What is the answer to 5/7 + 1/4

Kobotan [32]

Let's look at the two denominators:
7= 7
4= 4
LCM(7,4)= 4*7= 28

5/7+ 1/4
= (5*4)/ (7*4)+ (1*7)/ (4*7)
= 20/28+ 7/28 (common denominator is 28)
= 27/28

The final answer is 27/28~

Each scones sell for $1.50. The chorus profits are 80%of sale. Their current profits are $578.40. How many scones have they sold

slamgirl [31]

Answer:

482 scones.

Step-by-step explanation:

Given:

Cost of each scones = $1.50

Their current profits are $578.40 which is 80% of his total sales.

Question asked:

How many scones have they sold ?

Solution:

Let total number of scones sold = $x$

Cost of 1 scone = $1.50

Cost of $x$ scones = $1.50 $\times x=\$1.5x$ (Unitary method)

80% of his total sales = $578.40 (given)

$\frac{80}{100} \times1.5x=578.40\\0.8\times1.5x=578.40\\1.2x=578.40$

Dividing both sides by 1.2

$x=482\ scones$

Thus, they have sold 482 scones.

Exercise is mixed —some require integration by parts, while others can be integrated by using techniques discussed in the chapte

wlad13 [49]

Answer:

$\frac{2x^{\frac{7}{2}}}{7}+4x+c$

Step-by-step explanation:

We are asked to find the value of the indefinite integral $\int \:x^2\sqrt{x}+4\:dx$ .

Let us solve our given problem applying sum rule as:

$\int \:x^2\sqrt{x}\:dx+\int \:4\:dx$

$\int \:x^2*x^{\frac{1}{2}}\:dx+\int \:4\:dx$

$\int \:x^{\frac{4}{2}}*x^{\frac{1}{2}}\:dx+\int \:4\:dx$

$\int \:x^{\frac{5}{2}}\:dx+\int \:4\:dx$

Now, we will use power rule.

$=\frac{x^{\frac{5}{2}+1}}{\frac{5}{2}+1}}+4x+c$

$=\frac{x^{\frac{7}{2}}}{\frac{7}{2}}+4x+c$

$=\frac{2x^{\frac{7}{2}}}{7}+4x+c$

Therefore, our required integral would be $\frac{2x^{\frac{7}{2}}}{7}+4x+c$ .
