The expression for rate per hour is \frac{340}{45}\times 60.

Explanation:

Given:

A machine paints 340 toy boats in 45 minutes.

To Find:

Expression equals the rate per hour?

Solution:

Finding the expression for rate per minute:

\text{{The rate per minute expression}} =\frac{\text{{ (number of toys painted in time given)}}}{\text{{(number of minutes taken)}}}

So, rate per minute expression is \frac{(340 toys)}{(45 minutes)} = \frac{340}{45}

Then, rate per hour expression \text{{rate per minute}}\times 60 minutes

So, rate per hour expression is \frac{340}{45}\times60 minutes= 453.334 toys per hour.

Hence, the expression for rate per hour is \frac{340}{45}\times 60

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 8.4 years, and standard deviation of
QveST [7]

Answer:

7.35 years

Step-by-step explanation:

Given that :

mean = 8.4

standard deviation = 0.6

From the negative z tables, the corresponding data for 0.04 = -1.75

So, using the z-score formula:

z = \dfrac{x  - \mu}{\sigma}

-1.75 = \dfrac{x - 8.4}{0.6}

-1.75 × 0.6  = x - 8.4

- 1.05 = x - 8.4

x = -1.05 + 8.4

x =  7.35 years

the shortest lifespan will last less than 7.35 years

∴ the longest 4% will have lifespans longer than x = 8.4 + 1.75(0.6)

= 9.45 years

Find the area of the trapezoid. Leave your answer in simplest radical form.
Zanzabum

Answer:

A)94.5 cm

Step-by-step explanation:

height = 9cm

Base 1 = 5cm

Area of a Trapezoid = 1/2 × (b1 + b2)h

h = 9cm

b1 = 5cm

b2 = (9 cm + 5cm + 2cm) = 16cm.

Area of Trapezoid

= 1/2 (5 + 16) × 9

= 1/2 × 21 × 9

= 94.5 cm

Option A is the correct answer
