Answer:
a) Monica's error was she used the formula = Base × Height
This formula is wrong formula
b) The unit for area of a triangle is square inches not inches
Step-by-step explanation:
Monica has a triangular piece of fabric. The height of the triangle is 15 inches and the triangle's base is 10 inches. Monica says that the area of the fabric is 150 inches. What error did Monica make
The area of a triangle is = 1/2 × Base × Height
From the question
Base = 10 inches
Height = 15 inches
Area of the triangular fabric = 1/2 × 10 × 15
= 75 square inches
a) Monica's error was she used the formula = Base × Height
This formula is wrong formula
b) The unit for area of a triangle is square inches not inches
Answer:
12.25
Step-by-step explanation:
49 divided by 4 = 12.25
Checking answer
12.25 • 4 = 49
X + y = 2
Substitute x + 8 into y
x + x + 8 = 2
2x + 8 =2
(Subtract 8 from both sides)
2x = -6
(Divide both sides by 2)
x = -3
Subsitute x = -3 into either equation to find y
x + y = 2
-3 + y = 2
(Add 3 to both sides)
y = 2 + 3
y = 5
Or y can be solved for using:
y = x + 8
y = -3 + 8
y = 5
Answer:
The average score is 73
Step-by-step explanation:
Your average score is the sum of each of your tests scores multiplied by the weight of the test.
We have that:
You scored 90 on the midterm
The midterm is worth 30%
You scored 60 on the final
The final is worth 50%
You scored 80 on the class project
The class project is 20%
Average score:
A = 90*0.3 + 60*0.5 + 80*0.2 = 73
The expression m over 5 would represent the number of miles the bicyclist had traveled for a time of 5 minutes. This value is a value of speed. It is the magnitude of a velocity. It represents the total distance that is traveled for given certain period of time. It is a scalar quantity since it does not have any direction. It would have dimensions of distance per time with SI units of meter per second. Other units used are kilometer per hour and miles per hour. The vector quantity counterpart of this is called the velocity where it contains the magnitude of the speed and a direction. The direction of velocity is indicated by a positive and a negative sign.
