Francisco wrote the number 3 × 10² in

Mathematics

Answer:

Francisco turned 3 into 3^2. I know this because 10^2 = 100 and Francisco multiplied 10^2 by 3.

10^2 = 100

100 * 3 = 300

In order for 300 to get to 900, the 3 would have had to have been squared.

3^2 = 9

3^2 * 10^2 = 900

In other words, he got the exponent for 3 wrong.

Answer:

Step-by-step explanation:

Francisco mistakenly multiplied 10² by 3². So, he got 100*9=900

Correct answer is: 3 * 10²  = 3 * 100 = 300

Leona [35]

Given:

The inequality is:

y>5x+3

To find:

The y-intercept, slope and type of line (solid or dotted).

Solution:

The slope intercept form of a line is:

y=mx+b            ...(i)

Where, m is the slope and b is the y-intercept.

We have,

y>5x+3

The relation equation is:

y=5x+3             ...(ii)

On comparing (i) and (ii), we get

m=5

b=3

It means the slope is 5 and the y-intercept is 3.

The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.

Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.

Can someone pls help me find what is 1/10+12/20?
irga5000 [103]

Answer:

\frac{7}{10}

Step-by-step explanation:

\frac{1}{10} can also be written as \frac{2}{20}

\frac{2}{20} +\frac{12}{20} =\frac{14}{20}

Simply to \frac{7}{10}

-OTHER METHOD-

\frac{12}{20} can be simplified to \frac{6}{10}

\frac{1}{10} +\frac{6}{10} =\frac{7}{10}

a box of crackers has a volume of 48 cubic inches. what is the volume of a similar box that is smaller by a scale factor of 2/3
earnstyle [38]
For this case what you need to know is that the original volume of the cookie box is:
 V = (w) * (l) * (h)
 Where,
 w: width
 l: long
 h: height.
 We have then:
 V = (w) * (l) * (h) = 48 in ^ 3
 The volume of a similar box is:
 V = (w * (2/3)) * (l * (2/3)) * (h * (2/3))
 We rewrite:
 V = ((w) * (l) * (h)) * ((2/3) * (2/3) * (2/3))
 V = (w) * (l) * (h) * ((2/3) ^ 3)
 V = 48 * ((2/3) ^ 3)
 V = 14.22222222 in ^ 3
 Answer:
 the volume of a similar box that is smaller by a scale factor of 2/3 is:
 V = 14.22222222 in ^ 3
