A.
Gonzalez; 57 mi/h

B.
Gonzales; 59 mi/h

C.
Wilson; 57 mi/h

D.
Wilson; 59 mi/h

WORTH 8 POINTS!

Answers

Answer 1

Answer:

The Gonzalez family drove 342 miles in 6 hours. 342 ÷ 6 = 57 mph

The Wilson family drove 472 miles in 8 hours. 472 ÷ 8 = 59 mph

So your answer is D. Wilson; 59 mi/h

Hope this helps. :)

Answer 2

Answer: 342 miles ÷ 6 hours = 57 mph (Gonzales Fam)
472 miles ÷ 8 hours = 59 mph (Wilson Fam)
Teh Wilson Fam drove faster than the Gonzales Fam, so the answer is D

COULD SOMEONE HELP EXPLAIN THIS TO ME? I'M REALLY CONFUSEDThe scatter plot below shows the number of pizzas sold during weeks when different numbers of coupons were issued. The equation represents the linear model for this data.

y = 3.4x + 43

According to the model, how many more pizzas are sold for each additional coupon issued?

1 pizzas

3.4 pizzas

4.3 pizzas

43 pizzas

46 pizza

Answers

Answer:

B. 3.4 pizzas.

Step-by-step explanation:

We have been given a scatter plot, which represents the number of pizzas (y) sold during weeks when different numbers of coupons (x) were issued. The equation represents the linear model for this data: $y=3.4x+43$

We can see that our given equation is in form of slope intercept form: $y=mx+b$ , where m= slope of line and b = y-intercept.

We can see from our given equation that y-intercept is 43, when no coupons were issued, there were 43 pizzas sold. 43 is constant and it will not change by any change in x.

The slope of our line is 3.4, which represents change in number of pizzas with respect to change in number of coupons issued. Therefore, 3.4 more pizzas are sold for additional coupon issued and option B is the correct choice.

Answer: B. 3.4

Step-by-step explanation:

We can see that our given equation is in form of slope intercept form: , where m= slope of line and b = y-intercept.

We can see from our given equation that y-intercept is 43, when no coupons were issued, there were 43 pizzas sold. 43 is constant and it will not change by any change in x.

The slope of our line is 3.4, which represents change in number of pizzas with respect to change in number of coupons issued. Therefore, 3.4 more pizzas are sold for additional coupon issued and option B is the correct choice.

A Ferris wheel can accommodate 55 people in 25 minutes. How many people could ride the Ferris wheel in 3 hours. What was the rate per hour

Answers

The best way to find out how many people can be accommodated in 3 hours, is to convert this to minutes, and then divide by 25 (as this will show how many times it can be ridden in the three hour period). 3 hours is equal to 180 minutes. Therefore, 180/25 is equal to 7 (with a remainder of 5 minutes). As there can be 7 slots of 55 people, you have to multiply these together, and this gives you 385 people. You still have 5 minutes remaining, and the best way to do this is to find the highest common multiple of 55 and 25, which is 5, and divide both of these by 5. Meaning that in 5 minutes, there are 11 people. You then have to add this to 385, giving you 396.
In order to find the hourly rate, just multiply the 11 riders in 5 minutes by 12 (as there are 12 lots of 5 in 60), and this will give you 132 people.

396 people are able to ride the Ferris Wheel in three hours.
The rate of people per hour is 132.
