t = 3
Thus
a₁ = t + 2 = 3 + 2 = 5
a₂ = 3t = 3(3) = 9
a₃ = 4t + 1 = 4(3) + 1 = 12 + 1 = 13
The first 3 terms of the sequence are
5, 9, 13 with
d = 9 - 5 = 13 - 9 = 4 , thus
a₄ = 13 + 4 = 17
The verticals of a triangle are (2,5) (1,2) (3,1) to see once reflect the triangle in the x-axis and then rotate the triangle 90 degrees counterclockwise about the origin. what are the coordinates of the image.
Answer:
(5,2) (2,1) (1,3)
Step-by-step explanation:
First, reflect the image over the x-axis. This affects the y of each point to become negative, and moves the triangle from quadrant I to quadrant IV. This changes the points to be (2,-5) (1,-2) (3,-1).
Next, when rotating the triangle counterclockwise about the origin, the easiest way to describe what this does to the points is that it switches the numbers for x and y, and makes all of them positive. This is because the rotation ends up moving the coordinates back into quadrant I, so they're positive. However, the rotation does switch up the points a bit. So now, the points are (5,2) (2,1) (1,3).
Answer: are (5,2) (2,1) (1,3).

Answer:
60 months

Step-by-step explanation:
\(\boxed{\begin{minipage}{6.5cm}\underline{Simple Interest Formula}\\\\$ A = P(1 + rt)$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}\)
Given:
A = $5,000P = $4,000r = 5% = 0.05Substitute the given values into the formula and solve for t:
\(\implies 5000=4000(1+0.05t)\)
\(\implies \dfrac{5000}{4000}=1+0.05t\)
\(\implies1.25=1+0.05t\)
\(\implies 0.05t=1.25-1\)
\(\implies 0.05t=0.25\)
\(\implies t=\dfrac{0.25}{0.05}\)
\(\implies t=5\; \rm years=60\; months\)
Given:
A = $11,160r = 8% = 0.08t = 36 months = 3 yearsSubstitute the given values into the formula and solve for P:
\(\implies 11160=P(1+0.08 \cdot 3)\)
\(\implies 11160=P(1.24)\)
\(\implies P=\dfrac{11160}{1.24}\)
\(\implies P=\$9000\)
Given:
A = $3,207P = $3,000t = 18 months = 1.5 yearsSubstitute the given values into the formula and solve for r:
\(\implies 3207=3000(1+r \cdot 1.5)\)
\(\implies \dfrac{3207}{3000}=1+1.5r\)
\(\implies 1.069=1+1.5r\)
\(\implies 1.5r=1.069-1\)
\(\implies 1.5r=0.069\)
\(\implies r=\dfrac{0.069}{1.5}\)
\(\implies r=0.046\)
\(\implies r=4.6\%\)
Therefore, the completed table is:
\(\begin{array}{|c|c|c|c|}\cline{1-4} \vphantom{\dfrac12} \rm BALANCE & \rm PRINCIPAL & \rm INTEREST \; RATE & \rm TIME \\\cline{1-4} \vphantom{\dfrac12} \$5,000 & \$4,000 & 5\% & \rm 60 \; months\\\cline{1-4} \vphantom{\dfrac12} \$ 11,\!160 & \$9,000 & 8\% & \rm 36 \; months \\\cline{1-4} \vphantom{\dfrac12} \$3,207 & \$3,000 & 4.6\% & \rm 18 \; months\\\cline{1-4} \end{array}\)

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Simplify the expression.
2/3y+1/6y+y
Answer:
I'm not sure, but I am thinking it is 1 5/6y
Step-by-step explanation:
The simplified form of the given expression is \(\frac{11y}{6}\) OR \(1\frac{5}{6}y\)
From the question,
We are to simplify the expression 2/3y+1/6y+y
First, we will write the given expression properly
The expression can be written as
\(\frac{2}{3} y+\frac{1}{6} y+ y\)
The expression can be simplified as follows
\(\frac{2}{3} y+\frac{1}{6} y+ y\)
This becomes
\(\frac{2 \times 2y + 1 \times 1y + 6 \times y}{6}\)
Then, we get
\(\frac{4y+1y+6y}{6}\)
\(\frac{11y}{6}\)
OR
\(1\frac{5}{6}y\)
Hence, the simplified expression is \(\frac{11y}{6}\) OR \(1\frac{5}{6}y\)
