The distance traveled after 2 hours will be 324 miles.

Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.

The table shows the average speed of the winner of a car race for different

years.

year      average speed

2005     135.17

2010      137.28

2015      161.94

2020     141.11

In order to find out how many miles the winner of the car race in 2015 traveled after 2 hours, we need to know the average speed at which they were traveling, which is given as 161.94 miles per hour. To find out how far they traveled in 2 hours, we can multiply this speed by the time, measured in hours.

So, if the average speed was 161.94 miles per hour, then the distance traveled in 2 hours is:

161.94 miles/hour × 2 hours = 323.88 miles.

Rounding up to the nearest whole number, the distance traveled after 2 hours is 324 miles.

The question seems to be incomplete the missing table has been attached below

The answer which we get after calculating from the data given is that  Larry has 15 dollars more than Lenny.

Let the amount which Lenny is having be x

then the amount which Larry is having will be (2/5)x

and on combining them it makes $35 .

Which means,  x + 2x/5 = 35

On simplifying this equation we will get ,

(7/5)x= 35   ,

multiplying both the sides by 5/7

x= (5/7)*35 = $25

Therefore , Lenny is having 4 25.

So Larry must be having ,  $(35 - 25) = $10

So , we can conclude that Lenny has more dollars. The difference is of 15 dollars.

Answer:

690.8 in^2

Step-by-step explanation:

First find the area of the three circles, by doing 3.14 r^2

With the innermost circle, 3.14 6^2 --> 113.04

With the second circle, 10 inches + 6 inches (inner circle radius), 3.14 16^2 --> 803.84.

With the outermost circle, you don't need it for the problem.

Then, we do subtraction to find the area of the shaded region, removing the "dount hole".

803.84 - 113.04 = 690.8 in^2

Answer:

x=3.5

Step-by-step explanation:

Answer:

x=sqrt(12) or 2sqrt(3)

Step-by-step explanation:

You can just use pythagorean theorem for this.

We can do 4^2+x^2=8^2

This gives us 16+x^2=64.

Simplify: x^2=48

x=sqrt(48)

Now, we can find x!

We just have to do 6^2+x^2=sqrt(48).

We get 36+x^2=48

simplify: x^2=12

Now, x=sqrt(12) or 2sqrt(3)

Solutions of a system of  an equations are given with the  values of the variables which  make all the equations true in which a solution of a system of given two linear equations is represented in  an ordered pair (x, y) as explained with example below:

An example of a system of two linear equations in an ordered pair , in order  to show the two equations that  are arranged  together to form a system of equations in an linear form .

let  , 2x + y = 7,

x- 2y = 6

A linear equation which consists of  two variables, as  2x + y = 7, has an infinite number of solutions. in which the  graph of a equation  is a line. we know that every point on the line is a required solution to the equation and every solution of an  equation is a point on the line.

To solve a system of two linear equations in an ordered pair , we want to find the values to particular  variables that are solutions to both  linear equations. In other words, we are expecting  for the ordered pairs (x, y) that make both equations valid . These type of equations are known as  solutions to a system of equations.

hence , the solutions of a system of equations are the values of the variables that make all the valid and obeyed equations are  true.  and solution of a system of two linear equations is represented always in an  ordered pair (x, y) .

Answer: 4 times

Step-by-step explanation: I got 4 times. Here's how to solve it:

Set up a proportional relationship, but first, we need to convert 10 hrs into mins:

1 hour = 60 mins

To find how many minutes are in 10 hours, we multiply 60 by 10, which equals 600.

So, therefore there are 600 mins in 10 hours. Now, we can set up our proportional relationship:

[tex]\frac{200}{60} = \frac{?}{12}[/tex]

So, if we know 12 is a factor of 60, we should divide 60 by 12, and we should get 5. So, now we do the same with the 200. We do 200 / 50, and we get 4. I hope this helps!

The number of students who will not be able to ride on the bus for the school trip is given by the equation A = 15 students

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

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

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The total number of students for the trip = 235 students

The number of buses = 5 buses

The number of students in a bus be = B

Now , each seat on the bus can occupy = 2 students

So , 22 seats can occupy = 22 x 2 students

22 seats in the bus can occupy = 44 students

So , the number of students in a bus B = 44 students

And , the total number of students in 5 buses = 5 x number of students in a bus B

Substituting the values in the equation , we get

The total number of students in 5 buses = 5 x 44

The total number of students in 5 buses = 220 students

So , the remaining number of students A = total number of students for the trip - total number of students in 5 buses

Substituting the values in the equation , we get

The remaining number of students A = 235 - 220

The remaining number of students A = 15 students

Therefore , the value of A is 15 students

Hence , the number of students is 15 students

As a professional artist and judging from the current sales ratio and commission rates, one would earn more if one apprenticed for Sara.

As evident in the task content; the current ratio of Sara's sales to Ravi's sale is 100 : 2.

Since Sara's pieces of art sell for $25, the total earnings is; 25 × 100 = $2500.

Hence, since the commission rate is 60%, it follows that the commission earned on sales of Sara's pieces is; 60% of 2500 = 0.6 × 2500 = $1500.

Also, since Ravi's pieces each cost $2000, it follows that for 2 pieces, the total earnings is; 2 × $2000 = $4,000.

Hence, since the commission rate for Ravi's pieces is 25%, the commission earned is therefore; 25% of 4000 = 0.25 × 4000 = $1000.

On this note, one would earn more if one apprenticed for Sara.

Area = 1/2*base*height = 1/2*9*4 = 18 sq.m

Solution:

We will be using the area of rectangle formula to calculate the areas of the three rectangles given.

(a) Length(l) = 9 m and Breadth(b) = 6 m

Area of rectangle = l × b

= 9 × 6

= 54 m2

(b) Length(l) = 17 m and Breadth(b) = 3 m

Area of rectangle = l × b

= 17 × 3

= 51 m2

(c) Length(l) = 4 m and Breadth(b) = 14 m

Area of rectangle = l × b

= 4 × 14

= 56 m2

Therefore, the area of the rectangle with the dimensions 4m and 14m having an area of 56 m2 that is (c) has the largest area whereas, the area of the rectangle with dimensions 17m and 3m having an area of 51 m2 that is (b) has the smallest area.
