Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
13
8
Answer:
129.1 square units
Step-by-step explanation:
First, let's find the area of the rectangle. We can use the formula below.
[tex]a=lw[/tex]
where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
The length of the rectangle is 13 and the width is 8.
[tex]l=13\\w=8[/tex]
Substitute the values into the formula.
[tex]a=13*8[/tex]
[tex]a=104[/tex]
Next, let's find the area of the semicircle. We can use the formula below.
[tex]a=\frac{1}{2} *\pi r^2[/tex]
First, find the radius. The radius is half of the diameter, and the diameter is 8.
⇒ r= d/2
⇒ r= 8/2
⇒ r= 4
[tex]a=\frac{1}{2} *\pi (4)^2[/tex]
Evaluate the exponent.
⇒ 4² = 4*4 = 16
[tex]a=\frac{1}{2} *\pi *16[/tex]
Multiply pi and 16.
[tex]a=\frac{1}{2} *50.2654825[/tex]
Multiply.
[tex]a=25.1327412[/tex]
Finally, find the area of the figure.
Add the area of the rectangle (104) and the area of the semicircle (25.1327412)
[tex]104+25.1327412[/tex]
[tex]129.132741[/tex]
Round to the nearest tenth. The 3 in the hundredth place tells us to leave the 1 in the tenth place.
[tex]129.1[/tex]
The area of the figure is about 129.1 (square units).

Answer:
Look below
Step-by-step explanation:
To figure whether a line is perpendicular or parallel check the slopes
When a line is parallel the slopes are the same
When a line is perpendicular the slopes are negative reciprocals
40. Neither (They aren't the same nor a negative reciprocal)
41. Neither (When you put y on the left it isn't a reciprocal)
42. Parallel (The slopes are both -3/2)
To do 43-44 make sure that the slopes are the same then plug in the points to to find the y-intercept (make sure you solve for b)
43. y = -4x - 1
44. y = 2x + 1
For 45-46 do the same thing, but make sure you change the slope to a negative reciprocal since its perpendicular
45. y = -3/2x-11
46. y = 1/4x+4

consider this right triangle with given measures what is the unknown length
Answer:
b = 9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 12² = 15²
b² + 144 = 225 ( subtract 144 from both sides )
b² = 81 ( take the square root of both sides )
b = [tex]\sqrt{81}[/tex] = 9

Answer: in exact form: 291.5 + 30.25π cm²
correct to 2 decimal places: 386.53 cm²
Step-by-step explanation:
first you find the area of the rectangle:
= length × width
= 53 × 11
= 583 cm²
Next you find the area of the semicircle:
= π × r² (where r is the radius)
= π × (11/2)²
= 30.25π cm²
Then you find the area of the unshaded triangle:
= half × base length × perpendicular height
= 1/2 × 53 × 11
=291.5 cm²
Finally you subtract the unshaded area (the triangle) from the shaded area (not including the semicircle) then add the semicircle to your result.
= 583 (rectangle) - 291.5 (triangle) + 30.25π (semicircle)
= 291.5 + 30.25π
≈ 386.53 cm² (2 decimal places)

Answer:
4. k = -2 or k = -5
6. m = 5 or m = -21
Step-by-step explanation:
Here is the rule:
To solve an absolute value equation, get the absolute value alone on one side. Then split it into two equations separated by the word or. Each equation has what is inside the absolute value on the left side, and on the right side, one equation has the right side of the absolute value equation, and the other equation has the negative of the right side of the absolute equation.
This is a long explanation which is easier to understand with an example.
Example:
|3x + 2| = 16
Split it into two equations separated by the word "or."
3x + 2 = 16 or 3x + 2 = -16
You see that the left side of the two equations is the inside of the absolute value. The right side of the two equations is positive and negative 16 as explained int he rule.
4.
3 = |2k + 7|
Switch sides.
|2k + 7| = 3
Follow the rule above and split the equation into two equations separated by the word "or."
2k + 7 = 3 or 2k + 7 = -3
2k = -4 or 2k = -10
k = -2 or k = -5
6.
3|m + 8| = 39
We want the absolute value alone on the left side, so divide both sides by 3.
|m + 8| = 13
Now apply the rule above to split the equation into two equations.
m + 8 = 13 or m + 8 = -13
m = 5 or m = -21

If total sales in the ice cream category were $4.4 billion and Breyer’s sales were $650,417,792, what would be its market share? Round your answer to the tenth decimal place.
Answer:
14.8%
Step-by-step explanation:
The formula for market share = Total sales of the company at a particular period/ Total sales of the market × 100%
Total sales of the company = Breyer's sales = $650,417,792
Total sales of the market = Total sales in the ice cream category market = $4.4 billion
= $650,417,792/ $4,400,000,000, × 100
= 14.782222545%
Therefore, approximately to the nearest tenth, Breyer's market share is 14.8 %
Which of the following describes a situation where the total distance a person traveled is 0 feet from the starting point? A. Wyatt drove 25 miles west and then 10 miles in the opposite direction B. Wyatt drove 25 miles east and then 25 in the opposite direction C. Wyatt drove 25 miles north then 20 miles in the opposite direction D. Wyatt drove 25 miles south and then 19 miles in the opposite direction
Answer:
B. Wyatt drove 25 miles East and then 25 miles in the opposite direction
Step-by-step explanation:
This is because he drove East but then drove the same distance back, so he is basically cancelling out the distance he already traveled. Therefore, the traveled 0 feet from the starting point.
Answer:
B. Wyatt drove 25 miles east and then 25 in the opposite direction
Step-by-step explanation:
if you drive x amount of miles in one direction and then the oposite you return where you statred.

There are 12 inches in 1 foot and 5,280 feet in 1 mile. Elena ran 2 1/2 miles. How many feet is that? Elena ran __________ feet.
Answer:
13,200 feet
Step-by-step explanation:
5,280 x 2 1/2 = 13,200
Answer:
13200
Step-by-step explanation:
5280 / 2 = 2640
5280+5280+2640=13200
2640 is half of 5280, which means it is the 1/2 part.

Find the x-intercepts.
y =
2x2 + 5x + 2
x2 - 4x + 3
(-0.5, [?]), ([ ], [ ])
Answer:
Step-by-step explanation:
2x² + 5x + 2=0 (roots or zeros)
(2x+1)(x+2)=0
2x+1=0 ⇒ x=-1/2 or -0.5
x+2=0 ⇒ x=-2
(-0.5,-1/2)x² - 4x + 3=0
(x-3)(x-1)=0
x-3=0 ⇒ x=3
x-1=0 ⇒ x=1
(3,1)Two of the most expensive cars in the world are car A and car B. The prices of these two cars differ by more than $10,000. The price of car A is $130,645. a. Assuming that you do not know which model is more expensive, write an absolute value inequality that describes this situation. Use x for the price of car B. b. What are the possibilities for the price of car B?
Part a.
x = price of car B
x-130645 = difference in price from car A to car B
If x is the larger price, then x-130645 will be positive. If x is the smaller price, then x-130645 is negative.
In short,
x-130645 > 0 when x > 130645x-130645 < 0 when x < 130645Using absolute value will give us
|x-130645| = positive difference in price
The result of an absolute value is never negative
We write the |x-130645| > 10000 to indicate that the difference in price is more than 10000 dollars.
-----------
Answer: | x-130645 | > 10000
================================================
Part b.
We'll use the idea that if |x| > k, then x < -k or x > k
to get the following
|x-130645| > 10000
x-130645 < -10000 or x-130645 > 10000
x < -10000+130645 or x > 10000+130645
x < 120645 or x > 140645
-----------
Answer:
Car B has a price less than $120,645
OR
Car B has a price greater than $140,645
So basically anything that is not between 120645 and 140645. The price has to be positive of course.
−(32 − 12) + 4 ÷ 2 please help
Answer:
-18
Step-by-step explanation:
Answer:
-18
Step-by-step explanation:
You have to follow the order of operations so first off, we'd do -(32-12) which is negative twenty.
Now we're left with;
-20 + 4/2
Here we're going to do division before we add so,
4/2 is 2
All that's left would be,
-20 + 2 which equals -18
Hope that helps, and have a great day!
