Answer:
Vanilla = 10 sundaes
Step-by-step explanation:
Total sundaes = 25
1/5 of the sundaes are mint ice cream
Mint ice cream = 1/5 of 25
= 1/5 * 25
= 25/5
= 5
Sundaes remaining = total sundaes - sundaes for mint ice cream
= 25 - 5
= 20 sundaes
Sundaes remaining = 20 sundaes
1/2 of the remaining sundaes are chocolate
= 1/2 of 20
= 1/2 * 20
= 20/2
= 10
Chocolate ice cream = 10
The rest will be vanilla
Sundaes remaining = 20 - 10
= 10 sundaes
Vanilla = 10 sundaes
Prove that the points A (-3,-1), B(6,5) and C (3,3) are collineas
Answer:
nose porque está en una idioma que no se
Answer:
see explanation
Step-by-step explanation:
To show the points are collinear, that is lie on the same line.
Then the slope between A and B, B and C must be equal
Calculate slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(- 3, - 1) and (x₂, y₂ ) = B(6, 5)
[tex]m_{AB}[/tex] = [tex]\frac{5+1}{6+3}[/tex] = [tex]\frac{6}{9}[/tex] = [tex]\frac{2}{3}[/tex]
Repeat with (x₁, y₁ ) = B(6, 5) and (x₂, y₂ ) = C(3, 3)
[tex]m_{BC}[/tex] = [tex]\frac{3-5}{3-6}[/tex] = [tex]\frac{-2}{-3}[/tex] = [tex]\frac{2}{3}[/tex]
Since the slope between the 2 segments are equal and there is a common point B.
Then the points A, B and C are collinear
The measures of the angles of a triangle are shown in the figure below. Solve for x.
хо
870
570
Answer:
Step-by-step explanation:
we know that the sum of the angles in a triangle=180
87+57+x=180
144+x=180
x=180-144=36
x=36

Step-by-step explanation:
what's the domain and range of y=-2x^2+5x-7
Answer:
Domain: All real numbers Range: (-∞, -31/8]
Step-by-step explanation:
Since the parent function for this equasion is y=x^2, you know that the graph wil be parabolic in shape. All parabolic functions have a domain of all real numbers. Now when you rewrite the graph in vertex form, you will see that the top vertex is at y=-31/8, this is going to restrict the range to be (-∞, -31/8]. I have provided a graph using the app PhotoMath.

How do I do one of these types of problems?
Answer:
x = 5
Step-by-step explanation:
I'm assuming the question is asking to solve for variable x.
The two red arrows signify the two lines are congruent, meaning they equal the same measurement.
In other words:
23x - 5 = 21x + 5
Isolate the variable x
Add 5 to both sides to cancel 5 from the left side
23x - 5 + 5 = 21x + 5 + 5
23x + 0 = 21x + 10
23x = 21x + 10
Subtract 21x from both sides to cancel 21x from the right side
23x - 21x = 21x - 21x + 10
2x = 0x + 10
2x = 10
Divide both sides by 2 to isolate the variable x
2x ÷ 2 = 10 ÷ 2
x = 5
When solving for these types of problems, always isolate the variable. Also, keep in mind that whatever you do to one side, you must do to the other (such as how I added 5 to both sides).
Riya looks at the temperature in the kitchen. What is the temperature in the kitchen to the nearest division
Answer:
24 degree Celsius
Step-by-step explanation:
Temperature may be defined as the intensity or the degree of heat that is present in any substance or present in the environment. It is the measure of hotness or coldness of any item or surroundings. Temperature is measured with the help of a comparative scale which shows the how hot or cold the place is or item is.
In the context, Riya uses a comparative scale like the thermometer to measure the temperature of the kitchen. The mercury level on the scale rises and stops at a point indicating the temperature of the kitchen.
Thus the temperature of the kitchen according to the scale is [tex]$24 ^ \circ C$[/tex].
If there was a point M(3,6) and it was dilated to M'(1, 2), what kind of scale
factor was used for the dilation? What is the scale factor? *
A bakery sells vanilla cupcakes and mocha cupcakes. It sold 300 cupcakes in a day, and 29% of them were mocha. How many of the cupcakes sold that day were vanilla? Answer:
Answer:
213
Step-by-step explanation:
Given data
Total cupcakes sold= 300
we are told that 29% are mocha
Required
The amount of cupcakes that is vanilla
Let us find the amount that is mocha
=29/100*300
= 0.29*300
= 87 mocha
Hence the amount that is vanilla is
=300-87
=213
Answer:
213 Cupcakes

An item is regularly priced at $40 it is on sale for 60% off the regular price how much in dollars is discounted from the regular price
Answer:
$24 and $16
Step-by-step explanation:
well let’s go through this step by step.
we have $40 which is the regular price, but not only do you want to find what 60% of 40 is, but you want to find out how big the difference is between the 2, in dollars. But i believe we can do that.
So let’s just think. Do you know how to get a percent of something? If so, ignore this next part. If not, all you want to do is take 40 x 0.60. or whatever number you need. if it’s out of 100, that’s what you would do.
So now that we know how to get a percent of something, let’s find 60% of 40.
40 x 0.60 gives us 24, or in this case it’d be $24.
Great! we found the discount! now all we need to do is find out the difference.
All we need to do from here is take 40 - 24. what is 40 - 24?
16!
Now you’re done! the discount brings it down to $24 and the difference between the starting price and the discount price is 16 dollars.
i hope this was able to help you!

Part A) The Rosegold Cinema is conducting a mathematical study. In its theater, there are 225 seats. Adult tickets cost $10.50 and child tickets cost $6.25. The cinema's goal is to sell at least $1250 worth of tickets for the theater. Write a system of linear inequalities that can be used to find the possible combinations of adult tickets, x, and child tickets, y, that would satisfy the cinema's goal.
Part B) Marta claims that selling 100 adult tickets and 60 child tickets will result in meeting the cinema's goal. Explain whether she is correct or incorrect, based on the graph drawn.

Answer:
391.5
Step-by-step explanation:
Find the area of all the sides.
Triangles area: 9 X 10=90 because there are 2 so you don't need to divide by 2
Rectangles area: (9X10)X2= 180 because there is 2
Another rectangle area 13.5 X 9= 121.5
Add all: 90+180+121.5

Explain how the Distributive Property can be used to solve the equation.
3(x + 4) = 36.
Answer:
x = 8
Step-by-step explanation:
3 ( x + 4 ) = 36
divide both sides by 3
x + 4 = [tex]\frac{36}{3} }[/tex]
divide 36 by 3 to get 12
x + 4 =12
subtract 4 from both sides
x = 12 - 4
subtract 4 from 12 to get 8
x = 8
11x + x = 60
full answer pls
Answer:
x=5
Step-by-step explanation:
First combine the like terms:
11x+x = 12x
then you'll get 12x=60
divide by 12 to get x by itself
whatever you do on one side you have to do on the other so :
12x/12=60/12
x=5
your answer is 5
Answer:
11x + x =12x thus
12x/12 =60/12
x=5
value of x is 5

An amusement park sold 810 discount tickets and 90 full-price tickets. What percentage of the tickets sold were discount tickets? HELP ME ASAP PLEASEEEEE
Answer:
90%
Step-by-step explanation:
First, find the total number of tickets sold.
810 discount + 90 full-price = 900 tickets
Now you need to find what percent 810 is of 900.
% of 900 = 810
810/900 = 0.9
Convert this to a percentage.
0.9 × 100% = 90%
90% of tickets were sold at a discount.
