(S1 + S2+ S3)L + bh

(17 + 15+ 8)25 + 15*8

40*25+120

You first have to multiply the -5.3 times the -1.9. Once you do that, you get 10.07. Then, you add the -7.5.

Here are the equation steps:

(-7.5) + (-5.3)x(-1.9)

(-7.5) + (10.07)

In a bolt factory, machines 1,2, and 3 respectively produce 20%, 30% and 50% of the total output. of their respective outputs 5%

lorasvet [3.4K]

Answer:

a. 1/10 or 10%

b. 1/2 or 50%

Step-by-step explanation:

Since the combination of machines 1, 2 and 3 produce 100% of the total output when added together, then the probability of choosing a bolt at random that is defective is: 5 + 2 + 3 = 10% out of 100% or 10/100, which is 1/10 or 10%.

If the bolt that is choosen at random is defective, than the probability that it came from machine 1 is 5/10 or 1/2 which is also 50%.

Spotlight Dance increased the number of dancers on its competition team. Last

Nana76 [90]

Answer:

80%

Step-by-step explanation:

To find percentage increase, we use the following formula:

Percentage Increase = $\frac{New-Old}{Old}*100$

Here

New means the latest value (which is 18 dancers)

Old means the previous value (which is 10 dancers)

The Multiplication by 100 is to convert the decimal answer to percentage.

So, we have:

New = 18

Old = 10

Now we substitute and find:

$\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80$

So, there was an increase of 80%

Help due now pleaseee

DENIUS [597]

Answer:

Step-by-step explanation:

base² + Altitude² = Hypotenuse²

x² + 9² = 13²

x² + 81 = 169

x² = 169 - 81

x² = 88

x = $\sqrt{88}$

$x = \sqrt{2*2*2*11}=2\sqrt{2*11}\\\\x=2\sqrt{22}$
