Answer:
Look Down
Step-by-step explanation:
45-45-90 theorem states that x=y
so since x is equalt to why hypotanuse is x*sqrt2
4/sqrt2 is the answer of x any y
The probability will be 0.32
Step-by-step explanation:
Find the area of the shaded region
Area of a triangle is given by = 1/2 product of base and height of the triangle
Area of a triangle= 1/2*b*h where b is base length and h is height of the triangle
A=1/2*4*4 *2 =16 cm²
Area of the circle = π×r² where r is radius=4 cm and π =3.14
Area of the circle= π × 4×4 =16π =50.24 cm²
The probability that a randomly selected point within the circle falls in the red shaded area will be : P(area of shaded part/area of circle)
p=16/50.24 =0.31847133758
p=0.32 (rounded to the nearest hundredth)

Answer:
40 metre
Step-by-step explanation:
Given:
height =4 meters
area = 20 square meters
Area of a right triangle can be calculated using the expression below
1/2 b × h
Then substitute the given values
Area of a right triangle= 1/2 × 4 × 20
= 40 metre
Hence, the length of the base of a right triangle is 40 metre
Answer:
It'll take him 1/4 hours to decorate the two signs.
Step-by-step explanation:
In order to know how long Roberto will take to decorate all the signs we need to find their surface area, since they're rectangular their area is given by the product of their dimensions.
First sign:
area1 = (2/3)*(1/4) = 2/12 = 1/6 foot²
Second sign:
area2 = (1/2)*(1/3) = 1/6 foot²
The total area he has to paint is the sum of their individual areas, so we have:
total area = area1 + area2 = 1/6 + 1/6 = 2/6 = 1/3 foot²
To find out how long he'll take to decorate this area we can use a rule of three as shown bellow:
3/4 hour -> 1 foot²
x hour -> 1/3 foot²
x = (3/4)*(1/3) = 1/4 hours
