Answer:
Because they are in the ratio 2:3 we'll call red and blue paint 2x and 3x respectively. We know that there are 15 liters of blue paint which means that 3x = 15. Solving for x we get x = 5. Since red paint is denoted by 2x it would be 2 * x = 2 * 5 = 10.
Answer:
10 liters
Step-by-step explanation:
Red : Blue
2 3
We want 15 blue liters
15/3 = 5
Multiply each term by 5
Red : Blue
2*5 3*5
10 : 15
The length of the unknown slide is?
Answer: 10.8
Step-by-step explanation:
We can use the Pythagorean Theorem to solve this.
a^2 + b^2 = c^2
6^2 = 36
9^2 = 81
36 + 81 = 117
square root of 117 is 10.8

Aubrey used 4/7 liters of paint for a mural in her room and 2/10 liter for a wall in her bathroom. Determine a reasonable estimate for the total amount of paint Aubrey used.
Answer:
27/35 is the exact answer
7/10 is an estimate
Step-by-step explanation:
4/7+2/10
Simplify the fraction
4/7+1/5
The common denominator is 35
4/7*5/5 + 1/5 *7/7
20/35 + 7/35
27/35
To estimate
4/7 is close to 1/2
2/10 is close is 1/5
1/2 + 1/5 =
5/10 + 2/10 = 7/10

Definitions of ASA SAS AAS, can someone dumb it down plz?
Answer:
Hope this helps.
Step-by-step explanation:
So for ASA, the two triangles have to have two angles congruent, and in the middle of those angles, they have to have a line that's congruent.
For SAS, the two triangles have to have two lines congruent, and in the middle of those lines, they have to have an angle that's congruent.
For AAS, the two triangles have to have two angles congruent, but the line that's congruent has to be on the side, not in the middle.

City Donuts recently sold 12 donuts, of which 6 were maple donuts. What is the experimental probability that the next donut sold will be a maple donut?
Simplify your answer and write it as a fraction or whole number.
P(maple donut) =
Answer:
1/2
Step-by-step explanation:
Out of a total 12 donuts, 6 of them are maple. Assuming this ratio stays constant, the experimental probability that the next one sold is a maple donut is 6/12=1/2. Hope this helps!
Answer:
P(maple donut) = 0.5
Step-by-step explanation:
If they sold 12 donuts, of which 6 of them were Maple Donuts.
The experimental probability of donuts sold that were maple donuts is:
[tex]\frac{6}{12}=\frac{1}{2}=0.5[/tex]
Therefore donuts sold in the future, would follow this probability, so our answer is 0.5.

Which represents a function
When you flip a biased coin the probability of getting a tail is 0.75.
How many times would you expect to get tails if you flip the coin 160 times?
Answer:
You would expect to get tails 120 times
Step-by-step explanation:
0.75 * 160 = 120
Answer:
120
Step-by-step explanation:
to find the number of times, you expect to get tails:
multiply 160 by 0.75.
you could also multiply 160 by 3/4, which is easier, but still gives the same answer.
3/4 x 160 = 3 x 40 = 120

Answer:
10/9
Step-by-step explanation:
average rate of change in 0≤x≤9
=(3-(-7))/(9-0)=10/9
Answer:
The solution is 10/9
Step-by-step explanation:
Step 1: identify the right approach:
Given a function g(x) over a period of time, to find the average rate of change of g(x) over this period of time, we divide the change in g(x) by the change in x.
Step 2: Perform the calculation:
As shown in picture,
x = 0 => g(x) = -7
x = 9 => g(x) = 3
=> The change of x over interval [0, 9] is:
x_change = 9 - 0 = 9
=> The change of g(x) over interval [0, 9] is:
g(x)_change = 3 - (-7) = 10
=> The average rate (r) of change of g(x) over interval [0, 9] is:
r = g(x)_change/x_change = 10/9
Hop this helps!

HELP I CAN’T FIND THE EQUATION FOR N
I realized the output is -5 each, but what’s the equation ;-;;;l
Answer:
5th term of sequence = -18
nth term of the sequence = -5n + 7
Step-by-step explanation:
Difference between successive and previous term of the output,
[tex]T_{2}-T_{1}[/tex] = -3 - 2
= -5
Similarly, [tex]T_{3}-T_{2}=-8-(-3)[/tex]
= -5
There is a common difference 'd' = (-5)
Therefore, the sequence formed will be an arithmetic sequence.
First term of the sequence 'a' = 2
Explicit formula of an arithmetic sequence, [tex]T_{n}[/tex] = a + (n - 1)d [n = input value]
[tex]T_{n}[/tex] = 2 + (n - 1)(-5)
= 2 - 5n + 5
= -5n + 7
5th term of this sequence,
[tex]T_{5}=2+(5-1)(-5)[/tex]
= 2 - 20
= -18
Therefore, 5th term of sequence = -18
nth term of the sequence = -5n + 7

Answer:
[tex]48 \: \: degrees[/tex]
Answer B is correct
Step-by-step explanation:
We know that,
Angels in a straight line = 180°
Let's get the ratio of angles as,
[tex] 4x: 11x[/tex]
Let's solve for x now.
[tex]4x + 11 = 180 \\ 15 = 180 \\ \frac{15x}{15} = \frac{180}{15} \\ x = 12 \\ [/tex]
Angle AOB = 4x
[tex]x = 12 \\ 4x = 12 \times 4 \\ = 48[/tex]

Find the volume of the prism.
I need this for my notes so i can know what to do. What is the length of AC? And Length of AB?
Answer:
AC 5
AB = 3
Step-by-step explanation:
AC = distance between the points
C-A = 3 - -2 = 3+2 = 5
The distance is 5
AB = distance between the points
B-A = 1 - -2 = 1+2 = 3
The distance is 3
Answer:
AC = 5
AB = 3
Step-by-step explanation:
AC:
3 - X = -2
3 - 5 = -2
AB:
1 - X = -2
1 - 3 = -2
Penny had a bag of marbles. She gave one-third of them to Rebecca, and then one-fourth of
the remaining marbles to John. Penny then had 24 marbles left in the bag. How many marbles were
in the bag to start with?
pls explain.
Given That:
x - (Rebecca's share + John's share) = 24
x - (x/3 + x/4) = 24
12x/12 - (4x / 12 + 3x / 12) = 24
5x/12 = 24
5x = 24 x 12
5x = 288
x = 57 or 58

Which of the following linear equations corresponds to the table above?
The linear equation of the corresponding table is y = 4x+3 which is correct option(D).
What is the slope of a linear function?The slope of a linear function is defined as the angle of the line. It is denoted by m.
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a linear function —Point 1 and Point 2. Point 1 has coordinates (x₁, y₁) and Point 2 has coordinates (x₂, y₂)
We need two of those points to come up with the equation of the corresponding line.
Solution in y-intercept form y = mx+b
We can calculate the slope of the line using any 2 of the given points: I pick (0,3) and (3,15).
The formula for determining the slope of the line through 2 points (x₁,y₁) and (x₂,y₂) as m=(y₂-y₁)/(x₂-x₁)
By plugging in the corresponding values,
m = (15-3)/(3-0) = 12/3 = 4
Since the value of y when x is zero, i.e. the point (0,3) of the table, then the value of b is 3.
Now, Substitute the values in y = mx+b,
y = 4x+3
Hence, the linear equation of the corresponding table is y = 4x+3.

Solve each. Show all necessary work.
8. Write the equation of the line in slope-intercept form that passes through (10.21) and (15.36)
Answer:
y = 3x - 9
Step-by-step explanation:
First, find the slope using y2 - y1 / x2 - x1
36 - 21 = 15
15 - 10 = 5
15/5 = 3, so the slope (m) is 3.
Now, plug into point-slope form: y - y1 = m (x - x1)
y - 21 = 3 (x - 10)
Simplify
y - 21 = 3x - 30
y = 3x - 9

What are the limits of mathematics?
math, a limit is defined as a value that approximates the output of the specified input value of the function. Limits are important in calculus and mathematical analysis and are used to define integrals, derivatives, and continuity. In mathematics, the limit is the value that the function approaches when the input approaches a particular value.
Boundaries are essential for calculus and mathematical analysis and are used to define continuity, derivatives, and integrals. 1a: What separates, limits, or limits the age limit for junior golf. b: I pushed her body to the limit. 2a: Geographical or political boundaries. b Plural borders: Surrounded by borders: The border to the northern border they came from-John Milton.
