If 4 out of 5 People at the picnic are children and there are 24 children at the picnic,many adults are there?
Answer:
6
Step-by-step explanation:
4/5 of the people at the picnic are children. There are 24 children. So 24 is 4/5 of the whole. You ÷4 to find 1/4. This is 6. So you add on the 6 as 1/4 add 4/5 equals the whole number of people there are at the picnic, 5/5. 24 add 6 is 30 so there are 30 le e at the picnic, and 6 adults.
Find the value of x?
Answer:
In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.

Answer:
See below.
Step-by-step explanation:
We have:
[tex]\frac{\sqrt3}{\sin(\theta)}=2[/tex]
And we want to find two different angles between 0 and 180 that satisfy this equation.
First, let's get our sine out of the denominator. Notice that this is the same as:
[tex]\frac{\sqrt3}{\sin(\theta)}=\frac{2}{1}[/tex]
Cross-multiply:
[tex]2\sin(\theta)=\sqrt{3}[/tex]
Divide both sides by 2:
[tex]\sin(\theta)=\frac{\sqrt{3}}{2}[/tex]
Here you go! I'll have the answer for you if you scroll down, so check it when you're ready!
#2 is correct. However, double check #3. The answer's down there too... :)
[Blank space...]
[More blank space...]
[And more...]
Answer for 1)
We have:
[tex]\sin(\theta)=\sqrt{3}/2[/tex]
So, at what points between 0 and 180 does sine equal √3/2?
If we refer to the unit circle, we can see that this happens twice: at 60.
Thus, the second time it occurs will be at 180-60 or 120.
So:
[tex]\theta=60\textdegree\text{ or } 120\textdegree[/tex]
Answer for 3)
So you are correct for the first three. So:
[tex]\sin(54)=t[/tex]
However, sine stays positive. So, our angle must be between 0 and 180.
So, instead of 180+54, it should be 180-54, giving us:
[tex]\sin(54)=\sin(126)=t[/tex]

Step-by-step explanation:
2h = W-3p
(solve for p)
Answer:
p = (2h-W)/-3
Step-by-step explanation:
2h - W = -3p
divide both sides by -3
(2h-W)/-3 = p
The value of p is w/3 - 2h/3.
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S
Given:
2h = W-3p
For p move w
2h - w = -3p
Now, divide both side by 3
2h/3 - w/3 = -3p/3
2h/3 - w/3 = -p
p= w/3 - 2h/3
Hence, the value of p is w/3 - 2h/3.

Large and small cans of peanuts were sold at a school fundraiser. One student sold
three small cans and nine large cans of peanuts for a total of $75. Another student
sold five small cans and seven large cans of peanuts for a total of $69. What is the
cost of the small and large cans of peanuts?
A Small can for $6.29 and large can for $7.00
B Small can for $4.86 and large can for $6.00
C Small can for $4.00 and large can for $7.00
D Small can for $7.00 and large can for $9.00
Answer:
the answer is c.
Step-by-step explanation:
4 x 5 + 7 x 7 = 69
4 x 3 + 7 x 9 = 75
Cost is small can for $4.00 and large can for $7.00.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Let S be the number of small cans and L be the number of large cans.
According to the question,
One student sold three small cans and nine large cans of peanuts for a total of $75.
That means the equation is ;
3S + 9L = 75 {equation 1}
And similarly for another student;
5S + 7L = 69 {equation 2}
Now we have two system of the equation.
3S + 9L = 75 {equation 1}
5S + 7L = 69 {equation 2}
Using elimination process,
we multiply 5/3 to equation 1,
5S + 15L = 125
And subtract equation 1 to the equation 2,
we get L = 7 and S = 4
Therefore, small can for $4.00 and large can for $7.00

Alan purchased 16 shares of company stock for $390.40. A month later, the total value of his shares fell to $291.20. What is the current price per share if each share costs the same?
A.
$6.20
B.
$18.20
C.
$24.04
D.
$24.40
Answer: $18.20
Step-by-step explanation:
390.40/16 to find the initial costs of the shares. That would be $24.40 per share. However, since the stock has fallen, you would do that same division, but with the new value. 291.20/16, which is $18.20
Answer:
$18.20 per share is the value of each stock currently
Step-by-step explanation:
Take the value the stocks are worth now and divide by the number of shares
291.20/16
$18.20 per share
$18.20 per share is the value of each stock currently

Convert 6 ounces into grams. Round your answer to the nearest whole
number.
Answer:
170
Step-by-step explanation:
You have to multiply the amount of ounces you want converted by 28.35. Then you have your ounces converted to grams.
If you use this formula then you would have, 170 X 28.35 = 170.1
When you round 170.1 to the nearest whole number you will get 170.
The conversion of 6 ounces into grams is 170 grams.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number.
Multiply the number of ounces you want to be converted by 28.35. Use the conversion.
1 ounces = 28 .35 grams
6 ounces = 6 x 28.35 grams
6 ounces = 170 grams.
Hence, 6 ounces is equal to 170 grams.

X = 10/ 5/6
When dividing a number by a fraction flip
The fraction over and multiply:
X = 10 x 6/5
Simplify
X = (10x6)/5
X = 60/5
X = 12
The answer is x = 12
Answer:
[tex]\boxed {x = 12}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]\frac{5}{6}x + 7 = 17[/tex]
-Subtract both sides by [tex]7[/tex]:
[tex]\frac{5}{6}x + 7 - 7 = 17 - 7[/tex]
[tex]\frac{5}{6}x = 10[/tex]
-Multiply both sides by [tex]\frac{6}{5}[/tex], which is the reciprocal of [tex]\frac{5}{6}[/tex]:
[tex]x = 10 \times (\frac{6}{5})[/tex]
[tex]x = \frac{10 \times 6}{5}[/tex]
[tex]x = \frac{60}{5}[/tex]
-Divide [tex]60[/tex] by [tex]5[/tex]:
[tex]x = \frac{60}{5}[/tex]
[tex]\boxed {x = 12}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]12[/tex].
