Answer:

5/-1

Step-by-step explanation:

The two points are (-1, -2) and (-2, 3).

Slope is y change over x change.

So... 3-(-2) over -2-(-1).

That is 5 over -1.

Slope is 5/-1.

Answer:

Step-by-step explanation:

Use the Law of Cosines to find the measure of angle A from the lengths of the sides.

A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°

B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°

C = 180 - A - B = 95.3°

Answer:

[tex]y = 2x +3[/tex]

Step-by-step explanation:

Given

Parallel: [tex]y = 2x + 5[/tex]

Passes through (1,5)

Required

Determine the equation

Because it is a parallel to [tex]y = 2x + 5[/tex] then they have the slope.

The slope of [tex]y = 2x + 5[/tex] is 2 i.e. from [tex]y = mx + b[/tex]

So:

[tex]m = 2[/tex]

The line equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 2(x - 1) + 5[/tex]

[tex]y = 2x - 2 + 5[/tex]

[tex]y = 2x +3[/tex]

Answer:

Yes, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.

Step-by-step explanation:

For the given vessel without a lid,

diameter = 0.4 x 1.5

               = 0.6 m

radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{0.6}{2}[/tex]

           = 0.3 m

Total external surface area of the vessel = 2[tex]\pi[/tex]rh + [tex]\pi[/tex][tex]r^{2}[/tex]

                             = [2 x [tex]\frac{22}{7}[/tex] x 0.3 x 1.5] + [[tex]\frac{22}{7}[/tex] x [tex](0.3)^{2}[/tex]]

                             = 2.8286 + 0.2829

                             = 3.1112

Total external surface area of the vessel is 3.1112 square meter.

Total internal and external surface area = 2 x 3.1112

                                                              = 6.2224 [tex]m^{2}[/tex]

But for 1 square meter, 150 g of paint is consumed. Thus;

for 6.2224 [tex]m^{2}[/tex] = 6.2224 x 150 g

                       = 933.36 g

Thus, 6.2224 [tex]m^{2}[/tex] of area would require 933.36 g of paint.

So that,

[tex]\frac{933.36}{1000}[/tex] = 0.93336 kg

Therefore, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.

Step-by-step explanation:

Answer:

choices 1, 3, & 4 are true, 2 is not

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

Given that ∆ABC ~ ∆AGF, it follows that their lengths would be proportional to each other. This implies that:

AB/AG = AC/A F

Substitute

55/22 = 30/(4x - 4)

5/2 = 30/(4x - 4)

Cross multiply

5(4x - 4) = 30(2)

20x - 20 = 60

20x - 20 + 20 = 60 + 20

20x = 80

Divide both sides by 20

20x/20 = 80/20

x = 4

The area of the composite figure is A = 369.75 cm²

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be A

where A = A₁ + A₂

Now , area of first rectangle A₁ = 10.5 x 15.5

A₁ = 162.75 cm²

And , area of second rectangle A₂ = 18 x 11.5

A₂ = 207 cm²

So , A = 162.75 cm² + 207 cm²

A = 369.75 cm²

Hence , the area of figure is A = 369.75 cm²

Given:

Two numbers are 12 and 21

To find:

The factors of 12 and 21, then find the common factor and the greatest common factor.

Solution:

Two numbers are 12 and 21. The prime factors of these two numbers are

[tex]12=2\times 2\times 3[/tex]

[tex]21=3\times 7[/tex]

From the above factorization, it is clear that the factor 3 is common in both. So,

Common factor (CF) = 3

Only 3 is common in factorization of both. So,

Greatest common factor (GCF) = 3

Therefore, the common factor is 3 and the greatest common factor is also 3.

Answer:

The answer is x > 32.

Step-by-step explanation:

1) Subtract 12 from both sides.

[tex] \frac{x}{4} > 20 - 12[/tex]

2) Simplify 20 - 12 to 8.

[tex] \frac{x}{4} > 8[/tex]

3) Multiply both sides by 4.

[tex]x > 8 \times 4[/tex]

4) Simplify 8 × 4 to 32.

[tex]x > 32[/tex]

Therefor, the answer is x > 32.

Answer:

1, 0 or 1, 1/2

Step-by-step explanation:

[tex]\frac{1}{2} = \frac{2}{4}[/tex]

2 goes into 3 once

and doesn't fit into 1

So, [tex]\frac{2}{4}[/tex] goes into [tex]\frac{3}{4}[/tex] once

and it doesn't go into [tex]\frac{1}{4}[/tex]

It could also be 1, 1/2

because half of two can fit into 1

so half of [tex]\frac{2}{4}[/tex] can go into [tex]\frac{1}{4}[/tex]
