Can someone help real quick?A motor spins 310 times in 62 s. The number of spins varies directly with the length of time the motor is running.

How long will it take the motor to spin 495 times?

_____s

Answers

Answer 1

Answer: so 310:62
treat as fraction
310/62
simplify by finding factors
310:2 times 5 times 31
62:2 times 31

we see a 2 times 32 in both so we divide top and bottom by (2 times 31) or 62
5/1=5

5 spins per second

5:1 is ratio

so if 495 spins then
5/1=495/x
multiply both sdies by x
5x=495
divide boht sides by 5
x=99

the answer is 99 seconds

7% of 120 (Need work shown)

Answers

1% of 120 is 1.2, so 7 *1.2 = 8.4

Also you could set up the proportion 7/100 = x/120 and solve for x.

120=100%

x= 7 %

cross-multiply

100x= 120*7

100x= 840

x= 840/100

x= 42/5

x= 8.4

Therefore 7% of 120 is 8.4

Lucy spent 4 hours babysitting last week. her sister Maria spin blank times as many hours babysitting as Lucy that same week. what are all values for blank Maria babysits more hours then her sister Lucy

Answers

Time spent babysitting by Lucy = Tl = 4 hours

Time spent babysitting by Maria = Tm = x * 4 hours

Now we need to determine for what values of x is Tm > Tl

⇒ x * 4 > 4

⇒ x > 1

So for x > 1, Mary spends more time babysitting than Lucy does

4. 5

Please give me the answer if you know it, or help me figure it out.

Answers

I'll give you the linear equation:

y = mx + b ; where m is the slope of the line ; b is the y-intercept.

y = -5x - 2

m = -5
b = -2

-5 is the slope of the line while -2 is the y-intercept. Choice 1.) -5

Answer:

-5

Step-by-step explanation:

because -5 is the answer and it is choice 1 i didi quiz and -5 is good answer
