ValentinkaMS [17]

Answer:

<u>The French restaurant did not use cream this year, due to a menu update.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of cream used by a French restaurant last year = 92.870 ounces

Amount of cream used by the French restaurant this year = 100% less

2.  How much cream did the restaurant use this year?

The answer is zero and we calculated it this way:

92,870 - 100% (92,870) = 92,870 - 92,870 * 1 = 92,870 - 92,870 = 0

<u>The French restaurant did not use cream this year, due to a menu update.</u>

harkovskaia [24]

Answer:

A ) The Amount which will be saved after five years is $ 5742.4

B ) The compound Interest is $ 1742.4

Step-by-step explanation:

The Principal deposited at the end of each year = $ 4000

The rate of interest = 7.5 % compounded annually

The time period = 5 years

From compounded method :

Amount = principal × (1+\dfrac{\textrm rate}{100})^{\textrm time}

or, Amount = $ 4000 × (1+\dfrac{\textrm 7.5}{100})^{\textrm 5}

Or, Amount = $ 4000 × (1.0075)^{5}

or, Amount = $ 4000 × 1.4356

∴ Amount = $ 5742.4

A ) The Amount which will be saved after five years is $ 5742.4

B ) The compound Interest = Amount - principal

   Or, C I = $ 5742.4 - $ 4000 is $ 1742.4    Answer

The length of a rectangle is 5 yd longer than its width.
romanna [79]

Answer:

w = 13yd, l = 18yd

Step-by-step explanation:

let x be width, so x+5 = length

Perimeter is sum of all 4 sides, and since opposite sides equal in rectangle,

P = 2(l+w)

  = 2(x+5 +x)

  = 4x + 10

Since perimeter is give as 62yd, equation is

4x + 10 = 62

4x = 52

x = 13

Which is the area of a circle with a radius of 5 units? (use 3.14 for )?
Sauron [17]
The area of a circle is A=πr². 
Since π is about 3.14 we can substitute that into the equation.
So A=3.14×r²
We can substitute the given radius for r.
A= 3.14 × 5²
When a number is squared, or has the two over it, we multiply it by itself. 
5 × 5= 25
A= 3.14 × 25
Simplify this and the area of the circle is about 78.5
A≈78.5

t=20yrs

SI=PTR/100

=1500*10*20/100

=3000

amount(A)=P+I

=1500+3000
