Vinvika [58]

Answer:

7/60

Step-by-step explanation:

Here is the full question

Diana works at a clothing store. She sold 1/5 of the total number of green shirts on Monday and 3/12 of the total number of green shirts on Tuesday. What fraction of green shirts did Diana sell on Monday and Tuesday? 27/60 is the answer. Diana sold 2/15 of the total number of green shirts on Wednesday. What is the difference in the fraction of the total number of green shirts that were sold on Tuesday and Wednesday?

fraction of green shirts did Diana sell on Monday and Tuesday =

$\frac{1}{5} + \frac{3}{12}$

$\frac{12 + 15}{60} = \frac{27}{60}$

difference in the fraction of the total number of green shirts that were sold on Tuesday and Wednesday =

$\frac{3}{12} - \frac{2}{15} =\\\frac{15 - 8}{60} \\\frac{7}{60}$

A cat chases a mouse. The cat is originally 4 feet behind the mouse, which is running in the same direction along the same route

Verdich [7]

Step-by-step explanation:

The position of the mouse at time t is 4 + 12t.

The position of the cat at time t is 17t.

When the positions are equal:

4 + 12t = 17t

4 = 5t

t = 0.8

It takes 0.8 seconds.

In science class, Priscilla heats water and measures the temperature of the water every 2 minutes\or data are shown in the table

Dima020 [189]

Answer:

37.5 °C

Step-by-step explanation:

The temperature appears to be increasing linearly at the rate of 5 °C in 2 minutes, or 2.5 °C per minute.

1 minute after 4 minutes, when the temperature is 35 °C, we expect it to be 2.5 °C higher, or 37.5 °C.

16. Solve the equation. Check the solution.

harina [27]

Hi there

a/(a² - 36) + 2/(a-6) = 1/(a+6)
a/(a+6)(a-6) + 2/(a-6) = 1/(a+6)
Now we need to multiply the terms by (a+6)(a-6)
a + 2(a+6) = 1(a-6)
a + 2a + 12 = a - 6
3a + 12 = a - 6
3a - a = -6 - 12
2a = -18
Divide both sides by 2
2a/2 = -18/2
a = -9
Thus, The correct option is A

I hope that's help !

Good luck !
