3/500% of a quantity is equal to what fraction of the quantity?
what is the answer??????
Answer:
3/5
Step-by-step explanation:
Given
[tex]\frac{3}{500} \%[/tex]
Required
Represent as fraction
To do this, we simply multiply 3/500 by 100
[tex]\frac{3}{500} \% = \frac{3}{500} * 100[/tex]
[tex]\frac{3}{500} \% = \frac{3}{5}[/tex]
So, the fraction is 3/5

Find angle. Picture below
Answer:
x+3x+90=180(sum of angle of triangle)
4x=180-90
x=90/4=22.5
m<T=3×22.5=67.5°
m<v=22.5°
Answer:
Step-by-step explanation:
By angle sum of triangle:
3x+x+90=180
x=22.5
Angle T = 3x=3(22.5)=67.5
Angle V = x = 22.5

Carpet is installed in the hallways of a building. The cost of carpet and installation is $32.50 per square yard. A total length of 432.0 feet of carpet 5.0 feet wide is required. What is the total cost of carpet and installation? (Number of square feet = length in feet × width in feet)
Answer:
[tex]Total = \$7800[/tex]
Step-by-step explanation:
Given
[tex]Cost = \$32.50[/tex] per square yard
[tex]Length = 432.0ft[/tex]
[tex]Width = 5.0ft[/tex]
Required
Determine the cost of carpet and installation
First, calculate the area of the carpet
[tex]Area = Length * Width[/tex]
[tex]Area = 432.0ft * 5.0ft[/tex]
[tex]Area = 2160ft^2[/tex]
Convert to square yard
[tex]Area = \frac{2160yd^2}{9}[/tex]
[tex]Area = 240yd^2[/tex]
The cost is then calculated as:
[tex]Total= Area * Unit\ Cost[/tex]
[tex]Total = 240 * \$32.50[/tex]
[tex]Total = \$7800[/tex]

Zachary invested $700 in an account paying an interest rate of 4.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $1,360?
Answer:
14
Step-by-step explanation:
The nearest time period for Zachary to reach the amount is 14 years.
What is compound interest?
Compound interest is the interest on a deposit or loan calculated based on the initial principle, and the collective interest from previous periods.
For the given situation,
Principle, [tex]p=\$700[/tex]
Interest rate, [tex]r=4.9\%[/tex][tex]=0.049[/tex]
Amount, [tex]a=\$1360[/tex]
Compounded continuously, [tex]n=1[/tex]
We have to find the time period, [tex]t[/tex]
The amount formula of compound interest, [tex]a=p(1+\frac{r}{n} )^{nt}[/tex]
On substituting the values,
[tex]1360=700(1+\frac{0.049}{1} )^{1t}[/tex]
Divide by [tex]700[/tex] on both sides,
⇒[tex]\frac{1360}{700}=\frac{700}{700} (1+0.049 )^{t}[/tex]
⇒[tex]1.94=(1.049)^{t}[/tex]
Taking log on both sides,
⇒㏒[tex]1.94[/tex]=[tex]t[/tex]㏒[tex]1.049[/tex]
⇒[tex]0.28=0.020t[/tex]
Divide by [tex]0.020[/tex] on both sides,
⇒[tex]\frac{0.28}{0.020}=t[/tex]
⇒[tex]t=14[/tex]
Hence, the time period is 14 years.

A college basketball player makes 70% of his free throws. At the end of a game, his team is losing by two points. He is fouled attempting a three-point shot and is awarded three free throws. Assuming each free throw is independent, what is the probability that he makes at least two of the free throws?
a. 0.784
b. 0.700
c. 0.216
d. 0.441
Answer:
B.
Step-by-step explanation:
If he makes 70% then 70% as a decimal would be 0.700 which is B
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability that he makes at least two of the free throws is 0.0700.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head when a coin is tossed is 1/2
We have,
Each free throw is independent of the other.
Percentage of making free throws = 70%
The probability that he makes at least two of the free throws.
= 70%
= 70/100
= 0.07
This can be written as 0.0700.
Thus,
The probability that he makes at least two of the free throws is 0.0700.

Answer:
In two weeks she eats 28 pieces
Step-by-step explanation
Lets say she ate one per day, if its asking you how many you ate in two weeks, that would be 14 candies. But if she ate 2 per day all you have to do is add 14+14 to find out how many she ate in two weeks.
Answer:28 candies
Step-by-step explanation:
So Chrissy eats 2 each day and we need to find how many candies she eats in two weeks also in weeks there is 7 days plus another week would be 14 basically convert the 2 weeks into days (7+7).Now we need multiply since she eats 2 each day how many candies she eats in two weeks also in week so 2 x 14 =28
Verified answer!Therefore,she eats 28 candies in 2 weeks
