Kellan’s lemonade recipe uses 4 scoops of lemonade powder for every 2.5 cups of water. Kellan uses 10 scoops of lemonade powder to make a batch of lemonade. How much water should he use?
Answer:
6.25 cups of water
Step-by-step explanation:
So I first write out the rates: 4:2.5 and also 10:?
So let's find out how the scoops changed, as in how did you get 4 to become 10 so you can do the same thing to 2.5 and get ?.
To go from 4 to 10 you MULTIPLY/DIVIDE. DON'T ADD OR SUBTRACT. 10 divided by 4 (to see what you multiplied by) is 2.5.
So we multiplied 4 by 2.5 to get 10. So if we multiply 2.5 by 2.5 we get 6.25.
So 4:2.5 = 10:6.25
?=6.25

During the first leg of a backpacking trip, a group of hikers covered 10.4 miles in 3 hours and 1 minute. The next day, the group hiked 8.6 miles in 3 hours and 47 minutes. What was the group's average speed over the two days? Answer as a decimal rounded to the nearest tenth.
Answer:
2.79 mi/hr ( for the time they were actually moving)
Step-by-step explanation:
average speed = total distance / total time
= ( 10.4 + 8.6 mi) / ( ( 181 + 227 min )/60 min/hr) =2.79 mi/hr

The sum of the angles in a triangle are 180 degrees. Find the value of the variable, then find the angle measures of a polygon.
Answer:
15=x 5x=75
Step-by-step explanation:
90/6=15
6 is how many x's there are in total meaning that 1 x = 15
15*5=75 so one angle is 15 while the other is 75
75 + 15= 90
90+90=180 getting you the 180 degrees

The longest side of the quadrilateral (in inches) is 29 inch.
Here,
The lengths of the four sides of a quadrilateral (in inches) are consecutive integers.
The perimeter is 110 inches.
We have to find the value of the longest side of the four side lengths.
What is Perimeter of quadrilateral?
The sum of all length of sides of a quadrilateral is called the Perimeter of quadrilateral.
Now,
The lengths of the four sides of a quadrilateral (in inches) are consecutive integers.
Let the length of quadrilateral are;
x, x + 1, x + 2 and x + 3
The longest length = x + 3
Since, The perimeter is 110 inches.
Hence,
x + (x + 1) + (x + 2) + (x + 3) = 110
x + x + 1 + x + 2 + x + 3 = 110
4x + 6 = 110
4x = 110 - 6
4x = 104
x = 26 inch
Hence, The longest length = x + 3 = 26 + 3 = 29 inch
Therefore, The longest side of the quadrilateral (in inches) is 29 inch.

Select an equation to solve the problem. Then solve. Joaquin is saving $369 to buy a surf board. He saved $9 each week for 11 weeks. He wants to buy the surf board in 9 more weeks. How much does Joaquin need to save each week? Let m be how much money Joaquin needs to save each week. Select an equation to solve the problem. ? Solve the equation. M = Answer the question. Joaquin needs to save $ each week.
Answer:
[tex]9m = 270[/tex]
[tex]m = \$30[/tex]
Joaquin needs to save $30 each week.
Step-by-step explanation:
Total money required for buying a surf board = $369
Money saved every week for first 11 weeks = $9
Total money saved in first 11 weeks = 11 [tex]\times[/tex] 9 = $99
Joaquin wants to buy the surf board in 9 more weeks.
To find:
Money to be saved each week for the next 9 weeks so that the surf board can be bought?
Solution:
Let the money to be saved each week for the next 9 months = $[tex]m[/tex]
Total money to be saved in the next 9 months = $9[tex]m[/tex]
Now, let us find the remaining amount of money to be saved by subtracting the total money saved from the cost of surf board. And then compare it with $9[tex]m[/tex].
[tex]369 - 99 = 9m\\\Rightarrow 9m = 270[/tex]
Solving the equation, we get:
[tex]m = \$30[/tex]
Therefore, Joaquin needs to save $30 each week.

The equation of the straight line is y = 2x + 6.
What is an equation of a line?An equation of a line is a mathematical expression that describes the relationship between the x and y coordinates of the points on the line. There are several different forms of the equation of a line, but the most commonly used is the slope-intercept form:
y = mx + b
where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
We have,
To find the equation of the straight line passing through the points (-3, 0) and (0, 6), we can use the slope-intercept form of a linear equation, which is:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We can first find the slope of the line using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
[tex]where ~(x_1, y_1) = (-3, 0) ~and ~(x_2, y_2) = (0, 6):[/tex]
So,
m = (6 - 0) / (0 - (-3)) = 6/3 = 2
Now we can substitute the slope and one of the points into the slope-intercept form to find the y-intercept:
y = mx + c
0 = 2(-3) + c
0 = -6 + c
c = 6
Therefore,
The equation of the straight line is y = 2x + 6.

Answer:
The main difference between a vascular and a non-vascular plant is that a vascular plant has vessels that can carry food and water to all the other parts of the plant. the arrangements of the cell in a non-vascular plant is also a lot simpler.

Step-by-step explanation:
f(x)=a(1+r)^{x}
f(x)=exponential growth function
a=initial amount
r=growth rate
{x}=number of time intervals
so let x=years
start amount is 1,500
1,500(1+r)^5=2100

In kickboxing, it is found that the force, f, needed to break a board, varies inversely with the length, l, of the board. If it takes 15 pounds of pressure to break a board that is 7 feet long, how many pounds of pressure will it take to break a board that is 5 feet long?
Answer:
21 pounds
Step-by-step explanation:
Given that f varies inversely with l then the equation relating them is
f = [tex]\frac{k}{l}[/tex] ← k is the constant of variation
To find k use the condition f = 15 when l = 7, then
15 = [tex]\frac{k}{7}[/tex] ( multiply both sides by 7 )
105 = k
f = [tex]\frac{105}{l}[/tex] ← equation of variation
When l = 5 , then
f = [tex]\frac{105}{5}[/tex] = 21 pounds
