Anyone can help me with math for solving for a side in the right triangles for khan academy
Answer:
7.45
Step-by-step explanation:
We are given a right triangle with one side length known and an angle know so we can use some trigonometry.
You need to find the hypotenuse so you are going to use either sine or cosine.
Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,
cos(20) = 7/h
=>h = 7/cos(20)
=> 7.44924
=> 7.45

Divide using synthetic division (x^2 +9)÷(x-3) =
Answer: x+3+ 18/x-3
Step-by-step explanation:
The complete division problem can be written as:
(x² + 9) / (x-3) = x + 3 + 18/(x-3)
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
To divide using synthetic division, we follow these steps:
Write the dividend (x² +9) and the divisor (x-3) in the form of a long division problem, with the divisor (x-3) written on the outside and the dividend (x² +9) written inside the division brackets.
Write the coefficient of the first term of the dividend (in this case, 1) in the first row of the synthetic division. This will be the first term of the quotient.
Multiply the divisor (x-3) by the coefficient in the first row (1), and write the result (x-3) in the second row.
Add the second term of the dividend (9) to the result in the second row. The result is the coefficient of the second term of the quotient.
Repeat this process until you have found the coefficients of all the terms in the quotient.
Using this process, we can divide (x² +9) by (x-3) as follows:
The quotient is x + 3. The remainder is 18, so the complete division problem can be written as:
(x² + 9) / (x-3) = x + 3 + 18/(x-3)

Math Exit Slip: Value-Mart is having a back -to - school sale on pencils. A pack of of 20 sells for $7.97, whereas a 12-pack costs $4.77. Which is the better buy?
Answer: The pack of 20.
Step-by-step explanation:
It is because a pack of 20 sells for 2.50 for each pencil, and the pack of 12 sells for 2.51 per pencil, so that means the pack of 20 is cheaper.
Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
Answer:
£3,692
Step-by-step explanation:
First four years
A = p(1 + r/n)^nt
P = £2350
r = 4.2% = 0.042
n = 1
t = 4
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Next 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692

feet per minute.
Bob's linear speed is higher than Jack's because the radius of the circle
around which Bob rotates is larger.
Responses:
Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minuteWhat is the relationship between linear speed and angular speed?Given:
The rotational speed of the merry go round = 6 revolution per minute
Jack's distance from the center = 10 feet
Bob's distance from the center = 14 feet
The angular speed, ω, of the merry-go-round is found as follows;
[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × rWhich gives;
Jack's linear speed = 12·π rad/min × 10 feet ≈ 377 feet per minuteBob's linear speed = 12·π rad/min × 14 feet ≈ 527.8 feet per minuteLearn more about angular speed and linear speed here:

5. James makes $15.50 per hour and works 40 hours a week. He pays 26% of his gross earnings in federal and state
taxes. He also saves 7.5% of his monthly gross income to put into savings. He is considering renting an apartment tha
will cost $1,400 per month. Based on his expenses, can he make the monthly payments?
9514 1404 393
Answer:
no
Step-by-step explanation:
On average, there are about 173 1/3 hours per month, so James's take-home pay will be about ...
($15.50/h)(173 1/3 h/mo)(1 -26%) = $1988.13
His proposed rental is about ...
1400/1988.13 · 100% = 70.4%
of his take-home pay.
Most financial planners would recommend the percentage be well below 50%. It is unlikely James can make his proposed monthly payments.

Add parentheses to make true 36 / 9 - 3 = 6
36/ (9 - 3) = 6
Cause:
9 - 3 = 6
Then:
36/6 simplified equals 6
So, your answer is 36/(9 - 3) = 6
Hope it helps! Good luck friend! :3
Answer:
36 / (9 - 3) = 6
Step-by-step explanation:
If you put the parentheses around 9 - 3, that will give you 6. 36 divided by 6 = 6. Also, in PEMDAS, Parentheses comes first, so that is why the parentheses go there to make this true.
