Answer: She had added the Denominator, instead of finding the LCM.

Explanation: She should've multiplied them by a common number to equal a common Product, and replace the Denominator with the Product. (The correct denominator is 20, because 4 x 5 = 20, and 5 x 4= 20)

10,101 base 2 + 11,011 base 2 =
REY [17]

Answer:

110,000 base 2

Step-by-step explanation:

column 1 [the first position in the number]:

1+1=0, (carry 1<u>)</u>

column 2:

0+1 +<u>1</u> <em>(carried)</em>=0, (carry 1)

column 3:

1+0+<u>1</u><em> (carried)</em>=0, (carry 1)

column 4:

0+1+1 <em>(carried)</em>=0, (carry 1)

column 5:

1+1+1=1, (carry 1)

then you write the last 1 'cause there is n number to add with:

10,101_{2}+11,011_{2}=110,000_{2}

In binary system the highest number to write is 1, if you add 1+1, it jumps to 0, and you have to carry 1 to the next position.

If you are not sure about the sum, you can convert the numbers in base 2, to base 10, so you can know if it is correct:

10,101_{2}=21_{10}\\11,011_{2}=27_{10}\\110,000_{2}=48_{10}

So 21+27=48.

<em>In decimal system when you add 9+1, it jumps to 0 and then you have to carry 1 to the next position, because the the highest number you can write is 9.</em>

Graph the inequality y&gt;2/3x-1
xenn [34]

Answer:

graph{y>2/3x-1 [-10, 10, -5, 5]}

Explanation:

First, graph a line with the equation y=23x−1. This equation is in the form y=mx+b. 23 is the slope and −1 is the y-intercept.

graph{2/3x-1 [-10, 10, -5, 5]}

However, we are graphing an inequality so we're gonna have to shade either the area above the line or below the line. First, let's look at the inequality symbols.

> Greater than

< Less than

≥ Greater than or equal to

≤ Less than or equal to

If the inequality includes equal to, then the line will be solid. If not, then the line will be dotted. Since the inequality y>23x−1 doesn't contain the equal to, the line will be dotted.

The direction of the inequality sign matters too. If it's greater than, then the top area will be shaded. If it's less than, then the bottom area will be shaded. Since the inequality y>23x−1 has greater than, the top area will be shaded.

graph{y>2/3x-1 [-10, 10, -5, 5]}

Calculate the total surface area of a rectangular box 10cm long, 8cm wide and 6cm tall.<br>​
kicyunya [14]

Answer:

The answer is

<h2>376 cm²</h2>

Step-by-step explanation:

Since the rectangular box is a cuboid,

Total surface area of a cuboid is given by

<h3>2( lw + wh + lh)</h3>

Where

l is the length

w is the width

h is the height

From the question

l = 10 cm

w = 8cm

h = 6cm

Substitute the values into the above formula

That's

Total surface area of the rectangular box is

2 [ (10)(8) + (8)(6) + (10)(6) ]

2 [ 80 + 48 + 60 ]

2( 188)

We have the final answer as

<h3>Total surface area = 376 cm²</h3>

Hope this helps you

What is the slope of the line that passes through the points (0,5) (2,10)
Nadya [2.5K]

Answer:

m=5/2

Step-by-step explanation:

the equation of slope is (y2-y1)/(x2-x1)

here are the points given: (0,5), (2,10)

let's label the points:

x1=0

y1=5

x2=2

y2=10

now substitute into the equation (m is the slope)

m=(10-5)/(2-0)

subtract

m=5/2

the slope is 5/2
