Answer:

Step-by-step explanation:

The question showing a growing function that commonly used in compound interest calculation. The formula for compound interest is:

A = P (1 +r) ^ t

A= amount of the balance after a period of t

P= principal, the initial money deposit

r= rate

t= time

The percent of balance increase should be represented by the rate(r). In this equation, the principal will be 130, (1+r) will be 1.05, and time will be x.

The value of rate (r) will be:

(1+r) = 1.05

r= 1.05-1= 0.05 = 5%

{-210, -156, -366,-471, -108,-627, -579}

Andru [333]

Option D I and IV only is correct option

Step-by-step explanation:

We need to identify that the numbers {-210, -156, -366,-471, -108,-627, -579} belong to which of the following set of numbers.

I. Rational Numbers

II. Natural Numbers

III. Whole Numbers

IV. Integers

We will consider each option

Rational numbers: numbers that can be written by dividing two integers. They can be positive or negative.

all the numbers given can be divided by 1 to make them fractions. So all numbers are rational numbers.

Natural numbers: numbers that are positive integers excluding 0 i.e 1,2,3...

So, the given numbers are not natural numbers

Whole numbers: all natural numbers including 0. These are positive numbers. So, the given numbers are not whole numbers

Integers: it is a whole number (not fraction) that can be positive,negative or zero. So, the numbers given are integers.

So, Option D I and IV only is correct option

a week before election day, 276 out of 450 people said they would vote for the republican candidate. if 15,240 registered voters

Ann [662]

Answer:

(a) $\frac {276}{450}=\frac {y}{15240}$

(b) We cross multiply the probability by the total voters

Step-by-step explanation:

(a)

Probability of getting a republican voter is

$\frac {276}{450}=\frac {138}{225}=\frac {46}{75}$

$\frac {276}{450}=\frac {138}{225}=\frac {46}{75}=\frac {y}{15240}$

These are found by dividing the first numerator and denominator by 2, then by 3

To make it complete, the situation is therefore defined as $\frac {276}{450}=\frac {y}{15240}$ where y is unknown value

(b)

Cross multiplication of the probability and number of voters gives the actual figure of y in the equation formed in part a of the question.

(c)

Since we have 15240 voters who plan to participate in election, we cross multiply to get the approximate number of republican voters which yields

$\frac {46}{75}\times 15240=9347.2\approx 9347$

The drawing of the building, shown below, has a scale of 1 inch to 30 feet. What is the actual height, in feet, of the building?

andreyandreev [35.5K]

Answer:

Actual height of the building is 37.5 feet

Step-by-step explanation:

Formula to be used to get the actual length of the building,

Scale used = $\frac{\text{Dimension of image (on map)}}{\text{Dimension of actual}}$ = $\frac{1}{30}$

By this formula,

$\frac{1.25}{\text{Actual height}}=\frac{1}{30}$

Actual height of the building = 1.25 × 30

= 37.5 feet

Therefore, actual height of the building will be 37.5 feet.
