Answer 1

Answer:

Mr. Crosgrove tipped $3.84.

120 pens are not red pens.

She had to pay $270 in taxes.

Step-by-step explanation:

So, to find the percentage of something you convert the percentage to a decimal and then multiply.

For #1

He spent $48, and tipped 8%

to turn 8% into a decimal you bring in down two place values, so it is 0.08. You multiply 48 * 0.08 and you get 3.84.

Mr. Crosgrove tipped $3.84.

For #2

He has 150 flair pens and 20% are red. Multiply 150 by 0.2. You will get 30. Now we know that there is 30 red pens, but the problem is asking how much is not red pens. subtract 150-30 and you get 120, so that is the answer.

120 pens are not red pens.

For #3

She has $2,000 and had to pay 13.5% You have to turn 13.5% into decimal so bring place value down by two so it is now 0.135. Multiply 2,000*0.135 and you get 270.

She had to pay $270 in taxes.

Hope this helps!!

Solve the inequality.

−78≤m−138
The solution is

Answers

m=60
You add 138 to both sides

Answer:

M = 60

Step-by-step explanation:

You are doing the opposite to each side to simplify the inequality so on one side it is the variable in your case, it is m and the other side is your number. You are going to add 138 to both sides and then you get your answer.

-78 ≤ M - 138

-78 + 138 ≤ M - 138 +138

60 ≤ M

M ≥ 60

Please help how do you solve this?

Answers

Answer:

A, 120 degrees

Step-by-step explanation:

Answer: A) 120 degrees

=============================================================

Explanation:

Triangle ABC is equilateral, so all three sides are the same length. This means the three angles are also the same measure. Call each interior angle x.

The three angles add to 180, so x+x+x = 180 solves to x = 60. Each interior angle is 60 degrees.

Angle DAC is an exterior angle of measure 180-x = 180-60 = 120 degrees

------------

Or another method you could use is the fact that all exterior angles of any polygon add to 360.

Since we have n = 3 sides, this means each exterior angle of an equilateral triangle is 360/n = 360/3 = 120 degrees

We consider this a regular polygon because all sides are the same length and all angles are the same measure. So the formula for the exterior angle measure 360/n would apply to any regular polygon and not just triangles.

An object’s height is measured in centimeters and in inches. Two rulers, one showing inches, the other showing centimeters. The rulers are aligned at zero. An arrow extends from the one inch mark on the first ruler toward the equivalent length on the other ruler, with the caption, one inch equals two and fifty-four hundredths centimeters. Write an equation that relates the number of centimeters c to the number of inches i. Determine the height in centimeters of a chair that is 32 inches tall. Enter the correct answers in the boxes.

Answers

If an object’s height is measured in centimeters and in inches. the height of the chair in centimeters is 81.28 cm.

How to find the height?

We know that one inch is equivalent to two and fifty-four hundredths centimeters. We can write this as:

1 inch = 2.54 centimeters

To find the equation that relates the number of centimeters c to the number of inches i, we can use this conversion factor:

c = 2.54i

This equation tells us that the number of centimeters is equal to 2.54 times the number of inches.

To find the height in centimeters of a chair that is 32 inches tall, we can plug in i = 32 into the equation above:

c = 2.54i

c = 2.54(32)

c = 81.28

Therefore, the height of the chair in centimeters is 81.28 cm.

So:[tex](4+7)(8)/2\\=11(4)\\=44 (cm)^{2}[/tex]

The area of the Triangle is (Base)(Height)/2

So:[tex](6)(10)/2\\=30(cm)^{2}[/tex]

Well, 44 is larger than 30, so the answer's D!!!

The function g is defined by g(x) = -3x + 2. Which statements are true? Select ALL that apply.
f{-2) is greater than g(-2).
f{-1) is less than g(-1).
f{0) is greater than g(0)
f(1) is less than g(1).
f(2) is greater than g(2).

Answers

Answer:

f{0) is greater than g(0) and f(2) is greater than g(2).

Step-by-step explanation:

f{0) is greater than g(0) = f(0)=8 and g(0)=2

f(2) is greater than g(2) = f(2)=8 and g(2)= -4

The two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).

What is the general equation of parabola?

The general equation of a parabola is given as,

[tex]y=a(x-h)^2+k[/tex]

where (h,k) is the coordinate of the vertex of the parabola.

The equation of the parabola with vertex (1,9) can be written as,

[tex]y=a(x-h)^2+k\\\\y=a(x-1)^2+9[/tex]

Now, the value of a can be found by putting one zero of the parabola,

[tex]y=a(4-1)^2+9\\\\0=a(3)^2+9\\\\-9=a(3)^2\\\\-9=a9\\\\a=-1[/tex]

Thus, the equation of the parabola can be written as y=-(x-1)²+9.

A.) The value of the two functions when the value of x is -2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-2)=-(-2-1)^2+9\\\\f(-2)=0[/tex]

[tex]g(x) = -3x + 2\\\\g(-2) = -3(-2) + 2\\\\g(-2)=8[/tex]

Therefore, f(-2) is less than g(-2).

B.) The value of the two functions when the value of x is -1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-1)=-(-1-1)^2+9\\\\f(-2)=5[/tex]

[tex]g(x) = -3x + 2\\\\g(-1) = -3(-1) + 2\\\\g(-1)=5[/tex]

Therefore, f(-1) is equal to g(-1).

C.) The value of the two functions when the value of x is 0 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(0)=-(0-1)^2+9\\\\f(0)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(0) = -3(0) + 2\\\\g(0)=2[/tex]

Therefore, f(0) is greater than g(0).

D.) The value of the two functions when the value of x is 1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(1)=-(1-1)^2+9\\\\f(1)=9[/tex]

[tex]g(x) = -3x + 2\\\\g(1) = -3(1) + 2\\\\g(1)=1[/tex]

Therefore, f(1) is greater than g(1).

E.) The value of the two functions when the value of x is 2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(2)=-(2-1)^2+9\\\\f(2)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(2) = -3(2) + 2\\\\g(2)=-4[/tex]

Therefore, f(2) is greater than g(2).

Thus, the two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).
