Answer:

P = 28cm

Step-by-step explanation:

The general formula for the perimeter of a rectangle is: 'P = 2L +2W' (L being the length and W being the width of the rectangle.)

Step 1: Substitute L = 7, W = 7 into the general formula.

P = 2(7) + 2(7)

Step 2: Solve!

P = 2 x 7 + 2 x 7

P = 14 + 14

P = 28

Step 3: Don't forget to add the units of measurement! (In this case 'cm')

Therefore, P = 28cm

Which equation has a constant of proportionality equal to 1? A. y=10/11x B. y= 7/8x C. y= 3/15x D. y=x

shtirl [24]

An equation is said to have a constant of proportionality if 'x' is a multiple of 'y' or 'y' is a multiple of 'x'.

Now, we have to determine an equation with constant of proportionality as '1'.

1. $y = \frac{10}{11}x$

This equation has constant of proportionality as ' $\frac{10}{11}$ '.

2. $y = \frac{7}{8}x$

This equation has constant of proportionality as ' $\frac{7}{8}$ '.

3. $y = \frac{3}{15}x$

This equation has constant of proportionality as ' $\frac{3}{15}$ '.

4. $y = x$

This equation has constant of proportionality as '1'.

Option D is the correct answer.

In how many different ways can you answer a multiple choice test that has 5 questions and 3 choices for each answer?

GarryVolchara [31]

Answer:

243

Step-by-step explanation:

If there is one question that has three choices a1, a2, and a3, then there will be 3 i.e. 3¹ different ways of answering which are a1 or a2 or a3.

If there are two questions that have answer choices a1, a2, a3 and b1, b2, b3 then there will be 9 i.e. 3² different ways of answering which are a1-b1, a1-b2, a1-b3, a2-b1, a2-b2, a2-b3, a3-b1, a3-b2, and a3-b3.

Similarly, when there are 5 questions that have three choices each, then there will be 3⁵ i.e. 243 ways of answering options. (Answer)
