At the city museum, child admission is $6.40 and adult admission is $9.90. On Saturday, twice as many adult tickets as child tickets were sold, for a total sales of $733.60. How many child tickets were sold that day?
Answer:
x child tickets, y adult tickets
6.40x+9.50y=1260.70
x+y=150
64x+95y=12607
x+y=150
If you solve this, you have to get x=53, y= 97.
So 53 child tickets and 97 adult tickets

\( - 3 \frac{3}{4} - x = -6 \frac{1}{6} \)
THIS IS MATH FOR 7TH GRADE!!
Answer:
\(x=2\frac{5}{12}\)
Step-by-step explanation:
Given equation:
\(-3\frac{3}{4}-x=-6\frac{1}{6}\)
Begin by adding x to both sides of the equation:
\(-3\frac{3}{4}-x+x=-6\frac{1}{6}+x\)
\(-3\frac{3}{4}=-6\frac{1}{6}+x\)
Add -6¹/₆ to both sides of the equation:
\(-3\frac{3}{4}+6\frac{1}{6}=-6\frac{1}{6}+x+6\frac{1}{6}\)
\(-3\frac{3}{4}+6\frac{1}{6}=x\)
Swap sides:
\(x=6\frac{1}{6}-3\frac{3}{4}\)
Rewrite the mixed numbers as improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:
\(x=\dfrac{6 \times6+1}{6}-\dfrac{3 \times 4+3}{4}\)
\(x=\dfrac{36+1}{6}-\dfrac{12+3}{4}\)
\(x=\dfrac{37}{6}-\dfrac{15}{4}\)
When subtracting fractions, we must ensure that they have the same denominator. To do this, find the least common multiple (LCM) of the two denominators.
As 6 and 4 are factors of 12, then 12 is the LCM.
Rewrite the fractions as their equivalent fractions (with a denominator of 12) by multiplying the numerator and denominator by the same number.
\(x=\dfrac{37\times 2}{6\times 2}-\dfrac{15\times3}{4\times3}\)
\(x=\dfrac{74}{12}-\dfrac{45}{12}\)
Now the fractions all have the same denominator, we can simply subtract the numerators:
\(x=\dfrac{74-45}{12}\)
\(x=\dfrac{29}{12}\)
Finally, convert the improper fraction into a mixed number:
\(x=\dfrac{24+5}{12}\)
\(x=\dfrac{24}{12}+\dfrac{5}{12}\)
\(x=2+\dfrac{5}{12}\)
\(x=2\frac{5}{12}\)

A quadrilateral has two angles that measure 235° and 40°. The other two angles are in a ratio of 5:12. What are the measures of those two angles?
Answer: Let's denote the two unknown angles as x and y.
We know that the sum of the angles in any quadrilateral is 360°, so we can set up an equation using this fact:
235° + 40° + x + y = 360°
Simplifying this equation, we get:
x + y = 85° (equation 1)
We also know that the other two angles are in a ratio of 5:12. This means that:
x/y = 5/12
Multiplying both sides by y, we get:
x = (5/12)y (equation 2)
Now we can substitute equation 2 into equation 1 and solve for y:
(5/12)y + y = 85°
(17/12)y = 85°
y = (12/17) * 85°
y = 60°
Substituting y = 60° into equation 2, we can solve for x:
x = (5/12) * 60°
x = 25°
Therefore, the two angles that are in a ratio of 5:12 measure 25° and 60°, respectively.

Answer: x = \(4\sqrt{13}\)
Step-by-step explanation:
We can use the Pythagorean theorem to help us solve, where a and b are the legs and c is the hypotenuse.
Given:
a² + b² = c²
Substitute known values:
9² + x² = 17²
Square:
81 + x² = 289
Subtract 81 from both sides:
x² = 208
Square root of both sides:
x = \(\sqrt{208}\)
Divide into factors:
x = \(\sqrt{16*13}\)
Square root of 16:
x = \(4\sqrt{13}\)
Answer:
\(4\sqrt{13}\)
Step-by-step explanation:

What is the rate that brand a is selling for? Give the rate and then specify the unit rate.Need this fast
1. The rate that Brand A is selling for is A) 10-unit rate.
2. The unit rate of Brand A is $0.10 per pound.
What is the unit rate?The unit rate refers to the variable cost per unit or the quotient of a division operation.
The unit rate shows a value's ratio in relation to another.
To compute the unit rate, we can use the division operation that makes the denominator the dividend, which is divided by the numerator (or divisor).
The quantity in Brand A = 20 pounds
The quantity in Brand B = 60 pounds
Cost of Brand A = $2
Cost of Brand B = $5
The unit rate for Brand A = $2/20 = $0.10, which can also be expressed as 10 units for $1 (20/$2).
Likewise, the unit rate for Brand B = $5/60 = $0.83, which we can describe as 12 units for $1 (60/$5).
Thus, we can conclude that the rate at which Brand A is selling is Option A.

A spherical balloon is inflated so that its volume is increasing at the rate of 3 cubic feet per minute. How fast is the radius of the balloon increasing when the radius is 2 feet?
The rate at which the spherical balloon's radius is increasing is
3/16π ft/min when the volume is increasing at the rate of 3 ft³/min.
Given, a spherical balloon is inflated so that its volume is increasing at the rate of 3 cubic feet per minute.
we have to find that how fast is the radius of the balloon increasing when the radius is 2 feet.
as, we know the volume of the balloon be,
V = 4/3πr³
now we have to find the rate of change of radius,
On differentiating both the sides with respect to time, we get
V' = 4/3π(3r²)dr/dt
V' = 4πr²dr/dt
as, the rate of change of volume of the balloon be, 3 ft³/min
V' = 3
3 = 4πr²dr/dt
dr/dt = 3/4πr²
Now, on putting r = 2, we get
dr/dt = 3/4π(2)²
dr/dt = 3/16π
so, the radius of the balloon increase at the rate of 3/16π.
Hence, the radius of the balloon increase at the rate of 3/16π.

Explanation
we can easily solve this by using a rule of three
Step 1
Let
actual price(2020)=price of 2019 + 2%
so
actual price(2020)= 102 % and
price ( 2019)=100 %
let x represents the cost for 2019, so
\(\begin{gathered} \text{if} \\ 122\Rightarrow\text{ 102\%} \\ x\text{ }\Rightarrow\text{ 100 \%} \end{gathered}\)the proportion would be
\(\begin{gathered} \frac{122}{102\text{ \%}}=\frac{x}{100\text{ \% }} \\ \text{ Multiply both sides by 100 \%} \\ \frac{122}{102\text{ \%}}\cdot100=\frac{x}{100\text{ \% }}\cdot100 \\ 119.607=x \end{gathered}\)therefore, the cost in January of 2019 is
