There are a few ways to find out the correct answer. One of them is to divide 2.40 by 6 to get a price of one cake and then multiply it by 10:

2.40 ÷ 6 = 0.40
0.40 * 10 = 4.00

Answer: Ten cakes would cost 4 pounds.

Joseph and Isabelle left Omyra’s house at the same time. Joseph jogged north at 8 kilometers per hour, while Isabelle rode her b

Artist 52 [7]

For this case the distance will be given by:
d ^ 2 = (12 * 1.5) ^ 2 + (8 * 1.5) ^ 2
Rewriting we have:
d ^ 2 = (18) ^ 2 + (12) ^ 2
d ^ 2 = 324 + 144
d ^ 2 = 468
d = root (468)
d = 21.63 Km
Answer:
1) She did not find the full distance each traveled in 1.5 hours.
2) She should have used 12 km for Joseph's distance and 18 km for Isabelle's distance.

What is the value of this expression?

mylen [45]

9514 1404 393

Answer:

Step-by-step explanation:

I find it convenient to remember that a logarithm is an exponent.

$\log_a(a^b)=b$

log₂(8) +log₃(1/3) = log₂(2³) +log₃(3⁻¹)

= 3 -1 = 2

The value of the expression is 2.

Some calculators can compute this for you directly.

A paint company has a specific type of interior paint which costs $5.55 to produce each unit. The company also has a fixed cost

Maurinko [17]

Answer:

Minimum total cost = $20550

maximum revenue $44,100

Step-by-step explanation:

Given data:

Production cost $5.55 per unit

Fixed cost = $15000 per month

Price, p = 42-0.01 q

where. q represent number of unit produced

revenue can be wriiten as

p.q = 42q - 0.01q^2

1) from information 1000 unit has to produced therefore

total cost = 15000 + 5.55×1000 = $20550

Minimum total cost = $20550

2) Revenue = 42q - 0.01q^2

$\frac{d revenue}{dq} = 42q - 2\times 0.01q = 0$

therefore for maximum revenue q is = 2100

so, maximum revenue $= 4.2 \times 2100 - 0.01(2100)^2$

= $44,100
