Answer:
2/7, 7/13, 5/9, 10/11
Step-by-step explanation:
I used benchmark fractions to determine the order of the fractions above. 2/7 is close to 0, so it is first. 7/13 is close to 1/2, but is less than 5/9, so it is second. 5/9 is also close to 1/2, but it is greater than 7/13, so it is third. 10/11 is close to 1, so it is last.

The mean of four numbers is 25. Three of the four numbers are 20, 26, and 26. What is the fourth number?
Answers
Answer:
28 hope this helped
Step-by-step explanation:
20+26+26=72
72+28=100
100/4=25
let the number be X
20 + 26 + 26 + X /4 = 25
72 + X /4 = 25
cross multiply
72 + X = 25*4
72 + X = 100
X = 100.- 72 = 28
X = 28
proof
20 + 26 + 26 +28 / 5 = 25

a) A graph is drawn below.
Explain how you know that y is not directly proportional to x.
Answers
Answer:
Because the line doesn’t start at 0 and that shows that y is not proportional to x.
Step-by-step explanation:
That is all you have to write
A graph can show direct, inverse and joint proportions.
y is not directly proportional to x because the graph does not pass through the origin
From the graph, we can see that:
When x = 0, y > 0
i.e. y is greater than 0, when x equals 0
This means that, the equation of the graph is:
[tex]\mathbf{y = mx + b}[/tex], where b > 0
A proportional equation is represented as:
[tex]\mathbf{y = mx}[/tex]
Hence, y is not directly proportional to x because the graph does not start from the origin

Find the surface area of an open box with length of 12 inches, width of 7 inches, and height of 4.5 inches
Also, Good Moring
Worth 20 points
Answers
Answer:
Step-by-step explanation:
l = 12 inches
w = 7 inches
h = 4.5 inches
Surface area = lw + 2wh + 2hl
= 12*7 + 2*7*4.5 + 2*4.5*12
= 84 + 63 + 108
= 255 square inches
If it is a closed box, surface area = 2*(lw +wh + hl)
As it is open, surface area = lw + 2wh + 2hl
Down part of the box : length *width
Upper part of the box = length*width
So, for closed box, 2lw
For open box , lw

If Kevin wants a 90 average in math after 5 tests and his first 4 tests are 76, 92, 89 and 97 what does he need on the fifth test for a 90 average?
Answers
Solving for the average is simple:
Add up all of the exam scores and divide that number by the number of exams you took.
(87 + 88 + 92) / 3 = your average if you didn't count that fourth exam.
Since you know you have that fourth exam, just substitute it into the total value as an unknown, X:
(87 + 88 + 92 + X) / 4 = 90
Now you need to solve for X, the unknown:
87
+
88
+
92
+
X
4
(4) = 90 (4)
Multiplying for four on each side cancels out the fraction.
So now you have:
87 + 88 + 92 + X = 360
This can be simplified as:
267 + X = 360
Negating the 267 on each side will isolate the X value, and give you your final answer:
X = 93
Now that you have an answer, ask yourself, "does it make sense?"
I say that it does, because there were two tests that were below average, and one that was just slightly above average. So, it makes sense that you'd want to have a higher-ish test score on the fourth exam.
current count = 4
current sum = 76+92+89+97=354
we need average = 90 = sum/5
so, we need sum = 90*5=450
To get sum 450, he needs to score 450-354=96 on his best test.
Now, (76+92+89+97+96)/5=90

What is the approximate area of the congruent orange right triangles?
A. 17 in2
B. 31 in2
C. 33 in2
D. 51 in2
Answers
Answer: The answer is A 17in2
Step-by-step explanation:
In the question it states that the triangles are congruent (both the same).
first I found the area of the top orange triangle.
the formula to find the area of a triangle is [tex]\frac{1}{2} bh[/tex] (base times Height).
so I did [tex]\frac{1}{2} 3.23* 5.12[/tex] which gave me 8.27.
Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.
the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)

A small pouch contains 8 black marbles,5 white marbles, and 12 red marbles. Find the probability of picking a red then a black marble if you do not replace the first marble.
Answers
Answer:
4/25
Step-by-step explanation:
Total amount of marbles: 8 + 5 + 12 = 25
With 25 marbles, the probability of picking a red is: 12/25
After 1 red marble is removed, the probability of picking a black is: 8/24 = 1/3
Then, the probability of picking a red then a black marble if you do not replace the first marble is: 12/25 * 1/3 = 4/25

Step-by-step explanation:
Probability of picking a red sock the first time: 7/12
Probability of picking a red sock the second time: 6/11 (Since you already took out one sock, thus decreasing both the number of red and total socks in the drawer.)
7/12 * 6/11 = 42/132
42/132 = 7/22
Jocelyn has 6 birds. Their mean age is 10. The mode of their age is 8 . What might there ages be ??.
Subject - Math ( Mean, Median, and Mode ) PLZ write the answer correctly !! The best answer will be marked as Braintlies !!
Answers
Answer:
total ages = 60
Generally, if the mode is 8 would mean there are more than one age of 8
suppose there are two with age 8,
leaving 44 for the other 4
(11 for the average of the remaining 4)
could have 9 and 13, and 8 and 14
so we could have:
8,8,8,9,13,14
or we could have:
8,8,9,10,12,13
check:of the 1st answer
mean = (8+8+8+9+13+14)/6 = 10
the mode is 8
Step-by-step explanation:
Because there is 6 birds having all the ages add up to 60 then dividing it by the 6 will give you the mean 10.
When making those numbers you need to make sure that you have multiple 8’s because that is the mode which means the most occurring number.
The answer could be :
8+8+8+13+12+11
8+8+8+8+18+10

At the amusement park each students is given $16 dollars for food. This covers the cost of 2 meals plus $4 for snacks. how much money does the school expect each student to spend per meal. Which equation can be used to represent this situation? plz help now if u can
Answers
Answer:
16 = 2x + 4
Step-by-step explanation:
The total amount of money they are given is $16. That is split up into 2 equal groups with 4 left over. So you'd have to subtract 4 from both sides. Then divide both sides by 2. This will give you the answer to how much money they expect the students to spend on food.

B 180 feet
C 90 feet
D 16,200 feet
Answers
Answer:
A straight line from home plate to second base would have distance:
D = sqrt(2 x 90^2) = 127.3 feet
=> Option A is correct
Hope this helps!
:)
The distance from the home plate to second base in a straight line is required.
The required distance is option A 127.3 feet.
SquareA baseball field is in the shape of a square this means that all corners have the angle [tex]90^{\circ}[/tex]
So, two sides of the square can act as legs of a right triangle and the diagonal can act as the hypotenuse.
A straight line between the home plate and second base would be the diagonal of the square.
The length of each side of the square is 90 feet.
Applying the Pythagoras theorem
[tex]d=\sqrt{90^2+90^2}\\\Rightarrow d=90\sqrt{2}\\\Rightarrow d=127.279\approx 127.3\ \text{feet}[/tex]

what is the equation of the line passing through ( -5, -3 ) and perpendicular
to the line representing the equation y = - 5/7x + 2?
Answers
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

Step-by-step explanation:
Here are a system of how two equations can be classified ;
• If the gradients are the same but the y-intercepts are different, the system has no solution.
• If the gradients are different, the system has one solution.
• If the gradients are the same and the y-intercepts are the same, the system has infinitely many solutions.
Here is the proof.
3y - 9x = -6
5y - 15x = -10
In
3y - 9x = -6
When x =1
y= 1
When x=3
y= 7
Gradient of 3y - 9x = -6
=∆y/∆x
= (7-1)/ ( 3-1)
=(6)÷ 2
= 3
5y - 15x = -10
When x= 1
y = 1
When x=3
Y=7
Gradient of 5y - 15x = -10
=∆y/∆x
= (7-1)/ ( 3-1)
=(6)÷ 2
= 3
Since the gradients are the same the system has infinitely many solutions.
