WILL GIVE 100 BRAINLY POINTS Instructions
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
Part 1: Writing Expressions: 25(10j + 18 + 5j)
Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
Translate the algebraic expression you created in Question 1 to a verbal expression.
Twenty five times the sum of ten j plus 3 plus j
Part 2: Writing Equivalent Expressions
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
Using commutative property of addition, the expression in question 1 can be rewritten as follows:
25(10j + 18 + 5j) = 25(10j + 5j + 18)

Using distributive property of multiplication over addition, the expression in question 1 can also be rewritten as follows:
25(10j + 18 + 5j) = 250j + 450 + 125j



Use either the commutative property or combine like terms to create an equivalent expression.
Use the distributive property to create an equivalent expression.
Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?
Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

Nick spent 34 minutes on the phone while routing 17 phone calls. In all, how many phone calls does Nick have to route to spend a total of 50 minutes on the phone? Assume the relationship is directly proportional.

Answers

Answer:

25 phone calls

Step-by-step explanation:

Create a proportion where x is the number of phone calls for 50 minutes on the phone:

[tex]\frac{34}{17}[/tex] = [tex]\frac{50}{x}[/tex]

Cross multiply and solve for x:

34x = 850

x = 25

An object is dropped from a height of 150 feet. Its heights s at time, t is given by the

equation s(t) =-16t^2+150 ,where s is measured in feet and t is measured in seconds.

Find the average rate of change of the height over the interval [1, 2.5).

O 1) -56 ft/sec

O2) 77 ft/sec

03) 56 ft/sec

O4) -35 ft/sec

Answers

Answer:

The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.

Step-by-step explanation:

Let [tex]s(t) = -16\cdot t^{2} + 150[/tex]. Geometrically speaking, average rate of change over a given interval ([tex]\bar v[/tex]), measured in feet per second, is determined by definition of secant line, which is defined:

[tex]\bar v = \frac{s(t_{2})-s(t_{1}) }{t_{2}-t_{1}}[/tex] (1)

Where:

[tex]s(t_{1})[/tex], [tex]s(t_{2})[/tex] - Initial and final position of the object, measured in feet.

[tex]t_{1}[/tex], [tex]t_{2}[/tex] - Initial and final times, measured in seconds.

If we know that [tex]t_{1} = 1\,s[/tex] and [tex]t_{2} = 2.5\,s[/tex], then the average rate of change over the interval [tex][1,2.5][/tex]:

[tex]s(1) = -16\cdot (1)^{2}+150[/tex]

[tex]s(1) = 134[/tex]

[tex]s(2.5) = -16\cdot (2.5)^{2}+150[/tex]

[tex]s(2.5) = 50[/tex]

[tex]\bar v = \frac{50\,ft-134\,ft}{2.5\,s-1\,s}[/tex]

[tex]\bar v = -56\,\frac{ft}{s}[/tex]

The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.

Hi there!

Difference:

[tex]\frac{7}{8}[/tex]

1.Convert each fraction terms into a similar denominator:

[tex]1\frac{1}{4}=1\frac{2}{8}[/tex]

[tex]\frac{3}{8}=\frac{3}{8}[/tex]

2.Simplify term into mixed numbers:

[tex]1\frac{2}{8}=8+2=10:\frac{10}{8}=\frac{5}{4}[/tex]

3.Subtract the terms:

[tex]\frac{10}{8}-\frac{3}{8}=\frac{7}{8}[/tex]

Therefore, the difference in length between 1 1/4 and 3/8 is 7/8...

A right triangle is shown. One leg is labeled 5 and the other is labeled 13. A right angles is labeled in between the legs.

Mckenzie's Work Cara's Work

a2 + b2 = c2 a2 + b2 = c2

52 + 132 = c2 52 + b2 = 132

25 + 169 = c2 25 + b2 = 169

194 = c2 b2 = 144

Square root 194 equals square root c squared. Square root b squared equals square root 144.

13.93 ≈ c b ≈ 12
Who is right?

Answers

Answer:

Makenzie is correct,  13.93 ≈c

Step-by-step explanation:

the sides with determined lengths (see image) are A (13) and B (5). C however is not determined.

the correct equation would be to solve for c.

13² + 5² = c²

[tex]\sqrt {169 + 25} = c[/tex]

c ≈ 13.93

Clara solved for b and not c, which is incorrect.

The right working is as follows:

c² = a² + b²

c² = 5² + 13²

Using Pythagoras theorem,

c² = a² + b²

where

c = hypotenuse

a and b are the other two legs.

Therefore,

c = ?

a = 5

b = 13

c² = 5² + 13²

c² = 25 + 169

c² = 194

c = √194

c = 13.9283882772

c = 13.9 inches

you and a friend fill balloons with water. Two out of every 25 balloons pop while being fillied what percent of the balloons do not pop while they are being fillied

Answers

Answer:

92 percent

Step-by-step explanation:

Answer:

92% of balloons filled did not pop.

Step-by-step explanation:

2 / 25 balloons is the fraction of balloons that do pop, and we want the percentage that don't pop.

To start off with, we will get the fraction of balloons that don't pop - 23 / 25.

We will then convert this fraction to a decimal by dividing the fraction:

23 divided by 25 = 0.92

Now, to convert this to a percentage, we just multiply by 100.

0.92 x 100 = 92%

Therefore the answer is 92% of balloons filled did not pop.
