CAN ANYONE PLEASE (WHO IS AN EXPERT AT MATHEMATICS) HELP ME WITH THIS.

NikAS [45]

Answer:

5 units were bought

Step-by-step explanation:

Firstly, let us calculate the total amount paid

If what was paid was $9.45, this cost includes the price of the coupon subtracted

Returning the coupon price, we have the total as;

9.45 + 0.5 = $9.95

So to get the number bought, we divide this total by the price for one

We have this as;

9.95/1.99 = 5

Find x. Geometry math question please help

Triangle on the right is 30 60 90 triangle

The ratio of short leg : long leg : hypotenuse = a : a√3 : 2a

Given long leg = 8√2

so short leg = 8√2 / √3 = 8√2 *√3 / √3 *√3 = 8√6/ 3

Hypo = 2 (8√6/ 3) = 16√6/ 3

The triangle on the left is 45 45 90 triangle

Ratio of leg : hypotenuse = a : a√2

The hypotenuse of triangle on the right is the leg of triangle on the left

so a = 16√6/ 3

Hypotenuse, x = (16√6/ 3) √2 = 16√12 / 3 = 32√3 / 3

Answer is B.

32√3 / 3

Left to Right

Algebra I

Coordinates (x, y)
Midpoint Formula: $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

Step 1: Define

Point (2, 9)

Point (8, 1)

Step 2: Identify

(2, 9) → x₁ = 2, y₁ = 9

(8, 1) → x₂ = 8, y₂ = 1

Step 3: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

Substitute in points [Midpoint Formula]: $\displaystyle (\frac{2+8}{2},\frac{9+1}{2})$
[Fractions] Add: $\displaystyle (\frac{10}{2},\frac{10}{2})$
[Fractions] Divide: $\displaystyle (5,5)$
