Can you explain how to do 7-11 or do them please

Mathematics
1 answer:
lawyer [7]3 years ago
6 0

Answer:

Step-by-step explanation:

A good thing to remember here is that the word "is" generally means "equals" and the word "of" generally means to multiply.  For #7, "15 is" translates to

15 =

"3/8 of" translates to

15 = 3/8 ×

"of what number" is our unknown, so

15 = 3/8x.  Solve it by multiplying both sides by 8/3.

#8.  "Seventy is" is 70 =

"what decimal part" is our unknown x,

"of 200" is ×200, so

70 = 200x.  Solve that by dividing both sides by 200.  Leave it in a decimal since it asks for the decimal part.

#9. "Two-fifths of" is 2/5 ×

"what number" is our unknown x, and

"is 120" is = 120, so

2/5x = 120.  Solve that by multiplying both sides by 5/2.

#10. Read "what is 60% of 180" to get x = .60(180)

#11.  Read "what is 20% of 35" to get x = .20(35)

Multiply both 10 and 11 to get the answers.

Determine the inverse of f(x)=3x+4 algebraically
Fed [463]

Answer:

1/3x +4

is the inverse of f(x) = 3x + 4.

Check:

The purpose of the inverse property of multiplication is to get a product of one. So the inverse multiplied with the original number (or equation) should give us the product of one.

1 / (3x + 4) * 3x + 4 = 3x+4 / 3x+ 4 = 1

Two sides of the given triangle are equal. Therefore, the given triangle is an isosceles triangle.

Option (B).

Given triangle has a right angle. Therefore, it's a right triangle.

Option (C).

Only two sides of the given triangle are equal. Therefore, it's not an equilateral triangle.

Option (D).

Although this triangle has two acute angles (less than 90°) but the third angle is 90°. Therefore, this triangle is not an acute triangle. It's a right triangle.

Option (E).

A scalene triangle is a triangle having all sides different in measure but the given triangle is an isosceles triangle. Therefore, it's not a scalene.

Option (F).

Any angle of this triangle is not more than 90°. Therefore, the given triangle is not an obtuse triangle.
