What is the area of a semicircle that has a radius of 20 feet?
Answer:
[tex]200\pi[/tex] or 628.3185
Step-by-step explanation:
Area of a semicircle is equal to [tex]\frac{\pi r^{2}}{2}[/tex]. So, when the radius is 20, the area of the semicircle will be [tex]\frac{\pi (20)^{2} }{2} =\frac{400\pi }{2} =200\pi =628.3185[/tex].

-2x+2>3x-8
50 points
Given:
The inequality is
[tex]-2x+2>3x-8[/tex]
To find:
The solution of the given inequality.
Solution:
We have,
[tex]-2x+2>3x-8[/tex]
Isolate the variables terms on the left side.
[tex]-2x-3x>-2-8[/tex]
[tex]-5x>-10[/tex]
Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.
[tex]\dfrac{-5x}{-5}<\dfrac{-10}{-5}[/tex]
[tex]x<2[/tex]
Therefore, the correct option is D.

Step-by-step explanation:
The length of two sides of a right triangle are leg: 9 m and hypotenuse: 15 m. Find the length of the third side.
Answer:
Length of Third Side = 12 m
Step-by-step explanation:
You can use the Pythagorean Theorem to solve this: a² + b² = c² or c² - b² = a² in which a and b are legs, and c is the hypotenuse. We use the second equation to solve this: 15² - 9² = a² or 225 - 81 = a². This simplifies to 144 = a². To find a specifically, find the square root of 144, 12.
Hope it helps!

April, x, slept 9 hours; Evelyn slept 2/3
less than that.
Evelyn slept _______________ hours. Write the equation as both a decimal and fraction.
Answer:
she slept for 3 hours
Step-by-step explanation:
its actually simple so we know that April slept for 9 hours bug Evelyn only slept 2/3 of 9 hours and if you add 1/3 and 2/3 you get 3/3 which equals a whole so all you have to do is devide 9 into 3 and you get 3 parts with 3 now you add 3 and 3 together and that equals 6 and that was two parts you added which is equaled to 2/3 so all you have to do now is subtract 9-6 and you leave with three which is 1/3 so we come to the final answer she slept for three hours

Answer:
x = 8
Step-by-step explanation:
EF/EC = EG/ED
21/8x-1 = 17/6x+3
cross-multiply:
21(6x+3) = 17(8x-1)
126x + 63 = 136x-17

Somebody pls!! “Write the equation of the line in fully simplified slope-
intercept form.”
Answer:
y = 3/5x + 5
Step-by-step explanation:
Slope-intercept form is y = mx + b where m is the slope (rise / run of the line) and b is y-intercept (y value of where the line intersects with the y-axis.
The line is rising up 3 and run to the right 5 and so it's slope is 3/5. The line intersects with the y-axis at a y value of 5 and so it's y-intercept is 5.
Therefore, your answer in slope-intercept form is y = 3/5x + 5.

If m∠4 = 131°, find each given angle measure. Justify your answer.
a. m∠8 =
b. m∠5
c. m∠2
d. m∠1
e. m∠6
f. m∠7
Answer/Step-by-step explanation:
Given:
m<4 = 131°
a. m<8 = 180 - m<4 (linear pair)
m<8 = 180 - 131 (substitution)
m<8 = 49°
b. m<5 = m<4 (alternate exterior angle are congruent)
m<5 = 131° (substitution)
c. m<2 = m<5 (vertical angles are congruent)
m<2 = 131° (substitution)
d. m<1 = m<8 (vertical angles are congruent)
m<1 = 49° (substitution)
e. m<6 = m<1 (vertical angles are congruent)
m<6 = 49° (substitution)
f. m<7 = m<4 (vertical angles are congruent)
m<7 = 131° (substitution)

Step-by-step explanation:
Alice earns £450 in wages per month.
She pays £200 rent per month.
Next month.
her wages will increase by 2%
her rent will increase by 5%
She says
"The increase in my wages will pay for the increase in my rent."
Is she correct?
You must show your working.
Answer:
false
Step-by-step explanation:
Since in the question it is mentioned that the wages would be increased by 2% and rent would increase by 5%
So, the increased value of both is
= $450 × 1.02
= $459
And,
= $200 × 1.05
= $210
As the wages are increased to $9 and the rent is increased to $10 since the amount is not equivalent to each other so the given statement is false

If the radius of Brenda's bicycle wheel is 13 inches, approximately how many inches are there in the circumference of the wheel?
Answer:
There are approximately 82 inches
Step-by-step explanation:
Here, we want to calculate the circumference of the wheel
To do this, we are going to use the formula for the circumference of a circle
C = 2 * pi * r
C = 2 * pi * 13
= 26 * pi
C = 81.7 inches which is approximately 82 inches

what is 4.2 less than 7.6
Answer: 3.4
Step-by-step explanation: 6-2 is 4 and 7-4=3 therefore it’s 3.4
The solution is 3.4
The value of the equation 4.2 less than 7.6 is 3.4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is expressed as
A = 4.2 less than 7.6
Substituting the values in the equation , we get
A = 7.6 - 4.2 be equation (1)
On simplifying the equation , we get
The value of A = 7.6 - 4.2
The value of A = 3.4
Therefore , the value of A is 3.4
Hence , The value of the equation 4.2 less than 7.6 is 3.4
