What is the radius of a sphere with a volume of 996 cm 3 , 996 cm 3 , to the nearest tenth of a centimeter?
Answer: [tex]6.2\ cm[/tex]
Step-by-step explanation:
Given
The volume of the sphere is [tex]V=996\ cm^3[/tex]
Volume of sphere is given by [tex]V=\dfrac{4}{3}\pi r^3[/tex]
Insert the values
[tex]\Rightarrow 996=\dfrac{4}{3}\times \dfrac{22}{7}r^3\\\\\Rightarrow r^3=\dfrac{996\times 21}{88}\\\\\Rightarrow r=6.2\ cm[/tex]
Thus, the radius of the sphere is [tex]6.2\ cm[/tex]

Help pls pls pls pls
Answer:
C
Step-by-step explanation:
Answer:
option c is correct
Step-by-step explanation:
y = 2x +5
5 = 2*0 +5
5 = 0 +5
5=5
y = 2x +5
9 = 2*2 + 5
=9 = 4 +5
9=9
y = 2x +5
13 = 2*4 +5
13 = 8 + 5
13 = 13
therefore option c is correct because it satisfies all the elements of x and y of the given function when we substitute the values.

Step-by-step explanation:
We need to find the side of the square garden.
Area of square garden = 484 sq.feet
side² = 484
[tex]side = \sqrt{484}\\\\side = \sqrt{2*2*11*11} \\\\side = 2 * 11 = 22 feet[/tex]
What is the value of x?
45°
m
(2x-5)
n
Answer:
x = 70
Step-by-step explanation:
The two angles are same side interior angles and same side interior angles add to 180
45+ (2x-5) = 180
Combine like terms
2x +40 = 180
Subtract 40 from each side
2x+40-40 =180-40
2x =140
Divide by 2
2x/2 = 140/2
x = 70
Answer:
x=70
Step-by-step explanation:
hope it helped! :)

Find the measure of the exterior angle.
The measure of the exterior angle of the triangle is
Answer:
X = 132
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle therefore
x = 46 + 86
x = 132
Answer:
The measures of exterior angle is 132° .
Step-by-step explanation:
We know that the sum of interior angle is equal to the sum of exterior angle of triangle.
interior angle = exterior angle86° + 46 ° = x
combine like terms
132° = x
8 friends go out for dinner and the bill for food and drink comes to £120. The friends decide to add a 20% tip on top of this total. If they divide the expense equally between them, how much does each friend pay?
Answer:
$18
Step-by-step explanation:
Given the following data;
Number of friends = 8
Total expense = $120
Tip = 20%
To find how much each friend would pay?
First of all, we would determine the amount of tip.
Tip = 20/100 * 120
Tip = 2400/100
Tip = $24
New balance = total expense + tip
New balance = 120 + 24
New balance = $144
Next, we find how much each friend would pay using the mathematical expression;
Each paid = 144/8
Each paid = $18

The cost of a computer processor is directly proportional to its speed.
A 4GHz processor costs £400.
Find the cost of a 6GHz processor
Answer:
Step-by-step explanation:
If cost is directly proportional to speed, then the equation for this is
£ = ks, where k is the constant of proportionality. We need to solve for this first.
400 = k4 so
100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:
£ = (100)(6) so
£ = 600
f (x) = (3x - 2). find f^-1f (10)
f-¹f(10)=10
Answer:
Solution given:
f(x)=3x-2
let
y=3x-2
interchanging role of x and y
x=3y-2
y=[tex]\frac{x+2}{3}[/tex]
so
f-¹(x)=[tex]\frac{x+2}{3}[/tex]
now
f(10)=3*10-2=28
now
f-¹f(10)=f-¹(28)=[tex]\frac{28+2}{3}[/tex]=10

Find the area if the composite shape
Answer:
111 m²
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides and four angle) with two pairs of parallel sides. Opposite sides of a rectangle are equal to each other. Also all the angles of a rectangle are 90° each.
The area of a rectangle = length * width
For rectangle 1, length = 12 m, width = 3 m
Therefore area of rectangle 1 = length * width = 12 m * 3 m = 36 m²
For rectangle 2, length =(12 m - 3 m - 3 m) = 6 m, width =(15 m - 10 m) =5 m
Therefore area of rectangle 2 = length * width = 6 m * 5 m = 30 m²
For rectangle 3, length = 15 m, width = 3 m
Therefore area of rectangle 3 = length * width = 15 m * 3 m = 45 m²
Area of composite shape = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Area of composite shape = 36 m² + 30 m² + 45 m² = 111 m²

linear equation

Answer:
below
Step-by-step explanation:
you can find the distance between the y values for each x value and if it comes out to be an even increase/decrease you know it is linear
Answer:
It does not form a linear equation.
Step-by-step explanation:
For this question, you should check that they all have the same gradient.
To work out the gradient, use [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].
Using the top 2 rows, this gives [tex]\frac{-1--3}{-2--6}[/tex], or [tex]\frac{2}{4}[/tex], simplified to [tex]\frac{1}{2}[/tex]. This means for every increase in x by 1, y increases by [tex]\frac{1}{2}[/tex].
Between the first 2 rows, x increases by 4 and y by 2 (half of 4), so it is true.
Between the second and third rows, x increases by 2 and y by 2 (which isn't half of 2). This is false, meaning this does not form a linear equation.
**This question involves solving linear equations using gradients, which you may want to revise. I'm always happy to help!
The projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s2. A rocket is launched from the ground at an initial velocity of 39.2 meters per second. Which equation can be used to model the height of the rocket after t seconds? s(t) = –4.9t2 + 39.2 s(t) = –4.9t2 + 39.2t s(t) = –4.9t2 + 39.2t + 39.2 s(t) = –4.9t2 + 39.2t – 39.2
Answer:
s(t) = -4.9t² + 39.2t
Step-by-step explanation:
Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²
Given
g = -4.9m/s²
v0 = 39.2m/s
s0 = 0m (the initial height)
On substituting into the formula;
s(t) = gt² + v0t + s0
s(t) = -4.9t² + 39.2t + 0
s(t) = -4.9t² + 39.2t
This gives the equation that models the height

What is the equation of a circle with center (2, -5) and
radius 4?
Answer:
(x-2)^2 +(y+5)^2=4^2
Step-by-step explanation:
x minus 2 squared + y plus 5 squared = radius squared
Answer:
(x-2) ^2 + ( y+5)^2 = 16
Step-by-step explanation:
The equation for a circle is given by
(x-h) ^2 + ( y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-2) ^2 + ( y- -5)^2 = 4^2
(x-2) ^2 + ( y+5)^2 = 16
x + 2/3 = 8/9 x=__ ..........................................
Answer:
x = -6
Step-by-step explanation:
[tex]x+\frac{2}{3}=\frac{8}{9}x\\\\x = \frac{8}{9}x - \frac{2}{3}\\\\x - \frac{8}{9}x= -\frac{2}{3}\\\\\frac{9}{9}x-\frac{8}{9}x=\frac{2}{3}\\\\\frac{1}{9}x=-\frac{2}{3}\\\\x=-\frac{2}{3}*\frac{9}{1}\\\\x=(-2)*3\\\\x = -6[/tex]
Answer:
x = [tex]\frac{2}{9}[/tex]
Step-by-step explanation:
Given
x + [tex]\frac{2}{3}[/tex] = [tex]\frac{8}{9}[/tex] ( multiply through by 9 to clear the fractions )
9x + 6 = 8 ( subtract 6 from both sides )
9x = 2 ( divide both sides by 9 )
x = [tex]\frac{2}{9}[/tex]
What is the remainder when x^3-8x^2+20x-16 is divided by x+2?
Answer:
(x - 4)(x - 2)²
Step-by-step explanation:
x³ - 8x² + 20x - 16
x³ - 4x² + 4x - 4x² + 16x - 16
x(x² - 4x + 4) - 4(x² - 4x + 4)
(x - 4)(x² - 4x + 4)
(x - 4)(x² - 2x - 2x + 4)
(x - 4)(x(x - 2) - 2(x - 2))
