Answer:
45
Step-by-step explanation:
There are 45 total marbles. The probability of drawing a yellow marble on the first draw is 3/4. Given replacement, the probability on the second draw is the same as on the first draw, so the probability of black marble on the second draw is 6/14. The probability of drawing first a yellow marble then a black marble is 3/14 * 6/14 = 18/196.

Use the information given to enter an equation in standard form. (−1, 1) and (0, 6) are on the line.
Answer: -5x+y=6
Step-by-step explanation:
Given
Points on line [tex](-1,1)\ \text{and}\ (0,6)[/tex]
The standard form of an equation is [tex]ax+by=c[/tex]
Using the two-point form of a line
[tex]\Rightarrow \dfrac{y-1}{x+1}=\dfrac{6-1}{0+1}\\\Rightarrow \dfrac{y-1}{x+1}=\dfrac{5}{1}\\\Rightarrow y-1=5x+5\\\Rightarrow y-5x=6\\\Rightarrow -5x+y=6[/tex]
What is the area of the following circle?
Either enter an exact answer in terms of it or use 3.14 for it and enter your answer as a decimal.
R = 5
Answer:
78.54
Step-by-step explanation:
The area of a circle can be found using
[tex]A=\pi r^2[/tex]
If we know that the radius is 5, then our equation becomes this.
[tex]A=\pi*5^2[/tex]
Simplifying:
[tex]A=3.14*25[/tex]
Gives us:
[tex]A=78.54[/tex]
Which of the following equations corresponds to the graph below
Answer:
d) y = -1/2 + 3
Step-by-step explanation:
Looking at the graph, we can use y = mx + b to find the equation. m is the slope and for slope, we go 1 unit down and 2 units to the right. b is the y variable and our b would be 3.
y = mx + b
y = -1/2x + 3
Hope this helps and stay safe, happy, and healthy, thank you :) !!
Pls answer quick if you don’t mind.
Answer:
A
Step-by-step explanation:
if x=19, 19x3 =57 and 57+123=180 and straight angle = 180 so A
Answer:
X=19
Step-by-step explanation:
123 and 3x are supplementary/they equal 180 added together.
Let's solve your equation step-by-step.
123+3x=180
Step 1: Simplify both sides of the equation.
3x+123=180
Step 2: Subtract 123 from both sides.
3x+123−123=180−123
3x=57
Step 3: Divide both sides by 3.
3x/3 = 57/3
x=19
Have a splendid day.

What is the length of the missing leg?
Answer:
6
Step-by-step explanation:
[tex]\sqrt{10^{2} -8^{2} }[/tex] = 6
Answer:
b = 6
Step-by-step explanation:
Pythagorean formula:
a² + b² = c²
Work:
a² + b² = c²
8² + b² = 10²
64 + b² = 100
b² = 100 - 64
b² = 36
[tex]\sqrt{b^2} =\sqrt{36}[/tex]
b = 6

CAN SOMEONE PLEASE HELP MEEEE!!!! I’ll give extra points
Answer:
35/37
Step-by-step explanation:
In this question, we are to calculate the ratio that represents the cosine of angle O
Firstly, please check the attachment for the diagram of the triangle.
Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse
The hypotenuse is the longest length which is 37 which represents the length ON
The side adjacent to angle O is the side OP which is 35
Thus, the ratio representing the cosine of angle O is 35/37

plz help me check if its right its kinda hard :(
Answer:
It is correct actually.
Step-by-step explanation:
141 + 39 = 180
Yeah, that's correct
Explanation: Supplementary angles add to 180 degrees. If angle R is 39 degrees then angle S has to be 141 degrees because 39 + 141 = 180.
everyday marco puts $0.25 into a jar for savings. one day he counted his money and found he had $91.75. how many days had he been saving?
Answer:
Marco had been saving for 367 days.
Step-by-step explanation:
If Marco started with no money and put $0.25 into a jar a day, then you just have to divide the total amount of money he has by 0.25.
91.75/.25 = 367
True or false questions for the following graph:
will brainlist if correct! ( if your a scammer i will report!)
- true or false; the ordered pair (2, 2) is a root of the graph.
- true or false; the domain of the graph is all real numbers.
- true or false; the range is y < 2.
- true or false; the graph has a minimum point at (2,2)
9514 1404 393
Answer:
falsetruefalsefalseStep-by-step explanation:
The roots (zeros) of the function are (1, 0) and (3, 0). The point (2, 2) is the vertex, the maximum in this case.
The domain of any polynomial function is "all real numbers".
The range is y ≤ 2, not y < 2.
6v+12b=504
2v+5b=204
Answer:
Step-by-step explanation:
6v + 12b = 504 eq1
2v + 5b = 204 eq2
6v + 15b = 612 eq2 times 3
0 -3b = 504 - 612 subtraction of the two bolded eqs
-3b = -108 solve for b
b = 36
Another way to solve the problem
6v + 12b = 504 I would eliminate the v term by multiplying the bottom
2v + 5b = 204 equation by -3 on BOTH sides and then add the two eqs
2v + 5b = 204
-3(2v + 5b) = -3(204)
-6v - 15b = -612
6v + 12b = 504
-6v - 15b = -612 add the like terms
(6v + (-6v)) + (12b + (-15b) = 504 + (-612)
(6v -6v)) + (12b - 15b) = 504 - 612)
0 + -3b = - 108 solve for b divide both sides by -3
b = -108/-3
b = 36
use eq 2v + 5b = 204 to solve for v and knowing b = 36
2v + 5b = 204 b=36
2v + 5(36) = 204 substract 5 times 36 from both sides
2v = 204 - 180
v = 24 / 2
v = 12
NOW CHECK the values for b and v using the OTHER eq
6v + 12b = 504
6(12) + 12(36) = 504
72 + 432 = 504
504 = 504 IT CHECKS

Someone help me it’s a timed question only get 3 min
Answer:
Slope = -5/4
y-intercept = 7
Step-by-step explanation:
The equation is y = mx + b.
m is the slope, while b is the y-intercept.
Because -5/4 is where m would be in the equation, it is the slope.
7 is where b would be in the equation, so it is the y-intercept.
A comapny's stock was selling 16$ a share. A month later it was selling at 20$ a share. What is the percentage gain?
Answer: 25%
Step-by-step explanation:
Given
Initial Cost of share [tex]C.P.=16\$[/tex]
After a month, its selling price is [tex]S.P.=20\$\ \text{per share}[/tex]
The gain percentage is given by
[tex]\Rightarrow \text{Gain }\ \%=\dfrac{\text{S.P.-C.P.}}{\text{C.P.}}\times 100[/tex]
[tex]\Rightarrow \text{Gain}\ \%=\dfrac{20-16}{16}\times 100=25\%[/tex]

Cora uses 9.5 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls
Answer:
5.7 pints
Step-by-step explanation:
Total pints of paint used = 9.5 pints
Fraction of blue paint used = 2/5 ; while the rest is white paint
Amount od blue paint used :
2/5 * 9.5 = 3.8 pints
Amount of white paint used :
Total pints - blue pints used
9.5 pints - 3.8 pints
= 5.7 pints of white paint.

Answer:
dogs = 2
cats = 80
Step-by-step explanation:
Here I will assume that cats and dogs are proportional
c = y d, if you substitue, you get
10 = y 4, which rearranged, becomes
y = 10/4 = 2.5
now that we know y, we can work out x and y, the missing dogs and cats
4 = 2.5 d
here, dogs = 2
c = 2.5 * 32
2.5 * 32 = 80
here, cats = 80

what is Arithmetic progression and geometric progression?
hope u have a great day!!
Answer:
Arithmetic progression is a series of numbers in which each one varies from the one before it by a constant quantity
Geometric progression is a non-zero number sequence in which each term after the first is found by multiplying the previous term by a fixed, non-zero number known as the common ratio.
Hope you have a good day as well! <3
