Answer:
50.90 cm
Step-by-step explanation:
The computation of the circumference of this circle is shown below:
As we know that
The circumference of this circle is
= 2πr
where
π is 3.142
r = diameter ÷ 2
= 16.8 ÷ 2
= 8.1 cm
So, the circumference of the circle is
= 2 × 3.142 × 8.1 cm
= 50.90 cm

Drew has 4 pieces rope 1 meter long each. He cuts each rope into fifths. How long will each of the fifths be in centimeters?
Answer:
20 CM
Step-by-step explanation:
100 cm = 1 meter
the one meter roope = 100cm
Dvide 100cm by 1/5 to determine the length of each cm
100 cm x 5 = 20
100 cm x 5
A trader bought 40 shirts for Birr 220 and sold them at Birr 72 each
Find the profit percentage.
Given:
Cost price of 40 shirts = Birr 220
Selling price of each shirt = Birr 72
To find:
The profit percentage.
Solution:
We have,
Cost price (CP) of 40 shirts = Birr 220
Selling price (SP) of each shirt = Birr 72
So, the selling price (SP) of 40 shirts is:
[tex]72\times 40=2880[/tex]
We need to find the profit percentage.
[tex]\text{Profit percentage}=\dfrac{SP-CP}{CP}\times 100[/tex]
[tex]\text{Profit percentage}=\dfrac{2880-220}{220}\times 100[/tex]
[tex]\text{Profit percentage}=\dfrac{2660}{220}\times 100[/tex]
[tex]\text{Profit percentage}=1209.09\%[/tex]
Therefore, the profit percentage is 1209.09%.
If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tenth.
Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
A map uses a scale of 3/4 in = 80 miles. If two buildings are 60 miles apart in real life, how far apart would they be drawn on the map?
Given:
The scale of a map is [tex]\dfrac{3}{4}\ in=80\ miles[/tex].
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,
[tex]\dfrac{3}{4}\ in=80\ miles[/tex]
It means, 80 miles in real life = [tex]\dfrac{3}{4}\ in[/tex] on the map.
1 mile in real life = [tex]\dfrac{3}{4\times 80}\ in[/tex] on the map.
60 mile in real life = [tex]\dfrac{3\times 60}{4\times 80}\ in[/tex] on the map.
= [tex]\dfrac{180}{320}\ in[/tex] on the map.
= [tex]\dfrac{9}{16}\ in[/tex] on the map.
Therefore, the buildings are [tex]\dfrac{9}{16}\ in[/tex] apart on the map.

Janice bought 3 hamburgers and 4 hotdogs for her cousins and paid $8.50. Brian bought 3 hamburgers and 6 hotdogs for his cousins and paid $10.50. How much did one hamburger cost?
A) 2.00
B) 1.50
C) 1.00
D) 0.75
Answer:
Cost of each hamburger = $1.50
Step-by-step explanation:
Given:
Cost of 3 hamburger and 4 hotdog = $8.50
Cost of 3 hamburger and 6 hotdog = $10.50
Find:
Cost of each hamburger
Computation:
Cost of each hamburger = h
Cost of each hotdog = d
So,
3h + 4d = 8.50.....EQ1
3h + 6d = 10.50.......EQ2
EQ2 - EQ1
2d = 2
d = 1
3h + 4d = 8.50
3h + 4(1) = 8.50
3h = 4.50
h = 1.50
Cost of each hamburger = $1.50
Graph the following features: Slope = 1/3 Y-intercept = 3
Answer:
The answer is in the photo.
Step-by-step explanation:
Start by putting a dot on (0,3). Then go up one and to the right three, and that will be your next dot and then just go from there and keep going up one and to the right three. Then to get the other half of your graph you will do the opposite by going down one and to the left three.
The equation of the line that has a slope of (1/3) and the y-intercept of 3 will be 3y = x + 9.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is 1/3 and the y-intercept of the line is 3. Then the equation of the line is given as,
y = (1/3)x + 3
Simplify the equation, then we have
y = (1/3)x + 3
y = (x + 9) / 3
3y = x + 9
The condition of the line that has an incline of (1/3) and the y-block of 3 will be 3y = x + 9. The graph of the line is given below.

y = x/7 -18 What is the value of y when x = 133?
*Please show work. (Is not mandatory but try to*
Answer:
1
Step-by-step explanation:
(133)/7 - 18
133 ÷ 7 = 19
19 - 18 = 1
Answer: y = 1
Step-by-step explanation:
Well if x is 133 then the problem is y = (133/7) -18
and 133/7 is 19
so the problem is y = 19 - 18
and 19 - 18 is 1, so
y = 1

Madeline invests $25,000 in an account that offers a compound interest rate
of 9.5% per year. Which of the following is the correct equation for how much
Madeline will have after 8 years?
The correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex].
What is compound interest ?Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
We have,
Principal [tex]=\$25,000[/tex]
Rate[tex]=9.5\%[/tex]
Time [tex]=8[/tex] years
Now,
Using the above mentioned formula,
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
[tex]=25000(1+\frac{9.5}{100})^8[/tex]
Amount [tex]=25000(1+0.095)^8[/tex]
So, the equation for final amount is [tex]25000(1+0.095)^8[/tex].
Hence, we can say that the correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex] .
