The total value of the pennies and nickels was $14.50. Hala counted the coins and found there were 450 coins in all. How many of each type of coin did she have?
Answer:
Hala will have 200 Pennies and 250 nickels.
Step-by-step explanation:
Let x be = number of Pennies
Let y be = number of nickels
x + y = 450
-x -x
——————
y = -x + 450
0.01x + 0.05y = 14.50
0.01x + 0.05( -x + 450 ) = 14.50
0.01 - 0.05x + 22.5 = 14.50
-0.04x + 22.5 = 14.50
-22.5 -22.5
———————————-
-0.04x = -8
——— —
-0.04 -0.04
x = 200
200 + y = 450
-200 -200
————————
y = 250
If the exterior angle of a regular
polygon measures 12°, how
many sides does the polygon
have?
Work Shown:
E = exterior angle = 12 degrees
n = number of sides
n = 360/E
n = 360/12
n = 30
This regular polygon has 30 sides.
The radius of a circle is 10 meters. What is the length of a 135° arc?
Answer:
Step-by-step explanation:
The total circumference of the circle is: C = 2*pi*radius = 2*(3.14159)*(6) = 37.7 m The total circle has 365o. Your arc has only 135o. Hence: 135o x------- = -------------365o 37.7 m where x is the length of the 135o arc. Solve for x.

Last week, Kip went to the fair. It costs $4.95 to enter the fair and $0.50 per ticket. In the equation below, x represents the number of tickets Kip bought, and y represents the total amount Kip spent.
y = $0.50x + $4.95
If Kip spent $12.45 at the fair, how many tickets did he buy?
Group of answer choices

Answer:
x = 15
Step-by-step explanation:
[tex]12.45=4.95+0.5\timesx[/tex]×x
Solve the equation
[tex]12.45=4.95+0.5x[/tex]
Rearrange variables to the left side of the equation
[tex]-0.5x=4.95-12.45[/tex]
Calculate the sum or difference
[tex]-0.5x=-7.5[/tex]
Divide both sides of the equation by the coefficient of variable
[tex]x=\frac{-7.5}{-0.5}[/tex]
Determine the sign for multiplication or division
[tex]x=\frac{7.5}{0.5}[/tex]
Multiply both the numerator and denominator with the same integer
[tex]x=\frac{75}{5}[/tex]
Cross out the common factor
[tex]x=15[/tex]

The scale on a map shows that 1 inch = 30 miles. If there are 4.5 inches between your present location and the place you want to go, how many miles do you have to ?
Scale : 1 inch = 30 miles
So, the ratio between the distance on the map and the real distance is 1:30
When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.
Call the miles we have to go : x
1:30 = 4.5:x
(1x4.5):(30x4.5) = 4.5 : x
4.5 : 135 = 4.5 : x
So, x = 135 => We have to go 135 miles to get to the place we want to go.

A prism is dilated by a factor of 1. 5. How many times larger is the volume of the resulting prism than the volume of the original prism? Enter your answer as a decimal in the box.
The volume of the resulting prism is 3.375 times of original volume.
What is a dilation or scale factor?The factor by which the dimensions of an object are enlarged is called the scale factor.
Let us take the base area of Prizm = a²
Height of the prism = h
Enlarged area = (scale factor)² * previous area
Enlarged area = 1.5²*a² = 2.25a²
Enlarged height = 1.5h
So, enlarged volume = enlarged area* enlarged height
Enlarged volume= 2.25a²*1.5h = 3.375a²h
Enlarged area/previous area = 3.375a²/a² = 3.375
Therefore, the volume of the resulting prism is 3.375 times of original volume.

ANSWER

The required coordinates of point B is (-6.5, 0), therefore option a is correct.
To find the coordinates of point B, we can use the midpoint formula. The midpoint formula states that the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂) is given by:
Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)
In this case, point A is given as (1/2, 6) and the center of the circle is at (-3, 3). Let's denote the coordinates of point B as (x, y). Since the center of the circle is the midpoint of the diameter AB, we can set up the following equation:
Midpoint = ((1/2 + x) / 2, (6 + y) / 2) = (-3, 3)
Now, let's solve for x and y:
1/2 + x = -6
x = -6 - 1/2
x = -6.5
6 + y = 6
y = 6 - 6
y = 0
So, the coordinates of point B are (-6.5, 0).
Therefore, the correct answer is an option: a-(-6.5, 0).

(b) -6, -2
(c) negative
(d) 5
Step-by-step explanation:
(a) A function is "decreasing" when the y-value decreases as the x-value increases.
⇒ the function is decreasing over these intervals : (-∞, -8) (-6, -4) (-2, ∞)
(b) Local maxima are the points on the function where it reaches a maximum.
⇒ maxima at x = -6 and x = -2
