An image of a rhombus is shown.
a rhombus with a base of 18 centimeters and a height of 15 centimeters
What is the area of the rhombus?
66 cm2
132 cm2
135 cm2
270 cm2
Answer:
270 cm²
Step-by-step explanation:
The area of a rhombus can be calculated using the formula Area = base * height. In this case, the base is 18 centimeters and the height is 15 centimeters. So the area of the rhombus is:
Area = 18 * 15
So, Area = 270 cm².
The area of the rhombus is 270 cm².
The area of the rhombus given is; 279 cm².
What is the area of the rhombus?The area of a rhombus can be calculated using the formula;
Area = base * height.
Given that the base is 18 centimeters and the height is 15 centimeters. So the area of the rhombus is:
Area = 18 x 15
So, Area = 270 cm².
Therefore, area of the rhombus is 270 cm².

HURRY PLEASSE! Find the x-value of the solution in the following system of equations.
y – x = - 4
y = - 2x + 2
Group of answer choices
x = 2
x = 4
x = -5
x = -1
Step-by-step explanation:
Substitute the second equation into the first equation to eliminate y:
y - x = -4
-2x + 2 - x = -4 (Substitute y = -2x + 2)
-3x + 2 = -4
-3x = -6
x = 2
Therefore, the solution is x = 2.

The average in-state tuition in Florida for the 2018-2019 school year
was about $13,700. If the tuition is expected to increase by 15%, what is
the expected tuition for the 2019-2020 school year?
Answer:
$15755
Step-by-step explanation:
x=2019-2020 tuition
y=2018-2019 tuition
x= y + (15% of y)
x= 13700+ (15/100 × 13700)
x= 13700+ (2055)
x= 15755

Nathan asks his friends what fraction of an hour it takes each of them to get ro school. Use the data to create a line plot
Answer:
The order of the line graph is:
two 1/3 three 1/2 five 2/3
--------------------------------------------------------
Step-by-step explanation:
You need to find the common denominator for the fractions. In this case it would be 6.
1/3 = 2/6
1/2= 3/6
2/3=4/6
Then you count how many of each there are and create a line graph.
In a class in a middle school, there were 80 students. 30 percent were girls. How many of the class were boys. Awnser in percents.
Answer:
In a class of 80 students 30 are girls.
To Find:
The percentage of girls in the class is?
Solution:
The given problem can be solved using the concepts of percentages.
1. The total number of students in the class is 80, 30 are girls of the 80 members.
2. Percentage is given by the formula,
=> Percentage = (Favorable numbers x 100)/Total numbers,
3. Using the formula mentioned above the percentage can be calculated,
=> Percentage of girls = (30x100)/80,
=> (30x100)/80,
=> (3x100)/8,
=> (3x25)/2,
=> 75/2 = 37.5%.
Step-by-step explanation:
Answer:
70%
Step-by-step explanation:
If 30% of the class were girls, then 70% of the class must be boys (since 30% + 70% = 100%).
To find out how many students this represents, we can use the following formula.
70/100 * 80 = 56
So there were 56 boys in the class.
To express this as a percentage, we can calculate what percentage of the class the boys represent.
56/80 * 100 = 70%
Therefore, 70% of the class were boys.
A restaurant uses c cups of flour for baking rolls and 12 cups of flour for baking pies each day. Use the Distributive Property to write an expression for how much flour the restaurant uses in seven days.
Answer:
7c + 84
Step-by-step explanation:
To find how much flour the restaurant uses in seven days, we need to multiply the amount of flour used per day by 7. We can use the distributive property to simplify this expression by factoring out the common factor of "c + 12":
Flour used in 7 days = 7(c + 12)
Expanding the expression, we get:
Flour used in 7 days = 7c + 7(12)
Simplifying, we get:
Flour used in 7 days = 7c + 84
Therefore, the expression for how much flour the restaurant uses in seven days is 7c + 84.

Answer:
5/2, or 2.5 miles
Step-by-step explanation:
Monday - 3/4 mile
Wednesday - 1/2 mile
Thursday - 2/3 mile
Saturday - 7/12 mile
Take the common denominator and add (in this case it will be 12)
9/12 + 6/12 + 8/12 + 7/12 = 30/12 = 5/2
Gio walked 2.5 miles
Answer:
She walked 2 7/12 miles.
Step-by-step explanation:
To start, we have to make sure we can add each fraction. One multiple they all have in common is 12. So we will change the denominator to 12. Remember, what you do to one side you have to do to the other!
To turn 3/4 into a 12, multiply by 3. 3x3 is 9 and 4x3 is 12 so 9/12.
To turn 1/2 into a 12, multiply by 6. 1x6 is 6 and 2x6 is 12 so 6/12.
To turn 2/3 into a 12, multiply by 4. 2x4 is 8 and 3x4 is 12 so 8/12.
And 7/12 is already in 12ths.
From there, we have to add the numerators.
9 + 6 + 8 + 7 = 31.
Now we have 31/12. We have to simplify this into a mixed number.
31 goes into 12 two times.
So we have 2 and 7/12 miles.

A local jewelry store sells class rings, which it purchases for $60 each. The store engraves a name and date on the ring and sells it using a markup rate of 340%.
What is the markup rate in decimal form?
The markup rate is the constant of proportionality in the equation y=kx
. Write an equation that can be used to find the markup on the cost x
of a ring.
Use the equation to find the markup amount by substituting the cost of a ring for x
.What is the retail price of a ring?
During graduation week, the store is going to reduce the price to $184.80.
Calculate what percent the sale price is of the retail price.
Think of the retail price of the ring as 100%. How does the sale price compare to the retail price? What does this tell you about the markdown rate?
What is an equation in the form y=kx
that relates the sale price to the retail price x
?
