This one is extremely simple, and we can use the color coded pie chart to find the cost of each of the 5 things.
For the first, decorations, Mary spent $?? as shown by the blue triangle on the pie chart. Let’s get the other ones first to total the money left over.
For the second, she spent $65 on food, as shown by the green triangle on the pie chart.
For the third, she spent $80 on party hall rental, as shown by the blue triangle on the pie chart.
For the fourth, she spent $30 on prizes, as shown by the dark blue triangle.
And for the fifth one, she spent $45 on invitations. A bit too expensive if you ask me.
Then we add all the costs together, and get 220. After adding the extra costs such as candy, costumes, and music, we get a total of $345. We would subtract this from $375 to get a total of $30 left over, which was spent on decorations. The ??? value of the light blue triangle is $30.
Hope this helps!
Answer:
250 minutes of calling will cost same using both plans.
$53
Step-by-step explanation:
Please consider the complete question.
A phone company offers two monthly plans. Plan A costs $23 plus an additional $0.12 for each minute of calls. Plan B costs $18 plus an additional $0.14 of each minute of calls. For what amount of calling do the two plans cost the same? What is the cost when the two plans cost the same?
Let x represent the number of call minutes.
The total cost of calling for x minutes using plan A would be cost of x minutes plus fixed charge that is 
.
The total cost of calling for x minutes using plan B would be cost of x minutes plus fixed charge that is 
.
To find the number of minutes for which both plans will have same cost, we will equate total cost of x minutes for both plans and solve for x.
Therefore, calling for 250 minutes will cost same using both plans.
Upon substituting in expression , we will get:
Therefore, the cost will be $53, when the two plans cost the same.
Answer:
12 pizzas were ordered and Maribel only has 108 dollars.
12x12=144, 144-108=36, meaning that Maribel needs 36 more dollars for the whole number of pizzas. She could only get 9 pizzas instead of 12 because 12x9=108.

Answer:
The answer to your question is the letter A. 20 ft²
Step-by-step explanation:
Data
length of a side = 10 ft
length of the diameter = 10 ft
length of the radius = 5 ft
Process
1.- Calculate the area of the square
Area of the square = side x side
= 10 x 10
= 100 ft²
2.- Calculate the area of the circle
Area = πr²
Area of the circle = (3.14)(5)²
Area of the circle = 78.5 ft²
3.- Calculate the remaining area
Remaining area = 100 - 78.5
Remaining area = 21.5 ft² ≈ 20 ft²
