16x - 8 can be 8(2x - 1)

The distributive property is used to generate this expression.

The distributive property states that multiplying the sum of additional addends by a number yields the same outcome as multiplies each addend separately by the number and combining the resulting products.

55ft²

Answer:

Solution given:

the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2

=base area *2 laternal faces area

=25+2*15=25+30=55ft²

Answer:

A

Step-by-step explanation:

V = (0.04)*H (Company P)

V = (0.06)*H (Company S)

V represents the vacation hours and H is the hours worked

If they both work 2080 hours

V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)

V2 = (0.06)*(2080) = 124.8 vacation hours (Company S)

124.8 - 83.2 = 41.6 hrs

Answer:

Step-by-step explanation:

angle 7 and 16 are vertical to each other.

Answer:

A

Step-by-step explanation:

A: -a/-b=c (negative number divided by negative number is positive number A is correct)

B: -a x b =c (negative number times positive number is become a negative number so correct answer is -c B is wrong)

C: -a/b=c (negative number divided by positive number is become a negative number so correct answer is -c C is wrong)

D: -a x -b=-c (negative number times negative number is become a positive number so correct answer is c D is also wrong)

Answer:

I think it's A.

Honestly, I'm not sure how to answer this, but I think this can help you.

Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.

(I think F is an answer)

Answer: ∠1 and ∠5

Step-by-step explanation:

You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

Hope this helps :)

Answer:

J all rational numbers are real numbers

Step-by-step explanation:

Let the number of visits equal x.

Multiply the number of points by the points per visit.

2.5x

Add that to the points he got for signing up:

2.5x + 35

This needs to equal the total points needed:

2.5x + 35 = 70

Solve for x:

Subtract 35 from both sides:

2.5x = 35

Divide both sides by 2.5:

X = 14

He needs 14 visits

Answer:

v = 628.32 m³

Step-by-step explanation:

v = πr²h/3

v = π(20/2)²(6)/3

v = π(100)(2)

v = 628.318530718

Rounded

v = 628.32 m³

Answer:

223.5 Km

Step-by-step explanation:

Area = Length x Width

Solving for Square Shape

8 · 6 = 48 km

Area = Length x Width

Solving for Rectangle Shape

9 · 14 = 126 km

Area = Length x Width ÷ 2

Solving for Triangle Shape

11 · 9 = 99 ÷ 2 = 49.5 Km

48 + 126 + 49.5 = 223.5 Km

Answer:

85 ft^2

Step-by-step explanation:

Ok, the square base area is 5 x 5 = 25 square feet

the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.

To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.

15 x 4 = 60 + 25 = 85 square feet

Answer:

Step-by-step explanation:

a quantity which during a calculation is assumed to vary or be capable of varying in value. or a quantity which during a calculation is assumed to vary or be capable of varying in value.

Answer:

We know the width maybe 22ft and at its widest.

IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.

With triangles;

The number of triangles is always 2 less than that that of its sides.

= 3 triangles + 2 = 5 sides.

The sum of interior angles

(n-2) x 180 = 540 degree

5-2 x 180

To determine the amount of sides; we remember

(n-2) 180

360 = (n-2) 180

+360 = 180 -360 +180

+360 = 180 = (3 triangles with 180)

900/180 = 5 sides.

If we say 5 triangles created with 3 given lengths

then same rule applies n-2 (180)

=7 sides

= if regular shape largest line 22 x 7 = 154 ft sq = Area.

Answer:

374

Step-by-step explanation:

First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374

Answer:

B) [tex]x=\sqrt{90}[/tex]

Step-by-step explanation:

Pythagorean thm formula:

a² + b² = c²

Given:

a = 9

b = 3

c = x

Work:

a² + b² = c²

9² + 3² = x²

81 + 9 = x²

90 = x²

[tex]\sqrt{x^2} =\sqrt{90} \\x=\sqrt{90}[/tex]

Answer:

b = 42° and c = 180-42 = 138°

Answer:

b) 42°

c) 138°

Step-by-step explanation:

Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.
