Answer:

28 minutes

Step-by-step explanation:

we know that

1) A factory manufactures a metal piece in 32 minutes

2) New technology allowed the factory to cut that time by 8%

Remember that

$100\%-8\%=92\%=92/100=0.92$

In this part 32 minutes represent the 100%

To find out how long it take to manufacture the piece, multiply 32 minutes by the factor 0.92

$32(0.92)=29.44\ min$

3) Then another improvement cut the time by 5%

Remember that

$100\%-5\%=95\%=95/100=0.95$

In this part 29.44 minutes represent the 100%

To find out how long it take to manufacture the piece now, multiply 29.44 minutes by the factor 0.95

$29.44(0.95)=28\ min$

Mademuasel [1]

Answer:

<em> Anna's wand can cast 70 spells</em>

<em></em>

Step-by-step explanation:

Elsa's wand can cast 53 spells

her wand casts 17 fewer cells than her sister Anna's

Amount of spells cast by Anna's wand = ?

We write the question down in the form of an equation

$x - 17 = 53$

where $x$ is the amount of spells Anna's wand can cast.

we then proceed to solve by collecting like terms to different sides of the equation. We'll have

$x = 53 + 17$

which leaves us with

$x = 70$

This means that<em> Anna's wand can cast 70 spells.</em>
