A store is designing the space for rows of nested shopping carts. Each row has a starting cart that is 4 feet long, followed by

stich3 [128]

Answer:

Each nested carts is of the length of 1.5 feet.

Step-by-step explanation:

Each row has a starting cart that is 4 feet long, and the nested carts are next to it.

It is measured that a row of 13 nested carts has a length of 23.5 feet.

Therefore, the original length of 13 nested carts is (23.5 - 4) = 19.5 feet.

So, each nested cart add to the length of the row, $\frac{19.5}{13} = 1.5$ feet.

Again, a row of 18 nested carts to be 31 feet long.

Therefore, the actual added length of 18 nested carts is (31 - 4) = 27 feet.

So, each nested cart add to the length of the row, $\frac{27}{18} = 1.5$ feet.

So, each nested carts is of the length of 1.5 feet. (Answer)

Louisa ran at an average speed of five miles per hour along an entire circular park path. Calvin ran along the same path in the

docker41 [41]

Answer:

15 miles

Step-by-step explanation:

Let $x$ be the miles in the circular park path, $t_{L}$ the time Louisa takes to finish and $t_{C}$ the time Calvin takes to finish both in hours.

Then $x$ , the longitude is equal to the velocity times the time used to finish. So

$x=5t_{L}$

$x=6t_{C}$

And the difference between Louisa's time and Calvin' time is 30 minutes, half an hour. So:

$t_{C}=t_{L}-0.5$

Three equations, three unknowns, the system can be solved.

Equalizing the equation with x :

$5t_{L}=6t_{C}$

In this last equation replace $t_{C}$ with the other equation and solve:

$5t_{L}=6(t_{L}-0.5)\\ 5t_{L}=6t_{L}-3\\ 3=6t_{L}-5t_{L}\\ 3=t_{L}\\ t_{L}=3$

With Louisa's time find x:

$x=5t_{L}\\ x=5(3)\\ x=15$

If a translation maps point (3, 2) to (5,3); or T:(3, 2) - (5,3), indicate the image for (2,4)

Zinaida [17]

Answer:

A

Step-by-step explanation:

Note that for (3, 2) → (5, 3)

The x- coordinate of the image is 2 more (+ 2) than the original and the y- coordinate of the image is 1 more (+ 1) than the original, that is

(x, y ) → (x + 2, y + 1 ) ← rule to obtain image, hence

(2, 4 ) → (2 + 2, 4 + 1 ) → (4, 5 ) → A
