Answer:
0, 8, 16, 24, 32
Step-by-step explanation:
plug in the values given for x into the 8x+8 equation
Example:
8(-1)+8
8(0)+8
In this modern space age in which we live, we'll need to be careful.
2 kilograms weighs 4.409 pounds on Earth. If that much
costs $3.20, then the cost for 4 pounds is
(4 / 4.09) x (3.20) = $2.90 .
But what if you grow up to live or work on the Moon ?
2 kilograms weighs only 0.73 pounds on the Moon. If that much
costs $3.20, then the cost for 4 pounds up there is
(4 / 0.73) x (3.20) = $17.54 .
The thing to remember is that if you make frequent trips between
the Earth and the Moon, make sure you buy stuff by mass, not by
weight. The weight changes when you take it somewhere else,
and you don't want to get cheated.
Answer:
Pythagorean Theorem: c2 = a2 + b2
Find the area by adding the areas of the three triangles. The area of a right triangle is: A = ½bh
Two triangles are identical so you can just multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab.
The total area of the trapezoid is : A1 + A2 = ab + ½c2
You multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2
You subtract out the 2ab: a2 + b2 = c2.
Then what is left is the proof: a2 + b2 = c2
Answer:
a. Ordinal
b. 66.67%
Step-by-step explanation:
a. Classifying students by grade year is a way of grouping them in order even though the quantitative difference between groups is unknown. This is an example of an Ordinal level of measurement.
b. There are 14 freshmen and 18 sophomore out of the 48 students. The percentage of students that are either freshmen or sophomore is:
