During a store's closing sale, everything is 65% off. Victors goes into the store to buy a shirt and a pair of pants, and spends 15.40 before tax.How much would he have spent without the sale
Answer:
$51.33
Step-by-step explanation:
Everything is off 65% so that means that $15.40 if 35% of the original price(100%-65%)
Set up Equation:
[tex]\frac{15.40}{x} = \frac{30}{100}[/tex]
Simplify:
[tex]\frac{15.40}{x} =\frac{3}{10}[/tex]
Multiply the first numerator by the last denominator and the first denominator by the last numerator
[tex]3x=154[/tex]
Divide 3 by both sides:
x= 51.33

The drama club was selling tickets to the school play. Adult tickets cost $8.00 each, and student tickets cost $5.00 each. The little theater holds 142 people and was sold out for both Friday and Saturday. The total sales for the two days were $1,940. How many people got tickets for both Friday and Saturday combined
Answer:
108 student tickets, and 176 adult tickets were sold
Step-by-step explanation:
Adult ticket $8 Call the number of adult tickets sold "a"
Student ticket $5 Call the number of student tickets sold "s"
Since we are talking about TWO consecutive days of sold out seats, the total number of seats sold were 2* 142 = 284
Then we create two different equations with the information given:
a + s = 284
8 * a + 5 * s = 1948
we can solve for s in the first equation as follows: s = 284 - a
and use it in the second equation
8 a + 5 (284 - a) = 1948
8 a + 1420 - 5 a = 1948
combining
3 a = 528
a = 528/3
a = 176
we find the number of student tickets using this answer in the substitution equation we used:
s - 284 - 176 = 108
Therefore 108 student tickets, and 176 adult tickets were sold.

When 4 times the number x is added to 13, the result is 8. what number results when 2 times x is added to 7
Answer:
.
Step-by-step explanation:
.
Answer:
[tex]4 \frac{1}{2} [/tex]
Step-by-step explanation:
Let's find the value of x first.
From the first sentence:
4x +13= 8
Subtract 13 from both sides:
4x= 8 -13
4x= -5
[tex]x = - \frac{5}{4} [/tex]
[tex]x = - 1 \frac{1}{4} [/tex]
2 times x is added to 7 → 2x +7
2x +7
[tex]= 2( - \frac{5}{4} ) + 7 [/tex]
[tex] = - \frac{5}{2} + 7[/tex]
[tex] = 4 \frac{1}{2} [/tex]
Mrs. Piazza's class is voting on where to take a field trip. 1/4 of the students want to go to the zoo and 1/8 of the students want to go to the aquarium. The rest of the students want to go to a baseball game. What fraction of the class wants to go to a baseball game?
Answer:
5/8
Step-by-step explanation:
The fraction of students that went to the baseball game can be known by adding the fraction of students that went to the zoo and the aquarium and subtracting it from 1
Sum of the fraction of students that went to the zoo and the aquarium
= [tex]\frac{1}{4} + \frac{1}{8}[/tex]
[tex]\frac{2 + 1 }{8}[/tex]
= [tex]\frac{3}{8}[/tex]
Fraction of students that went to the baseball game = 1 - [tex]\frac{3}{8}[/tex]
[tex]\frac{8}{8} - \frac{3}{8}[/tex] = [tex]\frac{5}{8}[/tex]
A circle centered at (–1, 2) has a diameter of 10 units. Amit wants to determine whether (2, –2) is also on the circle. His work is shown below.
The radius is 5 units.
Find the distance from the center to (2, –2).
StartRoot (negative 1 minus 2) squared + (2 minus (negative 2)) squared EndRoot. StartRoot (negative 3) squared + (0) squared EndRoot = 3.
The point (2, –2) doesn’t lie on the circle because the calculated distance should be the same as the radius.
Is Amit’s work correct?
No, he should have used the origin as the center of the circle.
No, the radius is 10 units, not 5 units.
No, he did not calculate the distance correctly.
Yes, the distance from the center to (2, –2) is not the same as the radius.
Answer:
3rd
C
Explanation:
Amit's mistake : The point (2, –2) doesn’t lie on the circle because the calculated distance should be the same as the radius.
The point (2,-2) is on the circle, and Amit's claim is wrong
How to determine if Amit's work is correct?The given parameters are:
Center = (-1,2)
Diameter = 10 units
Point = (2,-2)
Start by calculating the radius, r
r = diameter/2
r = 10/2
r = 5
Next, calculate the distance from the point to the center using:
[tex]r = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
This gives
[tex]r = \sqrt{(2 + 1)^2 + (-2-2)^2}[/tex]
Evaluate
r = 5
The distance from the center to the point equals the radius of the circle
Hence, the point is on the circle, and Amit's claim is wrong

A motorcyclist leaves City A and rides at a constant speed towards City B, which is 225 km away. After 1.5 hours, the motorcyclist stops a half an hour lunch. To reach City B on time, the motorcyclist increases his speed after lunch by 10km/hour. Find the motorcyclists original speed
Answer:
50 km/hr
Step-by-step explanation:
OK, this is how I solved this problem.
Let r = original rate of speed
t = time after the stop to finish the trip
Time for trip without stopping is 225/r
(1) 1.5 + .5 + t = 225/r This is a time equation
(2) 1.5r + t(r + 10) = 225 This is a distance equation
(1) 2 + t = 225/r (2) 1.5r + tr + 10t = 225
2r + tr = 225
tr = 225 - 2r 1.5r + 225 - 2r + 10(225/r - 2) = 225
t = 225/r - 2
-.5r + 225 + 2250/r - 20 = 225
-5r + 2250 + 22500/r - 200 = 2250
-5r^2 + 2250r + 22500 - 200r = 2250r
5r^2 + 200r - 22500 = 0
5(r^ + 40r - 4500) = 0
5(r - 50)(r + 90) = 0
r = 50 or r = -90
The rate cannot be negative, so the original speed 50 km/hr

Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction.
Answer:
We have 31/36 gallons of paint left after painting the mural.
Step-by-step explanation:
"Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction."
==================================================================
First change each number into a improper fraction:
1 1/8 = 9/8
1 1/9 = 10/9
7/8 = 7/8
=================================================================
"If Mark has 9/8 gallons of yellow paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to make the denominators same.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 9/8.
9/8 - 6/8 = 3/8
We will have 3/8 gallons of yellow paint.
==================================================================
"If Mark uses 10/9 gallons of green paint, and he uses 3/4 gallons"
- We have to multiply 10/9 by 4/4, and 3/4 by 9/9, to get a common denominator.
10/9 × 4/4 = 40/36
3/4 × 9/9 = 27/36
Now subtract 27/36 from 40/36
40/36 - 27/36 = 13/36
We will have 13/36 gallons of green paint.
==================================================================
"If Mark uses 7/8 gallons of blue paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to get a common denominator.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 7/8.
7/8 - 6/8 = 1/8
We will have 1/8 gallons of yellow paint.
==================================================================
Now, we will add the leftover amounts of paint to find the answer.
3/8 + 13/36 + 1/8
Add "like terms".
4/8 + 13/36
Simplify 4/8 into 1/2
1/2 + 13/ 36
Multiply 1/2 by 18/18 to get a common denominator.
1/2 × 18/18 = 18/36
Substitute 18/36 as 1/2 in the expression.
18/36 + 13/36 = 31/36
So, We have 31/36 gallons of paint left after painting the mural.
==================================================================
Hope I helped, Have a nice day!
