A soccer player practices kicking the ball into the goal from halfway down the soccer field. The time it takes for the ball to get to the goal from the time it is kicked averages about three seconds. The soccer field is 90 meters long. The player wants to know the average velocity of the ball.

Is there enough information to calculate this?


A: No, only average speed can be calculated from the distance of 90 meters and the time of three seconds.

B: No, only average speed can be calculated from the distance of 45 meters and the time of three seconds.

C: Yes, displacement is 45 meters, elapsed time is three seconds, and the direction is toward the goal.

using the definition of multiplication to explain why a box that is 5 inches high 4 inches wide and 3 inches long has a volume of 5• (3•4) cubic inches explain the parentheses in the expression 5•(3•4)

Answers

Given:

Height of box = 5 inches

Breadth (width) of box = 4 inches

Length of box = 3 inches

Volume of box = 5 • (3 • 4) cubic inches

To find:

The explanation for the parentheses in the expression 5•(3•4)

Solution:

We know that,

Volume of a box is

[tex]Volume = length \times breadth \times height[/tex]

Area of a rectangle is

[tex]Area = length \times width[/tex]

Now,

Volume of box = 5 • (3 • 4) cubic inches

In this expression, (3 • 4) represents the product of length and with of the box. So, it means represents area of the base of box and after multiplying the base area with height we get the volume of the box.

Therefore, the parentheses in the expression 5•(3•4) represents the base area of the box.

Part C: Using the relation in Part B, what is the value of x if f(x) - 40? (5 points)
(10 points)

Answers

Answer:

  A) is a function

  B) f(x) is greater

  C) x = 12

Step-by-step explanation:

A) Yes, the relation is a function.

A function has a unique input value for each output value. There are no repeated x-values, so this relation is a function.

__

B) The table says y=6 for x=6.

  f(6) = 2(6)+16 = 28

f(x) has a greater value for x=6.

__

C) Substituting the given information, we have ...

  40 = 2x +16

  24 = 2x

  12 = x

The value of x is 12 when f(x) is 40.

Brad has groups of 10 pennies. Brad counts 40, but he has 6 more stacks to count. How many pennies does he have? Explain your answer to a family member or friend

Answers

Answer:

100 pennies

Step-by-step explanation:

each stack is 10 pennies. brad has 4 stacks which equal 40 and has 6 more stack which qual 60. 40+60=100

The number of pennies he has is 100 pennies.

Given,

Brad has groups of 10 pennies.

Brad counts 40, but he has 6 more stacks to count.

We need to find how many pennies he has.

How do we find the total number of given groups?

If each group has 20 items the total number of items for M groups is:

= M x 20

We multiply the total number of groups with the number of items in each group.

We have,

1 group = 10 pennies

Brad counts 40 and 6 more stacks to go.

This means 4 groups have been counted.

= 4 x 10

= 40 pennies

Now 6 more stacks:

= 6 x 10

= 60 pennies

Now,

Total number of pennies:

= 40 + 60

= 100 pennies

Thus the number of pennies he has is 100 pennies.

Maggie's brother is 4 years younger than four times her age. The sum of their ages is 31.
How old is Maggie?

Answers

just multiply ten times four and you’ll get ur answer.
First, determine the terms.
For Maggie, let’s use the variable m.
For her brother, it is (4m-4).
Their ages together is 31.

Let’s combine to make an equation:
(4m-4)+m=31
First, combine like terms on the left
5m-4=31
To begin isolating m, add 4 to both sides
5m-4=31
+4 +4
—————-
5m=35
To completely isolate m, divide both sides by 5.
5m=35
—— —-
5 5
From here, you get
m=7

You can check by putting this into the original equation.
(4(7)-4)+7=31
(28-4)+7=31
24+7=31
31=31

Therefore, Maggie is 7 years old.

Henry sends his hawk with a message to his uncle. The hawk flies out against the wind and returns with the wind, spending 3 hours on the whole trip. How far is Henry's uncle from Henry if the speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather?

Answers

Answer:

Distance between Henry and his uncle is 74.25km.

Step-by-step explanation:

Speed of Hawk with wind = 50+5

                                           =55km/hr

Speed of Hawk against wind = 50-5

                                               =45km/hr

we know that ,

        [tex]Distance = speed \times time[/tex]

Let the distance between Henry and uncle is d,

According to the question ,

[tex]\frac{d}{55} + \frac{d}{45} = 3[/tex]

[tex]\frac{9d + 11d}{495} =3[/tex]

[tex]20d = 3\times 495[/tex]

[tex]d =\frac{3\times495}{20}[/tex]

d= 74.25km

Hence , the answer is 74.25km

The relation between speed, time, and distance is used. Then the distance between Henry's uncle from Henry is 74.25 miles.

What is speed?

The distance covered in an hour is called speed. it is a scalar quantity.

What is relative speed?

The concept of relative speed is used when two or more bodies moving with some speed are considered.

Henry sends his hawk with a message to his uncle.

The hawk flies out against the wind and returns with the wind, spending 3 hours on the whole trip.

We know the relation

[tex]\rm speed = \dfrac{distance }{time}[/tex]

Let the distance between Henry's uncle from Henry be x.

The time of the trip is during the traveling remains constant. That is

[tex]\rm T = T_1 + T_2\\\\T = \dfrac{x}{v_1} + \dfrac{x}{v_2}[/tex]

The speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather. Then we have

[tex]\rm v_1 = 50 - 5 = 45\\\\v_2 = 50 + 5 = 55[/tex]

Then

[tex]\begin{aligned} \rm \dfrac{x}{45} + \dfrac{x}{55} &= 3\\\\\rm \dfrac{9x + 11x }{495} &= 3\\\\\rm 9x + 11x &= 1485\\\\\rm 20x &= 1485\\\\\rm x &= 74.25 \end{aligned}[/tex]

Thus, the distance between Henry's uncle from Henry is 74.25 miles.
