The height of a stack of DVD cases is in a proportional relationship to the number of cases in the stack. A stack of 7 cases and its height are shown. Find the constant of proportionality. Then use the constant of proportionality to find the height of a stack of 12 cases.
Answer:
For a stack of 12 DVD cases, it will be 132mm in height
Step-by-step explanation:
There are 7 cases stacked on top of each other and the total height is 77mm.
Since you must find the height of each individual DVD case you have to divide the height (77mm) by the number of DVD cases (7):
77 / 7 = 11 or 77 ÷ 7 = 11
Then, it asks to find the height of a stack of 12 cases, so take the 11, the height of each DVD case, and multiply it by 12:
11 × 12 = 132
So, the height of 12 DVD cases stacked on top of each other is 132mm.

If the radius is 43, find
the diameter.
Answer:
Diameter = 86 units
Step-by-step explanation:
What is radius and diameter?
The radius of a circle is a straight line from the middle of a circle to its perimeter. The diameter of a circle is a straight line that touches the perimeter of the circle, then intersects with the center of the circle, and touches the perimeter of the circle again.How do we find the diameter?
The diameter of a circle is twice the radius, so 2 × 43 = 86 unitsThree people participated in a free throw shooting contest. Glenna made x shots, Val made 2x-10 shots, and Kim made x+10 shots. If a total of 180 shots were made, how many did each person make? Write and solve an equation.

A whale is at the surface of the ocean to breathe. The whale swims down 300 feet to feed. The whale swims down 150 more feet more. What is the whale’s elevation now?
Answer:
The whale's elevation is -450. This is because 300 + 150 = 450, making the whale 450 feet below sea level.

Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run? Explain
Answer:
6 miles
Step-by-step explanation:
A mile is 1760 yards; and hour is 3600 (=2x1800) seconds.
So a yard per second is roughly two miles per hour (actually 1800/1760 x2 miles per hour, so the error is about 40 in 1800 or less than 1 in 40, 2.5%) and three yards per second is about 6 miles per hour. Upper bound of the estimate would be 6 + 2.5% = 6+0.15 = 6.15 mph.

Which experession is equivalent to
8x + 4y - 2x + 6y - 3
A. 6x + 10y - 3
B. 6x + 2y - 3
C. 10x + 2y - 3
D. 10x + 10y - 3
Answer:
A
Step-by-step explanation:
8x+4y-2x+6y-3
combining like terms would give us
6x+10y-3
would is A
Hey there!
8x + 4y - 2x + 6y - 3
COMBINE the LIKE TERMS
= (8x - 2x) + (4y + 6y) - (3)
= 8x - 2x + 4y + 6y - 3
= 6x + 10y - 3
Therefore, your answer is:
6x + 10y - 3 (Optipn A.)

Solve for X please show work and or formula
The sum of angles in a triangle is always equal to 180 degrees
Add:
65 + 51 + x + 73 = 180
x + 189 = 180
x = -9 That is fine that x is "-9" because this would just mean that the angle "x+73" is just bigger than it is supposed to be.
Proof:
65 + 51 - 9 + 73 = 180
Therefore, x = -9
Answer:
x = -9
Step-by-step explanation:
Notes to remember:
A triangle's angles will always add up to 180°
--------------------------------------------------------------------
As the image shows, we have two labeled angles. A 51° angle and a 65° angle.
Here's how you want to set up your equation:
180° = 51 + 65 + x + 73
(Rearrange)
180° = 51 + 65 + 73 + x
Add 51, 65, and 73
180° = 189 + x
Subtract 189 from both sides, to isolate x.
-9° = x
ALWAYS PLUG IN (the number that comes from the variable) TO CHECK YOUR WORK!
180° = 51 + 65 - 9 + 73

Answer:
35.375
Step-by-step explanation:
Add −1.5 and 9.5 to get 8.
Multiply 0.4 and 18 to get 7.2.
Expand −0.2/7.2 ≈−36 by multiplying both numerator and the denominator by 10.
Divide 72 by −2 to get −36.
Convert 36 to fraction 8/288=36.
Subtract 288 from 5 to get −283.

I have 41 brainliests when I look at my account but when I look at my home page it says I only have 30 and yesterday it said I had 38/50 and now it says 30/50 and it keeps going down every time I get a new Brainliest, so does anyone know why?
karens prolly be deleting ur answers or questions that u answered which will take away ur points and brainliest
It happens to me too. My theory is that the home page only shows how many Brainliest you get in a day and the account shows how many you have in total. But I also think that the amount of Brainliest you have on your home page could just reset daily while your account keeps your total. This is just my opinion, I don't 100% know why.
