Jaylah started with $200 in her savings account to go to Disneyland. She wanted to increase her savings so she started babysitting. She earns $10 an hour and deposits it in her savings account. What is Jaylah's initial value and rate of change?

Answers

Answer:

Initial Value= $200, Rate of Change= $10 per hour (or just $10)

Step-by-step explanation:

The initial value is what Jaylah started with, and in this case, she starts with $200.

The rate of change is how much Jaylah earns, in this case per hour. It says that she earns $10 an hour, so the rate of change is $10.

The common dominator of 6 and 10 is 2 because 2 is the only number that can fit inside 6 and 10. Hope this helps.

Answer:

3/10 is greater. and the bottom part is 30

Step-by-step explanation:

because 1/6= 0.2 and 3/10=0.3.

0.2>0.3 therefore 3/10 is greater.

and to find the common denominator you just have to list out the number of  and 10.

as you can see 30 is the common denominator.

Factor the expression using the GCF.

4m+32

Answers

hello!

In order to factor this expression, we should divide both terms of this binomial (a polynomial with 2 terms) by 4 (the greatest common factor)

Note:- We usually factor out the Greatest Common Factor, or the GCF.

Divide:-

m

8

Add the terms:-

m+8

Put parentheses around them:-

(m+8)

Put 4 outside the parentheses:-

4(m+8)

notes:-

If you wonder whether or not you've factored correctly, you can use the distributive property & distribute :)

4 = 1,2,4
32 = 1,2,4,6,8,16,32
We can see that the gcf is 4
divide 4m by 4 which is m
divide 32 by 4 which is 8
which will come out to be 4(m+8)
hope this helps.

Answers

Answer:

40

Step-by-step explanation:

Two ways we can solve this problem:

1. Graphically

2. Mathematically

Because you already solved it graphically, I will show you how to do so mathematically. Of course, graphically is much much easier and more efficient in this problem.

Let's break the problem down.

First, we are given a graph which contains a slope.

To find slope, we use the technique -> rise/run

Picking 2 obvious points from the graph, we can see

1st point -> (10, 20)

2nd point -> (40, 80)

Now, let's find the slope

[tex]\frac{80-20}{40-10} = \frac{60}{30} = 2[/tex]

Now, we have an equation y = 2x, where y = number of pies and x = cups of sugar

We want to find how many cups of sugar we need to bake 80 pies. Simply substitute 80 = number of pies = y

y = 2x -> 80 = 2x

Solving for x, divide both sides by 2

40 = x

We need 40 cups of sugar.

A triangle has one side that is 4 centimeters long and one that is 9 centimeters long. The third side is a whole number of centimeters. What is the longest possible third side?

Answers

Answer:

  12 cm

Step-by-step explanation:

You want the longest possible integer length of the third side of a triangle with sides 4 cm and 9 cm.

Triangle inequality

The triangle inequality requires the longest side be less than the sum of the other two sides:

  x < 9 cm + 4 cm

  x < 13 cm

The largest integer length less than 13 cm is 12 cm.

The longest possible third side is 12 cm.

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+75,000 . What is the difference in the populations of the cities when t=4 ?

Answers

Answer:

The difference in the populations of the cities when t=4 is 25,800.

Step-by-step explanation:

Given equations each of the city:

-150t+50,000

and

50t+75,000

To find the difference between the population when t=4, we first have to solve both equation when t=4.

For both equations, substitute 4 into t:

-150(4) + 50,000 = 49,400

50(4) + 75,000 = 75,200

Now subtract 49,400 from 75,200 and you get 25,800.

The difference in the populations of the cities when t=4 is 25,800.

50t+34 t=4 is accelerating

What are the first two steps of drawing a triangle that has all side lengths equal to 12 centimeters?
Select from the drop-down menus to correctly complete the statements.

Draw a segment (6, 12, 24) centimeters long. Then from one endpoint, draw a (30, 60, 90) ° angle.

Answers

Answer:

All the sides should be 4 cm.

Step-by-step explanation:

The first triangle rule is the two sides should be greater than the longest side when added together.

For example- 4+4=8 which is bigger than 4

12 divided by 3 is 4.

Hope this helps.

Answer:

Step-by-step explanation:

Remark

All triangles have 180 degrees.

In order that all sides be 12cm long, you need to draw a base line that goes on for more than 12 cm.

Mark off the (using a ruler) a line that is 12 cm from one of the line written about.

From that same endpoint, draw an angle that is 60o. Draw a line going 60 degrees from your first line.

=============

Just to finish the triangle, go to the other end of the 12 cm line. Draw another 60 degree angle. Make it so that it will intersect the second line you drew.\
