Answer:

30

Step-by-step explanation:

40% of 75

40/100 = x/75

Cross Multiply

40(75) = 100x

3000 = 100x

Divide by 100 on both sides

x = 30

Hope this helps :)

In the first year of a 10,000 investment the interest rate was 6%. All earned interest remained invested for the second year, an
Aleks04 [339]

Answer:

13.4%

Step-by-step explanation:

First year:

$10,000*6% = $600

New balance = $10,600

Second Year:

$10,600*7% = $742

$10,600+ $742 = $11,342

Total Return:

Final Balance - Initial balance

$11,342 - $10,000 = $1,342

$10,000*x ÷ $1,342

x = $1,342/$10,000

x = 0.1342

0.134 = 13.4%

10. The perimeter of a triangle is 48'. The sides are in the ratio of 1 to 2 to 3. Find the three sides.​
pentagon [3]

Answer:

Step-by-step explanation:

The sides are in the ratio 1:2:3, so the lengths of the sides are 1x, 2x, 3x.

1x + 2x + 3x  = 48'

6x = 48'

x = 8'

The lengths of the sides are 8', 16', 24'

Help me solve # 15 & 16
makkiz [27]

Answer:

15) C=frac{5}{9}(F-32)

16) 12 hours

Step-by-step explanation:

15) F=\frac{9}{5}C+32 \\F-32 = \frac{9}{5}C\\\frac{5}{9}(F-32)=C

16) If Jim drove 168 mi in 4 hours, this means it takes him

\frac{4 hours }{168 mi}

this many hours to drive 1 mile. So if we multiply this by 504 mi:

\frac{4 hours }{168 mi} 504 mi = 4 \cdot 3 hours = 12 hours

In triangle ABC, the side lengths are AB = 13, AC = 21, and BC = x. Write a compound inequality that represents the range of pos
N76 [4]

There is only 1 solution for the length of BC.

We can calculate it using Pythagorean theorem.

We can conclude that triangle's hypotenuse is AC.

AC^2=AB^2+BC^2

If that is the case we are looking for a side BC.

BC=\sqrt{AC^2-AB^2}

Now put in the data.

BC=\sqrt{21^2-13^2}=\sqrt{272}=\sqrt{272}\approx\boxed{16.49}

Hope this helps.
