equation 9x+8=4x+18
angle measure 26
Explanation:
9x+8=4x+18
-4x = -4x
5x+8=18
-8 = -8
5x=10
x=10/5
x=2
---
so... now plug in 9(2)+8 = 18+8=26degrees
to confirm the angle should be the same for the next one
4x+18=26
solve for x
26-18=4x
8=4x
8/4=x
2=x
The perimeter of a rectanglar field is 334 yards. If the widths the field is 78 yards, what is its length
Answer:
The length of rectangular field is 129 yards.
Step-by-step explanation:
Given that
Perimeter = P = 334 yards
Width = w = 78 yards
Length = l = ??
We will use the perimeter of the formula to find the length of rectangle.
The perimeter of a rectangle is given by:
[tex]P = 2(l+w)[/tex]
Putting the values of perimeter and width
[tex]334 = 2(l+38)\\334 = 2l+76\\334-76 = 2l+76-76\\258 = 2l\\\frac{2l}{2} = \frac{258}{2}\\l = 129[/tex]
Hence,
The length of rectangular field is 129 yards.

The height of a cylinder with a fixed radius of 6 cm is increasing at the rate of 3 cm/min. Find the rate of change of the volume of the cylinder (with respect to
time) when the height is 20 cm.
A. 36Pi
B. 108pi
C. 360pi
D. None of these
Answer:
108π cm^3/min
Step-by-step explanation:
At a time of t min, let the height be h cm
The volume of a cylinder;
V = π r^2 h
= 36π h
differentiating both sides with respect to t;
dV/dt = 36π dh/dt
but dh/dt = 3 cm/min
dV/dt = 36π(3) = 108π cm^3/min
What is the value of x in the equation 3x-15=-18
Answer:
x = -1
Step-by-step explanation:
3x - 15 = -18
Add 15 to both sides;
3x = -3
Divide both sides by 3;
x = -1
Answer:
X=-1
Step-by-step explanation:
3x-15=-18
+15 +15
3x=-3
x=-1

A man buys furniture that has a list price of $255. He is allowed a discount of 12%
but must pay a sales tax of 3% on the cost. Which of the following is the amount he
actually pays for the furniture:
(A) $217.67
(B) $231.13 (C) $224.40 (D) $232.50 (E)
none of these.
Answer:
Option B. $231.13 is the correct answer.
Step-by-step explanation:
Given that
Listed price of furniture = P = $255
Discount = d = 12%
Sales tax = s = 3%
First of all, we have to find the discounted price by calculating the discount first
So,
[tex]Discount = 12\%\ of\ P\\= 0.12*255\\= 30.6[/tex]
Discounted Price:
[tex]= Listed\ Price - Discount\\= 255 - 30.6\\= 224.4[/tex]
The sales tax will be calculated on the discounted price
So,
[tex]Sales\ tax = 3\%\ of\ Discounted\ price\\= 0.03 * 224.4\\= 6.732[/tex]
Now,
[tex]Final\ price\ of\ furniture = Discounted\ price + Sales\ tax\\= 224.4 + 6.732\\=231.132[/tex]
He will actually pay $231.132 for the furniture.
Hence,
Option B. $231.13 is the correct answer.

Write an equation of the line that passes through a pair of points (2,3),(4,-2)
Answer:
y=-5/2x+13
Step-by-step explanation:
m=(-2)-3/4-2
m=-5/2
y-y=m(x-x1)
y-3=-5/2(x-2)
y-3=-5/2x+10
+3 +3
y=-5/2x+13

If the radius of the circle is 7 cm, find its area, rounded to 2 decimal places.
A= _______ cm2
Answer:
153.94
Step-by-step explanation:
The formula for area is pi*radius^2
the radius is 7, so we do pi7^2 which is 49pi
49pi is 153.93804 which is 153.94 rounded to two decimal places

a = √4100
a = 64.03
Evalulate 7 3/4+(-2 1/5) x for x =-10
Answer:
2884
Step-by-step explanation:
First plug in -10 for x, which would look like this: 734 + (-215 * (-10) ) =
Then, first you calculate everything in the parenthesis, which is (-215) * (-10)
and the equation would look like this after you multiply: 734 + 2150 =
If you noticed the number turned out positive after we multiplied, that is because - number times a - number would always be positive, just like if you divide - number by a - number your answer would be positive.
Your last step would be adding 734 with 2150. : 734 + 2150 = 2884
+ 734
2150
_____
2884
And the answer would be 2884
