Elisa is making strawberry shortcake. One serving of strawberry shortcake requires one third cup of strawberries and one shortbr
Kisachek [45]

Given, To make a strawberry shortcake for one person, we need :

▪︎\frac{1}{3} cup of strawberry

▪︎one shortbread biscuit

Quantity of strawberries Elisa has = 3 cups

Number of shortbread biscuits she has = 12

Number of shortcakes she can make :

= \tt3 \div \frac{1}{3}

=  \tt\frac{3 \times 3}{1}

\color{plum} =\tt 9 \: people

Thus, Elisa can serve strawberry shortcakes to 9 people.

With 12 dozen shortbread biscuits she can serve 12 people.

Quantity of strawberries needed to serve 12 people :

=\tt \frac{1}{3}  \times 12

=\tt  \frac{12}{3}

\color{plum} = \tt4 \: cups

<h3>○=> Therefore :</h3>

▪︎Elisa can serve strawberry shortcakes to <u>9 people</u>.

▪︎Elisa will need <u>4 cups of strawberries</u> if she wants to use all dozen shortbread biscuits.

Describe the nature of the roots for this equation
vitfil [10]

First, fint the roots of the equation 2x^2+5x-7=0.

1.

D=5^2-4\cdot 2\cdot (-7)=25+56=81,\\\sqrt{D}=\sqrt{81}=9,\\ \\x_1=\dfrac{-5-9}{2\cdot 2}=-\dfrac{14}{4}=-3.5,\\ \\x_2=\dfrac{-5+9}{2\cdot 2}=\dfrac{4}{4}=1.

2. You can see that this equation has two different real roots. Note that you can make this statement without finding roots, only knowing the value of discriminant: since D=81>0, then the equation has two different real roots.

A car rental agency charges $75 per day, which includes 100 miles. For each mile over 100 miles, there is an additional cost of
Archy [21]

The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160

According to the question;

  • The agency charges $75 per day, which includes 100 miles.

  • Additionally, the agency charges $0.35 per mile for each additional mile;

a) The equation relating m , the number of miles driven, if the total cost for a one-day rental was $131 is therefore;

  • $0.35m + $75 = $131.

b) To find the solution to the equation;

  • $0.35m = $131 - $75

  • $0.35m = $56

  • m = $56/$0.35

m = 160.

The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160.
