solve for h
h=what
5 - 8h = 21
Answer:
h = -2
Step-by-step explanation:
subtract 5 from both sides (5-8h-5=21-5)
simplify (-8h=16)
divide both sides by -8 (both -8's cancel, leaving 16/-8 which is -2.)
The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird in feet per second?
Answer:
[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]
Step-by-step explanation:
Given
[tex]Altitude\ Change = -4\frac{1}{4} \ ft[/tex]
[tex]Time = 2\frac{1}{2}\ s[/tex]
Required
Determine the average change
This is calculated as follows:
[tex]Average\ Change = \frac{Altitude\ Change}{Time}[/tex]
This gives:
[tex]Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}[/tex]
[tex]Average\ Change = -4\frac{1}{4}/2\frac{1}{2}[/tex]
Convert to improper fractions
[tex]Average\ Change = -\frac{17}{4}/\frac{5}{2}[/tex]
Convert to multiplication
[tex]Average\ Change = -\frac{17}{4}*\frac{2}{5}[/tex]
[tex]Average\ Change = -\frac{17}{2}*\frac{1}{5}[/tex]
[tex]Average\ Change = -\frac{17}{10}[/tex]
[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]

Pls help due in an hour
Answer:
4) Yes
5) Yes
6) Yes
7) No
Step-by-step explanation:
4) When we look at the table in the question, we can see the pattern is comics x 3 = price.
We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.
5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.
So, this is a proportional relationship.
6) The same reasoning applies to 6, we can see they follow a pattern.
7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.

Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.
What is the standard deviation of the length of energy bars produced at Eileen's Energy Bars?
3.5
3.25
0.75
0.25
Answer:
0.25
Step-by-step explanaition:
The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $10 million after 4 years, as shown in the graph:
There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 0, negative 20 and 4, 10.
Which equation most closely represents the line depicted in the graph?
f(x) = −10x + 4
f of x equals fifteen halves times x minus 20
f(x) = 10x − 4
f of x equals two fifteenths times x minus 20
Answer:
the correct graph of this function is a graph of a line that has a y-intercept that is approximately negative $20 million and an x-intercept that is approximately 2.7 years.
Step-by-step explanation:
Answer: I believe it's D, "f of x equals two fifteenths times x minus 20" but im about to submit the test and i'll let you know if im wrong :))
Help please I added the number line.
Answer:H
Step-by-step explanation:
Because 0.25 x 9 will give you 2.25. Then add that to the original number; $3.50 + $2.25 = $5.75. Hope this helps :)
