Write a real world problem that correspond to the equation 10x + 30 =100?

Answers

Answer 1

Answer: 10x + 30 = 100

Here is a real world problem to demonstrate this.

Mack decides to burn some calories, so he attends a gym. A cost of a gym costs 10 dollars per month, with an addition registration fee of 30 dollars. Mack has spent 100 dollars on the gym so far. How many months has he been participating at the gym?

Let 'x' represent the amount of months spent.

Answer 2

Answer:
Saturday night after the marshmallows ran out, the counselor
threw 30 cold stones on the campfire, and sent the campers
to bed in their tents.

But several campers noticed that there were still live coals in
the fire. This was a tent situation, and they knew that they
should not leave until it's completely out. So they each
picked up 10 cold stones and they all threw those on the fire
too. Then the fire was really out, so they all went to their tents.

In the morning the same campers who threw 10 stones apiece
onto the fire all got together and went to look at it. It was definitely
stone cold, so they spread it out and counted all the stones in it.
They found that there were exactly 100 stones. How many
campers threw stones on the fire after the counselor left ?

HHHEEELLLPPP!!!! MY ENTIRE SUMMER DEPENDS ON THIS!!IF YOU CAN’T LEGITIMATELY ANSWER, DON’T BOTHER EVEN TRYING.Test to see how many boxes of Lucky Chocolate Oat Crunch need to be purchased to collect all eight dinosaurs. Use the spinner provided to simulate the purchase of the cereal boxes. Each time the spinner is spun, it represents the purchase of one cereal box. As you spin, you will need to keep track of your results. You will use the results to compute the experimental probability, which you will compare with the theoretical probability. Use the spinner below to determine how many boxes of cereal you might need to purchase to collect all eight dinosaurs. Continue until the spinner has landed on each dinosaur once. Be sure to stop spinning once the spinner has landed on each dinosaur one time. Each number on this spinner represents a different dinosaur. You need to complete the simulation three times. That is, after each dinosaur has been spun one time, record your results. Then, create a new chart for the next set of results. When you are finished, you will have three sets of data that will most likely not match. (ALREADY COMPLETED THIS PART, THE CHARTS ARE BELOW)Use all three sets of data to answer the following questions in complete sentences. For this exercise, the probabilities refer to the probability of getting any one dinosaur when making any one purchase. You do not need to determine the probability of the compound event of getting all eight of the dinosaurs. Make sure to have all three simulations done to help you answer these questions in the writer's box:(NEED HELP WITH THIS. ANSWERED A FEW ALREADY, NEED HELP WITH THE ONES SHOWN)1. How does the number of spins correlate to the number of boxes of cereal that you would need to purchase?2. What was the experimental probability for EACH dinosaur from Trial 1? Trial 2? Trial 3?3. How does the experimental probability of getting each dinosaur differ from the theoretical probability? Here, you are comparing the experimental vs. theoretical probability of getting each type of dinosaur in a single purchase. In other words, you are determining the probability for a single event, not a compound event.4. If someone bought eight boxes of cereal and got all eight dinosaurs, would you be surprised? Why or why not?5. How did the experimental probabilities change between the trials?6. What are the advantages of using a simulation versus actually buying boxes of cereal?

Round to nearest 10,000 to 591,563

Answers

590000
The 1000 place is 1 which is less than 5 so it gets rounded down

That would be 59,000 because the 9 is in the ten thousandths place and you have to look to the number at the right to see if you should keep the number the same or go up one. In this case, it would stay the same

Plot the zeros of the polynomial y = x4 + 3x3 − 27x2 + 13x + 42

Answers

Answer:

See explanation

Step-by-step explanation:

Consider the polynomial $y=x^4+3x^3-27x^2+13x+42$ 4th power polynomial function has at most 4 zeros.

Integer zeros can be only among the divisors of 42:

$\pm1, \ \pm 2,\ \pm 3,\ \pm 6,\ \pm 7,\ \pm 14,\ \pm 21,\ \pm 42$

Check them:

$y(1)=1^4+3\cdot 1^3-27\cdot 1^2+13\cdot 1+42=1+3-27+13+42=32\neq 0\n \ny(-1)=(-1)^4+3\cdot (-1)^3-27\cdot (-1)^2+13\cdot (-1)+42=1-3-27-13+42=0\n \ny(2)=2^4+3\cdot 2^3-27\cdot 2^2+13\cdot 2+42=16+24-108+26+42=0\n \ny(3)=3^4+3\cdot 3^3-27\cdot 3^2+13\cdot 3+42=81+81-243+39+42= 0\n \ny(-7)=(-7)^4+3\cdot (-7)^3-27\cdot (-7)^2+13\cdot (-7)+42=2,401-1,029-1,323-91+42= 0$

Thus,

$y=(x+7)(x+1)(x-2)(x-3)$

Zeros are plotted in attached diagram.

Answer:

The remainder is 0, so -1 is a zero of the polynomial and x + 1 is another factor: (x − 2)(x + 1)(x2 + 4x − 21). Now factor the remaining polynomial using normal means. The fully factored form is (x − 2)(x + 1)(x + 7)(x − 3), so the zeros of the polynomial are x = 2, -1, -7 and 3.

Plis help me!!

Answers

Answer:

x = 4

Step-by-step explanation:

Given

- 8 - x = x - 4x, that is

- 8 - x = - 3x ( add 3x to both sides )

- 8 + 2x = 0 ( add 8 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Answer:x=4

Step-by-step explanation:

-8-x=x-4x

-8=-4x+x+x

-8=-2x

divide both sides by -2

x=4
