Answer:

y=-8

Step-by-step explanation:

Let's solve your equation step-by-step.

15y−4=12y−28

Step 1: Subtract 12y from both sides.

15y−4−12y=12y−28−12y

3y−4=−28

Step 2: Add 4 to both sides.

3y−4+4=−28+4

3y=−24

Step 3: Divide both sides by 3.

−24

y=−8

D) Calculate the area of a circle with a circumference of 31.4 in.

dsp73

Answer:

A ≈ 78.54

Step-by-step explanation:

Area of a circle is A=πr^2

Since you do not know r (radius) you take the formula for the circumference of a circle (C=2πr), plug in 31.4 for C, and solve for r

Now that you have the radius of 4.99746521, you round it up to 5 and solve the area formula with 5 in as r.

Given P(A) = 0.56, P(B) = 0.45 and P(B|A) = 0.7, find the value of

miskamm [114]

Answer:

P(A and B) = P(AnB)

Step-by-step explanation:

$P( \frac{A}{B} ) = \frac{P(AnB)}{P(B)} \\from \: bayes \: theorem \\ P(AnB) = P(B) \times P( \frac{A}{B}) \\ = 0.45 \times 0.7 \\ = 0.315$

Jerry's strips of dry meat joint sells of these two types of dry meat. he sells twice as many bags of dried beef as he does bags

igomit [66]

Assume Jerry sells x bags of dried turkey, and 2x bags of dried beef. He profits ($2)x on dried turkey, and ($1.5)(2x) on the dried beef. Therefore, his total profit is 2x + 3x = 5x. Since this is equivalent to $500, we can solve
5x = 500
x = 100
Therefore, Jerry must sell 100 bags of dried turkey and 200 bags of dried beef.

Which exponential equation is equivalent to this logarithmic equation log x5 + log x12 =7

trapecia [35]

Answer:

x⁷ = 60

Step-by-step explanation:

Given :-

log x⁵ + log x ¹² = 7 .

To Find :-

The expotential equation .

Solution :-

Given logarithmic equation is ,

⇒ log x⁵ + log x ¹² = 7

⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]

⇒log x ⁶⁰ = 7

In expotential form we can write it as ,

⇒ x⁷ = 60
