castortr0y [4]

First we have 2 types of units of measurement so let’s make all the same type.
600mm= 60 cm
500mm= 50 cm
Tray dimensions are 60 by 50 cm and is a rectangle

Cake tin is round and has diameter 25 cm

We can fit 2 rows and 2 columns of tins
Since (25+25) is less or equal to 50
And (25+25) is less or equal to 60

Answer 4 cake tins

Jim went by bus to visit his uncle. He left at 10 A.M. and arrived at 4 P.M. The bus traveled 270 mi. What was its average speed

Feliz [49]

Answer:

Average speed, S = 45 mph

Step-by-step explanation:

<u>Given the following data;</u>

Take-off time = 10 AM

Arrival time = 4 PM

Distance = 270 miles

To find the average speed of the bus;

First of all, we would determine the total time.

10 AM to 4 PM = 6 hours

Total time = 6 hours

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting into the formula, we have;

$Speed = \frac{270}{6}$

<em>Average speed, S = 45 mph</em>

<em />

<em>Therefore, the average speed of the bus is 45 miles per hour.</em>

Answer:

$14,747 at 9%
$12,129 at 5%

Step-by-step explanation:

Let x represent the amount invested at 9%. Then the difference in interest amounts is ...

(9%)x -(5%)(26876 -x) = 720.78 . . . . . assuming a 1-year investment

0.14x -1343.80 = 720.78 . . . . . . . . . simplify

0.14x = 2064.58 . . . . . . . . . . . . . . add 1343.80

x = 14,747 . . . . . . . . . . . . . . . . divide by 0.14

$14,747 is invested at 9%; $12,129 is invested at 5%.
