Answer:

175%

Step-by-step explanation:

1. To find how much a percent of a number is, we'd just have to multiply the percent by the number. However, in this case, we're missing the percentage.

2. To find that percentage, we can write an equation of \frac{x}{100} * 4 = 7 because "of 4" means to multiply by 4, and "is 7" means that the product is 7.

3. Now, let's solve our equation.

  • \frac{x}{100} * 4 = 7

Step 1: Simplify both sides of the equation.

  • \frac{4}{100}x = 7
  • \frac{1}{25}x=7

Step 2: Multiply both sides by 25.

  • \frac{1}{25}x * 25 = 7 * 25
  • x = 175

Step 3: Check to see if solution is correct.

  • \frac{175}{100} * 4 = 7
  • \frac{700}{100} = 7
  • 7 = 7

Therefore, the answer is 175%.

Blake is a member of a golf club. When he became a member, he deposited money into his club account. For each round of golf that
Leno4ka [110]

Answer:

D)  Blake's account initially had $320, which is decreasing at the rate of $20 per round.

Step-by-step explanation:

Here, according to the question:

x: The total number of golf rounds played

y: Represents the amount, in dollars, left in his account after playing x rounds

Let as assume A is the amount deposited initially.

y = A  - n x    here n : rate of each round played

Also, here

if x  = 2, then y = 280

if x  =4, then y = 240

If x  = 2 and y = 280, then:

y = A  - n x ⇒  280 = A  - 2 n   ... (1)

If x  = 4 and y = 240, then:

y = A  - n x ⇒  240 = A  - 4 n   ... (2)

Solving (1) and (2)  by (1) - (2),  we get:

40 = 2 n or, n  = 20

Putting n = 20 in 280 = A  - 2 n, we get: A  = 280 +  2(20) = 320

⇒ A = $320, n = $20

⇒ The amount initially deposited is $320 and the rate per round is  $20

Hence ,Blake's account initially had $320, which is decreasing at the rate of $20 per round.

By taking  = 3.141 and
Whitepunk [10]

The value of the expression 1/√2 + π where the given parameters are π = 3.141 and  √2 = 1.414 is 3.848

<h3>How to evaluate the expression?</h3>

The given parameters are

π = 3.141

√2 = 1.414

The expression to evaluate is given as:

1/√2 + π

Start by substituting π = 3.141 and √2 = 1.414 in the expressions 1/√2 + π

1/√2 + π = 1/1.414 + 3.141

Evaluate the quotient

1/√2 + π = 0.707 + 3.141

Evaluate the sum

1/√2 + π = 3.848

Hence, the value of the expression 1/√2 + π where the given parameters are π = 3.141 and  √2 = 1.414 is 3.848
