HURRY HELP! ILL MARK BRAINLEST ANSWER!!! if I have an 82 in a class, and I get 100 on two projects worth 15% of my grade, what w
dsp73

Answer:

Your final grade would be 87.4

Step-by-step explanation:

When an assessment is worth a certain percentage of a final grade, the grade percentage of the assessment is taken from its allocated percentage of the final grade. For example:

One project is worth 15% of the final grade, and you got 100% on it. This means that the percentage it contributes to the final grade is 100% (achieved) of 15% (allocated %). 100% of 15% is 15% (15x1). This means that if you hypothetically only completed the project 100% without other assessments, your final grade would be 15%.

This is the same for the other project: 100% (achieved) of 15 (% worth of final grade) = 15.

This is because when you get 100% on the project, you get the full 15% of its worth for the final grade (if that makes sense).

So, from both projects, the final grade would be 30.

Now for the 82.

Since the projects together are worth 30% of the final grade, it means that the 82 in class is worth the remaining 70%.

82% (achieved) of 70 (worth %) = 70x0.82 = 57.4

The 82 in class contributes 57.4 towards the final grade.

Since we have 30 from the projects, and the 57.4 from the class, your final grade would be 30+57.4 = 87.4

Hope this helped!

line c passes through the origin and has a slope of -7.Write an equation like y=mx+b.If theres enough information if not explain
Pavel [41]
If you have a picture that shows line c on a graph, you could find your y-intercept or b. If not, you need the y-intercept to make an equation.

Suppose he makes two stops of 10 minutes each during his journey. Will he be
poizon [28]

Answer:

No, he would not be able to reach the town in 4 hours with two 10 minutes stops and same speed

Completed question;

Max travels to see his brother's family by car. He drives 216 miles in 4 hours. What is his rate in miles per hour? Suppose he makes two stops of 10 minutes each during his journey. Will he be able to reach the town in 4 hours if he keeps the speed the same?

Step-by-step explanation:

Average speed = total distance travelled/time taken

Given;

Total distance travelled= 216 miles

Total time taken = 4 hours

Average speed v = 216/4 = 54 miles per hour

v = 54 mph

Suppose he makes two stops of 10 minutes each during his journey.

Total time on stops = 2 × 10 = 20 minutes = 0.33 hours

Total time spent on motion = 4 - 0.33 hours = 3.67 hours

Total distance covered in 4 hours with two stops;

d = 3.67 × 54 mph = 198.18 miles

Since d < 216 miles

No, he would not be able to reach the town in 4 hours with two 10 minutes stops and same speed

What is the equation that is perpendicular to the line y=2x-3 and passes through the point (-6,5)? Show all of your work.
Helga [31]

Answer:

y = m x + b    equation for a straight line

m m' = -1    for perpendicular lines

Thus m' = -1/2    is required

Check:

-1/2 * -6 + 2 = = 3 + 2 = 5 = y    for the last equation give
