Answer:

36*sqrt(3)

Step-by-step explanation:

Remark

Use the Pythagorean theory to find the height. Use that height to find the area of the rectangle and the triangle Or

You can find the area of the trapezoid which requires only 1 step after you find the height.

Height

c = 8

b = 4

a = ?

a^2 + b^2  =  c^2

a^2 + 4^2 = 8^2

a^2 + 16 = 64

a^2 = 64 - 16

a^2 =  48

a^2 =  16 * 3

sqrt(a^2) = sqrt(16*3)

a = 4 * sqrt(3)

That's the height

Trapezoid

b1 = 7

b2 = 7 + 4 = 11

h = 4*sqrt(3)

Area = (b1 + b2)*h / 2

Area = (7 + 11)* 4*sqrt(3)/2

Area = 18 * 2 sqrt(3)

Area = 36* sqrt(3)

Answer:

option 2] 7. 1

Step-by-step explanation:

Perimeter of square is 20.

therefore,

[tex]perimeter \: = 4 \times side \\ therefore \: 20 = 4 \times side \\ \: \: \: \: \: \: side = \frac{20}{4} \: = 5 [/tex]

the diagonal and the Two adjacent sides of the square form a right angle triangle, so,

By hypotenuse theorem,

[tex] {iagonal}^{2} \: = {side1}^{2} + {side2 }^{2} \\ \: \: \: \: \: \: \: \: = {5}^{2} + {5 }^{2} \\ = 25 + 25....(as \: suare \: has \: equal \: sides \: i.e \: 5) \\ = 50 \\diagonal = \sqrt{50} \\ = \sqrt{25 \times 2} \\ = 5 \sqrt{2 } \\ = 5 \times 1.414 \\ = 7.07 \\ = approx \: 7.1[/tex]

Answer:

4720

Step-by-step explanation:

We already know what we will be looking  at there are 4.72 meters we first need to figure out weather milli"s are bigger or smaller than meters so we know weather we are multiplying or dividing . A Milli is a one thousand of a meter we will be multiplying 1000 x 4.72 The point will move over a bit and your answer is 4720

Answer:

Monthly payment= $1,076.37

Step-by-step explanation:

Giving the following information:

$175,000 at 6.24% for 30 years.

First, we need to calculate the future value of the loan. We need to use the following formula:

FV= PV*(1+i)^n

PV= 175,000

n= 12*30= 360 months

i= 0.0624/12= 0.0052

FV= 175,000*(1.0052^360)

FV= $1,132,220

Total interest= 1,132,220 - 175,000= $957,220

Now, we can calculate the monthly payment:

Monthly payment= (FV*i)/{[(1+i)^n]-1}

Monthly payment= (1,132,220*0.0052) / [(1.0052^360) - 1]

Monthly payment= $1,076.37

Answer: 3.579 × 10^5

Step-by-step explanation:

Answer:

First box: 1

Second box: 110

Third box: 2

Step-by-step explanation:

Any number divided by itself is 1. So, 65 divided by 65 = 1

Any number multiplied by 1 is the same number. So, 1 x 110 = 110

Or, you can simply do 65 times 2 to get 110

Answer:

y=-17

Step-by-step explanation:

y=mx

20.4=m×6

20.4÷6=m

3.4=m

y=3.4×-5

y=-17

The value of the variable 'y' at x = 5 will be 17. Then the correct option is A.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

If y varies directly with x. Then we have

y ∝ x

y = kx

At x = 6 and y = 20.4, then the value of the constant k is calculated as,

20.4 = k(6)

k = 20.4 / 6

k = 3.4

Then the equation is given as,

y = 3.4 x

The value of the variable 'y' at x = 5 will be calculated as,

y = 3.4 (5)

y = 17

The worth of the variable 'y' at x = 5 will be 17. Then, at that point, the right choice is A.
