What is an arithmetic operation?

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the set of instructions given in the question,

The Time taken by earth to complete one revolution of the milky way galaxy is 200 million years.

One million is written as :

Then 200 million will be written as,

Which equation can be used to determine Craig's age?

What is Craig's age?

Answers

I’m pretty sure it’s 21

Answer:

x - 6 = 15

Craig is 21 years old

Step-by-step explanation:

x = Craig's age, 15 = Sue's age, and Sue is 6 years younger than Craig, so 15 (Sue's age) is 6 (Years) less than x (Craig's age). The equation is

x - 6 = 15

Using this, x - 6 = 15, we can add 6 to both sides to get x = 21, Craig is 21 years old

Runner #2 has the fastest pace.

Step-by-step explanation:

Runner #1's pace is 10 minutes per mile. You can see this shown in the graph where the line hits the halfway mark on the y axis at one minute, or (1,10). This is the unit rate of minutes per mile for Runner #1's speed.

Runner #2's pace is 8.5 minutes per mile. You can see this shown in the equation used to represent their speed, t=8.5d. T stands for time and d stands for distance. This means that 8.5 represents how much time it takes to travel the distance of a mile. This is the unit rate of minutes per mile for Runner #2's speed.

Runner #3's pace is 9 minutes per mile. You can see this shown in the table through division. To figure out how much time it takes to travel one mile, you need to divide the time by the distance. 18÷2=9, 36÷4=9, 54÷6=9 72÷8=9, 90÷10=9, and so on. The pattern here is that the result is all 9. This is the unit rate of minutes per mile for Runner #3's speed.

10>8.5 8.5<9

It takes Runner #2 the least amount of time to travel a mile, so Runner #2 has the fastest pace.

Hope this helps!

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

Let the distance traveled by the skier in 4 seconds = 72 m

And , let the distance traveled by the skier in 2 1/2 minutes = A

where 2 1/2 minutes = 150 seconds

Now , the proportion is

A / 150 = 72 / 4

Multiply by 150 on both sides , we get

A = ( 150 x 72 ) / 4

On simplifying , we get

A = 2,700 meters

Therefore , the value of A is 2,700 meters

Hence , the distance is 2,700 m

Select the best equation needed to solve for x; then solve for x:

A. 2x+1=33 ; x=16
B. 2x+1=33 ; x=17
C. 2x+1+33=90 ; x = 28
D. 2x+1+33=90 ; x=56

Answers

Answer:

x=28 or C

Step-by-step explanation:

The graph shows a right angle which is 90 degrees

This means that the two angles seperated by line C added together will get 90 degrees.

That means the formula will be 2x+1+33=90

With that shown we can get rid of A and B

Next step is to add 33 and 1 together

This gives us 2x+34=90

Then we will move 34 to the other side by subtracting giving us 2x=90-34

Then we will subtract 90-34 which will get us 56

The equation is now 2x=56

The last step is to devide 2 from each side

This lets us get the answer x=28

Hope this helps!

Answer: C

Step-by-step explanation: a right angle is 90 degrees

2*28 = 56, 56 + 1 = 57

57 + 33 = 90

Therefore the answer is C.

One of his inventions was a car that could operate on both water and land; this car was Batniks favorite. On water, it could float and travel at speeds up to 80 miles per hour. But on land, it could travel at speeds over 200 miles per hour. Batniks father had created this special car to help people from their island get to the mainland and other islands faster. When Batnik's father was a boy, the only method of travel from one island to another was by ferry, and the trip often took hours. People who were sick and needed medical help from the mainland would have to endure the long crossing or not go at all because of delays. Batniks father loved his homeland and wanted to ease the burden on the people, so he created the water car.When he showed the car to Batnik, Batniks father warned Batnik that the car should not be driven at the maximum speed on land or water because the engine could burst into flame. One day when his father was away, Batnik decided that he wanted to show the car to his friends. He drove it on the water, at first going only half the possible speed. Then, as his excitement grew, he increased his speed on the water and was nearing maximum speed. When he reached the land, he continued to accelerate. His exhilaration grew. Like the mythological Greek boy Icarus, who flew too close to the sun, Batnik forgot his fathers warning and pushed the gas pedal to the floor. When the car exceeded 200 miles per hour, it burst into flames.In the myth of Daedalus and Icarus, Icarus becomes enraptured by the ability to fly, defies his father's order to not fly too close to the sun, and suffers dreadful consequences as a result.How is Batniks story in "Too Fast" like that of Icarus from the Greek myth?Both stories are about boys who love to travel at great speeds.Both stories are about sons who improve their fathers inventions.Both stories are about boys who are great inventors.Both stories are about sons who suffer terrible fates after not following instructions. will mark brainliest please help!!
