Answer:
c). 14 < x < 15
d). 7 < x < 8
Step-by-step explanation:
c). (x/3)^3 = 124
Take the cube root of both sides
x/3 = 4.986630952238646
multiply both sides by 3
x = 14.959892856715938
14 < x < 15
-----------------------------
d). (x/2 - 1)^3 = 25
Take the cube root of both sides
x/2 - 1 = 2.924017738212866
Add 1 to both sides
x/2 = 3.924017738212866
multiply both sides by 2
x = 7.848035476425732
7 < x < 8
25% of what number is 8?
Answer:
32
Step-by-step explanation:
25% of 32 is 8. 100% of 32 is 32, therefore 25 percent of 32 equals 8.
If you know the length of the side of the square, how can you figure out the area?

Special Right Triangles (Radical Answers)
Answer:
x = [tex]5\sqrt{2}[/tex]
Step-by-step explanation:
We know that;
The triangle is isosceles, and the hypotenuse is x, the un-labeled side is 5.
Therefore we can say;
5² + 5² = x²
25 + 25 = x²
50 = x²
[tex]\sqrt{50}[/tex] = x
We can simplify this further;
[tex]\sqrt{25} * \sqrt{2}[/tex] = [tex]\sqrt{50}[/tex]
[tex]5\sqrt{2}[/tex] = [tex]\sqrt{50}[/tex]
Hope this helps!

Answer:
35 yards
Step-by-step explanation:
The formula for an area of a trapezium or trapezoid is h(a+b)/2. H is the height, and a and b are the the two opposite sides. With substitution, we get 5(6+8)2 = 70/2 = 35
Answer:
35 yd²
Step-by-step explanation:
First, you need to find the remaining side:
You need to find the bottom side of the triangle: 8-6=2 yd
Let's calculate the area of the triangle:
[tex]\frac{5*2}{2} =5[/tex] yd²
Let's calculate the area of the rectangle:
6*5 = 30 yd²
Total area: 30+5 = 35 yd²
What are the center and the radius of the circle whose equation is (x-5)^2+(y+3)^2=16
CENTER : ( 5, -3)
RADIUS : 4
Answer:
Center (5,-3)
radius : 4
Step-by-step explanation:
Radius: is the square root of 16. The square root of 16 = +/- 4. Minus 4 has absolutely no meaning for a question like this so the radius is 4. Rule take the square root of the counting number on the right.
The center is the value when x - 5 =0 and y + 3 = 0
x - 5 = 0
x = 5
y + 3 = 0
y = -3

==================================================
Explanation:
This is a 30-60-90 triangle. The short leg 5 is opposite the smallest angle 30 degrees.
The long leg is sqrt(3) times that of the short leg, which explains why x = 5*sqrt(3).
The hypotenuse is twice as long compared the short leg, so y = 2*5 = 10.
You could use trig ratios and the unit circle as another way to find x and y.

Answer:
E) 25.5 units²
Step-by-step explanation:
The figure is not carefully drawn, so it is difficult to tell that it is a trapezoid. The "height" of it is BC, the diagonal of a rectangle that is 1 unit by 4 units. The Pythagorean theorem tells you that length is ...
BC = √(1² +4²) = √17
We notice that the "bases" of the trapezoid (CD and AB) are 1 and 2 times this length. The trapezoid area formula tells us the area is ...
A = 1/2(b1 +b2)h
A = 1/2((√17)(1 +2))(√17) = 3/2(17) = 25.5 . . . . square units
_____
Alternate solution
Pick's Theorem is a theorem that can help you find the area of a polygon when its vertices are all on grid points. It tells you the area is ...
A = i + b/2 -1
where i is the number of grid points interior to the figure, and b is the number of grid points on the boundary. Here, the boundary grid points are those that are labeled plus the one at (-2, 1). Counting the interior grid points gives a total of 24, so the area by Pick's theorem is ...
A = 24 + 5/2 -1 = 25.5 . . . square units
__
Additional comment
Once you're familiar with Pick's theorem (and/or any of a few other methods of computing area from coordinates), you see that the area of any polygon whose vertices are grid points will be an integer multiple of 1/2. The only such answer choice here is choice E.
Tamsen pays $12.50 of her monthly life insurance premium, and her
employer covers the rest. If her monthly premium is $42.25, what is the
annual value to Tamsen of this benefit?
A. $150
B. $357
C. $507
D. $328.50
Benefit she gets monthly is = 42.25-12.5= 29.75
annual value to Tamsen of this benefit= 12×29.75 = 357$
why in math, whenever you do an explanation, for example, 2x - 20, the subtraction sign make the 20 a negative number?
Answer:
The negative sign is put before numbers to make them negative, or make their signs the opposite of what the are.
You have a 20.
+ 20
You don't need to put the + there if there is nothing before it, but that is a positive 20.
If you put a negative in front of it;
- (+ 20) = - 20
If you have a negative in front of parenthesis;
50 - (2x - 20)
50 - 2x + 20
70 - 2x

Drag and drop each choice into the correct boxes to complete the description of how to find the sums -2 + 1 and -2 + (-1) on a number line
Answer:
a. -1
b. -3
Explanation:
To solve negative and positive numbers on the number line, we make a simple analogy. If we wanted to -3+2 for instance:
Imagine a customer placed an order for 3 bags of apples from your store but you are out of stock and only have 2 bags left. You then come to an agreement with the customer to send 2 bags now and send the remaining one later in the week when your stock arrives from your supplier. In this way, you are only able to send two bags which you have,+2, and then be owing the customer one bag left(-1) to deliver out of the three, -3.
To solve -2+1 on the number line, with -2 on the left side of 0(negative) on the number line and +1 on the right side of 0(positive), we use same analogy above.
-2+1= -1
Also using same analogy, -2+(-1)= -3
Note: +1×-1=-1

Answer:

Step-by-step explanation:
Because the triangle is equilateral and is cut by the bisector, both triangles are 30-60-90 triangles. Therefore, to find side x, you multiply the short side by √3. This means that side x is √10*√3=√30 units.

Which triangle is a translation of the gray triangle
Answer:
Triangle DEF
Step-by-step explanation:
Hi there!
A translation of a shape occurs when all the coordinates of the original image is shifted up, down, left or right by an equal value.
Triangle ABC is a reflection of the grey triangle across the y-axis. We know this because the y-axis acts like a line of symmetry between the two shapes.
Triangle DEF appears as if it's been shifted. Therefore, triangle DEF is a translation of the grey triangle.

What is the equation of the line that is parallel to the line x = -2 and passes through the point (5.4)?
Lines parallel to each others only occur when two slopes of equations are same. The definition of parallel lines is:
[tex] \large \boxed{m_1 = m_2}[/tex]
We are given the equation of a line which is x = -2. For x = a, the equation forms a verical line and has an undefined slope. These below are basic that you may need to learn when learning about the line graph:
y = a —> horizontal line; slope is 0.x = a —> vertical line; slope is undefined.For y = a, any a-values would have same x-values. For example, if we are given y = 2 then any domains or x-values can have the range of 2.For x = a, any a-values would have same y-values or range.Back to the question. We want to find the equation of a line that is parallel to the line x = -2 and passes through (5,4) point. Recall the definition of parallel line that both slopes of equations must equal. Since x = a for any a-values would give an undefined slope. That means our parallel would be x = b.
Because the line passes through (5,4) - for any a-values from x = a would give out the set of all real numbers for range. Therefore the equation of a line is x = 5.
Answer
The equation of a line that is parallel to x = -2 and passes through (5,4) is x = 5.I hope this helps! If you have any doubts or questions, don't hestitate to ask in comment! Good luck on your assignment and have a great day!

The area of the pathway is square, and its area is 196 square cm. Find the length of the pathway.
Answer:
14 cm
Step-by-step explanation:
Use the formula for the area of a square, a = s², where s is the side length of the square.
Plug in 196 as the area, then solve for s.
a = s²
196 = s²
14 = s
So, the length of the pathway is 14 cm
help the volume of the roller is 576cm. Calculate the height and area of the roller if its radius is 8cm.
Answer:
143.7cm^2
Step-by-step explanation:
Given data
Volume= 576cm^3
Radius= 8cm
The expression for the volume of cylinder is
V= πr^2h
substitute
576= 3.142*8^2*h
576= 3.142*64*h
576= 201.088h
h= 576/201.088
h=2.86cm
The formula for finding the lateral area of a right circular cylinder is:
A=2πrh
substitute
A= 2*3.142*8*2.86
A= 143.7cm^2
Hence the area is 143.7cm^2

The Malcolms are taking a trip. Midville is 214 miles
from their home. Walesburg is 3 times as far.
How far is Walesburg from their home?
Answer:
642 miles
Step-by-step explanation:
Distance of Midville from their home = 214 miles
Walesburg is 3 times as far.
How far is Walesburg from their home?
Distance of Walesburg from their home = 3 × Distance of Midville from their home
= 3 × 214 miles
= 642 miles
Distance of Walesburg from their home = 642 miles
