Answer:
4 questions
Step-by-step explanation:
90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:
0.9x = 36
x = 40
She must have gotten 40 - 36, or 4 questions wrong.
Answer:
yes
Step-by-step explanation:
Slope intercept form is y=mx+b
m=slope
b=y-intercept
the slope is the rate of change of the graph, basically rise/run (change in y divided by change in x)
the y intercept is where the graph intercepts the y axis
we usually use this form because we can find the slope and find where it hits the y axis.
there are other forms that may be helpful later on, but this one is usually the easiest form to find from a graph
<span>The <u>correct answer</u> is:
$31.40.
Explanation<span>:
Since 6 oranges cost $3.00, we can divide to find the cost of one orange:
3.00/6 = $0.50. Each orange costs $0.50.
If ten oranges are bought, this would cost 10(0.50)=$5.00.
Each grapefruit costs $2.40; 11 of them would cost 11(2.40) = 26.40.
Together the total cost is $5+$26.40 = $31.40.</span></span>
Answer: 11.25 secs
Step-by-step explanation:
So in this sense the rockets origin or the ground is modeled at h=0 so the time required if used on a table shows that h=0 between the values of 11 and 12. So if you plug and chug decimal values between these two values you get exactly 0 at t=11.25 so it takes approximately 11.25 seconds for the rocket to return to the ground
