Answer: $45.00
Step-by-step explanation:
75 x 0.60 = 45
Answer:
$30
Step-by-step explanation:
First, change the percentage into decimal:
60% = 60/100 = 0.6
Multiply 75 with 0.6:
75 * 0.6 = 45
Note that this number 45 (0.6 of 75) is the amount off from the original price (75). Subtract 45 from 75
75 - 45 = 30
$30 is your answer

One store sells milk for $3.00 per gallon. A second store sells milk for $0.80 per quart. Formulas If you need two gallons, which store should you buy from?
Answer:
You should buy from the first store
Step-by-step explanation:
Since there are 4 quarts in a gallon, we will need to multiply .80 by 8 to figure out how much it costs for 2 gallons. This will be $6.40 for the second store, and in order to find out how many the first store offers, we multiply 3 by two, which is six.
So, the first store charges $6.00 for two gallons, and the second store does $6.40 for two gallons of milk
Answer:
The first store.
Step-by-step explanation:
This is easy, multiply 0.80 x 4 since there are four quarts in a gallon. You get 3.20. Then, multiply 3.20 by 2 to get 6.40 and 3.00 by 2 to get 6.00.
So
Store number one: $6.00
Store number two: $6.40

Final answer:
Joyce has read 9/10 of her book over the course of three days by adding together the fractions of the book she read each day and simplifying the result.
Explanation:
To determine the part of the book Joyce has read over the three days, we need to add the fractions representing the parts read each day. On Monday, Joyce reads 1/6 of her book, on Tuesday she reads 2/5, and on Wednesday she reads 1/3. Thus, we add these fractions together.
The Least Common Denominator (LCD) for 6, 5, and 3 is 30. We convert each fraction to have this common denominator:
1/6 = 5/302/5 = 12/301/3 = 10/30Now, we sum the fractions:
5/30 + 12/30 + 10/30 = (5 + 12 + 10)/30 = 27/30
27/30 can be simplified to 9/10 after dividing both numerator and denominator by 3. So, Joyce has read 9/10 of her book over the three days.
Find the height of the liquid in the glass pictured. Show all steps.
Answer:
6.32 cm.
Step-by-step explanation:
We can see that the given glass is in form of a cone.
To find the height of liquid in glass we will use formula:
[tex]h=\sqrt{l^2-r^2}[/tex], where,
h= Height of cone.
l= Slant height of cone.
r= Radius of cone.
We can see from our figure that diameter of cone is 6 cm, so radius of cone will be half of 6 cm, that is 3 cm.
We have been given slant height equals to 7 cm.
Let us substitute our values in above formula to find the height of liquid in the glass.
[tex]\text{Height of liquid in the glass}=\sqrt{7^2-3^2}[/tex]
[tex]\text{Height of liquid in the glass}=\sqrt{49-9}[/tex]
[tex]\text{Height of liquid in the glass}=\sqrt{40}[/tex]
[tex]\text{Height of liquid in the glass}=6.3245553203367587\approx 6.32[/tex]
Therefore, the height of liquid in the glass is 6.32 cm.

What is proportionality?the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Given, A 5-foot woman stands near a 4-foot cello case. The cello case casts a shadow that is 6 ft long.
Since the shadows are made because of the light of the Sun. thus we will assume the Angle of Light source will be the same.
So In angles are the same then
Base and perpendicular will be in proportion as per the Pythagorean theorem
So,
Women's height/cello's height = Women's shadow/cello's shadow
=> 5/4 = women's shadow/ 6
=> women's shadow = 7.5 ft
Therefore, the shadow of the woman will be 7.5 feet.

Answer:
18 feet
Step-by-step explanation:
Let the height be x
We are given that The side lengths of the state flag of Colorado are in the ratio 2:3.
Length: Height = 2:3
Length of the flag is 12 feet long
Length : Height = 12:x
So, ATQ
2:3::12:x
[tex]\frac{2}{3}=\frac{12}{x}[/tex]
[tex]x=\frac{12 \times 3}{2}[/tex]
[tex]x=18[/tex]
Hence it’s height is 18 feet
To find the height of the Colorado state flag, we can use the given ratio of side lengths and solve for the unknown height using a proportion.
Explanation:To find the height of the Colorado state flag, we can use the given ratio of side lengths – 2:3. Since the given length is 12 feet, we can set up the ratio equation as follows:
2/3 = 12/x
To solve for x, we can cross multiply:

The x distance is (3--3) = (3+3) 6
and the y distance is (5--5) = (5+5) = 10
We can use the Pythagorean theorem to calculate the hypotenuse, which is the distance from E to D
a^2 + b^2 = c^2
6^2 + 10^2 = c^2
36+ 100 = c^2
136 = c^2
Take the square root of each side
sqrt(136) = sqrt(c^2)
We only take the positive square root since the distance must be positive.
sqrt(4)sqrt(34) = c
2sqrt(34) = c
c is approximately 11.66 units
bring the fraction 12/y−x to a denominator of x−y
i would really appreciate it thx
Final answer:
To convert the fraction 12/(y-x) to have a denominator of (x-y), you multiply both numerator and denominator by -1, resulting in the fraction -12/(x-y).
Explanation:
To bring the fraction 12/(y−x) to a denominator of (x−y), realize that y−x is essentially -(x−y). This means we can multiply the numerator and denominator by -1 to get the desired denominator. The step-by-step process would be:
Begin with the original fraction: 12/(y−x).Recognize that y−x is the negative of (x−y). So, y−x = −(x−y).Multiply the numerator by -1 and the denominator by -1: (12 * -1)/((y−x) * -1).This simplifies to: -12/(x−y).Now, the fraction 12/(y−x) is expressed with the desired denominator (x−y) as -12/(x−y).

Step-by-step explanation:
-2|3 - 2r| < -34
|3 - 2r| > 17 (Note the inequality sign flips because we divide by negative)
Now we split it up into 2 inequalities :-
3 - 2r > 17
-2r > 14
r < -7 (answer)
and
3 - 2r < -17
-2r < -20
r > 10 (answer).
Answer:
r > 10 or r < - 7
Step-by-step explanation:
isolate the absolute value by dividing both sides by - 2
| 3 - 2r | > 17
Inequalities of the type | x | > a always have solutions of the form
x < -a OR x > a, hence
3-2r < - 17 or 3 - 2r > 17 ( subtract 3 from each interval )
- 2r < - 20 or - 2r > 14 ( divide both intervals by - 2 )
Remembering to reverse each inequality symbol as a result of dividing by a negative quantity.

On Sunday, a local hamburger shop sold a combined total of 378 hamburgers and cheeseburgers. The number of cheeseburgers was sold 2 times the number of hamburgers. How many hamburgers were sold?
Answer:
The number of hamburgers sold was 126.
Step-by-step explanation:
Let h = number of hamburgers sold
let c = cheeseburgers sold
c+h = 378
c = 2h
Substitute c =2h into c+h =278
c+h =378
2h+h = 378
Combine like terms
3h = 378
Divide by 3
3h/3 =378/3
h =126
The number of hamburgers sold was 126.
Final answer:
To determine how many hamburgers were sold, we set up a system of equations and found that 126 hamburgers were sold.
Explanation:
The local hamburger shop sold a combined total of 378 hamburgers and cheeseburgers. We are told that the number of cheeseburgers sold was 2 times the number of hamburgers. We can set up a system of equations to solve this problem using h to represent the number of hamburgers and c to represent the number of cheeseburgers:
h + c = 378 (the total number of burgers sold)
c = 2h (the number of cheeseburgers was 2 times the number of hamburgers)
Now let's substitute the second equation into the first to solve for h:
h + 2h = 378
3h = 378
h = 378 ÷ 3
h = 126
Therefore, the number of hamburgers sold was 126.
Solve for u. I need a little help.
Answer:
value of 'u'= -54
Step-by-step explanation:
[tex]30 = -\frac{5}{9}u[/tex]
To eliminate any number , we always do opposite operation
To remove denominator 9, we multiply both sides by 9
[tex]30*9 = -\frac{5}{9}*9*u[/tex]
270 = -5u
To remove -5 we divide by -5 on both sides
[tex]\frac{270}{-5} = \frac{-5u}{-5}[/tex]
-54= u
So value of u= -54

Evaluate the expression x+4/3x when x=2
Final answer:
To evaluate the expression x + 4 / 3x for x=2, substitute 2 into the expression and solve. For the plus sign, the result is 1, and for the minus sign, the result is -1/3.
Explanation:
To evaluate the expression x + 4 / 3x with x=2, we perform the following steps:
First, we plug in the value of x into the expression,
For the plus sign in the numerator: (2 + 4) / (3 × 2) = 6 / 6 = 1For the minus sign in the numerator: (2 - 4) / (3 × 2) = -2 / 6 = -1/3Therefore, when evaluating for both signs in the numerator, we get x = 1 for the plus sign and x = -1/3 for the minus sign.
At Friday's football game, 1,294 tickets were sold for a total amount of $8,816.00. If each student ticket costs $5.00, and each adult ticket costs $8.00, how many student tickets were purchased?
Answer:
512 student tickets.
Step-by-step explanation:
Let x be number of student tickets and y be number of adult tickets.
We have been given that at Friday's football game 1,294 tickets were sold. We can represent this information as:
[tex]x+y=1294...(1)[/tex]
We are also told that each student ticket costs $5.00, and each adult ticket costs $8.00 and 1,294 tickets were sold for a total amount of $8,816. We can represent this information as:
[tex]5x+8y=8,816...(2)[/tex]
From equation (1) we will get,
[tex]y=1294-x[/tex]
Substituting this value in equation (2) we will get,
[tex]5x+8(1294-x)=8,816[/tex]
[tex]5x+10352-8x=8,816[/tex]
[tex]-3x+10352=8,816[/tex]
[tex]-3x=8,816-10352[/tex]
[tex]-3x=-1536[/tex]
[tex]x=\frac{-1536}{-3}[/tex]
[tex]x=512[/tex]
Therefore, 512 student tickets were purchased at Fridays football game.
