Chloe invests money in an account paying simple interest. She invests $200 and no money is added or removed from the investment. After one year, she has $204. What is the simple percent interest per year?
Answers
Answer:
2%
Step-by-step explanation:
Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.
$204 - $200 = $4Now that we know the simple interest, we can now get the simple interest rate or simple percent interest per year by dividing $4 by $200.
$4 ÷ $200 = 0.02Let's change 0.02 into a percentage.
0.02 x 100 = 2%This means that every year, her investment will earn a 2% simple interest.
Answer:
2%

Answers
Answer:
The ratio of the diameter of ball A to the diameter of ball B is 10:19.
Step-by-step explanation:
Ratios
A ratio is a relation between two quantities and it's calculated as a division. For example, the ratio between 8 and 4 is 8:4 = 8 / 4 = 2.
We are given the diameters of two balls as follows:
The diameter of the ball A=30mm
The diameter of the ball B=5.7 cm = 57 mm
The ratio of the diameter of ball A to the diameter of ball B is 30:57. Dividing both numbers by 3, we have: ratio=10:19
The ratio of the diameter of ball A to the diameter of ball B is 10:19.

Answers
Answer:
The distinction between statistical significance and practical importance is best illustrated by:
C. In 50,000 births, the new vaccine reduced the incidence of infant mortality in Morrovia significantly from 14.2 deaths per 1000 births to 10.3 deaths per 1000 births.
Step-by-step explanation:
Current state Previous state Change
A. Textbooks sold 240/400 (0.6) 220/330 (0.67) 0.07
B. Life of hard disk 250,000 hrs 240,000 hrs 0.04
C. Infant mortality 10.3 per 1000 14.2 per 1000 0.27
D. Cruising range 4,000 miles 3,975 miles 0.006
Statistical significance, which depends on the p-value established before the test, relates to whether an effect exists, while practical significance determines the magnitude or size of the effect. A statistical test cannot tell whether the magnitude is large enough to be important. Mathematically, the change can be determined, which establishes the practical significance or importance of the change.
Find the volume of the solid generated by revolving the region bounded by the graphs of the equations and inequalities about the y-axis.x2 - y2 = 64, x \geq 0, y = -8, y = 8
Answers
Answer:
The Volume of the solid
V = π(1365.33) cubic units
Step-by-step explanation:
Step(I):-
Given curves are x²- y² = 64 , x=0 , y=-8 and y=8
The given function x = f(y)
x²- y² = 64
x² = y² +64
The Volume of the solid generating by revolving the region bounded by the graphs of the equations
[tex]V = \pi \int\limits^a_b {x^2} \, dx[/tex]
Step(ii):-
the limits are y = a = -8 and y = b=8
The Volume of the solid
[tex]V =\pi \int\limits^8_8 {(y^2+64)} \, dx[/tex]
[tex]V = \pi (\frac{y^{3} }{3} + 64 y )_{-8} ^{8}[/tex]
[tex]V = \pi (\frac{(8)^{3} }{3} + 64 (8) - (\frac{(-8)^{3} }{3} +64(-8) )[/tex]
[tex]V = \pi (\frac{(8)^{3} }{3} + 64 (8) - (\frac{(-8)^{3} }{3} +64(-8) ) = \pi (\frac{1024}{3} + 1024)[/tex]
V = π(1365.33) cubic units

Solve for x using the
distributive property.
8(4 + 2x) = 16
Answers
Answer: x=-1
Step-by-step explanation:
Do 8(4) + 8(2x)=16 to use the distributive property. You should get 32+16x=16. Then, subtract 32 from both sides of the equation and you will get 16x=-16. Finally, divide both sides of the equation by 16 and you will get you answer, x=-1. Hope I helped.
= 32 + 16x = 16
= 32-32 +16x = 16-32
= 16x = -16
= 16x/16 = -16/16
= X = -1
So, in conclusion, X = -1
Check:
8(4 + 2(-1)) = 16
= 32 - 16
= 16
Corbin is selling cheese at the farmers’ market. One wheel of cheese has a diameter of 11 inches.

If the 11-inch wheel of cheese costs $21.35, what is the cost per square inch?
Pls help me, I’m desperate lm.ao
its been so long and no one is answering ??? xD
Answers
Answer:
I. 94.99 in²
II. $0.23
Step-by-step explanation:
Given the following data;
Diameter of wheel = 11 inches
[tex] \pi = 3.14[/tex]
Cost of wheel = $21.35
[tex] Radius, r = \frac {diameter}{2} [/tex]
[tex] Radius, r = \frac {11}{2} = 5.5 \; inches [/tex]
Part A
To find the area;
We know that a wheel is circular in nature. Thus, the area of a circle is given by the formula;
[tex] Area, A = \pi r^{2} [/tex]
Substituting into the equation, we have;
[tex] Area, A = 3.14 * 5.5^{2} [/tex]
[tex] Area, A = 3.14*30.25[/tex]
Area, A = 94.99 in²
Part B
To find cost per square inch;
[tex] Cost \; per \; square \; inch = \frac {Cost \; per \; wheel}{Area \; of \; wheel} [/tex]
[tex] Cost \; per \; square \; inch = \frac {21.35}{94.99} [/tex]
Cost per square inch = $0.23
