Please help! I need this correct,
Answer:
A. 56
Step-by-step explanation:
If you look at the image, I cut the shape in half.
So the shape on the bottom not can be multiplied as such: 8x2x2
8x2=16 then 16x2=32.
Since the shape cut in half, the sides are now 2 instead of 4.
Now you can multiply the top shape by: 2x6x2
2x6=12 then 12x2=24.
After you have the volume of both shapes, you add the volumes together.
32+24=56 Then your answer should be A. (Hope this helps!)

Answer:
Radius is 2.8 Circumference is 17.584 or 17.6 Rounded to the nearest Tenths
Step-by-step explanation:
1. Find circumference with the Formula C=πd
C=3.14 x 5.6
C=17.584 or 17.6 Rounded to the nearest Tenths
2. Radius is Always half of the Diameter.
5.6/2 = 2.8
2.8 is your radius.
3. If you want to check you work try the formula C=2πr to see if things checks out.
C=2 x 3.14 x 2.8
C= 17.584 or 17.6 Rounded to the nearest Tenths

Which equation represents the relationship between the x-values and y-values in the graph?
The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, -5) and (5, -2).
Now,
Since, The equation of line passes through the points (0, -5) and (5, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - (-5)) / (5 - 0)
m = 3 / 5
m = 3/5
Thus, The equation of line with slope 3/5 is,
⇒ y - (-5)= 3/5 (x - 0)
⇒ y + 5 = 3x/5
⇒ y = 3x/5 - 5
Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5

what is 6n + 7 - 2n - 14 = 5n + 1
Answer:
-7 is what i got
Step-by-step explanation:
combine like terms.. 6n -2n= 4n
7-14= -7
4n-7= 5n+1
+1 becomes -1
4n- -6=5n
-4n on both sides
-6= 1n
1-1 on both sides to cancel out
n= -7

Can someone help me find the Slope to these to pleaseeee?
Answer:
Remember the slope formula:
m= y2-y1/x2-x1
11. (-1,3) (3,3)
= 3-3/3--1
= 0/4
m = 0
12. (1,3) (1, -2)
= -2-3/1-1
= -5/0
= undefined
For the future, know that the slope of horizontal lines is always zero and the slope of vertical lines is always undefined.

#3-60 Simplify the following expressions.
Answer:
The solution is:
a. -18
b. -18
c. 24
d. 0
e. -4
4. 4
Step-by-step explanation:
Before we get into the solution, we remember the formula first, namely:
Addition
• (-) + (-) = (-)
• (+) + (+) = (+)
Subtraction
• (+) - (+) = can (-) and (+)
• (+) - (-) = (+)
Multiplication
• (-) x (-) = (+)
• (+) x (-) = (-)
Division
• (-) : (-) = (+)
• (+) : (-) = (-)
Solution:
a. 6(-3) = -18 ((+) × (-) = (-))
b. -6(3) = -18 ((-) × (+) = (-))
c. (-8)(-3) = 24 ((-) × (-) = (+))
d. -8(0) = 0 (whatever the number, if multiplied by 0 the result is still 0)
e. -20÷5 = -4 ((-) ÷ (+) = (-))
f. -36÷(-9) = 4 ((-) ÷ (-) = (+))
What value of Y makes the equation true ?
Answer:
y = -5/2 or -2.5
Step-by-step explanation:
3y + 4 = -y - 6
add y to both sides
4y + 4 = -6
subtract 4 from both sides
4y + 4 - 4 = - 6 - 4
4y = -6 - 4
4y = -10
divide both sides by 4
4y/4 = -10/4
y = -10/4
y = -5/2 or -2.5
