Answer:
y = 3x + 2
Step-by-step explanation:
1. Work out the gradient of the line segment: change in y/change in x: -2 - -6/ -8 - 4 = 4/-12 = -1/3
2. Work out the gradient of the perpendicular bisector: the gradient of the line segment and the perpendicular bisector should multiply to get -1. This means that we can do -1 ÷ -1/3 to work out the gradient which is 3
4. Find the midpoint of the line segment: (-8 + 4) ÷ 2 = -2, and (-2 + -6) ÷ 2 = -4, so the midpoint is (-2, -4)
3. The equation will be in the format y = 3x + c and will go through (-2, -4), so we can substitute those values into the equation to find c:
y = 3x + c-4 = 3(-2) + c-4 = -6 + cc = -4 + 6c = 2The equation of the line is y = 3x + 2
Hope this helps!

x = 7
All 8 angles measure 135°
Step-by-step explanation:
(n-2)·180 = (8-2)·180 = 1,080°; this is the total of all interior angles
each angle is equal so we can divide 1080 by 8 and find that each angle measures 135°
to solve for 'x':
16x + 23 = 135
16x = 112
x = 112/16
x = 7
check: 16(7) + 23 = 135
112 + 23 = 135
135 = 135
Katherine has a fish tank shaped like a triangular prism in her living room. The triangle that forms the base of the tank has a base of 24 inches and a height of 20 inches. The entire tank is 36 inches tall. What volume of water is needed to fill the tank if the tank is only filled to 6 inches below the top?
Answer:
[tex]Volume = 7200in^3[/tex]
Step-by-step explanation:
Given
[tex]B = 24[/tex] --- base of the tank base
[tex]h = 20[/tex] --- height of the tank base
[tex]H = 36[/tex] --- height of the tank
Required:
Determine the volume of water needed for 6 inches below the top
First, calculate the area of the tank base.
[tex]Area = \frac{1}{2}Bh[/tex]
[tex]Area = \frac{1}{2}*24*20[/tex]
[tex]Area = 12*20[/tex]
[tex]Area = 240[/tex]
If the tank is filled 6 inches below the top, this means that the height of the water is H - 6.
So, the volume is:
[tex]Volume = Area * (H - 6)[/tex]
Substitute 240 for Area and 36 for H
[tex]Volume = 240 * (36 - 6)[/tex]
[tex]Volume = 240 * 30[/tex]
[tex]Volume = 7200in^3[/tex]

1) Solve 12.5 +8= 27.
What does s=
Answer:
there is no s in the question please explain
Step-by-step explanation:
Answer:
S = 6.5
Step-by-step explanation:
12.5 + 8 = 20.5,
27 - 20.5 = 6.5
therefore s = 6.5
Checking work
12.5 + 8 + s =
12.5 + 8 + 6.5 = 27

Answer:
[tex]-\frac{1}{55}[/tex]
Step-by-step explanation:
Hi! Ace here.
Whenever we have a positive being added to a negative, we can just do the positive subtracted my negative.
So let's rewrite this:
[tex]\frac{4}{5} -\frac{9}{11}[/tex]
When subtracting and adding fractions, we have to make sure there is a common denominator, and if there isn't a common denominator, then we make a common denominator. The LCM, in this case, is 55, so let's convert the fractions.
[tex]\frac{4}{5} *\frac{11}{11} =\frac{44}{55}[/tex]
[tex]\frac{9}{11} * \frac {5}{5} = \frac{45}{55}[/tex]
Since [tex]\frac{11}{11}[/tex] and [tex]\frac{5}{5}[/tex] both equal 1, the fraction is the same value.
Now we subtract normally with our "new" numbers.
[tex]\frac{44}{55}- \frac{45}{55}[/tex][tex]=-\frac{1}{55}[/tex]
I hope this helped, let me know if you have any questions.

Caleb and Suzanne each have a pile of blue and white chips. Caleb determines in his pile,three out of every four chips is blue. Suzanne determines in her pile, one out of every five chips are blue. How many total chips does each student have if Caleb and Suzanne each have 6 blue chips?
Answer:
Total number of chips Caleb have = 8
Total number of chips Suzanne have = 30
Step-by-step explanation:
In Caleb case -
Three out of every four chips is blue
⇒ If Caleb has total chips = 4
Then Blue chips = 3
⇒White chips = 4 - 3 = 1
Now,
If Caleb have 6 blue chips
⇒3 Blue chips = 4 total chips
1 Blue chip = [tex]\frac{4}{3}[/tex] total chips
⇒6 blue chips = [tex]\frac{4}{3}[/tex] ×6 = 4×2 = 8 total chips
∴ we get
Number of chips become = 8
In Suzanne case -
One out of every five chips are blue.
⇒ If Suzanne has total chips = 5
Then Blue chips = 1
⇒White chips = 5 - 1 = 4
Now,
If Suzanne have 6 blue chips
⇒1 Blue chips = 5 total chips
⇒6 blue chips = 5×6 = 30 total chips
∴ we get
Number of chips become = 30

If = 58° and m = 120 in, what is the value of p to the nearest tenth of an inch?
Answer:
141.5 in
Step-by-step explanation:
sin 58 = m/p = 120/p
120 = psin58
120/sin 58 = p
p = 141.5 in.
Another way to look at this problem is to remember that the hypotenuse of a right triangle is the longest side. Since 141.5 is the only answer greater than 120, it would have to be the logical choice for the length of p
-3r+5r
What is the answerrr i need helpp :((((
Answer:
2r
Step-by-step explanation:
2r is the answer because:
We have to switch the -3r in to +3r and positive + positive = positive.
Then we change the add sign in to subtracting sign and we subtract:
3r-5r and it will give us:
2r
And we keep the answer positive because our answer was a +5r so the bigger number keeps the sign the same.

There are 560 students in a school.If the ratio of the boys are girls is 4:3,find their numbers.
Answer:
320 / 240 = 4 / 3
Step-by-step explanation:
4 / 7 = x / 560
Cross-multiply:
7x = 2240
Divide by 7:
x = 320
The school has 320 boys and 240 girls.
hope this helps
Answer:
320 : 240
Step-by-step explanation:
4 + 3 = 7
560 / 7 = 80
so 1 is 80
4 x 80 : 3 x 80
320 : 240

What is The slope of (6,5) and (14,35)
Answer:
15/4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(35-5)/(14-6)
m=30/8
simplify
m=15/4
Answer:
Step-by-step explanation:
Slope is defined as
m=(y2-y1)/(x2-x1), we have points (6,5) and (14,35) so
m=(35-5)/(14-6)
m=30/8
m=3.75
