Answer:
A (-5)
Step-by-step explanation:
The formula for slope is (y2-y1)/(x2-x1). Therefore, to find the slope for this problem, plug the numbers into the formula: (2-(-3))/(-2-(-1)) or (2+3)/(-2+1).
The cheerleaders at City High make their own
megaphones by cutting off the small end of a
cone made from heavy paper. If the small end of
the megaphone is to have a radius of 2.5 cm,
what should be the height of the cone that is cut
off?
2.5 cm
60 cm
Answer:
The height of the cone that is cut would be 2.5
A rectangle has a perimeter of 104 feet. If the
width of the rectangle is one more than twice its
length, determine the dimensions of the
rectangle.
Answer:
w=35, L = 17
Step-by-step explanation:
the perimeter is all sides added together to total 104. so,
2L + 2W= 104
the width is one more than twice it's length, so W = 2L + 1
plug that into first equation.
2L + 2(2L+1)=104
distribute:. 2L + 4L + 2= 104 and continue to solve for L
6L + 2= 104 subtract 2 from both sides.
6L = 102, divide both sides by 6
L = 17. so the length is 17 ft. now use that number to put it in our equation for width, W= 2L + 1
W= 2(17)+1
W = 35
At the end of the year, cars made in the current year are marked down to make room for next year's models. One particular model had a sticker price of $22,570 when it was new. It has just been marked down by 10%. What is the sale price of the vehicle?
Answer:
$20,313
Step-by-step explanation:
You're only reducing 10% of the cost so first you need to figure out what 10% of $22,570.
All you need to do is
22570×0.1=2,257
and then
22,570-2,257=20,313

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is °F. The submarine dives down 115 feet deeper, and the water temperature drops by °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation. Complete the steps below to solve the problem.Which operation must you use to find the water temperature after the submarine’s final dive? Which word or words in the problem signify this operation?
Answer:
The problem states that the temperature drops 2 degrees F. The word drops signifies that I should subtract 2 1/5 degrees F from 63 1/4 F.
Step-by-step explanation:

The product of a number and negative three is twenty-seven. Which of the following could represent this statement?
-3n + 27
-3(27) = n
-3n = 27
-3 = 27n
Answer:
-3n=27
Step-by-step explanation:
The value of n is -9.
So we can represent this in an equation. We won't get that as a result if we multiply the following
-3n=27 Divide -3 by both sides.
n=-9
Answer:
The product of a number and negative three is twenty-seven.
-3n=27

Use any method to multiply (–14ab)(a + 3b – 4c).
Question 2 options:
A)
–14a2b – 42ab2 + 56c2
B)
14a2b + 42ab2 + 56abc
C)
–14a2b – 42ab2 + 56abc
D)
–14a2b – 42a2b2 + 56c
Answer:
-14 a^2 b - 42 a b^2 + 56 a b c C. is the answer
Step-by-step explanation:
Expand the following:
-14 a b (a + 3 b - 4 c)
Hint: | Distribute -14 a b over a + 3 b - 4 c.
-14 a b (a + 3 b - 4 c) = -14 a b a - 14 a b×3 b - 14 a b (-4 c):
-14 a b a - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b a = -14 a^2 b:
-14 a^2 b - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b×3 b = -14 a b^2×3:
-14 a^2 b + -14×3 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and 3 together.
-14×3 = -42:
-14 a^2 b + -42 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and -4 together.
-14 (-4) = 56:
Answer: -14 a^2 b - 42 a b^2 + 56 a b c

Answer:
A, B, C, D, F . . . as written
Step-by-step explanation:
Any mixed number, fraction, or finite or repeating decimal is rational. The only one in your list that is irrational is E, which appears to be a non-repeating, non-terminating decimal.
__
Your B selection appears to be 11² = 121, an integer and a rational number.
If your B selection is supposed to be √11, then that number is irrational, as it is not the root of a perfect square.
E is irrational; B is rational as written, but irrational if it should be √11. All the others are rational.

find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure
Answer:
Area = 245m^2
Step-by-step explanation:
We can split this figure into 2 parts, a rectangle and a trapezoid.
Rectangle Sides = 10m and 20m
Area = 10m x 20m = 200m
Trapezoid formula = a+b/2(h)
a and b are the 2 bases and h is the height
Using a little deductive reasoning we get the following, 5+10/2(6)
This simplifies to 15/2(6) -->
7.5(6) = 45
Thus, our area is 200 + 45, or 245m^2
