Answer:
Mr. Johnson completed his travel in 15 minutes. But Mrs. Johnson leaves 10 minutes after he does. And to add her 12 minutes travel time, that means Mrs. Johnson will arrive in 22minutes.
Step-by-step explanation:
First, we need to find the distance (d) that Mr. Johnson traveled to be able to compute Mrs. Johnson's travel time.
To be able to do that, use the formula d = (s)(t).
d = (80miles/hr)(15mins)
d = (80miles/hr)(0.25hr)
d = 20 miles
Now that we know the distance from Cambridge to Newton, we can use this value to calculate the time Mrs. Johnson needs to complete her travel.
Using the formula t = (d)/(s);
t = (20miles)/(100miles/hr); we get:
t = 0.2hr or 12minutes
Carly placed 50 marbles in a bag. Fifteen of the marbles are pink, 8 marbles are black,
2 marbles are green, 18 marbles are clear, and 7 marbles are striped. Click and drag
the letters onto the probability scale to order the likelihood that the event will happen.
When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.
We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped
15P/50
8B/50
2G/50
18C/50
7S/50 for a total of 50 marbles
Now we use the chart to decide our awnsers
A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.
B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely
C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these
D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of these and gives us an even to likely chance of getting one of these.
E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.

What is the height of the square pyramid? Show work for full credit
A) 4
B) 8
C) 12
D) 16
Answer:
B
Step-by-step explanation:
Because the pythagorean theorem we know that s2 = r2 + h2, since r = a/2s2 = (1/4)a2 + h2, and s = √(h2 + (1/4)a2)
This is also the height of a triangle side

Answer:
A triangle is 180 degrees and you have a 30 and 50 angle so the third angle should equal 100. so the answer should be 45 and here's why
Step-by-step explanation:
Subtract 10 from both sides
2x+10=100
2x+10-10=100-10
Simplify
Subtract the numbers
2x=90
Divide both sides by the same factor
2x=90
2x/2 = 90/2
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
x=45
Solution
45

How many yards and feet are equivalent to 10,000 feet? (1 yard = 3 feet)
what are three ratios that are equivalent to 4:3.
Answer:
8:6 , 12:9 , 16:12
Step-by-step explanation:
To find equivalent ratios is like finding equivalent fractions :
We simply multiply both numbers of the ratio by the same number.
You can also do the reverse to simplify a ratio.
4:3 × 2 = (4×2):(3×2) = 8:6
4:3 × 3 = (4×3):(3×3) = 12:9
4:3 × 4 = (4×4):(3×4) = 16:12
Therefore 3 ratios that are equivalent to 4:3 are :
8:6 , 12:9 , 16:12

Miguel draws a square on a coordinate plane. One vertex is located at (5,4). The length of each side is 3 units. Circle the letter by all the ordered pairs that could be another vertex.
A. (5,1)
B. (5,7)
C. (7,8)
D. (2,6)
E. (2,1)
Answer:
A, B, and E.
Step-by-step explanation:
We know that one vertex is at (5, 4), and each side of our square is 3 units long.
Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3 units (if those vertexes are connected by the diagonal of the square).
Also remember that the distance between two points (a, b) and (b, c) is:
distance = √( (a - c)^2 + (b - d)^2)
So we need to find the distance between our point and all the ones given in the options:
A) the distance between (5, 4) and (5, 1) is:
distance = √( (5 - 5)^2 + (4 - 1)^2) = 3
Then point (5, 1) can be a vertex.
B) The distance between (5, 4) and (5, 7) is:
distance = √( (5 - 5)^2 + (4 - 7)^2) = 3
Then (5, 7) can be a vertex.
C) The distance between (5, 4) and (7, 8) is:
distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20
Point (7, 8) can not be a vertex.
D) The distance between (5, 4) and (2, 6) is:
distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13
Point (2, 6) can not be a vertex.
E) The distance between (5, 4) and (2, 1) is:
distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3
Then point (2, 1) can be a vertex.

Answer:

Step-by-step explanation:
Angle AFC is supplementary to angle CFE. Supplementary angles always equal 180 degrees. (180-120=60)
Answer:
1. 60
2. 120
3.30
Step-by-step explanation:
(Yes I know they aren't labeled one and two but I'll go in order from the questions)
1. It is 60, because it is an equilateral triangle so all angles are equal. 180/3=60.
2. There are two ways you can solve this problem. The first is using the vertical angle theorem. That makes it 120. Or, you can add all the angles you have already and remove it from 360.
360-120-60-60=120.
(you can tell it is not 60 because it is larger than a right angle in the picture)
3.x=30.The right angle is 90, and there is a 60 degree angle, so 90-60=30

In a bag, there are 100 same-sized chips labeled 1 through 100. If one chip is selected without looking, order the probabilities of the events below by placing the event with the greatest probability on top.
Answer:
a: 89/100
b: 19/100
c: 28/100
Step-by-step explanation:
for a, take every number greater than 10. there are 100 chips, so 89/100 chips are greater than 10. do this for each of the other questions.
The order for the probabilities of the events by placing the event with the greatest probability on top is
1. The label is a number between 30 and 60
2. The label is a number less than 20
3. The label is a number greater than 10
How did we arrive at this order?Below are the correct order of the probabilities from greatest to least:
1. The label is a number between 30 and 60
2. The label is a number less than 20
3. The label is a number greater than 10
The reason for this order is that there are 31 chips with labels between 30 and 60, 19 chips with labels less than 20, and 90 chips with labels greater than 10.
Therefore, the correct answer is as given above.
