According to the Pythagorean theorem, the square of the hypotenuse (the longest side) of a right-angled triangle equals to the sum of the squares of the other two sides. In this case, the ladder is the hypotenuse, which equals to the distance between the bottom of the ladder and the tree + the distance we want to find (x):
5² + x² = 13²
25 + x² = 169
x² = 144
x = √144 = 12.
The distance between the ground and the top of the ladder is 12 ft.
Answer:
c. quadrilateral
Step-by-step explanation:
All of the sides are different lengths, so the quadrilateral cannot be a parallelogram, rhombus, or square.
Its best descriptor is <em>parallelogram</em>.
_____
A <em>parallelogram</em> has opposite sides parallel and congruent. A <em>rhombus</em> also has adjacent sides congruent. A <em>square</em> is a special case of rhombus in which the corner angles are right angles.
I could help if I had a picture of the problem
Answer:
$2.5
Step-by-step explanation:
Number of pounds of banana needed = 5 pounds
Cost per pound of banana = 0.50
To solve using place value blocks :
Ignoring the decimal in the cost per pound:
We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.
5 * 5 = $25
Now we can add the one decimal point (in the cost per pound) to our result
Then we have $2.5
Hence, total cost = $2.5
The nearest whole number would be 96
