Answer: 36 and 22 A=396

Step-by-step explanation:

half of 1 diagonal is 18, so the whole diagonal is 36

the other diagonal half is 11 so the whole is 22

put 36 and 22 into the boxes

then solve

$A=\frac{1}{2} (36*22)\\A=396$

Answer:

A = 99 in²

Step-by-step explanation:

Using the given formula with d₁ = 18 and d₂ = 11 , then

A = $\frac{1}{2}$ × 18 × 11 = 9 × 11 = 99 in²

Please helppp i need this done and i dont know what to do

Answer:

FRACTION DECIMAL

1/5( 1*2/5*2=2/10) 0.2

3/10 0.3

1/2(1*5/2*5=5/10) 0.5

7/10 0.7

3/4(3*25/4*25=75/100) 0.75

NOTE: To conert a fraction into decimal, it is required that the denominator be changed into 10, 100, 1000 and so on..... By changing the denominator, we have to first select the appropriate number by which you will be able to convert it into 10, 100 or 1000, and you are also required to multiply that number with the denominator as well as numerator. In the first question, 1/5 we can convert the denoinator into 10, 100 or 1000 as the denominator is 5, whatever you choose, the answer will be correct, so, 1*2/5*2 gives 2/10. Since 10 has one zero, the decimal point moves one time towards the left, which gives 0.2. And you can do the rest according to this way, considering the number of zeroes.

The sum of three numbers $x$ ,$y$, $z$ is 165. When the smallest number $x$ is multiplied by 7, the result is $n$. The value $n$

babymother [125]

You're given

x + y + z = 165

7x = n

n = y - 9

n = 9 + z

and you want to find xyz.

Solve the last three equations for x, y, and z :

7x = n → x = n/7

n = y - 9 → y = n + 9

n = 9 + z → z = n - 9

Substitute x, y, and z into the first equation and solve for n :

n/7 + (n + 9) + (n - 9) = 165

n/7 + 2n = 165

n + 14n = 1155

15n = 1155

n = 77

Now solve for x, y, and z :

x = 77/7 = 11

y = 77 + 9 = 86

z = 77 - 9 = 68

Then the product is

xyz = 11 • 86 • 68 = 64,328
