A garden has an area of ​​75 square feet. What is the closest whole number to the length of each side of the garden?
Mekhanik [1.2K]

Answer:

9 feet

Step-by-step explanation:

this is asking for one length of the sides of the garden. using key words, such as ~squared~ we can conclude that the shape of the garden is in fact a square, therefore, all sides will be equal. 9x9 would be the equation used, and even then the number is too large. all of the other options are larger therefore I don't think they are your answer.

Three adjacent angles are at a point. The ratio of the measurements is 3:4:5. The angles should add to 360.
zheka24 [161]

Answer:

90 degrees, 120 degrees and 150 degrees

Step-by-step explanation:

Given that three adjacent angles are at a point. The ratio of the measurements is 3:4:5. The angles should add to 360.

First add up all the ratio

3 + 4 + 5 = 12

For ratio 3

3/12 × 360 = 90 degree

For ratio 4

4/12 × 360 = 120 degree

For ratio 5

5/12 × 360 = 150 degree

90 + 120 + 150 = 360 degree.

The angles are therefore, 90 degrees, 120 degrees and 150 degrees

I need to calculate J and don’t know how please help me
nexus9112 [7]
K is opposite to 47 so k is also 47. I is opposite to 39 so I is also 39. You add all of those together making it 172. You then subtract it from 360.
So 47+47+39+39=172
360-172=188
188 is both j and opposite j so divide 188 by 2 and you get 94.
J=94

Which information can you read from an equation that is written in slope-intercept form?
Soloha48 [4]
The slope.

slope-intercept form is y= mx + b

Where:

mx is the slope
and b is the y-intercept.

Since the y-intercept isn’t an option, the correct answer would be slope.
