975 ÷7.5 = 130 cu ft
2130 - 130 = 2000
2000 ÷ 20 = 100 min

If the total volume is 2130 cubic feet, if you convert that to gallons its 15975 gallons, it already has 975 so subtract. you need to fill 15,000 gallons. you can do 20 cubic feet per minute which is 150 gallons. 15000/150 = 100minutes

What does the C equal to in -1/6 +7/6 = c

STALIN [3.7K]

Answer:

c = 1

Step-by-step explanation:

we have -1/6 + 7/6

since 6 is a common denominator we can do

$\frac{-1}{6} +\frac{7}{6} = c\\\frac{-1+7}{6} = c\\\frac{6}{6} = c\\1 = c\\c = 1$

nataly862011 [7]

Question:

A research center poll showed that 78% of people believe that it is morally wrong to not report all income on tax returns. What is the probability that someone does not have this belief?

The probability that someone does not believe that it is morally wrong to not report all income on tax returns is . (Type an integer or a decimal.)

Answer:

$q = 0.22$

Step-by-step explanation:

Given

Let p represent the given proportion

p = 78%

Required

Determine the probability that someone holds a contrary belief

Start by converting the given proportion to decimal

$p = 78\%$

$p = \frac{78}{100}$

$p = 0.78$

In probability, the sum of opposite probability is equal to 1

Represent the probability that someone holds a contrary belief with q

So;

$p + q = 1$

Make q the subject of formula

$q = 1 - p$

Substitute 0.78 for p

$q = 1 - 0.78$

$q = 0.22$

Hence, the probability that someone does not believe is 0.22

A land developer is splitting up 1.19 hectares of land to form 9 identical properties. To the nearest tenth of a hectare, what s

OlgaM077 [116]

In this question , it is given that the land is 1.19 hectares. And the land developer splitting it into 9 identical properties . So to find the size of each property, we need to divide 1.19 by 9 and on doing that, we will get 0.13 hectares .

So the size of each property is 0.13 hectares .

Angle APR is vertical with Angle SPL. If Angle APR = 13x - 30, and Angle SPL = 3x + 70, what is the value of x?

Luba_88 [7]

Answer:

The value of $x$ is 10.

Step-by-step explanation:

If APR and SPL are vertical angles, then we get that $\angle APR = \angle SPL$ . Given that $\angle APR = 13\cdot x -30$ and $\angle SPL = 3\cdot x + 70$ , we find that the value of $x$ is:

$13\cdot x - 30 = 3\cdot x +70$

$10\cdot x = 100$

$x = 10$

The value of $x$ is 10.

(-1,-2) would result in a relation that is no longer a function.

In the table, there's already x = -1 and y = -4. Function only gives a single y-value with x-value. If a single x-value gives two y-values then it'd not be Function.

If we add (-1,-2) in the table. The domain will be repetitive. Basically, we already have (-1,-4) and if we add (-1,-2) in the table, a single x-value will give TWO y-values which is not a function.
