A-5/a divided by 4/a

maria [59]

Answer:

$\frac{a-5}{4}$

Step-by-step explanation:

the given equation is

$\frac{a-5}{a} /\frac{4}{a}$

from the multiplication rules we know that

$\frac{a}{b}/\frac{c}{d}=\frac{a}{b}*\frac{d}{c}$

so for the given equation changing the sidn of division to multiplication

the equation becomes

$\frac{a-5}{a} * \frac{a}{4}$

a cancels out from both numerator and denominator

so it becomes

$\frac{a-5}{4}$

which is the answer

the legth of a rectangle is three times its width. if the width is diminished by 1 m and the legth increased by 3 m, the area wi

Svetllana [295]

Let width of rectangle be "x"
L= 3x W=x
if width is diminished by 1 that means new width = (x-1)
similarly the new length would be (3x+3)
hence (x-1)*(3x+3)=72
(3x^2)-3=72
3x^2=75
x^2=25
x= +/- 5
reject -5 as you cant have negative length
hence x=5
so original dimensions of rectangle is
L= 15m W=5m

chris can be paid in one of two ways. plan a is a salary of $370 per month, plus a commission of 8% of sales. plan b is a salary

JulijaS [17]

Answer:

For a sale value greater than $7200 the plan a is profitable.

Step-by-step explanation:

Let us assume for a sale of $x, Chris will choose plan a.

Now, in plan a, a commission of 8% of sales and $370 per month, is the salary.

So, for a sale of $x the salary is $(370 + 0.08x) per month.

And, in plan b, a commission of 3% of sales and $730 per month, is the salary.

So, for a sale of $x the salary is $(730 + 0.03x) per month.

Now, for selecting plan a, the condition is

(370 + 0.08x) > (730 + 0.03x)

⇒ 0.05x > 360

⇒ x > 7200

Therefore, for a sale value greater than $7200 the plan a is profitable. (Answer)

500 portions of strawberries have been ordered for the tournament, but because of bad weather only

Citrus2011 [14]

We conclude that 375 portions can be sold.

<h3>How many portions can be sold?</h3>

We know that 500 portions have been ordered, but only 5/6 of that was delivered, so the number of delivered portions is:

p = (5/6)*500 = 416.6

Which we can round to the next whole number, 417.

Now we know that 10% of these are given to the players and staff, then the number of portions that can be sold is the 90% of 417, which is:

N = 417*(90%/100%) = 417*0.9 = 375

We conclude that 375 portions can be sold.

What effect does 'h' have on the graph of a parabola?

Kipish [7]

The effect that 'h' have on the graph of a parabola is Horizontal shift or translation .

<h3>What is translation?</h3>

A translation is the movement of a shape up, down , this can also be movement from side to side.

Even though there is movement, its appearance remains the same in any other way, hence, h values cause left or right movement with respect to the graph.
