Answer:
529.875 [tex]cm^3[/tex]
I don't know if they want it rounded or not, but rounded it would be 529.88 or 529.9
Step-by-step explanation:
Find the volume of the can (cylinder):
h = 12 cm
d = 7.5 cm
r = 1/2d = 3.75 cm
[tex]V=\pi r^2h\\\\= (3.14)(3.75)^2(12)\\\\= 529.875[/tex]
A business shipped 106 packages one day. Customers are charged 4.50 for each standard delivery and 7.50 for each express delivery
The question is incomplete:
A business shipped 106 packages one day. Customers are charged 4.50 for each standard delivery and 7.50 for each express delivery. Total shipping charges for the day were $600.00. How many of each kind of package were shipped?
Answer:
The business shipped 65 standard delivery packages and 41 express delivery packages.
Step-by-step explanation:
Since the business shipped 106 packages one day you can say that:
x+y=106, where:
x is the number of standard delivery packages
y is the number of express delivery packages
Also, you can say that the result of multiplying the price per each type of package for its amount and adding those would be equal to the total shipping charges for the day, which is:
4.50x+7.50y=600
So, you have the following equations:
x+y=106 (1)
4.50x+7.50y=600 (2)
Now, you can solve for x in (1):
x=106-y (3)
Then, you can replace (3) in (2) and solve for y:
4.50(106-y)+7.50y=600
477-4.50y+7.50y=600
3y=600-477
3y=123
y=123/3
y=41
Finally, you can replace the value of y in (3) to be able to find the value of x:
x=106-41
x=65
According to this, the answer is that the business shipped 65 standard delivery packages and 41 express delivery packages.
Select all correct ways of factoring –3x – 9.
Answer:
Some possible expressions, since there's no answer choices provided:
-3(x + 3)
3(-x - 3)
Step-by-step explanation:
Expression 1:
This uses a GCF of -3, since -3x and -9 are divisible by this. Let's divide -3x and -9 by this first:
-3x / -3 = x
-9 / -3 = 3
So now, we can add these terms and multiply them by -3 to get our answer:
-3(x + 3)
And just to check, we can expand it:
-3x + -3(3) = -3x - 9
Expression 2:
This uses a GCF of 3, like the last one but it's negative. -3x and -9 are also divisible by this. Let's divide both terms by this GCF first:
-3x / 3 = -x
-9 / 3 = -3
Now, we can add these terms and multiply them by -3 to get our final answer:
3(-x - 3)
To check, once again:
-3x + 3(-3) = -3x - 9

Find all the zeroes of polynomial 2x4
– 9x3 + 5x2 + 3x – 1 ,if two of its zeroes are 2 + √3 & 2 - √3
9514 1404 393
Answer:
x ∈ {-1/2, 1, 2-√3, 2+√3}
Step-by-step explanation:
The given zeros mean that one of the quadratic factors of the given polynomial is ...
(x -2)^ -3 = x^2 -4x +1
When that is factored out (see first attachment), the remaining quadratic is ...
2x^2 -x -1
This can be factored as ...
= (2x +1)(x -1)
which has roots that make these factors zero: x = -1/2, x = 1.
So, all of the zeros of the given polynomial are ...
-1/2, 1, 2-√3, 2+√3 . . . all zeros

Additional comments
When p is a zero of a polynomial, (x-p) is a factor of it. The given zeros mean that factors are (x-2-√3) and (x-2+√3). The product of these factors is the difference of the squares (x-2)^2 and (√3)^2, so is (x -2)^2 -3.
Using the pattern for the square of a binomial, we see this is ...
(x-2)^2 = x^2 -2·2x +2^2 = x^2 -4x +4
The product of the given factor is then 3 subtracted from this square. The given zeros mean there is a quadratic factor of ...
(x-2-√3)(x-2+√3) = (x-2)^2 -3 = x^2 -4x +4 -3 = x^2 -4x +1

a line with a slope of 1 passes through the point (5,10). what is the equation in this slope-intercept form?
Answer:
y=x+5
Step-by-step explanation:
So first you need to plug everything into the point-slope formula which is
y-y1=m(x-x1)
m being the slope and y1 and x1 being the point (5,10)
So once you plug it in it should look like this: y-10=1(x-5)
Now you solve it
First you need to distribute 1 in 1(x-5) which is (x-5)
Now you have y-10=x-5
Then you add 10 to both sides which is y=x+5
Your answer is y=x+5

Describe, in words, the process you would use to find w.
Answer:
w = 52°
Step-by-step explanation:
We know that the sum of the angle of a triangle is equal to 180 degrees
In this figure,
w+w+76 = 180
As w = w (Vertically opposite angles)
So,
2w = 180-76
2w = 104
w = 52
So, the value of w is equal to 52°.

Which of the equations below shows the relationship in the table?
Answer:
Im Sure its A
Step-by-step explanation:
The population of Indiana showed an annual growth rate of 0.6% between 1998
and 1999. The population in 1999 was approximately 273,000,000. Based on this
model, find the population in 2007.
The population of Indiana in 2007 can be estimated by using the annual growth rate of 0.6% between 1998 and 1999 and the population in 1999, which was approximately 286,485,882.
To find the population in 2007, we need to calculate the growth from 1999 to 2007. We can do this by multiplying the population in 1999 by 1 plus the growth rate raised to the power of the number of years between 1999 and 2007.
Let's calculate step by step:
1. Calculate the number of years between 1999 and 2007: 2007 - 1999 = 8 years.
2. Calculate the growth rate per year: 0.6% = 0.006.
3. Calculate the population in 2007: 273,000,000 * (1 + 0.006)^8 = 273,000,000 * 1.048834 = 286,485,882 (approximately).
Therefore, based on this model, the population of Indiana in 2007 would be approximately 286,485,882.

A sphere with diameter of 12 cm is being painted. How much more paint is now needed to paint the sphere that has four times the original diameter.
4 times more paint
B 8 times more paint
16 times more paint
D 64 times more paint
Answer:
64 times more paint will be needed since the volume of the second is 64 times the volume of the first
Step-by-step explanation:
If the original sphere is 12 cm diameter
its radius will be half this measure which is 12/2 = 6 cm
The new diameter is 4 times this, so its radius would be 4 times this and it is 24 cm
Now, the volume of the sphere means we have to raise the power of the radius by 3
The other terms in the formula remains the same for both, so we are simply comparing the radii
so we will have the difference in volume in times of multiples as ;
(24/6)^3 = 4 * 4 * 4 = 64

7. A rectangular prism measures 7 1/2 cm by 12 cm by 15 1/2 cm. a. Calculate the number of cubes with edge length cm that fit in this prism. b. What is the volume of the prism in cm3? Show your reasoning. If you are stuck, think about how many cubes with -cm edge lengths fit into .
Answer:
a.The number of cubes with edge length 1/2 cm that fit in this prism= 2520
b. Volume of the prism= 315 cm³
Step-by-step explanation:
Volume of the rectangular prism = length *width * height
= 7 1/2 * 12 * 15 1/2
= 7 * 6* 15 1/2
= 7*3*15
= 315 cm³
Volume of the cube = length *width * height
= 1/2 *1/2 *1/2
= 1/8 cm³
Now number of cubes that would fit in the rectangular prism is given by
= Volume of the prism/ Volume of the cubes
= 315/1/8
= 2520
The number of cubes with edge length cm that fit in this prism= 2520
The lengths of the sides of the triangle are 3, 8, and 10. Is the triangle a right triangle, acute triangle, or an obtuse triangle?
Answer:
Obtuse
Step-by-step explanation:
You have to make sure it is a triangle by adding the smallest and the medium sides, if the result is greater than the bigger side then it is a triangle. you then use the Pythagorean theorem to check if the triangle is a right triangle, acute, or obtuse. If [tex]c^{2}[/tex] = [tex]a^{2} +b^{2}[/tex] then it is a right triangle. If [tex]c^{2} >a^{2} + b^{2}[/tex] then it is an obtuse triangle. if [tex]c^{2} < a^{2} +b^{2}[/tex] then it is an acute triangle. [tex]10^{2}[/tex] _ [tex]3^{2} + 8^{2}[/tex] 9+64_100 70_100 70<100in this case [tex]c^{2}[/tex] is greater than [tex]a^{2} +b^{2}[/tex] therefore, is it an obtuse triangle.
