The scale from a map to the actual distance is 2.5 cm to 620 mi. The distance on the map between Chicago and Boston is about 3.5 cm. What is the approximate distance, in miles, between Chicago and Boston? Show your work.
Answer 868 miles
Step by step
Given: The scale from a map to actual distance is 2.5 cm to 620 miles. If the distance on the map between Chicago and Boston is about 3.5 cm. Hence, the approximate distance between Chicago and Boston = 868 miles.
If the distance on the map between Chicago and Boston is about 3.5 cm.
Then, the actual distance between them = 3.5\times 248 \text{ miles}=868 \text{ miles}
Hence, the approximate distance between Chicago and Boston = 868 miles.
i.e. 1 cm on map = 620/2.5 miles = 248 miles
Answer:868 miles
Step-by-step explanation: 1cm=620/2.5 = 248
distance is about 3.5
3.5x 248=868

slope intercept form parallel to y = -x + 3 and through (0,6)
Answer:
Step-by-step explanation:
parallel means the slope is the same
y = -x + b
since it has to pass thru (0,6) we’ll plug those in to the equation to find b
6 = -(0) + b
6 = b
the final equations is y = -x + 6

Danielle created a painting using only similar hexagons.
Which statement about the hexagons must be true?
The hexagons are all the same size and shape.
The hexagons have corresponding sides that are proportional.
The hexagons have corresponding angles that are not congruent.
The hexagons are different shapes but the same size.
Answer: B- The hexagons have corresponding sides that are proportional.
The statement is true about hexagons, if Danielle created a painting using only similar hexagons, The hexagons have corresponding sides that are proportional, so option B is correct.
What is a hexagon?A hexagon is a two-dimensional geometric shape with six sides that may or may not have the same length. The hexagon shape can be seen in everyday objects like floor tiles, pencil cross-sections, clocks, honeycombs, etc.
Given:
Danielle created a painting using only similar hexagons,
A closed, two-dimensional shape with six equal sides and six equal angles is referred to as a regular hexagon. The regular hexagon has 120-degree angles on each side. And 120 x 6 = 720 degrees is the total of all inner angles.
Both have 6 vertices, 6 internal angles, and 6 sides, All six inner angles add up to 720 degrees, All six outer angles added together result in 360 degrees. These two hexagons are comparable because they have matching sides in the same ratio and matching angles that are both equal.
Thus, hexagon hexagons have corresponding sides that are proportional.

5. 24 points scored in 4 games; a points scored in 10 games
Complete Question:
24 points scored in 4 games; a points scored in 10 games. Are they equivalent?
Answer:
Both games are not equivalent
Step-by-step explanation:
Given
[tex]24\ points = 4\ games[/tex]
[tex]1\ point = 10\ games[/tex]
Required
Determine if they are equivalent
We have that:
[tex]24\ points = 4\ games[/tex] ----- (1)
[tex]1\ point = 10\ games[/tex] ----- (2)
To solve this, we simply make the number of games equal.
Multiply (1) by 2.5
[tex]2.5 * 24\ points = 4\ games * 2.5[/tex]
[tex]60\ points = 10\ games[/tex]
This implies that there are 60 points in 10 games
While for (2):
[tex]1\ point = 10\ games[/tex] means that
There are 1 point in 10 games
Hence, both games are not equivalent
Because, the number of points differ in the same number of games

Answer:
42 tickets
Step-by-step explanation:
If you divide all the choices by 8 they all equal an even number except 42
it is not possible for them to use forty-two tickets because forty-two is not a multiple of eight. since there are eight people, and each ride cost one ticket per person, they should use eight tickets for each ride. forty, twenty-four, and sixteen are all multiples of eight, and are therefore possible answers.
What is the decimal equivalent of 9 1/2%
The decimal equivalent of 9 1/2% is 0.095.
We have,
To explain the process of finding the decimal equivalent of 9 1/2%, we need to understand what a percentage represents and how to convert it to a decimal.
A percentage is a way of expressing a part of a whole in terms of hundredths. In this case, 9 1/2% represents 9.5 parts out of 100.
To convert a percentage to a decimal, we divide the percentage value by 100. This is because a percentage is essentially a fraction with a denominator of 100.
Now,
To find the decimal equivalent of 9 1/2%, we divide the percentage value by 100.
9 1/2% can be expressed as a fraction: 9 1/2% = 9.5/100.
Dividing 9.5 by 100 gives us the decimal equivalent:
= 9.5 ÷ 100
= 0.095
Therefore,
The decimal equivalent of 9 1/2% is 0.095.

Noel works as a driver for a transportation company. On average, he drives 152 hours to make 19 successful deliveries. Assume this rate is his
constant rate for delivering goods. If you graph this relationship with time along the x-axis and number of deliveries along the y-axis, the slope of
the line you get gives Noel's unit rate for a successful delivery. Which unit rate can be interpreted as the slope?
So I have this test too and I'm pretty sure it's 8. I will check back when I know for sure and have my answer submitted.
Edit:
Yes the answer I originally gave is correct.
Noel's unit rate for successful delivery is 1/8 of a delivery per hour option (D) is correct.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
The missing options are:
A. 8 deliveries per hour
B. 2/17 of an hour per delivery
C. 1/8 of a delivery per hour
D. 1/8 of an hour per delivery
We have:
On average, he drives 152 hours to make 19 successful deliveries.
The rate is constant.
The total time for which Noel drives = 152 hours
The total number of successful deliveries = 19
Noel's unit rate for a successful delivery
= total successful deliveries/total hours
= 19/152
Divide by 8 on the numerator and denominator:
= 1/8
y = (1/8)x
Here x represents time
y represents the number of deliveries
Thus, Noel's unit rate for a successful delivery is 1/8 of a delivery per hour option (D) is correct.

An experiment consists of dealing 6 cards from a standard 52-card deck. What is the probability of being dealt 6 hearts?
Answer: 0.0000842890
Step-by-step explanation:
Given that :
Number of cards in a deck = 52
Number of hearts in a deck = 13
Probability of being dealt 6 hearts :
Probability = (required outcome / Total possible outcomes)
Required outcome = choosing 6 hearts from a possible 13
13C6:
Recall : nCr = (n! / (n-r)!r!)
13C6 = 13! / (13-6)!6!
13C6 = 13! / 7!6!
13C6 = (13*12*11*10*9*8)/(6*5*4*3*2*1)
13C6 = 1235520 / 730
13C6 = 1716
Total possible outcomes :
52C6 = 52! / (52-6)!6!
52C6 = 52! / 46!6!
52C6 = (52*51*50*49*48*47)/(6*5*4*3*2*1)
52C6 = 14658134400 / 720
52C6 = 20358520
Hence,
P(6 hearts) = 1716 / 20358520
P(6 hearts) = 0.0000842890
College roommates John and David were driving home to the same town for the holidays. John drove 55mph, and David, who left an hour later, drove 60mph. How long will it take for David to catch up to John?
Answer:
sorry
Step-by-step explanation:
It will take for David 11 hours to catch up with John
Speed is the ratio of distance traveled to the total time taken. Speed is given by:
Speed = distance / time
Let d represent the distance at which both John and David meet up at time t hour.
Since drove at 55 mph and is an hour faster, hence:
55 = d / (t + 1)
d = 55t + 55 (1)
John is driving at 60 mph, hence:
60 = d / t
d = 60t (2)
equating equation 1 and 2:
55t + 55 = 60t
5t = 55
t = 11 hours
Hence, it will take for David 11 hours to catch up with John
