Using proportions, it is found that the length of the rectangle should be of 152 inches.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

His proportion of width-to-length is of 5/8. For this problem, the width is of 95 inches, hence the length is found according to the following<em> rule of three</em>:

5/8 = 95/x

Applying cross multiplication:

5x = 8 x 95

x = 8(95)/5

x = 152 inches.

The length of the rectangle should be of 152 inches.

Answer:

Step-by-step explanation:

The question gives the first equation:

0.05N + 0.10D = 2.20

It can be rewritten as:

0.05$ times the number of nickels plus 0.10$ times the number of dimes is equivalent to $2.20.

Notice that 0.05$ or 5 cents is equivalent to one nickel and 0.10$ or 10 cents is equivalent to one dime.

The question asks for N+D. We know that N stands for the number of nickels Daniel has and D stands for the number of dimes Daniel has. We also know that Daniel <u>only</u> has dimes and nickels in his pocket. Therefore N+D most be equivalent to the <u>total number of coins</u>, which is given in the question to be equal to 23 coins.

Therefore...

N+D = 23

The points (7,r) and (8,9) fall on a line with a slope of 5. What is the value of r?

mrs_skeptik [129]

Answer:

r = 4

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 5

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, r ) and (x₂, y₂ ) = (8, 9)

m = $\frac{9-r}{8-7}$ = $\frac{9-r}{1}$ = 9 - r = 5 ( subtract 9 from both sides )

- r = - 4 ( multiply both sides by - 1 )

r = 4

2. In a given country, records show that of the registered voters, 45% are Democrats, 35% are Republicans, and 20% are independe

Kitty [74]

Answer:

P(R) = 0.14

P(I) = 0.16

P(D) = 0.315

Step-by-step explanation:

Let Democrat = D

Republican = R

Independent = I

If 45% are Democrats, 35% are Republicans, and 20% are independents, then

Total registered voters = 100

In an election, 70% of the Democrats, 40% of the Republicans, and 80% of the independents voted in favor of a parks and recreation bond proposal. That is,

D = 0.7 × 45 = 31.5

R = 0.4 × 35 = 14

I = 0.8 × 20 = 16

If a registered voter chosen at random is found to have voted in favor of the bond, what is the probability that the voter is

a Republican:

P(R) = 14 /100 = 0.14

an Independent

P(I) = 16/100 = 0.16

a Democrat

P(D) = 31.5/100 = 0.315
