I'm not sure if it's 10x or 10 times a number

10 x (150-3) actually equals 1470
So we have to make (10 x 150) (_ x 3) = 1470
let's call the blank "a"

Now let's solve
(10 x 150) (a x 3) = 1470
10 times 150 equals 1500

1500 x (a x 3) = 1470
3 times a equals 3a because thats the correct way to write it.

1500 x 3a = 1470
-1500 -1500
Now subtract 1500 on both sides of the equal sign

3a = -30
3a ÷ 3 = -30 ÷ 3
1a = -10

Lastly divide 3 on both sides of the equal sign.

a = -10

Andreas93 [3]

The identity Sin(α)/Tan(α) = Cos(α) is valid

Trigonometry is study of triangles. All trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side. Three major of them are as follows :-

Sine Function:

sin(θ) = Opposite / Hypotenuse

Cosine Function:

cos(θ) = Adjacent / Hypotenuse

Tangent Function:

tan(θ) = Opposite / Adjacent

Lets prove this identity by proceeding with the LHS

= Sin(α)/Tan(α)

= Sin(α)/ (Sin(α)/Cos(α)) (Tan(α) = Sin(α)/Cos(α))

= Sin(α)xCos(α) / Sin(α)

= Cos(α)

Hence verified

Julio bought 12 bulbs of jumbo garlic for $11.88. How many bulbs of jumbo garlic can Anjali buy if she has $3.96?

Molodets [167]

Answer:

Anjali can buy 4 bulbs of jumbo garlic if she has $3.96.

Step-by-step explanation:

To calculate how many bulbs of jumbo garlic Anjali can buy with $3.96, we must first calculate the unit rate of the jumbo garlic. Julio buying 12 bulbs of jumbo garlic for $11.88 can be represented as:

$\frac{11.88}{12}$

Divide the fraction by $\frac{12}{12}$ to calculate the unit rate:

$\frac{.99cents}{1bulb}$

So if each bulb of garlic costs $0.99, which we can think of as being $1.00 at the moment, we could figure that Anjali's $3.96 would be closer to $4 than it is to $3, so let's multiply the unit rate by $\frac{4}{4}$ :
