At a children's concert there were 80 boys. There were 1 1/2 times the number of girls as boys. What percentage of the total number of children at the concert were girl?
Answer:
60% are girls
Step-by-step explanation:
80 x 1.5 = 120 which is the amount of girls
120 out of 200 is 12/20 or 3.5 which is 60%

Tell whether the statement is always, sometimes, or never true. Explain.
1. If x and y are supplementary angles, then y is acute.
2. If x and y are complementary angles, then x is obtuse.
Answer:
1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.
2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.
Step-by-step explanation:
Answer:
1) Sometimes
2) Never
Step-by-step explanation:
1) you could have two angles add up to 180 degrees and one of them could be less than 90
example, x = 140° and y = 40°
2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles
Find the Value of x ( All help would be appreciated )
Answer:
Hello! answer: x = 31
Step-by-step explanation:
This whole thing Will equal 360 we can subtract that by 112 and another 112 because there are two because they are vertical angles so 112 + 112 = 224 360 - 224 = 136 now we divide by 2 since those last two angles will have the same measure 136 ÷ 2 = 68 so now we just have to find out what multiplied by 2 plus 6 = 68 so 2 × 31 = 62 and 62 + 6 = 68 so x = 31 hope that helps! and I showed a visual for you so hopefully this makes more sense!

Step-by-step explanation:
17) not sure where area is being shaded. so i can't help you with that one. if you could clarify i could edit this or send a separate answer for it
18) find the area of the two rooms. both have a 50x40 room so the total area is 4000 ft^2. But, there is an overlap so you need to subtract the aquarium once. the area of the aquarium is 30*5 = 150 ft^2. Subtract 4000ft^2 by 150 ft^2 and you get 3850 ft^2
solve for x -62=-15(x-1)+4
Answer:
[tex]x=4\frac{11}{15}[/tex]
Step-by-step explanation:
- 62 = - 15(x - 1) + 4
- 52 = - 15x + 15 + 4
- 52 = - 15x + 19
- 52 - 19 = - 15x + 19 - 19
- 71 = - 15x
- 15x ÷ - 15 = - 71 ÷ - 15
[tex]x = \frac{71}{15}[/tex]
[tex]x=4\frac{11}{15}[/tex]

Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters. How tall is the hotel on Squidward’s drawing?
Answer:
10 m building in Patrick's drawing would be of 0.5 cm
Step-by-step explanation:
Scale of Patrick's drawing is
1 inch = 10 meters
or 2.54 cm = 10 meters
1 cm = 3.94 m
In case of Squidward the scale is 2 cm = 40 meters or
1 cm = 20 meters
So a 10 m building in Patrick's drawing would be of
0.5 cm
Answer:
13.5
Step-by-step explanation:
Given: Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters.
To find: How tall is the hotel on Squidward’s drawing?
Formula: Height of the building = y × tan x + measurer's height
Solution: The height of the building is calculated by using the formula. y = distance of the measurer from the building. x = the angle measured from the clinometer.

Answer:(200,12000)
Step-by-step explanation:
Here are two stories: The initial freshman class at a college is 10% smaller than last year’s class. But then during the first week of classes, 20 more students enroll. There are then 830 students in the freshman class.
A store reduces the price of a computer by $20. Then during a 10% off sale, a customer pays $830
here are two equations: 0.9x+20=830, 0.9(x-20)=830
A. Decide which equation represents each story.
B. Explain why one equation has parentheses and the other doesn't.
C.Solve each equation, and explain what was the solution means in the situation.
Thank you to the people that answered my questions!
Using proportions, it is found that:
a. The equations are related to the stories as follows:
0.9x+20=830 = Class in college.0.9(x-20)=830 = Computer price.b. The parenthesis is because of the 10% reduction was applied over the value subtracted by $20.
c. The solutions are given as follows:
x = 900: Size of the freshmen class in the previous year.x = 942: Original price of the computer.What is a proportion?A proportion is a fraction of a total amount, and are used along with basic arithmetic operations such as multiplication or division to find the desired measures in the context of a problem.
One example of application of proportions is for percentage problems, as the decimal equivalent of the percentage, considering discounts or increases, is multiplied by the total amount to find the equivalent amount.
For the college class, we have that:
It is 10% smaller than last year's amount of x, that is, 90% of x = 0.9x.Then 20 is added to this amount, that is, 0.9x + 20.The equivalent amount is of 830 students, hence the equation is:
0.9x + 20 = 830
The solution is found as follows:
0.9x = 810
x = 810/0.9
x = 900.
Which is the size of the freshmen class in the previous year.
For the computer in the store, we have that:
The price of x was reduced by $20, hence x - 20.Over the price reduced by $20, a reduction of 10% was applied, hence the price paid is of: 0.9(x - 20).This price is of 830, hence the equation is:
0.9(x - 20) = 830
The solution, which is the initial price of the computer, is found as follows:
x - 20 = 830/0.9
x = 20 + 922
x = 942.
