Monica has a triangular piece of fabric. The height of the triangle is 21 inches and the triangle's base is 12 inches. Monica says that the area of the fabric is 252 in2. What error did Monica make? Explain your answer by entering the correct area of the fabric.
Answers
Answer:
She didnt divide the product of the base and height by 2
Step-by-step explanation:
The correct answer would be 126 inches squared
To find the area of a triangle you have to multiply the base and height together and then divided the product by two
The formula is A=b•h/2

A 30 foot ladder is set against the side of a house so that it reaches up 24 feet. If Alexander grabs the ladder at its base and pulls it 10 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 14 ft.) Round to the nearest tenth of a foot.
Answers
Answer:
The answer would be 10.8
Step-by-step explanation:
By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).
Hope this helps :)
The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The ladder is making a right-angle triangle with a wall as shown below.
By Pythagoras's theorem,
x² = 30² - 24²
x = 18
By Pythagoras's theorem,
y² = 30² - (18 + 10)²
y = 10.77 feet
Hence "The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet".

If a die cast rally car drove 81 meters per second, how long did it take for it to go 90 meters. Round your answer to the nearest HUNDREDTH.
Answers
Answer:
The car took 1.11 seconds to go 90 meters.
Step-by-step explanation:
Set up an equation:
Variable x = number of seconds to travel 90 meters
81 meters/1 second = 90 meters/x seconds
Take out the variables for now to focus on calculations:
81/1 = 90/x
Cross multiply:
81 × x = 1 × 90
81x = 90
Divide both sides by 81:
x = 1.111111111... seconds
Round to nearest hundredth (hundredth is the second decimal place):
x = 1.11
