What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
The question is incomplete, and the upper part of the completed question is:
"The base of a solid oblique pyramid is an equilateral triangle with an edge length of 5 units. A solid oblique pyramid has an equilateral triangle base with an edge length of 5 units. "
The diagram of the base of the considered pyramid is attached below.
The perpendicular from A to BC is touching BC at C, and is bisecting it (it can be proved).
Consider the triangle ADB. It is a right angled triangle.
We need the length of AD which represents the height of the triangle ABC.
This is obtained using Pythagoras theorem as:
[tex]|AB|^2 = |AD|^2 + |DB|^2\\\\|AD|^2 = |AB|^2 - |DB|^2\\\\|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}[/tex]
(took positive root because of |AD| being length, which is a non-negative quantity).
SImplifying it, we get:
[tex]|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}\\\\|AD| = \sqrt{\dfrac{5^2(4-1)}{4}} = \dfrac{5\sqrt{3}}{2} = \dfrac{5}{2} \times \sqrt{3} \: \rm units[/tex]
Thus, the expression that represents the height of the triangular base of the pyramid is given by: Option B: (5/2)√3 untis

A bag contains 5 blue marbles, 2 green marbles, and 3 yellow marbles. What is the probability of choosing one green marble and then a yellow marble with replacement? 3/50 1/15 1/2 6/10
Answer:
Step-by-step explanation:
Total number of marbles = 5 + 2 + 3 = 10
Probability of choosing 1 green marble = 2/10
Probability of choosing 1 yellow marble = 3/10
Notice (and this is important) that the denominator didn't change. Why?
Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.
So what is the probability of P(green then yellow)?
P(green then yellow) = 3/10 * 2/10 = 6/100
Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.

2 1/2 dozen roses cost $40.50 what is the cost of a single rose
,
Answer:
$1.35
Step-by-step explanation:
=> No. of roses in a dozen = 12
=> No. of roses in half dozen = 12/2 = 6
=> No. of roses in 2 1/2 dozen = 2(12)+6 =30
=> 30 roses costs for $40.50
=> Cost of single rose = 40.5/30 = $1.35

A movie theater sells two sizes of popcorn, large and small, in bags shaped like rectangular prisms. The small bag has a height of 5.5 inches, a length of 5 inches, and a width of 3 inches. The large bag has the same width and length as the small bag, but two times the volume. What is the height of the large bag of popcorn?
the solution is:
u should at the first find the volume of the small bag that V= LWH ( Lenght, width, height)
so it will be 82.5
since the Volume of the large bag is 2 times the volume of the small bag so the volume of large bag will be 165
so H = V / LW
H = 165 / 5×3
H = 165 / 15
So the Answer is H = 11
Todd plans to swim 18 laps in the pool. Each lap is 50 yards. So far, Todd has swam 738 yards. What percentage of the total has Todd completed?

[tex]\begin{aligned}\implies \textsf{Area of a sector of a circle }& =\left(\dfrac{120^{\circ}}{360^{\circ}}\right) \pi \cdot 9^2\\ & = \dfrac13 \cdot \pi \cdot 81\\ & = 27 \pi\: \sf units^2\end{aligned}[/tex]
The area of the asked sector is 27π units².
What is a sector of a circle?A sector of a circle is a portion or part of a circle that is composed of an arc and its two radii.
Given that a circle L, we radius 9 and a central angle of 120°, we need to find the area of the sector, which is intercepted by the central angle,
So,
The area of a sector of a circle = central angle / 360° × area of the circle,
So,
A = 120°/360° × π × 9²
= 1/3π × 81
= 27π
Hence, the area of the asked sector is 27π units².
