Answer:

Well 5/6 divided by 2/6. You are gonna have to find the answer first before you start to write this down. Here is an example. So since this is a 4 I'm going to divide the box into 4 vertical columns and they do not need to be perfect and now I'm going to divide. Since the divisor is 5 I'm going to divide it into five rows. "How many times does 4 go into 5?" is the same as asking "How much is 5 divided by 4?" Thus, the answer can be calculated as follows:

5/4 = 1.25

"How many times does 4 go into 5?" is also the same as asking "What (x) do you multiply by 4 to get 5?" We solve the problem with an easy algebra equation:

4(x) = 5

x = 1.25

Tip: When you get a question like "How many times does 4 go into 5?", just think of it as how many times you can fit 4 into 5.

Step-by-step explanation: Easy kind of...

Bethany sells roses and petunias. The expression 3r+2.5p3r+2.5p3, r, plus, 2, point, 5, p gives the cost (in dollars) of rrr ros

Vaselesa [24]

Answer:

I think the equation is written as 3r + 2.5p, where r is the number of roses and p is the number of petunias. To find the total cost, substitute 777 to r and 888 to p. The total cost would then be:

Total Cost = 3r + 2.5p

Total Cost = 3(777) + 2.5(888)

Total Cost = 4551

The total cost would be $4,551.

Solve for x. Round to the nearest tenth, if necessary.

Answer:

$\boxed {\boxed {\sf x \approx 1.9}}$

Step-by-step explanation:

We are asked to find x, a missing side in a triangle.

This is a right triangle because there is a small square in the corner representing a 90 degree or right angle. Therefore, we can use right triangle trigonometry. The three main functions are:

sinθ= opposite/hypotenuse
cosθ= adjacent/hypotenuse
tanθ= opposite/adjacent

Examine the triangle. We will use angle S, measuring 54 degrees, for theta. Side QR, measuring x, is opposite angle S. Side QS, measuring 2.3, is the hypotenuse because it is opposite the right angle. Since we have the opposite and hypotenuse, we will use sine.

$sin \theta = \frac {opposite}{hypotenuse}$

θ= 54
opposite= x
hypotenuse = 2.3

$sin (54)= \frac{ x}{2.3}$

We are solving for x, so we must isolate the variable. It is being divided by 2.3 The inverse operation of division is multiplication, so we multiply both sides by 2.3

$2.3* sin (54)= \frac{x}{2.3}*2.3$
