Robin draws a tile from a bag that contains 4 white tiles, 5 green tiles and 9 yellow tiles. She then draws a second tile without replacing the first. What is the probability that both tiles Robin draws are white?
WILL ONLY GIVE BRAINLIEST IF EXPLAINED PROPERLY
Answer:
2/51
Step-by-step explanation:
there are 4 white tiles and 18 total tiles in the bag, so your ratio is 4 out of 18 and 2/9 when simplified. When Robin draws out the first one, if it is white, then because he keep that one out, there are only 3 white tiles left and 17 total tiles left, so 3/17 is his chance of drawing a white the second time. you multiply 2/9 and 3/17 together because there is a chance for him to draw the white tile the first time and a chance to draw a white again the second time, so it is reasonable for the chance to be really small. 2/9 x 3/17=2/51.

Answer:
D. $60Step-by-step explanation:
If the amount is equal and each is 20% = $12, then total is:
100% = 20%*5 = $12*5 = $60Correct choice is D
Answer:
60.00
Step-by-step explanation:
20% of 60 = 12 which equals the amount of money Peter has.
So, at $60, he has 20% and $12.00

5(x + 3) - 2 = 2 + 5x + 9
Answer:
There is no solution
Step-by-step explanation:
[tex]5(x + 3) - 2 = 2 + 5x + 9[/tex]
[tex]5x+15-2-2-5x-9=0\\15-13=0\\2=0[/tex]
There is no solution
because 2=0 is not possible.
→5(x + 3) - 2 = 2 + 5x + 9
→5x+15-2 = 11+5x
→5x-5x = 11-13
→x = -2

Answer:
- 20x² + 26x + 8
Step-by-step explanation:
Given
4(2x³ - 5x² + 8x + 2) - 6x - 8x³ ← distribute parenthesis by 4
= 8x³ - 20x² + 32x + 8 - 6x - 8x³ ← collect like terms
= - 20x² + 26x + 8

express 13/50 as a percentage
Answer:
26%
Step-by-step explanation:
How can we turn a fraction into a percentage well if 1.00 is 100% and 0.90 is 90% we can see that we can easily convert between decimal and percents. The fraction 13/50 is the same thing as 13 divided by 50 which is 0.26. So our answer is 26%
Answer: 26%
Step-by-step explanation:
13/50 = 26/100 =26%

I think it is six thats what i got
Answer:
6 units²
Step-by-step explanation:
Since the triangle is reflected they should have the same length sides (triangles are congruent) so you would use the length they give you for side AC in the first triangle and the length of the side AB in the second triangle to determine the area
Area= ½ base × perpendicular height
=½4 ×3
=6 units²
Hans, a clothing designer, has $38 to buy zippers. Each zipper cost $2.50. The equation y=2.50x represents the relationship between the number of zippers and the cost. How many zippers can Hans buy?
X represents?—————
Y represents?—————
K= —————
Solution: (——-,——-)
The solution does or does not make sense in the situation because—————
Hans can buy ——— zippers
Answer:
X = Amount of zippers she can buy
Y = Total cost
K = each zipper cost, $2.50
Solution: Hans can buy 15 zippers
Step-by-step explanation:
38 = 2.50x
x = 15.2 = 15 zippers

a. If the average North Korean farmer produces 1,500 pounds of food per year, what is the opportunity cost, In pounds of food, of North
Korea's army?
______ pounds of food per year
b. If a person needs at least 500 pounds of food per year to survive, how many people could have been fed with the forgone food output?
_____ people
Answer:
1,920,000,000 pounds of food per year and 3,840,000 people.
Step-by-step explanation:
1,280,000 active military members could have been farmers that produced 1,500 pounds of food per year. (1,280,000 farmers x 1,500 pounds of food = 1,920,000,000).
1,920,000,000 divided by 500 pounds of food per person is 3,840,000.
Suppose u and v are orthogonal vectors with ||u|| =5 ||u||= 1/2 ||v||, find ||u+v||.
help pleas I will give you 15 points
Answer: 5*sqrt(5)
This is the same as sqrt(125).
It approximates to roughly 11.1803
=========================================================
Explanation:
Vector u is 5 units long as indicated by the notation ||u|| = 5. Some math books would say |u| = 5, and it's the same thing. The double bars are probably more fitting because it helps emphasize we're looking for the length of a vector and we're not using absolute value bars.
The second equation ||u|| = (1/2)*||v|| can be rewritten into ||v|| = 2*||u|| telling us that vector v is twice as long compared to vector u. Since vector u is 5 units long, that must mean vector v is 10 units long.
vector u = 5 units longvector v = 10 units longThe two vectors are orthogonal, i.e. they are perpendicular. The vector u+v represents the diagonal of the rectangle as shown below in the attached image. Vector u is horizontal, v is vertical, and u+v is the diagonal. Technically we don't know where vector u is pointed along a compass (it may or may not be pointing directly east), but I find it's easier to have it set up like this. The answer will be the same regardless of where vector u is pointed. Rotations don't affect vector lengths.
We can see that vector u+v effectively breaks down component-wise into the horizontal component u and vertical component v (think of them as x and y components respectively).
Furthermore, note how there are two right triangles that form when we draw in the diagonal of the rectangle.
To find the length of vector u+v, we apply the pythagorean theorem.
a^2+b^2 = c^2
( ||u|| )^2 + ( ||v|| )^2 = ( ||u+v|| )^2
( 5 )^2 + ( 10 )^2 = x^2
25 + 100 = x^2
125 = x^2
x^2 = 125
x = sqrt(125)
x = sqrt(25*5)
x = sqrt(25)*sqrt(5)
x = 5*sqrt(5) is the length of vector u+v
In other words, ||u+v|| = 5*sqrt(5)
Keep in mind that this trick using the pythagorean theorem only works when vectors u and v are orthogonal. The process to find ||u+v|| for non-orthogonal vectors u,v is a bit more complicated.

-99>5-8(m+6)
need help
Answer:
m > 7
Step-by-step explanation:
[tex] - 99 > 5 - 8(m + 6)[/tex]
[tex] - 8(m + 6) = - 8m - 8 \times 6[/tex]
[tex] = - 8m - 48[/tex]
[tex] - 99 > 5 - 8m - 48[/tex]
[tex]5 - 48 = - (48 - 5) = - 43[/tex]
[tex] - 99 > - 43 - 8m[/tex]
[tex] - 99 + 8m > - 43[/tex]
[tex]8m > - 43 + 99[/tex]
[tex]8m > 56[/tex]

A triangle has a perimeter of 23 feet. Find the value of X
(4x – 5)(7 – 2x) – (2x + 2)(2 – 4x)= -1
Answer: x= 19/21.
Step-by-step explanation:
We can expand the expression to:
28x - 8x^2 - 35 + 10x -4x + 8x^2 - 4 + 8x = -1
We can then cancel the - 8x^2 and the + 8x^2 and simplify further by adding like terms:
38x - 35 + 4x -4 = -1 --> 42x - 39 = -1
We can then add 39 on both sides:
42x = 38
We can then divide both sides by the GCF (greatest common factor), 2:
21x = 19
We divide both sides by 21:
x = 19/21
Write an equation of the line that passes through the point (-6, -9) with slope-5.
A. y + 9 = 5(20+6)
B.y +6 = 5(x +9)
c.y+9= -5(x + 6)
D.y +6 = -5(x +9)
Answer:
[tex]y+9=-5(x+6)[/tex]
Step-by-step explanation:
We are being asked to write the equation in point-slope form:
[tex]y-y_1=m(x-x_1)[/tex] where m = slope and the first point = [tex](x_1,y_1)[/tex]
In this case, the slope is -5 and the point is [tex](-6,-9)[/tex] so the equation will be:
[tex]y+9=-5(x+6)[/tex]
