Find the cost of 20 grams of lead at 60$ per kilogram
ASHA 777 [7]

Answer:

$1.20

Step-by-step explanation:

Ratio:

Grams : Kilograms

1 : .001

Multiply both sides by 20 to convert grams to kilograms:

Grams : Kilograms

1 : .001

x20 x20

20 : .02

This means that 20 grams of lead = .02 kilograms of lead

Price:

Cost : Kilogram

$60 : 1

Multiply both sides by .02 to find the price of the lead:

Cost : Kilogram

$60 : 1

x.02  x.02

$1.20 : .02

Therefore, .02 kg of lead costs $1.20.

Solve the following equation. log Subscript 2 Baseline (3 x plus 7 )equals 5 The solution set is StartSet nothing EndSet . ​(Sim
tigry1 [53]

Answer: x=\dfrac{25}{3}

Step-by-step explanation:

The given equation : \log_2(3x+7)=5

Using logarithmic property : \log_a N=M\to N=a^M

The given equation will be equivalent to (3x+7)=2^5

\Rightarrow\ 3x+7=32

Subtract 7 from both sides , we get

3x=25

Divide both sides by 3 , we get

x=\dfrac{25}{3}

Hence, the solution is x=\dfrac{25}{3}
