PLEASE HELP How can the area of this triangle be determined by forming a rectangle? Select from the drop-down menus to correctly complete the statements. Copy and rotate the triangle and place it next to the existing triangle to form a rectangle. The length of the rectangle is (choose) 4,5,8,10 units. The width of the rectangle is (choose) 4,5,8,10 units. The area of the rectangle is (choose) 10,16,20,25 square units.
The area of the triangle is half the area of the rectangle, so the area of the triangle is (choose)
10,16,20,25
square units.

Just add a similar triangle from the opposite side

Area of triangle=20/2=10units^2Answer:
Length = 5
Width = 4
Area = 20
Triangle area = 10
Step-by-step explanation:
The length of the rectangle = the longest leg = 5 units
The width of the rectangle = the shortest leg = 4 units
The area of the rectangle = width x length = 4 x 5 = 20 units²
The area of the triangle = 1/2 the area of the rectangle = 20 ÷ 2 = 10 units²

Terry walks 1/4 mile each morning
and 2/4 mile each afternoon. How far does Terry walk in 3 days? Draw bar diagrams and write equations to solve
the problem
Answers
Answer:
1 1/2
Step-by-step explanation:
To solve this problem, we need to find how many miles Terry walks in one day. Then, we can multiply by 3 to find how far she walks in three days.
One day |
We need to add how much she walks in both the morning and afternoon. 1/4 + 2/4 = 3/4 miles.
Three days |
Now that we know how much Terry walks in one day, we need to find how much she walks in three days. Multiple by 3 to solve this.
3/4 * 3 = 6/4 = 3/2
You can write 3/2 as an improper fraction: 1 1/2.

as the first 2 lines show us : there is a linear relationship between minutes and words.
1 minute correlates to 250 words.
2 minutes correlate to 500 = 2×250 words.
so, we see, every minute represents 250 words.
therefore, 3 minutes (A) correlate to 3×250 = 750 words.

Johnny bought an oil painting originally priced at $80 but on sale for 50% off. After 10% sales tax, what was the total cost?
Answers
Answer:
Step-by-step explanation:
A sales tax is never applied until money actually changes hands.
So you need to start by taking 50% off.
50% 0f 80 dollars = 50/100 * 80 = 4000/100 = 40
So the cost of the painting = 80 - 40 = 40
Now apply the sales tax
10% of 40 dollars = 10/100 * 40 = 400/100 = 4
The total cost = 40 + 4 = 44 dollars
