Answer:
Step-by-step explanation:
Area of the semicircle = pi * r^2 / 2
d = 8
r = d/ 2
r = 8/2 = 4 inches
Area = pi * 4^2 / 2
Area = 3.14 * 8
Area = 25.12 square inches
Area of the triangle
Area = 1/2 * b * h
b = 8
h = 3
Area = 1/2 * 8 * 3
Area = 12 square inches
Total area = 25.12 + 12
Total area = 37.12 square inches

Given the diagram below find the value of x
Answer:
x = 15
Step-by-step explanation:
a straight line has the angle of 180 degrees
so when added together both angles should equal 180
4x - 17 + 137 = 180
then combine like terms
4x + 120 = 180
and then subtract
4x = 60
and then divide
x = 15
and that is your answer
Enter the equation of the line in slope-intercept form.
Slope is -3, and (4,3) is on the line.
The equation of the line is y =
The slope intercept formula y= mx+b .
y= mx+b
We already know the slope which is -3 and plugin 4 for x and 3 for y. Here we are trying to find the y-intercept which is b.
3= -3(4)+b
3= -12+b
+12 +12
15 = b
Here is how it is written in slope- intercept form:
y= -3x+15
A tractor can plant a field at a rate of 2.5 acres per 5 minutes. If a mammoth farm measuring 4 square miles needs planting, how long will it take in hours to plant the field? There are 640 acres in a square mile. Determine your answer to the nearest hour. If the tractor can run 8 hours a day, what is the minimum number of days it will take to plant the farm?
The time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The minimum number of days taken by the tractor when working 8 hours a day is 11 days.
What is the area?The area is the total surface occupied within the boundary of the figure.
How to solve the question?In the question, we are given that a tractor can plant a field at a rate of 2.5 acres per 5 minutes.
We are asked the time taken by the tractor to plant a field having an area of 4 square miles.
First, we convert the area of the field from sq. miles to acres using the conversion rate, 1 square mile = 640 acres,
Thus, the area of the field = 4 sq. miles = 4*640 acres = 2560 acres.
Time taken to plant 2.5 acres is given to be 5 minutes.
Thus, the time taken to plan 1 acre = 5/2.5 = 2 minutes.
Thus, the time taken to plant the field having an area of 2560 acres = 2560*2 minutes = 5120 minutes = 85.33 hours = 85 hours and 20 minutes.
Thus, the time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The time for which the tractor can run daily is 8 hours.
Thus, the number of days taken by the tractor to plant the field = 85.33/8 = 10.66625, or 11 days.
Thus, the minimum number of days taken by the tractor when working 8 hours a day is 11 days.

Liam invests $3,670 in a savings account at his local bank which gives 1.9% simple annual interest. He also invests $2,040 in an online savings account which gives 5.5% simple annual interest. After five years, which one will have earned more interest, and how much more interest will it have earned, to the nearest dollar?
Step-by-step explanation:
Given:
Investment P₁ = $3670Investment P₂ = $2040Rate of interest r₁ = 1.9% SIRate of interest r₂ = 5.5% SITime t = 5 yearsFind amount of interest in both investments:
I₁ = P₁r₁t = $3670*(1.9/100)*5 = $348.65I₂ = P₂r₂t = $2040*(5.5/100)*5 = $561.00As we see the online savings account earns more interest and the difference is:

True of False? The blue radius is perpendicular to the green chord
Answer:
Step-by-step explanation:
true i think
The statement that the blue radius is perpendicular to the green cord is false.
What are radius and chords?The radius of a circle is any line segment connecting the centre of the circle to any point on the circle. The chord of a circle is a line segment joining any two points on the circle.
From the complete question,
The blue radius does not bisect the green chord
This means that the blue radius and the green chord do not meet at 90 degrees
Since both lines do not meet at 90 degrees, then they are not perpendicular
Hence, the statement that the blue radius is perpendicular to the green cord is false

If 20% of a number is 28 and 25% of the same number is 35, find 45% of that number.If 7% of a number equals 9, find 70% of that number.
Answer:
Step-by-step explanation:
Let the number be 'x'
20% * x = 28
[tex]\dfrac{20}{100}*x = 28\\\\\\\dfrac{1}{5}*x=28\\\\\\x=28*5\\\\x = 140[/tex]
[tex]\dfrac{45}{100}*140=9*7=63[/tex]
45% of 140 = 63
2)
[tex]\dfrac{7}{100}*y=9\\\\y=9*\dfrac{100}{7}=\dfrac{900}{7}=128.57[/tex]
[tex]\dfrac{70}{100}*128.57= 90[/tex]

1) quotient of 32 and 4 is 32/4
8 more than means + 8
so 32÷4 + 8
2) quotient of 12 and 6 is 12/6
8 more than means + 8
so 12÷6 + 8
3) 7 * 4 + 3
here multiplication gets preference
so it is (7*4) + 3
3 more than the product of 7 and 4
4) 35 ÷ (12 - 5)
here parentheses gets preference
so it can be called as
35 divided by the difference of 12 and 5
or the quotient of 35 and the difference of 12 and 5
5) fill the boxes as below
16 divided by 4 = 16 ÷ 4
