Answer:

V≈ 111.43 in³

Step-by-step explanation:

Equation- V = πr² × h/3

1) Divide the diameter in half to make the radius, which equals 2.85 as r.

2) Plug in the radius(r) and height(h) with the correct numbers.

3) Simply solve

V = π(2.85)² × 13.1 ÷ 3

V= 25.52 × 13.1 ÷ 3

V= 334.312 ÷ 3

V= 111.4373+

V≈ 111.43

Antonio orders an iPhone case off of Amazon for $27. He has to pay an additional 3% for shipping and handling. How much will his

Wewaii [24]

Answer:

We conclude that total cost/bill will be: $27.81

Step-by-step explanation:

Given

The cost of an iPhone case = $27

Additional expense = 3% = 3/100 = 0.03

To determine

Total bill = ?

The expense amount can be calculated by multiplying the cost of an iPhone case by the additional expense

i.e.

Expense Amount = cost of an iPhone case × additional expense

= 27 × 0.03

= $0.81

The total cost is calculated by adding the expense amount and the original cost of an iPhone case.

i.e.

Total cost/bill = Expense Amount + cost of an iPhone case

= $0.81 + $27

= $27.81

Therefore, we conclude that total cost/bill will be: $27.81

What are two numbers multiplied together to get 15 but add to be 12?

KiRa [710]

So x times y=15
x+y=12
solve
x+y=12
subtract x from both sides
y=12-x
subsitute
xy=15
x(12-x)=15
distribute
12x-x^2=15
subtract (12x-x^2) from both sides
0=x^2-12x+15
use quadratic formula which is
x= $\frac{ -b+/- \sqrt{b^{2}-4ac} }{2a}$
where you have
0=ax^2+bx+c
so
a=1
b=-12
c=15
subsitute
x= $\frac{ -(-12)+/- \sqrt{-12^{2}-4(1)(15)} }{2(1)}$
x= $\frac{ 12+/- \sqrt{144-60} }{2}$
x= $\frac{ 12+/- \sqrt{84} }{2}$
x= $\frac{ 12+/- 2\sqrt{21} }{2}$
x=6+/- $\sqrt{21}$
x=6+ $\sqrt{21}$ or 6- $\sqrt{21}$ or aprox
x=10.5826 or 1.41742
the numbers are 10.5826 and 1.41742

Identify an equation in point-slope form for the line parallel to y = -

inessss [21]

It wouldn’t be any of those- because its in point-slope form ( y-y1=m(x-x1) ) the slope is -2/3, then the -5 (y) turns to +5 because there’s 2 negatives- since the x is positive it stays subtraction

The Correct equation would be y+5=-2/3(x-4)

Hope that helps :)
