Answer:
x > -2
Step-by-step explanation:
-3x + 2 < 8
our goal is to isolate the x
subtract two from both sides
-3x < 8 - 2
- 3x < 6
divide both sides by -3
flip the sign because we divided by a negative number
x > -2

Identify the similar triangles in the figure then find the value of X.
A. Write the similarity statement in the form of triangle~triangle.
B. What is the value of X.
Answer:
A. ∆ABD ~ ∆CDE
B. x ≈ 5.3
Step-by-step explanation:
A. The Acute Angle Similarity Theorem states that when an acute angle in one right triangle is congruent to a corresponding acute angle in another, both right triangles are said to be similar to each other.
<B ≅ <D (both are right angles)
<A ≅ C,
Therefore, ∆ABD ~ ∆CDE
B. Since ∆ABD ~ ∆CDE, corresponding sides would be proportional to each other. This means that:
DE/BD = CD/AB
Substitute:
6/8 = 4/x
Cross multiply
6*x = 4*8
6x = 32
6x/6 = 32/6
x ≈ 5.3 (nearest tenth)

PLEASE HELP!!!!! find the measure of the arc or central angle indicated. assume that lines which appear to be diameters are actual diameters.
Answer:
B
Step-by-step explanation:
Remark
If you started at W and went all the way around the circle until you wound up back at W, you will have gone 360 degrees. Since the angle measurement that prevents that is 85 degrees, the answer must be 360 - 85 = 275.
Answer:
275
Step-by-step explanation:
The angle start in V then goes the left to Y and ends in W
First you add the First 34 degrees from V to U.
Then the 90 degrees from U to Y. (you can see it has a square on the angle therefore its 90).
After that you add another 36 degrees from Y to X.
Finally to get the unknown angle from X to W you subtract all the other angles from 360 degrees.
360-245=115
Then add all the angles and you get 275 degrees.
Might be wrong but I think its correct

Find the volume of the right prism with a cylindrical hole. Round to the nearest tenth.
Answer:
11.2
Step-by-step explanation:
First, you get the volume of the right prism by multiplying the length times the width times the height, which is 2.5 cubed. Then we subtract the volume of the cylindrical hole. We do this by doing pi times the radius squared times the height, which is pi times 0.75 squared times the height. This will yield 11.2 cubic millimeters.
The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x
Answer:
85.1 ft
Step-by-step explanation:
The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x
We solve using the Trigonometric function of Cosine
cos y = adjacent/hypotenuse
y = angle = 20°
Adjacent = 80 ft
Hypotenuse = ?
cos 20 = 80/Hypotenuse
Hypotenuse = 80/cos 20
x = 85.134221798 ft
Approximately = 85.1 ft
Length of the slide = 85.1 ft

The red numbers are the ones that are given in the problem text. The blue numbers are calculated so as to make row and column totals come out properly.
The drink total shows the same number is arrived at either of two ways. This is confirmation that the other numbers are calculated properly.
Use I = P R T I=PRT to find the total amount in the savings account. Type in "money form". $1000.00 at 2.365% for 3 years
Answer:
70.95$
Step-by-step explanation:
P = $1000
R = 2.365%
T = 3 years
[tex]\frac{PRT}{100}[/tex] = [tex]\frac{1000*2.365 * 3}{100}[/tex] = [tex]\frac{7095}{100}[/tex] = 70.95$

The cost for bowling includes $4.00 for shoes and $4.75 for each
game bowled. Which equation represents the amount, in dollars, y,
for x games bowled?
Answer:
y = 4.75x + 4
Step-by-step explanation:
it would be $4.75 for each game and you would only pay for shows once
The equation that represents the amount, in dollars, y,
for x games bowled is y = 4.00 + 4.75x
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The cost for bowling includes a fixed cost of $4.00 for shoes, and an additional cost of $4.75 for each game bowled.
y = 4.00 + 4.75x
This equation can be interpreted as follows: the fixed cost of $4.00 is added to the variable cost of $4.75 per game, multiplied by the number of games bowled (x).
The result is the total cost, represented by y
Therefore,
The total cost for x games bowled can be represented by the equation:
y = 4.00 + 4.75x
where y is the total cost in dollars, and x is the number of games bowled.

[tex]\begin{bmatrix}-1 & 2 \\ \frac{3}{2} & -\frac{5}{2} \end{bmatrix}[/tex]
Step-by-step explanation:
Inverse of a matrix is given by,
[tex]\begin{bmatrix}a & b\\ c & d\end{bmatrix}=\frac{1}{ad-bc}\begin{bmatrix}d & -b\\ -c & a\end{bmatrix}[/tex]
By using this property,
[tex]\begin{bmatrix}5 & 4\\ 3 & 2\end{bmatrix}^{-1}=\frac{1}{(5\times 2-4\times 3)}\begin{bmatrix}2 & -4\\ -3 & 5\end{bmatrix}[/tex]
