The area of the triangle below is 25/12 square centimeters. What is the length of the
base? Express your answer as a fraction in simplest form.
5/3 cm is the height
Answer:
5/2 cm
Step-by-step explanation:
Given that:
Area of triangle = 25/12 cm
Height of triangle = 5/3 cm
Let,
Length of the base = b
Recall :
Area of a triangle = 1/2 * base * height
Substitute the values above into the equation :
25 /12 = 1/2 * b * 5/3
25 /12 = 5b/ 6
Using cross multiplication
25 * 6 = 12 * 5b
150 = 60b
Divide both sides by 60 to isolate b
150/60 = 60b / 60
b = 5/2 cm

(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
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

If (20,8) and (25, 10) belong to a proportional relationship, what is the constant of proportionality
A. 5/2
B. 3/2
C. 1/2
D. 2/5
Answer:
The proportionality constant is 2/5
Step-by-step explanation:
Here, we want to get the proportionality constant
Let us view the two points as being points on a line
The constant of proportionality will be the slope of the line that connects the two points
Mathematically, we can use the formula for the slope of a line
We have this as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (20,8)
(x2,y2)= (25,10)
m = (10-8)/(25-20) = 2/5

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]

It costs $3.50 for 5 pounds of bananas. If the price per pound stays the
same, how much would 4 pounds of
bananas cost?
Answer:
$14.00
Step-by-step explanation:
Here's why. So, if 5 pounds of bananas is $3.50 per pound. All you need to do is do 3.50 * 4 and you'll get your answer, which is $14.00 .
It's pretty easy. If you have a problem like this just multiple the price with the number that they provide you with. :D

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]
