Question is the attachment
Answer:
180
^
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.
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.
a box in the shape of a rectangular prism has the dimensions shown. what length of the interior diagonal of the box? round to the nearest tenth.
100 cm
80 cm
60 cm
Answer:
I keep getting 141.421... so rounded it would be 141.4
Step-by-step explanation:
The length of the interior diagonal of the box is approximately 141.4 cm.
How to find the volume and base's area of a right rectangular prism?Suppose the base of the prism has length = l units, and width = w units.
Suppose that the height of the prism is of h units, then:
[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]
is the volume of that prism.
The base is a rectangle with length = L units, and width = W units, so its area is:
[tex]b = l \times w\: \rm unit^2[/tex]
We are given that;
Height= 100cm
Width=80cm
Length=60cm
Now,
Using the Pythagorean theorem, we can find the length of the interior diagonal as:
diagonal = sqrt(l^2 + w^2 + h^2)
diagonal = sqrt(100^2 + 80^2 + 60^2)
diagonal = sqrt(10000 + 6400 + 3600)
diagonal = sqrt(20000)
diagonal ≈ 141.4
Therefore, the length of the diagonal of prism will be 141.4

On the first day it was posted online, a music video got 1750 views. The
number of views that the video got each day increased by 20% per day. How
many total views did the video get over the course of the first 5 days, to the
nearest whole number?
To find the total views a music video got over the first 5 days with a 20% daily increase, calculate the views for each day using a geometric sequence formula and sum them, resulting in approximately 13023 views.
Explanation:To calculate the total views a music video got over the course of the first 5 days with a 20% daily increase starting at 1750 views, we use the geometric sequence formula V = V0 × (1 + r)n, where V0 is the initial number of views (1750), r is the daily increase rate (0.20), and n is the day number. The total views (TV) over 5 days is calculated by summing the individual daily views.
Day 1: 1750 views
Day 2: 1750 × (1 + 0.20) = 2100 views
Day 3: 1750 × (1 + 0.20)2 = 2520 views
Day 4: 1750 × (1 + 0.20)3 = 3024 views
Day 5: 1750 × (1 + 0.20)4 = 3628.8 views, rounded to 3629 views
The total views over the five days is the sum of daily views: 1750 + 2100 + 2520 + 3024 + 3629 = 13023 views.

A company manufactures handband a wirleless
Answer:
1. 21 represents the cost of manufacturing one handband.
3. The initial start up cost is $15000.
5. The company spends $57000 to manufacture 2000 handbands.
Step-by-step explanation:
We are given the cost function for manufacturing 'h' amount of handbands and it is provided that there was initial start up costs involved.
Now, as the cost function is given by, C(h) = 21h + 15000.
We can see that the initial start up cost is $15000.
As, 'h' is the number of handbands being made. So, 21h in C(h) is the cost of manufacturing 'h' handbands.
Therefore, 21 is the cost of manufacturing one handband.
Since, C(h) = 21h + 15000.
Substituting h = 2000, we get,
C(2000) = 21×2000 + 15000.
i.e. C(2000) = 42000 + 15000.
i.e. C(2000) = 57000.
The company spends $57000 to manufacture 2000 handbands.
Since, we are provided with only cost function, we can not talk about the profit.
Hence, option 1, 3 and 5 are correct.

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.

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]

What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Since, We know that;
An arc that lies outside of a central angle is called a major arc.
Since arc of a circle is a continuous portion of a circle.
And Central angle is the angle formed at the centre and it is an acute angle so, an arc that lies outside of a central angle will be a major arc only.
Because major arc is greater than half of the circle so, it can be formed outside of a central angle only.

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.
