Answer:
120 girls attended the school play. :)
Step-by-step explanation:
there are 200 children.
40% are boys.
this means 60% are girls.
60% + 40% = 100%
60% of 200 is 120
Answer:
120 Girls attended the school play.
Step-by-step explanation:
We know that 40% of 100 is 40, so you double that and get 40% of 200 is 80.
Then you do 120-80=40.

What are the measures of the other three angles formed by the intersection?
Answer:
1 = 130
2 = 50
3 = 130
Step-by-step explanation:
Since we already know that one angle is 50 degrees, this also tells us that angle two is congruent to it because it is opposite to it. Now the two other adjacent angles, basically just do 180-50 to get 130.

How does this create two “congruent” right angle triangles when i thought it had to be similar in 3 ways to be congruent
Though these segments aren't marked congruent in the diagram, the two lines inside the circle making up the bases of the triangles are congruent as all radii are congruent. So the triangles are congruent by SAS.
students at franklin middle school were serveyed to find where they spent there summer vacation .the graph below represents the data from 80 students.
how many more students surveyed spent their summer vacation in californa than number of students who spent their summer vacation in colorado?
Answer:
B. 4 people
Step-by-step explanation:
In total, there are 80 students, so the number of people who spent their vacation in california is 25% of 80, which is 20 people.
For the number of people who went to Colorado, it is 20% of 80, which is 16.
20-16 = 4 people

3x + 5 = 5x - 29
Solve these for X.
Answer:
x=17!
Step-by-step explanation:
3x+5=5x-29
5=2x-29
34=2x
Therefore x=17!
Answer:
x = 17
Step-by-step explanation:
Lets start evaluating
3x + 5 = 5x - 29
3x + 5 + 29 = 5x
3x + 34 = 5x
34 = 5x - 3x
34 = 2x
x = 34/2
x = 17

Yes, Frank does have enough, he has 250 metal and only has 228 surface area.
Step-by-step explanation:
You take all the triangles (4) and multipy 4 x 6 (24) then divide that by 2 (12) so now you know all the triangles are equal to 12. Then the squares, you multiply 6 x 6 (36) now you know all the squres are equal to 36 and then you add 12 + 12+12+12+36+36+36+36+36 and then you get 228.
in a class room 1/6 of students are wearing blue shirts 2/3 are wearing white shirts there are 12 students how many are wearing shirts other than blue shirts?
Answer:
4 students
Step-by-step explanation:
what we know: 12 students, 2/3 are wearing blue, 1/6 are wearing red
first you have to make the fractions have the same denominator(2/3=4/6)
theres also 1/6 that are not wearing blue or red (1/6+4/6=5/6, 6/6-5/6=1/6)
so that makes it 2/6 of the students not wearing blue(1/6+1/6=2/6)
simplify(2/6=1/3)
1/3 of 12 is 4 (12÷3=4)
the equations are in parentheses and bolded, italicized, underlined.

Quadrilateral WILDWILDW, I, L, D is inscribed in circle OOO. \overline{WI} WI start overline, W, I, end overline is a diameter of circle OOO. What is the measure of \angle D∠Dangle, D?
Answer:
135degrees
Step-by-step explanation:
Find the diagram attached.
Note that in a cyclic quadrilateral, the sum of the opposite side of the quadrilateral is 180degrres.
According to the diagram shown:
<D+<I = 180
<D+45 = 180
Subtract 45 from both sides
<D+45-45 = 180-45
<D = 180-45
<D= 135°
Hence the measure of <D is 135degrees
Answer: 135

If you spin the spinner 11 times, what is the best prediction possible for the number of times it will land on yellow?
Answer:50%
Step-by-step explanation:
The mean of 12 numbers is 20 and the mean of another 8 numbers is 25 find the mean of the 20 numbers
Answer:
22
Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Given the mean of 12 numbers is 20 , then
[tex]\frac{sum}{12}[/tex] = 20 ( multiply both sides by 12 )
sum = 240
Given the mean of 8 numbers is 25 , then
[tex]\frac{sum}{8}[/tex] = 25 ( multiply both sides by 8 )
sum = 200
Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is
mean = [tex]\frac{440}{20}[/tex] = 22

Step-by-step explanation:
Victor sold cupcakes and cookies yesterday. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the
day, Victor had sold $95.25 worth of cookies and cupcakes. If he sold 68 cupcakes and cookies combined, how many
cupcakes were sold and how many cookies were sold?
answer:number of cupcakes sold is 13 Number of cookies sold is 27
Step-by-step explanation:
Let x represent the number of cupcakes that Victor sold. Let y represent the number of cookies that Jane sold. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day, This mean Victor had 2.25x 0.5y = 42.75 - - - - - - - - - -1she sold 40 cupcakes and cookies combined, it means thatx y = 40Substituting x = 40 - y into equation 1, it becomes2.25(40 - y) 0.5y = 42.7590 - 2.25y 0.5y = 42.75- 2.25y 0.5y = 42.75 - 90- 1.75y = - 47.25y = - 47.35/-1.75y = 27x = 40 - yx = 40-27 = 13
An equation is formed when two equal expressions. The number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of cupcakes sold be represented by x, while the number of cookies sold is represented by y.
Now, the total number of cupcakes and cookies sold combined is equal to 68. Therefore, the equation can be written as
x + y = 68
x = 68 - y
Also, Each cupcake sold for $2.25 and each cookie sold for $0.50. And the total sale that Victor made is of $95.25. Therefore, the equation can be written as,
2.25x + 0.50y = 95.25
2.25(68 - y) + 0.5y = 95.25
153 - 2.25y + 0.5y = 95.25
-2.25y + 0.5y = 95.25 - 153
1.75y = 57.75
y = 33
Now, substitute the value of x in the first equation.
x + y = 68
x + 33 = 68
x = 35
Hence, the number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

Answer:
100
Step-by-step explanation:
Find the area of the figure. Round to the nearest tenth
Answer:
Find the area of each triangle and then add it up. As you are aware, to find the area of a triangle the equation is B times Height divided by 2. And to make it easier do the top left triangle and the top right triangle, add them together and then divide that by 2.
Step-by-step explanation:
3 time 5 equals 15 divided by 2 equals 7.5
5 times 8 equals 40 divided by 2 equals 20
7.5 plus 20 equals 27.5
27.5 times 2 equals 55
therefor your answer should be 55m

A student made an 85% on a test with 25 questions. What is the number
of questions that the student answered correctly? Round to the nearest
whole number*
The student answered 21 questions correctly on a test.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
Since the student made an 85% on a test with 25 questions.
To determine the number of questions the student answered correctly, we need to multiply the number of questions by the percentage of questions answered correctly, which is 85%.
= 25 questions × 0.85
Apply the multiplication operation, and we get
= 21.25
Rounding to the nearest whole number,
= 21 questions

9x-4 / (x²-4)
Step-by-step explanation:
common denominator is 'x²-4' which is (x-2)(x+2)
the term '7x' already has that denominator but 2/x+2 becomes 2(x-2)/(x²-4)
now you can add 7x to 2(x-2) which is 7x + 2x - 4 or 9x-4 and
