A bucket holds b liters of water. But a jar holds 8 fewer liters than the bucket. How many times can the bucket hold than the ja

kykrilka [37]

Answer:

b / (b - 8)

Step-by-step explanation:

Given that :

Litres of water held by bucket = b

Jar holds 8 litres fewer than bucket; hence, litres held by jar = b - 8

The number of times bucket can hold than jar is :

Litres held by bucket / litres held by jar

b / (b - 8)

Determine if the following equations are equal by evaluating both sides

padilas [110]

Answer:

Yes, the both sides of the given equation are equal.

Step-by-step explanation:

The given equation is

$\log((1-i)^3)=3\log(1-i)$

Taking LHS,

$LHS=\log((1-i)^3)$

Using the power property of logarithm, we get

$LHS=3\log(1-i)$ $[\because log_ax^n=nlog_ax]$

$LHS=RHS$ $[\because RHS=3\log(1-i)]$

Both sides of the given equation are equal.

If SAT scores are normally distributed with a mean of 1518 and a standard deviation of 325, find the probability that a randomly

aliya0001 [1]

Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575

Z = (X - x_bar)/sigma

Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18

From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714

P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316

The correct answer is C.

12/35 = 36/X find x step by step

Zigmanuir [339]

Answer:

x = 105°

Step-by-step explanation:

Question :

$\frac{12}{35} =\frac{36}{x}$

You can use cross multiplication to solve this.

Let us solve now

$\frac{12}{35} =\frac{36}{x}$

12 × x = 35 × 36

12x = 1260

Divide both sides by 12.

x = 105°

Hope this helps you :-)
