Answer:
6 and 2/3
Step-by-step explanation:
56 and 2/3 divided by 8 1/2
Rewrite the mixed numbers as a fractions greater than 1.
56 and 2/3 divided by 8 and 1/2 = 170/3 divided by 17/2.
Rewrite the problem as a multiplication using the reciprocal of the divisor.
170/3 divided by 17/2 = 170/3 x 2/17
= 170 x 2
3x17
cross out 170 to 10. Then cross out 17 to 1.
= 20/3, or 6 an 2/3
If we have the expression 2b = -3, then the value of the expression 1 - 4b is 4.
Step 1: Solving for 'b'
We are given the equation 2b = -3. To isolate 'b,' we need to get rid of the coefficient 2 attached to 'b'. To do that, we'll divide both sides of the equation by 2:
2b / 2 = -3 / 2
b = -3/2
Step 2: Substitute 'b' in the expression 1 - 4b
Now that we have the value of 'b' as -3/2, we can substitute it into the expression 1 - 4b:
1 - 4(-3/2)
Step 3: Simplify the expression
To simplify the expression, we'll perform the multiplication first:
1 + 6/2
Next, we add 1 and 6/2:
1 + 3 = 4

Answer:
Step-by-step explanation:
2b= -3, what is the value of 1 – 4b?
2b= -3
b = -3/2
Then 1 - 4b
= 1- 4(-3/2)
= 1+12/2
= 1+ 6
= 7
Answer:
57
Step-by-step explanation:
Because side BD is similar to side BA
triangle BCD seems to be double the size of triangle BAD
By finding the side lengths of the missing sides BC and CD you can get the perimeter.
Because we know the triangle is double the size you can double the lengths of AD and BD to get 24 and 18, if you add 6,9,24, and 18. You will get 57.
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?
have you finished this yet? im doing it rn and i need help on some of them. if you havent i can help you with a couple answers
Answer:
If you divide first (2 ÷ 3/4) just multiplu when you check your math.
