Can someone pls help me with this question ​

Mathematics
1 answer:
jeyben [28]2 years ago
7 0

Answer:

I'll find X for you; the next step is by you.

Step-by-step explanation:

we have two similar pentagons

I will do it in 2 ways.

1.

=> 48/4x = (x+2)/x

=> 12/x = (x+2)/x

Because of pentagons so x > 0

=> 12 = x + 2 => x = 10

2.

k is unknown number

=> 4x = k.x and 48 = k.(x + 2) (x > 0)

=> k = 4 and 48 = 4.(x + 2)

=> 12 = x + 2 => x = 10

Weinstein, McDermott, and Roediger (2010) con- ducted an experiment to evaluate the effectiveness of different study strategies.
anastassius [24]

Answer:

a) The number of correct answers

b) Discrete

c) Ratio        

Step-by-step explanation:

We are given the following in the question:

Experiment:

Evaluate the effectiveness of different study strategies. All students were then given a test on the passage material and the researchers recorded the number of correct answers.

a) The dependent Variable

The number of correct answers given is the dependent variable because it depends on the number of times the passage is read.

b) Nature of dependent variable.

  • It is a discrete variable.
  • Since, the number of questions will always be expressed in whole numbers and cannot be expressed as decimals.
  • They are always counted and not measured.

c) Scale of measurement

  • Ratio is used to measure the dependent variable because true zero for the number of correct questions answered exist.
  • If the measure is zero that means truly no questions were answered correctly.

Brian invests £4000 into his bank account.
GuDViN [60]

Answer:

10.24 years

Step-by-step explanation:

The computation of the time period is as follows:

As we know that

Amount = Principal × (1 + rate of interest)^time period

£8000 = £4000 × (1 + 0.07)^time period

£8,000 ÷ £4,000 = 1.07^time period

2 = 1.07^time period

Now apply the log to the both sides

log 2 ÷ log 1.07 = time period

= 10.24 years

How do you write 5y<3 without exponents?
satela [25.4K]

Answer:

When an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously mentioned exponent laws.
