Answer:
562.29
Step-by-step explanation:
you would just multiply 525.50 by 7 which is 3678.5 and divide that by 100 which is 36.785 and add that to 525.50 which is 562.285 which can be rounded to 562.29

If x + 4 is one factor of x3 + 64, what is the other factor?
Answer:
[tex]\Huge \boxed{(x^2 - 4x + 16)}[/tex]
Step-by-step explanation:
x³ + 64
64 is a perfect cube. Rewrite 64 as 4³.
x³ + 4³
Apply sum of cubes formula:
a³ + b³ = (a + b)(a² - ab + b²)a = x
b = 4
(x + 4)(x² - (x)(4) + 4²)
(x + 4)(x² - 4x + 16)
(x² - 4x + 16) is the other factor.

Solve for X.........
Answer:
Hey there!
There is this equation, which states that the angle created by an inscribed angle is half the measure of the arc.
Thus, we can write: 60=5x-5
65=5x
x=13
Let me know if this helps :)
Answer:
x= 13
Step-by-step explanation:
Inscribed Angle =1/2 Intercepted Arc
30= 1/2 (5x-5)
Multiply each side by 2
60 = 5x-5
Add 5 to each side
65 = 5x
Divide by 5
13 =x

sam is baking cakes at her parents bakery. she gets paid $20 a week in addition to $4 for every cake she bakes. she made $60 this week. write an equation to show how many cakes sam baked this week
Answer:
She made 10 additional cakes
Step-by-step explanation:
x = additional cake
20 = base salary
y = 4x + 20
60 = 4(x) + 20
40 = 4(x)
x = 10
Less than 75% of workers got their job through internet resume sites. A researcher thinks it has increased.
Express the null and alternative hypotheses in symbolic form for this claim. For example, if you have 35%, enter it as 0.35.
H0: p H1: p
Use the following codes to enter the following symbols: ? enter >= ? enter <= ? enter ! =
Answer:
H0 : p = 0.75 against H1: p > 0.75 One tailed test.
Step-by-step explanation:
We state our null and alternative hypotheses as
H0 : p = 0.75 against H1: p > 0.75 One tailed test.
In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.
The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.
As H0 is supposed to be less than we choose H1 to be greater than equality.

State the trigonometric substitution you would use to find the indefinite integral. Do not integrate. (25 + x2)−6 dx x(θ) =
Answer:
x(θ) = 5 tan θ
Step-by-step explanation:
Given that:
[tex]\int (25+x^2)^{-6} \ dx[/tex]
we are to state the trigonometric substitution to be used to find the indefinite integral.
Suppose u is the variable and a is the constant
u = x
a = 5
So; (a² + x²)ⁿ
which is a trigonometric substitution for x = a tanθ
Then,
x(θ) = 5 tan θ
In this exercise we have to use the knowledge of trigonometric substitution to calculate the indefinite integral, so we have that this is:
[tex]x(\theta) = 5 tan \theta[/tex]
Knowing that the indefinite integral corresponds to:
[tex]\int\limits {(25+x^2)^{-6}} \, dx[/tex]
we are to state the trigonometric substitution to be used to find the indefinite integral. Suppose u is the variable and a is the constant:
[tex]u = x\\a = 5\\(a^2 + x^2)^n[/tex]
Which is a trigonometric substitution for:
[tex]x = a tan\theta\\x(\theta) = 5 tan \theta[/tex]

The value 191.5638 rounded to the nearest hundredth is
191.564
191.5600
191.56
200
Answer:
191.56
Step-by-step explanation:
Given
191.5638
Required
Approximate
Approximating to the nearest hundredth implies that, only to digits after the decimal point is needed
This is:
191._ _
The third digit after the decimal point will approximated using the approximation rule;
Since, the third digit after the decimal point (3) is not up to 5, it'll be approximated to 0 and added to the second digit (6)
So, we have:
191.5 _
The next digit is calculated as 6 + 0 = 6
Hence, the full approximated number is 191.56
if the length of rectangle changes from 148.5cm to 144 cm. Find the percentage
change in the length.
Answer:
Original height = 144 cm
Increase height = 148.5 cm
Change in height = 148.5 - 144 = 4.5 cm
Percentage change = change/original ×100
= (4.5 / 148.5) × 100
= 3.03%
The height increased by 3.03%.
Step-by-step explanation:
Answer:
3%
Step-by-step explanation:
148.5 - 144 = 4.5
[tex]\frac{Difference}{Initial Amount}[/tex] × 100
[tex]\frac{4.5}{148.5}[/tex] × 100 = 3.03 ≈ 3%

is -0.23 rational number whole number or integers
Answer:
rational number
Step-by-step explanation:
A whole number does not have a decimal part so it cannot be a whole number
Integers are whole numbers that are positive and negative plus zero
-.23 can be written as the ratio of integers
-23/ 100 so it is a rational number
Answer:
Rational
Step-by-step explanation:
A whole number does not have a decimal part so it cannot be a whole number
Integers are whole numbers that are positive and negative plus zero
-.23 can be written as the ratio of integers
-23/ 100 so it is a rational number
flying against the wind, a jet travels 4600 miles in 5 hours. flying with the wind, the same jet travels 4200 miles in 3 hours. what is the rate of the jet in still air and what is the rate of the wind?
Answer:
The rate of the jet in still wind is 1160 MPH and the rate of the wind is 240 MPH.
Step-by-step explanation:
Distance equals rate times time (d = rt)
Against the wind, the rate is:
4600 = r * 5
r = 4600/5 = 920 MPH
With the wind, the rate is:
4200 = r * 3
r = 4200/3 = 1400 MPH
Let W be the rate of the wind in MPH. We know that:
(rate of the jet against the wind) + (rate of the wind) = (rate of the jet with the wind ) - (rate of the wind), so:
920 + W = 1400 - W
2W = 480
W = 240 MPH
And the speed of the jet in still air would be:
1400 - 240 = 1160 MPH
Kevin mowed 12 lawns and earned a total of $60.
Which rate represents the amount of money earned per lawn?
Answer:
$5
Step-by-step explanation:
$60 earned for moving 12 lawns
Amount of money per lawn is:
$60/12= $5Answer is amount per lawn is $5
Answer:
$5
or
$5 / 1 lawn
Step-by-step explanation:
The process is quite simple - especially since you already have half of the answer. The question says money per lawn. The creator of the problem gave away a lot of the answer. They already tell us the rate. Now all ou have to do is plug the numbers in:
Money per lawn
Money / lawns (The slash is used to represent per)
What is the money? $60. So plug that in:
$60 / lawns
How many lawns? 12. Plug that in:
$60 / 12 lawns
Now, all you have to do is either simplify the fraction or divide the denominator by the numerator - whichever one you prefer. In that case, the rate can be any of the following:
$5
$5 / 1 lawn

Strawberries cost $21.25 for 4 pounds. Find the unit rate. Round to the nearest cent if necessary.
Answer:
$5.31/lb
Step-by-step explanation:
Since 4 pounds cost $21.25, 1 pound of strawberries will cost 21.25 / 4 ≈ 5.31, therefore, the unit rate is $5.31/lb.
Answer:
$5.31 per pound.
Step-by-step explanation:
$21.25 for so
%21.25/4= $5.31
The answer is $5.31 per pound.

Use the figure to the right to find the value of PT. T is the midpoint of PQ PT=7x+9 and TQ=9x-5
Answer:
58
Step-by-step explanation:
Since, T is the mid point of PQ,
[tex] \therefore PT = TQ \\
7x + 9 = 9x - 5\\
9 + 5 = 9x - 7x\\
14 = 2x \\
\frac{14}{2} = x\\
7 = x \\
x = 7\\
PT = 7x + 9 = 7\times 7 + 9= 49 + 9 \\
PT= 58

Neal opened a savings account 11 years ago with a deposit of $2,335.69. The account has an interest rate of 4.3% compounded daily. How much interest has Neal earned? (3 points)
$1,412.52
$2,436.12
$1,375.75
$3,748.21
Answer: $1,412.52
Step-by-step explanation:
Formula to calculate the accumulated amount if P principal invested for t years at a rate of interest r that compounded daily is given by:-
[tex]A=P(1+\dfrac{r}{365})^{365t}[/tex]
Given: P= $2,335.69
r= 4.3%= 0.043
t= 11 years
Then,
[tex]A=2335.69(1+\dfrac{0.043}{365})^{365\times11}\\\\=2335.69(1+0.000117808219178)^{4015}\\\\=2335.69(1.000117808219178)^{4015}\\\\= 2335.69(1.6047566747)\\\\=3748.09044309\approx3748.21\\\\\Rightarrow\ A=\$3748.21[/tex]
Interest earned = A-P
= $3748.21- 2335.69.
= $1412.52
Hence, Neal earned $1,412.52 as interest.
