16. At the same time a 10-foot pole casts a 22-foot shadow,

Hatshy [7]

The answer is 32

Solution for 40 is what percent of 125:

40:125*100 =

( 40*100):125 =

4000:125 = 32

Now we have: 40 is what percent of 125 = 32

Question: 40 is what percent of 125?

Percentage solution with steps:

Step 1: We make the assumption that 125 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=125$100%=125.

Step 4: In the same vein, $x\%=40$x%=40.

Step 5: This gives us a pair of simple equations:

$100\%=125(1)$100%=125(1).

$x\%=40(2)$x%=40(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{125}{40}$
100%
x%=
125
40

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{40}{125}$
x%
100%=
40
125

$\Rightarrow x=32\%$⇒x=32%

Therefore, $40$40 is $32\%$32% of $125$125.

Firdaus measured the length of the wall and got 9 feet her cousin measured the same distance and said that it was three what uni

Dahasolnce [82]

Answer:

Her cousin used Yard to measure the wall.

Step-by-step explanation:

Firdaus measured the length of the wall and got 9 feet.

Her cousin measured the same distance and said that it was 3.

To find the answer, we have to use division.

Let "x" the divisor which divide 9 and gives the answer 3.

9 ÷ x = 3

3x = 9

To find x (divisor) we need to divide both sides by 3, we get

3x ÷ 3 = 9 ÷ 3

x = 3

So 1 unit cousin's measure = 3 feet Firdaus measure

We know that 1 yard = 3 feet.

Therefore, her cousin used Yard measure to measure the wall.

The probability that a lab specimen contains high levels of contamination is 0.14. A group of 4 independent samples are checked.

Shtirlitz [24]

Answer:

a) 0.5470 = 54.70% probability that none contain high levels of contamination.

b) 0.3562 = 35.62% probability that exactly one contains high levels of contamination.

c) 0.4530 = 45.30% probability that at least one contains high levels of contamination.

Step-by-step explanation:

For each sample, there are only two possible outcomes. Either they contain high levels of contamination, or they do not. The samples are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
