Answer:
1) 0.9 as fraction is: [tex]\mathbf{\frac{9}{10}}[/tex]
2) Solve for c =4 for the equation [tex]2 \times (c^2-5)[/tex] we get 22
3) t = 64
4) p=3.15
5) Volume of Cuboid = 160 m³
6) x =9
Step-by-step explanation:
1) Write as fraction: 0.9
For writing the fraction, Since we have decimal point at tent's place so we can write it as: [tex]\frac{9}{10}[/tex]
So, 0.9 as fraction is: [tex]\mathbf{\frac{9}{10}}[/tex]
2) Solve for c =4
[tex]2 \times (c^2-5)[/tex]
Put c = 4 and find the answer
[tex]2 \times (c^2-5)\\Put\:c=4\\=2\times ((4)^2-5)\\=2\times (16-5)\\=2\times(11)\\=22[/tex]
So, Solve for c =4 for the equation [tex]2 \times (c^2-5)[/tex] we get 22
3) [tex]\frac{t}{4}=16[/tex]
We need to find value of t
Multiply both sides by 4
[tex]4\times\frac{t}{4}=16\times 4\\t=64[/tex]
So, we get t = 64
4) [tex]2.4p=7.56[/tex]
We need to find value of p
Divide both sides by 2.4
[tex]\frac{2.4p}{2.4}=\frac{7.56}{2.4}\\p=3.15[/tex]
So, we get p=3.15
5) Find Volume of Cuboid
The formula used is: [tex]Volume\:of\: Cuboid=Length\times Breadth \times Height[/tex]
We have Length = 4, Breadth = 8 and Height = 5
Putting values and finding volume:
[tex]Volume\:of\: Cuboid=Length\times Breadth \times Height\\Volume\:of\: Cuboid=4\times 8 \times 5\\Volume\:of\: Cuboid=160[/tex]
So, Volume of Cuboid = 160 m³
6) [tex]3x=27[/tex]
We need to find value of x
Divide both sides by 3
[tex]3x=27\\\frac{3x}{3}=\frac{27}{3}\\x=9[/tex]
We get x =9

The staff takes 1/2 of an hour to assemble 1/8 of the booths. How long does it take the staff to assemble all of the booths?
Answers
Answer:
It takes all staff 3 hours
Step-by-step explanation:
So, first we write down all these important info. It takes half hour for staff to assemble one sixth (1/6) of the booths. First you need to take the fraction 1/6 a whole number by multiplying it by the denominator which in this case is 6 which will give you the answer 1. Next, you do the exact same thing for the other part. Multiply 1/2 by 6 to get 3.
The time to assemble the remaining fraction of the bottle is 3.5 hours.
Time to assemble one-eight of the bottles
The time taken for the staff to assemble one - eight (1/8) of the bottles is given as half (1/2) hour.
Remaining fractionThe remaining fraction of the bottle is calculated as follows;
[tex]= 1 - \frac{1}{8} \\\\= \frac{7}{8}[/tex]
Time to assemble the remaining fraction of the bottlesThe time to assemble the remaining fraction of the bottle is calculated as follows;

Find the length of the shortest side if the area of the rectangle is 144m2
х
x + 10
Answers
Answer:
Given,
Length and breadth of the rectangle are (x) and (x+10)
Area of the rectangle ( A ) = 144[tex]m^{2}[/tex]
We know ,
Area of rectangle ( A ) = L*B
or , 144 = x ( x+10 )
or , 144 = [tex]x^{2}[/tex] + 10x
or , [tex]x^{2}[/tex] + 10x - 144 = 0
Solving the equation , we get ,
x = 8 and -18
The side has to be positive so ,
x = 8 m , which is the shortest side !
Step-by-step explanation: We were given the area of the rectangle and length & breadth in expression . By using the formula of area of rectangle , we got the equation which then gave 8 and -18 as answers when solved and since the rectangle had positive sides 8 m was the correct value . Also its the shortest side and the other side is simply ( 8 + 10 ) which is 18 m but the question has only asked for the shortest side !
The bike store marks up the wholesale cost of all of the bikes they sell by 30%.
Andre wants to buy a bike that has a price tag of $125. The wholesale cost of this bike was $87.50.
Answers
Answer:
Suppose that the wholesale of a bike is A (A is the 100% in this case). If we have an increase of 30% for the sale price, we have the new price of:
Price = A + (30%/100%)A = A + 0.3*A = (1.3)*A
Then if we know that the price tag of the bike is $125, then we have:
$125 = (1.3)*A
$125/1.3 = A = $96.15
The wholesale cost of the bike is $96.15
Answer:
1. Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike? $ 96.15
2. If the bike is discounted by 20%, how much will Andre pay (before tax)?

Answer:
The radius, in inches, of the base of the cone will be:
r = 6 inches
Hence, option B is correct.
Step-by-step explanation:
Given
The Volume of a right circular cone V = 24 π cubic inches
The height of the cone h = 2 inches
To determine
The radius of the base of the cone r = ?
Using the formula involving Volume m, height h, and radius r of a right circular cone.
[tex]V\:=\frac{1}{3}h\:\pi \:\:r^2\:[/tex]
substituting V = 24 π, h = 2 to find the radius r
[tex]\left(24\pi \right)=\frac{1}{3}\left(2\right)\:\pi \:r^2[/tex]
switch sides
[tex]\frac{1}{3}\left(2\right)\pi r^2=\left(24\pi \right)[/tex]
[tex]\frac{1}{3}2\pi r^2=24\pi[/tex]
simplify
[tex]2\pi r^2=72\pi[/tex]
Divide both sides by 2π
[tex]\frac{2\pi r^2}{2\pi }=\frac{72\pi }{2\pi }[/tex]
[tex]r^2=36[/tex]
[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
[tex]r=\sqrt{36},\:r=-\sqrt{36}[/tex]
Thus,
[tex]r=6,\:r=-6[/tex]
As we know that the radius can not be negative.
Therefore, the radius, in inches, of the base of the cone will be:
r = 6 inchesHence, option B is correct.

The figure pictured contains two congruent triangles (ASA), so we can assume that:
JK ≅ JM
Therefore:
2x - 4 = 4x - 16
Subtract 2x from both sides:
2x - 2x - 4 = 4x - 2x - 16
-4 = 2x - 16
Add 16 to both sides:
-4 + 16 = 2x - 16 + 16
12 = 2x
Divide both sides by 2:
12/2 = 2x/2
x = 6.

What is the annual (yearly) rate of interest?
d) 9%
a. 36%
b. 4.8 %
c. 7%
Answers
Answer:
1. a. 2,000
2. b. 10 years
3. a. 6.72937
4. d. 9%
Step-by-step explanation:
1. If 58% are boys, the percentage of girls is:
= 100 - 58
= 42%
That means 840 is 42% of the students in class. The students in class are therefore:
= 840 / 42%
= 2,000 students
2. If Birr 300 is invested at 6% per year, the amount in interest it earns per year is:
= 300 * 6%
= Birr 18
To get to Birr 180, it would take:
= 180/18
= 10 years
3. When a number is in percentage that means that it is a fraction with the denominator being 100. The number is decimal will therefore be it divided by 100:
= 672.937/100
= 6.72937
4. The investment accrued Birr 12 out of Birr 400 in 4 months. This means that it increased by:
= 12/400
= 3%
A year can be divided into three by 4 months. This means that the yearly rate is therefore:
= 3% * 3
= 9%

Evelyn is working two summer jobs, making $18 per hour lifeguarding and making $11 per hour tutoring. In a given week, she can work a maximum of 15 total hours and must earn no less than $200. If Evelyn worked 8 hours lifeguarding, determine the maximum number of whole hours tutoring that she can work and still meet her requirements. If there are no possible solutions, submit an empty answer.
Answers
Answer:
Evelyn can work a maximum of [tex]7[/tex] hours tutoring.
Step-by-step explanation:
Evelyn earns [tex]\$\: 18[/tex] per hour lifeguarding and she worked [tex]8[/tex] hours lifeguarding.
So, total money earned by lifeguarding [tex]=\$\: 18\times 8=\$\:144[/tex].
She must earn no less than [tex]\$\:200[/tex].
So, money left to earn [tex]=\$\: 200-\$\:144=\$\:56[/tex].
Evelyn worked [tex]8[/tex] hours lifeguarding. She can work a maximum of [tex]15[/tex] total hours. So, she can work [tex]15-8=7[/tex] hours.
Evelyn earns [tex]\$\: 11[/tex] per hour tutoring.
So, total money earned by tutoring [tex]=\$\: 11\times 7=\$\:77[/tex].
Therefore, the total money earned [tex]=\$ \:144+\$\:77=\$\:221[/tex].
Hence, Evelyn can work a maximum of [tex]7[/tex] hours tutoring.

A kite consists of two pairs of congruent adjacent sides. Therefore, we have the following equation:
[tex]2x+2(4x-8)=78[/tex], where [tex]x[/tex] is the length of the shorter sides.
Solving, we get:
