Today’s cafeteria specials are a turkey sandwich and a pepperoni pizza. During 1st lunch, the cafeteria sold 70 turkey sandwiche
sveticcg [70]

Answer:

$4 and $3

Step-by-step explanation:

First, write out the equations as 70x + 29y = 367 and 70x + 45y = 415. Solve by using the elimination method by subtracting 70x from 70x. 45y minus 29y is equal to 16y. 415 minus 367 is 48. Divide 48 by 16, to get y is equal to get y is equal to three. Y represents pepperoni pizzas, so a pepperoni pizza costs $3. Plug a 3 into any equation for y and solve for x. 29 times 3 is 87. 367 minus 87 is 280. 280 divided by 70 is equal to 4, so x is equal to 4.

The circumference of a circle is 22 cm.
valkas [14]

\bf \: Circumference \:  of  \: a \:  circle = 2\pi \: r

\implies22 = 2 \times  \dfrac{22}{7}  r

\implies22 =  \dfrac{44}{7}  \times r

\implies \: r =  \dfrac{22 \times 7}{44}

\implies \boxed{ r =  \dfrac{7}{2} }

Now,

\bf \: Area \:  of  \: circle = \pi {r}^{2}

\rightarrow \:  \frac{22}{7}   \times  ({ \frac{7}{2}) }^{2}

\rightarrow \frac{22}{ \cancel7}  \times  \frac{ \cancel{49}}{4}

\rightarrow \: 22 \times  \frac{7}{4}

\rightarrow \: 11 \times  \frac{7}{2}

\rightarrow \frac{77}{2}

\rightarrow \: 38.5 \: cm {}^{2}

Area of rectangle = 38.5 cm².
