Elena and Lin are training for a race. Elena runs her mile a constant speed of 7.5 miles per hour.
Lin’s times are recorded every minute:
time (minutes) 1 2 3 4 5 6 7 8 9
distance (miles) 0.11 0.21 0.32 0.41 0.53 0.62 0.73 0.85 1
1. Who finished their mile first?
2. This is a graph of Lin’s progress. Draw a graph to represent Elena’s mile on the same axes.
3. For these models, is distance a function of time? Is time a function of distance? Explain how you know.

Answer:

the answer is b

Step-by-step explanation:

Jackson gets 12 dollars an hour making that 12x and his pay is reduced by 14 so that would make it 12x(12 dollars an hour) - 14 (what's reduced). and if he has less than 198, b would be the only answer that works

Answer: Two terms

Step-by-step explanation: The expression 2 + n^2 has only two terms: a constant term 2 and a variable term n^2. So, there are two terms in this expression.

There are 3 terms in this expression yw :)

Answer: Rhombus

Step-by-step explanation:

Let's plot this into a graph.

A = (3,5)

B = (5,8)

C = (7,5)

D = (5,2)

As you can clearly see in the image below, the shape is a rhombus.

Do not get confused between rhombus and parallelogram.

In a rhombus, all the four sides are equal and the diagonals intersect at 90 degrees, whereas in a parallelogram, the opposite sides are equal and the diagonals bisect each other.

Answer:

3(5) + 3(6) + 3(7) + 2(1/2)(6)(5) =

Answer:

D would most likely be best

Step-by-step explanation:

Because its impossible for both of them to happen together

The probability of A and b together equals 0 - impossible

Answer:

Step-by-step explanation:

Answer:

90° clockwise rotation

Step-by-step explanation:

A horizontal translation would have left the shape pointing in the same direction.

A reflection across the y-axis would bring it to a quadrant that is not shown.

90 degree counterclockwise rotation would have again taken the shape to a quadrant that is not shown.

The other answer is also correct. Their reasoning may help you understand it better, because people learn in different ways. So, I encourage that you read that as well.

Answer:

4. Drawing 2 is a scale of Drawing 1

A) is 2.5

B) is 7.8

Step-by-step explanation:

13/5.2=2.5

5.2 x 2.5=13

And since we have the scale factor 2.5

and since it decreases in size we divide

19.5/2.5= 7.8

:D correct

Answer:

I think its angle LGB

Step-by-step explanation:

Angle LGB is adjacent to angle LGK.

Answer:

Angle BFC

Step-by-step explanation:

When an angle is complementary to another angle, that means they sum to 90 degrees.

Angle EFD is vertical to Angle AFC, so they are congruent. Because angle EFD is 90 degrees, and angle AFC is congruent, it is also 90 degrees.

So, we see, angle AFB + angle BFC = 90 degrees.

Angle BFC is complementary to AFB

It may seem confusing that it says 'select all that apply', and we only pick one answer, but trust the math. I have been on IXL myself, and have seen that even though it says 'select all that apply', there may only be one answer.

Hope this helps you! :)

Step-by-step explanation: 6^2-7(8+6-3^2)

36-7(8+6-9)

36-7 x 5

36-35=1

Answer:

1

Step-by-step explanation:

6² - 7 (8 + 6 - 3²)

Using BODMAS we'll have to solve what is in the bracket first.

= 6² - 7 (14 - 9)

= 6² - 7(5)

Multiply -7 by 5 still using the rule of BODMAS

= 6² - 35

= 36 - 35

= 1

Explanation:

Simplify the first expression: 1/2 to the power of 10

Add the two fully simplified exponents: 10+8=18

Answer to the question: 1/2 with the exponent of 18

Step-by-step explanation:

pi 2 is equal to 360 or a circle, and pi is equal to 180 so if it's between 3&4 make it 3&4 2 sooo

3×3=9 4×4=16 so pi2 is between 9&16

Answer: 45%

Step-by-step explanation:

(625.00 - 443.75) / 625=0.45

0.45 x 100 = 45

Answer: 1 5/28 or 33/28

Step-by-step explanation:

Ignore the addition sign because you have a negative, then find a common denominator: 28 then 4x7 is 28 multiply both sides of the fraction do that for both fractions then subtract the numerators and keep the denominator the same.

Answer:

1 5/28

Step-by-step explanation:

7/4 + -4/7

= 49/28 + - 16/28

= 33/28

= 1 5/28

Answer:

The perimeter of the rectangle is 84 cm.

Step-by-step explanation:

From X=-17 to X=8 is 25 cm.

From Y=12 to Y=-5 is 17 cm.

Therefore, the equation is 2(25) + 2(17) = 84

The perimeter of the rectangle is 84 cm.

We need to find the length and width of the rectangle first, and then use the formula for the perimeter, which is P = 2(l + w).

The length of the rectangle is the distance between the points (-17, 12) and (8, 12), which is 8 - (-17) = 25 units.

The width of the rectangle is the distance between the points (-17, 12) and (-17, -5), which is 12 - (-5) = 17 units.

Using the formula for the perimeter of a rectangle, we have:

P = 2(l + w) = 2(25 + 17) = 84 cm

Therefore, the perimeter of the rectangle is 84 cm.
