Matthew decided to bake cupcakes for the school fundraiser. He wants to make 2 dozen cupcakes--one dozen strawberry and one doze

Alchen [17]

Answer:

$4+c=2\frac{1}{4}+2\frac{1}{3},\\\\\frac{7}{12}\:\text{more cups of flour}$

Step-by-step explanation:

The total amount of flour, in cups, Matthew needs is equal to $2\frac{1}{4}+2\frac{1}{3}=4\frac{7}{12}$ . Because he only has 4 cups, we can write the following expression to determine how many additional cups of flour he needs:

$4+c=2\frac{1}{4}+2\frac{1}{3},\\\\4+c=\frac{7}{12}, \\\\c=\boxed{\frac{7}{12}\:\text{more cups of flour}}$

Solve for the area:<br><br><br><br> 32 cm^2<br> 16 cm<br> 32 cm<br> 16 cm^2

MA_775_DIABLO [31]

<h3>Given : </h3>

Base of triangle = 8 cm
Height of triangle = 4 cm

$\\$

Area of triangle = ?

$\\$

<h3>Solution :</h3>

As, we have :

Base of triangle, b = 8 cm
Height of triangle, h = 4 cm

$\\$

So, to find area of triangle we have a formula :

$\large \underline{\boxed{\bf{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}$

$\tt : \implies Area = \dfrac{1}{2} \times 8 \: cm \times 4 \: cm$

$\tt : \implies Area = \dfrac{1}{2} \times 32 \: cm^2$

$\tt : \implies Area = \cancel{\dfrac{32}{2}} \: cm^2$

$\tt : \implies Area = 16 \: cm^2$

$\\$

Hence, area of given triangle is 16 cm².
