(PLEASE don't delete this. I really need help with this.)
Answer:
11.20
Step-by-step explanation:
I did this by first doing 5 x 5 x 5 which got me 125. Then I took 1400/125 to get 11.2. However you said round to the nearest hundredth which would be 11.20
substitute this equation
-1x-3y=4
2x=16
Answer:
x= 8 y= -4
Step-by-step explanation:2x=16 divide 2 on both, x=8, plug in 8 for x, -1x8-3y=4 will become = -8-3y=4 add 8 on both sides and divide by -3 the answer will be -4
Answer:
Step-by-step explanation:-
-1x - 3y = 4 (eqn 1)
2x = 16 (eqn 2)
from eqn 2
2x = 16
x = 16/2
x = 8
Substitute x = 8 into eqn 1
-1(8) - 3y = 4
-8 - 3y = 4
-3y = 4 + 8
-3y = 12
y = 12/-3
y = -4
therefore, x = 8 and y = -4
What’s the midpoint of a line segment joining the points (5,-4) and(-13,12)?
Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
((x1 + x2)/2 , (y1 + y2)/2)
((5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)
Here is a square of side 2a and an equilateral triangle of side a + 1

Step-by-step explanation:
use rhombus DEFG if GE=42 and DH=16 find GF
The value of GF in the rhombus is 26.4
Properties of a rhombus:All the sides are equalOpposite angles are equaladjacent angles are supplementaryDiagonals are perpendicular bisector of each otherTherefore,
DH = HF = 16
GH = HE = 21
Using Pythagoras theorem we can find GF as follows:
GF = √21² + 16²GF = √441 + 256
GF = √697
GF = 26.4007575649
GF = 26.4

When you measure an angle you usually have to choose between two numbers because
protractors are designed to measure angles that start on either the right or left side.
There are two angles to measure in each of the problems on this sheet and the next. The
angle on the left side is angle A. The angle on the right side is angle B. Find and record
the measure of both angles in each problem.

Answer:
85 Square Units
Step-by-step explanation:
We need to start by finding the area of the triangle:
(base*height)/2
[tex]\frac{17*10}{2} =85[/tex]
Then we find the area of the rectangle:
Height*Width= 170
Then we finally take the area of the rectangle (170) and subtract the area of the triangle (85) and we get the answer of 85.

Make a ratio and increase.
6:4
Find the least common multiples.
72:48
Next, take these 2 out of ratio form and add them together.
72
+48
120
Since the closest we get is 120...
We must change the LCM'S to get the true number. Either way, it will work if you reduce 48 by 2, or 72 by 2. Same answer.
[tex]120-2=118dollars\\72 - 2\\48 - 2[/tex]
Therefore,
Our problem answer can be seen as the original ratio, but modified, 72:48 or simply 70 + 48. For the ratio to be correct, you would have to factorize the least common multiples and re-add. I would not recommend this.

Peter can mow his lawn in 6 minutes. Peter's son can mow it in 8 minutes. How long will it take them to do it together?
Answer:
3 minutes 26 seconds
Step-by-step explanation:
rate x time in Distance problems, and W = rate x time in work problems. The Work is generally 1, the whole job.
For Peter the formula is 1 (lawn mowed) = 1/6 lawn per minute x 6 minutes.
For the son the formula is 1 = 1/8 * 8.
Add their rates together, 1/8 + 1/6 = 3/24 + 4/24 = 7/24.
The equation for their rate working together is 1 = 7/24 * t
Divide both sides by 7/24 to find t. t = 1 / 7/24 = 1 * 24/7 = 24/7 = 3 and 3/7 minutes = approx. 3 minutes 26 seconds.

Consider the function. Which conclusions can be drawn about f–1(x)? Select two options. F–1(x) has a slope of. F–1(x) has a restricted domain. F–1(x) has a y-intercept of (0, –36). F–1(x) has an x-intercept of (–36, 0). F–1(x) has a range of all real numbers.
The required function is [tex]y = -\frac{3}{2} x -36[/tex] having domain and range as R and y-intercept is -36.
Given function
y=f(x) = [tex]-\frac{2}{3} x -24[/tex]
What is an inverse function?An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function that gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.
In order to get inverse function [tex]f^-1x[/tex] let us arrange the given function
[tex]y+24 = -\frac{2}{3} x[/tex]
[tex]x = -\frac{3}{2} y-36[/tex]
Now, replace x with y and vice versa.
[tex]y = -\frac{3}{2} x -36[/tex]........(1)
or, [tex]f^-1x = -\frac{3}{2} x -36[/tex]
(1) will be the inverse function of the given function.
For x-intercept put y = 0 and for y-intercept put x=0 in eq(1)
x-intercept = -24
y-intercept = -36
The domain and range of f⁻¹x = set of all real numbers since f⁻¹x is a straight line equation, domain, and range of which is set of all real numbers.
Therefore, the required function is [tex]y = -\frac{3}{2} x -36[/tex] having domain and range as R and y-intercept is -36.
