Answer:
132 miles
Step-by-step explanation:
miles ran + miles to run = total miles
28 + miles to run = 160
Subtract 28 from each side
28-28 + miles to run = 160-28
miles to run = 132
He still need to run 132 miles
Answer:
132 mi
Step-by-step explanation:
since he ran 28 miles but he has to run 160 miles, he still has to run some miles. if we make the amount he still has to run x, we can do 28+x=160. now we can solve this by subtracting 28 on both sides to getx=132
28+x=160
-28 -28
-------------------------
x=132
A and B are independent events. P(A)=0.60 and P(B)=0.30
what is P(A and B)
Answer:
0.18
Step-by-step explanation:
This is a very simple problem that can be solved with a simple formula.
When there are two independent events A and B, the formula is:
P(A and B) = P(A) * P(B)
So we just need to multiply P(A) and P(B) to get P(A and B).
Thus,
P(A and B) = P(A) * P(B) = 0.60 * 0.30 = 0.18
Answer:
P (A and B) = 0.18
Step-by-step explanation:
We are given that A and B are independent events which means that occurrence of one event does not have any impact on the other event.
Given that P(A)=0.60 and P(B)=0.30, we are to find the probability P(A and B).
To find this, we just simply need to multiply the probabilities of the two events.
P (A and B) = 0.60 × 0.30 = 0.18

a car made a 60 mile trip at an average speed of 20 mph. On the return trip, the car's average speed was 30 mph. What was the average speed of the car car for the entire two-way trip?
Answer:
The average speed of the car is [tex]s = 24\ mph[/tex]
Step-by-step explanation:
The average speed is defined as
[tex]s = \frac{d_1}{t}[/tex]
Where
s is the speed
d is the displacement made
t is the time it took to perform the displacement d.
On the first trip the speed was 20 mph and the displacement was 60 miles. Then we find the time [tex]t_1[/tex]
[tex]s = \frac{d}{t}[/tex]
[tex]t_1 = \frac{d_1}{s}\\\\t_1 = \frac{60}{20}\\\\t_1 = 3\ h[/tex]
On the second trip the speed was 30 mph and the distance traveled was the same: 60mph
We calculate [tex]t_2[/tex].
[tex]t_2 = \frac{60}{30}\\\\t_2 = 2\ h[/tex].
Now we can calculate the average speed for the entire route
[tex]s = \frac{d_1 + d_2}{t_1 + t_2}\\\\s = 60 +\frac{60}{3} +2\\\\s = \frac{120}{4}\\\\s = 24\ mph[/tex]
Answer:
Speed = 24 mph
Step-by-step explanation:
Distance traveled in the two way trip
2*(60 miles) = 120 miles
Time it took to arrive to the destination (first travel, 60 miles, 20mph)
Speed = distance/ time
t = distance/ speed = (60 miles) / (20 mph) = 3 hours
Time it took to come back (return travel, 60 miles, 30 mph)
t = (60 miles) / (30 mph) = 2 hours
Total time = (3 +2) hours = 5 hours
So the average speed is
Speed = (120 miles) / (5 hours) = 24 mph

Step-by-step explanation:
Amy is putting a new floor in her bathroom. She created a scale drawing of her bathroom floor using a scale of 1/2 inch = 1 foot. In the drawing, the bathroom measures 3 inches by 3 1/2 inches. Amy is purchasing square tiles that measure
1/2 foot on each side. The cost of each tile is $3.00. How much will Amy pay for the tiles for her bathroom floor?
Answer:
$78.00
Step-by-step explanation:
First, you would have to figure out how many tiles she would need. 3 inches is equal to 6 feet according to the scale part, and then it would be 12 tiles because it is half a foot for the tiles. Then 3 1/2 would be 7 feet, and then 14 tiles. 12 plus 14 equals 26, and 26 times $3.00 is $78.00
Amy will pay $3.00 for the tiles for her bathroom floor.
What is Fraction?A fraction represents a part of a whole.
The scale is 1/2 inch = 1 foot.
Length of bathroom = 3 inches × (1 foot / 24 inches)
= 1/8 feet
Width of bathroom = [tex]3\frac{1}{2}[/tex] inches(1 foot / 24 inches)
= 7/24 feet
We need to calculate the total area of the bathroom floor in square feet:
Area of bathroom floor = (length) x (width)
= (1/8 feet) x (7/24 feet)
= 7/192 square feet
Since each tile measures 1/2 foot on each side, the area of each tile is:
Area of one tile = (1/2 feet) x (1/2 feet) = 1/4 square feet
Total area of tiles needed = (area of bathroom floor) / (area of one tile)
= (7/192 square feet) / (1/4 square feet)
= 7/48 tiles
Amy will need to purchase 1 tile at a cost of $3.00 per tile, so the total cost of the tiles for her bathroom floor will be:
Total cost = (number of tiles) x (cost per tile)
= 1 tile x $3.00/tile = $3.00
Hence, Amy will pay $3.00 for the tiles for her bathroom floor.

Answer:
Option B.
Step-by-step explanation:
Each summation symbol tells you to add terms. The terms are obtained by replacing n in the expression with the integers 1, 2, 3, 4, 5, and 6.
Let's look at option A:
The expression is 2(2)^n.
Replacing n with 1, 2, ..., 6 gives us these terms, which are added:
2(2)^1, 2(2)^2, 2(2)^3, 2(2)^4, 2(2)^5, 2(2)^6
The terms above simplify to:
4, 8, 16, 32, 64, 128
Clearly these are not the terms in the series you are given, so option A is not the answer.
Let's now look at option B:
Replacing n in 2n with 1, 2, 3, ..., 6 gives us:
2(1), 2(2), 2(3), 2(4), 2(5), 2(6) which simplifies to 2, 4, 6, 8, 10, 12.
Since it's a summation, you add the terms above to get
2 + 4 + 6 + 8 + 10 + 12
Option B is the answer.

Jaclyn gets a hit 40% of the time while playing softball. She is going to use colored tiles to simulate her chances of getting a hit. Green tiles will represent hits, while red tiles will represent times Jaclyn does not get a hit. She will place the tiles in a bag, and then draw the tiles from the bag one at a time. Jaclyn places 12 green tiles in a bag. How many red tiles should she place in the bag?
Answer:
18 red tiles
Step-by-step explanation:
One way to look at this problem would be to take the number of tiles that Jaclyn used to get a possibility of 40% hits.
Jaclyn put 12 green tiles, this represents the 40% of the hits that she could get.
Now we know that 12 = 40%
We need to find how many red tiles she should put to still keep the 12 green tiles as 40%. We can also assume that 12 red tiles would be another 40%.
So we have 12 red tiles currently.
Now we still have another 20% left.
Since 12 red tiles = 40%, we can assume that:
6 red tiles = 20% of the total.
So if we add both the 40% red tiles to the 20% red tiles we get:
12 + 6 = 18 red tiles.
So Jaclyn will have to put 18 red tiles and 12 green tiles to simulate her chances of getting a hit.

The length of a rectangle is shown below:
If the area of the rectangle to be drawn is 10 square units, where should points C and D be located, if they lie vertically below the line that connects B and A, to make this rectangle?
C(-1, 1), D(1,1)
C(-1, -2), D(1,-2)
C(-1, 5), D(1, 5)
C(-1, -7), D(1, -7)
Answer: Second option.
Step-by-step explanation:
As you can see in the graph attached, the lenght of the side AB is 2 units.
The formula for calculate the area of rectangle is:
[tex]A=l*w[/tex]
Where l is the length and w is the width.
Therefore, if the area of the rectangle to be drawn is 10 square units and you know AB=2 units and CD lies vertically below BA , then you can solve for the length:
[tex](10units^2)=(2units)l\\l=5units[/tex]
Therefore C and D are located at:
[tex]C=B(-1, 3-5)=> C(-1,-2)[/tex]
[tex]D=A(1, 3-5)=> D(1,-2)[/tex]
Answer:
The correct answer is,
Option 2). C(-1, -2), D(1,-2)
Step-by-step explanation:
It is given that,If the area of the rectangle to be drawn is 10 square units
To find the length of rectangle
From the figure we get length of AB = 2 units
Therefore Area = length * breadth = 10
Therefore length = 10/2 = 5 units
To find the points of C and D
we have B(-1, 3)
The point C is 5 units below the point B
Therefore C(-1, 3-5) = C(-1,-2)
we have A(1, 3)
The point D is 5 units below the point B
Therefore D(1, 3-5) = A(1,-2)
Therefore the correct answer is option 2
