Answers

as far as I can tell, is simply asking to write two more expressions, that are equivalent to the provided one, namely, grab the provided one and expand it, if you simplify the expanded version, you'd end up with the provided, for example

$\bf \boxed{6a.1}~\hfill \stackrel{changing}{\cfrac{29\cdot 3}{30\cdot 3}}\implies \stackrel{one}{\cfrac{87}{90}}~\hfill \stackrel{changing}{\cfrac{29\cdot 7}{30\cdot 7}}\implies \stackrel{t wo}{\cfrac{203}{210}}\n\n\n\boxed{6a.3}~\hfill \stackrel{ch anging}{\cfrac{15/ 3}{30/ 3}}\implies \stackrel{one}{\cfrac{5}{10}}~\hfill \stackrel{changing}{\cfrac{15/ 5}{30/ 5}}\implies \stackrel{two}{\cfrac{3}{6}}$

so let's do 6a1, 6a3 and 6a5.

$\bf \boxed{6a.1}~\hfill \stackrel{changing}{\cfrac{29\cdot 3}{30\cdot 3}}\implies \stackrel{one}{\cfrac{87}{90}}~\hfill \stackrel{changing}{\cfrac{29\cdot 7}{30\cdot 7}}\implies \stackrel{t wo}{\cfrac{203}{210}} \n\n\n \boxed{6a.3}~\hfill \stackrel{changing}{\cfrac{15/ 3}{30/ 3}}\implies \stackrel{one}{\cfrac{5}{10}}~\hfill \stackrel{changing}{\cfrac{15/ 5}{30/ 5}}\implies \stackrel{two}{\cfrac{3}{6}}$

$\bf \boxed{6a.5}~\hfill \stackrel{changing}{(9\cdot 10)/ (2\cdot 10)}\implies \stackrel{one}{90/ 20}~\hfill \stackrel{changing}{(9\cdot 70)/(2\cdot 70)}\implies \stackrel{two}{630/ 140}$

Step-by-step explanation:

Jamal is making two paintings using canvases that are similar rectangles. The length of the smaller canvas is 3 ft and the width is 5 ft.What is the length of the larger canvas if the width is 10 ft?

Answers

Let's start with what we know:

Smaller canvas:
Length ( $L_(1)$ ) = 3ft
Width ( $W_(1)$ ) = 5ft

Larger canvas:
Length ( $L_(2)$ ) = ?
Width ( $W_(2)$ ) = 10ft

Since these are similar rectangles, we can cross-multiply to calculate the missing length. Here's that formula:

$( L_(1) )/( L_(2) ) = ( W_(1) )/( W_(2) )$
So let's plug it all in from above:

$( 3 )/( L_(2) ) = ( 5 )/( 10 )$
Now we cross multiply by multiplying the top-left by the bottom-right and vice versa:

$(3)(10) = (5)(L_(2))$
$30 = 5L_(2)$
Now divide each side by 5 to isolate $L_(2)$

$(30)/(5) = ( 5L_(2))/(5)$
The 5s on the right cancel out, leaving us with:

$6 = L_(2)$

So the length of the larger canvas is 6 ft

It's not as complicated as you think. The smaller rectangle is 3ft with a width of 5ft. It's asking what the length of the larger canvas is if the width is 10ft. So you pretty much just do 10/5 which is 2 then you multiply 3ft by 2 and you get 6ft.

If you need any help just ask :)

the bill for a pizza was 14.50 . Charles paid for 3/5 of the bill. Show two ways to find how much he paid

Answers

Charles paid $8.70 of the bill.

The first way we can find this is:

= Proportion that Charles paid for x Cost of pizza

= 3/5 x 14.50

= 43.5 / 5

= $8.70

The second way is:

= Cost of Pizza - Proportion that others paid for

= 14.50 - ( (1 - 3/5) x 14.50)

= 14.50 - ( 2/5 x 14.50)

= 14.50 - 5.80

= $8.70

In conclusion, Charles paid $8.70 out of the total bill for the pizza.

Find out more at brainly.com/question/18773038.

Well, if the pizza total was $14.50 and if there were 5 people in total, you'd do 14.50 divided by 5 to get $2.09 per person. If Charles paid 3/5 then do 2.09 times 3 to get $6.27.
