Katherine earned 84, 92, 84, 75, and 70 on her first 5 tests.
What is the minimum grade Katherine needs to earn on the next test to have a mean of 84?

Answer & Step-by-step explanation:

When you are doing the reflection, y = -x, then the coordinates will go as follow...

(x, y) → (-y, -x)

So, (3, 5) will become (-5, -3).

So, the coordinate of F' would be (-5, -3)

Answer:

the equation is not shown...

Step-by-step explanation:

but to solve for y you should use the first equation that is use the coefficient of x in the first equation to multiply all the terms in the second equation.

And use the coeffient of x in the second equation to multiply the the terms in the first equation.

It would have been better if the equation was shown for better explanation.

Answer:

A number cube

Step-by-step explanation:

A coin a 5-sector spinner a number cube a bag of 11 marbles

A number cube is the best to simulate this scenario and predict whether a randomly chosen resident has a library card.

As Coin has only 2 outcomes "Head" and "Tail".

A 5-sector sector spinner has only 5 outcomes we need six outcomes.

A bag of 11 marbles has no differentiated with respect to colors etc.

Hence, A number cube is correct to chosen five out of six residents of Mayville have library cards.

Answer:

A= 1/2bh

Step-by-step explanation:

The answer is the Area= 1/2 * base * height

Answer:

Step-by-step explanation:

because A regular octagon is a closed figure with sides of the same length and internal angles of the same size. so if it is rotated 360 degrees it should coincide with its preimage after every 45 degrees.

so 360/45= 8 times

Answer:

8 times

Step-by-step explanation:

An octagon has eight sides of equal length and eight angles of same measure. So, If it is rotated 360 degrees about its center. It would coincide with all of its 8 sides. So, it will coincide with it's pre-image 8 times.

Answer:

Answer:

√65 (units)

Step-by-step explanation:

A(3, -2) and B(7, 5)

AB=√ [(xB-xA)²+(yB-yA)²]

AB=√ [(7-3)²+(5+2)²]=√(16+49)

AB=√65 (units)

Answer:

1. When adding you just add the numbers from the same space so

Answer:

The side length is 8x+2 ft

Step-by-step explanation:

The perimeter of a square is found by

P =4s  where s is the side length

32x +8 = 4s

Divide each side by 4

32x/4 +8/4 = 4s/4

8x+2 = s

The side length is 8x+2 ft

Hi there!

Answer:

1/6

Explanation:

The first probability of getting blue is 4 out of the total marbles so 4/9.

The second time there are only 3 blue marbles out of 8 now so 3/8.

So the answer is 4/9X3/8

which equals 12/72 or 1/6

Answer:

side of square is 2-x

Step-by-step explanation:

Area of the square is side * side  or side ², so the expression for the side has to be square root of area

A = 4 -4x + x²

It should be recognized that 4 -4x + x²is a special product ( 2-x)² because this is a perfect square trinomial

side of square is 2-x

Answer:

Step-by-step explanation:

The area formula for a parallelogram is the same as the area formula for a rectangle or square. A = bh.

Our base is 5 1/4 and the height, which drops perpendicular to the base, is 4 1/5.  So the formula for the area is

[tex]A=(4\frac{1}{5})(5\frac{1}{4})[/tex]

[tex]\frac{600}{1440} \\0.416667[/tex]

Answer:

0.417 day

Step-by-step explanation:

First divide 600 by 60 the answer is 10 hours and then divide by 24 the answer would be 0.41666667 days

Answer:

56

Step-by-step explanation:

so a straight line has an angle that is 180 degrees

the angle on both sides of X are 64 and 60

so add those up u get 124

get the whole angle of 180 and subtract 124 and u get 56

Answer:

Step-by-step explanation:

Use Pythagorean theorem

let the missing side be x

5² +x² = 13²

25 + x² = 169

x² = 169 - 25

x² = 144

x =√144

x = 12 yards

Answer: The equation would NOT help us solve for the length and width of the classroom is "[tex]x + 2y = 90[/tex]".

Step-by-step explanation:

Let y be the width of the rectangular classroom floor and x be the length of the rectangular classroom floor .

Given ,

The perimeter of a rectangular classroom floor is 90 feet.

The length of the floor is twice the  width.

i.e. Length =2 (width)

i.e. x= 2y ..(i)

Also, perimeter = 2(length+width)

[tex]i.e. 2(x+y)=90\\\\\Rightarrow\ 2x+2y=90[/tex]

When we put value of x from (i), we get

[tex]2(2y) + 2y = 90[/tex]

Hence, the equation would NOT help us solve for the length and width of the classroom is "[tex]x + 2y = 90[/tex]".

Therefore, the probability of getting a total of three is 2

Probability of getting total of three when two fair dice rolled is equals to [tex]\frac{1}{18}[/tex] .

" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability [tex]= \frac{Number of favourable outcomes}{Total number of outcomes}[/tex]

According to the question,

Dan rolls two fair dice,

Possible outcomes are [tex]= \{ (1,1), (1,2), (1,3) , (1,4). .........., ( 6,5), (6,6)\}[/tex]

Total number of outcomes [tex]= 36[/tex]

Condition given,

Favourable outcomes for total of [tex]3[/tex] [tex]= \{(1,2) , (2,1)\}[/tex]

Substitute the value in the formula of probability we get,

Probability of getting [tex]3[/tex]

[tex]= \frac{2}{36}\\\\= \frac{1}{18}[/tex]

Hence, probability of getting total of three when two fair dice rolled is equals to [tex]\frac{1}{18}[/tex] .

then convert 8000 pounds to tons and you get 4 tons

Answer:

No solutions

Step-by-step explanation:

x + 2y and 2x + 4y are linear combinations of each other since 2 ( x + 2y ) = 2x + 4y.

However, since 2 ( x + 2y = 2 ) results in 2x + 4y = 4 and the second equation reads as 2x + 4y = -8, there is no solution to this system of equations since 4 does not equal -8.
