150 because 6 times 5 is 30 then you multiply whats inside the square root thing so you'd get 25, 25 is a perfect square which simplifies to 5 then 5 times 30 is 150.

puteri [66]

<h3>Total cost for Neil degree is $ 4980 </h3>

<em><u>Solution:</u></em>

Given that,

Neil decides to go to a technical college for 18 months to get a degree in computer networking

Number of months = 18 months

There are 6 school quarters in the program with a tuition of $530 each

Thus there are 6 quarters

For one quarter, tuition fee is $ 530

For 6 school quarters, tuition fee is given

$\rightarrow 6 \times 530 = 3180$

Books for the entire program cost $1800

Total cost for degree = tuition cost + books cost

Total cost for degree = 3180 + 1800

Total cost for degree = 4980

Thus total cost for Neil degree is $ 4980

MAVERICK [17]

Answer:

See below.

Step-by-step explanation:

If the original price is $p then final price is calculated as follows:

We start with p - 5 because the coupon was applied before the discount.

Final price = $( p - 5 ) - 0.2(p - 5)

= p - 5 - 0.2p + 1

= $(0.8p - 4).

uysha [10]

Step-by-step explanation:

step 1. 2x + 3x + 4x = 180° internal triangle angles add up to 180°

step 2. 9x = 180 or x = 20

step 3. <A = 2x = 2(20) = 40°

step 4. <B = 3x = 3(20) = 60°

step 5. <C = 4x = 4(20) = 80°.

What is one half added to seven tenths

Ivahew [28]

1. You need to change these so that they share a common denominator (bottom of the fraction)
2. Common denominator is 10 of these 2 fractions.
3. We don't need to change the 7/10 fraction because the denominator is already 10.
4. To make 1/2 have a denominator of 10, we need to times the top and bottom by the same number. To get 10 from 2, we have to times it by 5. Therefore, to change the top, we need to times it also by 5
5. 1 x 5 = 5
6. Add the two fractions together: 5/10 + 7/10 = 12/10
7. Simplify the expression. This is currently a top heavy fraction aka. improper fraction. To make it 'proper' we need to change it into a mixed number. To do this, we see how many of the bottom number goes into the top. In this case it is 1 with 2 left over. So the final fraction is...

1 2/10
Hope this helps :)
