Answers

Answer 1

Answer:

120

Step-by-step explanation:

boys : girls

8 : 5

x : 75

to find x, take 75 and divide it by 5:

75 ÷ 5 = 15

(you do this to determine how you can go from 5 to 75)

take the qoutient and multiply it by 8:

15 × 8 = 180

The dimensions of a lawn shaped like a trapezoid are given in meters. 18 meters, 4 meters, 5 meters, 12 meters. What is the area of the lawn in square meters?

Answers

Answer:

the  area of the lawn in square meters is  60 meters^2

Step-by-step explanation:

The computation of the area of the lawn in square meters is shown below

= 12 meters × 5 meters

= 60 meters ^2

Here we multiply the two sides so that the area of the lawn could be come

Hence, the  area of the lawn in square meters is  60 meters^2

Answer:

x = 7, y = 16

Step-by-step explanation:

From the diagram shown;

2x+5 = x+12

collect the like terms

2x-x = 12 - 5

x = 7

Similarly, y - 4 = x+5

y-4 = 7+5

y - 4 = 12

y - 12+4

y = 16

hence x = 7, y = 16

Tom's father is carpeting a rectangular room that has an area of 240 square feet. The width of the room is 15 feet. How long is the room?

Calculate the area of triangles using two different methods. figures are now drawn to scale.

Answers

Answer:

the formula is base times hight divided by two so use the formula to sovle the problem

Step-by-step explanation:

The area of the triangles given are 52.5 feet² and 369 inches² respectively.

What is Area?

Area of a two dimensional shape is the total region which is bounded by the object's shape.

The basic formula to calculate the area of a triangle is,

Area = [tex]\frac{1}{2}[/tex] × base × height

1. Base = 12 + 3 = 15 feet

Altitude/height = 7 feet

Area = [tex]\frac{1}{2}[/tex] × 15 × 7 = 52.5 feet²

2. Calculating the area of two separate triangles and then adding it,

Area = ([tex]\frac{1}{2}[/tex] × 32 × 18) + ([tex]\frac{1}{2}[/tex] × 9 × 18)

        = 288 + 81

        = 369 inches²

Hence the area of the two figures is 52.5 feet² and 369 inches² respectively.

78% of drivers use their turn signal. Part A: What is the probability that exactly 3 drivers use their turn signal if a police officer pulls over five drivers? (5 points) Part B: What is the probability the next driver using their turn signal that the police officer pulls over if the fifth driver? (5 points) (10 points)

Step-by-step explanation:

p = 0.78

1 - p = 0.22

P(x = 3)

Using the binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 3) = 5C3 * 0.78^3 * 0.22^2

P(x = 3) = 10 * 0.78^3 * 0.22^2

P(x = 3) = 0.2297

Rob is saving to buy a new MP3 player. For every $12 he earns babysitting, he saves $9. On Saturday, Rob earned $36 babysitting. How much money did he save?

Answers

Answer:

$27

Step-by-step explanation:

Set up a proportion where x is the amount of money he saved:

[tex]\frac{12}{9}[/tex] = [tex]\frac{36}{x}[/tex]

Cross multiply and solve for x:

12x = 324

x = 27

So, he saved $27

Suppose ABCD is a rhombus with AB = 12 inches. The midpoints of its sides are joined to form a quadrilateral. What type of quadrilateral is formed?

Answers

Answer:

A rectangle

Step-by-step explanation:

The given parameters are;

The quadrilateral ABCD is a rhombus;

The length of the sides of the rhombus = 12 inches

The lengths of the sides of a rhombus are equal

The opposite interior angles of the rhombus are equal

The length of each midpoint from the vertex = 12 in./2  = 6 in.

Therefore, we have;

The line joining the midpoints form a quadrilateral with the length of the opposite sides equal

The sum of the interior angles of the rhombus = 180°

From the diagram created with Microsoft Visio, we have;

4·a + 4·b + 360 = 4 × 180 = 360 + 360

4·a + 4·b = 360

a + b = 90°

We have;

The interior angles of the quadrilateral formed = x

a + b + x = 180° Sum of angles on a straight line

∴ x = 180° - (a + b) = 180° - 90° = 90°

x = 90°

Therefore, the interior angles of the quadrilateral formed = 90°

The quadrilateral formed having equal opposite sides, and all interior angle of 90° each is a rectangle
