Answer:
x = 7, y = 8
Step-by-step explanation:
Knowing y = 8, we can substitute into equation and solve:
8 = x + 1
- 1 - 1
7 = x
Y is given, X is solved. Therefore:
x = 7, y = 8

For which type of triangle below would a circumcircle whose diameter coincides with one
side of the triangle?
Answer:
right triangle
Step-by-step explanation:
A circumcircle of a polygon is a circle that passes through all the vertices of the polygon.
If the diameter of the circle is one side of the triangle, then the triangle is in the semicircle.
The angle at the circumference in a semicircle is a right angle.
Therefore, the answer is right triangle

Selena buys several shares of stock at $32 per share and sells them at $28. 32 per share. What is the percent of decrease in the price of the stock? 12. 0% 11. 5% 11. 0% 10. 5%.
The total percent of decrease in price of the shares of Selena's stock which Selena first buys and then sold is 11.5 percent.
What is percentage decrease?Percentage decrease in a number is the ratio of total decrease in the original value of a number to the decreased value in the percentage form.
Given information-
The total stock buy by the Selena in $32.
The total stock sold by the Selena in $28.32.
As the total stock buy by the Selena in $32, and the total stock sold by the Selena in $28.32. Thus the total decrease in the price of stock is,
[tex]C_s=32-28.32\\C_s=3.68[/tex]
Thus the total decrease in the price of stock is $3.68.
As the cost price of the stock is $32 and the total decrease in the price of stock is $3.68. Thus the total percent of decrease in the price of the stock is,
[tex]\Delta C_s=\dfrac{3.68}{32}\times100\\\Delta C_s=11.5[/tex]
Thus the total percent of decrease in the price of the stock is 11.5 percent.

A hand glider dives at 25 mph in a direction 60° below horizontal. What is the component form of the velocity vector?.
Velocity can be represented in horizontal and vertical components
The horizontal component form of the velocity is 12.5 mph
How to determine the component form of the velocityThe given parameters are:
Velocity = 25 mph
Angle = 60 degrees
The horizontal component form of the velocity is then calculated as:
[tex]v_x = 25 * \cos(60)[/tex]
Evaluate the product
[tex]v_x = 12.5[/tex]
Hence, the horizontal component form of the velocity is 12.5 mph

Type the correct answer in the box. The solubility of calcium carbonate is 14. This rate means that 14 milligrams of calcium carbonate can dissolve in 1 liter of water. How much water would be required to fully dissolve 11 grams of calcium carbonate? Express your answer to the correct number of significant figures. One milligram is equal to 0. 001 grams. It would take liters of water to fully dissolve 11 grams of calcium carbonate.
Ratio compares two quantities. The amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.
Given to us
The solubility of calcium carbonate is 14.
We know that to dissolve 14 milligrams of calcium carbonate we will need 1 liter of water. therefore, the ratio of water and calcium carbonate can be written as,
[tex]\rm \dfrac{calcium\ carbonate}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]
We need to find the amount of water needed to dissolve 14 grams of water, therefore, we will convert grams to milligrams,
1 gram = 1000 milligram
14 gram = 14,000 milligram
Using the same ratio,
[tex]\rm \dfrac{14,000\ milligram}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]
[tex]\rm {water} = \dfrac{14000\ milligram \times 1\ liter}{14\ milligram}[/tex]
water = 1000 liters
Hence, the amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.

A particular type of diet cola advertises that each can contains 12 ounces of the beverage. Each hour, a supervisor selects 10 cans at random, measures their contents, and computes a 95% confidence interval for the true mean volume. For one particular hour, the 95% confidence interval is 11.97 ounces to 12.05 ounces.
a. Does the confidence interval provide convincing evidence that the true mean volume is different than 12 ounces? Explain your answer.
b. Does the confidence interval provide convincing evidence that the true mean volume is 12 ounces? Explain your answer.
According to the given confidence interval, we have that:
a) Since 12 ounces is part of the confidence interval, the interval does not provide convincing evidence that the true mean volume is different than 12 ounces.
b) Since 12 ounces is part of the confidence interval, the interval provides convincing evidence that the true mean volume is 12 ounces.
What is the hypothesis tested?It is being tested if the true mean volume is different of 12 ounces, hence:
If the confidence interval contains 12 ounces, it provides convincing evidence that the true mean volume is 12 ounces.If the confidence interval does not contain 12 ounces, it provides convincing evidence that the true mean volume is not 12 ounces.In this problem, the interval is (11.97, 12.05), hence it provides convincing evidence that the true mean volume is 12 ounces, and basically, item a is False and item b is True.

Claudia school is selling tickets to a spring musical. On the first day of tickets sales the school sold 3 senior citizen tickets and 9 child tickets for a total of 75$ The school took in 67 on second day by selling 8 senior citizen tickets and 5 child tickets.what price each of one senior citizens ticket and one child ticket
Answer:
One senior citizen ticket costs 4 dollars and one child ticket costs 7 dollars
Step-by-step explanation:
Let x be the cost of a senior ticket and y be the cost of a child ticket then...
3x+9y=75
8x+5y=67
We can simplify the first equation by dividing everything by 3...
x+3y=25
Now, isolate x by subtracting 3y from both sides
x=25-3y
We can solve this system of equations using substitution (substitute 25-3y for x)...
8(25-3y)+5y=67
200-24y+5y=67
Combine like terms
-19y+200=67
Subtract 200 from both sides
-19y=-133
Divide both sides by -19
y=7
Plug 7 back in for y to solve for x
x=25-3(7)=25-21=4

The quotient of a number and -7,
decreased by 2, is 10. Find the
number.
Answer:
-84
Step-by-step explanation:
Let the number be x. Then we have,
[tex]\frac{x}{-7}[/tex] (the quotient of a number and -7)
[tex]\frac{x}{-7}-2[/tex] (decreased by 2)
[tex]\frac{x}{-7}-2=10[/tex] (is 10)
Now we can solve for x,:
[tex]\frac{x}{-7}-2=10[/tex]
[tex]\frac{x}{-7}=12[/tex]
[tex]x=-84[/tex]
So, the original number is -84
Answer:
-84
Step-by-step explanation:
[tex]\frac{n}{-7}[/tex] -2 = 10
add 2 to each side to get:
[tex]\frac{n}{-7}[/tex] = 12
multiply each side by -7 to get:
n = -84

pennants and how many flags did they sell?
Given :
The 8 grade class is selling pennants and flags.They earn $1 for each pennantsold and $6 for each flag sold. They sell 50 items and earn $115.To Find :
How many pennants and how many flags did they sell?Solution :-
Let us take that ,
→ number of flags sold = f
→ number of pennant sold = p
Money earned by selling flags
→ Money = $6 * f = $6f
Money earned by selling pennants
→ Money = $1*p = $1p
Total money earned
→ Total Money = $6f + $1p
Total items sold
→ Total items = f + p = 50 . . . . . (i)
According to the question ,
→ 6f + p = 115 . . . . . (ii)
Solving equations (i) and (ii) ,
On subtracting them ,
→ 6f - f = 115 -50
→ 5f = 65
→ f = 65/5
→ f = 13
Substitute this in equation (i) ,
→ 13 + p = 50
→ p = 50 -13 = 37
Hence they sold 13 flags and 37 pennants .
