Percent Profit or Loss
Calculate the percentage profit if an antique clock is bought at a yard sale for $20 and sold for $100. Type the number only
Adealer gained a 10% profit by selling an article for birr 330.00 .What was the original price of the article
Answer:
$297
Step-by-step explanation:
Given data
Percent profit=10%
sales price= $330
% profit= (sales price-cost price)/sales price* 100
let the cost price be x
Substitute
10= (330-x)/330* 100
cross multiply
10= (33000-100x)/330
10*330= 33000-100x
3300=33000-100x
3300-33000=-100x
-29700=-100x
29700=100x
x=29700/100
x=297
Hence the cost price is
cost price=$297
A light post is 4 ft tall and cast a shadow of 5 ft. Find the distance between
the top of the post and the end of the shadow.
O 9 ft
O 6.4 ft
O 3 ft
O 4 ft
Answer:
6.4 ft
Step-by-step explanation:
Let “a” be the light post height
Let “b” be the length of the shadow
Let “c” be the distance from the top of the light post to the end of the light post’s shadow.
Then:
(a X a) + (b X b) = c X c
The Pythagorean Theorem will work pretty well here:
(4 X 4) + (5 X 5) = 16 + 25 = 41
The square root of 41 is: 6.4023
So, about 6.4 ft from the top of the post to the end of the shadow
Answer:
6.4ft
Step-by-step explanation:

if y=5 x=9 find m and solve y=m+3x
Answer:
- 22
Step-by-step explanation:
Given
y = 5 and x = 9
then
y = m + 3x
5 = m + 3 * 9
5 = m + 27
m = 5 - 27
m = - 22
hope it helps :)

Which of the following are parallel to
y = 3x – 2
(Choose all that apply)
y = 5 – 3x
Y= 3x
y = 3x – 1
y = 3x – 4
y = -3x
Answer:
y=3x-1,y=3x-4
Step-by-step explanation:
y=mx+c
where is gradient, parallel lines have same gradient
y=5-3x
=-3x+5
m=-3
y=-3x
m=-3
y=3x-1
m=3 ,the gradient is equal to the original equation
y=3x-4
m=3,the gradient also equal to the given equation
Find the perimeter of the figure to the nearest hundredth.
12 in.
5 in.
5 in.
9 in.
perimeter: about
in.
Answer:
50.28 inches
Step-by-step explanation:
From the Image, we can find the length of the arc of the semi-circle by dividing the circumference of the resulting circle by 2
Radius= 9in
C= 2πr
C=2*3.142*9
C=2*3.142*9
C= 56.556 inches
Hence the length of the arc is
=56.556/2
=28.278 inches
The perimeter of the shape
=28.278+5+12+5
=50.28 inches
Answer:
its actualy 50.26, but follow what the guy before me did.

Last Saturday, Emily and Lauren went to the ice cream shop. Enter an expression showing how much they spent together if Emily spent $4.53 and Lauren spent d dollars.
Answer:
With the information provided, you can say that the total amount they spent together would be equal to the result of adding up the amount Emily spent plus the amount Lauren spent, which would be:
Amount Emily spent: $4.53
Amount Lauren spent: d
The expression is:
x=4.53+d, where:
x is the amount they spent together
d is the amount Lauren spent

Ms. Gonzales is investing $17000 at an annual interest rate of 6%
compounded continuously. How much money will be in the account after
16 years? Round your answer to the nearest hundredth (two decimal
places).
Answer:
$30444.41
Step-by-step explanation:
→ Work out compound interest
(100 + 6) ÷ 100 = 1.06
→ Multiply the amount by the money
17000 × 1.06
→ Find how many years it is for
17000 × 1.06¹⁰ = 30444.41
