Answer: 15
Step-by-step explanation: Use the formula: [tex]a^{2}+b^{2}=c^{2}[/tex]
Remember [tex]c^{2}[/tex] should always be the hypotenuse or the longest side.
[tex]112^{2}+b^{2}=113^{2}[/tex] ---> evaluate the exponents
[tex]12544+b^{2}=12769[/tex] ----> subtract 12544 to the other side
[tex]b^{2}=225[/tex] ---> take the square root of both sides
[tex]b=15[/tex]

Isaiah brought two dozen donuts to a class party. Half of the donuts had vanilla frosting with sprinkles, 2 had strawberry frosting with cream filling, and the rest had chocolate frosting with sprinkles. what fraction of the donuts had sprinkles?
Answer: 22
Step-by-step explanation:
Two dozen equals 24, divide it in half leaves 12 vanilla sprinkle doughnuts
the remaining 12 minus the 2 strawberry cream equals 10 chocolate sprinkles
add the 10 chocolate plus 12 vanilla to get 22
Find the missing side of the triangle leave answer in simplist radical form
Answer: x = 3 √21
Step-by-step explanation:
you gotta use our good, old, trusty friend pythagorean theorem.
a^2 + b^2 = c^2
x^2 + 6^2 = 15^2
x^2 = 15^2 - 6^2
x^2 = 189
x = √189
x = √27 · 7
x = 3 √3 · 7
x = 3 √21

Mr. Jackson had two jobs in 2005. The first job, in which he earned $74,007 was from January to August, and the second job, in which he earned $35,311 was from August to the end of the year. Because he worked two jobs he over paid his Social Security. How much should he be refunded?
9514 1404 393
Answer:
$1,197.71
Step-by-step explanation:
The 6.2% Social Security tax applied to the first $90,000 of earnings in 2005, so Jackson is due to be refunded the tax he paid on more than that amount.
6.2% × (74,007 +35,311 -90,000) = 6.2% × 19,318 = $1,197.71
Jackson should receive a Social Security tax refund of $1,197.71.
_____
Comment on rounding
The tax on 74,007 will be rounded down, as will the tax on 35,311. So, the overpayment value calculated here needs to be rounded down to correspond to the actual to-the-penny amount of overpayment.

Answer:
x= 108
Step-by-step explanation:
use inverse operations to subtract 129 from both sides
x+129=237
-129 -129
x=108

A study is run comparing HDL cholesterol levels between men who exercise regularly and those who do not. The data are shown below.
Generate a 95% confidence interval for the difference in mean HDL levels between men who exercise regularly and those who do not.
Answer:
Hello your question is incomplete attached below is the missing part of the question
Regular Exercise N Mean Std Dev
Yes 35 48.5 12.5
No 120 56.9 11.9
answer : ( -12.968, -3.832 )
Step-by-step explanation:
To generate a 95% confidence interval
first step :
Assume population variance is equal we will calculate the number of degrees of freedom
df = n1 + n2 - 2 = 35 + 120 -2 = 153
second step:
Given : critical value = 0.05 , df = 153
hence Tc = 1.976
assuming the population variance is equal calculate pooled std as ( attached below )
Sp = 12.036
third step :
calculate the standard error
Se = [tex]Sp\sqrt{\frac{1}{n1} +\frac{1}{n2} }[/tex]
n1 = 35
n2 = 120
Sp = 12.036
hence Se = 2.312
final step
Compute the 95% confidence interval = ( -12.968, -3.832 )
attached below is the detailed solution
A charity bingo game costs $2 per round and has a $13 entry fee for an adult. It costs $3 per round and a $10 entry fee for a child. For how many rounds of bingo are the costs the same for an adult and a child?
2
3
4
5
Answer:
B=3
Step-by-step explanation:
Use a graphing calculator and type in these toe equations
y=2x+13
y=3x+10
and the point they intersect will say (3,19) and the answer is 3
For 3 rounds of bingo, the costs will be the same for an adult and a child option second is correct.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A charity bingo game costs $2 per round and has a $13 entry fee for an adult. It costs $3 per round and a $10 entry fee for a child.
Let's suppose, for x rounds of bingo, the costs will be the same for an adult and a child.
For x rounds, cost for adult:
= 2x + 13
For x rounds, cost for child:
= 3x + 10
2x + 13 = 3x + 10
x = 3
Thus, for 3 rounds of bingo, the costs will be the same for an adult and a child option second is correct.

The answer is that Topsoil costs 10$ more than mulch.
When we look at the equation y=20x, we see that for one cubic yard, it costs 20$. when we look at the graph, we see that for one cubic yard it costs 30$ for topsoil, therefore, Topsoil is $10 more than mulch for each cubic yard.

You've sold 101 rooms, 98 rooms, and 102 rooms over the past 3 days. You have 116 rooms available. What is your average occupancy for the past three nights?
Answer:
The average occupancy rate for the past three nights is of 86.49%.
Step-by-step explanation:
We want to find the average occupancy rate, as a percentage.
You've sold 101 rooms, 98 rooms, and 102 rooms over the past 3 days.
So the mean number of rooms sold during the past 3 days is given by:
[tex]A = \frac{101 + 98 + 102}{3} = \frac{301}{3} = 100.33[/tex]
Average rate:
[tex]R = \frac{100.33*100}{116} = 86.49[/tex]
The average occupancy rate for the past three nights is of 86.49%.

I need help I don’t understand this
Answer:
Step-by-step explanation:
lets say "a" for the empty line,
for small triangle; y^2 = 2^2 + x^2
right triangle; we say a for empty line, a^2= 6^2 + x^2
and big triangle covering both triangles, 8^2 = y^2 + a^2
lets add left sides and right sides in each;
x^2 + 4 + x^2 + 36 + y^2 + a^2 = y^2 + a^2 + 64 and we can delete same things for both sides
y^2 and a^2 can be deleted and 4+36 - 64
2(x^2)=24
x^2= 12
and x will be √12
so, y^2 = x^2 + 2^2 which means y^2 = 12+4 y=16

Find all zeros of f(x) = x4 + 5x2 – 36 by completely factoring the polynomial.
f(x) = x4 + 5x2 – 36 = (x2 – 4) (x2 + 9) =
List the four zeros of the function.
Real zeros: +
Complex zeros:
Answer:
Real Zeros x = ±4
Complex zeros : x = ±3 i
Step-by-step explanation:
Explanation
f(x) = x⁴ + 5x² – 36
f(x) = x⁴ + 5x² – 36
= (x²)² + 9 x² - 4 x² - 36
= x² (x² + 9) - 4( x² +9)
= (x² -4 ) (x² +9)
f(x) = x⁴ + 5x² – 36 = (x² -4 ) (x² +9)
(x² -4 ) (x² +9) = 0
⇒ x² -4 = 0 and x² +9 =0
⇒ x² -2² = 0 and x² = -9
⇒ x = ±4 and x = ±3 i
Real Zeros x = ±4
Complex zeros : x = ±3 i
