<span>In order to calculate how long it will take Jamie to finish painting the fence, you should divide the length of the fence by the rate at which Jamie paints. Thus, if the fence is 119.5 yards long and Jamie paints on average 4.78 yards per hour, we divide 119.5 by 4.78 and get the answer - 25 hours. We can double check our work by multiplying Jamie's painting rate by the time, so if Jamie paints 4.78 yards per hour for 25 hours, he will paint all 119.5 yards.</span>

A water tank leaks 5 gallons of water each day. What integer represents the change in the number of gallons of water in the tank
andrey2020 [161]

Answer:

35 is the integer that represents the change in number of gallons of water in the tank after 7 days

Step-by-step explanation:

The water tank leaks 5 gallons in one day.

So if there is leakage of 5 gallons a day, then after 7 days the total leakage will be:

Total Leakage = Leakage per day * Total number of days

= 5 Gal/day * 7 day

= 35 Gallons

So, 35 is the integer that represents the change in number of gallons of water in the tank after 7 days ..

Find the value of x in each case:
Zanzabum

Answer:

x=30\°

Step-by-step explanation:

<u>Find the measures of interior angles in each triangle</u>

Triangle BGC

m

The measures of triangle BGC are 90\°-60\°-30\°

Triangle CGH

we know that

m -----> by consecutive interior angles

we have that

m

so

m

m

substitute

m

we have

m

m

m

remember that

m

60\°+2x+180\°-4x=180\°

60\°=2x

x=30\°

The measures of triangle CGH are 60\°-60\°-60\°

Triangle GHE

m< EGH=90\°-2x=90-2(30\°)=30\°

m< GHE=4x=4(30\°)=120\°

remember that

m

substitute and solve for m<GEH

30\°+120\°+m

150\°+m

m

The measures of triangle GHE are 30\°-120\°-30\°

Which is the simplified form of x Superscript negative 12?
chubhunter [2.5K]

Answer:

C.\frac{1}{x^{12}}

Step-by-step explanation:

We are given that an expression

(x)^{-12}

We have to find the simplified form of given expression.

We know that

a^{-b}=\frac{1}{a^b}

Using the property then we get

x^{-12}=\frac{1}{x^{12}}

Hence, the simplified form of x^{-12} is given by

\frac{1}{x^{12}}

Option C is true.

kvasek [131]

Answer:

(a) 0.932

(b) 0.0653

(c) 0.032

(d) 0.316

(e) 0.251

Step-by-step explanation:

From the table with mean parameter μ = 5, we can compute the following cumulative and density probability

(a) P(X \leq 8) = 0.932 (cumulative)

(b) P(X = 8) = 0.0653 (density)

(c) P(9 \leq X) = 1 - P(X \leq 9) = 1 - 0.968 = 0.032 (cumulative)

(d) P(5 \leq X \leq 8) = P(X \leq 8) - P(X \leq 5) = 0.932 - 0.616 = 0.316 (cumulative)

(e) P(5 < X < 8) = P(X \leq 8) - P(X \leq 5) - P(X = 8) = 0.932 - 0.616 - 0.0653 = 0.251
