Mr. Bradley purchased 20 trays of flowers. Each tray had 3 dozen flowers. Mr. Bradley's total for all the flowers was 273.60. Al

aev [14]

Answer: Each flower costs $0.38.

Step-by-step explanation:

1 dozen = 12 units

Flowers in each tray = 3 dozen = 3 x 12 = 36

Flowers in 20 trays = 20 x 36 = 720

Price of 20 trays = $ 273.60

Price of each flower = (Price of 20 trays ) ÷ (Flowers in 20 trays)

= 273.60 ÷ 720

= $ 0.38

Hence, each flower costs $0.38.

Use the Distributive Property to expand this expression.<br><br> z(–6.4 – 3.5x)

dedylja [7]

Answer:

$z\left(-6.4\:-3.5x\right)=-6.4z-3.5zx$

Hence, Option 'C' is true.

Step-by-step explanation:

Given the expression

$z\left(-6.4\:-3.5x\right)$

Apply distributive law: $a\left(b-c\right)=ab-ac$

Here: $a=z,\:b=-6.4,\:c=3.5x$

so the expression becomes

$z\left(-6.4\:-3.5x\right)=z\left(-6.4\right)-z\cdot \:\:3.5x$

$=-6.4z-3.5zx$ ∵ $+\left(-a\right)=-a$

Therefore,

$z\left(-6.4\:-3.5x\right)=-6.4z-3.5zx$

Hence, option 'C' is true.

Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements?

Sati [7]

Answer:

The value is $m = 0.9022$

Step-by-step explanation:

From the question we are told that

The length of the treads is $a = 9 \ inch$

The length of the risers is $b = 8.12 \ inch$

Generally the slope of the staircase is

$m = \frac{b}{a}$

=> $m = \frac{8.12}{9}$

=> $m = 0.9022$
