Answer:

x = 40

Step-by-step explanation:

x/(2 1/2) = 16/1

x/(5/2) = 16

Multiply both sides by 5/2.

x = 16 * 5/2

x = 80/2

x = 40

Answer: x = 40

What is 7/8 plus 4/6 equal

Alekssandra [29.7K]

First, find a common denominator (preferably the LCD): 8 and 6 both factors of 24, which is also the LCM, so we'll use that.

Second, manipulate the numerators so that the fractions are equivalent to the ones you started-out with: In order to make 7/8 equal to a fraction that has a denominator of 24, we have to multiply the numerator by 3, since we multiplied the denominator by 3 to make it 24. We will do the same process for the fraction 4/6.

Thus far, we should have 21/24 plus 16/24.

Next, all we have to do is add the numerators together, and keep the denominator. You should end-up with 37/24. If your teacher doesn't want an improper fraction, we can simplify this by dividing 37 by 24, which gives us 1, and then subtracting 24 from 37 in order to find-out how many twenty-fourths we have left over. Since this is equal to 13, the mixed-number form of the answer would be 1 13/24 ("one and thirteen twenty-fourths").

Ellen has recently inherited $5400, which she wants to deposit into a CD account. She has determined that her two best bets are

trapecia [35]

Answer:

Interest for case 2 is more i.e at interest rate 5.3% compounded quarterly

Step-by-step explanation:

Data provided in the question:

Principle amount = $5400

let us calculate the interest for t = 1 year

Case 1:

Rate of interest, r = 4.1%

Compounded semi-annually i.e number of periods, n = 2

Therefore,

Interest = Principle × $\left( 1 + \frac{r}{n} \right)^{\Large{n\times t}}$ - Principle

on substituting the respective values, we get

Interest = $5400 × $\left( 1 + \frac{0.041}{2} \right)^{\Large{2\times1}}$ - $5400

or

Interest = $5400 × 1.0205² - $5400

or

Interest = $5623.67 - $5400

= $223.67

Case 2:

Rate of interest, r = 5.3% = 0.053

Compounded quarterly i.e number of periods, n = 4

Therefore,

Interest = Principle × $\left( 1 + \frac{r}{n} \right)^{\Large{n\times t}}$ - Principle

on substituting the respective values, we get

Interest = $5400 × $\left( 1 + \frac{0.053}{4} \right)^{\Large{4\times1}}$ - $5400

or

Interest = $5400 × 1.01325⁴ - $5400

or

Interest = $5691.94 - $5400

= $291.94

Hence,

interest for case 2 is more i.e at interest rate 5.3% compounded quarterly

Option a: multiply $\frac{2}{5}$ by 4.

Explanation:

The expression is $\frac{2}{5} \div \frac{1}{4}$

Dividing the two fractions which is the same as multiplying the first fraction by the reciprocal value of the second fraction.

Hence, it can be written as

$\frac{2}{5} \times \frac{4}{1}=\frac{8}{5}$

Hence, $\frac{8}{5}$ is the quotient.

Option a: multiply $\frac{2}{5}$ by 4.

To determine the quotient, let us multiply the term $\frac{2}{5}$ by 4, we get,

$\frac{2}{5} \times 4=\frac{8}{5}$

Hence, $\frac{8}{5}$ is the quotient.

Thus, Option a is the correct answer.

Option b: multiply $\frac{2}{5}$ by $\frac{1}{4}$

To determine the quotient, let us multiply the term $\frac{2}{5}$ by 4, we get,

$\frac{2}{5} \times \frac{1}{4}=\frac{1}{10}$

$\frac{1}{10}$ is not the quotient. Since, the quotient is $\frac{1}{10}$ which is not equivalent to $\frac{8}{5}$ and hence we cannot multiply $\frac{2}{5}$ by $\frac{1}{4}$

Hence, Option b is not the correct answer.

Option c: multiply $\frac{5}{2}$ by $\frac{1}{4}$

To determine the quotient, let us multiply the term $\frac{5}{2}$ by $\frac{1}{4}$ , we get,

$\frac{5}{2} \times\frac{1}{4}=\frac{5}{8}$

$\frac{5}{8}$ is not the quotient. Since, the quotient is $\frac{5}{8}$ which is not equivalent to $\frac{8}{5}$ and hence we cannot multiply $\frac{5}{2}$ by $\frac{1}{4}$

Hence, Option c is not the correct answer.

Option d: multiply $\frac{5}{2}$ by 4

To determine the quotient, let us multiply the term $\frac{5}{2}$ by 4, we get,

$\frac{5}{2} \times4=10$

10 is not the quotient. Since, the quotient 10 which is not equivalent to $\frac{8}{5}$ and hence we cannot multiply $\frac{5}{2}$ by 4.

Hence, Option d is not the correct answer.

Find the area of the circle.. PLEASE HELP

Leno4ka [110]

Answer:

The area is 154 cm²

Step-by-step explanation:

Since the formula for the area of a circle is pi times the radius squared, divide the diameter in half to get the radius (7). Then, square the radius (49). Next, multiply that by pi (153.938). After that round to the nearest whole number (154). Hope that helps!
