868.34 cubic yards (yd³) of mulch is needed to cover 2 ft in from the edge to a depth of 3.5 inches,
To calculate square feet for a circular area, measure the distance from the center of the bed to the outer edge (this is the radius R) .Then area is given by square meters of circular area = [tex]R\times R\times\ 3.14[/tex] ....(1)To determine the amount of mulch you need 1. Multiply the square feet of your bed by the number of inches of mulch you want to deep . 2. Divide this number by 324 . You will get the amount of mulch you need in a cubic yard.It is given that a circular flower bed, 320 ft in diameter which means radius[tex]=\frac{320}{2}= 160 \ ft[/tex]
Putting r = 160 in equation (1) , we get
[tex]A=160\times160\times3.14\\A=80384 \ ft \ sqaure \ units[/tex]
We need the mulch 3.5 inches deep
[tex]80384\times3.5=281344[/tex]
On dividing the above number by 324 , we will get the required cubic yards [tex]\frac{281344}{324} =868.34[/tex]

Step-by-step explanation:
by what factor would you need to change the radius of a sphere, such that its volume increased by a factor of 7? give your answer to two digits.
The factor by which radius of the sphere be changed is 1.91, which is calculated hy applying the concepts of surface area and volume on the assigned problem.
What do you mean by volume?
Volume is defined as the 3D measurement that deals with the amount of space required by an object. It is always calculated in cubic units. Its basic unit is cubic metre.
Calculation of the change in radius of sphere when its volume is increased by 7
Let the radius and volume of sphere be r and v respectively
Volume of sphere, v = 3.16 × ( r )3 —- 1
Now, changed radius, R = xr
Where x is the factor, we need to calculate
Changed volume, V = 7v = 3.16 × ( R )3 -— 2
From equations 1 and 2, we get,
7v / v = ( R )3 / ( r )3
7 = ( xr )3 / ( r )3
7 = (x)3 × 1
Taking cube root both sides,
x = 1.913
Hence, the factor by which radius of the sphere be changed is 1.91.

True statements that prove the lines a and b are parallel.So according the question
We have
Angle between line a and c = m∠1Angle between line a and d = m∠1Angle between line b and c = (4x-10)°Angle between line b and d = 58°Angle between line c and d = (3x-1)There are two angles from the c and d lines with the lines a and b being equal that can be used to determine whether the lines a and b are parallel.
That's mean
Angle between line a and c = Angle between line b and cm∠1 = (4x-10)°
Angle between line a and d = Angle between line b and dm∠2 = (58)°

Ascending order is 1/6< -4/-9< 11/12 < -21/ -18.
Here the fraction is -4/-9, 11/12, -21/-18, 1/6.
To know write the fraction in its ascending form, and convert the fraction into it's decimal form.
Therefore we have,
-4/-9 = 4/9 = 0.44
11/12 = 0.916
-21/-18 = 21/18 = 7/ 6 = 1.16
1/6 = 0.16
Therefore ascending order is 0.16< 0.44< 0.916 < 1.16. That is 1/6< -4/-9<11/12 < -21/-18.

Each phone costs $19 per month.
Taxes are $9.50 per month.
What is the cost for their current plan?
The cost for their current plan is $83.5
How to write and solve the cost for their current plan?The given parameters are
Price for 30 gigabytes of data and unlimited talk and text = $55.
Phone costs = $19 per month.
Taxes = $9.50 per month.
The equation of the cost for their current plan is represented as:
Total cost = Price for 30 gigabytes of data and unlimited talk and text + Phone costs + Taxes
So, we have
Total cost = 55 + 19 + 9.50
Evaluate the sum
Total cost = 83.5
Hence, the cost for their current plan is $83.5

-2 = 2 + v/4
The simplification of the equation - 2 = 2 + v/4 is v = - 16.
Equation, which is defined as the quality of being equal, is frequently represented by a mathematical expression with equal values on either side or by a situation in which numerous factors must be taken into account.
Consider the equation,
-2 = 2 + v/4
The equation can be rewritten as:
-2 = 2/1 + v/4
The least common multiple or LCM of 1 and 4 is 4.
-2 = ( 2 × 4) / (1 × 4) + v /4
-2 = 8/4 + v/4
-2 = ( 8 + v) /4
Multiplying each side of the equation by 4
- 2 × 4 = [ ( 8 + v ) / 4 ] × 4
- 8 = 8 + v
Subtracting each side of the equation by 8.
- 8 - 8 = 8 + v - 8
v = - 16

The weight of the egg is 15.79 grams.
Normal Distribution:
Normal distribution, refers the probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Given,
The normal model n(58,21) describes the distribution of weights of chicken eggs in grams.
suppose that the weight of a randomly selected chicken egg has a z-score of -2.01.
Here we need to find the weight of the egg and we have to round off it to the nearest hundredth of gram.
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
So,
X ~ n(58, 21)
Where this means the value of
σ = 21
[tex]\mu[/tex] = 58
Apply the values on the formula,
[tex]Z=\frac{x-\mu}{\sigma}[/tex]
=> -2.01 = (x - 58) / 21
=> -2.01 x 21 = x - 58
=> -42.21 + 58 = x
=> x = 15.79
So, the weight of the egg is 15.79 grams.
When we round off it to the nearest hundredth then we get,
=> 15.79

A gallon of gasoline costs $2.96.Gas tank capacity of the given car = 25 gallonThat car can travelled 28.8 miles on each gallon of gasoline.To find
The cost of filling your gas tank if it is already 38 % full.How much money spend on gasoline on the trip of 705 miles.So according the question
We have
1 gallon of gasoline = $2.96.Gas tank capacity = 25 gallon.28.8 miles travelled on each gallon of gasoline.Now, for finding
a.) The cost of filling your gas tank if it is already 38 % full.
38 % of 25 gallon = 9.5 gallon
the unfilled part of the tank = 25-9.5 = 15.5 gallon
So the tank can filled 15.5 gallon of gasoline more now.
The cost of 15.5 gallon of gasoline
= 15.5 × cost of 1 gallon of gasoline
= 15.5 × 2.96
= $45.88
$48.88 required to fill the gas tank if it is already 38% full.b.) How much money spend on gasoline on the trip of 705 miles.
∵ Car can travelled in 1 gallon of gasoline = 28.8 miles.
∴ Gasoline required to travel 705 miles = [tex]\frac{705}{28.8}[/tex]
= 24.48 gallon.
The cost of 24.48 gallon of gasoline
