Kara has five exam scores of 93, 67, 82, 71, and 94 in her biology class. What score does she need on the final exam to have a mean grade of 80?
Round your answer to two decimal places, if necessary. (All exams have a maximum of 100 points.)

Answers

Answer:

She needs at least 73%

Step-by-step explanation:

1. add all of the numbers up and d the quantity to find

93+67+82+71+94/5

=407/5

=81.

2. try diffrent numbers

407+73/6

=480/6

=80

She needs at least 73%

Answer:

A score of 73

Step-by-step explanation:

Five exam scores + the final exam = mean (average) of 80.

First find the total points that you need to make an 80 average 80 × 6 = 480 points.

The five exam scores + x score = 480 points.

93 + 67 + 82 + 71 + 94 + x = 480

407 + x = 480

x = 480 - 407

x = 73

Find the volume of the sphere. **30 points**
Either enter an exact answer in terms of pi or with 3.14
Radius=8

Answers

Answer:

The volume of the sphere is 2,143.57

Step-by-step explanation:

The formula for finding the volume of the sphere is

V = [tex]\frac{4}{3}[/tex]π[tex]r^{3}[/tex]

"r" represents the radius of the sphere. So put the value of it in the formula.

V = ([tex]\frac{4}{3}[/tex])(3.14)([tex]8^{3}[/tex])

V =  ([tex]\frac{4}{3}[/tex])(3.14)(512)

Multiply all of them and you will get:

2143.57333333 or 2,143.57 which is the volume of the sphere

C. y= x + 12
D. y = 12

Answers

Answer:

The correct answer is option D

Step-by-step explanation:option A : y = x/12 ⇒ x = 12y (wrong option)

option B : y = 12/x ⇒ y * x = 12 (wrong option) and c will be equal 12

option C : y = x + 12 ⇒ not similar to the general form (wrong option)

option D : y = 12/x (corect option)( I meant to switch it around)

The general form of inverse variation between the variables x and y is as following:

where c is constant

assume that y varies directly as x. if y=7 when x=4, find y when x=12

Answers

Answer:

y = 21

Step-by-step explanation:

since y = 7 as x = 4, therefore, when x = 12, y = 21

Think about it. if you divide 7 by 4, you get 1.75 and if you divide 21 by 12, you get 1.75. That means that from 4 to 12, I multiplied by 3, so therefore, y = 21.

GIVING 100 POINTS AND BRAINLIEST IF CORRECT! You recently upgraded your experience by buying an Controller for $74.99 and an Game Pass Subscription for $14.99 per month.

Answers

Answer:

Part A: It's linear because it increases at a constant rate of 14.99 dollars per month

Part B: C = 14.99M + 74.99 (y = 14.99x + 74.99)

Step-by-step explanation:

Part A: Every month, you have to pay the same amount.

1 month = 14.99

2 months = 14.99 + 14.99

3 months = 14.99 + 14.99 + 14.99

So, it's linear.

Part B: We have to use the formula y = mx + b, or slope-intercept form, to represent the total cost per month.

m = slope,   b = y-intercept (initial value)

Let's have the total cost  be represented as C

Let's also have the subscription per month be represented as M

So, C would = 74.99, because we only need to pay for a controller once

But we also our subsription per month, M, as 14.99.

So our final answer would be C = 14.99M + 74.99, or y = 14.99M + 74.99 if you can't make your own variables

At a certain time of day, a tree that is x meters tall casts a shadow that is x - 23 meters long. If the distance from the top of the tree to the end of
the shadow is x + 2 meters, what is the height, x, of the tree?

Answers

Answer:

The height, x of the tree is 35 meters

Step-by-step explanation:

use Pythagorean  theory to answer

(x+2)^2= x^2+(x-23)^2

[tex]x^{2}[/tex]+4x+4=[tex]x^{2}[/tex]+[tex]x^{2}[/tex]-46x+529

re-arrange the equation and collect like terms

[tex]x^{2}[/tex]-50x+525=0

(x-35)(x-15)=0

x=15 or x=35

x cannot be 15 because 15-23 is a negative answer

therefore the height of tree is 35 m

You’re trying to find a certain high temperature. You know that the low is 51°, which is 17° lower than the high temperature(h). With this information, you can find that h=68 (51+17). To get from 68° to 51°, you would subtract 17°. Making the equation 51=h-17.
