Emilia and Darnell are arguing over who makes the best fruit punch. Emilia likes to use 2 cups of grape juice for every 5 cups of pineapple juice. Darnell prefers to use 1 cup of grape juice for every 4 cups of pineapple juice. Do Emilia and Darnell use the same ratio of grape juice to pineapple juice?
Answer:
No
Step-by-step explanation:
Emilia = 2 cups of grape juice for every 5 cups of pineapple juice
We can simplify this to 1 cup of grape juice for every 2 1/2 cups of pineapple juice
Darnell = 1 cup of grape juice for every 4 cups of pineapple juice
You can see the difference

Water flows to wish sprinkler at 25 gallons every 10 minutes how much water would flood the sprinklers in 3 hours
Answer:
Water in 3 hours = 450 gallons
Step-by-step explanation:
Given that:
Water flows at a rate of 25 gallons in 10 minutes.
10 minutes = 25 gallons
1 minute = [tex]\frac{25}{10}[/tex] = 2.5 gallons
Now,
Time = 3 hours
3 hours = 180 minutes
Quantity of water in 3 hours = 2.5 * 180
Quantity of water in 3 hours = 450 gallons
Hence,
Water in 3 hours = 450 gallons

Please help!!! Name the property of equality or congruence that justifies going from the first statement to the second statement.
Answer:
The property of equality that justifies going from the first statement to the second statement is;
Subtraction property of equality
Step-by-step explanation:
The given equation is presented here as follows;
AB + BC = 42
AB = 42 - BC
The above equation can be simplified as follows;
AB + BC = 42
AB + BC - BC = 42 - BC
(+ BC - BC = 0)
Therefore, we have;
AB + BC - BC = AB + 0 = AB = 42 - BC
AB = 42 - BC which is the subtraction property of equality
For the subtraction property of equality, when we subtract a value from one side of the equation, we must subtract the same value from the side of the equation as follows
Given that the letters a, b, and c represent any numbers
When we have;
a = b
Then we also must have;
a - c = b - c
Rectangle JKLM is congruent to a 4 inch by 7 inch rectangle. How many different values are possible for the length of Segment J M? one two three four
Answer:
two
Step-by-step explanation:
In the case when there is a congruent rectangle so that represent the equal sides i.e. the width and the length would be the same.
Since it is mentioned that one rectangle JKLM has 4 inch and 7 inches dimension so there would be the possibility that the length of J M might be 4 or 7
So here the possibility of the length is two
Answer:
b: two

List a, b, and c for the following Quadratic: x^2 – 3x = 0
Answer:
a = 1, b = - 3, c = 0
Step-by-step explanation:
The standard form of a quadratic equation is
ax² + bx + c = 0 ( a ≠ 0 )
compare x² - 3x = 0
with a = 1, b = - 3, c = 0
The Benton family uses up a 1/2 gallon jug of milk every 3 days. At what rate do they drink milk?
Answer:
1/6
Step-by-step explanation: in a rate you need to make it a one so you double the 1/2 gallon to make it one gallon then since you doubled that you have to double the days to 6. So they drink 1 gallon per 6 days.
Look at this triangle . Work out the length of AB . One of angles is 4 and other is 11
Answer:
7 < AB < 15
Step-by-step explanation:
AB > 11-4, AB > 7
AB < 11+4, AB < 15
so 7 < AB < 15

Four points partition the directed line segment from A to B. • Point P partitions the directed line segment from A to B into a 3:4 ratio. • Point Q partitions the directed line segment from A to B into a 4:3 ratio. • Point R partitions the directed line segment from A to B into a 2:5 ratio. • Point S partitions the directed line segment from A to B into a 5:2 ratio. A number line has points A and B. A line is drawn from point A to point B. Which point will lie closest to B? P Q R S
Answer:
S is closest to B.
Step-by-step explanation:
Given a directed line segment from point A to B.
Point P divides the line A to B in a ratio 3:4.
Point Q divides the line A to B in a ratio 4:3.
Point R divides the line A to B in a ratio 2:5.
Point S divides the line A to B in a ratio 5:2.
To find:
The point which is closest to the point B.
Solution:
Here, to find the point closest to B we need to find the distances PB, QB, RB and SB.
We can see the sum of ratio 3:4, 4:3, 2:5 and 5:2 is 7.
Let the distance between A and B be 7 units.
Now, the distances can be found easily.
[tex]PB = \dfrac{4}{7}\times 7 = 4\ units[/tex]
[tex]QB = \dfrac{3}{7}\times 7 = 3\ units[/tex]
[tex]RB = \dfrac{5}{7}\times 7 = 5\ units[/tex]
[tex]SB = \dfrac{2}{7}\times 7 = 2\ units[/tex]
The point which has the minimum distance from point B, will be nearest to B.
We can clearly observe that SB is the minimum distance.
Therefore, S is closest to B.
The closest point to point B on the line AB is point S
The ratios are given as:
P = 3 : 4
Q = 4 : 3
R = 2 : 5
S = 5 : 2
Given that the point is from A to B, the first ratio proportion represents the position of each point between A and B
So, we remove the second ratio proportion of the above ratios
P = 3
Q = 4
R = 2
S = 5
The point with the highest value is S i.e. 5
Hence, point S is the closest to point B

Classify each pair of numbered angles.
Drag and drop the descriptions into the boxes to correctly classify each pair of numbered angles. Each description may be used more than once.
Answer:
Angles 1 & 2 are vertical angles, and angles 3 & 4 are adjacent angles.
Step-by-step explanation:
Vertical angles are angles across from each other. Adjacent angles are always beside each other.
It's not a linear pair because a linear pair is adjacent angles that add up to 180°, which is not true for your 2 angles in the picture. Hope this helps!!!

What is the vertex of m2 - 20m + 72 = -3?
Answer:
m2−20m+72=−3
Step 1: Subtract -3 from both sides.
m2−20m+72−(−3)=−3−(−3)
m2−20m+75=0
Step 2: Factor left side of equation.
(m−5)(m−15)=0
Step 3: Set factors equal to 0.
m−5=0 or m−15=0
m=5 or m=15
Answer:
m=5 or m=15
A fruit company sells two types of boxes large and small. A delivery of two large boxes and three small boxes has a total weight of 47 kilograms. A delivery of six large boxes in 5 small boxes has a total weight of 115 kg. How much does each type of box weigh?
Answer:
the large box weight is 6.50 kg and the small box weight is 13.75 kg
Step-by-step explanation:
The computation of each type of box weight is as follows:
Let us assume the large box be x
And, the small box be y
So,
2x + 3y = 47.......(i)
6x + 5y = 115........(ii)
Multiply by 3 in equation 1
6x + 9y = 141
6x + 5y = 115
Now subtract the last equation from the above one
4y = 26
y = 6.50
For x, it would be
2x+ 3(6.50) = 47
2x + 19.5 = 47
2x = 47 - 19.50
2x = 27.50
x = 13.75
Hence, the large box weight is 6.50 kg and the small box weight is 13.75 kg
Let t represent an unknown number. What is the value
oft such that: t^2 x^3– 3tx + 6 is divisible by x+3.
There are two possible answers:
t = 2/3 or t = -1/3
========================================================
Explanation:
The expression x+3 is the same as x-(-3). It is of the form x-k
Recall that by the remainder theorem, we know that p(x) is divisible by (x-k) if and only if p(k) = 0.
In this case, k = -3. Plug this into the p(x) function and we get
p(x) = t^2*x^3 - 3t*x + 6
p(-3) = t^2*(-3)^3 - 3t*(-3) + 6
p(-3) = -27t^2 + 9t + 6
Set that equal to 0
p(-3) = 0
-27t^2 + 9t + 6 = 0
-3(9t^2 - 3t - 2) = 0
9t^2 - 3t - 2 = 0
Now apply the quadratic formula to solve for t
[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-(-3)\pm\sqrt{(-3)^2-4(9)(-2)}}{2(9)}\\\\t = \frac{3\pm\sqrt{81}}{18}\\\\t = \frac{3\pm9}{18}\\\\t = \frac{3+9}{18}\ \text{ or } \ t = \frac{3-9}{18}\\\\t = \frac{12}{18}\ \text{ or } \ t = \frac{-6}{18}\\\\t = \frac{2}{3}\ \text{ or } \ t = -\frac{1}{3}\\\\[/tex]
We get two possible solutions for t.
