Mr. Stewart gives his students 3 straws that measure 10 inches, 12 inches and 18 inches. Ryan says that there is only one unique way to arrange the straws to form a triangle. Marcy says there are many ways to arrange the straws to form a triangle. Which student is correct? Explain.

Answers

Answer 1

Answer:

Marcy is correct

Step-by-step explanation:

If you had 3 straws that were the SAME length then there would only be 1 possible way to arrange them because no matter what order you put them in to form a triangle the outcome would always be the same because all 3 straws are the same length.

Since there are different lengths of straws, there are 3 possible ways you can arrange them so basically, there are multiple ways you can arrange the straws to make a triangle.

Marcy is correct.

Ryan is wrong.

Answers

Answer:

Step-by-step explanation:

*Perpendicular lines have negative reciprocals slopes*

First, find the slope-intercept form of 5x + 6y = -54:

5x + 6y = -54

-5x          -5x

6y = -5x - 54

/6         /6

y = [tex]-\frac{5}{6}x[/tex] - 9

y = mx + b

when the legs of a triangle are both 6 cm. what is the hypotenuse

Answers

Answer:

72

Step-by-step explanation:

to find the hypotenuse you need to do  (Hypotenuse)^2 = (Base)^2 + (Altitude)^2, which is the Pythagorean theorem (a^2+b^2=c^2)

if the bases are both 6, you need to do 6^2+6^2= hypotenuse
6*6+6*6=?
36+36=72

Answer:

r = 2 and n = 3

Step-by-step explanation:

9 = r + 3+ 4

9 = r + 7

r = 2

10 = n +2 + 5

10 = n + 7

n = 3

Answer:

r = 2 ft

n = 3 ft

area = 61 ft²

explanation:

total length : 10 fttotal width : 9 ft

-------------------------------

n + 2 + 5 = 10 n = 10 - 7n = 3 ft

-------------------------------

r + 3 + 4 = 9 r = 9 - 7r = 2 ft

Find the measure of each angle in Triangle ABC. m∠a=(50−x)°m∠b=(9x−40)°m∠c=90°

Answers

Answer:

40°

50°

90°

Step-by-step explanation:

sum of angle in a triangle is= 180°

(50-x)° + (9x-40)° + 90° = 180°

50-x+9x-40 + 90 = 180

50- 40 +90 -x+9x =180

100 + 8x = 180

8x = 180 -100

8x = 80

x = 80/8 =10

x = 10°

measure of a= (50-x) = 50- 10 = 40°

measure of b = (9x-40)= 90- 40= 50°

measure of c = 90°

During a sale, a store offered a 15% discount on a camera that originally sold for $600. After the sale, the discounted price of the camera was marked up by 15%. What was the price of the camera after the markup? Round to the nearest cent.

Answers

1. Find 15% off $600

(15*600)/100= 90
600-90=510

Discounted price is $510

2. Mark up by 15%

To mark it up you divide the percentage by 100 and then add 1 since the price is going up. If it was being marked down it would be 0.15.

510x1.15 = $586.5
Rounded up to $587

The final marked up price is $586.5

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: Discount %=15 Marked price=$600 and after the sale marked up percentage is 15%

Thus, Discounted price = 600×(1-15%)

                                        = 600× 0.85

                                         =$510

And therefore the marked up price after sale is= $510×(1+15%)

                                                                              = $586.5

Hence, The final marked up price is $586.5

Suppose the monthly charges for cell phone plans in the U. S. Are normally distributed with a mean of $62 and a standard deviation of $10. What is the proportion of cell phone plans charging less than $42 a month for service?

Answers

Using the normal distribution, it is found that 0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 62, \sigma = 10[/tex].

The proportion of cell phone plans charging less than $42 a month for service is the p-value of Z when X = 42, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{42 - 62}{10}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a p-value of 0.0228.

0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.
