120 Green, 60 Red
^ ^
Bruised Green = 30, Not Bruised Green = 90/Bruised Red = 12, Not Bruised Red = 48
Step-by-step explanation:
There is a beginning amount of 180 which goes in the first bubble. Then, you divide by 3 because 1/3 is red. 180 divided by 3 is 60, so there are 60 red apples. And 180 minus 60 is 120 and that's the amount of green. Then, 1/5 of the red apples are bruised so 60 divided by 5 is 12, so 12 are bruised and sincce 60 - 12 = 48, 48 are not. And then 1/4 of the green are bruised so 120 divided by 4 is 30, which means 30 are bruised. Lastly 120 minus 30 = 90, so 90 are not bruised that are green.

Please help me :( solve for x and y. y = 4x and 3x + 2y = 55
Final answer:
To solve the system of equations y = 4x and 3x + 2y = 55, you can substitute 4x for y in the second equation, simplify to find x = 5, and then calculate y = 20.
Explanation:
To solve for x and y using the equations y = 4x and 3x + 2y = 55, you can use substitution or elimination. Let's use substitution since we already have y expressed in terms of x.
Substitute 4x for y in the second equation: 3x + 2(4x) = 55.
Simplify and solve for x: 3x + 8x = 55 becomes 11x = 55, so x = 5.
Substitute x back into the first equation to find y: y = 4(5), so y = 20.
Therefore, the solution to the system of equations is x = 5 and y = 20.
A circle has its origin at (0, 0). The point (5, 7) is on the edge of the circle. What is the radius of the circle?
Select one:
A. r = 6√2
B. r = 2√18
C. r = 4√21
D. r = √74
E. There is not enough information to answer this question.
Answer:
The radius of the circle is √74
Step-by-step explanation:
Radius of a circle is the distance between the centre of a circle and its circumference.
The origin of the circle (0,0) will be its centre.
The point on the edge of the circle is the point on its circumference which is (5,7).
The radius of the circle will be the distance between this two points according to definition.
R = √(x2-x1)²+(y2-y1)²
Given (x1, y1) = (0,0) and (x2, y2) = (5, 7)
x1 = 0, y1 = 0, x2 = 5, y2 = 7
Substituting into the formula we have;
R = √(5-0)²+(7-0)²
R = √5²+7²
R = √25+49
R = √74
Answer:
Step-by-step explanation:
Given that a centre has an origin (0,0) and (5,7) at the edge.
What is the radius of the circle
This is a direct question, we can apply coordinate geometry by finding the distance between two point, .
From co-ordinate geometry, the distance between two points is
d =√[(x2-x1)² + (y2-y1)²]
So, applying this
Point 1 = (x1,y1) = (0,0)
Point 2 = (x2,y2) = (5,7)
The radius of the is
r = √[(x2-x1)² + (y2-y1)²]
r = √[(5-0)² + (7-0)²]
r = √[5² + 7²]
r = √(25 + 49)
r = √74

Explain how to determine if a question is asking for
volume or surface area.
Answer:
Sample response: Volume represents the amount of space an object takes up. Surface area represents the area of the outside surface of the object. If you need to find the amount of space something takes up, or the amount to fill something, find the volume. If you want to find how much is needed to cover something, find the surface area.
Step-by-step explanation:
If they are asking for volume, they are wanting to know how much can go inside the object....If they are asking for surface area.....the are wanting to know about the outside only.
The volume is equal to the product of area and height of shape.
The total area occupied by the surfaces of an object is called its surface area.
What is a volume?"A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere."
What is surface area?"The total area occupied by the surfaces of an object is called its surface area."
Different shapes have different volumes. In 3d geometry, we have studied the various shapes and solids such as cube, cuboid, cylinder, cone, etc., that are defined in three dimensions. For all these shapes, we are going to learn to find the volume.
The formula to calculate the volume of a solid in a three-dimensional space, is to find the product of dimensions. Basically, the volume is equal to the product of area and height of shape.
Volume = Base Area x Height
For shapes having flat surfaces such as cube and cuboid, it is easy to find the volume. But for curved shapes like cone, cylinder and sphere, we have to consider the dimensions of its curved surface as well, such as radius or diameter.
In geometry, different 3D shapes have different surface areas which can be easily calculated using the formulas that we will be learning in this article. The surface area is classified into two categories:
1. Lateral surface area or Curved surface area
2. Total surface area
There is a different surface area formula for every geometrical shape, but the idea behind all is to get the total area occupied by all the faces of the objects.
The total surface area considers all the faces of the 3D shape including the flat surfaces and the curved surfaces, while the lateral surface area is calculated to find the area occupied by the curved surface of the shape. It does not include the area of the bases. A sphere is one 3D figure which has only one round surface with no flat base.

Consider the diagram below. What is the mDEB?
Answer:146
Step-by-step explanation:
The measure of the arc DEB is equivalent to 146°.
What is angle?An angle is formed when two rays have the same end point. The common end point is called vertex.
Given is to find the measure of arc DEB.
We can write the measure of angle DBE as half the measure of arc BCD. Mathematically, we can write -
∠DBE = 1/2(arc BCD)
107 = 1/2(arc BCD)
arc BCD = 107 x 2
arc BCD = 214°
Now, we can write -
m(arc DEB) + m(arc BCD) = 360°
m(arc DEB) = 360 - 214
m(arc DEB) = 146°
Therefore, the measure of the arc DEB is equivalent to 146°.

A bag contains 10 red marbles and 15 green marbles. If yuki selects a marble from the bag without looking,what is the probablity that she will pull out a res marble?
Answer:
1/25
Step-by-step explanation:
The probability is 1/25 because 10 red marbles plus 15 green marbles = 25 marbles in total. Therefore, the probability of choosing a red marble without looking is 1/25.
Answer:
The probability that Yuki will pull out a red marble is [tex]\( \frac{2}{5} \)[/tex].
Explanation:
To find the probability of selecting a red marble, you divide the number of red marbles by the total number of marbles in the bag.
Given:
- Number of red marbles = 10
- Number of green marbles = 15
Total number of marbles = Number of red marbles + Number of green marbles
Total number of marbles = 10 + 15 = 25
Now, to find the probability of selecting a red marble:
[tex]\[ \text{Probability} = \frac{\text{Number of red marbles}}{\text{Total number of marbles}} \][/tex]
[tex]\[ \text{Probability} = \frac{10}{25} \][/tex]
[tex]\[ \text{Probability} = \frac{2}{5} \][/tex]

The height of a cylinder is 12 inches and the radius is 3.5 inches. What is the approximate volume of the cylinder?
Answer:
V≈461.81in³ That is the answer!
V = pi*r^2*h
V = pi*(3.5)^2*12
V = pi*12.25*12
V = pi*147
V = 147pi .... exact volume in terms of pi
V = 461.8141200777 is the approximate volume (use a calculator here)
The units for the volume are in cubic inches
Side note: If you use pi = 3.14, then you'll get an approximate volume of 147*pi = 147*3.14 = 461.58 which is a bit off from the other value we got earlier due to the fact pi = 3.14 is not as accurate as using the calculator's internal value of pi.

Two sides of a trangie measure 5 in and 12 in which could be the length of the third side?
Answer:
The length of the third side could be anywhere between [tex]7\; \rm in[/tex] and [tex]17\; \rm in[/tex], excluding the two endpoints.
Step-by-step explanation:
Let [tex]x[/tex] represent the length (in inches) of the third side.
In a triangle, the sum of the lengths of any two sides should be greater than the length of the third side. The lengths of the three sides of this triangle are:
[tex]5\; \rm in[/tex], [tex]12\; \rm in[/tex], and[tex]x\; \rm in[/tex].The sum of the lengths of the first two sides is [tex]5 + 12 = 17\; \rm in[/tex]. This sum should be greater than (not equal to) the length of the third side: [tex]x\; \rm in[/tex]. That gives the first inequality:
[tex]5 + 12 > x[/tex].Similarly, the sum of the lengths of the first and the third sides is [tex](5 + x)\; \rm in[/tex]. This sum should be greater than (not equal to) the length of the second side: [tex]12\; \rm in[/tex]. That gives the second inequality:
[tex]5 + x > 12[/tex].The sum of the lengths of the second and the third sides is [tex](12 + x)\; \rm in[/tex]. This sum should be greater than (not equal to) the length of the first side: [tex]5\; \rm in[/tex]. That gives the third inequality:
[tex]12 + x> 5[/tex].Solve the three inequalities for the range of [tex]x[/tex], the length of the third side:
[tex]\displaystyle \left\lbrace\begin{aligned}& 5 + 12 > x \\ & 5 + x > 12 \\ & 12 + x > 5\end{aligned}\right.[/tex].
The first inequality simplifies to [tex]x < 17[/tex]. The second inequalities gives [tex]x > 7[/tex], while the third gives [tex]x > -7[/tex].
Refer to the diagram attached. [tex]7 < x < 17[/tex] is the region that satisfies all three inequalities. Therefore, the length of the third side should be between [tex]7[/tex] and [tex]17[/tex], exclusive.
