Answer:
r = 1.68 ft
Step-by-step explanation:
Volume of a sphere, V = 4/3πr³
V = 20 ft³
π = 3.14
r = ?
V = 4/3πr³
20 = 4/3 × 3.14 × r³
20 = (4×3.14×r³)/3
Cross product
20 × 3 = 4 × 3.14 × r³
60 = 12.56r³
r³ = 60/12.56
= 4.7771
r = 3√4.7771
= 1.6842
Approximately
r = 1.68 ft to the nearest hundredth

Answer:
The value of x is 84 and the remaining angles are: 76° and 86°
Step-by-step explanation:
Given three angles are
18
x-8
and
x+2
We have to find the angles and for that we have to find the value of x
As we know that the sum of internal angles of a triangle is 180°
So,
[tex]18+(x-8)+(x+2) = 180\\18+x-8+x+2 = 180\\2x+12 = 180\\2x = 180-12\\2x = 168\\x = \frac{168}{2}\\x = 84[/tex]
And the angles are:
x-8 = 84-8 = 76
x+2 = 84+2 = 86
Hence,
The value of x is 84 and the remaining angles are: 76° and 86°

Solve for x
Answer:
x = 5
Step-by-step explanation:
We are to solve for x
7 - 10/x = 2 + 15/x
We Multiply both sides by x
x(7 - 10/x) = x(2 + 15/x)
7x - 10 = 2x + 15
Collect like terms
7x - 2x = 15 + 10
5x = 25
x = 25/5
x = 5

Answer:
(c) 11
Step-by-step explanation:
As x goes up by 1, f(x) goes up by 2. The next line of the chart would be ...
x = 4+1 = 5; f(x) = 9+2 = 11
The appropriate choice is f(5) = 11.

Answer:
y=-4x+5
Step-by-step explanation:
Let us first find the slope.
Given the points, (0,5) and (1,1) The slope of the line is (5-1)/(0-1)=
4/-1=
-4
The line also intercects the y axis at (0,5) Therefore, the b intercept would be 5
The final equation would be,
y=-4x+5
I hope this helps! :)
Answer:
y = -4x + 5
hope this helps !! have a fantastic day :))

Answer:
The intersection point is (-0.5, -1).
So the x-coordinate is -0.5.
Step-by-step explanation:
Using the elimination method:
2.4x - 1.5y = 0.3
1.6x + 0.5y = -1.3 Multiply this equation by 3:
4.8x + 1.5y = -3.9 Add this equation to the first one:
7.2x = -3.6 - note we eliminate the terms in y.
x = -3.6 / 7.2
x = -0.5.
Now plug this into the first equation:
2.4(-0.5) - 1.5y = 0.3
-1.5y = 0.3 + 2.4*0.5
-1.5y = 1.5
y = -1.
-3x+6y=15 and -3x-2y=-1*

Which number line represents the solution to 5x ≥ 30?
Answer:
Its B
Step-by-step explanation:
since the symbol has a line underneath its shaded so A & B are left.
the symbol shows > so the point is where the line goes, for this question it goes to the right.
The required number line represents the solution to 5x ≥ 30 is shown in option B.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
According to the question, the inequality 5x ≥ 30 can be solved by dividing both sides by 5, which gives x ≥ 6. This means that any number greater than or equal to 6 is a solution to the inequality.
Looking at the number line options, we can see that only the last one correctly represents the solution to the inequality. The line starts at 6 and includes all numbers greater than or equal to 6, which matches the solution x ≥ 6.
Therefore, the correct answer is the number line shown in option B.

Answer and Step-by-step explanation:
First, look at the inequality. We see the there is a greater than or equal to sign.
That means the graphs can NOT be C or D, since those graphs only apply to inequalities with the greater than or less than sign.
That leaves us with graphs A and B.
We see the y is greater than the value, so anything above the line is filled in.
That means that graph A is the answer. Which means,
Answer choice B, graph A.

if the base area of a cylinder is 15.6 square centimeters and the height is four centimeters what is the volume of the cylinder?
Answer:
Volume of the cylinder = 62.4 cm³
Step-by-step explanation:
Volume of a cylinder = area of base × height of the cylinder
Area of base = 15.6 square centimeters
Height of the cylinder = 4 centimeters
Volume of a cylinder = area of base × height of the cylinder
= 15.6 cm² × 4 cm
= 62.4 cm³
Volume of the cylinder = 62.4 cm³
