christian has six grades from tests and IXL. they are all weighted equally. if christian grades are 100,96,96,88,70 and 100, what is the current average grade (round to the nearest whole number)

Answer:

a. 70%

b. 6 more times

c. subtract from 100% with percentages, subtract from 1 with decimals.

Step-by-step explanation:

a. To find the percentage of red and yellow, skip back the decimal point two times: 0.26 > 26%     0.04 > 4%

Add all of the percentages together to get 70%

b. To find how many times more students said red than yellow, divide yellow from red. It shows you how many times yellow can go into red, giving you the correct answer.

0.26 ÷ 0.04

26 ÷ 4

6

c. 14% + 26% + 40% + 4% = 84%

100% - 84%

16%

(do the same thing with decimals and pick your favorite method)

Answer:

1.2 m off the ground

Answer:

x = 12

y = 16

Step-by-step explanation:

Use the Pythagoras Theorem on the left triangle.

[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(x)^2=(7.2)^2+(9.6)^2\\x^2=51.84+92.16\\x^2=144\\x=\sqrt{144}\\x=12\\[/tex]

Now use the Pythagoras Theorem on the right triangle.

[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(y)^2=(12.8)^2+(9.6)^2\\y^2=163.84+92.16\\y^2=256\\y=\sqrt{256}\\y=16\\[/tex]

Answer:

69?

Step-by-step explanation:

Answer:

The equation of the line is:

[tex]y = 4x + 3[/tex]

Step-by-step explanation:

We know that the slope-intercept of line equation is

[tex]y = mx+b[/tex]

Where m is the slope and b is the y-intercept

Given the two points on a line

Finding the slope between (0, 3) and (-2, -5)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-5\right)[/tex]

[tex]m=\frac{-5-3}{-2-0}[/tex]

[tex]m=4[/tex]

We know that the y-intercept can be computed by setting x=0 and determining the corresponding y-value.

From the graph, it is clear:

at x = 0, y = 3

Thus, y-intercept = b = 3

Substituting m = 4 and b = 3 in the slope-intercept form of line equation

[tex]y = mx+b[/tex]

[tex]y = 4x + 3[/tex]

Therefore, the equation of the line is:

[tex]y = 4x + 3[/tex]

Answer:

4/8 more pounds

Step-by-step explanation:

7/8-3/8=4/8

Answer:

Jon ate 5/8 more pounds of blueberries than Meg.

Step-by-step explanation:

This is because the question is asking for the difference between how many blueberries Meg ate, and how many Jon ate. Therefore, we have to use subtraction.

7/8 - 3/8 = 5/8, therefore Jon ate 5/8 lb more than Meg.

Answer:

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Step-by-step explanation:

Given

The attachment

Required

Express the area as a sum of stores and parking lots

First, calculate the area of the stores

[tex]Store\ A = 25\ by\ 10[/tex]

[tex]Store\ B = 25\ by\ w[/tex]

[tex]Stores\ A\ and\ B = 25\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_1 = 25 * (10 + w)[/tex]

Next, calculate the area of the parking lots

From the attachment, we have the following

[tex]Parking\ lot\ A = 13.5\ by\ 10[/tex]

[tex]Parking\ lot\ B = 13.5\ by\ w[/tex]

[tex]Parking\ lots\ A\ and\ B = 13.5\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_2 = 13.5 * (10 + w)[/tex]

The area of the shopping centre is then calculated as:

[tex]Area = A_1 + A_2[/tex]

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Answer:

Reduced/depressed

courageously/daringly

Boost/inflate

Explanation:

The following statement displays the recommendation of National Football League's(NFL) rule to wear new and lighter helmets by the players to diminish the chances of head injury during collisions between players. However, it has led the players to play more brazenly and fearlessly that eventually may cause the expansion of the number of collisions suffered by NFL players due to the valiant behavior of the players. This equates the ratio and leading to no improvement in the reduction of injuries among them even after this rule.

Equation: x × -2 = y

Solution: y = 12

Step-by-step explanation:

if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.

Answer: 12n + 60

Step-by-step explanation:

So first you have to distribute the 5 in the parentheses.

(5)(n + 12) = 5n + 60

5n + 60 + 7n

Then add like terms.

12n + 60

Answer:

Step-by-step explanation

8(-1)^4-3(-1)-7= ?

multiply 8 * -1= -8

so -8^4= 4096 that part is done.

now do -3 * -1 and get 3 because two neg. = posit.

so now the question should say

4096+3-7=?

4096+3= 4099-7= 4092

x=4092 i think unless that isnt what you are doing im srry if this is incorrect i tryed and i hope this is correct...again im srry if this is incorrect
