Jana and Jenn are training to run a race. Jana runs 3 miles in 1/3 hour. Jenn runs 5 miles in 3/4 hour. Who runs faster, and what is the unit rate of her speed in minutes per mile?

**Answer:**

*Jenn runs faster at 9 minutes/mile.*

**Step-by-step explanation:**

Jana runs 3 miles in 1/3 hour.

1/3 hour is equivalent to 1/3*60 = 20 minutes

The ratio time/distance is the reciprocal of the speed and is greater as the speed is lower and vice-versa.

This ratio for Jana is 20/3=16.7 minutes/mile

As for Jenn, she runs 5 miles in 3/4 hour.

3/4 hour is equivalent to 3/4*60=45 minutes

The ratio time/distance is 45/5=9 minutes/mile

Since Jenn has a lower ration, her speed is greater than Jana's, thus **Jenn runs faster.**

What is the perimeter, in units, of polygon EFGHJK?

**Answer:**

38 units.

**Step-by-step explanation:**

**Perimeter** of the polygon EFGHJK = 38 unit

**Perimeter** of a shape is defined as the total **length** of its **boundary**. The perimeter of a shape is determined by **adding** the length of all the **sides** and edges enclosing the shape. It is **measured** in **linear** units of measurement like centimeters, meters, inches, or feet.

Given,

In graph of polygon EFGHJK

EF = 2 unit

FG = 10 unit

GH = 9 unit

HJ = 8 unit

JK = 7 unit

KE = 2 unit

**Perimeter** of EFGHJK = EF + FG + GH + HJ + JK + KE

= 2 + 10 + 9 + 8 + 7 + 2

= 38 unit

Hence, 38 unit is the measure of **perimeter** of polygon EFGHJK.

Find the equation for a line in slope-intercept form that goes through the points (-3, -2) and (3, 16)

Answer:

y = 3x+7

Step-by-step explanation:

The standard form of equation in slope-intercept form is:

y = mx+c

m is the slope

c is the intercept

Given the coordinates (-3, -2) and (3, 16)

Get the slope;

Slope = ∆y/∆x

Slope = y2-y1/x2-x1

Slope = 16-(-2)/3-(-3)

Slope = 16+2/3+3

Slope = 18/6

Slope = 3

Get the Intercept

Substitute one of the points in the formula:

Using the coordinate (-3, -2)

y = mx+c

-2 = 3(-3)+c

-2 = -9 + C

c = -2+9

c = 7

Get the equation of the line by substituting m and c into the equation y = mx+c

y = 3x+7

. Perpendicular lines have negative reciprocal slopes, so if the slope of one is x, the slope of the other is

.

The negative reciprocal of

is equal to −2, therefore, −2 is the slope of our line.

Since the equation of line passing through the midpoint (1,6), therefore, substitute the given point in the equation y=−2x+b:

6=(−2×1)+b

6=−2+b

b=6+2=8

Substitute this value for b in the equation y=−2x+b:

y=−2x+8

Hence, the equation of the line is y=−2x+8.

A die is rolled. The set of equally likely outcomes is (1, 2, 3, 4, 5, 6). Find the probability of getting a 3.

Answer:

Step-by-step explanation:

1/6

The **probability** of getting 3 is 1/6.

**Probability **is defined as the **possibility **of an event to be happened which is the **ratio **of no. of **favorable outcomes **and total no.** **of **outcomes**.

**Probability **of an event = P(E) = No. of** favorable outcomes**/Total No. of **outcomes**

Here given that the dice are fair and six-sided is rolled.

Total no. of **outcomes **by rolling the dice = 6 i.e. {1,2,3,4,5,6}

The **event **is to get the **number **3 by rolling the dice.

The **favorable outcome** is = {3}

**Number **of **favourable outcomes**= 1 i.e. {3}

As the dice is the set of equally likely **outcomes**.

**Probability **of getting 3 = P(getting 3)= No. of favorable **outcomes**/Total No. of **outcomes**= 1/6

Therefore the **probability **of getting 3 is 1/6.

**Answer: x=18**

im assuming that this is a right angle

so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.

**Answer:**

m = -3

**Step-by-step explanation:**

First, find two clear points:

** (1, -2) (0, 1)**

Then, use the slope formula:

**m = ****y2 - y1**

** x2 - x1**

**m = ****1 - (-2)**

** 0 - 1**

** = ****3** **= -3**

** -1**

**m = -3**

This means that the rise-over-run is -3 over 1, or 3 over -1.

Which means three down and 1 to the right, or 3 up and 1 to the left.

**Slope is the steepness of the line.**
