You can add up 754, 4 times

One way is just multiplying it vertically like
  754
x    4
---------
3016
Or multiply it by place value like
700 x 4 = 2800
50 x 4 = 200
4 x 4 = 16
Then add all the answers together

What whole number best approximates the value of x?
ivanzaharov [21]

The answer is 87

For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4

the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up

Hope this helps :)

What is the Pythagorean’s Theorem ?
mr Goodwill [35]
A^2 + b^ = c^2

c is the longest side of the triangle
a and b are the other two sides

So the given are the hypotenuse leg, and one of the other legs

So
a= ?
b= 12
c= 14

a^2+12^2=14^2

a^2+144=196
-144 -144

a^2=52

So we find the square root of 52

Which is 7.211 which you can round to 7.21 or 7.2

Which is the area of a square with one side that measures 1 foot? A. 1 square inch B. 100 square inches C. 144 square inches D.
cluponka [151]

Answer:

Option C. 144 square inches is the correct answer.

Step-by-step explanation:

We have been given a square with one side with a measurement of 1 foot and we have to calculate the area in square inches.

First we know that 1 foot of length = 12 inches on scale

Therefore side of the square is 12 inches

Now the area of the square will be = (Side×Side) = (Side)²

                                                          = (12)² = 144 square inches.

So the area of the square will be 144 square inches.

Use an algebraic equation to find the measures of the two angles described below. begin by letting x represent the degree measur
Lina20 [59]
Two angles are said to be supplement when their measure add up to 180 degrees.

Assume that the angle we are looking for is a and its supplement is s (I used s instead of x).

a + s = 180
a = 180 - s ......> equation I

We know that <span>the measure of the angle is eight times greater than its supplement.
This means that:
a = 8s ......> equation II

Substitute by equation II in equation I to get s as follows:
180 - s = 8s
180 = 9s
s = 20 degrees

Substitute in equation I to get the measure of the angle as follows:
a = 180 - s = 180 - 20 = 160 degrees

Based on these calculations:
The measure of the angle is 160 degrees
The measure of its supplement is 20 degrees</span>
