Answer:

Step-by-step explanation:

The pythagorean theorem states that a^2+b^2=c^2. a and b are the shorter sides and c is the hypotenuse, or the longest side. You can tell the hypotenuse because it is opposite to the right angle.

Therefore, a=6, b=8 and c=x. You can switch a and b if you like, it doesn't really matter.

using the pythagorean thm. 6^2+8^2=x^2. You simplify the exponents and combine like terms to get x^2=100. You take the square root of both sides and get 10.

The base of a triangle exceeds the height by 7 centimeters. If the area is 400 square centimeters, find the length of the base a

zvonat [6]

Answer:

Base = 32 cm

Height = 25 cm

Step-by-step explanation:

Area of a triangle can be calculated as:

$Area = \frac{1}{2}\times Base \times Height$

We are given that the base of triangle exceeds the height by 7 cm. This can be expressed in an equation form as:

Base = Height + 7

Lets use B to represent base and H to represent height

B = H + 7

The equation of area can be stated as:

$Area=\frac{1}{2}bh\\\\ Area=\frac{1}{2}(h+7)(h)\\\\ 400=\frac{1}{2}h(h+7)\\\\ 800=h^{2}+7h\\\\ h^{2}+7h-800=0$

This is a quadratic equation which can be solved using a quadratic equation as shown below:

$h=\frac{-7+-\sqrt{49-4(1)(-800)} }{2(1)} \\\\ h=\frac{-7+-57}{2}\\\\h=-32,25$

Since the height cannot be negative, we'll consider the positive value only i.e height is equal to 25 cm.

Therefore, the length of base will be 25 + 7 = 32 cm.

(60mi / 1hr) * 12hr =
(12hr * 60mi) / 1hr because the hr and mi are being multiplied we can cancel the hrs =
12 * 60mi = 720mi

distance = speed * time
speed = distance / time
time = distance / speed
