What is 18+6x=41+4x,x

Answers

Answer 1

Answer:

Answer:

x=11.5

Step-by-step explanation:

18+6x=41+4x

Subtract 4x from each side

18+6x-4x=41+4x-4x

18+2x = 41

Subtract 18 from each side

18-18 +2x = 41-18

2x =23

2x/2 = 23/2

x =11.5

The diameter of the jar of marshmallow fluff is 5in. What is the area of the jar opening? Please show the steps how to do that.

Answers

The opening of the jar is a circle.

The area of any circle is (pi) x (radius)²

What's the radius of the jar ?
Well, the diameter is 5 inches.
Radius = 1/2 of the diameter = 2.5 inches.

So Area = (pi) x (2.5 inches)² =

(3.14) x (6.25 square inches) = 19.625 square inches.

Final answer:

The area of the jar opening, being a circle, is found by using the formula A = pi*r^2. With a diameter of 5, the radius is 2.5. So the area is approximately 3.14 * 2.5^2 = 19.625 square inches.

Explanation:

To calculate the area of the jar opening, which is a circle, you need to know the radius of the circle. The given information is that the diameter is 5 inches. The radius is half the diameter, therefore, in this case, the radius is 5/2 = 2.5 inches. Then to find the area, you use the formula for the area of a circle: A = pi * r^2, where pi is approximately 3.14 and r denotes the radius. Substituting the known values into the formula, we have Area = 3.14 * (2.5^2) = 3.14 * 6.25 = 19.625 square inches. Thus, the area of the jar opening is approximately 19.625 square inches.

Gordy is a goalie for a neighborhood soccer team.He played in 65% of the 20 games this season.In how man ygames did he not play? ExplainA.6
B.7
C.10
D.13

Answers

If you would like to know in how many games Gordy didn't play, you can calculate this using the following steps:

Gordy played in:
65% of 20 games = 65% * 20 = 65/100 * 20 = 13 games

He did not play in:
20 games - 13 games = 7 games

The correct result would be B. 7 games.

.35*20=7

B.7 is the answer.

A large truck is going down a hill at 60 miles per hour. The driver needs to begin slowing down by shifting the gears. The speed goes down by 10 miles per hour each time he downshifts. Which expression shows his speed after three shifts?60 + (3 × 10)

60 – (-10 × 3)

60 – 10

60 + (-10 × 3)

Answers

It would be D. 69 + ( - 10 x 3 ). Because here are the keywords. He was going DOWN (negative) at a hill. And he now needs to SLOW DOWN (negative) by shifting the gears. Then he speeds DOWN (negative) 10 miles PER hour. And it says, how much speed after 3 shifts.

What is 1/3 added to 5/6

Answers

7/6
Change 1/3 to 2/6 in order to have a common denominator.
Then add the numerators (2 and 5) and keep the denominator.

The first thing to do is to make the denominators. Since 3 goes into 6, the first fraction should simply be doubled:
1/3 + 5/6 = 2/6 + 5/6
5 + 2 = 7
7/6

1/3 + 5/6 = 1 1/6 or 7/6

What is the surface area of this prism? A. 120 cm2 B. 122 cm2 C. 240 cm2 D. 184 cm2

Answers

Here is how to get the Surface Area of a triangular prism.
First you must find their areas first then multiply it by 2 (because it has 2 faces) except for the base, since it has a triangular base.
A = bxh/2   A = 15 m x 30 m A = 30 m x 18 m
   = (18 m x 12 m )/2 = 450 m^2 = 540 m^2
   = 216 m ^2/2
   = 108 m^2
Add all the faces:
SA = 2 (108 m^2) + 2 (540 m^2 ) +  450 m^2
= 216 m^2 +1080 m^2 + 450 m^2
= 1,746 m^2
The answer is not found in your choices. The attached picture is also showing m (meter) as the unit used not cm.....so I guess you got the wrong choices.
