Answer 1

Answer:

130 miles

Step-by-step explanation:

So, lets go over what we know:

She drove 40 miles per hour for 30 minutes.

Or:

She drove 40 miles per hour for 1/2 hours.

Or:

She drove 20 miles.(40*1/2=20)

We also know:

She drove 55 miles per hour for 2 hours.

Or:

She drove 110 miles(55*2=110)

To find the total miles, we must add the 20 and 110:

110+20

130

So she drove a total of 130 miles!

Hope this helps! :D

Advanced question. Who can figure out how you can take an exchange rate which pegs $1.00 US to $1.21 CAD to see how much you would get in $US for $1.00 Cdn? It will be less than $1.00.

Answers

Answer:

$0.83 when solved for (when the actual conversion is done it comes out to be $0.82)

Step-by-step explanation:

We are stating that 1 US = 1.21 CAD

Since they are equal we can assume: [tex]\frac{1 US}{1.21 CAD} =1[/tex]

Assume the number we are looking for is x. x US = 1 CAD.

Since they are equal we can assume: [tex]\frac{x US}{1 CAD} =1[/tex]

Both equations are equal to 1, meaning the equations are equal to each other. So, [tex]\frac{1US}{1.21CAD}=1= \frac{xUS}{1 CAD}[/tex] ⇒⇒⇒⇒ [tex]\frac{1US}{1.21CAD}= \frac{xUS}{1 CAD}[/tex]

Using cross multiplication we get [tex]1US*1CAD=1.21CAD*xUS[/tex]

We can discard the units (we only needed them to differentiate which currency we were talking about) to get 1 = 1.21x

Solving for x we get x = 1/1.21 = 0.82645

If you wish to round this you would get around 0.83, which is remarkably close to the actual price of 0.82. The reason for difference is in the numbers we use. When we divide 1/1.12131, we get 0.82433, which would round to be 0.82.

Hope this is correct and helps!

the answer is 0.83. explication

A zoo measured the wingspan, in millimeters, of 9 butterflies.
55 50 54 57 50 55 53 52 55
What is the median length of the wingspans?

50 millimeters

54 millimeters

55 millimeters

57 millimeters

Answers

Answer:

The median is the middle of your data when it is arranged in order.

Since you have 9 data points, the median will be the 5th value.

Your data in numerical order would be:

50 50 52 53 54 55 55 55 57

Therefore, the median is 54mm

Step-by-step explanation:

Answer:

B. 54

Step-by-step explanation:

Put all numbers from least to greatest in order and cross one out on each side until you reach the final number in the middle with even crosses on each side.

50, 50, 52, 53, 54, 55, 55, 55, 57

50- crossed

57- crossed

50- crossed

55- crossed

52- crossed

55- crossed

53- crossed

55- crossed

Which leaves 54! Hope this helps, good luck! :)

hayley wants to attend bellhaven collage after high school. she knows that the yearly cost is around $17000 per year. her parents started a college account for her when she was born with an inital amount 2000 and a 6% simple interest rate. it has been open for 18 years. hayley will also be given an academic achievement scholarship for $1000 for her first year of college. how much more will hayley need in order to pay for her first year of college if she uses all of the money she has available? Please show work too. You get 13 points if you answer and show your work.

Answers

i think the answer is 13,840

to start off use the formula IPRT which stands for interest, principal, rate, and time. so then you do 2,000 times 6% (or 0.06) then times that by 18 which is 2,160 so she earned 2,160 in her college account, next you add the 1,000 and that would make it 3,160. next you subtract 3,160 from 17000 to see how much she still has to pay which i think is 13,840

Geneva has a spinner with eight equal parts numbered one thru eight. If Geneva spins the spinner one time, what is the probability that the spinner will land on the number two?

A. 1/8
B. 2/8
C. 8/2
D. 8/1

Answers

Answer: I would go with A. 1/8

Step-by-step explanation: if she is only spinning it one time, and she is hoping to get 1 specific answer and there are 8 options, then 1/8 is the only one that makes sense. That’s a 12.8% chance of landing on two. I apologize if I’m incorrect.

Answer: A

Explanation: A would be the right answer because it says equal parts. If it weren’t equal then the probability would be all messed up.

Answer:

The function in the table has a greater y-intercept than the graph does.

Step-by-step explanation:

y-intercept = a point in the function where x=0,

=> In the graph y-intercept is at the coordinate (0,-2) so the y-intercept is -2.

=> In the table y-intercept is at the coordinate (0,5) so the y-intercept is 5

Hope this helps!

The table has a higher y-intercept.
The graph shows a y-intercept of -2, because the line is crossing over that point on the y-axis.
The table shows that when x is 0, the y intercept is 5.
Meaning the tables y-intercept is higher.

Volume of 1 is 9^2 units. Volume of 2 is 8^2units.

Step-by-step explanation:

Due to not having a unit amount we have to assume each square equals 1 unit. From that we also have to assume the squares we can not see are also there.

How I got the answer is I simply counted the boxes due to them only be 1 unit^2 in volume they always will be 1 so you can just count.

First one would be 9 cubed units and the second one would be 8 cubed units
