8 x 10 = 80 inches squared (one side)
3 x 8 = 24 inches squared (one side)
3 x 10 = 30 inches squared (one side)
80 + 24 + 30 = 134 inches squared (three sides)
Double that for all 6 sides. 2 x 134 = 268 square inches.
The answer is D.

SA = </span></span>2<span>(<span><span><span>(3)(10)</span>+<span>(8)(10)</span></span>+<span>(8)(3)</span></span><span>)

Multiply:

SA = 2(30 + 80 + 24)

Add:

SA = 2(134)

Multiply:

SA = 268</span></span>

A shop has this offer.

49x3= 147 so 10 reduction will make tim spend 137. 49x5= 245 so 20 reduction will make Craig spend 225. 225-147= 78 so Craig spends 78£ more than tim. All the offers state “X or Y” meaning it’s one or the other hence the ‘or’. Atleast that’s my interpretation of it.

1) Last Tuesday, Regal Cinemas sold a total of 85 movie tickets. Ticket sales totaled
irakobra [83]

In this question, some of the data is missing so its a complete question and the solution can be defined as follows:

\bold{\text{m = matinee tickets}} \\\\\bold{\text{s = student tickets}}\\\\\bold{\text{r = regular tickets}}

By given question, calculating equations are:

\to \bold{m + s + r = 8500}............................................(a)\\\\\to \bold{5m + 6s + 8.50r = 64600}............................(b)\\\\\to \bold{s = 2m}...................(c)

Putting the equation (c) value in the equation (a) to calculate value:

m + 2m + r = 8500\\\\3m + r = 8500\\\\r = 8500 - 3m........................................(d)

Putting equation (c) and (d) value into equation (b):

5m + 6(2m) + 8.50(8500 - 3m) = 64600\\\\5m + 12m + 72250 - 25.50m = 64600\\\\-8.50m = 64600 - 72250 \\\\-8.50m = -7650\\\\m = \frac{-7650}{-8.50}\\\\m = \frac{7650}{8.50}\\\\m = 900

Putting m value into equation (c) and equation (d) to calculate its value:

Calculating the s value:

\to s = 2(900) \\\\ \to s = 1800

Calculating the r value:

\to r = 8500 - 3(900) \\\\\to r = 8500 - 2700\\\\\to r = 5800\\\\

So, the final value of "m, s, and r" are "900, 1800, and 5800".

Can you please help me solve this?
oee [108]
So, i would use the add the two equation method, so add those to get:
2e=-4
e=-2
then plug in e to get d, so d+-2=1
d=3
plug into the other one to make sure
-3+-2=-5
so it would be (3,-2)

The hawk population in a county is declining at a rate of 1.4% per year. the population was 3800 in the year 2016. which answer
Anika [276]

After a year the population will be 98.6% (100% - 1.4%) 98.6% as a decimal is 0.986 ... so after 1 year it will be: <span>

3800 x 0.986 

after 2 years it will be: 

3800 x 0.986 x 0.986... 

after 3 years: 3800 x (0.986)^3 

<span>in 2018. And after 4 years it will be 3800 x (0.986)^4 = which is 3591.62724 or 3592</span></span>
