The actual pressure before the percentage increase is 36.5

<h3>How to calculate the Actual pressure?</h3><h3 />

New pressure = £39.42
Percentage increase = 8%

let

x = actual pressure

39.42 = x + (8% of x)

39.42 = x + (0.08x)

39.42 = 1.08x

x = 39.42 ÷ 1.08

x = 36.5

Therefore, the actual pressure before the percentage increase is 36.5

5/8 - 3/10 <br> A. 13/40 <br> B. 1/20 <br> C. 1/4<br> D. 1/5

densk [106]

5/8 - 3/10

Find the common denominator:

Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)

Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)

5/8 = 5*5 / 8*5 = 25/40

3/10 = 3*4 / 10 *4 = 12/40

Now you have 25/40 - 12/40

25 -12 = 13

Answer = 13/40

The answer is A.

WILL GIVE BRANLIEST! pls help thank u sm!! :-) u are all amazing

Andrews [41]

Answer:

Step-by-step explanation:

Given

3 $(x+9)^{\frac{3}{4} }$ = 24 ( divide both sides by 3 )

$(x+9)^{\frac{3}{4} }$ = 8

Raise both sides to the power of $\frac{4}{3}$

x + 9 = $8^{\frac{4}{3} }$ = $(\sqrt[3]{8}) ^{4}$ = $2^{4}$ = 16 ( subtract 9 from both sides )

x = 7 → C

What are the apparent zeros of the cubic function graphed above? (also if you have the answers to the rest of this test plz send

Mazyrski [523]

<em>The point where a function (for our problem its the cubic function shown)</em>

cuts/crosses the x-axis

touches the x-axis

<em>is a zero of the function.</em>

From the graph shown, we can clearly see that it cuts the x-axis at -1 and touches the x-axis at 2.

So the zeros are at -1 and 2.

The capacity of an elevator is 12 people or 2088 pounds. the capacity will be exceeded if 12 people have weights with a mean gre

boyakko [2]

suppose the people have weights that are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.

Find the probability that if a person is randomly selected, his weight will be greater than 174 pounds?

Assume that weights of people are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.

Mean = 177

standard deviation = 26

We find z-score using given mean and standard deviation

z = $\frac{x-mean}{standard deviation}$

= $\frac{174-177}{26}$

=-0.11538

Probability (z>-0.11538) = 1 - 0.4562 (use normal distribution table)

= 0.5438

P(weight will be greater than 174 lb) = 0.5438
