The gallons of blue paint he needs to make the green paint is 6 gallons.
This is a problem in ratios. Let's look into what we know.
Volume of green paint needed = 10 gallons
Parts of blue paint needed = 3
Parts of yellow paint needed = 2
Total number of parts = parts of blue paint + parts of yellow paint
3 + 2 = 5
So fraction of blue paint needed = parts of blue paint / total parts
= 3/5
Volume of blue paint needed = [tex]\frac{3}{5}[/tex] × 10
= 6 gallons
Volume of yellow paint needed = [tex]\frac{2}{5}[/tex] ×10
= 4 gallons.
So we need 6 gallons of blue paint and 4 gallons of yellow paint to make 10 gallons of green paint.

what is the area of the shaded portion in the figure? If, it is a square and the lines are parts of a circle and the side of the square is 10 unit. Give answers in terms of pi.
A quarter-circle with a radius of 5 has the area: 25π/4, This is where the shaded area in the figure is located.
How do you calculate the size of a circle’s shaded sector?The area of a circle’s sector is calculated as /360o (r²), where r is the radius of the circle and is the angle of the sector.
The little, subtle distinctions between words are distinguished by shades of meaning. The terms “happy” and “ecstatic,” for example, both express emotion, but one is more powerful than the other. When students study shades of meaning, they learn how to effectively articulate how they feel or think. Shade is any gloomy place where sunshine or other strong light is obstructed. A shadow is a dark form that develops on a surface when an item blocks sunlight or other light.
The shaded area in the illustration is a quarter-circle with a radius equal to 10/2, or 5 units, or half the length of the square's side.
The following formula can be used to determine a circle's area:
A = πr²
If pi is present and r is the radius (approximately equal to 3.14).
A quarter-circle with a radius of 5 has the following area:
A = (π × 5²) / 4 = (π × 25) / 4 = 25π / 4
This is where the shaded area in the figure is located.

Is 1 2 a half or half?
Answer: half
Step-by-step explanation:
A circle is centered at O. The tangent to the circle at P is extended to Q. Line segment QS intersects the circle at R. Given that OS = 2, SR = RQ = 3, and PQ = 6, find the radius of the circle.
The radius of the circle will be [tex]\sqrt{22}[/tex].
In our question, we shall first extend QRS to the circle's point T.
According to the power of a point.
[tex]QP^{2}[/tex] = QR*QT
[tex]6^{2}[/tex] = 3*QT
QT = 12
Since QR = 3, RT = 9.
Since RS = 3, ST = 6.
Draw OT and OR, creating a triangle(TSO) and triangle(RSO).
OT and OR are radii, Let the radius be r.
Use the Law of Cosines on these two triangles.
OT2 = [tex]r^{2}[/tex] = [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)
OR2 = r2 = [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)
Since these are equal:
[tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO) = [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)
40 - 24*cos(TSO) = 13 - 12*cos(RSO)
Since angle(RSO) is supplementary to angle(TSO), cos(RSO) = - cos(TSO)
40 - 24*cos(TSO) = 13 + 12*cos(TSO)
27 = 36*cos(TSO)
0.75 = cos(TSO)
Since [tex]OT^{2}[/tex] = [tex]r^{2}[/tex] = [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)
[tex]r^{2}[/tex] = 40 - 24*0.75
[tex]r^{2}[/tex] = 22
r = [tex]\sqrt{22}[/tex]
Hence the radius of the given circle will be [tex]\sqrt{22}[/tex].

The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x.
Part a:
The value of the integral from 0 to 6 of f(x)dx is 16. This can be calculated using the Fundamental Theorem of Calculus (FTC) which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫f(x)dx = F(6) - F(0)
The anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫f(x)dx = (62 + 2*6) - (02 + 2*0) = 36 - 0 = 16.
Part b:
The value of the integral from 4 to 9 of g(x)dx is 20. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫g(x)dx = G(9) - G(4)
The anti-derivative of g(x) is G(x) = x3 + 3x2, so the value of the integral is:
∫g(x)dx = (93 + 3*9) - (43 + 3*4) = 729 - 168 = 20.
Part c:
The value of the integral from 4 to 9 of 2*g(x) - f(x)dx is 68. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫(2*g(x) - f(x))dx = 2*G(9) - F(9) - [2*G(4) - F(4)]
The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫(2*g(x) - f(x))dx = (2*(93 + 3*9) - (92 + 2*9)) - [2*(43 + 3*4) - (42 + 2*4)]
= (1854 - 19) - (544 - 16) = 1735 - 528 = 68.

Help me solve this triangle cuz im at 99
Answer:
Given: QR = QS (by given)
We are to prove: LS = ZR
Proof:
Since QR = QS, by the SAS (Side-Angle-Side) congruence postulate, we know that triangle QRS is congruent to triangle QSZ (both have two equal sides and included angle).
By the AAS (Angle-Angle-Side) congruence postulate, we know that if two angles of one triangle are congruent to two angles of another triangle, and the included side is congruent, then the two triangles are congruent.
Therefore, by using AAS congruence, we can say that triangle QRS is congruent to triangle QSZ.
By the CPCTC (Corresponding parts of congruent triangles are congruent), we know that if two triangles are congruent, then their corresponding sides are congruent.
Therefore, LS is congruent to ZR.
Therefore, we have proved LS = ZR
Note: The above proof uses the properties of congruence of triangles, if the student is not familiar with this, it might be challenging for them.

write an explicit rule for the sequence {-7,-1,5,11,17}. what is the position number for the term 47?
The position number for term 47 is 269.
This is an arithmetic sequence since each term has a common difference. Let us test it.
The difference between 1st and 2nd terms is
-7 + d = -1
d = -1 + 7
= 6
Now we check the difference for term
The difference between 3rd and 4th terms is
5 + d = 11
d = 11 – 5
= 6
So the difference is the same so we can apply a common equation for arithmetic sequence
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )
Where :
[tex]a_{n}[/tex] = number at term n
[tex]a_{1}[/tex] = first number of sequence
d = difference for each number sequence
n = term
From the question, we need to find the number at position term 47
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )
[tex]a_{47}[/tex] = -7 + 6 ( 47 - 1 )

On the left side, 10(3x + 2) becomes 30x + 20. On the right side, 7(2x − 4) becomes 14x − 28. After combining the like terms, the inequality becomes 30x + 20 > 14x − 28. Next, we must subtract 14x from both sides of the inequality. On the left side, 30x + 20 becomes 16x + 20. On the right side, 14x − 28 becomes −28. After subtracting 14x from both sides, the inequality becomes 16x + 20 > −28. Finally, we must subtract 20 from both sides of the inequality. On the left side, 16x + 20 becomes 16x. On the right side, −28 becomes −48. After subtracting 20 from both sides, the inequality becomes 16x > −48. To solve the inequality, we must divide both sides of the inequality by 16. On the left side, 16x becomes x. On the right side, −48 becomes −3. Therefore, the solution to the inequality is x > −3.
What is the equation
of the line that passes through the point (-6, 3) and has
slope of -4/3
y + 3 = (-4/3)(x - 6) is the equation of the line that passes through the point (-6, 3) and has slope of -4/3.
Define line?A line is an endlessly long object without breadth, depth, or curvature in geometry.Thus, despite the fact that they can exist in two, three, or higher dimensional environments, lines are one-dimensional things. The term "line" can also refer to a line segment that has two locations that serve as its ends in daily life.Straight lines have very little depth or width. You will learn about a variety of lines, including perpendicular lines, intersecting lines, transversal lines, etc. A figure in which two rays leave from the same point is called an angle.

For every one litre of water used to make medicine,199ml of sucrose and 271ml of saline solution are used. express the amount of water,sucrose and saline solution needed as a ratio in its simplest form.
The ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.
The amount of water, sucrose, and the saline solution used can be expressed as a ratio in its simplest form by finding the greatest common divisor (GCD) of the three quantities and dividing each by it.
1l of water = 1000 ml of water.
Let's find the GCD of the three quantities:
GCD(199,271,1000) = 1
So we can express the amount of water, sucrose, and saline solution needed as a ratio in its simplest form by dividing each of the three quantities by 1
Water : Sucrose : Saline solution = 1000 : 199/1 : 271/1 = 1000:199:271
Hence, the ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.

what is the positive and negative to this question
The positive and negative roots of the given quadratic graph are; -2 and 4.
What are the roots of the quadratic graph?We want to find the positive and negative roots of the quadratic graphs. Now, the general form of quadratic equations is expressed as;
y = ax² + bx + c
Now, for a quadratic graph, the roots are defined as the value of x where the curve crosses the x-axis.
In this given graph, we can see that the y-intercept which is the point at which the curve crosses the y-axis is at y = -8. We also see that the points at which the graph crosses the x-axis are at x = -2 and x = 4. This clearly shows that one root is positive and one root is negative.
Therefore from the two x-intercept values above as well as the y-intercept we got and when considering the type of roots that are being looked for, we can easily conclude that the positive and negative roots are as gotten above.
