Ratio and prooprtion
scale:actualdistance=5in:29mi
so
5:29=?:87
5/29=?/87
times both sides by 87
435/29=?
15=?
they would be 15in apart
To do this problem, you need to find how many questions per minute she can do. You would need to do 21 divided by 14. Which equals 1.5 questions per minute. From there you would do 1.5 times 30 and get 45.
So she can get 45 questions in 30 minutes.
Hope that helps!!
Answer:
Y=3x+2, Y= -3x-2
Step-by-step explanation:
If you need a consistent (parallel) line you must have very similar equations, with only positives and negatives being changed. If it's Y=3x+2, only the 2 is changed from negative to positive changing the lines position. If it's Y= -3x-2 then the X value is moved to a different coordinate and the -2 keeps the change.
Hope this helps and please critique what I've done if im wrong.
<h2>circumference = 50.24cm</h2><h2>area = 200.96cm²</h2>
Step-by-step explanation:
radius (r) = 8cm
circumference = 2π×r
= 2 × 3.14 × 8
= 50.24cm
area = π × r²
= 3.14 × 8 × 8
= 200.96cm²
<h2>MARK ME BRAINLIST</h2>
Answer:
The fabric needs 196.4 ft²
Step-by-step explanation:
∵ The tent formed formed from 4 faces
two equilateral triangles with side length 7 ft
two rectangles with dimensions 11 ft and 7 ft
∵ Area equilateral Δ = 1/4 S²√3
∵ Area rectangle = L × W
∴ The area of the prism = 2 × 1/4 × (7)²√3 + 2 × 7 × 11
= 196.4 ft²
Note:
If you find the area of the triangle by the rule 1/2 × base × height
∴ Area Δ = 1/2 × (7) × 6 = 21 ft²
∴ Area tent = 2 × 21 + 2 × 77 = 196 ft²
Two answer very closed
