Answer:
7 cm
Step-by-step explanation:
The formula for finding the area of a square is A = a^2 (where a is the side length).
So let's substitute the given values in.
49 = a^2
a = sqrt(49)
a = 7 cm <--- This is our answer
Hope this helps!
Answer:
There are 2 ways of righting this:
Method 1: height is 15 feet below ground level
Method 2: height is -15 feet ( a negative value )
Step-by-step explanation:
Drawing a sketch helps in understanding the question:
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Distance of travel is more than height above ground. So it ends up below ground (presume in a cut out).
Distance below ground is
105−90=15 feet
Answer:
- <em>Tangent segments from a common external point are</em> <u>congruent</u>
Explanation:
A <em>tangent</em> line to a circle is a line that touches the circle in only one point of the cirfumference, and, hence, the tangent is perpendicular to (forms a right angle with) the radius of the circle.
There are many thorems relative fo the tangent lines of a cirle.
One of those theorems states that if two tangent lines to a circle are drawn from a same external point, the two segments formed from the coomon external point to the tangency points have the same length.
Also, you must know that, from the definition, two segments of the same length are known as congruent segments.
Therefore, calling P the common external point, A one point of tangency in the circle, and B the other point of tangency, then:
- length segment PA = length segment PB.
- So, the two <u><em>tangent segments from an common enternal point are congruent.</em></u>
Answer: 125
Step-by-step explanation:
5^3=5*5*5=125
Answer:
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
so
The distance is equal to multiply the speed by the time
we have
Convert mixed number to an improper fraction
substitute
Convert to mixed number
