Answer:

17 tins

Step-by-step explanation:

Split the figure into two:

The top rectangle and the bottom rectangle

Now find area of the top one.

=> A = lb

=> 17 x 9.7

=> 164.9 m²

Now the bottom one.

=> A = lb

=> A = 15.9 x 2.3

=> A = 36.57 m²

So, total area is :-

= 164.9 + 36.57

= 201.47 m²

No. of tins = 201.47/12

= 16.78

= 17 tins (to cover remaining area)

Kara used the linear model y=45,000+ 0.05x to predict her total salary from achieving total sales of x.

hoa [83]

Answer:

45,000 is the starting salary with zero sales

.05 is the amount multiplied by the number of sales that is added to her salary

For each sale we add .05 to her salary

Step-by-step explanation:

y = 45,000 +.05x

Rewriting as

y = .05x +45,000

This is in slope intercept form ( y=mx+b) where m is the slope and b is the y intercept

.05 is the slope and 45,000 is the y intercept

45,000 is the starting salary with zero sales

.05 is the amount multiplied by the number of sales that is added to her salary

For each sale we add .05 to her salary

What’s 45 divided by 14.04

Vladimir79 [104]

Answer:

3.205

Step-by-step explanation:

convert the decimal number to a fraction

$45 \div \frac{351}{25}$

To divide by fraction, multiply by the reciprocal of that fraction

$45 \times \frac{25}{351}$

Reduce the numbers with the greatest common divisor 9

$5 \times \frac{25}{39}$

Calculate the product

$\frac{125}{39}$

Now turn it to a decimal which will be

$3.20513$
