Billy played in 3 baseball games with a batting average of 0.417. In the first game, he had 1 hit in 4 times at bat, and in the second game, he got 2 hits in 3 times at bat. In the third game, how many times was Billy at bat, and how many hits did he have?

Answers

1 hit in 5 times a bat
1/4 = .25
2/3 = .66
1/5 = .20
.25 + .66 + .20 = 1.16
1.16/3 = .38
This is closer than you would if you hit 2 hits in 4 times

You are creating your own real-world problem or word problem using Pythagorean Theorem. You create the problem and solve it. Use what you find to help you create your own problem. It does not have to be a really hard problem.

Answer:

A man's garden keeps getting attacked by rabbits, so he decides to put a fence around it. the garden is in the shape of a right triangle. The people who build the fence measure side a and b, side a has a length of 6 yards. Side b has a length of 8 yards. What is the total length (in yards) of fence the builders will need?

The pythag equation is:

a^2+b^2 =c^2

So, we plug in 6 for a and 8 for b and we get:

(6*6)+(8*8)=c*c

36+64=c*c

100=c*c

Now, we all know that 10*10 is 100 so:

c=10

Now we add 10 to 8 and 6 and we get:

The builders will need 24 yards of fence.

The linear function graphed below represents the height of a stalk of corn since a farmer began using a new fertilizer. What is the initial value?

A graph titled Height of a Stalk of Corn has Number of Days Using New Fertilizer on the x-axis and Height (feet) on the y-axis. Points are at (3, 10), (4, 12), (5, 14), and (6, 16).

Answers

Answer:

The initial value is 4

Step-by-step explanation:

the linear equation is 2/1 or 2. the equation is y = 2x + 4. In other words every time it rise 2 the line move the right 1. We just have to retrace our steps and since 3 - 3 = 0 we have to retrace it 3 times and 6 times on the y axis which gets us 4.

Internal Value is 4 thanks

Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an additional 0.10 per mile driven. The second plan has no initial fee but costs 0.60 per mile driven. How many miles would Alonzo need to drive for the two plans to cost the same?

Answers

Answer:

for plan B if he rides for 100 miles he will pay 60$

for plan A if he rides for 100 miles he will pay 60$

Step-by-step explanation:

the reason is that B. 100x0.60=60

and A (100x0.10)+50=60

Answer:

100 miles

Step-by-step explanation:

If Alonzo drives 0 miles, then the first plan would cost him 50 dollars and the second plan would cost him nothing.

If Alonzo drives 10 miles, then the first plan would cost him 51 dollars and the second plan would cost him 6 dollars.

From these statements, we can observe that the second plan is increasing at a rate 6 times the first one and will overtake it at one point.

Our solution is the point of intersection between these two functions - where they cost the same.

To find this, equate

0.1x + 50 = 0.6x

where x is the number of miles Alonzo drives,

multiply the equation with 10 to get,

x + 500 = 6x

subtract x,

5x = 500

and divide 5,

x = 100.

So at 100 miles, both plan 1 and 2 will cost 60$. This is our answer. Good Luck!

Joe is a scientist who works with the Department of Agriculture. In order to ensure a good harvest, Joe keeps track of various local beetle populations.

Will give brainliest, if the answer is correct OR well explaining explanation ( Either Both)

Answers

Answer:

There are 20,000 Beatles in the total population

Step-by-step explanation:

59 Beatles out of the 2,000 are marked (2.95% or 59/2000)

-----------------------------------------

1 / 0.0295 = 33.8983051

That means that the total population is 33.89 times larger than the 590 marked beatles.

33.8983051 x 590 = 20,0000 Beatles total

Answer:

Approximately 20,000 beetles

Step-by-step explanation:

The answer is approximately 20,000 beetles because Joe found 590 beetles and marked them. When he found the other 2,000 beetles, 59 of them were marked. 59 is 10% of 590. Since Joe found 2,000 beetles that must be 10% of some number. To find that number, you must multiply 2,000 by 10. So 2,000 x 10 is 20,000, so there is approximately 20,000 beetles

2 4/5−1 1/2

as a fraction

Answers

The answer is 1 3/10. This is because if we turn them into a mixed fraction we get 14/5 and 3/2. Then we find the least common denominator which is 10. So we multiply 5x2 and 14x2 to get a new fraction of 28/10 and then multiply 3x5 and 2x5 which gets us 15/10. Now that both fractions have a common denominator we can just subtract 28/10-15/10 which is 13/10 which is equal to 1 3/10.

13/10 hope this helps

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

On Friday, the number of friends Sharon called 4 friends

On Saturday, the number of each of those 4 friends called 4 different friends.

Therefore, the number of friends on Saturday = 4 × 4

= 16

The number of friends called on, Sunday = 16 × 4

= 64

Hence, the number of friends called on Sunday is; 64.

-5= -10+y how do i reorder this and why do i reorder it in that way? i think i know how to reorder it i'm just confused on why it has to be ordered that way. plz help, thanks!

Answers

Answer:

y = 5

Step-by-step explanation:

Ok so you need to move y to its own spot so either on the right or left of the equation. BUT i recommend leaving it and instead moving -10 to the other side. REMEMBER when you move a number to the other side of the equation you change its value so instead of -10 it will become +10. so you will get 10-5=y so 5=y, if you want the y to be on the other side flip them around -y=-5(since you switched them you need to make them minus, or plus if the number was originally negative) SINCE you have minuses on both sides you can cancel them out and you will be left with y=5.

Why you need to reorder:

you need to reorder to find Y there is no way you can find Y without reordering. When you are reordering remember that Y has to be by itself in one side of the equation.

Y = 5
