form?
A. 0.000000094 kg
B. 0.0000094 kg
C. 0.000094 kg
D. 0.00094 kg

Answers

Answer 1
The mass in standard form is D. 0.00094 kg because the -4 in 10^-4 means that the decimal will me moved over to the left 4 times. Which you will have to add three zeros behind the decimal point.

Use the figure to find a+b+d + e
A. 330°
B. 325°
C. 290°
D. 300°

Answers

[tex]a + b + 35 + d + e = 360[/tex]

Subtract the sides of the equation minus 35

[tex]a + b + d + e = 360 - 35[/tex]

[tex]a + b + d + e = 325[/tex]

So the correct answer is : (( B. 325° ))

How many feet does a wheel with a diameter of 12 inches travel after two revolutions

Answers

Using the circumference formula we know that the wheel of a diameter 12 in will cover 6.26 ft.

What is the Circumference of the circle?

The circumference of a circle or ellipse in geometry is its perimeter.

That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.

The curve length around any closed figure is more often referred to as the perimeter.

Now, we know that the radius is 12/2 = 6 in.

Then circumference will be:

= 2πr

= 2π6

= 37.6

= 37.6 * 2

= 75.2 in

We know that:
1 inch = 0.083 ft

75.2 inch = 6.26 ft

Therefore, using the circumference formula we know that the wheel of the diameter 12 in will cover 6.26 ft.

Answers

Answer:

None of the options are correct, the correct answer is 1,050 boys and 350 girls.

Step-by-step explanation:

A ratio of 3:4 can be turned into a percentage by dividing 3 by 4. This would give us 0.75 or 75%. This means that the remaining 25% (100-75 = 25) are girls in this ratio. If there are 12 boys we can find the total amount by dividing 12 by 0.75 and then multiplying that answer by 0.25 (25%) in order to find the amount of girls in that ratio, like so...

12 * 0.75 = 16 total

16 * 0.25 = 4 girls

If there are a total of 1,400 students we can find how many are boys and how many are girls by simply multiplying by the percentages.

1,400 * 0.75 = 1,050 boys

1,400 * 0.25 = 350 girls.

Apparently, none of the options are correct, the correct answer is 1,050 boys and 350 girls.

SHOE COLLECTION: Marquise, Bron'Tavious, and JayDarius each have a shoe collection of Nike Air Vapor Max shoes. Marquise has two times as many pairs of shoes than Bron'Tavious and JayDarius have fifteen more pairs of shoes than Bron'Tavious. All together they have ninety-five pairs of shoes. (a) How many pairs of shoes Marquis have? (b) How many pairs of shoes does Bron'Tavious have? (c) How many pairs of shoes does JayDarius have? Provide evidence and how you got your answer.​

Answers

Answer:

(a) The number of shoes that Marquise has is 40 pairs of shoes

(b) The number of pairs of shoes that Bron'Tavious has is 20 pairs of shoes

(c) The number of pairs of shoes that JayDarius has is 35 pairs of shoes

Step-by-step explanation:

The given information are;

The number of shoes that Marquise has = 2 × The number of pairs of shoes that Bron'Tavious

The number of pairs of shoes that JayDarius has = The number of pairs of shoes that Bron'Tavious + 15

The total number of pairs of shoes they have all together = 95 pairs of shoes

Let the number of pairs of shoes that Bron'Tavious has = X. Therefore, we have;

The number of shoes that Marquise has = 2 × X

The number of pairs of shoes that JayDarius has = X + 15

The total number of pairs of shoes they have all together = X + X + 15 + 2 × X = 95

X + X + 15 + 2 × X = 95

4 × X + 15 = 95

4 × X = 95 - 15 = 80

X = 80/4 = 20

∴ X = 20

(a) The number of shoes that Marquise has = 2 × X = 2 × 20 = 40

The number of shoes that Marquise has = 40 pairs of shoes

(b) The number of pairs of shoes that Bron'Tavious has = X = 20

The number of pairs of shoes that Bron'Tavious has = 20 pairs of shoes

(c) The number of pairs of shoes that JayDarius has = X + 15 = 20 + 15 = 35

The number of pairs of shoes that JayDarius has = 35 pairs of shoes.
