You’re trying to find the better buy so you want to find out how much you’re paying per unit (in this case kg)

So you divide the price by the unit (kg)

And find the better buy by looking at which price is cheapest.

Your answer is the 7.48 kg bag

Hope this helps and good luck!!

90+ POINTS PLEASE HELP Choose one problem below and use trigonometry to solve for a missing angle x of the right triangle

d1i1m1o1n [39]

Answer:

$x\approx49.3266\textdegree$

Step-by-step explanation:

So we want to find Angle x.

Note that we already know the side length of the side opposite to Angle x.

We also know that the hypotenuse is 56.3.

Therefore, we can use the sine function. Recall that:

$\sin(x)=\frac{\text{opposite}}{\text{hypotenuse}}$

The opposite side is 42.7. The hypotenuse is 56.3. Substitute:

$\sin(x)=\frac{42.7}{56.3}$

Take the inverse sine of both sides.

$\sin^{-1}(\sin(x))=\sin^{-1}(\frac{42.7}{56.3})$

The left side cancels:

$x=\sin^{-1}(\frac{42.7}{56.3})$

Use a calculator. Thus:

$x\approx49.3266\textdegree$

And that's our answer :)

The prime factorization of a number is 23 times 32 times 5. Which is a new statement about the factors of the number?

Zanzabum

32 is not a prime number.

32 = 2 · 2 · 2 · 2 · 2

Correct the prime factorization is:

23 · 5 · 2 · 2 · 2 · 2 · 2

Five double-digit numbers We have five consecutive positive double-digit integers. If we swap places on the numbers in the large

barxatty [35]

Answer:

Step-by-step explanation:

Let the numbers are:

x, x + 1, x + 2, x + 3 and x + 4

Their sum is 5x + 10
Their mean is (5x + 10)/2 = x + 2

If we swap the digits on the largest number, the sum increases by 1 more than x + 2

We are looking for the number x + 4 = ab such that:

ba - ab = ab - 2 + 1
ba = 2ab - 1
10b + a = 2(10a + b) - 1
10b + a = 20a + 2b - 1
8b = 19a - 1
19a = 8b + 1

By trial method we get the solution:

a = 3, b = 7

Since x + 4 = 37, the lowest number is:

x = 37 - 4 = 33

Lets verify:

33, 34, 35, 36, 37

The sum is:

5*33 + 10 = 175

The mean is:

Change the largest number tp 73 and find the sum again:

175 + (73 - 37) = 175 + 36 = 175 + 35 + 1

The sum has increased by 1 more than 35
