Answer:
12 Men, 27 men and women together.
Step-by-step explanation:
Well we know there are 15 women. The ratio of men to women is 4:5 so that means every 4 men, there are 5 women. If we divide 15 by 5, we get 3. Now we multiply 3 to the number of men which is 4 because what happens to one part of the ratio then happens to the next. Added together, 12 plus 15 equals 27 so that is the total. Hope this helps!

A bag contains exactly three red marbles, five yellow marbles and two blue marbles. If three marbles are drawn from the bag without replacement, what is the probability that all three will be the same color? Express your answer as a common fraction
Answer:
11/120Step-by-step explanation:
Red = 3Yellow = 5Blue = 2Possible options would be red or yellow as only two blue marbles.
Probability of 3 red:
3/10*2/9*1/8 = 1/120Probability of 3 yellow:
5/10*4/9*3/8 = 1/12Probability of same three is:
1/120 + 1/12 = 11/120Could someone help me with this question?

A bowl holds 4 cups of rice if I use a measuring cup that holds 1/8 of a cup how many times will I need to fill the measuring cup in order to fill the entire bowl
Answer:
32 times
Step-by-step explanation:
It's SUPER easy, all you have to do is take that 1/8 and make it into a regular 8. Now all you do is multiply 4 by 8.
I know there's probably some way the teachers taught that's so much harder then it already is, but if you try to look at it from an easier perspective, you'll be a pro!
Try some more so you'll slowly start getting better at them! Anyway I hope this helped!!
Please help!! I just need help with question 40!!
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)

If y varies directly as x and x=2 when y=−4, find y when x=−6.
Equation: ____________
Solution: y = ___________
Answer:
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.

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
Answer:

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]
Meg ate 3/8 pound of blueberries. Jon ate 7/8 pound of blueberries. How many more pounds did Jon eat than
Meg?
Please help me
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.
I'm confused, how would I do this?
Write a function in the form y = mx + b for the line that passes
through the points (2, 4) and (6, 16).
Write an equation of the line below
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
(0, 3)(-2, -5)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]

Find the values of the variables in each right triangle.
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]
