Answer:

243 m²

Step-by-step explanation:

Given the scale is 4 : 6 = 2 : 3 , then

scale of areas = 2² : 3² = 4 : 9

area of scale drawing = 12 × 9 = 108 cm²

let x be the actual area then using proportion

$\frac{4}{108}$ = $\frac{9}{x}$ ( cross- multiply )

4x = 972 ( divide both sides by 4 )

x = 243

Actual area = 243 m²

It costs $50.00 to deliver 6 floral arrangements. It costs $80.00 to deliver 12 floral arrangements. What is the constant rate o

german

The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00

Equation: f(z)=20+5z

Step-by-step explanation:

Given,

Delivery cost of 6 floral arrangements = $50.00

Delivery cost of 12 floral arrangements = $80.00

Let,

x be the constant rate for each floral arrangement.

y be the initial value.

According to given statement;

6x+y=50.00 Eqn 1

12x+y=80.00 Eqn 2

Subtracting Eqn 2 from Eqn 1

$(12x+y)-(6x+y)=80.00-50.00\\12x+y-6x-y=30.00\\6x=30.00$

Dividing both sides by 6

$\frac{6x}{6}=\frac{30.00}{6}\\x=5.00$

Putting in Eqn 1;

$6(5.00)+y=50.00\\30.00+y=50.00\\y=50.00-30.00\\y=20.00$

The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00

Equation for the function;

Let z be the number of floral arrangements.

f(z) = initial fee + 5*Number of floral arrangements

f(z) = 20+5z

Clara opened a bank account. She deposited $95 each month for 10 months. Her bank charged her 2$ each month to use the account.

The answer is C.. because if you do 95x100 you get 950 and then you need to do 2x10 and you get 20, so then you subtract 20 from 950 and you will get $930

Answer:

Basically find the unit rate by doing 3.99/24 = $0.16625/1oz

1 quart = 32 ounces so 4.8/32 = $0.15/1oz

1 gallon = 153.722 ounces so 11/153.722 = 0.07

49.6/768.61 = 0.06
