The total amount of paint needed is 15 quart and it cost $41.25.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
0.0015 quart of paint to cover 1 square inch.
Let the area of the rectangle be 10000 in², hence:
Amount of paint = 0.0015 quart per in² * 1000 in² = 15 quart
Cost of paint = $2.75 per quart * 15 quart = $41.25
The total amount of paint needed is 15 quart and it cost $41.25.

∠A and \angle B∠B are supplementary angles. If m\angle A=(2x+26)^{\circ}∠A=(2x+26)
∘
and m\angle B=(x+25)^{\circ}∠B=(x+25)
∘
, then find the measure of \angle B∠B
we know angles A and B are supplementary, thus their sum is 180°.
[tex]\stackrel{\measuredangle A}{(2x+26)}~~ + ~~\stackrel{\measuredangle B}{(x+25)}~~ = ~~180\implies 3x+51=180\implies 3x=129\\\\\\x=\cfrac{129}{3}\implies x=43~\hspace{10em}\stackrel{\measuredangle B = 43 + 25}{68}[/tex]
The measure of angle m∠B = 112°
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.
Supplementary angles have a sum of 180°
Therefore, we can add the expressions for Angles A and B and set their sum equal to 180.
( 2x+26 ) + ( x+25 ) = 180
Now we can combine like terms and apply the operations to find the value of x:
⇒ ( 2x+26 ) + ( x+25 ) = 180
⇒ 3x + 51 = 180
⇒ 3x = 180 - 51
⇒ 3x = 129
⇒ x = 129/3
⇒ x = 43
Then Angle B will have a measure of x+25 = 43 + 25 = 68°
m∠ B = 112°
The measure of Angle A will be :2x+26 = 2(43) + 26 = 112°
m∠A = 68°
Thus, the measure of angle m∠B = 112°

Given:
A phrase: 360 divided by 9.
To find the quotient:
360 divided by 9;
360 ÷ 9,
Here,
The factors of 360 = 2 x 3 x 3 x 3 x 3 x 5
And the factors of 9 = 3 x 3.
The GCF of 360 and 9 is 9.
So, the quotient will be a whole number.

Write a numerical expression that represents the area Sabrina painted the second weekend. Using this numerical expression, find the area that Sabrina painted the second weekend.
Step-by-step explanation:
she painted half of the still to be painted area.
after the first weekend there were 800 of 1600 ft² painted, and therefore 1600 - 800 = 800 ft² left to be painted.
on the second weekend she then painted half of that :
800 / 2.
that means she painted 800/2 = 400 ft², and that left 800 - 400 = 400 ft² to be painted on the following weekends.
if we look in detail, we find the starting 800 ft² of the second weekend are already the result of the first weekend.
800 = 1600 / 2
so,
800 / 2 = 1600 / 2 / 2 = 1600 / 2² = 1600 / 4.
and the same principle goes on weekend after weekend.
therefore, the expression for the nth weekend could be
1600 × (1/2)^n ft²
that means, she painted
on the 1st weekend : 1600 × 1/2 = 800 ft²
on the 2nd weekend : 1600 × 1/4 = 400 ft²
on the 3rd weekend : 1600 × 1/8 = 200 ft²
on the 4th weekend : 1600 × 1/16 = 100 ft²
...
that also means : she will never be finished, as she always paints only half of what is still left open, and that leaves always some part open. it will be tinier and tinier over time, but never 0.

The number of penguins on an iceberg is
modeled by the equation P(t) = 24(1.231)^t
where t is years since 2010. If
the iceberg has a population of 70 penguins it
will begin to sink and the penguins will have to
find a new home. In
what year are the penguins going to find a new home?
The function of the number of penguins is an exponential function
The penguins are going to find a new home in 2015
How to determine the yearThe equation of the function is given as:
[tex]P(t) = 24(1.231)^t[/tex]
When there are 70 penguins, the equation becomes
[tex]24(1.231)^t =70[/tex]
Divide both sides by 24
[tex]1.231^t =2.917[/tex]
Take the logarithm of both sides
[tex]t\log(1.231) =\log(2.917)[/tex]
Divide both sides by log(1.231)
[tex]t =5[/tex]
The time is 5 years from 2010.
So, we have
Year = 2010 + 5
Year = 2015
Hence, the penguins are going to find a new home in 2015

If the length of the side of a square is 11cm. Then find its area and also find the total length of its boundary.
Answer:
[tex]\displaystyle 44\:cm. = P \\ 121\:cm.^2 = A[/tex]
Step-by-step explanation:
All angles and edges are congruent in a square, so first, find the total boundary by multiplying the length of the edge by 4:
[tex]\displaystyle 4l = P \\ 4[11] = P \\ \\ 44 = P[/tex]
Now, for the area, you square the length of the edge:

There were 324 adults surveyed. Among the participants, the mean number of hours of sleep each night was 7. 5 and the standard deviation was 1. 6. The margin of error, assuming a 95% confidence level, is approximately. Round to the nearest hundredth.
The margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.
What is the margin of error?The margin of error can be defined as the amount of random sampling error in the results of a survey. It is given by the formula,
[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\frac{\sigma^{2}}{n}}[/tex]
[tex]\text{MOE}[/tex] = margin of error
[tex]\gamma[/tex] = confidence level
[tex]z_{\gamma}[/tex] = quantile
σ = standard deviation
n = sample size
As it is given that the sample size of the survey is 324, while the standard deviation of the survey is 1.6.
We know that the value of the z for 95% confidence interval is 1.96. Therefore, using the formula of the standard of error we can write it as,
[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\dfrac{\sigma^{2}}{n}}\\\\\text{MOE}_{\gamma}=1.96 \times \sqrt{\dfrac{1.6^{2}}{324}}\\\\\text{MOE}_{\gamma}=0.1742[/tex]
Hence, the margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.
