Answer:
The computer costs $212.5
Step-by-step explanation:
First you multiply the original ammount by the percentage,or 15%,which is 0.15.Then you take that amount and subtract it from the original price.
[tex]250*0.15=37.5\\\\250-37.5=212.5[/tex]
The answer is $ 212.5 Dollars
The Maron Luggage Company claims they have a suitcase large enough to fit a 34-inch baseball bat inside. If the suitcase has height and depth 17 inches by 11 inches, what must its whole-number length be, at minimum?
Answer:
the height of the suitcase is 34 in
Step-by-step explanation:
Given that
The length of the baseball bat is 34 in
And, the height and depth of suitcase is 17 inches by 11 inches
Based on the above information
The height of the suitcase would be equivalent to the height of the baseball bat i.e. 34 in
Hence, the height of the suitcase is 34 in
The same would be considered

Add the following rational numbers: 5/8 and 3/-10
Answer:
= 13/40
Step-by-step explanation:
(5/8) + (3/-10)
5/8 = 50/80
3/-10 = -24/80
then:
(5/8) + (3/-10) = 50/80 - 24/80
= 26/80 = 13/40
Answer:
13/40

If the spinner shown is spun 40 times, predict the number of times the spinner would land on Section B.
Answer:
10 times
Step-by-step explanation:
Given that:
Number of sections = (A, B, C, D) = 4
Probability of spinner landing on section B on a single spin = required outcome / Total possible outcomes
P(landing on B) = 1 /4
Predicted Number of times spinner will land on D ; if spinner is spurned 40 times
1/4 * 40 = 10 times

Answer:
1. 53
2. 20
3. 37
4. 29
Step-by-step explanation:
Since your trying to find the hypotenuse you equation is...
1. 28^2 + 45^2 = C^2
784 + 2025 = C^2
Square Root 2809= C^2
C=53
So after you square root 2809 you get 53.
2. 12^2 + 16^2 = C^2
144 + 256 = C^2
Square Root 400 = C^2
C=20
So after you square root 400 you get 40.
3. 12^2 + 35^2 = C^2
144 + 1225 = C^2
Square Root 1369 = C^2
C=37
So after you square root 1359 you get 37.
4. 20^2 + 21^2 = C^2
400 + 441 = C^2
Square root 841 = C^2
C=20
So after you square root 841 you get 29.

The cone and cylinder above have the same radius and height. The volume of the cone is 210 cubic centimeters. What is the
volume of the cylinder?
Answer:
706.3 cm³
Step-by-step explanation:
Given
"The cone and cylinder above have the same radius and height..."
the volume of the cone = 210 cubic centimeters
Formula
The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.
How to solve
Given radius and height calculate the volume, lateral surface area, and total surface area.
Calculate V, L, A | Given r, h
use the formulas above
Given radius and volume calculate the height, lateral surface area, and total surface area.
Calculate h, L, A | Given r, V
h = V / πr2
Given radius and lateral surface area calculate the height, volume, and total surface area.
Calculate h, V, A | Given r, L
h = L/2πr
Given the height and lateral surface area calculate the radius, volume, and total surface area.
Calculate r, V, A | Given h, L
r = L/2πh
Given height and volume calculate the radius, lateral surface area, and total surface area.
Calculate r, L, A | Given h, V

x-y = -10 2x+4y=22 substitution
Answer:
[1] x - 4y = 22
[2] 2x + 5y = -21
Step-by-step explanation:
Solve equation [1] for the variable x
[1] x = 4y + 22
// Plug this in for variable x in equation [2]
[2] 2•(4y+22) + 5y = -21
[2] 13y = -65
// Solve equation [2] for the variable y
[2] 13y = - 65
[2] y = - 5
// By now we know this much :
x = 4y+22
y = -5
// Use the y value to solve for x
x = 4(-5)+22 = 2

Answer:
x = 23 degrees
Step-by-step explanation:
It is given that the two parallel lines, (m) and (n) are intersected by a transversal. The two given angles (5x - 20) and (85) are alternate corresponding. Meaning that they are supplementary; their angle measures add up to (180) degrees. Based on this given information, form an equation and solve for the parameter (x).
(5x - 20) + (85) = 180
Simplify,
5x + 65 = 180
Inverse operations,
5x + 65 = 180
-65 -65
5x = 115

P(fewer than 7 boxes) -

[tex]P(x < 7) = 0.383[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
Determine the probability that few than 7 boxes will be needed.
This is represented as:
[tex]P(x < 7)[/tex]
And the solution is:
[tex]P(x < 7) = P(x = 4) + P(x = 5) + P(x = 6)[/tex]
Each probability is calculated by dividing the number of dots by the total dots.
So, we have:
[tex]P(x < 7) = \frac{n(x = 4) + n(x = 5) + n(x = 6)}{Total}[/tex]
From the attached, the formula becomes:
[tex]P(x < 7) = \frac{4 + 6 + 3}{4+6+3+4+4+6+3+2+1+2+0+1}[/tex]
[tex]P(x < 7) = \frac{13}{36}[/tex]
[tex]P(x < 7) = 0.361[/tex]

B. g(x) = 1x1 + 4
O c. g(x) = (x - 41
O D. g(x) = (x + 41
Answer:
D
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Here g(x) is the graph of f(x) shifted 4 units to the left , then
g(x) = | x + 4 | → D
The equation of function g(x) is [tex]g(x) = |x + 4|[/tex]
From the graph, we have the following highlights
The blue line represents f(x)The orange line represents g(x)Also, the blue line is shifted 4 units to the left, to get g(x)
The rule of this transformation is:
[tex](x,y) \to (x + 4,y)[/tex]
So, we have:
[tex]g(x) = |x + 4|[/tex]
Hence, the equation of function g(x) is [tex]g(x) = |x + 4|[/tex]

the points m(-10, 3) and p(-4, -8) are graphed on the coordinate plane. to the nearest tenth of a unit what is the distance between points m and p
Answer:
Distance between points m and p = 12.53 unit (Approx.)
Step-by-step explanation:
Given:
Co-ordinate of points
m(-10, 3)
p(-4, -8)
Find:
Distance between points m and p
Computation:
Distance between two points = √(x1 - x2)² + (y1 - y2)²
Distance between points m and p = √(-10 + 4)² + (3 + 8)²
Distance between points m and p = √(-6)² + (11)²
Distance between points m and p = √36 + 121
Distance between points m and p = √157
Distance between points m and p = 12.53 unit (Approx.)

The endpoint of the line segment will be (-1, 4) and (2, 0). Then the correct options are B and E.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
Section Stomach muscle has endpoints A(- 2, 8) and B(4,0). The section is widened at the beginning by a scale variable of 0.5 to make a fragment of the Stomach muscle.
The endpoint of the line segment is given as,
A = 0.5(-2, 8)
A = (-1, 4)
B = 0.5(4, 0)
B = (2, 0)
The endpoint of the line fragment will be (- 1, 4) and (2, 0). Then the right choices are B and E.
