Answer:
b=6
Step-by-step explanation:
One of the kinds special triangles you learn about are the Pythagorean triples. These are right triangles with sides in certain ratios. One of them has sides in the ratios 3:4:5.
More generally, this triangle has sides in the ratio 3x:4x:5x
In your triangle, the ratio 8:10 corresponds to 4x:5x with x=2. Therefore, the remaining side is 3x with x=2, so
b=6

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Answers
Given:
Jake bought 3 drawing pens for $8.07.
Each pen costs the same amount.
To find:
How much did he spend for one pen?
Solution:
Let x be the cost of each pen. Then
Cost of three pens = 3x
Jake bought 3 drawing pens for $8.07.
[tex]3x=8.07[/tex]
Divide both sides by 3.
[tex]x=\dfrac{8.07}{3}[/tex]
[tex]x=2.69[/tex]
Therefore, he spend $2.69 for one pen.

Anyone can help me with math for solving for a side in the right triangles for khan academy
Answers
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

Jorge has 24 ounces of baking powder to use for baking loaves of bread. if each loaf of bread requires 1/4 of an ounce of baking powder, how many loaves of bread will Jorge be able to bake?
Answers
Answer:
96 loaves of bread
Step-by-step explanation:
Total baking powder = 24 ounces
Baking powder used per loaf of bread = 1/4 of an ounce
loaves of bread will Jorge be able to bake = Total baking powder / Baking powder used per loaf of bread
= 24 ÷ 1/4
= 24 × 4/1
= 96 loaves of bread
loaves of bread will Jorge be able to bake = 96 loaves of bread

Henry places £6000 in an account which pays 4.6% compound interest each year
Calculate the amount in his amount after 2 years
Answers
Answer:
£ 6,564.70
Step-by-step explanation:
Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years
Compound Interest formula =
A = P(1 + r/n)^nt
A = Final Amounrt
P = Principal = £6,000
r = Interest rate = 4.6%
t = Time in years = 2 years
n = Compounding frequency = Yearly = 1
First, convert R percent to r a decimal
r = R/100
r = 4.6%/100
r = 0.046 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 6,000.00(1 + 0.046/1)^(1×2)
A = £ 6,564.70
The amount in his account after 2 years = £ 6,564.70

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.
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?
Answers
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.

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the
exponential equation?
Answers
Sorry for tje late answer but it is 150 * 0.08^x
The exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].
What is depreciation?Depreciation is the rate by which the value of an object reduces with respect to time. it is given by the formula,
[tex]A = P(1-\dfrac{r}{100})^t[/tex]
where A is the value of object after t period of time, P is the principal amount, r is the rate of depreciation, and t is the time period.
We know the formula of the depreciation, Also, the initial value of the car is $15,000, and the rate of depreciation r that is 8% per year. Therefore, the function of the depreciation of the car can be written as,
[tex]A = P(1-\dfrac{r}{100})^t\\\\A = 15000(1-\dfrac{8}{100})^t\\\\A = 15000(1.08)^t[/tex]
Hence, the exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].

Answer:17/35
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(2/7, 1/5) = 35
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(2/7x5/5)+(1/5x7/7)=?
Complete the multiplication and the equation becomes
10/35+7/35=?The two fractions now have like denominators so you can add the numerators.
Then:10+7
——- =17/35

This fraction cannot be reduced.
Therefore:2/7+1/5=17/35
