Hey there!
The perimeter of the floor plan is 30 inches.
Perimeter is length + length + width + width, so we can do 9 + 9 + 6 + 6 = 30
The area of the floor plan is 54 inches²
Area is length x width, so we can do 9 x 6 = 54
The perimeter of the actual size is 105 feet
First, we can solve the dimensions for the actual size. We know that 2 inches = 7 feet, so we can do 7/2 and get 3.5. This means that for every 1 inch, it's 3.5 feet. Then, we multiply the dimensions by 3.5:
9 x 3.5 = 31.5 feet
6 x 3.5 = 21 feet
Then we solve for perimeter. Perimeter is length + length + width + width, so we can do 31.5 + 31.5 + 21 + 21 = 105
The area of the actual size is 661.5 inches²
Area is length x width, so we can do 31.5 x 21 = 661.5
Hope this helps! Tell me if you need more help.
Pls help me. It due ASAP...

Consider this quadratic equation:
2x2+1x+3=0
Comparing it to the standard form, name a, b, and c
a=
b=
C=
Explanation: The value for a comes from the coefficient
on the x² term which in this case is 2 so we say that a = 2.
The value for b comes from the coefficient on the x term
which in this case is 1 so we say that b = 1.
The value for c comes from the constant term
which in this case is 3 so we say that c = 3.

6. Determine the Rate of Change in the graph below.
Answer: slope is 1/2
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
Using the equation slope = y2-y1/x2-x1 we can plug in (-4,-6) as x1 and y1 and (6,-1) as x2 and y2. We than have the equation -1+6/6+4 = slope, doing the math we now have 5/10 or 1/2 which is our rate of change
hi can someone please help me
Answer:
Volume = 1436.8 cm³
Step-by-step explanation:
Formula for the volume of a sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]
Here, r = radius of the sphere
For a sphere which has the radius = 7 cm
Volume of the sphere = [tex]\frac{4}{3}\pi (7)^3[/tex]
= 1436.76
≈ 1436.8 cm³
Therefore, volume of the sphere is 1436.8 cm³.
Jeremy is plotting a line with a slope of 3. He starts by plotting the point (-4,-3). He then plots a second point on the line 6 units to the right, and k units up. His value of k must be a. 9 b. 18 c. 2 d. 24
Answer:
27
Step-by-step explanation:
Slope = 3
(-4, - 3) (6, k)
(y2 - y1) /(x2 - x1) = 3
(k + 3) / (6 + 4) = 3
(k +3) / 10 = 3
k + 3 = 30
k = 30 - 3
k = 27
Emma needs 2 pounds of ground meat to make a meatloaf. She goes to Brodies and finds one package of meatloaf with 2.56 pounds and another package with 2.09 pounds. She uses rounding to the nearest whole. Which package should she choose to get closer to 2 pounds? Explain.
Answer:
package with 2.09 pounds
Step-by-step explanation:
When rounding to the nearest whole number, if the first number after the decimal point is equal or greater than 5, add 1 to the number before the decimal. If this is not the case, add 0 to the number before the decimal point.
to round 2.56 to the nearest whole number equals 3.
While to round 2.09 to the nearest whole number equals 2.
Because Emma needs 2 pounds, she would go with 2.09 pounds
at basketball camp kylie made 18% of her free throws based on this information which is the best prediction of the number of free throws she will make out of 50 attempts
Answer:
Number of free throws = 9
Step-by-step explanation:
Given that:
Kylie made 18% of her free throws.
Number of attempts = 50
Based on the information, she will make out 18% free throws.
Number of free throws = 18% of 50
Number of free throws = [tex]\frac{18}{100}*50[/tex]
Number of free throws = 0.18 * 50
Number of free throws = 9
Hence,
Number of free throws = 9

Find x and y so the quadrilateral is a parallelogram.
Answer:
Summary:
The value of x = 7 The value of y = 4Step-by-step explanation:
We know that the diagonals of a parallelogram bisect each other.
As
The parallelogram PQRS is given, so
RT = TP
Given
RT = xTP = 5x-28plug in RT = x and TP = 5x-28 in the equation RT = TP
RT = TP
x = 5x-28
switch the sides
5x-28 = x
adding 28 in both sides
5x-28+28 = x+28
simplify
5x = x+28
subtract x from both sides
5x-x = x+28-x
4x = 28
divide boh sides by 4
4x ÷ 4 = 28 ÷ 4
simplify
x = 7
Therefore, we conclude that the value of x is: x = 7
Similarly,
QT = TS
Given
QT = 5yTS = 2y+12plug in QT = 5y and TS = 2y+12 in the equation QT = TS
QT = TS
5y = 2y+12
subtract 2y from both sides
5y - 2y = 2y+12-2y
simplify
3y = 12
divide both sides by 3
3y ÷ 3 = 12 ÷ 3
simplify
y = 4
Therefore, we conclude that the value of y is: y = 7
Summary:
The value of x = 7 The value of y = 4Do this for a lot of points and brainly!!! Asap

Write the equation of a line parallel to the line y = 2x that passes through 0,4
Note: this answer assumes that the question accepts the equation to be written in slope-intercept form.
Answer:
y = 2x + 4
Step-by-step explanation:
To write an equation of a line knowing a slope and a y-intercept, you can use slope-intercept form, or y = mx+ b.
1) Lines that are parallel to each other have the same slope. The answer needs to be parallel to the line y = 2x, so whatever the slope of that equation is must be the slope of the answer, too.
y is isolated in y = 2x, meaning it is in slope-intercept form, or y = mx +b form. The m in y = mx + b represents the slope of the line. In the equation y = 2x, the 2 is in the place of that m - meaning that 2 is the slope of that line, and therefore the slope of the answer, too.
2) The question also says that (0,4) is a point the line must pass through as well. However, notice that the x-value of the point is 0, meaning it is positioned on the y-intercept. Therefore, (0,4) must be the y-intercept of the equation.
3) To write a linear equation with y = mx + b form, you need to replace the m and the b for real values. The slope is 2, and m represents the slope - so write 2 in place of the m. The b represents the y-value of the y-intercept point - knowing that point is (0,4), write 4 in place of the b. Therefore, the answer would be y = 2x + 4 (assuming the question can be written in slope-intercept form).

A value is decrease by 92% for a new value of 13.12 find the original value
Step-by-step explanation:
Decreased by 92% = 8% of original
8% of original value = New value = 13.12
100% of original value = 13.12 * (100/8) = 164.
The original value is 164.

90/5=18
18*3=54
Answer:
The answer is 54.
Step-by-step explanation:
Ok buddy
‣Remember that a right angle equals 90 degrees.
‣The numbers lie on a right angle.
‣So watchya gonna do is combine the like terms.
[tex]x + 2x + 2x = 5x[/tex]
‣In an equation, that finna look like:
[tex]5x = 90[/tex]
‣Solve that equation
[tex] \frac{5x}{5} = \frac{90}{5} \\ \\ x = 18[/tex]
‣Therefore, the value of x is 18.
‣We trynna find 3x so plug it.
[tex]3x \\ 3(18) \\ 54[/tex]
‣That fr is the answer, 54.
Jamie is helping out in the school library. He needs to figure out how many shelves the library staff should order for a new reading corner. There are 378 books for the reading corner. Each shelf holds 50 books. The librarian wants to put all the books on shelves. How many shelves should the library order?
Answer:
8 shelves
Step-by-step explanation:
First do 378 divided by 50 then you when you get your answer (with remaining numbers) you add one more book case so 378 divided by 50 is 7 then you have a remainder 28 so add another shelf which is now 8 shelves!
