Answer:
the answer for question 1 is -7
Make a proportion
6/18 = 10/z
Cross multiply
180 = 6z
180/6 = z
Z = 30
Answer:
2 is the answer
Step-by-step explanation:
its like
(square root 2)^2
{square root and whole square is cancelled and 2 is the answer}
Answer:
Volume = 35185.8 
Step-by-step explanation:
Recall the formula for the volume of a cone: 
Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)
And h stands for the height of the cone (in your case 21 km)
We replace such in the formula and calculate its final value:

We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:
Volume = 35185.8 
The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775
($4,100 × 0.0775 + $4,100 ) + $600
Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).
P = Parenthesis
E = Exponent
M = Multiplication
D = Division
A = Addition
S = Subrtaction
$4,100 × 0.0775 + $4,100 ) + $600
$4,417. 75 + $4,100 + $600
$4,417. 75 + $600 = $5,017.75
Danielle made $5,017. 17 last week.
I hope this helps! :)
