Answer:

A is correct

Step-by-step explanation:

The given graph is equation of straight line.

x-intercept: (1,0)

y-intercept: (0,1)

Equation of line:

x + y = 1

Option A: (0,1)

Put x=0 and y=1 into equation

0 + 1 = 1

   1 = 1

True

Option B: (1,1)

Put x=1 and y=1 into equation

1 + 1 = 1

   2 ≠ 1

False

Option C: (1,2)

Put x=1 and y=2 into equation

1 + 2 = 1

   3 ≠ 1

False

Option D: (1,-2)

Put x=1 and y=-2 into equation

1 - 2 = 1

   -1 ≠ 1

False

What is the volume of a right trianular prism with the dimesions of 15 11 17
Harlamova29_29 [7]

Answer:

1402.5 Cubic Units

Step-by-step explanation:

Volume of a Triangular Prism: V = \frac{1}{2}bhl

b - base

h - height

l - length  

15 is the height, 17 is the length, and 11 is the width  (assuming which is the base).

V=0.5 * (11 * 15 * 17) \\V=0.5*2085\\V=1402.5

The volume of the prism should be 1402.5 cubic units.

What is the greater faction than 11/20
Mila [183]

Answer:

Are you looking to calculate whether 2/10 is greater than 11/20? One of the most common calculations you'll make in math is to compare fractions. In this really simple guide, we'll teach you how to compare and determine if 2/10 is bigger than 11/20 and walk you through the step-by-process of how the calculation is made.

As we always do in these tutorials, let's recap and remind ourselves that the number above the fraction line is called the numerator and the number below the fraction line is called the denominator.

Depending on the math problem you want to solve, there are two methods to calculate if 2/10 is larger than 11/20:

Convert the fractions to have the same denominator

Convert the fractions to a decimal number

Let's start with the first method: converting the fractions to the same denominator. First, we'll set up 2/10 and 11/20 side by side so they are easier to see:

Converting Denominator

2

10

&

11

20

Our denominators are 10 and 20. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 10 and 20. In this case, the lowest common denominator is 20.

If we multiply the first denominator (10) by 2 we will get 20. If we multiply the second denominator (20) by 1 we will also get 20. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

2 x 2

10 x 2

11 x 1

20 x 1

This is what 2/10 and 11/20 looks like with the same denominator:

4

20

&

11

20

Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 4 is NOT greater than 11 which also means that 2/10 is NOT greater than 11/20.

Converting to Decimal

You can also compare these fractions by first converting them to decimal format. This is a lot faster than working out the lowest common denominator. All we do here is divide the numerator by the denominator for each fraction:

2/10 = 0.2

11/20 = 0.55

Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.2 is NOT greater than 0.55 which also means that 2/10 is NOT greater than 11/20.

Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!

√10 Multiple √15 is equal to
Paul [167]

\\ \sf\longmapsto \sqrt{10}\times \sqrt{15}

\\ \sf\longmapsto \sqrt{10\times 15}

\\ \sf\longmapsto \sqrt{2\times 5\times  3\times 5}

\\ \sf\longmapsto \sqrt{5\times 5\times 6}

\\ \sf\longmapsto 5\sqrt{6}

None of the above should be 4th option
