For A:

You add the probabilities to get the answer to A: = .75, or 3/4

Note that the probability of ALL THREE of them hitting would be 1/3 x 1/4 x 1/5.

For B:

2/3 and 3/4 is the probability of the other two people MISSING (the remainder of 1/3, 1/4)

1.0 = 100% chance to hit the target, so 1.0 x 2/3 x 3/4 = 1/2

Mark's chance of hitting is 1/5, so do 1/2 x 1/5, = 1/10

.12 divided by 7.15 please put step by step thank you
wel

Answer:

59.58333

Step-by-step explanation:

715/12

write in long division format ( which u did )

divide 71 by 12 to get 5

multiply 71 by 12 = 5

subtract 60 by 71

bring down the next number

115/12 =9

multiply 12 by 9

subtract 180 by 115

add a decimal on the top and bring down zero

divide 70 by 12 = 5

multiply 5 by 12

subtract 60 - 70

bring down a zero

divide 100 by 12 = 8

multiply 12 by 8

subtract 96 by 100

bring down zero

divide 40 by 12 = 3

anddd u get the point

sorry it took so long

Scott burned 20 calories per minute jogging for x minutes and 5 calories per minute for biking for y minutes. He spent a total o
stiv31 [10]

Answer:

x = 112

Step-by-step explanation:

We can create two equations 1. one that calculates calories burned and 2.another that calculates minutes:

20*x + 5*y = 1200

x + y = 120

Then we can solve for x

x = 120 - y

then we can plug that into the top equation:

20(120 - y) + 5y = 1200

divide by 5:

4(120 - y) + y = 240

distribute:

480 - 4y + y = 240

and then do all that combining like factors what not and simplify and solve:

480 - 3y = 240

-3y = -240

y = 8

NOW WE CAN JUST PLUG IN THE ANSWER FOR Y TO FIND X

8+x =120

x = 112

The capacity of the milk pitcher on the counter is 9/10 liter each one pitcher has3/8 of milk in it and the other pitcher has 5/
KatRina [158]

Answer:

57/80L

Step-by-step explanation:

Given that the capacity (i.e maximum possible volume) of a pitcher is 9/10L

1st Pitcher is 3/8 full of milk

Hence Vol of milk in 1st pitcher = 9/10 x 3/8 = 27/80L

2nd Pitcher is 5/12 full of milk

Hence Vol of milk in 2nd pitcher = 9/10 x 5/12 = 3/8 = 30/80L

Total volume = 27/80 + 30/80 = 57/80L

Pentagon ABCDE and pentagon A'B'C'D'E' are shown on the coordinate plane below:
Ivan
Answer: translated according to the rule <span>(x, y) →(x + 8, y + 2) and reflected across the x-axis

Reasoning:

</span>1) The translation options are x + 8 or x + 2 and y + 2 or y + 8.

That means that the points are translated to the right and upward.

2) Then, you need to rotate the figure over the x-axis to translate it to the fourth quadrant.

To find the answer you can choose just one point to verify the rule.

3) Using the point D (-2,2) which is translated to D' (6, - 4) and knowing that the rotation over the x-axis keeps the x-coordinate unchanged while the y-coordinate is transformed into its negative, you can conclude that

3a) first the point was translated 8 units to the right and two units upward this is to a poin with x-coordinate  -2 + 8 = 6 and y-coordinate 2 + 2 = 4

3b) second the point was reflected over the x -axis keeping the same x-coordinate  x = 6 and transforming the y-coordinate into y = - 4.

So, the rule has been discovered: (x, y) →(x + 8, y + 2) and reflected across the x-axis
