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.

A 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.
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°

I WILL GIVE BRAINLIEST!!!! ASAP!!! A reflection over the x-axis maps △ABC to △A′B′C′. Do the preimage and image have the same size and shape? Explain.
Yes, The preimage and the image have the same shape and size.
What is Reflection of an Object?The reflection of an object across an axis is creating an image that has the same shape and size.
A triangle ABC is reflected over the x-axis to form A'B'C'
When reflected over an axis, the coordinate of the other axis is changed to its additive inverse.
(x,y)-------> (x,-y)
Let the coordinate of the triangle is (1,1),(3,5),(3,1)
The image of the triangle when reflected over x-axis is
(1,1),(3,5),(3,1) -------------> (1,-1),(3,-5),(3,-1)
The shape of a right-angled triangle is the same in the image, the length of the side is same, it is just an image of the same shape and size.

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

Toni rides the Ferris wheel shown for 15 revolutions. A photo of a Ferris wheel has the diameter labeled fifty-six feet. Question 1 Part A How far does Toni travel in one revolution? Use 227 for π
Answer:
a. 176 feet b. 2640 feet
Step-by-step explanation:
a. Since the diameter of the Ferris wheel is D = 56 feet, the distance Toni travels in one revolution is the circumference of the Ferris wheel, C = πD.
So C = 22/7 × 56 ft = 22 × 8 ft = 176 feet
b. The distance traveled in 15 revolutions is thus D' = 15 × distance of one revolution = 15 × 176 = 2640 feet

A band is playing at an auditorium with floor seats and balcony seats. The band wants to sell the floor tickets for $15 each and balcony tickets for $12 each. They want to make at least $3,000 in ticket sales.
Below is a sketch of the graph.
a) Write the inequality of the line.
b) Identify the ordered pair for point A.
c) Identify the ordered pair for point B.
d) State which direction they should shade and why that makes sense in context.
Answer:
Step-by-step explanation:
Lets denote number of floor tickets by x and
Lets denote number of balcony tickets by y as shown in the figure in the question
so, floor tickets are sold for $15 each which means number of x tickets would be sold by $15 multiplied by x which means 15x and balcony tickets are sold for $12 each which means number of y tickets would be sold by $12 multiplied by y which means 12y furthermore it says they want to make at least $3000 which would mean they want to make at least $3000 or higher meaning ≥3000 so the inequality would be
a) [tex]15x+12y\geq 3000[/tex]
b) The ordered pair A we can see that A is the y-intercept which means the point A can also be written as (0 , y) so we put this point into our equation
15x + 12y = 3000 which is the boundary line. So here goes,
[tex]15x+12y=3000\\15(0)+12(y)=3000\\12y=3000\\y=3000/12\\y=250\\[/tex]
so our y-intercept is 250 which means Point A is (0 , 250)
c) They should shade the area above the boundary line because in this context the band that is playing wants to make at least $3000 which means they want to make more than $3000 . So when a ≥ sign appear we shade the area above the boundary line and when the ≤ sign appears we shade the area below the boundary line. If it were in the question the bands wants to make at most $3000 then the ≤ would appear.
I have attached a graph to clearly visualize the solution as well.
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.

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
