Find the area of the figure and choose the appropriate result.
1 m
3.5 m
8 m
Answer:
Area if figure = 22 m²
Step-by-step explanation:
Given:
Length of rectangle = 8 m
Width of rectangle = 1 m
Base of triangle = 8 m
Height of triangle = 3.5 m
Find:
Area if figure
Computation:
Area if figure = Area of rectangle + Area of triangle
Area if figure = [l x b] + [(1/2)(b)(h)]
Area if figure = [8 x 1] + [(1/2)(8)(3.5)]
Area if figure = 8 + 14
Area if figure = 22 m²

The surface of a rectangular table has a perimeter 20 feet. Its area is 21 square feet. What are the dimensions of the table?
Answer:
7 and 3
Step-by-step explanation:
We know that all 4 sides have to add up to 20 and that 2 of the sides are the same because it's a rectangle. To find the area, we have to do length times width. Two different sides have to equal 21 when multiplied. The factors of 21 are 1, 3, 7, and 21. Let's try 1 and 21. We need an area of 21. 1 x 21 = 21 so it satisfies that. Now let's find the perimeter.21 + 21 + 1 + 1 = 44, but we need an perimeter of 20. Now, let's try 7 and 3. 7 x 3 = 21, so it satisfies the area. 7 + 3 + 7 + 3 = 20, so it also satisfies the perimeter. Therefore, 7 and 3 are the dimensions of the table.

Lisa purchased almonds for $3.00 per pound and she spent $24.90. How many pounds of almonds did she purchase? The price went up to $3.50 a pound and lisa only had 25.00 how many pounds of almonds can she buy and whats her chance?
Answer:
1. Lisa purchased almonds for $3.00 and spent $24.90.
The quantity of almonds bought is therefore:
= Total amount spent / Cost per pound
= 24.90 / 3
= 8.3 pounds
2. If the price goes up to $3.50 per pound and the maximum Lisa can spend is $25, the number of pounds she can get is:
= Maximum amount for almonds / Price per almonds
= 25 / 3.5
= 7.14 pounds

If you didn't know an exterior angle of a triangle is equal to the sum of its opposite interior angles
to be more specific ∠5=∠4+∠3
we are given ∠5 and ∠4 and we need to find ∠3
So we plug in what we have and solve for ∠3
130 = 70 + ∠3
subtract 70 from each side
130 - 70 = 60
we're left with ∠3 = 60

Veronikas five test scores are 59 80 95 and 93 if the outlier of 59 is removed what is the mean absolute deviation of the remaining four test scores?
Complete Question
Veronikas four test scores are 59, 80, 95, 88 and 93 if the outlier of 59 is removed what is the mean absolute deviation of the remaining four test scores?
Answer:
5
Step-by-step explanation:
We have the four test scores
80, 95, 88 and 93
Step 1
We find the mean of the 4 test scores
= 80 + 95 + 88 + 93/4
= 356 / 4
89
Step 2
The formula for Mean Absolute Deviation =
Summation( x - Mean)/n
Hence,
|(80 - 89 )+( 95 - 89) + (88 - 89) + (93 - 89)|/5
= 9 + 6 +1 + 4/4
= 20/4
= 5

Makenzie got a $30 gift certificate to the local theater for her birthday. Adult tickets (x) cost $8.00 and tickets for children (y) cost $4.50. Which inequality represents the number of adults and children who can go to a show using the $30 gift certificate?
The inequality that represents the number of adults and children who can go to a show using the $30 gift certificate is:
x < 4 and y < 7.
Where x is the number of children and y is the number of adults.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Makenzie got a $30 gift certificate to the local theater for her birthday. Adult tickets (x) cost = $8.00
Children's tickets (y) cost = $4.50
Now,
The number of children who can go to the theater.
4.50y = 30
y = 30/4.50
y = 6.67
This means,
y < 7 _____(1)
Now,
The number of adults who can go to the theater.
8x = 30
x = 30/8
x = 3,75
x < 4 ______(2)
Thus,
From (1) and (2).
The inequality represents the number of adults and children
x < 4 and y < 7.
