Answer:
4
Step-by-step explanation:
First off, integers are Whole Numbers (1,2,3,4, etc), so we are rounding the answer to the nearest whole number.
The square root of lets just say 25 means you are finding a number that multiplied by itself will equal 25 (the answer is 5).
Now for 13, there is no perfect square, however the closest whole number that multiplied by itself to 13 is 4.
4*4= 16
3*3=9
5*5=25
As you can see above 4 is the closest number to 13.
Now, the ACTUAL value of the square root of 13 is 3.60555128, but we are rounding up to the nearest whole number which is 4 :)
The square root of 13 is approximately 3.6055, but to the nearest integer (whole number), it's 4.
Explanation:The question asks for the square root of 13. First, it's important to understand what a square root is. In simple terms, the square root of a number is a value that, when multiplied by itself, gives the original number. So, if you take the square root of 16, for example, it's 4 because 4 multiplied by 4 equals to 16. Now, 13 is not a perfect square, so its square root is not a whole number. If you calculate the square root of 13, you'll get an answer somewhere around 3.6055. However, the question asks for the nearest integer. An integer is a whole number, so we're looking for the whole number closest to 3.6055. In this case, it's 4. So, the square root of 13, to the nearest integer, is 4.

Does anyone know how to solve this?
Answer:
That is a quadratic equation.
It can be solved by using the quadratic formula:
x = (-b +-sqr root b^2 -4*a*c) / 2 *a
In this equation a = -3
b = -4 and c = -8
x = (--4 +- sqr root (-4^2 - 4 * -3 * -8)) / (2 * -3)
x = (4 +- sqr root (16 -96)) / -6
x = 4 +- sqr root (-80) / -6
x1 = (4 +8.94427191 * i) / -6
x2 =(4 -8.94427191 * i) / -6
Remember that "i" is the square root of minus 1.
Step-by-step explanation:
Find the solution of the system of equations.
–8x + 15y = –28
2x + 5y = -28
Step-by-step explanation:
To solve this system of equations, you can use either substitution or elimination. Let's use the elimination method.
First, multiply the second equation by 4 to make the coefficients of \( x \) in both equations opposites:
\( (2x + 5y) \times 4 = -28 \times 4 \)
This gives us:
\( 8x + 20y = -112 \)
Now, we'll subtract the first equation from this modified second equation:
\( (8x + 20y) - (-8x + 15y) = -112 - (-28) \)
Simplify:
\( 8x + 20y + 8x - 15y = -112 + 28 \)
\( 16x + 5y = -84 \)
Now we have a new equation:
\( 16x + 5y = -84 \)
And the first equation remains the same:
\( -8x + 15y = -28 \)
Now, we can solve this system of equations by elimination or substitution. Let's continue with elimination. Multiply the first equation by 2:
\( -16x + 30y = -56 \)
Now, add this equation to the second modified equation:
\( (-16x + 30y) + (16x + 5y) = -56 - 84 \)
\( 30y + 5y = -140 \)
\( 35y = -140 \)
Divide both sides by 35:
\( y = -4 \)
Now, substitute \( y = -4 \) into one of the original equations to solve for \( x \). Let's use the first equation:
\( -8x + 15(-4) = -28 \)
\( -8x - 60 = -28 \)
Add 60 to both sides:
\( -8x = -28 + 60 \)
\( -8x = 32 \)
Divide both sides by -8:
\( x = -4 \)
So, the solution to the system of equations is \( x = -4 \) and \( y = -4 \).
on the first day of the clothing drive 11 rain jackets were collected at the end of the drive 10 times that number of rain jackets were collected how many rain jackets were collected
Answer:
There were 121 rain jacket were collected
Step-by-step explanation:
* Lets explain how to solve the problem
- On the first day of the clothing drive, 11 rain jackets were collected
- At the end of the drive 10 times that number of rain jackets were
collected
- We want to find how many rain jackets were collected
∵ There were 11 rain jacket were collected on the first day
∵ Ten times that number were collected at the end of the drive
- Ten times means we will multiply the number of rain jacket in
the first day of the clothing drive by 10
∴ The number of rain jacket at the end of the drive = 10 × 11 = 110
∴ There were at the end of the drive 110 jackets
- To find the number of the rain jacket were collected is the sum
of the number of rain jacket at the first day and at the end of
the drive
∴ The number of rain jacket = 110 + 11 = 121
* There were 121 rain jacket were collected

Rate as Brainliest plz
Answer:
A. x<7
Step-by-step explanation:
We know three things:
The facility takes 4 cats per dayThe facility has to keep the occupancy below 200Currently, the facility has 172 catsNow we want to know how many more days the facility can continue to take in cats if none of their cats get adopted.
First, we want to know how many cats until the facility exceeds the occupancy and to do it we have to subtract the occupancy minus the cats they already have:
200 - 172 = 28
With this answer, we know that if they get 28 more cats they will have 200 cats and the occupancy has to be below 200.
Now we want to know how many days will it take them to get 28 more cats:
We know that every day they get 4 cats, so we are going to divide the number of cats to get 200 by the number of cats they get every day:
28(cats) / 4(cats per day) = 7 days
So in 7 days, they will pass their occupancy, which means that they can only take cats less than 7 days.
The expression will be:
x < 7
Where:
x is how many more days they can take in cats
< means less than
You measure the shadow cast by a certain tall building and find that it is 105 feet long. Then you measure the shadow by a three foot post and find that is 4 inches long. Determine the buildings height
The height of the building is 315 feet because the ratio of the building's height to the post's height is equal to the ratio of the building's shadow length to the post's shadow length.
How to find height?This problem can be solved using the concept of proportionality.
The height of the building is proportional to the length of its shadow, and the height of the post is proportional to the length of its shadow.
Express this mathematically as follows:
Building height / Post height = Shadow length / Post shadow length
Substituting the known values:
Building height / 3 feet = 105 feet / 4 inches
Convert 105 feet to inches first. 105 feet is equal to 105 × 12 = 1260 inches.
Rewrite the equation as follows:
Building height / 3 feet = 1260 inches / 4 inches
The units cancel out, and are left with:
Building height = 1260 / 4 = 315 feet
Therefore, the height of the building is 315 feet.

Final answer:
To calculate the building's height, we set up a proportion using similar triangles. With the shadow of the building being 105 feet and the shadow of a 3-foot post being 4 inches (1/3 feet), we solve the proportion to find that the building is 315 feet tall.
Explanation:
To determine the height of the building, we can use similar triangles. The method involves setting up a proportion based on the principle that similar triangles have corresponding sides that are in the same ratio. Given the length of the building's shadow and the length of the shadow cast by a known post, we can find the building's height.
Let's define the following variables: B for the height of the building, Sb for the length of the building's shadow, P for the height of the post, and Sp for the length of the post's shadow. From the problem, Sb = 105 feet, P = 3 feet, and Sp = 4 inches, which is 1/3 feet since there are 12 inches in a foot.
Using these variables, the proportion can be set up as follows:
B/Sb = P/SpPlugging in the known values, we get:
B/105 = 3/(1/3)By solving this proportion for B, we find that:
B = (3 × 105) × 3B = 315 feetTherefore, the height of the building is 315 feet.

How do you solvs q/r-6=q for r?
Answer:
r = q -6
Step-by-step explanation:
q= [tex]\frac{q}{r} -6[/tex]
[tex]\frac{\frac{q}{r} -6}{r}[/tex]
You do kcf (keep it, change it, flip it)
[tex]\frac{q}{r} -6 times \frac{r}{1}[/tex]
To solve the equation q/r - 6 = q for r, you need to isolate the variable r on one side of the equation.
Explanation:To solve the equation q/r - 6 = q for r, we need to isolate the variable r on one side of the equation. First, we'll get rid of the fraction by multiplying both sides of the equation by r. This gives us r(q/r) - 6r = qr. Simplifying further, we have q - 6r = qr. Next, we'll move all the terms involving r to one side by subtracting qr from both sides of the equation. This gives us q - qr - 6r = 0. Factoring out the common factor of r from the last two terms, we have q - r(q + 6) = 0. Finally, we solve for r by dividing both sides of the equation by q + 6. So, the solution to the equation is r = q/(q + 6).
