Hey! Since the sum of their number is 25 and the difference is 15, we can start by subtracting 25 from 15, to end up with 10. Then, we divide that number up by two because they are two numbers and we get 5. 5 is our first number and if we add 15 back into our second number, we would get 20.

Therefore. The numbers you are looking for is 5 and 20. Where the make the sum of 25 and the difference between them is 15.

Molodets [167]

Answer:

F(3*4)

Step-by-step explanation:

Let\ exponential\ function\ F(x)=a^x\\\\F(3)=a^3\\\\\{F(3)\}^4=\{a^3\}^4\\\\\{F(3)\}^4=a^{3\times 4}...........eq(1)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ as\ (m^n)^k=m^{nk}\\\\Now\ F(3*4)=a^{3\times 4}.......eq(2)\\\\From\ eq1\ and\ eq2\\\\\{F(3)\}^4=F(3\times 4)\\\\\{F(3)\}^4=F(3*4)

Beau's recipe for granola bars calls for 3 1/2 cups of oatmeal. He only has a 1/6 cup scoop. How many scoops of oatmeal will he
Drupady [299]

There will be \boxed{\bf 21} scoops of oatmeal to complete the recipe.

Further explanation:

Given that Beau’s recipe of granola bars contains 3\frac{1}{2} cups of oatmeal.

Beau’s has only \frac{1}{6} cup scoop.

Our aim is to find the number of scoops of oatmeal Beau’s needed to complete the recipe for granola bars.

Total cups of oatmeal are 3\frac{1}{2}.

First we have to convert the total cups of oat meal to proper fraction.

\begin{aligned}\text{Cups of oatmeal for the recipe}&=\dfrac{(3\cdot 2)+1}{2}\\&=\dfrac{6+1}{2}\\&=\dfrac{7}{2}\end{aligned}  

There is only \frac{1}{6} cup scoop.  

Since there are \frac{7}{2} cups of oatmeal and \frac{1}{6} cup scoop, therefore, number of scoops required to complete the meal are calculated as follows:

\begin{aligned}\text{Number of scoops required}&=\dfrac{\frac{7}{2}}{\frac{1}{6}}\\&=\dfrac{7}{2}\cdot 6\\&=7\cdot 3\\&=21\end{aligned}  

The total number of scoops is obtained in whole number; therefore, this is our final answer.

Therefore, \boxed{\bf 21} scoops of oatmeal are needed by Beau’s to complete the recipe of granola bars.

A point in rectangular coordinates is given. Convert the point to polar coordinates. Round your answers to two decimal places.
postnew [5]

Answer:

(√74, 54.46°)

Step-by-step explanation:

The rectangular coordinate point is given as; (5, 7)

Now, converting rectangular coordinates to polar coordinates is done by;

(r, θ)

Where, r is the magnitude while θ is the angle

r = √(5² + 7²)

r = √74

tan θ = (7/5)

θ = tan^(-1) 1.4

θ = 54.46°

Thus,polar coordinate is; (√74, 54.46°)
