Find the area of this composite figure.
Answer: ≈ 551.71 ft²
All work is shown in the picture.
Answer:
551,7
see in the picture, this composite figure is made up of a rectangle and 2 halves of a circle
=> the area of this composite figure = the area of a rectangle + the area of a circle
+) the area of the rectangle = 15.25 = 375
+) the area of the circle = (15/2)².pi = 56,25pi
=> the area of this figure = 375 + 56,25pi = 551,7
Two groups of hikers leave the same camp heading in opposite directions. The first group travels 4 miles north and 3 miles east. The second group travels 2 miles south and 5 miles west.
a. Draw the situation in the coordinate plane using a right triangle. Use the origin as the camp location, and let each unit represent 1 mile. For example, the point (2, 1) would represent 2 miles east and 1 mile north of the camp.
b. Determine the distance between the two groups after the hikes.
Question 2
The distance between the two groups is __ miles.

1/3(c) when c = 64. What’s the answer using PEMDAS
Answer:
21.3 repeated
Step-by-step explanation:
Let's look at our equation
1/3c
We also have the number that c stands for, which is 64, so what we must do is replace c with 64.
1/3(64)
Now we have the equation 1 over 3 multiplied by 64, so multiply as is.
64 * 1 = 64
Therefore,
64/3
Now divide :

Belvedere goes to the store and buys a soccer ball for $50. The store
is running a discount of 10%. What is the price of the soccer ball after
the discount?
Answer:
$45 after the discount
Step-by-step explanation:
Set up a proportion.
[tex]\frac{x}{50} = \frac{10}{100}[/tex] $50 is the total amount and make the 10% a decimal
x(100) = 50(10)
100 = 500
100 ÷ 500
x = 5 <-- We have to subtract this amount from the total
$50 - $5 = $45 <-- total after the discount
Hope this helps!!
Which values from the set {0, 1/2 , 2.5, 4} make the inequality 8g < 4 true?
Answer:
only 0
Step-by-step explanation:
8g < 4 simplifies to g < 4/8, i.e., g < 1/2
only 0 is smaller than 1/2

Answer:
g(r - 9) = r² - 18r + 89
Step-by-step explanation:
To evaluate g(r - 9), substitute p = r - 9 into g(p) , that is
g(r - 9) = (r - 9)² + 8 ← expand factor using aFOIL
= r² - 18r + 81 + 8
= r² - 18r +89
given: x+y=10 if x=-21, what is y?
Answer: y = 31
Step-by-step explanation: all you need to do is plug in the x
since x = -21 we can put: -21 + y = 10
now we add 21 to both sides giving us: y = 31
Answer:
(-21,22)
Step-by-step explanation:
x+y=10
x=-21
subtitue the x value
-21+y=2
solve for y
y=22
Then write your answer by ordered pair
(-21,22)

A family of 2 adults and 3 children went on holiday to Miami.
The family visited a theme park.
They paid a total of 322 dollars to go in.
The exchange rate was £1 = 1.84 dollars.
Change 322 dollars to pounds (£).
Answer:
£175
Step-by-step explanation:
Given the exchange rate was £1 = 1.84 dollars.
We are to change 322 dollars to pounds (£).
£1 = 1.84 dollars.
x = 322 dollars
Cross multiply
1.84 * x = 322
1.84x = 322
x = 322/1.84
x = 175
Hence 322 dollars in pounds will be £175

A certain statistic bˆ is being used to estimate a population parameter B . The expected value of bˆ is equal to B . What property does bˆ exhibit? The sampling distribution of bˆ is normal. The sampling distribution of b hat is normal. A The sampling distribution of bˆ is binomial. The sampling distribution of b hat is binomial. B The sampling distribution of bˆ is uniform. The sampling distribution of b hat is uniform. C bˆ is unbiased. B hat is unbiased. D bˆ is biased.
Answer:
C bˆ is unbiased.
Step-by-step explanation:
In statistics, the sampling distribution showcases the distribution of obtained values by the statistics in all possible sample sizes of the same population. A statistic that estimates a population parameter is termed to be an unbiased estimator if the mean of such distribution appears to be equal to the true value of the estimated parameter.
Thus, from the aforementioned, the property exhibited by b- is unbiased.
d is biased
Step-by-step explanation:
The expected value of d is not D
The property where the expected value of d is D is called unbaisedness, hence d is biased

Solve for X. 12y-4x=10
Answer:
x=-5/2+3y
Step-by-step explanation:
If this answer helped you then please consider making this brainliest and thank this response :)
Answer:
x = -2.5 + 3y
Step-by-step explanation:
Simplifying
12y + -4x = 10
Reorder the terms:
-4x + 12y = 10
Solving
-4x + 12y = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12y' to each side of the equation.
-4x + 12y + -12y = 10 + -12y
Combine like terms: 12y + -12y = 0
-4x + 0 = 10 + -12y
-4x = 10 + -12y
Divide each side by '-4'.
x = -2.5 + 3y
Simplifying
x = -2.5 + 3y
