Answer:
He must use 3 GB or less
Step-by-step explanation:
Total cost = flat fee + number of GB * charge per GB
We know he must stay under 30 dollars so change the equals to less than or equal to (the opening facing the 30) and replace the total cost with 30
30≥ flat fee + number of GB * charge per GB
We know the flat fee is 21 and the charge per GB is 3
30≥ 21 + number of GB * 3
Subtract 21 from each side
30-21 ≥ 21-21 + number of GB * 3
9≥number of GB * 3
Divide by 3
9/3 ≥ number of GB * 3/3
3≥ number of GB
He must use 3 GB or less
Answer: C) 8 cm
Step-by-step explanation:
Given: In △ABC AB=8 cm , m∠A=70° , and m∠B=55° .
The angle sum property of triangle says that the sum of all interior angles in a triangle is equals to 180°.
⇒ m∠A+m∠B+m∠C=180°
⇒70°+55°+m∠C=180°
⇒m∠C=180°-125°
⇒m∠C=55°
Now, in △ABC m∠C= m∠B= 55°
⇒AB=AC [∵ Sides opposite to equal angles of a triangle are equal]
⇒ AC= 8 cm.
Answer:
Observe the attached image
Step-by-step explanation:
The limit of inequality is marked by the equation of the line
Therefore the first step to graph the inequality is to graph the line
First we find its cut point with the x axis. (y = 0)
Second we find its cut point with the y axis. (x = 0)
Now that we know the cut points, we can graph the line.
Then, the inequality
it tells us that the region is made up of all the values of y that are smaller or that are below the equation of the line .
In this way we shadow the region that is below the line and this will be the graph of the inequality. Observe the attached image
30 days, hath September. April June, and November. All the rest have 31, except for February, which has 28. And 29 on a leap year.
So we need to find the unit rate (the denominator is 1). Divide 18 by 3 to find the amount of miles in 1 day. 18/3=6. So m=6d. To find the number of miles in 10 days, you can make an equation 1/6=10/x. x=60, so the number of miles Henry will bike in 10 days is 60 miles. Repeat with the second chart
