D. 79%
Step-by-step explanation:
Took the the on USA Test prep
If a point is randomly selected from the rectangular area of the graph, the probability that it will be in the blue region is 79%.
What is the probability?The ratio of the number of favorable outcomes to the total number of outcomes of an event is known as probability.
It is given that, the length=20, the width=10, and the radius of half circle=10.
Calculate the area of the rectangle.
Knows the area of the rectangle is the product of length and width.
So,
[tex]\Rightarrow \text{Area of rectangle}=\text{10}\times \text{20} \\ \Rightarrow \text{Area of rectangle}=200 \\[/tex]
Calculate the area of the half-circle.
Knows the area of the half-circle[tex]=\frac{\pi r^{2} }{2}[/tex].
So,
[tex]& \Rightarrow \text{Area of half circle}=\frac{3.14\times 10\times 10}{2} \\ & \Rightarrow \text{Area of half circle}=\frac{314}{2} \\ & \Rightarrow \text{Area of half circle}=157 \\[/tex]
Calculate the probability that it will be in the blue region.
Knows the formula for the probability, [tex]\text{Probability}\left( \text{Event} \right)=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}[/tex]
So,
[tex]& \Rightarrow \text{Probability}=\frac{\text{157}}{200} \\ & \Rightarrow \text{Probability}=0.78539 \\ & \therefore \text{Probability }\%=79\% \\[/tex]
Thus, the correct answer is an option (D). i.e., 79%.

A number is decreased by 15% and the resulting number is then increased by 20%. That final number is what percent of the original number?
Answer:
The final final number becomes 102 % of the original number
Step-by-step explanation:
Let the initial number be 100
After decreasing 15%, the new number is 100-15% of 100 = 85
The resulting number is then increased by 20%. The new number will be
85 + 20% of 85 = 85 + 17 = 102
The final final number becomes 102/100 * 100 percent of the original number
The final final number becomes 102 % of the original number

he slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the slope is 4 .
Step-by-step explanation:
can i have brainliest
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x - 3 ← is in slope- intercept form
with slope m = 4
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex] , then
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute (4, 8) into the partial equation
8 = - 1 + c ⇒ c = 8 + 1 = 9
y = - [tex]\frac{1}{4}[/tex] x + 9 ← equation of perpendicular line

Tony and Edwin each built a rectangular garden. Tony’s garden is half as long and 6 times as wide as Edwin’s garden. If the area of Edwin’s garden is 400 square feet, what is the area of Tony’s garden?
Answer:
1200 ft²
Step-by-step explanation:
Let's say that Edwin's garden was 400 feet long and 1 foot wide.
If Tony's garden is half as long and 6 times as wide, then we need to divide 400 in half and multiply 1 by 6 to get the dimensions of Tony's garden.
400/2 = 200 ft
1 × 6 = 6 ft
Area of Tony's Garden = 6 x 200 = 1200 ft²

Ana took out a 4-year loan for 7,500 and paid 3.6% simple interest.How much was the total interest on the loan in dollars?
Answer:
I = $ 1,080.00
Step-by-step explanation:
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.6%/100 = 0.036 per year,
then, solving our equation
I = 7500 × 0.036 × 4 = 1080
I = $ 1,080.00
The simple interest accumulated
on a principal of $ 7,500.00
at a rate of 3.6% per year
for 4 years is $ 1,080.00.

Happy Paws charges $20.00 plus $3.50 per hour to keep a dog during the day. Woof Watchers charges $10.00 plus $4.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
Answer:
8 hours
Step-by-step explanation:
Create an equation that sets the costs equal to each other, where h is the number of hours
3.5h + 20 = 4.75h + 10
Solve for h
3.5h + 20 = 4.75h + 10
20 = 1.25h + 10
10 = 1.25h
8 = h
So, it will take 8 hours for the costs to be equal
