1507.8 x 8 = 12,506

Answer:

Answer: You've presented two statements in your "question".

One is true and the other is false.

1). Momentum = mass x velocity

The statement is true.

2). 1507.8 x 8 = 12,506

The statement is false.

1507.8 x 8 = 12,062.4

One is true and the other is false.

1). Momentum = mass x velocity

The statement is true.

2). 1507.8 x 8 = 12,506

The statement is false.

1507.8 x 8 = 12,062.4

Jesse is building a spice rack. He cuts three lengths of wood from a 90-centimeter board. The first length is 23.5 centimeters. The second length is 33.3 centimeters. And the third length is 19.45 centimeters. How much of the original board remains after Jesse makes his cuts?

Total length of the wood = 90 centimeter.

Length of the first cut wood = 23.5 centimeters

Length of the second cut wood = 33.3 centimeters

Length of the third cut wood = 19.45 centimeters.

Total length of the woods cut

from the original piece = 23.5 + 33.3 + 19.45 centimeters

= 76.25 centimeters

Amount of original board

that remains after Jesse makes his cuts = 90 - 76.25 centimeters

= 13.75 centimeters

Length of the first cut wood = 23.5 centimeters

Length of the second cut wood = 33.3 centimeters

Length of the third cut wood = 19.45 centimeters.

Total length of the woods cut

from the original piece = 23.5 + 33.3 + 19.45 centimeters

= 76.25 centimeters

Amount of original board

that remains after Jesse makes his cuts = 90 - 76.25 centimeters

= 13.75 centimeters

Answer:

13.75 centimetres

The exponential function f intersects the x-axis at the point (2,0) and intersects the y-axis at the point (0,-5.25) If g(x) = 3x - 2, which statement is true over the interval [0, 2]? The average rate of change of g is equal to the average rate of change of f. The average rate of change of g is greater than the average rate of change of f. The average rate of change of g is less than the average rate of change of f. The average rate of change of f cannot be determined using the information given. NextReset

The rate of change of g is given by its gradient, which is 3.

The average rate of change of f in [0, 2] can be calculated by taking:

So, the average rate of change of f is less than the average rate of change of g in the interval [0, 2].

Statement 2 is correct.

The average rate of change of f in [0, 2] can be calculated by taking:

So, the average rate of change of f is less than the average rate of change of g in the interval [0, 2].

Statement 2 is correct.

a 13 ft ladder is leaning on a tree is on the ground at a distance of 5 ft from the base of the tree. what is the distance, in feet, between the ground and the top of the ladder.

13^2=5^2+X^2

169=25+X^2

144=X^2

X=12

169=25+X^2

144=X^2

X=12

You use pythagorean's theorem. 13 squared equals 169 and 5 squared equals 25. You then take the hypotenuse, 169, and subtract one of the legs, 25, to get 169-25= 144. You take the square root of that and get 12 ft.

What happens to the area of a square when its side length is reduced by half? (a) The new area is an eighth of the original.

(b) The new area is a quarter of the original

(c) The new area is half of the original

(d) All of these.

(e) none of these

Remember, the formula of a square is . If I half x, is the new formula. Because the exponent is around the varialbe(x/2), both are squares. Therefore, the formula is .

Therefore, the new area is B: a quarter of the original.

What is 2m-13=-8m+27

0=-10m+40

10m=40

m=4 is your answer

10m=40

m=4 is your answer

I got -6.67 rounded

2m-13=8m+27

subtract 2m form both sides

-13=6m+27

subtract 27 from both sides and you get

-40=6m

divide -40 by 6

m=-6.67

2m-13=8m+27

subtract 2m form both sides

-13=6m+27

subtract 27 from both sides and you get

-40=6m

divide -40 by 6

m=-6.67

Kevin delivers newspapers in his town every morning. The amount he earns from delivering newspapers is given by y = 30x + 18, where y is the amount he earns in cents and x is the number of houses he delivers newspapers to. However, he is paid a certain amount even if he doesn't deliver any newspapers on a certain day. How much is he paid if he doesn't deliver any newspapers? (x 0, y 0) 20 cents

15 cents

12 cents

18 cents

Y=mx+b, b=y-intercept (value of y when x=0) so if:

y=30x+18

He earns 18 cents if he does not make any deliveries.

y=30x+18

He earns 18 cents if he does not make any deliveries.

If f(x)= -3x-2 ,what is f(-5)

Answer:

f(- 5) = 13

Step-by-step explanation:

To evaluate f(- 5) substitute x = - 5 into f(x)

f(- 5) = - 3 × - 5 - 2 = 15 - 2 = 13
