Answer: 13 minutes
Step-by-step explanation: common sence every minute the heart beats 25 times so 25 times 3 equals 75 so if that s true then 25 times 13 equals 325 ;)
Answer:
12.99 - 13 min.Step-by-step explanation:
It is 12.99 - 13 min. because 325 divided by 75
equals 4.33 and so on. If you times 4.33 by 3
you get 12.99, if your teacher said to round it
then do 13 Min. Hope this helps! <3

Together, Linda and Penny sold 492 boxes of Girl Scout cookies. Penny
sold 48 more boxes than Linda. How many boxes did Linda sell?
Answer:
222
Step-by-step explanation:
Let L = number of boxes Linda sold.
Let P = number of boxes Penny sold.
The sold a total of 492 boxes.
L + P = 492
Penny sold 48 more boxes than Linda.
P = L + 48
Substitute P with L + 48 in the first equation and solve for L.
L + L + 48 = 492
2L + 48 = 492
2L = 444
L = 222
Answer: Linda sold 222 boxes.
Check:
Penny sold 48 more boxes, so she sold 222 + 48 = 270.
Add the numbers they sold: 222 + 270 = 492
The difference is 48, and the total is 492. Our answer is correct.

solve pls i have more I WILL GIVE EXTRA POINTS!!!!!!!!!!
20+
2y + 12 = -3x
Step-by-step explanation:
Divide y y by 1 1 . Divide 12 12 by 2 2 . Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.

2 1/3 divided by 4/5
Answer: 2.91666666667
Answer:
(2 1/3) : (4/5) = 35 /12 = 2 11 /12
1. You convert the mixed number (2 1/3) into an improper fraction which is 7/3.
2.Then you find a new numerator so you multiply the whole number (2) by the denominator (3) which is 6.
3 Add the answer (6) to the starting numerator (1). The new numerator equation: 6+1=7.
4.Write the new numerator (7) over the denominator (3)
Two and one seven third is seven thirds.
5. Then you divide: 7/3 : 4/5 = 7/3 * 5/4 = 7*5/ 3*4
6. Multiply (7 and 5) and (3 and 4) which gives you 35/12.
7.Then you transform it back into a mixed number by dividing 35/12 which gives you 2 11/12.
I thought of a number, I added 1 3 4 to it, then I multiplied the result by 2 2 11 and I got 8. What was my number?
im sorry please hurry
Given:
In a number, adding [tex]1\dfrac{3}{4}[/tex], then multiplying the result by [tex]2\dfrac{2}{11}[/tex] we get 8.
To find:
The unknown number.
Solution:
Let the unknown number be x.
According to the question,
[tex](x+1\dfrac{3}{4})\times 2\dfrac{2}{11}=8[/tex]
[tex](x+\dfrac{1\times 4+3}{4})\times \dfrac{2\times 11+2}{11}=8[/tex]
[tex](x+\dfrac{4+3}{4})\times \dfrac{22+2}{11}=8[/tex]
[tex](x+\dfrac{7}{4})\times \dfrac{24}{11}=8[/tex]
Multiply both sides by [tex]\dfrac{11}{24}[/tex].
[tex]x+\dfrac{7}{4}=8\times \dfrac{11}{24}[/tex]
[tex]x+\dfrac{7}{4}=\dfrac{11}{3}[/tex]
Subtract [tex]\dfrac{7}{4}[/tex] from both sides.
[tex]x=\dfrac{11}{3}-\dfrac{7}{4}[/tex]
[tex]x=\dfrac{44-21}{12}[/tex]
[tex]x=\dfrac{23}{12}[/tex]
[tex]x=1\dfrac{11}{12}[/tex]
Therefore, the required number is [tex]1\dfrac{11}{12}[/tex].

The diagram shows changes of state between solid, liquid, and gas. The atoms of a substance lose energy during a change of state. Before the change, the atoms are close together but are able to slide past one another.
A diagram has a triangle at center with gas on top, liquid on bottom right, solid on bottom left. An arrow from gas to liquid is labeled O, and an arrow from liquid to gas is labeled N. An arrow from solid to liquid is labeled P, and an arrow from liquid to solid is labeled Q. An arrow from solid to gas is labeled L, and an arrow from gas to solid is labeled M.
Which arrow represents the change of state described above?
M

Step-by-step explanation:
A restaurant owner was experimenting with the taste of her homestyle lemon drink. She started with 60 litres of water. She removed 15 litres of the water and replaced it with 15 litres of pure lemon juice.
After thoroughly stirring the new mixture, she discovered that it was too “lemony”. So she removed 10 litres of the new mixture and replaced it with 10 litres of water. She thoroughly stirred the mixture and concluded that the new mixture was just right.
Determine the ratio of pure lemon juice to water in the final 60 litre mixture.
Answer:
ratio of pure lemon juice to water in the homestyle lemon drink is 5 : 19.
Step-by-step explanation:
In order to solve the final ratio of lemon juice to water, let us start by determining the initial ratio of pure lemon juice to water in the first mix. This is done as follows:
Total volume of mixture = 60 liters
initial volume of water = 60 liters
initial volume of lemon juice = 0 liters
1) She removed 15 liters of the water and replaced it with 15 liters of pure lemon juice.
Volume of water = 60 - 15 = 45 liters
Volume of lemon juice = 15 liters
[tex]\therefore \frac{15}{60}\ = \frac{1}{4}\ of\ the\ first\ mix\ is\ lemon\ juice\\\frac{45}{60}\ = \frac{3}{4}\ of\ the\ first\ mix\ is\ pure\ water[/tex]
2) She removed 10 liters of the new mixture
Let us convert this amount removed into ratio:
[tex]lemon\ juice\ = \frac{1}{4}\ \times 10 = \frac{10}{4} = \frac{5}{2}\ liters.\\ \therefore the\ owner\ removes\ \frac{5}{2}\ liters\ of\ pure\ lemon\ juice\\pure\ water\ = \frac{3}{4}\ \times 10 = \frac{30}{4} = \frac{15}{2}\ liters\\ \therefore\ the\ owner\ removes\ \frac{15}{2}\ liters\ of\ water\ from\ the\ first\ mix.[/tex]
New volumes of water and lemon juice after removing the 10 liters of mixture is calculated as follows:
[tex]lemon\ juice\ = 15 - \frac{5}{2} = \frac{30-5}{2} = \frac{25}{2}\ liters\ of\ lemon\ juice\\pure\ water\ = 45 - \frac{15}{2} = \frac{90-15}{2} = \frac{75}{2}\ liters\ of\ pure\ water[/tex]
3) and replaced it with 10 liters of water.
[tex]New\ volume\ of\ water\ = 10 + \frac{75}{2} = \frac{20+ 75}{2} = \frac{95}{2}\ liters[/tex]
The final ratio of lemon juice to water:
[tex]\frac{25}{2} : \frac{95}{2}\\= 25 : 95\\= 5 : 19[/tex]
Therefore, the final ratio of pure lemon juice to water in the homestyle lemon drink is 5 : 19.
6+7×4+34=56 are they equal
No its not, the equation your showing right now adds up to 68
Answer:

REASONING A newspaper company has three printing presses that together can produce 3500 newspapers each
hour. The fastest printer can print 100 more than twice the number of papers as the slowest press. The two slower
presses combined produce 100 more papers than the fastest press. How many newspapers can each printing press
produce in 1 hour?
Answer:
X = 1,700; Y = 1,000; Z = 800
Step-by-step explanation:
I could have sworn I answered this??? Sorry! Brainly, why wouldn't you let me answer this last night??? Anyway, for these types of problems, use X, Y, and Z for the three things you need to solve. First, we know that X (the fastest printer) = 100 + 2Z, where Z = the slowest printer. Z + Y = 100 + X or Z + Y = 100 + ( 100 + 2Z). --> Y - 200 = Z and Y = Z + 200. Next, we can add X + Y + Z together and set it equal to the full amount of newspapers, 3,500. Which would stand as 100 + 2Z + Z + 200 + Z = 3,500, let's try to solve for Z first, since it'll be super easy. We get 300 + 4Z = 3,500 --> 4Z = 3,200 --> Z = 800. Y = 200 + 800 = 1,000 and X = 100 + 2*800 = 1,700. And Z + Y = 800 + 1,000 = 1,800, which is 100 papers more than the fastest printer.
