Answer:
b = 9m is the answer.
Step-by-step explanation:
a = 12m
b = ?
c = 15m
According to the Pytagorean theorem,
a² + b² = c²
12² + b² = 15²
144 + b² = 225
b² = 225 - 144
b² = 81
b = 9
∴ The slide is 9m away from the monkey bars.

Find the area of the circle. Round your answer to the nearest hundredth. 3 in
Answers
Answer:
28.27 or 28 rounded up.
Answer:
7.07 in²
Step-by-step explanation:
Diameter = 3 in ( shown in figure )
Radius = 1/2( diameter) = 1/2 (3) = 1.5 in
Area of a circle = πr²
Area = (3.14)(1.5)²
Area = (3.14)(2.25)
Area = 7.065 in
Area = 7.07 in² ( round off)

Step-by-step explanation:
Write the equation of line AB in slope-intercept form, given the points A(0,5) and B(-5,-10) . In your final answer, include all of your calculations.
Answers
Answer:
y = 3x + 5
Step-by-step explanation:
1) First, find the slope between the pair of points. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of points A and B into the formula and simplify:
[tex]m = \frac{(-10)-(5)}{(-5)-(0)} \\m = \frac{-10-5}{-5-0} \\m = \frac{-15}{-5} \\m = 3[/tex]
So, the slope is 3.
2) Now, identify the y-intercept of the line, or the point at which the line intersects the y-axis. All points on the y-axis have an x-value of 0. We're told that (0,5) is a point the line intersects, and since it has an x-value of 0, that must be the y-intercept.
3) Using slope-intercept format, represented by the equation [tex]y = mx + b[/tex], write the equation of the line. Remember that the number in place of [tex]m[/tex], or the coefficient of the x-term, is the slope. So, substitute 3 for [tex]m[/tex]. Also, remember that [tex]b[/tex] represents the y-intercept of a line, so substitute 5 in its place, too. This gives the following answer:
[tex]y = 3x + 5[/tex]
The retail price of a television set is $2500. If the buyer pays cash, the price is 10% below the retail price. If the set is bought on hire purchase, the buyer pays a downpayment of $500 and 18 monthly installments of $150.
A) Determine the difference between the hire purchase price and the cash price.
B) Calculate the difference as a percentage of the retail price.
Answers
Answer:
cash price:
10% = 250
2500 - 250 = $2,250
hire purchase:
2500 + 500 + 150(18) = $5,700
a) 5,700 - 2,250 = $3,450

Answers
Answer:
C) 3x and 7x
Step-by-step explanation:
Both terms in C have the same variable in which you can combine the terms to make 1. The other ones don't.
Answer:
c. 3x and 7x
Step-by-step explanation:
We have three pairs of two terms and are asked to determine which option has "like terms."
Like terms are two numbers with variables that are the same.
With this information, we can determine which is and which isn't like terms.
a. 2x^2 and 4y^2 are incorrect because the variables within the number do not match, 2x^2 and 4y^2.
b. xy and yz are incorrect because the variables also do not match, xy and yz.
c. is correct because the variables within the two numbers are the same. 3x and 7x.

An account is open with initial deposit of $5500 and earn 2.5% interest compounded annually. What will the account be worth in 10 years
Answers
Answer:
FV= $7,040.46
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,500
Number of periods (n)= 10 years
Interest rate (i)= 2.5%
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
FV= 5,500*(1.025^10)
FV= $7,040.46
Emergency rooms have reason to suspect that visits increase on the weekends. A recent report indicates that Monday through Thursday represent 10% per day of the weekly total visits while Friday accounts for 15%, Saturday 25% and Sunday 20%. If your ER has the following pattern, Monday, 120, Tuesday, 130, Wednesday 110, Thursday 95, Friday 160, Saturday 280 and Sunday 105.
Does your facility have the same pattern as the recent report at the 10% level?
1. Yes
2. No
Answers
Answer:
i think i am pretty sure its a yes
No, the facility dose not have the exact pattern as the recent report at the 10% level.

Given that the observed frequency and expected proportion exists given
For Monday
expected frequency = proportion [tex]*[/tex] frequency = 0.1 [tex]*[/tex] 1000 = 100
(O-E)²/E. = ( 120 - 100 )² / 100 = 4.0.

For Tuesday
E = 0.1 [tex]*[/tex] 1000 = 100
(O-E)²/E = ( 130 - 100 )² / 100 = 9.0
For Wednesday through Sunday
Then perform Chi-squared test

Answer:

Step-by-step explanation:
a triangle's angles should all add up together to 180 degrees. Since a right angle is 90 degrees then you have your 60 degree angle that only leaves 30 degrees left.
Answer: A and C
Step-by-step explanation:
A is right because it’s right triangle since it has a right angle. C is also right, x=30 because we have 60 degrees and 90 degrees. 60 plus 90 is 150 and a triangle is equal to 180 degrees 180-150 is 30
