help with these four questions please!!

Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

|  —                                 —  |

|   Point A = 1 * 30° = 30°    |         ⇒

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Answer:

-10 over 27

Answer:

\( \boxed{ \bold{ \huge{ \boxed{ \sf{ - \frac{10}{27}}}}}} \)

Step-by-step explanation:

\( \sf{ - 3 \frac{1}{3} \div 9}\)

Convert the mixed number into improper fraction

\( \longrightarrow{ \sf{ - \frac{ 3 \times 3 + 1}{3} \div 9}}\)

\( \longrightarrow{ \sf{ - \frac{ 9 + 1}{3} \div 9}}\)

\( \longrightarrow{ \sf{ - \frac{ 10}{3} \div 9}}\)

Multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator

\( \longrightarrow{ \sf{ - \frac{ 10}{3} \times \frac{1}{9}}} \)

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator

\( \longrightarrow{ \sf{ - \frac{10 \times 1}{3 \times 9}}} \)

\( \longrightarrow{ \sf{ - \frac{10}{27}}} \)

Step-by-step explanation:

10)We have to calculate the average speed if we know the distance and time that Johnatan can jog. The distance

distance=3 2/5 miles = 3.4 miles.

Time=7/8 hour = 0.875 h

Then we will use the formula for the average speed ( velocity )

velocity=distance/time. v = 3.4 m / 0.875 h = 3.866 mph

so therefore The average speed is 3.866 mph.

11) divide 120 / 7/4 (remember 120 = 120/1)

Which means you have to cross multiply (an important part on fraction division, that is, your division would be 120x4 / 1x7).

Then 120x4= 480

And 1x7 = 7

Then you get 480/7, which is the same as 68 4/7 mph

12)8 1/3=25/3

   25/3 pages of a book in 10 minutes

   Multiply both numbers by the reciprocal of 10, which is 1/10

  25/3 x 1/10=25/30=5/6

  10 x 1/10=1

So, Charlotte reads 5/6 pages of a book in 1 minute.

13)45 1/2% = 45.5% = 45.5/100 = 91/200

30 1/4% = 30.25% = 30.25/100 = 121/400

Answer:

=8/13

Step-by-step explanation:

There are a total of 2+6+8+10  = 26 students

There are 6+10 = 16 students that do not have a brother

P( not have a brother) = number that do not have a brother / total

                                     =16/26

Step-by-step explanation:

a

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Answer:

(3/2 m)^2 -(5n)^2^

Step-by-step explanation:

Answer: 9m^2 / 4  -  25n^2

Step-by-step explanation:

Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

Answer: 40 inches squared

Labels are in the pictures

Step-by-step explanation:

To find the surface area, find the area of each side.

Square (base) : side * side = 4*4 = 16

Triangle (sides) : (base * height)/2

Assuming each side is a isosceles triangle, the base 4/2 = 2

(2*6)/2 = 12/2 = 6

Since there are 4 triangles, we can multiply 6 by 4 to get the combined area. We then add the area of the square to get the final result.

6*4 + 16 = 24+16 = 40

Answer:

Step-by-step explanation:

Answer: 1/2, 0.51, 11/20

Step-by-step explanation:

Use 100 as a common denominator so you can compare all the numbers in like terms:

1/2 = 50/100

0.51 = 51/100

11/20 = 55/100

Answer:

\(\frac{1}{2} 0.51, \frac{11}{20}\)

Step-by-step explanation:

First, you want to change the decimal into a fraction.  0.51= \(\frac{51}{100}\)

Then, find the common denominator.  In my example, I used 100.  Find the equivalent fraction for the fractions with 100 as their denominator

\(\frac{11}{20} = \frac{55}{100} \\\\\ \frac{1}{2} = \frac{50}{100}\)

Next, line them up in order of their numerators

\(\frac{50}{100} \frac{51}{100} \frac{55}{100}\)

Finally, match the new fraction with their reduced fraction or decimal:

\(\frac{1}{2} = \frac{50}{100} \\\\0.51 = \frac{51}{100} \\\\\frac{11}{20} = \frac{55}{100}\)

Answer: .28, .16, 0, .34

Step-by-step explanation:

Answer:

A: 80 and B: 5.5

Step-by-step explanation:

For A, just multiply 20 and 4 and which you would get 80 miles. And for B, if 1 inch is equal to 20 miles, you can divide 110 and 20 but the answer will be 5.5 rather than 5.

I think this is right but if you can, try and see if it’s correct later.
