is -3 1/2 a rational number

320 cubic inches

128 cubic inches

448 cubic inches

Step-by-step explanation:

Step 1:

Given,

Dimensions of the first rectangular prism = l * b * h = 16*5*4

[length is 16 as the total length is 20 and the width of the 2nd prism till the dotted line is 4]

Dimensions of the second rectangular prism = l * b * h = 4*4*8

We need to determine  volume of the 2 prisms and the whole figure. The volume of  rectangular prism can be obtained by multiplying the length breadth and the height.

Step 2:

Volume of the first prism = l * b * h = 16*5*4 = 320 cubic inches

Volume of the first prism = l * b * h = 4*4*8 = 128 cubic inches

The volume of the whole figure is the sum of the 2 rectangular prisms = 320 + 128 = 448 cubic inches

75% of b is 12, what is b

75b = 1200

b = 16

80% of c is 20, what is c

80c = 2000

c = 25

200% of d is 18, what is d

200d = 1800

Actually, the other answer the other person put was incorrect.

Step-by-step explanation:

The reason for this being that the correct answer is actually "-5 is a real number". Most all numbers are real numbers, if you haven't gotten into complex numbers yet

Hope this helps even if it's really late, just know that the other answer somebody else put is incorrect.

Answer:

Every 1 Block he is planting 5 tree's.

Step-by-step explanation:

There are multiple ways you can do it but the easiest I prefer is just to divided The Tree's by the Blocks.

Ex: 6 Blocks is 30 trees, Divide 30 by 6 and you get 5 for every block.

Emanuel is planting trees at a rate of 5 trees per block. This is determined by dividing the total number of trees by the total number of blocks planted.

Emanuel is planting trees at a consistent rate. To find this rate, we can set up a simple ratio.

He planted 15 trees in 3 blocks, which simplifies to 5 trees per block. This can be confirmed by looking at the second part of the problem. After 5 blocks, he had planted 25 trees. If we divide the total number of trees by the total number of blocks (25 trees / 5 blocks), we also get 5 trees per block.

Therefore, the rate at which Emanuel is planting trees is 5 trees per block.

The general equation of a circle with centre (h,k) and radius r

(x-h)²+(y-k)²=r²

Here, (x+5)²+(y-13)²= 10

=>{x-(-5)}²+(y-13)²=(√10)²

center: ( -5,13)

radius: √10

option C

Answer:

I think it's the third one. Because it will make both equation's x a opposite value (one is positive and one is negative).

Step-by-step explanation:

Because 2x+3y=1*5= 10x+15y=5 and then 5x+2y=8*-2 = -10x+4y=-16 both equations will cancel the Xs out and then you can solve for Y.

Answer: 15.6

Step-by-step explanation:

At x = –6, y = 11

At x = 3, y = 5

At x = 15, y = –3

At x = –12, y = 15

Solution:

The function is [tex]y=-\frac{2}{3} x+7[/tex].

The domain of the function is {–12, –6, 3, 15}.

Substitute x = –6 in the function to find y.

[tex]$y=-\frac{2}{3} (-6)+7[/tex]

y = 4 + 7

y = 11

Substitute y = 5 in the function to find x.

[tex]$5=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$-2=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = 3

Substitute x = 15 in the function to find y.

[tex]$y=-\frac{2}{3} (15)+7[/tex]

y = –10 + 7

y = –3

Substitute y = 15 in the function to find x.

[tex]$15=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$8=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = –12

At x = –6, y = 11

At x = 3, y = 5

At x = 15, y = –3

At x = –12, y = 15
