**Answer:**

**As per the given statement**: A forest ranger wants to determine the radius of the trunk of a tree. She measures the circumference to be 8.6 feet.

Shape of the trunk of a tree is circle.

**Use the circumference formula:**

where C is the circumference of a circle and r is the radius of a circle.

**Solve for r;**

Given: C = 8.6 feet and use

Substitute the given value we get;

Simplify:

Divide both sides by 6.28 we get;

r = 1.6942675 feet

**Therefore, the trunk's radius to the nearest tenth foot is, 1.4 ft**

Question

What does nÃ·6 is??????

Solution 1

It equals n divided by 6 because there is not a given value for n.

Question

Determine the sum: (7j9k âˆ’ 3j2k3) + (âˆ’4j9k + 12j2k3). 3j9k + 9j2k3
7j22k8
3j18k2 + 9j4k6
4j9k + 8j2k3

Solution 1

The answer is

3j^9k+9j^2k^3

3j^9k+9j^2k^3

Question

Determine the sum: (14abc2 + 12a2b + 16b2c) + (âˆ’3abc2 + 2b2c). 11abc2 + 12a2b + 18b2c
11a2b2c4 + 12a2b + 18b4c2
41a4b7c6
42a3b4c3 âˆ’ ab3c3

Solution 1

The answer is 11abc^2 + 12a^2b + 18b^2c because:

14abc^2-3abc^2 is 11abc^2

12a^2b + 0 = 12a^2b

16b^2c +2b^2c = 18b^c

14abc^2-3abc^2 is 11abc^2

12a^2b + 0 = 12a^2b

16b^2c +2b^2c = 18b^c

Question

Determine the sum: (9r3s2t âˆ’ 4r2s2t2 âˆ’ 6rs2t3) + (âˆ’4r3s2t + 8rs2t3). 3r10s10t10
âˆ’r3s2t + 4rs2t3
5r6s4t2 âˆ’ 4r2s2t2 + 2r2s4t6
5r3s2t âˆ’ 4r2s2t2 + 2rs2t3

Solution 1

The answer is

5r3s2tâˆ’4r2s2t2+2rs2t3

5r3s2tâˆ’4r2s2t2+2rs2t3

Question

1.Wanda took out a personal loan for $5,000 at 9% simple interest. How much interest will she pay after 5 years? (SHOW YOUR WORK)
2.Suppose she pays off the loan in 1 years instead of 5 years. How much money will she save in interest? (SHOW YOUR WORK)

Solution 1

1.)Â First, you use the formula for finding the simple interest, which is I = Prt

I = PRT

I = 5,000 x 0.09 x 5

I = 450 x 5

I = $2,250

2.) Since it says 1 year instead of 5, you multiply 450 by 1. So she only pays $450. To get how much money she'll save in interest, you subtract 2,250 by 450, which equals 1,800. So, she'll save $1,800 in interest.

I = PRT

I = 5,000 x 0.09 x 5

I = 450 x 5

I = $2,250

2.) Since it says 1 year instead of 5, you multiply 450 by 1. So she only pays $450. To get how much money she'll save in interest, you subtract 2,250 by 450, which equals 1,800. So, she'll save $1,800 in interest.

Question

On a map with a scale of 2 cm = 1km, the distance from Beau's house to the beach is 4.6 centimeters. What is the actual distance?

Solution 1

So the given is 4.6 cm and you're trying to find the amount of km.

GIVEN: 2 cm = 1 km

4.6/2 = 2.3 km

GIVEN: 2 cm = 1 km

4.6/2 = 2.3 km

Solution 2

2.3

since 2 cm=1k you divide by 2

Question

Choose the correct simplification of the expression (7m3 n) 2. 14m5n3 14m6n2 49m5n3 49m6n2

Solution 1

For this case we have the following expression:

Â (7m ^ 3n) ^ 2

Â By power properties we can rewrite the expression as:

Â ((7 ^ 2) (m ^ (3 * 2)) (n ^ 2))

Â Then, simplifying we have:

Â (49 (m ^ 6) (n ^ 2))

Â**Answer:**

Â**the correct simplification of the expression is:**

Â**(49 (m ^ 6) (n ^ 2))**

Â (7m ^ 3n) ^ 2

Â By power properties we can rewrite the expression as:

Â ((7 ^ 2) (m ^ (3 * 2)) (n ^ 2))

Â Then, simplifying we have:

Â (49 (m ^ 6) (n ^ 2))

Question

The weather report says there is an 85% chance it will be very hot tomorrow. Should you get ready to use the air conditioner? Explain.

Solution 1

Yes because the probability rate is high.

Question

Mila wants to spend at least $20 on a classified ad in the newspaper. She has $12, how much does she need? I need an equation with an inequality please:) thank you!

Solution 1

X >= (at least symbol) $9 since she needs AT LEAST 20$ and she already has 12$ so 12+9>20

Question

Which expression gives the distance between the points (5, 1) and (9, -6)?

Solution 1

**Answer:**

**Step-by-step explanation:**

Let and be the two points.

We have to find the distance between the two points.

**The distance Formula:**

Here, we are given = (5,1) and Â Â = (9,-6)

Then, the **distance between these two points is given by:**

**Thus, the distance between the given point is .**

Solution 2

So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2

it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.

rad (9-5)^2 + ((-6)-1)^2

rad 4^2 + (-7)^2

rad 16 + 49

rad 65

it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.

rad (9-5)^2 + ((-6)-1)^2

rad 4^2 + (-7)^2

rad 16 + 49

rad 65
