Answer:
37.7 (approx.)
Step-by-step explanation:
The radius of the biggest circle is 3+2=5. And so the area is [tex]\pi (5)^2 = 78.54[/tex]. In the same way, the area of the two small circles are [tex]\pi (3)^2 = 28.27[/tex] and [tex]\pi (2)^2 = 12.57[/tex]
So, the area of shaded region = Area of the biggest circle - (area of small two circles)
[tex]= 78.54 - (28.27 + 12.57)\\37.7 (approx.)[/tex]
Help please and thankyou :)
Answer:
1/2
Step-by-step explanation:
As you probably know 10 is double the size/amount of 5, but instead of just putting 2 you would put 1/2. That is because it is a scale factor of a scale drawing, which is not the same size and is supposed to be smaller because you can't draw a house on a paper that would fit it literally ;)

How can you determine if the given lines are perpendicular?
Answer:
Step-by-step explanation:
Two lines are perpendicular if and only if the product of their slopes is . In other words, the slope of a line that is perpendicular to a given line is the negative reciprocal of that slope. Thus, for a line with a given slope of 3, the line perpendicular to that slope must be the negative reciprocal of 3, or .

Determine b value
An exponential equation is:
[tex]y = ab^x[/tex]
When [tex]x = 0; y =2[/tex]
So:
[tex]y = ab^x[/tex]
[tex]2 = a * b^0[/tex]
[tex]2 = a[/tex]
[tex]a = 2[/tex]
When [tex]x = 2; y = 18[/tex]
So:
[tex]18 = a * b^2[/tex]
Substitute 2 for a
[tex]18 = 2 * b^2[/tex]
Divide by 2
[tex]9 = b^2[/tex]
Take positive square roots of both sides
[tex]3 = b[/tex]
[tex]b = 3[/tex]

For each of the figures, write an Absolute Value equation to satisfy the given solution set.
Answer:
|x-5|=2
Step-by-step explanation:
1- Find the mid value between the given numbers 3 and 7
(3+7)/2= 10/2 = 5
2- Find the difference btween the mid value (5) and any of the two given numbers (3 or 7). Use the absolute value for the difference.
|5-3|= 2 or |7-5|=2
3- Arrange the absolute equation like this:
|x-mid value from step 1|= absolute difference from step 2
|x-5|=2
4- Double check the answer with the given values 3 and 7 using our equation |x-5|=2
|3-5|=2 correct
|7-5|=2 correct

What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
Where (a, b) an (c, d) are the two points.
We have,
Hexagon PQRSTU.
Vertices.
P = (–1, 0)
Q = (–1, 3)
R = (1, 4)
S = (2, 5)
T = (4, 4)
U = (4, 0)
Now,
We can make 6 lines.
PQ, QR, RS, ST, TU, and PU
We find the distance between each line.
PQ = [tex]\sqrt{(-1 + 1)^2 + (3 - 0)^2}[/tex] = 3
QR = [tex]\sqrt{(1 + 1)^2 + (4 - 3)^2}[/tex] = √5
RS = [tex]\sqrt{(2 - 1)^2 + (5 - 4)^2}[/tex] = √2
ST = [tex]\sqrt{(4 - 2)^2 + (4 - 5)^2}[/tex] = √5
TU = [tex]\sqrt{(4 - 4)^2 + (0 - 4)^2}[/tex] = 4
PU = [tex]\sqrt{(4 + 1)^2 + (0 - 0)^2}[/tex] = 5
Now,
The perimeter of the hexagon.
= 3 + √5 + √2 + √5 + 4 + 5
= 12 + 2√5 + √2
Thus,
The perimeter of the hexagon is 12 + 2√5 + √2

Given sinx=1/3, cosy=3/4, and both x and y are in quadrant iv, find cos(x-y) and sin(x+y)
Answer: [tex]\dfrac{6\sqrt{2}+\sqrt{7}}{12},\ \dfrac{-3-2\sqrt{14}}{12}[/tex]
Step-by-step explanation:
Given
x and y is in the fourth quadrant
[tex]\sin x=-\dfrac{1}{3}\\\\\cos y=\dfrac{3}{4}[/tex]
we know,
[tex]\cos (x-y)=\cos x\cos y+\sin x\sin y\\\sin (x+y)=\sin x\cos y+\cos x\sin y[/tex]

Citlali was traveling at 60 miles per hour. she has already traveled 120 miles. To get to california which is 360 miles from home, and traveling at the same average speed, how many more hours will it take before he arrives in california?
Answer:
4 more hours
Step-by-step explanation:
First, you know that Citlali is traveling 60 miles per hour so he travels 60 miles every hour. He has already traveled 120 miles so you subtract 120 from 360 because that is the amount of miles Citlali now has to travel. Then, you know that she travels 60 miles per hour so the equation will be 60x=240. Then, you divide 60 in both sides and get x=4. Therefore, it will take four more hours until he arrives at California.

$37.30 for 2 pairs of jeans
Answer:
18.65
Step-by-step explanation:
Logan is taking a loan out to buy a $4000 right for his wife. He has two finance options listed below. Which should he choose? Option a- a five year loan with a %7 interest rate compounded quarterly l. Option b- an eight year loan with a 5.5% interest rate compounded annually
Answer:
The most convenient option for Logan is A, since he will pay a lower amount than if he chose option B.
Step-by-step explanation:
Given that Logan is taking a loan out to buy a $ 4000 right for his wife, and he has two finance options, Option A, which gives a five year loan with a% 7 interest rate compounded quarterly, and Option B, which gives an eight year loan with a 5.5% interest rate compounded annually, to determine which option should be chosen, the following calculation must be performed:
Option A:
X = 4,000 (1 + 0.07 / 3) ^ 5x3
X = 5,653.49
Option B:
X = 4,000 (1 + 5.5 / 1) ^ 8x1
X = 6,138.75
Thus, the most convenient option for Logan is A, since he will pay a lower amount than if he chose option B.
When Jaya goes bowling, her scores are normally distributed with a mean of 105 and a standard deviation of 10. Using the empirical rule, determine the interval that would represent the middle 95% of the scores of all the games that Jaya bowls.
Answer: (75, 135)
Step-by-step explanation:
Because the empirical rule is 3 standard deviations of the mean you would add and subtract to get your desired interval.
In this case our mean is 105 and our deviation is 10.
What you would do is add 10 to 105, 3 times to find your greatest number and the you would subtract 10 from 105, 3 times to get your lowest number.
105 + 10 + 10 + 10 = 135
105 - 10 - 10 - 10 = 75
