grade David has to earn on his 5th test to maintain a test
average of 90?
Answer:
81
Step-by-step explanation:
Required average= 90
let the required grade be x

90= 89+96+99+85+x divide by 5
450= 369+x
x = 450-369
x=81
The total surface area of a cube is 294cm^2.
Work out the volume of the cube.
Answer:
343 cm ^3
Step-by-step explanation:
A cube has 6 squares of equal sizes. 294/6 = 49
The area of one square is 49
Since the area is the length squared, the square root of 49 is 7.
Volume of a cube is area times height. 49 x 7 = 343 cm^3

Write a fraction on the blank to make the comparison true .Use the fractions form the box .Explain how you choose your number 3/5>3-4
Answer:
Explained
Step-by-step explanation:
So I'm not sure if you mean by 3/4 or 3-4. But I'm going to assume that its 3-4 because 3/4 is greater than 3/5
3/5 is equal to 0.6 -> you can also find 0.6 by multiplying 3/5 * 2 on both sides which will be 6/10 which is 0.6
and 3-4 is - 1 (which is negative)
since 3/5 is positive and 3-4 is negative. You would know that this is true.

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17 units
Step-by-step explanation:
Moving from (-8, 0) to (7, 8), we see x changing by 15 units from -8 to 7 and y changing by 8 units from 0 to 8.
Regard 15 units as the horizontal leg of a right triangle and 8 units as the vertical leg. We use the Pythagorean Theorem to determine the length of the hypotenuse of this right triangle and interpret the result as the distance between the points:
d = √(15² + 8²) = √289 = 17
The distance between the given points is 17 units.

Write the slope intercept equation for this table
Answer:
y = 2x -4
Step-by-step explanation:
y2 - y1 / x2 - x1
-4 - (-6)/ 0 - (-1)
= 2
y = mx + b
y = -2x + b
-4 = -2(0) + b
-4 = 0 + b
-4 = b
So the equation is y = 2x -4

How much larger is the circumference of circle A than the circumference of circle B?
Give your answer to one decimal place.
diameter of circle A is 13 and B is 8
Answer:
Circumference of Circle A is about 16 units larger than the Circumference of Circle B
Step-by-step explanation:
Formula for Circumference of a circle = πd
Where, d = diameter of circle
Thus:
Circle A diameter = 13
Circle B diameter = 8
Therefore:
Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)
Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)
✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16
Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B

Team A and team B play in a competition Team A has 12 more points than team B Team A has twice as many points as team B How many points does each team have
Answer:
A = 24 points
B = 12 Points
Step-by-step explanation:
Team A and team B play in a competition
Team A has 12 more points than team B
A = B + 12
Team A has twice as many points as team B
A = 2B
We substitute
2B = B + 12
2B - B = 12
B = 12 points
Solving for A
A = 2B
A = 2 × 12
A = 24 points
Here are the percents of the popular vote won by each successful candidate in 15 presidential elections. 49.6, 55.1, 57.4, 49.7, 61.1, 43.4, 60.7, 50.1, 50.7, 58.8, 53.9, 43.2, 49.2, 47.9, 51.2 what is the maximum
Answer:
Maximum = 61.1
Step-by-step explanation:
Given - Here are the percents of the popular vote won by each successful candidate in 15 presidential elections. 49.6, 55.1, 57.4, 49.7, 61.1, 43.4, 60.7, 50.1, 50.7, 58.8, 53.9, 43.2, 49.2, 47.9, 51.2
To find - What is the maximum ?
Proof -
We have to find which candidate got highest votes in the election .
For this, we first arrange all 15 in ascending order i.e. lowest to highest.
Now,
The arrangement is like this -
43.2,
43.4,
47.9,
49.2,
49.6,
49.7
50.1,
50.7,
51.2,
53.9,
55.1,
57.4,
58.8,
60.7,
61.1
From this , we get
Lowest votes = 43.2
Highest votes = 61.1
⇒Maximum = 61.1

A container of chocalates has a ratio of dark to milk chocolates of 3 to 5. If you have 18 dark chocolates, then how many milk chocolates do you have?
Answer:
30 milk chocolates
Step-by-step explanation:
We can set up the equation like this: 3*x=18
So we can solve that by 18/3 = 6
Now the mile chocolates are 5x, so if you multiply 5 by 6, you get 30
