Answers

Answer 1

Answer:

Answer:

0.700

Step-by-step explanation:

if you do 0.100x12=1.2 -0.500=0.700

3 ( 4d + 1 ) - 9d = 6 - 2d

Answers

3(4d+1)-9d=6-2d
12d+3-9d=6-2d
3d+3=6-2d
5d=3 /:5
d=3/5

Answer:

d=3/5

Step-by-step explanation:

3 ( 4d + 1 ) - 9d = 6 - 2d

12d + 3 - 9d = 6 - 2d

12d - 9d + 2d = 6 - 3

5d = 3

d = 3/5

d = 0.6

Tyler simplified the expression. His procedure is shown below.

Answers

Answer:

B:Both powers should be in the denominator with positive exponents.

Step-by-step explanation:

We are given that Tyler simplified an expression

$x^(-3)y^(-9)$

We have to find an error which Tyler makes in her simplification

Step 1: $x^(-3)y^(-9)$

Step 2: $(1)/(x^3)\cdot y^(-9)$

Step 3: $(1)/(x^3y^9)$

Hence, Tyler's error is both exponents should be denominator with positive exponents.

Answer:B:Both powers should be in the denominator with positive exponents.

Answer:

Step-by-step explanation:

Tyler correctly rewrote x^(-3) as ------- , but

x³

he incorrectly wrote y^(-9) as ---------

y^(-9)

Both x^9 and y^9 should be in the denominator. This corresponds to the 2nd given possible answer.

A rectangular, above ground swimming pool is 18 feet long, 9 feet wide, and 54 inches deep. One cubic foot of water weighs about 62.4 pounds. What is the total weight of the water in the pool when it is completely filled? (show/explain how you got your answer)A. 158 lbs
B. 729 lbs
C. 8748 lbs
D. 45489.6 lbs

Answers

What is the total weight of the water in the pool when it is completely filled?

V = L * W * D
V = 18 * 9 * 54/12
V = 18 * 9 * 4.5
V =729 cubic feet

729 cubic feet of water times 62.4 pounds = 45489.6 pounds

The surface area of a shape is basically the sum of all the areas on a shape.

We’ve been given that the side is 17 mm.

An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.

Once we do that we get that the area of 1 square is 289.

Since there are 6 squares we need to multiply 289 by 6.

Therefore,

SA=1734mm^2

the surface area is 1734mm
hope this helps:)

Answers

Multiply the first digit by 3 then subtract the answer by 2. Rule: x 3 - 2

The patter is multiply the prior number by 3, and subtract two from the following number. The next 3 numbers would be 84,82,246
