✧ω✧
To complete the table of equivalent ratios, we need to calculate the missing values based on the given ratios of servings and liters of punch. The ratio between servings and liters is 4:1, so we can use that to find the missing values. For 4 servings, there will be 1 liter of punch, and for 20 servings, there will be 5 liters of punch.
Explanation:To complete the table of equivalent ratios, we need to find the missing values. Let's fill in the missing numbers based on the given ratios:
Number of Servings:
8??20Liters of Punch:
24??From the given values, we can see that the ratio between the number of servings and liters of punch is the same. So, to find the missing values, we need to find a common ratio. Let's calculate:
8 servings / 2 liters = 4 servings / 1 liter
This means that for every 4 servings, there is 1 liter of punch. Based on this ratio, we can find the missing values:
For 4 servings, there will be 1 liter of punch.
For 20 servings, there will be 5 liters of punch.

ANSWER 1
An airplane flew at an average rate of 600 miles per hour from Tokyo to Seattle. Because of a strong headwind, the average rate of the return trip was only 480 mph. The round trip took 18 hours. Which equation can be used to determine the time for each leg? 600t = 480t 600t = 18 – t 600t = 480 – t 600t = 480(18 – t)
600t = 480(18 – t) should be it
Answer:
Option D. 600t = 480( 18-t )
Step-by-step explanation:
An airplane flew at an average rate of 600 miles per hour fro Tokyo to Seattle.
Let the airplane travels for t hours so distance covered by the airplane will be = speed × time
= 600t miles
Similarly, average speed in return trip was 480 mile/hour. So distance covered in return trip = speed × time
= 480 ( 18-t ) [ since time taken by plane in round trip was 18. So time taken in return trip will be ( 18-t) ]
Therefore, distance traveled in one trip = distance covered in return trip
600t = 480( 18-t )

Lori creates the following design for a T-shirt.
Lori found the areas of Triangle 1 and Rectangle 1. Find the areas of the remaining figures.
The area of Rectangle 1 is 8.68 square inches.
The area of Triangle 1 is 6.48 square inches.
The area of Rectangle 2 is ... square inches.
The area of Triangle 2 is ... square inches.
The area of the whole figure is ... square inches.
Solution-
From the figure,
AE = 2.4
EB = 2.8
BC = 11.7
Area of rectangle 1 = 8.68 sq.in
[tex]\Rightarrow FH \times HI=8.68[/tex]
[tex]\Rightarrow EB \times HI=8.68[/tex] (∵ sides of the rectangle 2)
[tex]\Rightarrow 2.8 \times HI=8.68[/tex]
[tex]\Rightarrow HI=3.1[/tex]
Area of Triangle 1 = 6.48 sq.in
[tex]\Rightarrow \frac{1}{2}\times AE \times EG= 6.48[/tex]
[tex]\Rightarrow \frac{1}{2}\times AE \times (EF+FG)= 6.48[/tex]
[tex]\Rightarrow \frac{1}{2}\times AE \times (EF+HI)= 6.48[/tex] (∵ sides of the rectangle 1)
[tex]\Rightarrow EF+3.1= 5.4[/tex]
[tex]\Rightarrow EF=2.3[/tex]
[tex]\Rightarrow BH=2.3[/tex] (∵ sides of the rectangle 2)
[tex]BC = BH+HI+IC[/tex]
[tex]\Rightarrow 11.7= 2.3+3.1+IC[/tex]
[tex]\Rightarrow IC=6.3[/tex]
The area of Rectangle 2,
[tex]=EB\times BH =2.8\times 2.3=6.44\ sq.in[/tex]
The area of Triangle 2,
[tex]\frac{1}{2}\times GI \times IC=\frac{1}{2}\times EB \times IC=\frac{1}{2}\times 2.8 \times 6.3=8.82\ sq.in[/tex]
The area of the whole figure = Area of Triangle 1 + Area of rectangle 1 + Area of Triangle 2 + Area of rectangle 2
= 6.48+8.68+8.82+6.44=30.42 sq.in

the length of a rectangle is 5 less than twice its width. if the perimeter is 26 meters, find the dimensions of the rectangle
The width of the rectangle is 6 meters and the length is 7 meters.
Explanation:To solve this problem, let's assume that the width of the rectangle is represented by w. The length of the rectangle can be written as 2w - 5. The perimeter of a rectangle is given by the formula P = 2l + 2w, where P represents the perimeter, l represents the length, and w represents the width. We are given that the perimeter is 26 meters, so we can set up the equation:
26 = 2(2w - 5) + 2w
Simplifying this equation gives:
26 = 4w - 10 + 2w
Combining like terms:
26 = 6w - 10
Adding 10 to both sides:
36 = 6w
Dividing both sides by 6:
w = 6
Therefore, the width of the rectangle is 6 meters. To find the length, substitute the value of w back into the expression for the length:
l = 2w - 5
l = 2(6) - 5
l = 7
So the dimensions of the rectangle are width = 6 meters and length = 7 meters.

The problem is solved by setting up an algebraic equation based on the given pointers about the rectangle's width, length, and perimeter. After solving it, we find that the rectangle's dimensions are: width=6 meters and length=7 meters.
Explanation:
This is a problem of algebra within the subject of Mathematics. The width and length of the rectangle are the unknowns we need to find.
Given in the problem, the length is '5 less than twice its width'. If we denote the width as 'x', the length can be expressed as '2x - 5'. The equation for the perimeter of a rectangle is '2(length + width)', which equals 26 in this case. So we can set up our equation as follows: 2(x + 2x - 5) = 26.Solving this equation step-by-step:
Firstly, unfold the parentheses - 2x + 4x - 10 = 26, Then combine like terms to simplify it into 6x - 10 = 26. Add 10 to both sides of the equation to isolate the term with 'x', which results in 6x = 36. Finally, divide by 6 on both sides to find the value of 'x', so x=6. Substituting x=6 into the expression for the length, we find the length to be 2*6 - 5 = 7.Therefore, the dimensions of the rectangle are width=6 meters and length=7 meters.

Solve. Note the equal sign. What you do to one side, you do to the other. Remember to follow PEMDAS.
First, distribute 5 to all terms within the parenthesis
5(w - 1) = (5)(w) + (5)(-1) = 5w - 5
Next, simplify. Combine like terms
5w - 5 - 2 = 5w + 7
5w - 7 = 5w + 7
Next, isolate the variable. Add 7 to both sides, and subtract 5w from both sides
5w (-5w) - 7 (+7) = 5w (-5w) + 7 (+7)
5w - 5w = 7 + 7

Matthews bother has d dollars. Matthew has 5 more than twice the number of dollars his brother has. If Matthew has $35, how much does his brother have? I will give you 100 points!!
It should be 75 or 15?
The equation to this problem would be (2n+5=d)?
So since Mathew has twice the number of dollars his brother has, you would replace n with 35. 2*35=5=d which equals 70+5=75. But I don't really understand what the question is asking, so it could be 15 too.

Jimmy knows that to pass the fitness test he needs to be able to run 5 kilometers in 35 minutes. His pace monitor measures in miles. If he can run 3 miles in 35 minutes, will he pass his fitness test? Why or why not?
A) Yes, he will pass because he is running 5.2 km in 35 minutes.
B) Yes, he will pass because he is running 8.7 km in 35 minutes.
C) No, he will not pass because he is running 4.8 km in 35 minutes.
D) No, he will not pass because he is running 1.875 km in 35 minutes.
Jimmy, who can run 3 miles (roughly equivalent to 4.8 km) in 35 minutes, will not pass the fitness test as it requires running 5 kilometers in the same period.
Explanation:The question is asking if Jimmy can pass the fitness test of running 5 kilometers in 35 minutes if he can run 3 miles in the same amount of time. In order to answer this question, we need to convert miles to kilometers. One mile is approximately equal to 1.60934 kilometers. So if Jimmy runs 3 miles, that's equivalent to 3 * 1.60934 = 4.82802 kilometers.
Therefore, the correct answer is C) No, he will not pass because he is running 4.8 km in 35 minutes. Despite his good effort, Jimmy is running less than the required 5 kilometers in 35 minutes based on the fitness test standards.

Jimmy will not pass his fitness test by running 3 miles in 35 minutes, as this converts to approximately 4.82802 kilometers, which is less than the required 5 kilometers. Option C) is the correct answer.
Jimmy needs to know if running 3 miles in 35 minutes will allow him to pass his fitness test, which requires him to run 5 kilometers in 35 minutes. To determine if he will pass, we need to convert miles to kilometers. Since 1 mile is approximately 1.60934 kilometers, we multiply 3 miles by this conversion factor:
3 miles imes 1.60934 km/mile = 4.82802 km
So, Jimmy runs approximately 4.82802 kilometers in 35 minutes. Comparing this to the fitness test requirement of 5 kilometers in 35 minutes:
4.82802 km < 5 km
Thus, Jimmy will not pass the fitness test based on his current pace, as he runs just under the required distance in the allotted time.
The answer to the question is: C) No, he will not pass because he is running 4.8 km in 35 minutes.

Step-by-step explanation:
A rectangle has a width of 7.9 feet and a perimeter of 27.2 feet.
Let the length be = x
Perimeter is given by :
[tex]P=2(L+W)[/tex]
We get;
[tex]27.2=2(x+7.9)[/tex]
=> [tex]27.2=2x+15.8[/tex]
=> [tex]2x=11.4[/tex]
Dividing both sides by 2 to get x;
x = 5.7 feet
Hence, length is 5.7 feet.
A race horse that wins three 3200 meter cup in a time of 200 seconds. what is the race horses Average speed?
Answer:
16 meter per second.
Step-by-step explanation:
A race horse that wins three 3200 meter cup in a time of 200 seconds.
Since in 200 seconds horse can run = 3200 meter
Therefore, in 1 second horse can run = [tex]\frac{3200}{200}[/tex]
= 16 meter/second
1 hour = 3600 seconds
Therefore in 1 hour horse can run = 3600 × 16
= 57,600 meter/hour
The average speed of the horse would be 16 meter per second or 57,600 meter per hour.
Joe says that the product of a 4 digit number and a 1 digit number is always a 4 digit number does Joe's statement makes sense?
No, what Joe said isn't necessarily true. Though it is common that the product will be a 4 digit number, because you can use any number, like a large 4 digit number like 9999 or a large 1 digit number like 9, that isn't true. For instance: "9999 x 9" is 89991 which is 5 digits instead of 4 because "9999" is the biggest 4 digit number and "9" is the biggest "1" digit number.

In one season, the top four players on one major league team had batting averages of 0.332, 0.361, 0.343, and 0.368. Which is the highest average?
the highest average is 0.368
Answer:
0.368 is the highest average.
Step-by-step explanation:
We have been given the batting averages of the 4 top players on one major league team as 0.332, 0.361, 0.343, and 0.368. We are asked to choose the highest average from given choices.
Let us represent our given averages as fractions as:
[tex]\frac{332}{1000},\frac{361}{1000},\frac{343}{1000},\frac{368}{1000}[/tex].
Now we can see that 1st player hit 332 in 1000 at bats, 2nd player hit 361 in 1000 at bats, 3rd player hit 343 in 1000 at bats and 4th player hit 368 in 1000 at bats.
Clearly, 368 is the greatest number of our given choices, therefore, the highest average is 0.368.
