Can someone pleseeeee help me I beg you and please show your work

Answer:

Step-by-step explanation:

11)

A= (B x H)/2

A= (2.9x3.2)/2= 4.64cm²

12)

A= (B+b)H /2

A= (12+10)5.6 /2 = 61.6in

Answer:

I think that the answer might be 9.30 for the first one and the second one I think is 670.

Step-by-step explanation:

To find the area, you have to multiply the height and width for the two figures.

3.2 × 2.9 = 9.28

12 × 10 × 5.6 = 672

I think you round those to the nearest tenth. 9.28 would be 9.30 and 672 would be 670. I hope this answers your question.

Answer:

B (the second one)

Step-by-step explanation:

The thin yellow line in A only goes from 14-30. However, the correct numbers listed range from 12-30. Line B matches up with this data

Answer:

2 because it holds the same value as -2 and its the additive inverse

Answer:

AB = 10 m

Step-by-step explanation:

Given that <ACB = <ECD, then triangles ABC and EDC are similar.

Let the height of the solar panel (AB) be represented by x. Thus by comparing the triangles, we have;

[tex]\frac{x}{6}[/tex] = [tex]\frac{45}{75}[/tex]

45x = 6 x 75

45x = 450

x = [tex]\frac{450}{45}[/tex]

x = 10

The height of the solar panel is determined to be 10 m.

Answer:

x = 4

Step-by-step explanation:

1. Write the equation

3/4x = 2x - 5

2. Get the variables on the same side

Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!

-1.25x = -5

3. Divide both sides by -1.25

x = 4

Thank you for the points!!!

Answer:

The slope is 2

The y-intercept is 3

The equation is y = 2x +3

Step-by-step explanation:

The equation goes up 2 squares and over 1 square. 2/1 = 2

For y-intercept, look at the y-axis

The equation is supposed to be written as y = mx + b

m being the slope and b being the y-intercept.

Answer:

the greatest common factor is 3

Answer: The two numbers are 10 and 12.

Step-by-step explanation:

Let the two consecutive numbers are x and x +2.

As per given, we have

[tex](x+2)+3x=42\\\\\Rightarrow\ 4x+2=42\\\\\Rightarrow\ 4x=40\\\\\Rightarrow\ x=10[/tex]

Smaller number = 10

Larger number = 10+2=12

Therefore, The two numbers are 10 and 12.

Answer:

1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%

2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different

3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side

Step-by-step explanation:

Answer:

2π + 24 m² = 30.3 m²(3 s.f.)

Step-by-step explanation:

Area of rectangle: l x w

6 x 4 = 24 m²

Area of semicircle: πr²/2

r = 4/2 = 2

π x 2² / 2

4π / 2

2π

Total area: 2π + 24 m² = 30.3 (3 s.f.)

Answer:

$20

Step-by-step explanation:

Kenny's gameplay: 1 month

Angie's gameplay: 3 months

1+3= 4

Kenny bought 1 software pack

Angie bought 2 software packs

1+2= 3

Each software package= $30

So 30×3= 90

Total cost= $170

170-90= 80

80÷4= $20

There you go :)

Answer:

Step-by-step explanation:

The eight in 6,084 is in the tenths place. Separately, it would be 80. The 8 in 9,821 is in the hundredths place. This one is worth 800. So the 8 in 9,821 is greater than the 8 in 6,084.
