Answer:
a=12
Step-by-step explanation:
We must use SOH, CAH, TOA
SOH= Sin0=opp/hyp
CAH=Cos0=adj/hyp
TOA= Tan0=opp/adj
Since we have opposite and hypotenuse we use Sin ratio, in this case,
sin30°= [tex]\frac{a}{24}[/tex]
[tex]\frac{1}{2}[/tex]=[tex]\frac{a}{24}[/tex] we cross multiply
[tex]\frac{2a}{2}[/tex]=[tex]\frac{24}{2}[/tex]divide both sides by 2 to get a by itself
a=12
Answer:
a = 12
Step-by-step explanation:
To find a, we will use the trigonometric ratio of Sin, since the opposite side of the angle given needs to be found out and the hypotenuse is given;
Sin(30) = [tex]\frac{a}{24}[/tex]
Sin(30) * 24 = a
12 = a

Mary is making a pinata that has a ball-like shape. The pinata has a surface area of
60 square feet. Use the formula for the surface area of a sphere:
S=471?
to find the radius of the pinata in feet.
Answer:
2.19 ft
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
Surface area of the sphere = 60 ft²
The formula to find the radius of a sphere
= √A/4π
= √60/4 × π
= 2.19 ft
Therefore, the radius of the pinata = 2.19 ft

giving brainliest and if u cant read down it says: if the spinner is spun 540 times throughout the day, how many dog or cat toys are expected to be given away? please help.
Answer:
324/540 cats and dogs should be expected to be given away
Step-by-step explanation:
First, write the fraction of the cats on the spinner plus the dogs on the spinner.
[tex]\frac{4}{10} + \frac{2}{10} = \frac{6}{10}[/tex]
Now, we have to make the denominator 540 but we have to make it equal so you divide.
540 ÷ 10 = 54
So, our fraction should look like this.
[tex]\frac{x}{540}[/tex]
Now, multiply 6 × 54 = 324
[tex]\frac{324}{540}[/tex] is our answer
Have a great day!
The dog or cat toys are expected to be given away = 378
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
If the spinner is spun 540 times throughout the day.
Total fraction of the cat and dogs together,
= 5/10+2/10
=7/10
Divide the 540 into 10 equal parts,
= 540/10
=54
let 'x' dog or cat toys are expected to be given away
So, x/540 = 7/10
x= 54*7
x= 378.
Hence, dog or cat toys are expected to be given away = 378/540

You are choosing between two plans at a health club. Plan A offers an initial membership fee of $75. And you pay $15 per month. Plan B offers an initial membership fee of $20 and you pay $26 a month. How many months are the two clubs the same price?
Answer:
5 months
Step-by-step explanation:
Let the number of months equalising both plans fee = x
Plan A total fee = 75 + 15x , Plan B total fee = 20 + 26x
Equalise both: 75+15x = 20+26x ; 75-20 = 26x-15x ; 55 = 11x ; x = 55 / 11
x = 5
Proof : 75 + 15 (5) = 20 + 26 (5) ; LHS 150 = RHS 150

An apple-juice container has a tiny hole in it, so it is slowly leaking. If the container leaks three
ounces every 19 minutes, how long will it take for the 16 ounces of juice in the container to leak
out? Write a proportional equation and solve with J.R.'s strategy of using a Giant One. 3 id
14
Answer:
101.33333 minutes
Step-by-step explanation:
Given :
Leakage rate = 3 ounces per 19 minutes
Time it'll take for 16 ounces of juice in the container to leak out
The leakage rate on ounce per minute :
3 ounces / 19 minutes = 0.1578947 ounce per min
1f 0.1578947 ounces leak out in 1 minutes
16 ounces will leak out in x minutes
Hence ;
0.1578947x = 16 ounces
x = 16 / 0.1578947
x = 101.33335 minutes
OR :
3 ounces = 19 minutes
1 ounce = (19 / 3) = 6.333333 minutes
16 ounces = (15 + 1) ounce
15 ounces = 3 * 5
Hence, 15 ounces will leak in (19 minutes * 5) = 95 minutes
1 ounce = 6.33333 minutes
Hence,
16 ounces will leak in (95 minutes + 6.33333 ounces) = 101.33333 minutes
HENCE, All 16 ounces will leak out in 101.33333 minutes

Express the following in the form a + bi, where a and b are real numbers:
[tex] \sqrt{60i - 11} [/tex]
The equivalent of the complex number expression is [tex]\sqrt{60i - 11}[/tex] is 2 + 15i
How to rewrite the expression?The complex number expression is given as:
[tex]\sqrt{60i - 11}[/tex]
Rewrite as:
[tex]a + bi = \sqrt{60i - 11}[/tex]
Take the square of both sides
[tex]a^2 + 2abi - b = 60i - 11[/tex]
By comparison, we have:
a^2 - b = -11
2ab = 60
Divide both sides by 2
ab = 30
Using a graphical tool, we have:
a = 2,b = 15
So, we have:
a + bi = 2 + 15i
