A printer is printing photos. For every 15 photos, the printer takes 3 minutes.
Alex17521 [72]

Answer:

3:15, 5:25, 7:35, 8:40, 10:50

Step-by-step explanation:

When I first tried this I thought it was for every one there was fifteen. I messed up then looked, realized, and changed it. For every 3 there is 15 so 15 ÷ 3 = 5 so when I saw the 5 I multiplied it by five to get 25 then continued throughout. Your first step when doing these problems again is to divide (but make sure you divide the right number) then once you find out that sweet number, multiply is by the time to get the photos, and divide by five on the photos to get the time.

<em>Hope you got this right!</em>

Principal Philippi use a random sample of 20 student records to determine how far in miles students live from the school the res
nexus9112 [7]

Take 3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together

=83

Now you divide 83 by the number of terms in the sample set, which is 20.  

83/20 = 4.15

For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.  

final answer= 4.2

The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew
Nadusha1986 [10]

Answer:

Terry initially had £390

Step-by-step explanation:

The ratio of the original amount is 3:7

Let the original amount Terry has be t and the original amount Faye has be f

3/7 = t/f

or simply 3f = 7t ••••••(i)

Terry putting 220 means he now has

t + 220

Faye withdrew 300

He now has f-300

These values are equal

t + 220 = f-300

f = t+220+300

f = t + 520 ••••••(ii)

Put ii into i

3(t + 520) = 7t

3t + 1560 = 7t

7t-3t = 1560

4t = 1560

t = 1560/4

t = 390

If m angle acd = 120- x, m angle b = 60, and m angle a = 10 + x, find m angle acb
lesya [120]

Answer:

ACB = 85

Step-by-step explanation:

First find x:

10+ x + 60 = 120 - x

x + 70 = 120 - x

Add x to both sides

2x + 70 = 120

subtract 70 from 120

2x = 50

Divide 2 from both sides

x = 25

10 + 25 + 60 = 95

Subtract 95 from 180

ACD = 85
