On three 150-point geography tests, you earned grades of 88%, 94%, and 90%. the final test is worth 250 points. what percent do you need on the final to earn 93% of the total points on all tests?

You must earn 243 points to have earned 93% of all possible points.

We first multiply each percentage on the previous tests by 150:

0.88*150 = 132

0.94*150 = 141

0.9*150 = 135

The total number of points possible is given by adding up the possible points for the three previous tests and the 250 for the last test:

150+150+150+250 = 700

93% of the 700 points would be 0.93(700) = 651 points.

Now we have 132+141+135+x (last test) = 651

408 + x = 651

Subtract 408 from both sides:

408+x-408 = 651-408

x = 243

Step-by-step explanation:

You must earn 243 points to have earned 93% of all possible points.

We first multiply each percentage on the previous tests by 150:

0.88*150 = 132

0.94*150 = 141

0.9*150 = 135

The total number of points possible is given by adding up the possible points for the three previous tests and the 250 for the last test:

150+150+150+250 = 700

93% of the 700 points would be 0.93(700) = 651 points.

Now we have 132+141+135+x (last test) = 651

408 + x = 651

Subtract 408 from both sides:

408+x-408 = 651-408

x = 243

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
