Can you help me and explain how to do it? please​

Answer:

B - 10 (possibly and hopefully)

the base is 20 ft so the triangular base is 69 feet.

Answer:

x = 4

Step-by-step explanation:

The easiest way to do this is to look at the vertical angles. (15x)º has its own vertical angle, and the part with (8x-2)º and 90º does as well.

Also, every angle will add up to 360º, which is a crucial part of the equation

Do 15x + 15x + 90 + 90 + 8x - 2 + 8x - 2 = 360

This can be simplified into this once you combine like terms:

46x + 176 = 360

Subtract 176 from 360, which will give you:

46x = 184

Divide by 46 on both sides, resulting in:

x = 4

To check the answer, plug in 4 for x:

15(4) + 15(4) + 90 + 90 + 8(4) - 2 + 8(4) - 2 = 360

60 + 60 + 90 + 90 + 32 - 2 + 32 - 2 = 360

120 + 180 + 60 = 360

360 = 360, x is 4

Hope this made sense!

Answer:

9

Step-by-step explanation:

Split up the shape into 2 seperate shapes (I did a trapezoid and)

Rectangle:

1*4 = 4

Trapezoid:

3 - 1 = 2 (for trapezoid's height)

4 - 2 = 2 (for trapezoid's shorter base)

(3 * [tex]\frac{1}{2}[/tex]) * (2 + 4) =

1.5 * 6 = 9

Answer:

-20

Step-by-step explanation:

let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20

Answer: The number is 35

If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.

Step-by-step explanation:

Let the missing number = y

To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.

Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.

Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.

Thus,

2/5 of 14/y

2/5= 14/y

(2 x y) = (5 x 14)

(2y) = (70)

2y = 70

Since we are looking for value of y, divide both sides by the value beside y

Thus,

2y/2 = 70/2

y = 35

Therefore, the missing number is 35

Answer:

£234.90

Step-by-step explanation:

270(1-13/100)

lets break it down:

step 1=  13/100=0.13

step 2= 1-0.13=0.87

step 3= 270 x 0.87=234.9

final answer=£234.90

Answer:

8 hours

Step-by-step explanation:

t = time for Bob and Nina to make 60 leashes

Bob = 7 in 2 hr  = 3.5 in 1 hr

Nina = 4 in 1 hr

3.5 + 4 = 7.5 leashes per hour

t = 60/7.5 = 8 hours

Answer:

y = -1/3

x = 0

Step-by-step explanation:

3x-6y = 2    then 3x = 2+6y,   x=(2+6y)/3

4x+3y = -1

substitute for x

4(2/3+2y)-6y = 2

8/3+8y-6y = 2

reduce

2y = 2-8/3

2y = -2/3

divide both sides by 2

y = -1/3

4x+3(-1/3) = -1

4x = 0

x = 0
