Answer:

Area = 240 cm²

Step-by-step explanation:

Area of the shape = area of rectangle + area of triangle

= L*W + ½*bh

L = 18 m

W = 10 m

b = 10 m

h = 30 - 18 = 12 m

Plug in the values

Area of the shape = 18*10 + ½*10*12

= 180 + 60

= 240 cm²

Answer:

I don't know the answer to this but

Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

Step-by-step explanation:

The number of locker at school have decorated name tags is 147. Therefore, option D is the correct answer.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, the school has 6 rows of lockers. Each row has 35 lockers.

For the first 5 rows, all of locker are taken.

Number of lockers in 5 rows are 35×5=175

For the last row, 3/5 of the locker are taken is

3/5 ×35 =21

So, the total number of lockers taken = 175+21

= 196

3/4 of all locker that are taken have decorated name tag

Now, 3/4 ×196

= 3×49

= 147

Therefore, option D is the correct answer.

Answer:

The answer is 69.5

Step-by-step explanation:

First u wanna find the area of the rectangle and since it already gives you the the height and width you want to multiply them together 13×4= 52

meanwhile triangle is 5ft tall and the base is 7ft

using the formula to solve for area of a triangle you would multiply height and base and divide by 2

you should end up with 17.5 then u add that to 52 and get 69.5 ♡ Hope this helps.

Answer:

15

Step-by-step explanation:

Answer:

each section takes 15 minutes long

Step-by-step explanation:

An equation you can use to get this is 45 ÷ 3 = x

x = 15

so the answer to the equation would be 45 ÷ 3 = 15

Answer:

The area of a triangle uses the equation:

A = ab/2

a = 12

b = 9

A = 12 * 9 / 2

A = 54 inches

54 / 3 = 18

He needs 18 feet of paper

Answer: 8

Step-by-step explanation: you have to cross multiply 6 and 4 to get 24. 24/3 is 8

Answer:

140

Step-by-step explanation:

V=whl=7·4·5=140cm³

Answer:

140cm^3

Step-by-step explanation:

It is 140 because volume is base x length x height so 7 x 5 x 4 = 35 x 4 = 140 cm cubed so 140cm^3

Answer:

Step-by-step explanation:

Answer:

The answer is -18

Step-by-step explanation:

He starts off with $100 in his account. He then take so $45 to purchase a pair of jeans, so we have to subtract 45 from 100 and that gives us $55. He now has $55 in his account, he then adds another $25 to his account, so we have to add 25 to 55 and that will give us $80 in his account. Finally on Friday he takes out $98 of his checking account. He takes out more than he has in his checking account so we have to subtract $80 from $98 and we will get $18, but since he takes out more than what he has in his account the answer will be negative and we end up with -18 dollars in his checking account.

Answer:

63

Step-by-step explanation:

To find the area of a trapezoid you have to use the formula

a+b/2 h

So we would substitute them

3 + 15 / 2 x 7

Which would equal

Answer:

10 x X - 5 = -13

Answer:

Step-by-step explanation:

10x-5= -13

10x= -13+5

10x= -8

x= 10/-8

x= -1.25 or 5/-4

Answer:

ACB=44°

DCE=35°

BCD=101°

Step-by-step explanation:

ACB is a triangle and all triangles are 180 degrees

78+58=136

180-136=44

DCE is also a triangle

85+60=145

180-145=35

a straight line is 180 degrees, we already know what the other two is.

35+44=79

180-79=101

Answer:

1. half angle

2. x

Step-by-step explanation:

The missing parts of the proof is the variable x.

Trigonometric functions are those functions which are the ratio of the sides of a right angled triangle.

Given,

sin² (x) = [1 - cos (2x)] / 2

We have to prove sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]

First, we have

sin² (x) = [1 - cos (2x)] / 2

Substituting x/2 in place of x, we get,

sin² (x/2) = [1 - cos (2x/2)] / 2

sin² (x/2) =  [1 - cos (x)] / 2

sin² ([tex]\frac{x}{2}[/tex]) = [tex]{\frac{1-cos (x)}{2} }[/tex]

Taking square root on both sides,

sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]

Hence it is proved.
