Answer:

The scale is: 1 cm = 3.26 meter

Step-by-step explanation:

Given

Height of Pyramid in Painting = $H_p = 45 cm$

Actual Height of Pyramid = $H_a = 146.5m$

In order to find the scale, we can find the ratio between actual height and height in painting.

The ratio can be found by dividing the actual height by height in painting

$Scale = \frac{H_a}{H_p}\\= \frac{146.5}{45}\\=3.25555 m/cm$

Rounding off to nearest hundredth

= 3.26

This means that the scale is:

1 cm = 3.26 meter

Answer:

Average is less than 65, therefore, shop did not meet the target.

Step-by-step explanation:

The time series graph gives some information about the number of umbrellas sold in a shop in the first six months of 2015.

From the given graph it is clear that the number of umbrellas sold in Jan, Feb, Mar, Apr, May, June are 54, 84, 72, 94, 52, 26 respectively.

Average sales is

$Average=\dfrac{\text{Sum of number of umbrellas sold in 6 months}}{6}$

$Average=\dfrac{54+84+72+94+52+26}{6}$

$Average=\dfrac{382}{6}$

$Average=63.67$

Since, average is less than 65, therefore, shop did not meet the target.

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes,and 20 pages in 30 minutes. Is this a proportional relatio

maria [59]

Answer:

y = 2/3x

Step-by-step explanation:

Reading rate is y pages per x minutes and proportional relationship formula is:

y = kx

The coefficient is:

k = y/x

Let's verify if the given numbers fit into the same relationship:

12/18 = 2/3
8/12 = 2/3
20/30 = 2/3

We confirm all same and it means k = 2/3

Required equation is:

y = 2/3x

This represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages
