Given tan A =7/24, find the sin B and tan b. A. 7/25 B. 24/7 C. 24/25 D. 7/24
Question:
Given tan B =7/24, find the sin B
Answer:
Option A
[tex]sin\ B = \frac{7}{25}[/tex]
Solution:
Given that,
[tex]tan\ B = \frac{7}{24}[/tex]
We have to find sin B
We know that by trignometric ratios,
[tex]tan = \frac{opposite}{adjacent}[/tex]
From given,
[tex]tan\ B = \frac{7}{24}[/tex]
On comparing we get,
Opposite = 7
Adjacent = 24
We can find the hypotenuse
[tex]hypotenuse^2 = opposite^2 + adjacent^2\\\\hypotenuse^2 = 7^2 + 24^2\\\\hypotenuse^2 = 49 + 576\\\\hypotenuse^2 = 625\\\\Take\ square\ root\ on\ both\ sides\\\\hypotenuse = 25[/tex]
Thus Sin B is given as:
[tex]sin\ B = \frac{opposite}{hypotenuse}\\\\sin\ B = \frac{7}{25}[/tex]
Thus, sin B is [tex]\frac{7}{25}[/tex]
Write an equation for h.
Answer:
h = 96/8
Step-by-step explanation:
In this image, we're being shown a rectangle. To solve for a rectangle, you use:
Area = base x height
We know the base and area already, so we can plug those values in. It will then look like this:
96 ft = 8ft x height
In order to make it into "h = _____" we need to isolate the height. We can use inverse operation for that. We can divide 8 on both sides. This will then give us the equation:
h = 96/8
Hence, the answer to this is "h = 96/8". If you have any further concerns or questions, feel free to leave a comment below! Have a great day!!! :)

There are 5 pennies for every 6 quarters in Ahmed's pocket. Could Ahmed have a total of 30 coins in his pocket? Explain
Ahmed cannot have total of 30 coins in his pocket
Solution:
Given that,
There are 5 pennies for every 6 quarters in Ahmed's pocket
We are asked if Ahmed can have a total of 30 coins in his pocket
From given,
5 pennies for every 6 quarters
Therefore, ratio is:
penny : quarter = 5 : 6
Total = 5 + 6 = 11
Then the total number of coins must be multiple of 11
But 30 is not a multiple of 11
Therefore, Ahmed cannot have total of 30 coins in his pocket
No, Ahmed cannot have a total of 30 coins in his pocket.
Explanation:Yes, Ahmed could have a total of 30 coins in his pocket.
To determine how many quarters and pennies Ahmed could have, we can set up a ratio.
The ratio of pennies to quarters is 5:6.
Let the number of quarters be represented by 6x, where x is a positive integer. Then, the number of pennies would be 5x.
To find out if Ahmed could have a total of 30 coins, we need to solve the equation 6x + 5x = 30.
Combining like terms, we obtain 11x = 30. By dividing both sides of the equation by 11, we find that x = 2.7272 (repeating).
Since x must be a positive integer, we can conclude that Ahmed cannot have a total of 30 coins in his pocket.

Amy has a collection of marbles in three sizes, small, medium, and large. She has five times as many small marbles as medium marbles. The number of large marbles is two more than three times the number of medium marbles.
Let x represent the number of medium marbles Amy has. Write an algebraic expression to represent the number of small marbles she has.
Write an algebraic expression to represent the number of large marbles she has.
If Amy has a total of 560 marbles, how many of each size does she have? Show your work.
Answer:
Amy has 310 small marbles, 62 medium marbles and 188 large marbles.
Step-by-step explanation:
i) Let the number of small marbles be x
ii) let the number of medium marbles be y
iii) let the number of large marbles be z
iv) Amy has 5 times as many small marbles as medium marbles therefore we can write 5y = x
v) the number of large marbles is two more than than three times the number of medium marbles therefore we can write
z = 3y + 2
vi) Amy has a total of 560 marbles therefore we can write x + y + z = 560
vii) Therefore from i) we can write x = 5y
viii) using vii) and v) in vi) we can write
x + y + z = 5y + y + 3y + 2 = 560
ix) Therefore 9y = 558 .... therefore y = [tex]\frac{558}{9}[/tex] = 62
x) Therefore from i) we get x = y [tex]\times[/tex] 5 = 62 [tex]\times[/tex] 5 = 310
xi) Therefore z = (3 [tex]\times[/tex] 62) + 2 = 188
Amy has 310 small marbles, 62 medium marbles and 188 large marbles.

16^(3-3r)=256 can someone please help me solve this!! Thanks!!
Answer:
The value of r is 1/3
Step-by-step explanation:
Let's solve for r in the equation:
16 ^(3-3r) = 256
16 ^(3-3r) = 16²
3 - 3r = 2
-3r = 2 - 3
-3r = -1
r = -1/-3
r = 1/3
Let's prove r = 1/3 is correct:
16 ^(3-3r) = 256
16 ^ (3 - (3 * 1/3)) = 256
16 ^ (3 - 1) = 256
16 ² = 256
16 * 16 = 356
We proved that r = 1/3 is correct
You have two fair, six-sides dice. However, the dice have been modified so that instead or 1,2,3,4,5,6 the sides are numbered 1,2,2,2,3,4.
What is the probability the total of the two dice is an even number?
Answer:
.
Step-by-step explanation:
Answer:
5/9.
Step-by-step explanation:
Prob ( first dice = 2 and second = 2) = 1/2 * 1/2 = 1/4
Prob ( first = 2 , second = 4) = 1/2 * 1/6 = 1/12
Prob ( first = 4 and second = 2) = 1/12.
Prob ( first = 3 and second = 1 ) = 1/36
Prob ( first = 1 and second = 3) = 1/36.
Prob ( first = 3 and second = 3) = 1/6 *1/6 = 1/36.
Prob (first = 1 and second = 1 = 1/36.
Prob (first = 4 and second = 4 = 1/36.
Required probability is the sum of these which is:
5/9.

Summer exercises for 0.5 hour on Monday Wednesday and Friday each week. How many hours will she exercise in four weeks
Answer:
She will exercise for 6 hours in four weeks.
Step-by-step explanation:
Summer exercises for 0.5 hour on Monday, 0.5 hour on Wednesday, and 0.5 hour on Friday. There are 3 days where she exercises for 0.5 hour.
3 days X 0.5h = 1.5h each week
For four weeks, multiply the hours each week by 4.
1.5h X 4 weeks = 6h
Therefore Summer will exercise for 6 hours over the course of 4 weeks.
Answer:
6 hours
Step-by-step explanation:
We know that Summer exercises for 0.5 (Or a half) hour every day, three days a week (Monday, Wednesday, Friday). We need to found out how many hours she exercises in 4 weeks.
To solve this we first find out how many hours she exercises in one week. To do so, we set up an equation like this:
(Time exercising) x (# of days exercising) = (Hours spent exercising in one week)
Plug in the given numbers:
0.5 x 3 = 1.5 hours
If we know she exercises 1.5 (Or one and a half) hours in 1 week, we multiply this number by 4 to find out how many hours she exercises in 4 weeks. This can be shown in an equation like this:
1.5 x 4 = 6
So Summer will exercise for 6 hours in 4 weeks.

will the account balance be aller 17 years!
3) Ashley invests $4,650 in a savings
account with a fixed annual interest rate of
9% compounded 12 times per year. What
will the account balance be after 12 years?
Answer:
Account balance after 17 years: $21,352.27
Step-by-step explanation:
Use the formula for amount after compound interest.
A = P(1+i)ⁿ
What the variables mean:
"A" is for amount after the time period.
"P" is principal, meaning starting money.
"i" is the interest per compounding period.
"n" is the total number of compounding periods.
"c" is the compounding periods each year. (annual = 1; monthly = 12, etc)
To calculate "i":
i = r/c
"r" is the annual interest rate in decimal form.
To calculate "n":
n = t*c
"t" is the time, usually the number of years.
Now can combine these formulas:
[tex]A = P(1+\frac{r}{c})^{t*c}[/tex]
What do we know from the problem?
t = 17 years
P = 4650
r = 9% = 0.09
c = 12
Substitute them into the formula.
[tex]A = P(1+\frac{r}{c})^{t*c}[/tex]
[tex]A = 4650(1+\frac{0.09}{12})^{17*12}[/tex] Simplify
[tex]A = 4650(1.0075)^{204}[/tex] Do the exponent with a calculator
[tex]A = 4650(4.59188689)[/tex] Multiply
[tex]A = 21352.274[/tex] Unrounded answer
A ≈ 21352.27 Round down because "4" is less than 5.
Therefore Ashley's account balance after 17 years will be $21,352.27.
