So a man runs 7 feet in one second, how much time does it take to run one foot?

1 answer:

3 0

Your answer is 142.86 milliseconds rounded to two decimal places.

As 1 second is equal to 1000 milliseconds, we can write the ratio 7:1000 to represent feet to milliseconds. We can then see that to get 1 foot, we just have to divide 1000 by 7, which gives us 142.8517, or 142.86 to two decimal places.

I hope this helps!

Electricity City increases the price of televisions by 25%. If a television now sells for

Burka [1]

Answer:

340

Step-by-step explanation:

As it was increased by 25%, $425 is 125% of the original price, so we can get back to 100% by dividing 425 by 5 [85], so 85 is 25% of the price. We can now get the original price by subtracting 85 from 425 (or you could multiply 85 by 4) which is 340

You can check this answer by multiplying 340 by 1.25

If the answer is 425, then it is correct, else, not. [it is]

Miguel sells insurance. He earns a 6% commission on each sale he makes. Miguel has a goal of earning $600 in commissions. Miguel

tankabanditka [31]

Answer: $12,000

Step-by-step explanation:

Miguel makes 6% on every sale he makes and wants to make $600 in commissions.

The amount he needs to sell is therefore the amount that has $600 as 5% of it.

Assume the amount of insurance needed is x.

x * 5% = 600

x = 600 / 5%

x = $12,000

30 POINTS NEED HELP

KatRina [158]

a. The expression y=5x represent the number of small marbles she has.

b. The expression z=3x+2 represents the number of large marbles she has.

c. Amy has 310 small marbles, 62 medium marbles and 188 large marbles.

Step-by-step explanation:

a. Let x represent the number of medium marbles Amy has. Write an algebraic expression to represent the number of small marbles she has.

Medium marbles = x

Let,

Small marbles = y

According to given statement;

She has five times as many small marbles as medium marbles.

y = 5x Eqn 1

The expression y=5x represent the number of small marbles she has.

b. Write an algebraic expression to represent the number of large marbles she has.

Let,

Large marbles = z

The number of large marbles is two more than three times the number of medium marbles.

z = 3x+2 Eqn 2

The expression z=3x+2 represents the number of large marbles she has.

c. If Amy has a total of 560 marbles, how many of each size does she have?

x+y+z= 560 Eqn 3

Putting value of y and z from Eqn 1 and 2 in Eqn 3

$x+(5x)+(3x+2)=560\\x+5x+3x+2=560\\9x=560-2\\9x=558$

Dividing both sides by 9

$\frac{9x}{9}=\frac{558}{9}\\x=62$

Putting x=62 in Eqn 1

$y=5(62)\\y=310$

Putting x=62 in Eqn 2

$z=3(62)+2\\z=186+2\\z=188$

Amy has 310 small marbles, 62 medium marbles and 188 large marbles.

What is the probability that a randomly selected person supports the new station??

mezya [45]

Answer:

.52

Step-by-step explanation:

We can write an equation

supports/all

we can see that 27 males and 25 females support which means that

27+25= 52 total people support

now we just need to find the number of people surveyed

we do this by summing everything

27+25+18+13+5+12=100

52/100 = .52
