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

Answers

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.

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.

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.

Answers

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.

Move constant & collect like terms

Solution

X=30

Other guy didn’t explain so here it is

The two angles are equal as they are vertically opposite. So, we will show that algebraically as
5x-30 = 4x

Now we solve the equation.

Subtract 4x from both sides to get 5x-30-4x=0

Now add 30 to both sides to get 5x-4x=30

Now do 5x-4x=x

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.

Answers

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.

14x43=602 babies

Step-by-step explanation:

Is this the whole context of the problem? Going off of the idea that 14 babies are born every year each year the amount of birds would increase by 14. For example after two years (14x2) there would be 28 birds then after three years (14x3) there would be 42 so on so forth.

602 because 14 times 43 equals 602 since she keeps have babies for the next 43 years
