Answer:
A good combination will be equal to or greater than 80 ft³. Example
r = 3 ft
h = 5 ft
volume = πr²h
volume = 3.14 × 9 × 5 = 3.14 × 45 = 141.3 ft³ is a good combination of radius and height .
Step-by-step explanation:
The volume of a cylinder = πr²h
Jeff is planning on building a cylindrical water tank that has a capacity of no less than 80 ft³. This means he want the volume of the cylindrical tank to be equal to or greater than 80 ft³(volume ≥ 80 ft³). The combinations of radius and height should be equal to or greater than 80 ft³ when they are inserted in the volume formula of a cylindrical water tank.
For example
volume = πr²h
r = 2 ft
h = 5 ft
volume = πr²h
volume = 3.14 × 2² × 5 = 62.8 ft³ is not a good combination of base radius and height because the volume is less than 80 ft³.
A good combination will be equal to or greater than 80 ft³. Example
r = 3 ft
h = 5 ft
volume = πr²h
volume = 3.14 × 9 × 5 = 3.14 × 45 = 141.3 ft³ is a good combination of radius and height .
What is the value of x in the equation -2/3x + 9 = 4/3x - 3 ?
Answer:
x = 1/6
Step-by-step explanation:
hope it helps.
x= 1/6
Answer: 6
Step-by-step explanation:
[tex]-\frac{2}{3}x+9=\frac{4}{3}x-3[/tex]
Subtract [tex]\frac{4}{3}x[/tex] from both sides to leave variables on the left.
[tex]-\frac{4}{3}x-\frac{2}{3}x+9=\frac{4}{3}x-3-\frac{4}{3}x[/tex]
[tex]-\frac{4}{3}x-\frac{2}{3}x+9=-3[/tex]
Now subtract 9 from both sides to isolate independent variables on the right.
[tex]-\frac{4}{3}x-\frac{2}{3}x+9-9=-3-9[/tex]
[tex]-\frac{4}{3}x-\frac{2}{3}x=-3-9[/tex]
Combine like terms;
[tex]-\frac{6}{3}x=-12[/tex]
Simplify;
[tex]-2x=-12[/tex]
To completely isolate x, divide by -2
[tex]\frac{-2x}{-2}=\frac{-12}{-2}[/tex]

Answer:
B
Step-by-step explanation:
25x² - 144 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b), thus
25x² - 144
= (5x)² - 12²
= (5x + 12)(5x - 12) → B
Answer:
B) ( 5x + 12 ) ( 5x - 12 )
Step-by-step explanation:
Since we have options we could try expanding all of them out.
A) ( 12 + 5x ) ( 12 - 5x )
144 - 60x + 60x - 25x² = 144 - 25x²
That's not the answer we are looking for so we cross out "a" as an option
B) ( 5x + 12 ) ( 5x - 12 )
25x² - 60x + 60x - 144 = 25x² - 144
This is the answer which we are looking for so B is the answer

Here is the equation of a circle in standard form.
(x + 10)2 + (y + 9)2 = 100
What is the radius?
A. 100
B. 50
C. 10
Answer:
C
Step-by-step explanation:
The equation is in the standard form for a circle:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
If we compare the 2 equations:
(x-h)^2+(y-k)^2=r^2
(x + 10)2 + (y + 9)2 = 100
We can see that r^2 is equal to 100. Let's set them equal to each other.
r^2=100
Since r is being squared, take the square root of both sides. This will cancel out the exponent.
[tex]\sqrt{r^2}=\sqrt{100}[/tex]
r=10
So, our radius is 10, or choice C

A company wants to increase the 10% peroxide content of its product by adding pure peroxide (100% peroxide). If x liters of pure peroxide are added to 100 liters of its 10% solution, the concentration, C, of the new mixture is given by the formula below. How many liters of pure peroxide should be added to produce a new product that is 70% peroxide? C= (x + 0.1(100))/(x +100)
Answer:
200 liters.
Step-by-step explanation:
To solve this, let's first set C in our equation to .7, since that is the concentration we are aiming for.
.7= [tex]\frac{(x+0.1(100))}{x+100}[/tex]
Next, we can simply this equation further:
.7= [tex]\frac{(x+10)}{x+100}[/tex]
We can multiply both sides by the denominator, resulting in:
.7x+70= x+10
Finally, continue simplifying to solve for x:
60= .3x
x= 200 liters.

Monica sells lemonade over the summer and uses conical paper cups to serve the lemonade. Each cupis ퟖcentimeters in diameter and ퟏퟏcentimeters tall. She starts with a ퟏퟎ-gallon container (one gallon is equivalent to ퟑퟕퟖퟓ풄풎ퟑ)
Answer:
Part A Answer = 206
Part B Answer= 5
Step-by-step explanation:
Part A Explanation:
The formula for volume of a cone is V=(1/3) pi*r^2 h
So then you plug in. V= 1/3 pi (4)^2(11)
You get the radius by dividing the diameter by 2
When you multiply it all it becomes 184.31cm^3 (Save this for later on in this Part A question)
Now we have to find the Volume of the cooler. That would be: 10*3785=37850 Since there were 10 gallons and each gallon is 3785 cm^3 you multiply them together.
Then you divide the volume of the cooler by the volume of the cone cup: 37,850/184.31=205.36 but since you cannot have 205.36th of a cup you need to get another one since 205 would not be enough giving us a total of 206 cups.
Part B explanation: Since there are 50 cups per package you would have to divide 206 by 50. 206/50=4.12 but again since you cannot buy 4.12 of a package you need to buy 5 packages for it to be enough.

2) B= 68, C=68
3) B=34, C= 34
4) B=34, C=68
The measurements of the angles ∠ABD and ∠ACD will be 34° and 34°. Then the correct option is C.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
Then the arc AD is double of angle ∠ABD.
∠ABD = arc AD / 2
∠ABD = 68° / 2
∠ABD = 34°
Similarly, the arc AD is double of angle ∠ACD.
∠ACD = arc AD / 2
∠ACD = 68° / 2
∠ACD = 34°
Thus, the measurements of the angles ∠ABD and ∠ACD will be 34° and 34°.
Then the correct option is C.

Well, p(y-k) = (x-h)2 has Vertex (h,k) = (3,5). So the Distance from vertex to directrix is 2; distance from vertex to focus is 2; focus is directly beneath the vertex. Therefore it's p = -2 ( I hope this helped<3)
How many angles are alternate interior angles with angle 9?
Brainliest for whoever answers first!!!!!!
Answer:
Angle 7 and angle 15
Step-by-step explanation:
Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.Alternate interior angles with angle 9 are:
Transversal s, parallel lines are t and u,
Angle 9 is in pair with angle 7Transversal u, parallel lines are s and r,
Angle 9 is in pair with angle 15If angle 9 is an interior angle within a pair of parallel lines cut by a transversal, then there would be one alternate interior angle to angle 9. The alternate interior angles are those inside the lines and on opposite sides of the transversal.
Explanation:In a pair of parallel lines cut by a transversal, the alternate interior angles are those angles that are inside the pair of lines and on opposite sides of the transversal. The alternate interior angles are equal when the lines are parallel. From your question, it's not clear which lines are parallel and where angle 9 is located.
Let's assume that angle 9 is one of the interior angles created by the transversal on a pair of parallel lines. In that case, there would be one angle that is an alternate interior angle to angle 9. So without more information, we can only say that there is one alternate interior angle to angle 9.

Landon left a garbage can on the lawn and the grass underneath it died. The diameter of
the can is 54 centimeters. What is the area of the grass that died? Use 3.14 for pi.
Answer:
The area of the grass that died is 2,289.06 cm²
Step-by-step explanation:
In order to calculate the area of the grass that died, we need to calculate the area of the bottom of the trash can. Since it's a circular shape it's area is given by:
area = pi*r²
Where r = d/2, therefore:
r = 54/2 = 27 cm
Applying this data to the formula, we have:
area = pi*(27)² = 2,289.06 cm²
The area of the grass that died is 2,289.06 cm²

The width of a rectangle is 1 units less than the length. The area of the rectangle is 56
units. What is the width, in
Units
Answer:
Width = 7 units
Step-by-step explanation:
Length = x units
Width = (x -1) units
Area = 56 square units
length * width = 56
x * (x - 1) = 56
x*x - x*1 = 56
x² - x - 56 = 0
x² -8x + 7x - 7*8 = 0
x(x - 8) + 7(x - 8) = 0
(x - 8)(x + 7) = 0
Here, (x +7) is ignored because measurement will not in negative.
x - 8 = 0
x = 8
Length = 8 units
Width = 8-1 = 7 units

Ashley use 1/5 cup of winegar in her salad dressing recipe. How much
vinegar would Ashley use to make 2/3 of a recipe? *
Answer:
I think the answer is 2/15 but I'm not a hundred percent sure
Ashley would use [tex]\(\frac{2}{15}\)[/tex] cup of vinegar to make [tex]\(2/3\)[/tex] of her salad dressing recipe.
To find out how much vinegar Ashley would use to make 2/3 of her salad dressing recipe, we need to calculate the amount of vinegar used in the full recipe and then scale it down to 2/3 of that amount.
In the full recipe, Ashley uses 1/5 cup of vinegar. To make 2/3 of the recipe, we multiply the amount of vinegar needed for the full recipe by 2/3:
[tex]\[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1}{5} \text{ cup} \times \frac{2}{3} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1}{5} \times \frac{2}{3} \text{ cup} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1 \times 2}{5 \times 3} \text{ cup} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{2}{15} \text{ cup} \][/tex]
So, Ashley would use [tex]\(\frac{2}{15}\)[/tex] cup of vinegar to make 2/3 of her salad dressing recipe. Simplifying [tex]\(\frac{2}{15}\)[/tex] gives us [tex]\(\frac{2}{15} = \frac{2 \div 1}{15 \div 1} = \frac{2}{15}\)[/tex], which is already in its simplest form. Thus, the final answer remains [tex]\(\frac{2}{15}\)[/tex] cup of vinegar.

Answer:
C. by hiring a local agent or broker who is familiar with her needs
and
E. by registering on the website of a national insurance company
Step-by-step explanation:
Just got this right on Plato :)
To independently obtain additional insurance, Natasha has two main options: hiring a local insurance agent or broker for personalized service, or registering on the website of a national insurance company for convenience and direct-purchase options.
Explanation:Natasha can accomplish her goal of obtaining additional insurance coverage independently from her employer by following two main paths:
C. by hiring a local agent or broker who is familiar with her needs, orE. by registering on the website of a national insurance company.By consulting a local insurance agent or broker, she can receive personalized advice and find coverage that fits her specific situation.
On the other hand, registering on the website of a national insurance company allows her the convenience to compare different plans and sign up for insurance that she can directly purchase.
Doing either will help her cover personal assets and health beyond what her employer provides without affecting her existing employment-based insurance coverage. It's important for her to assess her individual needs, risk factors, and financial situation when choosing the best insurance plans for her lifestyle.

What is the vertex of the parabola in the graph?
(
,
)
Answer:
(-3, -4)
Step-by-step explanation:
The solid circles along the parabola are:
(-6, 5), (-5, 0), (-4, -3), (-3, -4), (-2, -3), (-1, 0), (0, 5).
Although on observation, the minimum point of y occurs at (-3, -4), we can also confirm through the function.
The x-intercept of the parabola are -5 and -1.
x=-5 or x=-1
x+5=0 or x+1=0
(x+5)(x+1)=0
[tex]x^2+5x+x+5=0\\x^2+6x+5=0[/tex]
The Vertex of the equation occurs at the axis of symmetry, [tex]x=-\dfrac{b}{2a}[/tex]
In [tex]f(x)=x^2+6x+5, a=1, b=6[/tex]
Axis of Symmetry, [tex]x=-\dfrac{6}{2}=-3[/tex]
[tex]f(-3)=(-3)^2+6(-3)+5=9-18+5=-4[/tex]
Therefore, we can confirm that the vertex is (-3,-4) as stated earlier.
Find an equation of the line passing through the point (5,4) and parallel to the line whose equation is 2x+y=3
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =5 and y_1 =4
m the slope m= -2 (same slope for the line : 2x+y=3 because this lines are parallel and you can write y=-2x+3
an equation for this line is : y-4 = -2(x-5)
Final answer:
The equation of the line parallel to 2x + y = 3 and passing through the point (5, 4) is y = -2x + 14.
Explanation:
To find the equation of a line that is parallel to the given line 2x + y = 3 and passes through the point (5, 4), we first need to put the given line into slope-intercept form (y = mx + b), where m represents the slope and b the y-intercept. For the equation 2x + y = 3, we solve for y to get y = -2x + 3, which shows that the slope (m) is -2. Since parallel lines have the same slope, our new line will also have a slope of -2.
Using the point-slope form (y - y1 = m(x - x1)), where (x1, y1) is the point (5, 4) and m is -2, we get y - 4 = -2(x - 5). Simplifying this, y - 4 = -2x + 10, which leads to y = -2x + 14 as the equation of the line passing through (5, 4) and parallel to 2x + y = 3.
