Answer:
p = $150
Step-by-step explanation:
Let p represent the original price. Then 10% of that is the discount: 0.10p.
The price after discount is 90% of the original price, or (1.00-0.10)p = 0.90p = $135. We next solve this equation for p: 0.90p = $135, or p = $150.
Vita used the model below to find the sum of two mixed numbers what is the sum?
Answer:
the first mixed number is 1 8/10 which is reduced to 1 and 4/5 and the seconde is 2 and 3/5 added equals 4 and 2/5
Step-by-step explanation:
1 plus 2 equals 3
and 3/5 plus 4/5 equals 7/5
turn it into a mixed number which equals 1 and 2/5 the add 3 and u get 4 and 2/5
Does the relation in the table represent direct variation, inverse variation, or neither? If it is director
inverse variation, write an equation to represent the relation. Explain your answer.
9514 1404 393
Answer:
inverse
y = 10/x
Step-by-step explanation:
Inverse variation is described by an equation of the form ...
y = k/x
The value of k is a constant equal to ...
k = xy = 5·2 = 10·1 = 15·2/3 = 20·1/2 = 10
__
Here, the products of the x- and y-values are all 10, so the inverse variation equation is ...
y = 10/x

15,2
Answer:
A=11,13,17,19 B=12,18 None=10,14,16,19 Both=15
Step-by-step explanation:
11,13,15,17,19 are all odd so they go in A
12,15,18 Are all multiples of 3 so they go in B
10,14,16,19 Are not classified so they go outside of the diagram but inside E
15 is odd and a multiple of 3 so put it in the center and not with A and B

Which expressions are equivalent?
1. 3x-7y and -7y+3x
2. 3x-7y and 7y-3x
3. 3x-7y and 3y-7x
4. 3x-7y and-3y+7x
Answer:
1. 3x-7y and -7y+3x
Step-by-step explanation:
1. 3x -7y and -7y +3x
This is correct because the terms remain unchanged. The -7y stays a -7y and the positive 3x stays a positive 3x.
2. 3x -7y and 7y -3x
This is not correct because the signs of the 3x and 7y switch. For the expressions to be equivalent, the signs must remain unchanged.
3. 3x -7y and 3y -7x
This is not correct because the variables of the 3 and 7 switched. The variables need to stay the same, for the expressions to be equivalent.
4. 3x-7 and -3y+7x
This is not correct because both the variables and the signs of the expressions changed. Both the signs and variables would need to stay the same in order to be equivalent.

what is the scale factor of the small triangle to the large triangle?
Answer:
I'm pretty sure it's 4.3?
Step-by-step explanation:
Because you divide the larger triangles side first because you are figuring out the scale factor of the small triangle to the larger triangle, not the other way around.
Sorry if i'm wrong
Answer:
first, find the area of the small triangle: 3 times 3 equals 9 divided by 2 equals 4.5.
second, find the area of the big triangle: 13 times 13 equals 169 divided by 2 equals 84.5.
Find difference: 84.5 minus 4.5 equals 80

Step-by-step explanation:
A retail ice cream salesman divides his working days into 'sunny', 'medium', and 'cold'. He estimates that the probability of it being sunny is 0.2, and cold 0.3. If his gross sales on these three types of day are $50, $35, and $10 respectively on average and his average daily costs are $18 on any day.
Required:
a. Complete the probability distribution.
b. Find his expected profit per day.
Answer:
30.5
Step-by-step explanation:
Let ;
Sunny = S ; Medium = M ; Cold = C
_____ S _____ M ___ C
__X : 50 ____ 35 ___ 10
P(X) : 0.2 ____ 0.5 __ 0.3
P(M) = 1 - (0.2 + 0.3)
P(M) = 1 - 0.5 = 0.5
Expected profit per day, E(X)
E(X) = sum of (X * p(x)
E(X) = (50 * 0.2) + (35 * 0.5) + (10 * 0.3)
E(X) = 10 + 17.5 + 3
E(X) = 30.5
The area of a triangle varies jointly with the height of the triangle and the length of its base. The area of one triangle is 200 square centimeters when its height
is 25 centimeters and its base length is 16 centimeters. What is the area of a triangle having a height of 20 centimeters and a base length of 15 centimeters?
0600 square centimeters
O 300 square centimeters
O 150 square centimeters
160 square centimeters
Answer:
150 square centimeters
Step-by-step explanation:
Area of a triangle:
The area of a triangle is the multiplication of 0.5, the base length and the height length.
What is the area of a triangle having a height of 20 centimeters and a base length of 15 centimeters?
[tex]A = 0.5*20*15 = 10*15 = 150[/tex]
The area of the triangle is 150 square centimeters.
9. Find the value of
the expression.
16 + 4 + (42 - 3) =
Answer:
59Step-by-step explanation:
16 + 4 + (42 - 3) = 20 + 39 =59Answer:
59
Step-by-step explanation:
16 + 4 + (42-3) = 59. Do parentheses first. (42-3) = 39. Which changes the equation to 16 + 4 + (39). 39 + 4 = 43. Then the equation changes to 16 + 43. These added together equal 59. Hope this helps!

Can someone help please please
Answer: A: (6, 5)
Step-by-step explanation:
When graphing a system of equations, you can find the solution by finding where the graphs intersect. In this case, the graphs intersect at (6, 5).
To verify that this is indeed a solution to the system of equations, we can substitute (6, 5) into both of the given equations:
[tex]y = \frac{1}{2}x + 2[/tex]
[tex]5 = \frac{1}{2} * 6 + 2[/tex]
[tex]5 = 3 + 2[/tex]
[tex]5 = 5[/tex]
[tex]y = x - 1[/tex]
[tex]5 = 6 - 1[/tex]
[tex]5 = 5[/tex]
Since both equations hold true when plugging in the given coordinate (6, 5), we know that this is a solution to the system of equations.
need help geometry question central angles and arcs plsss
someone help with math:
For which equation is b = 5 not the solution?
options:
1. 8 - b = 13
2. b + 6 = 11
3. b + 4 = 9
4. 12 - b = 7
Answer:
option 2 and 3
b+6=11
b+4=9
Answer:
1. 8 - b = 13
Step-by-step explanation:
It says for which equation is b = 5 not the solution.
So, we need to plug in 5 into every b, and find out which one is incorrect.
1. 8 - 5 = 13 (incorrect)
2. 5 + 6 (correct)
3. 5 + 4 = 9 (correct)
4. 12 - 5 = 7 (correct)
Therefore, option 1 is the answer to your question.

Triangle PQR is shown. The triangle has a base of 4 in and a height a 2.5 in.
Which measurement is closest to the area of triangle PQR in square inches?
5 in2.
8 3/4in.2
6 1/2in.2
11in.2
Answer:
A
Step-by-step explanation:
Area = 1/2 * b * h
b = 4 in
h = 2.5 inches
Area = 1/2 * 4 * 2.5
Area = 2 * 2.5
Area = 5 in^2
