To find 1520 divided by 83 with the remainder, divide 1520 by 83, which results in 18 with a remainder of 26.

The question from the student involves dividing 1520 by 83 and finding the remainder. To perform this calculation, we divide 1520 by 83. The quotient is the whole number result of the division, and the remainder is what is left over after the division.

Here's how you'd calculate it:

Divide 1520 by 83.

Find the whole number quotient, which is the number of times 83 goes into 1520 completely.

Calculate the remainder by subtracting the product of the quotient and 83 from 1520.

In this case, 1520 \\div 83 is 18 with a remainder of 14, since 83 x 18 = 1494, and 1520 - 1494 = 26. Therefore, 1520 divided by 83 equals 18 with a remainder of 26.

Answer: Our numbers are: [tex]\sqrt{8/3}[/tex],  π, 3.01245 and [tex]\sqrt{17}[/tex]. Let's analyze them:

1) [tex]\sqrt{8/3}= \sqrt{16/6} =4/\sqrt{6}[/tex] and [tex]\sqrt{6} \geq\sqrt{4}= 2[/tex], so [tex]4/\sqrt{6} \leq4/2 = 2[/tex]

So [tex]\sqrt{8/3}\leq2[/tex]

2) the number pi is 3.14159265

3) this number is 3.01245, doesn't require more analyzing-

4) [tex]\sqrt{17}[/tex], we know that [tex]\sqrt{16} = 4[/tex], then [tex]\sqrt{17} \geq 4[/tex]

So the correct order from greatest to lowest is:

[tex]\sqrt{17}[/tex], π , 3.01245, [tex]\sqrt{8/3}[/tex]

The correct question is?

What is √7/√11 in the simplest radical form?

To travel 200 meters at 5 m/s, it would take 40 seconds.

To travel 200 meters at 5 m/s, we can use the formula for speed:

speed = distance / time

5 m/s = 200 meters / time

time = 200 meters / 5 m/s = 40 seconds

Answer:

The height of the pole is 38.5 m.

Step-by-step explanation:

Given information:

The height of stop sign is [tex]h=7\rm \; ft[/tex]

Length of shadow of stop sign is [tex]l=2\rm \; ft[/tex].

The length of shadow of pole is [tex]L=11\rm \; ft[/tex].

Now, the shadow is measured at the same time for both the cases. So, the triangles formed by stop sign and its shadow, and pole and its shadow will be similar.

For similar triangles, the sides are always in same proportion.

Solve for the length of pole as,

[tex]\dfrac{H}{h}=\dfrac{L}{l}\\\dfrac{H}{7}=\dfrac{11}{2}\\H=7\times 5.5\\H=38.5[/tex]

Therefore, the height of the pole is 38.5 m.

The distance between points (10,7) and (2,7) on a coordinate plane will be 8 units.

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

It is given that, the points on the coordinate planes are (10,7) and (2,7).

(x₁,y₁) = (10,7)

(x₂,y₂) = (2,7)

The distance between points (10,7) and (2,7) on a coordinate plane is found as,

(d) = √(x₂ - x₁)² + (y₂-y₁)²

Substitute the given values as,

(d) = √(2 - 10)² + (7 - 7)²

=√(-8)² + (0)²

=√64

=8 units

Thus, the distance between points (10,7) and (2,7) on a coordinate plane will be 8 units.

Answer:

Step-by-step explanation:

Final answer:

By dividing the total distance (20.25 miles) by the total time (2.5 hours), we find that the mouse has a top speed of 8.1 mph and could therefore travel 8.1 miles in one hour if it maintained this speed.

Explanation:

To find out how far a mouse can travel in an hour at its top speed, we can use the information provided that the mouse ran 20.25 miles in 2.5 hours. This question is essentially asking us to calculate the speed of the mouse in miles per hour (mph), which is a common way to express speed. We'll use a simple division to solve this problem.

First, we divide the total distance traveled by the total time taken to find the speed:

Performing the division:

Speed = 8.1 mph

Therefore, if the mouse continued to run at its top speed, it would be able to travel 8.1 miles in one hour.

To calculate the volume in milliliters, we first convert gallons to liters (2 gallons * 3.875 liters/gallon = 7.75 liters), then convert liters to milliliters (7.75 liters * 1000 ml/liter = 7750 milliliters). So, Sarah purchased 7750 milliliters of milk.

Sarah purchased 2 gallons of milk, with each gallon approximately 3.875 liters. To convert liters to milliliters (ml), we should remember that 1 liter equals 1000 milliliters. So, to find the total amount in milliliters, we first convert gallons to liters (2 gallons * 3.875 liters/gallon = 7.75 liters), then convert liters to milliliters (7.75 liters * 1000 ml/liter = 7750 milliliters). Therefore, Sarah bought 7750 milliliters of milk.

There are different kind of speed in mathematics like average speed, instantaneous peed, to solve this question we need to know the concept of average speed. Therefore the correct option is option B

Average speed is defined as the total sum of distance divided by total sum of time

Mathematically,

Average speed  = total distance ÷total time taken

Here we have to find the percent of of Celina’s average running speed

So for this we will apply formula as

(Difference in distance ÷original distance)×100

So from question, Celina walk  4 miles in 1 hour  and can run 8 miles in 1 hour so, the the difference in distance between running and walking is 8-4= 4

So to find the percent of Celina’s average running speed is her average walking speed = (4 ÷8)=50%

Therefore, Celina’s average running speed is her average walking speed is 50%. The correct option is Option B

Interest, sales tax, and markups are all additional charges added to the original amount, but they differ in how they are calculated and when they are charged.

Interest is similar to sales tax and markups in that they all involve additional charges or fees that are added to the original amount.

Interest is the extra amount paid for borrowing money, while sales tax is the extra amount paid on the purchase of goods or services, and markups are the extra amount added to the cost price to determine the selling price. They all increase the total cost or price of the transaction.

The main difference is that interest and markups are calculated as a percentage of the original amount, while sales tax is calculated as a percentage of the purchase price. Additionally, interest and markups are typically charged over a period of time or for a specific duration, while sales tax is a one-time charge at the point of sale.

The MOST reasonable estimate of the y-intercept for this linear graph is 0.6

Option C

The y-intercept of a linear graph is the point where the line intersects the graph on the y-axis

The slope-intercept form of the equation of a line is:

y  =  mx  +   c

where m is the slope

and c is the y-intercept

Considering the graph shown, the line intersects the y-axis on the point y = 0.6

Since the line intersects the y-axis on the point y = 0.6, the most reasonable estimate of the y-intercept of the linear graph is 0.6
