r = 4 in., θ = 11 rad; find s
Answer:
The arc length s = 44 inches
Step-by-step explanation:
We are given:
r = 4 in
Ф = 11 radians
We need to find s
The formula used is: [tex]s=r\theta[/tex]
where s represents arc length, r is radius and Ф is angle in radians
Putting values and finding s
[tex]s=r\theta[/tex]
Put r = 4 and Ф = 11
[tex]s=4\times 11\\s=44[/tex]
So, the arc length s = 44 inches

If the principal is $10, 624 and the rate of interest is 6.25%, what is the amount of interest after four years?
Answer:
$2656
Step-by-step explanation:
6.25% of $10,624 is $664, so that is the amount of interest every year.
$664 times 4 is $2656, so after 4 years $2656 will have been paid.

Step-by-step explanation:
This is a right triangle, which we know because of the square in the corner of the triangle. We can use the right triangle trigonometric ratios.
[tex]sin( \theta) =opposite/hypotenuse[/tex] and [tex]cos (\theta) = adjacent /hypotenuse[/tex] and [tex]tan (\theta)=opposite/adjacent[/tex]
First, identify each side of the triangle as adjacent, opposite, or hypotenuse, relative to the 68 degree angle.
The x is next to, or adjacent, to the angle. The 24 is opposite. We are not given the hypotenuse.
[tex]adjacent= x \\opposite= 24 \\hypotenuse= unknown[/tex]
Since we have the adjacent and opposite, we must use tangent.
[tex]tan (\theta)=\frac{opposite}{adjacent}[/tex]
Substitute the values in. The theta (θ) is the angle.
[tex]tan (68)=\frac{24} {x}[/tex]
Solve for x. One way is by cross multiplying.
[tex]\frac{tan(68)}{1}=\frac{24}{x}[/tex]
Multiply the 1st numerator by the 2nd denominator. Then, multiply the 1st denominator by the 2nd numerator.
[tex]tan (68)*x=1*24[/tex]
[tex]tan(68)*x=24[/tex]
Evaluate tan(68) using a calculator.
[tex]2.47508685*x=24[/tex]
Divide both sides of the equation by 2.47508685. This will isolate the variable x. ( We divide because multiplication is occurring between 2.47508685 and x, and division is the inverse of multiplication).
[tex]\frac{2.47508685*x}{2.47508685}=\frac{24}{2.47508685}[/tex]
[tex]x=\frac{24}{2.47508685}[/tex]
[tex]x=9.69662943[/tex]
Round to the nearest tenth. The 9 in the hundredth place tells us to round up. The 6 becomes a 7.
[tex]x \approx 9.7[/tex]
In this right triangle, x is equal to about 9.7

The cost of renting a car is $25 per day plus a one-time fee of $75.50 for insurance. How many days can the car be
rented if the total cost is to be no more than $525?
Answer:
the second choice 25x+75.50<525
75.50 + 25x < 525
The car can be rented for 17 days.
On the line you will have a lone pointing to the left with an open circle on 17.
75.50 + 25x < 525
25x < 525 - 75.50
25x < 449.50
x < 449.50/25
x < 17.98

5+3w+3-w combine like terms to simplify
Answer:
8 + 2w
Step-by-step explanation:
⇒ Change all signs to addition (subtraction is the same as adding a negative):
5 + 3w + 3 + -w
⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:
5 + 3 + 3w + -w
⇒ Simplify:
8 + 2w
Answer: 8 + 2w

John and his best friend found some money. They split the money evenly, each getting $14. How much money did they find?
Answer:
$28
Step-by-step explanation:
John and his best friend each got $14, so in total there are $14+$14=$28.
Answer:
$28
Step-by-step explanation:
If they split the money evenly then both of them got half.
So, multiply 14 by 2 to find the answer:
(14)(2) = 28
John and his best friend found a total of $28.

Help
Answer:
The area is 12x^2
Step-by-step explanation:
John buys two types of tree saplings. One starts out at 40 cm and will grow 10 cm every three months. The other sapling starts at 20 cm and will grow 10 cm every two months. After how many months will they be the same height, and how tall will they be? solve for y and x
Answer:
They will at the same height of 80cm at 12 months.
Step-by-step explanation:
Sapling A:
y = 10/3x + 40
Sapling B:
y = 5x + 20
Set the equations to equal each other.
10/3x + 40 = 5x + 20
10/3x - 5x = 20 - 40
10x - 15x = 60 - 120
-5x = -60
x = 12
Sub x = 12 into one of the two equations (It doesn't matter which one you choose)
y = 5(12) + 20
y = 80

The length of QT should be considered when the Parallelogram QRST where QR = 6X - 5 is to be [tex]x=-13/3[/tex].
Calculation of the length of QT:SInce
Parallelogram QRST where QR = 6X - 5 and RS = 4x + 13
So here we can write like
-3x = 13
x = [tex]-13 /3[/tex]

Sara missed 7 of 184 school days this year. Approximately what percent of school days was Sara present?
A. 4%
B. 96%
C. 177%
D. 7%
Answer:
B. 96%
Step-by-step explanation:
Sara only missed 7 days of 184 days this year meaning 184 - 7 = 177 and
177 is how many days she attended school, so to figure out percentage take the number of days she attended school and divide by the total amount of days in this year which is 184: 177/184 = 0.96195652173
then multiply by 100 to get percentage so approximately 96%.
