Answer:

(f o g)(4)=27

Step-by-step explanation:

(f o g)(4)=2x+5

f(g(4))=2x+5

f(4²-2(4)+3)=2x+5

f(16-8+3)=2x+5

f(8+3)=2x+5

f(11)=2x+5

f(11)=2(11)+5

f(11)=22+5

f(11)=27

Therefore, (f o g)(4)=27

2) Since a cube has all equal sides, then our equation would be V = 1.5³

3) V = 1.5³ = 3.375 in³

Answer:

3.375 in^3.

What is the area of this composite figure??

Please help! I am so confused!

Answers

Answer:

180 cm²

Step-by-step explanation:

Area of Triangle: 1/2bh

You can divide the figure into two parts: top and bottom.

Top:

1/2(4)(12)

1/2 (48)

24 • 2 (two triangles) = 48 cm²

Bottom:

1/2(12)(11)

1/2 (132)

66 • 2 (two triangles) = 132 cm²

Add them up: 48 cm² + 132 cm² = 180 cm²

Mirela has a rectangular piece of paper with an area of 0.35 m2. She cuts the paper into small rectangles with areas of 700 cm2. What is the maximum number of rectangles she can cut?

Answers

Answer:

The maximum number of rectangles that Mirela can cut is 5

Step-by-step explanation:

First, you must ensure that all the measurements are the same units.

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

where a, b and c are known values and x the value to calculate. So:

[tex]x=\frac{c* b}{a}[/tex]

The direct rule of three is the rule applied in this case where there is a change of units.

To perform this conversion of units, you must first know that 1 m² = 10,000 cm². So, if 10,000 cm² is 1 m², how many cm² equals 0.35 m²?

[tex]cm^{2} =\frac{0.35 m^{2} *10000 cm^{2} }{1 m^{2} }[/tex]

cm²= 3500

Now, to calculate the maximum number of rectangles that Mirela can cut you divide the total area of the paper by the area of each rectangle:

3500 cm² ÷ 700 cm²= 5

The maximum number of rectangles that Mirela can cut is 5

Write an equation and solve for x.

Answers

Answer:

x = 22

Step-by-step explanation:

All the sides are equal. So, it is and equilateral triangle and so all the angles will be equal.

Each angle of equilateral angle = 180/3 = 60

3x - 6 = 60 {Add 6 to both sides}

3x = 60 +6

3x = 66 {Divide both sides by 3}

x = 66/3

x = 22

Answers

180 are empty
............

Answer:

120 seats

Step-by-step explanation:

Total seats in the hall = 300

Percentage of filled seats = 60 %

Number of seats filled = (60 / 100) 300

= 60 * 3

= 180

Therefore, number of empty seats = 300 - 180

= 120

Step-by-step explanation:

Original equation:

Subtract 9 from both sides

The equation should look like this now:

-3 > 3p

Divide both sides by 3 (to separate the 3 from the p)

Find g(-4) if g(x) = 8x^2 + 4x

Answers

Answer:

Your answer would be -144

The value of the function g(x) = 8x² + 4x at g(-4) is 112.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, a function g(x) = 8x² + 4x.

Now to obtain the value of g(-4) we'll simply substitute - 4 in place of x.

which is g(-4) = 8(-4)² + 4(-4).

g(-4) = 8×16 - 16.

g(-4) = 128 - 16.

g(-4) = 112.
