Answer:
The number b is bigger than the number a by 1/4 of a.
Step-by-step explanation:
If the number a is smaller than the number b by 1/5 of b, then
a + 1/5b = b.
Thus,
a= b - 1/5b= 4/5,
b= 5/4 a.
Consider the Expression b=5/4a:
b=5/4a= 4/4a+ 1/4a= a +1/4a
This gives that the number b is bigger than the number a by 1/4 of a.

What value of y makes the equation 6(x-4)+2 = 36/4 true?
Answer:
31/6
Step-by-step explanation:
36/4=9
6x-22= 9
6x= 9+22
substitute 6x=31= 31/6
Answer:
x = 31/6
Step-by-step explanation:
first lets isolate the equation which equals, 6x-24+2 = 9
I got 9 from 36/4, divide top and bottom by 4 = 9
Next add the numbers, 6x -24+24= 9 turns into 6x-22= 9
Now move the -22 to the side the 9 is, 6x= 9+22
and now we can solve and substitute, 6x=31, which gives us 31/6

Is 1/4 (8y -12) equivalent to 2y - 12? No. 1/4 (8y-12) equals out to 2y-3 not 2y-12. To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1
what divided by 4 is 8?
Answer:
32
Step-by-step explanation:
If the question is x (standing for an unknown number) divided by 4 equals 8, then 8 times 4 should equal that unknown number.
x / 4 = 8
x / 4 (*4) = 8 (*4)
x = 32
We now can replace x with our number and see if this answer is valid.
x / 4 = 8
32 / 4 = 8
And yes, it is true. Therefore, 32 divided by 4 is 8.
I hope this helps! Have a lovely day!! :)

The horizontal flat box has dimensions of
h = 2
w = 7
l = 21
The vertical box has dimensions of
h = 10
w = 7
L = 12
Formula
V = L * w * h
Solution
Horizontal Flat Box = L*w * h
Horizontal Flat Box = 21 * 7 * 2
Horizontal Flat Box = 294
Vertical Box
Vertical Box = L * w * h
Vertical Box = 12*7 * 10
Vertical Box = 840

A.0
B.1/2
C.1/3
D.1/4
Answer:

Step-by-step explanation:
Because since there are 4 people with an equal chance to win then you just put the number of people that you're trying to figure out over the total number.
Answer:
d
Step-by-step explanation:
we know there is 4 students so that means there's a 1/4 chance of him winning

Martin tracked the amount of water he drank for an entire week. The bar graph shown here displays the information about his water consumption. What is the mode of the daily data A)8 B) 10 C)12 D)14
Answer:
c)12
Step-by-step explanation:
since on the bar graph 12 occurs the most that is the mode so hope this helps!
The mode of the daily data is 12 cups.
How to identify skewed graph?A skewed distribution is a distribution having bias on one of the two sides (either left or right).
It is like leaning mountain on one side (left or right).
A left skewed graph have elongated tail on the left side of the main mountain like figure. The mountain like figure is after that elongated tail. It is also called negatively skewed graph. This graph usually has mean < median < mode.
A right skewed graph has elongated tail on the right side of the main mountain like figure. The mountain like figure is before that elongated tail. It is also called positively skewed graph. This graph usually has:
Mode < median < mean.
We are given that;
The bar graph show 8cups on monday, 12 cups on tuesday, 10 cups on wednesday, 16 cups on thrusday, 12 cups on friday, 14 cups on saturday and 18 cups on sunday.
Now,
The mode of a set of data is the value that occurs most frequently.
Looking at the bar graph, we can see that the values 8, 10, 12, 14, 16, and 18 all occur once, but only one value occurs more than once, which is 12 cups on Tuesday and Friday.
Therefore, by skewed distribution the answer will be 12.

Jackson has a cube. Each edge of the cube is 5 centimeters long, as shown below.
Part A
Jackson paints every face of the cube. What is the total surface area, in square centimeters, of the cube
Jackson paints? Be sure to show your work and explain your reasoning.
Part B
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Part C
Jackson has a second cube identical to the first. He cuts off the triangular prism as shown below and throws
it away.
What is the volume, in cubic centimeters, of the remaining solid? Show or explain all your work.
Answer:
Part A- Surface area = 150cm squared
Step-by-step explanation:
First you find the area of one side of the cube-
side length (5) x side length (5) = area (25)
25 is the area of one side of the cube.
Then you multiple the area of one side (25) by the amount of sides that there are (6)-
25 x 6 = 150

If you spun the spinner 1 time, what is the probability of landing on either a white piece or a gray?
the circle in the picture has 3 gray and 5 white
there are 9 pieces in total
Answer:
[tex]\frac{8}{9}[/tex]
Step-by-step explanation:
So, there are 8 pieces with color and 1 piece without the wanted color.
The equation for finding the probability is: [tex]\frac{sum of terms }{number of terms }[/tex]
Therefore: 3 + 5 = 8 and 9 pieces in total
so the correct answer should be 8/9
