A wallet contains 23 bills. All the bills are $1 bills and $5 bills. There are 7 more $1 bills than $5 bills. How much money does the wallet contain?

Answers

Answer:

Step-by-step explanation:

Let's say x is the number of $1 bills and y is the number of $5 bills. We know that:

x + y = 23

x = y + 7

We can use rearrange the second equation and add them together to find x. Then, we can plug x into any one of our equations to find y and calculate how much money is in the wallet.

x + y = 23

x - y = 7

2x = 30

x = 15 $1 bills

15 = y + 7

y = 8 $5 bills

15 * $1 + 8 * $5 = $15 + $40 = $55

A 55-gallon barrel was filled to the brim and was left out in the open. 12% of the water was lost after three days of evaporation. Find the volume of water in the barrel after three days.

Answers

Total amount=55 gallon
Loss of water=12%
Using formula,used/total*100
=12/55*100
=12/11*20
=12*20/11
=240/11
=21.81
Thus, 21 gallon of water was lost
And volume of water after 3 days=55-21.81=33.19

Martin used a coordinate plane to design the garden shown. Each unit on the grid represents 10 yards.

How many square yards will the garden be after it is built? What is the total AREA of the garden?

Answers

The best way to solve this is to break the shape up into areas you know how to solve.

Lets divide this into the big rectangle being separated from the smaller rectangle at the bottom.

To find the height of the big rectangle, subtract one y-coord of 30 from the other y-coord 80.

80-30=50

To find the length of the big rectangle, subtract one x-coord of 10 from the other x-coord of 100.

100-10= 90

Multiply these to get the area of the big rectangle:

90 x 50 = 4500 units squared

Next, find the smaller recatngle’s area by repeating the previous steps:

Height: 30-10 = 20
Length: 70-40 = 30

Now find the area:

20 x 30 = 600 units squared

Finally, add both of these areas up to find the total area for the original shape:

4500 + 600 = 5100 units squared

Hope this helped!

The metric system uses units such as meter, litre, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces.

The customary system: this system of measurement is primarily used in the United States, which include the inch, foot, mile, pound and cup. The metric system: the system of measurement is primarily used in science and in countries outside the United States, which include meter, kilometer, liter, gram and kilogram.

someone, please help me. I need this done by today. Also, if you do do it, can you write part a and then part B​

Part A:  step 1 is correct, step 2 is wrong.  Right side of the equation should be 12 - 21 = -9

Write and evaluate an expression that tells you to subtract 6 from 9 then subtract the difference from 12 and then multiply by 3 use at least two types of grouping symbols

Answers

Step-by-step explanation:

One possible expression using two types of grouping symbols is:

3 × [(12 - (9 - 6))]

This expression first subtracts 6 from 9 to get a difference of 3, then subtracts that difference from 12 to get a result of 9. Finally, it multiplies 9 by 3 to get a final answer of 27. The grouping symbols used are parentheses to group the subtraction of 6 from 9, and then another set of parentheses to group the subtraction of that difference from 12. The outermost grouping symbols are the multiplication symbol and the pair of brackets used for clarity.

3. Gary's backpack weighs 1.2 pounds. His math textbook weighs 3.75 pounds, and his science textbook weighs 2.85 pounds. How much will his backpack weigh with the math and science textbooks in it?

4. Steven made punch by mixing 2.8 liters of orange juice, 0.75 liters of pineapple juice, and 1.2 liters of sparkling water. How many liters of punch did Steven make?

Answers

#1:

Serena does not have enough albums to hold all the photographs.

Work:

40*36 = 1440

#2:

A group of 1,058 people is called in for jury duty.

Work:

A jury is made up of 12 jurors and 2 alternates.  

1 jury = 12 jurors + 2 alternates = 14 members

So, the number of complete juries that can be formed is

= 1058/14 = 75.57

#3:
Gary's backpack will weigh 7.8 pounds with the math and science textbooks in it.

Work:

Total weight = backpack weight + math textbook weight + science textbook weight

Total weight = 1.2 + 3.75 + 2.85

Total weight = 7.8 pounds

#4:

Steven made 4.75 liters of punch.

Work:

Liters of Punch = orange juice + pineapple juice + sparkling water

Liters of Punch = 2.8 + 0.75 + 1.2

Liters of Punch = 4.75

Question for points :3
The base of a parallelogram is 14 inches, The area of the parallelogram is 98 square inches. Find h the height of the parallelogram.

Answers

Answer:

7 inches

Step-by-step explanation:

The formula for the area of a parallelogram is given by A = bh, where A is the area, b is the base, and h is the height.

The parallelogram base is 14 inches, and the area is 98 square inches. Substituting these values into the formula, we get:

98 = 14h

Solving for h, we can divide both sides by 14:

h = 7

Therefore, the height of the parallelogram is 7 inches.

divide both sides by 14 and h=7

This Stem-and-Leaf Graph represents the students’ test scores in History. What is the median for the data in this Stem-and-Leaf plot?

A. 52
B. 59
C. 65
D. 73

Answers

Answer:

C. 65

Step-by-step explanation:

The 5 stem has scores of 52, 55, and 57.

The 6 stem has scores of 64, and 66.

The 7 stem has scores of 73, 75, and 79.

Together, the data is: 52, 55, 57, 64, 66, 73, 75, and 79.

The median is the middle number. We can cross out the two outside numbers and go in from there.

52 and 79 are crossed out. 55 and 75 are crossed out. 57 and 73 are crossed out.

When there are two numbers in the middle instead of one (ideally, the one left after this process is the answer), you go between those. Between 64 and 66 is 65.
