Answers

Answer 1

Answer:

Option C

Step-by-step explanation:

Area of the composite figure = Sum of the areas of three rectangles given

                                                = (3x)(x) + 4x + 3(3x)

                                                = 3x² + 4x + 9x

                                                = 3x² + 13x

Since, area of the figure = 82

Therefore, expression representing area of the figure is,

3x² + 13x = 82

Option (C) will be the answer.

Here, x is a variable.

And we can get the value of x by using quadratic formula.

Which of these expressions are equivalent to 4x+2(2x−5)−(3−5x) ? Choose the TWO correct answers.
a- 3x−13

b- 13x−13

c- 8x−5−3−5x

d- 8x−10−3−5x

e- 8x−10−3+5x

Answers

Answer:

4x+2(2x−5)−(3−5x) = 8x-10-3+5x

Step-by-step explanation:

We need to find the equivalent expression to 4x+2(2x−5)−(3−5x).

Using distributive property as follows :

a(b+c) = ab+ac

4x+2(2x−5)−(3−5x) = 4x+4x-10-3+5x

= 8x-10-3+5x

Option (e)

Hence, the correct option is (e) "8x-10-3+5x"

I think it's 36

Step-by-step explanation:

13.) An electrician has a piece of wire that is 3 feet long (36 inches). She needs a piece that is exactly 31.05 inches to fit perfectly in the outlet. How much wire will she have left over? *

O she needs to buy more baseboard, she doesn't have enough
O 4.95 inches
O 28.05 inches
O5.05 inches​

Answers

Answer:  4.95 inches

Subtract:  36 - 31.05 = 4.95

Step-by-step explanation:

Whoever created this question hasn't done much real electrical work!

An outlet (also known as a receptacle) usually requires about 4 to 6 inches of wire within the junction box to make the connections, depending on what else may be connected in the box. We don't have to measure to 0.05 of an inch. The insulation may have to be stripped precisely to 3/8, 1/2 or 5/8 inch for connections.  

The electrician used 3 feet of cable between junction boxes, and had 8 ¹/₂ inches pulled through the junction box. She needed 4 inches to connect the receptacle. How much the excess did she have to cut off?

69.08 cm

Explanation :

Given :

Radius of a circle = 11 cm

To Find :

Circumference of the circle = ?

Solution :

As, we have radius of the circle is 11 cm and to find circumferemce, we have a formula :

[tex] \large \underline{\boxed{\bf{Circumference = 2\pi r}}}[/tex]

By filling value of r = 11 cm and π = 3.14, we have :

[tex] \sf : \implies Circumference = 2 \times 3.14 \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = 2 \times \dfrac{314}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{628}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{6908}{100} \: cm[/tex]

[tex] \sf : \implies Circumference = 69.08\: cm[/tex]

Hence, circumference of the circle is 69.08 cm.

Use what you already know to find a, b, and c.
Input each value. Then click done. HELP ME PLEASE FAST!

Answers

Answer:

Use the "find vertically opposite angle" method.

a = 80°

To find the other angles:

Since the angles equal up to 360 which makes a full circle shape...

360 - 80 - 80 = 200 (B and C)

200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)

b = 100°

c = 100°

How can you write an equation of a line when you are given the slope and the y-intercept of the line? Explain

Answers

Answer:

The linear equation that represents each function is y=mx+b. While The m represent the slop so instead of writing you write the slope provided. Then multiply by the X + b which is your Y-intercept.

Here is an example,

The slope is 2/3 and the y intercept is 6, write a linear equation for this sequence.

y= (2/3). X +6
