Answer:
r = 6
Step-by-step explanation:
The value of radius of the sphere rounded to the nearest whole number is,
⇒ r = 6 cm
We have to given that,
Volume of a sphere = 905 cm
Since, We know that,
Volume of sphere = 4/3 (πr³)
Where, 'r' is radius of sphere.
Now, Substitute the given value, we get;
⇒ 905 = 4/3 (πr³)
⇒ 905 × 3 = 4 × 3.14 × r³
⇒ 2,715 = 12.56 × r³
⇒ r³ = 216.16
⇒ r = ∛216.16
⇒ r = 6 cm
Thus, The value of radius of the sphere rounded to the nearest whole number is,
⇒ r = 6 cm

if john weighs 8lbs less than twice his sister's weight, what is the difference between their weight if john weighs 180 lbs?
Answer:
86 is the difference
Step-by-step explanation:
180 + 8 = 188
188 / 2 = 94
188 - 94 = 86
Answer:
The difference between their two weights is 86 lbs
x•2-8=180 (x= sister weight)
180+8=188
188÷2= 94 (x=94)
189-94= 86

[46664792)
Answer:
31°
Step-by-step explanation:
The angle 59° will be equal to the angle c in triangle ABC.
Angle B will be 90°
Angle A + Angle B + Angle C = 180° (ASP)
Angle A + 90° + 59 ° = 180 °
Angle A = 180° - 90° - 59°
Angle A = 31°
Angle A = x
31° = x

Dawn is ordering 1 veggie sandwich for every 3 ham sandwiches. She needs 12 sandwiches in all. Veggie sandwiches cost 4.00 dollars each and ham sandwiches cost 4.50 each. How many will dawn spend on sandwiches?
Answer:
$52.50
Step-by-step explanation:
Lets use V for Veggie, and H for Ham.
V=4
H=4.50
She is getting 12 sandwiches, and Every 3 H, she buys one V.
So, the order of her buying the sandwiches would be:
H H H V H H H V H H H V
9 H and 3 V
9*H=40.5
3*V=12
40.5+12= $52.50
The total cost of all the sandwiches is given by the equation A = $ 52.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total cost of 12 sandwiches be A
Now , the equation will be
For every 1 veggie sandwich 3 ham sandwiches are ordered by Dawn
The cost of veggie sandwich = $ 4.00
The cost of ham sandwich = $ 4.50
So ,
Let the veggie sandwich be = x
Let the ham sandwich be = y
The total number of sandwiches = 12
So , x + 3y = 12
when x = 3 and y = 3
3 + 3 ( 3 ) = 12
3 + 9 = 12
12 = 12
Therefore , the number of veggie sandwich = 3
The number of ham sandwich = 9
And , the cost of 3 veggie sandwich = 3 x 4.00
The cost of 3 veggie sandwich = $ 12
The cost of 9 ham sandwich is = 9 x $ 4.50
The cost of 9 ham sandwich is = $ 40.5
The total cost of 12 sandwich A = cost of 3 veggie sandwich + cost of 9 ham sandwich
Substituting the values in the equation , we get
The total cost of 12 sandwich A = 12 + 40.50
The total cost of 12 sandwich A = $ 52.50
Therefore , the value of A is $ 52.50

5/2 ÷ 3/4
pls help me solve this
Answer:
3 1/3 Because When we divide two fractions, such as 5/2 ÷ 3/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
Step-by-step explanation:
remember to simplify if ever possible!:D
soooo
in order to do this both fractions has to have the same denominator
so you find the CMD (common denominator)
which is 4
so you'd only change 5/2
5/2 * 2/2 to make it 10/4
now both fractions have the same denominator
you do keep change flip
you keep 10/4
change division to multiplication
and flip 3/4 TO 4/3
which would equal
10/4 * 4/3= 40/12
40/12
and you divide it with long division
you get 3 as ur quotient
divisor as 12
and remainder as 4
= 3 4/12
nd u simplify which u divide 4/12 by 4 and get 1/3
so the answer would be 3 1/3
and in order to check you can use an online fraction calculator

Line q goes through points (-3, 3) and (-5, -3). At what point does line q cross the y-axis?
Answer:
(0, 12 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (- 5, - 3)
m = [tex]\frac{-3-3}{-5+3}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = - 9 + c ⇒ c = 3 + 9 = 12 ← y- intercept
Thus the line crosses the y- axis at (0, 12 )
Answer:
It crosses the y-axis at the point where y = 12
- the point (0, 12).
Step-by-step explanation:
First we need to find the equation of the line q:
The slope of the line = (-3-3)/(-5-(-3))
= -6/-2
= 3.
Using the point-slope form of a line:
y - y1 = m(x - x1) Take the point (-3, 3):
y - 3 = 3(x -(-3)
y - 3 = 3x + 9
y = 3x + 12.
Where q crosses the y-axis x = 0 so we have
y = 3(0) + 12
y = 12
The required point is (0, 12).

Factor X^2-13x+22 help pls
Answer:
(x-2)(x-11)
Step-by-step explanation:
Answer:
(x - 2)(x - 11)
Step-by-step explanation:
We have a polynomial and are asked to factor it.
Polynomial : x^2 - 13x + 22
Usually a trick I follow when factoring is that for c (in this case 22). You need to find two numbers that will multiply to it. And for b (in this case -13) you will need to find two numbers that will add to it, the same numbers you multipled for c.
So
x * y = 22
x + y = -13
These two numbers are -11 and -2.
