Jeremy has saved $440 from his summer job. He plans to set aside $55 each week for his expenses. Several weeks later he has $110 left.How many weeks have passed?

Answers

Final answer:

To find out how many weeks have passed, we subtract the remaining amount from the initial amount, and then divide by the amount saved each week. In this case, 6 weeks have passed.

Explanation:

To find out how many weeks have passed, we need to subtract the remaining amount from the initial amount, and then divide by the amount saved each week.

Initial amount saved = $440

Amount saved each week = $55

Remaining amount = $110

Weeks passed = (Initial amount saved - Remaining amount) / Amount saved each week

= ($440 - $110) / $55

= $330 / $55

= 6 weeks

Therefore, 6 weeks have passed.

C.Kasimir should have divided by 100,000.
D.Kasimir should have multiplied by 0.001.

Answers

C:Kasimir should have divided by 100000 is the answer

Answer:

c) Kasimir should have divided by 100,000.

Step-by-step explanation:

Given that Kasimir rode his bike 34,478 centimeters.

We have the table

10 mm=1 cm

10 cm =1dm

10dm = 1 m

...

Hence we have 100 cm = 1 m

100x1000 cm = 1 km

1 km = 34478/100000 = 0.34478

Hence C) is right

Kasimir should have divided by 100,000.

Ellen is drawing two polygons one of the polygons has 3 more angles than the other what shape could she be drawing

Answers

Answer:

Step-by-step explanation:

The attachment shows different types of polygons.

Now depending on these we have following five possibilities:

Case 1: Triangle and hexagon

If first polygon is triangle with three angles, the second will have 6 angles and the second polygon will be hexagon.

Case 2: Quadrilateral and heptagon

If first polygon is quadrilateral with 4 angles, the second will have 4+3 =7 angles and the second polygon will be heptagon.

Case 3: Pentagon and Octagon

If first polygon is pentagon with 5 angles, the second will have 5+3=8 angles and the second polygon will be octagon.

Case 4: Hexagon and Nonagon

If first polygon is hexagon with 6 angles, the second will have 6+3=9 angles and the second polygon will be nonagon.

Case 5: Heptagon and Decagon

If first polygon is Heptagon with 7 angles, the second will have 7+3=10 angles and the second polygon will be decagon.

Depend on the possibilities, which figure Ellen is drawing.

What is polygon?

A closed, two-dimensional form with straight line segments is called a polygon. It does not have three dimensions. A polygon has flat surfaces throughout. A polygon must have three sides at a minimum. Only at its terminal must each side of a line segment cross another line segment. Depending on a polygon's number of sides.

Given Ellen is drawing two polygons one of the polygons has 3 more angles than the other,

Now, based on these, there are the five options listed below:

Case 1: Hexagon and triangle

If the first polygon is a triangle with three angles, the second polygon will be a hexagon with six angles.

Case 2: Heptagon and quadrilateral

If the first polygon has a quadrilateral shape and four angles, the second polygon will have four plus three more angles, making it a heptagon.

Pentagon and Octagon in Case 3

If the first polygon has a pentagon shape with five angles, the second will have an octagon shape with five plus three equals eight angles.

Hexagon and Nonagon in Case 4

If the first polygon has a hexagon shape and 6 angles, the second will have 6 + 3 = 9 angles and be a nonagon.

Heptagon and Decagon in Case 5

if the initial polygon is a hexagon, then The first polygon has 7 angles, the second has 7+3=10 angles, and the third is a decagon.

Hence the shape of polygon depend on these possibilities.

The average rate of change from x = 0 to x = 15 is about −4.667. How does the average rate of change from x = 0 to x = 20 compare to this number?

Suppose that the height of the slide is 2 feet, when x = 20. What is the average rate of change over the entire slide?

Answers

First we calculate the ambio rate from x = 0 to x = 15:
 We have:
 R = ((80-10) / (0-15))
 R = -4.666666667
 We now calculate for the entire interval:
 from x = 0 to x = 20:
 R = ((80-2) / (0-20))
 R = -3.9
 Answer:
 What is the average rate of change over the entire slide?
 R = -3.9
 The average rate of change from x = 0 to x = 15 is about -4.667. How does the average rate change from x = 0 to x = 20 compare to this number?
 The percentage difference is:
 (-3.9 / -4.666666667) * (100) = 83.57142857%
 100-83.57142857 = 16.42857143%

The average rate of change over the entire slide is -0.05.

The average rate of change from x = 0 to x = 15 is calculated by finding the slope of the secant line that intersects the graph of the function at x = 0 and x = 15.

The slope of the secant line is:

m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])

= (-2 - 15)/(15 - 0)

= -17/15

= -1.133

The average rate of change from x = 0 to x = 20 is calculated by finding the slope of the secant line that intersects the graph of the function at x = 0 and x = 20.

The slope of the secant line is:

m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])

= (2 - 15)/(20 - 0)

= -13/20

= -0.65

The average rate of change from x = 0 to x = 20 is smaller than the average rate of change from x = 0 to x = 15.

This is because the slope of the secant line is getting closer to 0 as the interval gets larger.

If the height of the slide is 2 feet when x = 20, then the average rate of change over the entire slide is:

m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])

= (2 - 1)/(20 - 0)

= -1/20

= -0.05

The average rate of change over the entire slide is also negative, but it is much smaller than the average rate of change from x = 0 to x = 15.

This is because the slope of the secant line is getting closer to 0 as the interval gets larger.

in the right triangle what is the value of pq

Answers

In this Pythagorean theorem question, The value of pq in the right triangle is 8 cm. Therefore, the correct answer is option C.

The given triangle is a right triangle, with two sides measuring 17 cm and 15 cm. The side opposite the right angle (perpendicular) is represented by the variable pq.

To find the value of pq, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. So, applying the Pythagorean theorem:

a2 + b2 = c2

(15 cm)2 + pq2 = (17 cm)2

225 cm2 + pq2 = 289 cm2

pq2 = 289 cm2 - 225 cm2

D.She must buy 20 or more bags.

Answers

Ling can buy 12 bags of balloons, but no more.

A

Answer:

Option A is the correct choice.

Step-by-step explanation:

We have been given that Ling must spend no more than $40.00 on decorations for a party. She has spent $10.00 on streamers and wants to buy bags of balloons as well. Each bag of balloons costs $2.50.

The inequality [tex]10+2.5x\leq 40[/tex] represents x, the number of bags she can buy given the spending limit and how much she has already spent on streamers.

Let us solve for x by subtracting 10 from both sides of our inequality.

[tex]10-10+2.5x\leq 40-10[/tex]

[tex]2.5x\leq 30[/tex]  

Now we will divide both sides of our inequality by 2.5.

[tex]\frac{2.5x}{2.5}\leq \frac{30}{2.5}[/tex]

[tex]x\leq 12[/tex]

Therefore, Ling can buy from 0 to 12 bags, but no more and option A is the correct choice.

David and Ryan go to the movie theater and purchase refreshments for their friends. David spends a total of $24.75 on 3 bags of popcorn and 5 drinks. Ryan spends a total of $33.00 on 9 bags of popcorn and 4 drinks. Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.

Answers

Final answer:

To find the price of one drink, we create a system of equations based on the purchases at the movie theater and solve it using the elimination method. The calculated price of one drink is $3.75, to the nearest cent.

Explanation:

David and Ryan's purchases at the movie theater can be represented by the following system of equations to find the price of one bag of popcorn (p) and one drink (d):

3p + 5d = 24.75

9p + 4d = 33.00

We'll solve this system using the substitution or elimination method. For this example, we will use the elimination method.

Multiply the first equation by 9 and the second by 3 to equalize the coefficients for p:

(3p + 5d) × 9 → 27p + 45d = 222.75

(9p + 4d) × 3 → 27p + 12d = 99.00

Subtract the second equation from the first:

27p + 45d - (27p + 12d) = 222.75 - 99.00

33d = 123.75

Divide by 33 to find the price of one drink:

d = 123.75 / 33

d = 3.75

So, the price of one drink is $3.75, to the nearest cent.

Jim has a quarter and Jane has a number cube. In two or more complete sentences, explain why Jim is just as likely to get a head as Jane is to get an even number.

Answers

Jim only has two outcomes with the coin flip so the probability of getting heads is 1/2 where as with a dice, Jane has 6 possible outcomes and the probability of getting an even number is 3/6. Hope this helps! :)
Answer:

Jim is just as likely to get a head as Jane is to get an even number since the chance or probability of getting a head for Jim and getting a even number for Jane are equal i.e. 1/2=0.5

Step-by-step explanation:

In a quarter there are just two outcomes-- Head and Tail

The probability of getting a head is: 1/2

Similarly in a number cube that has six possible outcomes i.e. {1,2,3,4,5,6}

The number of outcomes that represents a even number are: 3  

(Since outcomes are: 2,4 and 6)

Hence, the probability of getting a even number is: 3/6=1/2

Hence, we see that the probability of getting a head and a even number is same.

Solution:

The graph is Time versus Speed.

In figure (a), the graph has a speed or y-axis=23mi/h for time or x-axis=5seconds.

The car maintains a speed of 23mi/h for 5 seconds.

For next 5 seconds, in figure a the graph increases linearly or we have a acceleration and reaches to 46mi/h.

It accelerates to a speed of 46 mi/h in 5 seconds.

It maintains that speed for the next 5 seconds. In figure (a), after we reach speed=46mi/h, there is a straight line for 5 seconds at speed=46mi/h.

It took Jen, who biked at a speed of 12 mph, 20 minutes to get home. What is Jim’s speed, if it took him only 15 minutes to bike that distance?

Answers

You could find the distance first
v = 12 mph
t = 20 minutes = 20/60 = 1/3 of an hour
d = r * t
d = 12 * 1/3 = 4 miles.

And put that distance into Jim's time
d = 4 miles
r = ???
t = 15 minutes = 15/60 = 1/4 hour
r = d/t
r = 4/0.25 = 16 mph. I wish I could bike that quickly. 

There is another way to do it more directly. The distance is the same for both of them.
r*t = R*T
R Jim's speed and r is jen's speed.
12 * 1/3 = R * 1/4  Multiply both sides by 4
12 * 1/3 * 4 = R Cancel 12 and 1/3
R = 16.

Gabriel wants to solve the equation 5/8 m=25. What step should he do to get m by itself on one side of the equation?

Answers

He should first multiply both sides by 8, to get rid of the denominator.

5/8 m = 25
8(5/8 m) = 8(25)
5m = 200

He should then divide both sides by 5, to get rid of the coefficient

5m/5 = 200/5
m = 40

So m = 40 by these steps

Final answer:

To solve the equation 5/8 m = 25, Gabriel needs to multiply both sides of the equation by the reciprocal of 5/8, which is 8/5, to isolate m on one side. The result after simplification is m = 40.

Explanation:

To solve the equation 5/8 m = 25, Gabriel needs to isolate the variable m on one side of the equation. He should start by multiplying both sides of the equation by the reciprocal of the fraction that is multiplied by m, which is 8/5. Here's the step-by-step process:

Multiply both sides of the equation by 8/5 to cancel out the 5/8 on the left side:

(8/5) × (5/8) m = (8/5) × 25

Simplify the left side by canceling out the common factors in the fraction:

1 m = (8/5) × 25

Next, multiply the number 25 by 8/5 to find the value of m:

m = 25 × (8/5) = 40

Thus, the solution to the equation is m = 40.

As many landfills run out of space, some communities are making plans and tackling their heaping piles of garbage with innovative solutions. Of the garbage Americans produce every day, only about thirty percent reaches a recycling center. Education about how and what to recycle is costly but essential. Much of the junk we consume and throw out is not designed with recycling in mind. This solid waste creates one of the biggest problems: recyclable material is clogging landfills. In order to extend the lifespan of their landfills, some communities are expanding recycling programs and trying new technologies to turn trash into energy. A few cities are planning new energy plants that burn garbage to produce energy while still producing less pollution than landfills. Several other cities have facilities that use bioreactor landfills to speed up the decomposition process for trash from 100 years to 5-10 years. The costs and pollution generated by landfills force communities to think creatively about what to do with everything we throw out.Which of the following sentences from the paragraph is the topic sentence?1.
