A person on a moving sidewalk travels 40 feet in 8 seconds. The moving sidewalk has a length of 200 feet. How long will it take

beks73 [17]

Answer:

The man covers 200 ft in 40 seconds.

Step-by-step explanation:

A person is moving on the sidewalk from one end to the other end.

He walks 40 feet in 8 seconds.

Therefore his speed = $\frac{distance covered}{time}$

= $\frac{40}{8}$

= 5 ft/ $s^{2}$

He covers the sidewalk distance at a rate of 5 feet every second.

To calculate the time taken to cover 200 ft,

time = $\frac{distance to be covered}{speed}$

time = $\frac{200}{5}$

<u>time = 40 seconds</u>

Hence the man covers 200 ft in 40 seconds.

If angle 4 is 52.7, what are the measures of angles 1,2, and 3?

shusha [124]

Answer:

127.3
52.7
127.3
52.7

Step-by-step explanation:

Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).

52.7 + x = 180

x = 127.3

Best of Luck!

What are the values of x and y if you answer is not a whole number write it as a decimal and round if neccasasry

den301095 [7]

a) 3x + 5y = 26

b) 2x + 2y = 12

First, we need to find a way to equate either the x terms or the y terms in each equation. a) 6x + 10y = 52

b) 6x + 6y = 36

Then take equation b) from the equation a) to eliminate the x component.

a) 6x + 10y = 52

- b) 6x + 6y = 36

0x + 4y = 16

y = 4 ?

Then substitute the value of y into either equation to find the value of x.

b) 2x + 2y = 12

2x + (2x4) =12

2x + 8 = 12

2x = 4

x = 2

I hope this new information i read helps you maybe understand it and as an example!

A school is organizing a cookout where hotdogs will be served. The hotdogs come in small packs and large packs. Each small pack

Bond [772]

The number of small packs is 2 and the number of large packs is 7

Step-by-step explanation:

A school is organizing a cookout where hot dogs will be served. The hot dogs come in small packs and large packs

Each small pack has 8 hot dogs
Each large pack has 18 hot dogs
The school bought 5 more large packs than small packs, which altogether had 142 hot dogs

We need to find the number of small packs purchased and the number of large packs purchased

Assume that the number of the small packs is x and the number of the large pack is y

∵ There are x small packs

∵ Each small pack has 8 hot dogs

∵ There are y large packs

∵ Each large pack has 18 hot dogs

∴ The total number of hot dogs in all packs = 8x + 18y

∵ All packs had 142 hot dogs

- Equate the total number of hot doges by 142

∴ 8x + 18y = 142 ⇒ (1)

∵ The school bought 5 more large packs than small packs

∴ y = x + 5 ⇒ (2)

Now we have system of equations to solve it

Substitute y in equation (1) by equation (2)

∴ 8x + 18(x + 5) = 142

- Simplify the left hand side

∴ 8x + 18x + 90 = 142

- Add like terms in the left hand side

∴ 26x + 90 = 142

- Subtract 90 from both sides

∴ 26x = 52

- Divide both sides by 26

∴ x = 2

- Substitute the value of x in equation (2) to find y

∵ y = 2 + 5

∴ y = 7

The number of small packs is 2 and the number of large packs is 7
