What percent of 110 is 71.5?

polet [3.4K]

Answer:

65%

Step-by-step explanation:

A percentage OF something is the operation of multiplication, so you would use division [inverse of multiplication] to figure this out:

$\frac{13}{20} = \frac{71\frac{1}{2}}{110}$

* $\frac{13}{20} = 0,65 =$ 65%

* $71\frac{1}{2} = 71,5$

** To convert a decimal to a percentage, you move the decimal mark TWICE TO THE RIGHT. So with that being said, you have your answer.

I am joyous to assist you anytime.

Select the statements that are true for the graph of y=−(x−0.5)2+9 . Choose all correct statements. The vertex is (−0.5,9) . The

Lapatulllka [165]

Answer:

Second and last

Step-by-step explanation:

The vertex form of a quadratic function is written as: a(x-h)^2+k where (h,k) are the coordinates of the vertex

The equation y =-(x-0.5)^2+9

Then the vertex of this graph is (0.5,9)

◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇

The equation -(x-0.5)+9 has a negative leading factor so the parabola will open down then it will have a maximum

Can y’all help me on this one What’s the answer?

Rudik [331]

Answer:

x = 2

Step-by-step explanation:

First translate the image into an equation using the key. Once you do that, your equation should look like this:

(x + x + x) + (-1 + -1 + -1 + -1 + -1) = (-x + -x) + (1 + 1 + 1 + 1 + 1)

________________________________

3x - 5 = -2x + 5

(given)

________________________________

3x - 5 = -2x + 5

+5. +5

(addition property of equality)

*cancel out -5 on the left hand side, and isolate it from x by adding +5 on each side*

__________________________

3x = -2x + 10

+2x +2x

(addition property of equality)

*cancel out the negative 2x, and isolate it from the constant term on the right hand side by adding 2x on both sides*

________________________________

5x = 10

÷5. ÷5

(division property of equality)

*divide by 5(GCF) on both sides to isolate

x by itself*

________________________________

x = 2

________________________________

If you want to test this solution, substitute this back into the equation.

x = 2 → 3x - 5 = -2x + 5. 3(2) - 5 = -2(2) + 5 = 6 - 5 = -4 + 5 = 1 = 1

Factor and solve the problems in the photo ……….. pleaseeeee help i haven’t done algebra in 2 years

vladimir1956 [14]

Answer:

30. 2x²-x-1=0

or, 2x²-2x+x-1=0

or, 2x(x-1)+1(x-1)=0

or, (x-1)(2x+1)=0

so, x-1 = 0 or, x = 1

and 2x+1 = 0 or, 2x = -1 or, x = -1/2

so, x = 1 and 1/2

31. 3x²-14x=5

or, 3x²-14x-5=0

or, 3x²-15x+x-5=0

or, 3x(x-5)+1(x-5)=0

or, (x-5)(3x+1)=0

so, x-5=0 or, x=5

and 3x+1=0 or, 3x=-1 or, x=-1/3

so, x = 5 and -1/3
