Answer: D: 65
Step-by-step explanation:
A nickel is worth 5 cents (which we will write as 0.05).
A quarter is worth 25 cents (which we will write as 0.25).
65 X 0.05 = $3.25.
35 X 0.25 = $8.75
$3.25 + $8.75 = $12

Adrian and Brian are brothers. They leave the house on their bicycles and head to school that is a distance of 4 km away. Adrian cycles 1 km/hour faster than Brian and arrives to school 1 minute earlier. Algebraically determine the speeds of each brother
Answer:
Brian's rate is 15 km/hr
Adrian's rate is 16 km/hr
Step-by-step explanation:
Let r = Brian's rate
r + 1 = Adrian's rate
4/r = Brian's time
4/(r + 1) = Adrian's time
The difference in times is 1 min = 1/60 hr
[tex]\frac{4}{r} - \frac{4}{r + 1} = \frac{1}{60}[/tex] LCD = 60r(r + 1)
4(60)(r + 1) - 4(60)r = r(r + 1)
240r + 240 - 240r = [tex]r^{2}[/tex] + r
[tex]r^{2}[/tex] + r - 240 = 0
(r - 15)(r + 16) = 0
r = 15 or r = -16
Since the rate cannot be negative, Brian's rate is 15 km/hr and Adrian's rate is 16 km/hr
Which expression is equivalent to (8x-4)+(5-4x)
Answer:
4x + 1
Step-by-step explanation:
Combine like terms, or terms with the same amount of the same variable:
(8x - 4) + (5 - 4x) =
(8x - 4x) + (5 - 4) = 4x + 1
4x + 1 is your answer.

AD and MN are chords that intersect at point B.
A circle is shown. Chords A D and M N intersect at point G. The length of A B is 9, the length of B D is x + 1, the length of M B is x minus 1, and the length of B N is 15.
What is the length of line segment MN?
Answer:
[tex]MN = 18[/tex]
Step-by-step explanation:
Given
[tex]AB = 9[/tex]
[tex]BD = x + 1[/tex]
[tex]MB = x - 1[/tex]
[tex]BN = 15[/tex]
See attachment
Required
Determine MN
The products of the segments of two chords that intersect are always, equal.
So, we have:
[tex]AB * BD = MB * BN[/tex]
[tex]9 * (x + 1) = (x - 1) * 15[/tex]
Open bracket
[tex]9x + 9 = 15x - 15[/tex]
Collect like terms
[tex]15x - 9x = 9 + 15[/tex]
[tex]6x = 24[/tex]
Solve for x
[tex]x = \frac{24}{6}[/tex]
[tex]x = 4[/tex]
The length of MN is calculated as:
[tex]MN = MB + BN[/tex]
[tex]MN = x - 1 + 15[/tex]
Substitute [tex]x = 4[/tex]
[tex]MN = 4 - 1 + 15[/tex]
[tex]MN = 18[/tex]

What fraction of the time did Snowy Pines get at least 14 inches of snow?
Answer:1/4
Step-by-step explanation:
I got it right.
Fraction of time that the Snowy Pines get at least 14 inches of snow is 1/4.
What is Box Plot?Box plot, which is also known as box and whisker plot, is a method of graphically representing the measures like minimum, maximum and the quartiles of the data set.
Given is a box and whisker plot.
We know that box plot represents the first quartile, median and third quartile of the data set.
First quartile is where the 25% of the data points lie.
Median is where the 50% of the data points lie.
Third quartile is where 75% of the data points lie.
Above 14 inches lie the third or upper quartile.
75% of the data points lies below 14.
Data points which are at least 14 inches is 14 or more than 14.
Snowy Pines get at least 14 inches of snow for 100% - 75% = 25% of data points.
Fraction = 25/100 = 1/4
Hence the required fraction of time is 1/4.

Gabe has a great job. He earns money on an hourly basis and he was given a signing bonus to switch jobs. He forgot how much they said they would pay him by hour but on his time card he has at 4 hours he has earned 1,120 and at 10 hours he has earned 1,480. What is an equation that will model this situation? How much money will he earn in a 40 hour work week?
Answer:
Pay for 40 hours would be [tex]\geq 40 * 148[/tex]
Step-by-step explanation:
Gabe works for 4 hours and earns $ 1,120
Pay for one hour is [tex]\frac{1120}{4} = 280[/tex]
When he works for 10 hours, he earns $1480.
Pay for one hour is
[tex]\frac{1480}{10} = 148[/tex]
Thus the per hours pay must be greater than or equal to 148 dollars
Pay for 40 hours would be [tex]\geq 40 * 148[/tex]

Jillian is making a paper flower motif for an art project the flower she is making has 4 petals each petal is made of three semicircles as shown below, What is the area of the paper flower?
Answer:
[tex]Area = 216\pi[/tex]
Step-by-step explanation:
Given
See attachment for semicircles
Required
The area of the paper
First, calculate the area of each petal.
The petal is made up of:
1. Semicircle of diameter 12cm
2. Semicircle of diameter 18cm (i.e. 12cm + 6cm)
3. A hole semicircle of diameter 6cm
The area of each semicircle is calculated as follows:
[tex]Area = \frac{\pi r^2}{2}[/tex]
For (1):
[tex]d = 12cm[/tex] --- diameter
[tex]r = 0.5 * d = 0.5* 12cm = 6cm[/tex] --- radius
So:
[tex]A_1 = \frac{\pi * 6^2}{2}[/tex]
Evaluate the exponent
[tex]A_1 = \frac{\pi * 36}{2}[/tex]
Divide 36 by 2
[tex]A_1 = 18\pi[/tex]
For (2):
[tex]d = 18cm[/tex]
[tex]r = 0.5* 18cm = 9cm[/tex]
So:
[tex]A_2 = \frac{\pi * 9^2}{2}[/tex]
[tex]A_2 = \frac{\pi * 81}{2}[/tex]
[tex]A_2 = 40.5\pi[/tex]
For (3):
[tex]d = 6cm[/tex]
[tex]r = 0.5* 6cm = 3cm[/tex]
So:
[tex]A_3 = \frac{\pi * 3^2}{2}[/tex]
[tex]A_3 = \frac{\pi * 9}{2}[/tex]
[tex]A_3 = 4.5\pi[/tex]
Recall that (3) is a hole.
So, the area (A) of a petal is:
[tex]A = A_1 + A_2 - A_3[/tex]
[tex]A = 18\pi + 40.5\pi - 4.5\pi[/tex]
[tex]A = 54\pi[/tex]
The paper uses 4 petals.
So:
[tex]Area = 4 * A[/tex]
[tex]Area = 4 * 54\pi[/tex]
[tex]Area = 216\pi[/tex]

What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
2x2+ 40 = -8x
Answer:
Step-by-step explanation:
Simplify this problem by dividing all three terms by 2:
x^2 + 20 = -4x
Rewrite this in standard form:
x^2 + 4x + 20
Take the coefficient of the x term and divide it by 2: 4/2 = 2
Square this result: 2^2 = 4
Between x^2 + 4x and 20 add this 4, then subtract it:
x^2 + 4x + 4 - 4
Rewrite x^2 + 4x + 4 as the square of a binomial:
(x + 2)^2 - 4, or (x + 2)^2 = 4

Jerry also has a plastic cylinder to use for building the sandcastle. The cylinder has the same radius and the same height as the cone. What is the volume of the cylinder?
Use ≈3.14 and round your answer to the nearest whole number.
cubic inches
Complete the sentence below that describes the relationship between the volumes of the cone and cylinder. Use a whole number.
The cone and cylinder have the same height and radius, so the volume of the cylinder is
times the volume of the cone.
Answer:
155in³, 465in³
The cone and cylinder have the same height and radius, so the volume of the cylinder is 3 times the volume of the cone.
Step-by-step explanation:
Formula: πr²[tex]\frac{h}{3}[/tex]
Given: π = 3.14, r = 4.6, h = 7
Sub: 3.14(4.6)²[tex]\frac{7}{3}[/tex]
SImplify: 3.14(21.16)[tex]\frac{7}{3}[/tex]
Simplify: (66.4424)[tex]\frac{7}{3}[/tex]
Solve: 155
The volume of the cone is 155in³
Formula: (πr²)h
Given: π = 3.14, r = 4.6, h = 7
Sub: (3.14(4.6²))7
Simplify: (3.14(21.16))7
Simplify: (66.4424)7
Solve: 465
The volume of the cylinder is 465.
Since the last term of the cone is 1/3 of the last term of the cylinder, we can say:
The cone and cylinder have the same height and radius, so the volume of the cylinder is 3 times the volume of the cone.

(a) Anne, Barry and Colin share a prize in the ratio 3:4:5.
Colin gives 1/3 of his share to a charity.
What fraction of the whole prize does Colin give to the charity
Answer: 1/12
Step-by-step explanation:
1. Add up the 3 parts making 12
3:4:5 = 3+4+5=12
2. Out of the ratio we know that Colin gets 5 parts which is 5/12
3. If we subtract 5/12 from 1/3 we should get an answer of 1/12
5/12-1/3 =1/12
