Answer:
22
Step-by-step explanation:
In this sequence, the next number is found by adding 4.
M=Y2-Y1/X2-X1
M= 1250-1625/4-2.5
M=841.25
But I have no clue how you would graph that
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
Part A) The area of a parallelogram is base × height.
3 × 2/3 = 6/3 = 2
2 feet squared is the area of the whole parallelogram.
Part B) The diagonal of a parallelogram separates it into two congruent triangles.
The area of each triangle will be:
base × height × 1/2
3 × 2/3 × 1/2 = 6/6 = 1
1 foot squared is the area for each triangle.
