Answer:

6.5:7.5, or 1.3:1.5

Step-by-step explanation:

Simply find the number of hours studied for math (6.5) and hours studied for English (7.5) and put it into ratio form (6.5:7.5). Then simplify to get 1.3:1.5. Watch out for the wording.

Answer:

1.3 : 1.5

Step-by-step explanation:

Math : English

6.5 : 7.5 = 1.3 : 1.5

Answer:

x = 48 (in degrees, I assume)

Step-by-step explanation:

Note that the two horizontal lines have those extra arrowheads on them? The red ones? That notation means those lines are parallel to each other.

In geometry, we learn that when two parallel lines are crossed by a third line (called a 'transversal'), alternate interior angles are congruent.

The two angles with labeled quantities are alternate exterior angles. They are 'alternate' because they are on opposite sides of the transversal line, and 'exterior' because they are above and below the the two horizontal lines, not contained in the interior area between them.

Therefore,       2x + 2 = x + 50

                         -x - 2 = -x -  2

                          x       =    48

Answer: $34

Step-by-step explanation:

39 x 0.2 = 7.80, the discount

39 - 7.80 = 31.20

31.20 x 0.09 = 2.80, the tax

31.20 + 2.80 = 34

Answer:

44% of students

Step-by-step explanation:

because the sum of all the students = 50, we jsut need to multiply by 2 to get 100 (which is the easiest number to get a percentage from. because we multiplied 50 by 2 we must multiply 22 by 2 which gives us 44. 44/100 =44%

Answer:

44%

Step-by-step explanation:

to solve for this you simply add the numbers together in order to get the total then once you find the total you didved the number you're trying to find the percent for by the total

Answer:

14 units²

Step-by-step explanation:

The area of the shape = area of a triangle

Area of triangle = ½ × base × height

base = 7

height = 4

Plug in the value into the formula:

Area = ½ × 7 × 4

Area = ½ × 28

Area = 14 units²

Answer:

Angle x is 38.

Step-by-step explanation:

If its congruent it means it is equal. Vertical angles are equal to each other.

The measure of x is 38°.

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

Vertical angles are congruent.

x° and 38° are vertical angles.

Now,

x° = 38°

Thus,

The value of x is 38°.

[tex]\frac{13}{20}[/tex], or 0.65 miles.

Convert both to common denominator, then add together.

They have a common denominator of 20.

[tex]\frac{1}{4}[/tex] × [tex]\frac{5}{5} = \frac{5}{20}[/tex]

[tex]\frac{2}{5}[/tex] × [tex]\frac{4}{4} = \frac{8}{20}[/tex]

[tex]\frac{5}{20} + \frac{8}{20} = \frac{13}{20}[/tex]

Answer:

I would walk [tex]\frac{13}{20}[/tex] or 0.65 miles.

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{5}{20}[/tex] + [tex]\frac{8}{20}[/tex] = [tex]\frac{13}{20}[/tex] or 0.65

Answer:

89·98 mph

Step-by-step explanation:

First, we get the circumference of the tires:

Circumference = [tex]\pi[/tex] × (radius × 2)

Circumference = 3.142 × (1·5 × 2)

Circumference = 3·142 × 3

Circumference = 9·426 ft

The circumference of the tire is equal to one round.

      1 round = 9·426 ft

840 rounds = ?

We cross multiply to get the length that the tires would cover in a minute

= 840 × 9·426

       1

    1 minute = 7917·84 ft

60 minutes = ?

60 × 7917·84

          1

= 475070·4 ft

      5280 feet = 1 mile

475070·4 feet = ?

475070·4 × 1

     5280

475070·4 ÷ 5280 = speed of the car in mph

89·97545

Round this off to 2 decimal places...

= 89·98 mph

Answer:

original number = 53

Step-by-step explanation:

In two digits number:

Let the tens place digit be x and units place digit be y.

So,

Original number = 10x + y

Number obtained after reversing the digits = 10y + x

According to the first condition:

x + y = 8.... (1)

According to the second condition:

10y + x = 10x + y - 18

10y + x - 10x - y = - 18

9y - 9x = - 18

-9(x - y) = - 18

x - y = - 18/(-9)

x - y = 2.......(2)

Adding equations (1) & (2), we find

x + y + x - y = 8 + 2

2x = 10

x = 10/2

x = 5

Plug x = 5 in equation (1), we find:

5 + y = 8

y = 8 - 5

y = 3

10x + y = 10*5 +3 = 50 + 3 = 53

Hence, original number = 53
