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.
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.
Three 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.
Answer: glenna made= 45 shots
val made= 2(45)-10=80shots
Kim made= 45+10= 55 shots

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.)

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.
-283/8 =35.375

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

The regular price of a pair of shorts was $58. During a sale, the price was reduced to
$43.50. Determine the percent discount. How would you do this? I know how to do it when it gives you the price before the discount and then it gives you the discount. But I was never taught how to do it this way.
DISCOUNT PERCENT = (MP - SP)×100%/MP
= (58-43.50)×100%/ 58
= 14.5×100%/58
=25%
