Answer:
D
Step-by-step explanation:
as 70⁰F is s positive number it is greater than any negative number, to in order to see how far apart it is, you have to subtract the lower number from the higher number hence 70⁰F-(-225⁰F) because the 225⁰F is a negative that you are subtracting, 70⁰+225⁰F could also work, as the two negative cancel out
Answer:
Any equation with a slope greater than ²/₃
Step-by-step explanation:
Given table:
The <u>unit rate</u> is a <u>ratio</u> that compares the first quantity to one unit of the second quantity. The unit rate is also the <u>slope</u> of a linear equation.
<u>Linear equation</u>
where:
- m is the slope
- b is the y-intercept
To find the <u>slope</u>, take two <u>ordered pairs</u> from the table:
Substitute them into the <u>slope equation</u>:
Therefore, the unit rate is ²/₃.
Any equation with a slope greater than ²/₃ is an equation with a greater unit rate than that represented in the given table.
Remember that f(x) = x is a straight line heading from the lower left corner to the upper right corner. But, the graph is moved up two units, so add 2. Thus, the answer is c.
Draw a diagram and mark the three sides as x, x+10, and 2x. then form the equation 4x+10=154. solve!
Area = l*w
Area of living room rug = 12(1/2)*10(3/4) = 134.375
Total area - covered areas = areas seen
Total area - couch area - entertainment area = areas seen
134.375 - 12(1/2) - 6 = 115.875
The areas of the rug seen is thus 115.875 square feet. (sq. ft)
