Answer:

d = 200m

1400 m.

Step-by-step explanation:

This is direct variation.

At time 0 distance  run is zero.

d = km where d = distance, m = time and k is a constant.

k = the slope of the line joining the points and is  

800 / 4

= 200.

So the equation is d= 200m.

After 7 minutes he has run 20*7

= 1400 meters.

Answer:

  (C)  Step 1: 15x − 20 = 1; Step 2: 15x = 21

Step-by-step explanation:

The first step is to eliminate the parentheses, using the distributive property.

  5(3x − 4) = 1

  15x -20 = 1

The second step is to add 20 to both sides of the equation.

  15x = 21

This pair of steps is shown in the 3rd choice.

Comment on the answers

The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.

Answer:

7/100 or Decimal: 0.07

Step-by-step explanation:

The product of 70 multiplied by 10 to the power of -3 is 0.07

Given that product of 70 multiplied by [tex]10^{-3}[/tex].

Scientific notation is a way to express numbers that are very large or very small in a more concise and convenient form. It is commonly used in scientific and mathematical calculations, as well as in representing values in various fields such as astronomy, physics, and chemistry.

To solve this, we can use the concept of scientific notation. When a number is expressed in scientific notation, the exponent indicates the power of 10 by which the number should be multiplied.

In this case,  [tex]10^{-3}[/tex] means move the decimal point three places to the left.

Starting with 70, move the decimal point three places to the left to obtain 0.07. Therefore, the solution to 70 multiplied by [tex]10^{-3}[/tex] is 0.07.

Therefore, the product of 70 multiplied by  [tex]10^{-3}[/tex] is 0.07.

The length of the segment GI is 30.5 units

Step-by-step explanation:

In any triangle, the line segment joining the mid-points of two sides is parallel to the third side and equal to half its length

In ΔFHJ

∵ G is the mid-point of the side FH

∵ I is the mid-point of the side JH

∵ FJ is the 3rd side of the triangle

→ From the rule above

GI // FJ

GI = [tex]\frac{1}{2}[/tex] FJ

∵ FJ = 61 units

∴ GI = [tex]\frac{1}{2}[/tex] (61)

GI = 30.5

The length of the segment GI is 30.5 units
