please give thanks by hitting heart button! :)
Answer:
15%
Step-by-step explanation:
1. Subtract the sale price from the normal price.
$1000 - $850 = $150.
2. Divide this amount by the original price.
$150/$1000 = 0.15
3. Multiply by 100 to get the %.
0.15 x 100 = 15%

Step-by-step explanation:
Cookies are on sale! Today each cookie costs \$0.75$0.75dollar sign, 0, point, 75 less than the normal price. Right now if you buy 777 of them it will only cost you \$2.80$2.80dollar sign, 2, point, 80!Write an equation to determine the normal price of each cookie
Answer:
The equation to determine the normal price of each cookie is
7(x - 0.75) = 2.80
The normal price of each cookie = $1.15
Step-by-step explanation:
Let us represent the normal price of a cookie as : x
We are told that:
Today each cookie costs \$0.75less than the normal price.
The price of a cookie today is
x - 0.75
Right now if you buy 7 of them it will only cost you \$2.80$
Hence:
7(x - 0.75) = 2.80
Solving for x
7x - 5.25 = 2.80
7x = 2.80 + 5.25
7x = 8.05
x = 8.05/7
x = $1.15
The normal price of each cookie = $1.15
Answer:
$ 1.15
Step-by-step explanation:
7(c-0.75) = 2.80 is the equation
$1.15 is the total for C

what is the value of f
Answer:
f = 54°
Step-by-step explanation:
54° and f are vertical angles and are congruent, thus
f = 54°
Find the measure of each acute angle.
(19x − 1)∘ = and (13x − 5)∘ =
Answer:
34 degrees; 56 degrees
The measures of each of the acute angles are 56 degrees and 34 degrees.
Step-by-step explanation:
The measures of a triangle add up to 180 degrees.
One angle has the measure of 90 degrees since it is marked as a right angle.
Using this info we can create an equation to solve for x.
(19x-1)+(13x-5)+90=180
Now solve for x.
32x-6+90=180
32x=96
x=3
Now to find the measure of each angle subsitute the value of x.
(19x-1)=19*3-1=56 degrees
(13x-5)=13*3-5=34 degrees
The measures of each of the acute angles are 56 degrees and 34 degrees.
Answer:
19x - 1 ➡ 19 × 3 - 1 = 56°
13x - 5 ➡ 13 × 3 - 5 = 34°
Step-by-step explanation:
The given triangle is a right triangle which means one of the angle has a measurement of 90° and since the sum of interior angles in a triangle is equal to 180° the sum of other two angles must be 90°
19x - 1 + 13x - 5 = 90 add like terms
32x - 6 = 90 add 6 to both sides
32x = 96 divide both sides by 32
x = 3
19x - 1 ➡ 19 × 3 - 1 = 56°
13x - 5 ➡ 13 × 3 - 5 = 34°

A TV salesman will make 18% commission on the profit of every TV he sells. If the electronics store buys a TV for $600 and the salesman sells the TV for $899, how much is his commission?
Answer:
Commission= $53.82
Step-by-step explanation:
First, we need to calculate the gross profit of the sale:
Gross profit= sale price - total cost
Gross profit= 899 - 600
Gross profit= $299
Now, the commission made by the seller:
Commission= gross profit*commission rate
Commission= 299*0.28
Commission= $53.82

I can't understand this one bit
Answer:
It would be $1,590.75 more if it were compounded quarterly than monthly.
Step-by-step explanation:
In order to solve this problem, you need to understand the Compound Interest Formula.
[tex]A= P(1 + \frac{r}{n})^t[/tex]
Where A is the Amount, P is the principal or the initial amount received, r is the rate, n is the number of times (per year) it is compounded, and t is the time in years.
The question gives you all of the information to input into the formula. You have the principal, $5000, the rate, 6% (.06), it's being compounded monthly (12 & 4 per year), and we have the years, 25.
We need to compare the two formulas where the only thing that will change is n. n will be 12 (compounded monthly) and 4 (compounded quarterly).
Compounded monthly
[tex]A=5000(1+\frac{0.06}{12})^{25}\\A = 5663.98[/tex]
Compounded monthly, the account would have $5,663.98 or $5,664 (simplified).
Compounded quarterly
[tex]A=5000(1+\frac{0.06}{4})^{25}\\A =7254.73[/tex]
Compounded quarterly, the account would have $7,254.73 or $7,255 (simplified).
Now, we need to find the difference between monthly and quarterly.
7254.73 - 5663.98 = $1,590.75
It would be $1,590.75 more if it were compounded quarterly than monthly.

Ahmad’s father is 4 times as old as Ahmad. After 5 years, father will be three times as old as Ahmad. Find their present ages
The present age of Ahmed and Ahmed's father is 12 and 36 respectively.
Step-by-step explanation:
Given : Ahmed's father is thrice as old as Ahmed. After 12 years, his age will be twice that of his son.
To Find : Their present age ?
Solution :
Let the Ahmed's age be 'x'.
Ahmed's father is thrice as old as Ahmed.
i.e. Ahmed's father age is '3x'
After 12 years, his age will be twice that of his son.
i.e. 3x+12 = 2(x+12)3x+12=2(x+12)
Solving the equation,
3x+12 = 2x+243x+12=2x+24
x=12x=12
So, Ahmed's age is 12.
Ahmed's father age is 3\times 12=363×12=36
Therefore, The present age of Ahmed and Ahmed's father is 12 and 36 respectively.
There is 3 times in space of 4 times please mark as brainlistA candle burned at a steady rate. After 33 minutes, the candle was 11.2 inches tall. Eighteen minutes later, it was 10.75 inches tall. Use an equation in point-slope form to determine the height of the candle after 2 hours. Round the answer to the tenth place if necessary
Answer:
9.025 inches
Step-by-step explanation:
Let the length be represented by:
[tex]L = mt+L_0[/tex]
Where [tex]L[/tex] is the length of candle at time [tex]t[/tex]
[tex]m[/tex] is the rate at which the candle is burning.
And [tex]L_0[/tex] is the initial length of the candle.
As per the question statement, let us put the given values in the equation.
[tex]11.2 = m\times 33 + L_0 .... (1)\\10.75 = m\times 51+L_0 ..... (2)[/tex]
Subtracting (1) from (2):
[tex]0.45 = -18m\\\Rightarrow m = -0.025[/tex]
Putting the value of [tex]m[/tex] in the equation (1):
[tex]11.2 = -0.025 \times 33+L_0\\\Rightarrow L_0 = 12.025[/tex]
Therefore, the equation becomes:
[tex]L = -0.025t + 12.025[/tex]
Now, we have to find the height of candle after 2 hours.
2 hours mean 120 minutes.
[tex]L = -0.025 \times 120 + 12.025\\\Rightarrow L = 9.025\ inches[/tex]
Therefore, the height of candle is 9.025 inches.

The radio station in North Pole, AK plays Christmas songs all day and night from Thanksgiving through Christmas. They play 12 per hour for 15 hours a day, and 8 songs per hour for the rest of the day. They like to have a mix of traditional and modern songs with a relationship of 9 traditional songs to every 5 modern songs. How many traditional songs and how many modern songs will they play in one day?
Answer:
Traditional = 162
Modern = 90
Step-by-step explanation:
Given that:
12 songs per hour for 15 hours
8 songs per hour for the rest of the day ; (24 - 15) = 9 hours ;
That is ; 8 songs per hour for 9 hours
Total number of songs played per day :
(12 * 15) + (8 * 9) = 252 songs
If songs are mixed using the ratio 9:5 (traditional : modern)
Traditional songs :
(9 * 252) / (9 + 5) = 162
Modern songs :
(5 * 252) / (9 + 5) = 90

Brandon decided to make his own hand sanitizer.
To be effective, hand sanitizer should contain 60% alcohol.
How much water does Brandon need to make 250ml of hand sanitizer?
I WILL REWARD BRAINLIEST FOR CORRECT ANSWER
Answer:
I think he might need 100ml.
Step-by-step explanation:
Brandon needs to use 100 ml of water to make 250 ml of hand sanitizer.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
To save money, Brandon made his own hand sanitizer. Hand sanitizer needs 60% alcohol to be effective.
We have to determine the amount of water to manufacture 250ml of hand sanitizer.
To make 250ml of hand sanitizer with 60% alcohol, Brandon needs to use 250ml x 60% = 150ml of alcohol.
Since the total volume of the hand sanitizer is 250ml,
Brandon needs to use 250ml - 150ml = 100ml of water to make 250ml of hand sanitizer.
Therefore, he needs to use 100 ml of water to make 250 ml of hand sanitizer.

If the price is the same for each yard, how much money would 12 yards of fabric cost? $18.00 $21.00 $24.75 $26.25
Answer:
The answer is $21
Step-by-step explanation:
The amount of money for 12 yards of fabric is $ 21.00
Given data:
To determine the cost of 12 yards of fabric, we can use the information provided in the table. We observe that the cost of fabric increases linearly with the number of yards.
The table shows that 3 yards of fabric cost $5.25. To find the cost per yard, we divide the total cost by the number of yards:
$5.25 / 3 = $1.75
On simplifying the equation:
Now we can use this cost per yard to calculate the cost of 12 yards:
$1.75 × 12 = $21.00
Hence, 12 yards of fabric would cost $21.00.
