Eric and Mark were at a ball game and visited the concession stand. They each got a hamburger, and Mark got lemonade and some co
EastWind [94]
So here is the answer. Given that both Eric and Mark got a hamburger which is $4 each. Mark got a lemonade and some cotton candy which costs $5. 
So this gives them a total of $4, $4, $5, $?(lemonade). Partial sum is $13 without the lemonade. Since Eric got a $2, the total bill was deducted with $2 and the rest of the amount is $14.50. Therefore, the total bill would have been $16.50. So $16.50 minus $13 (partial sum) is $3.50. So the lemonade costs $3.50. Hope this helps.

Find the surface area of the cylinder
Alik [6]

Answer:

Surface Area = 282.6 cm²

Step-by-step explanation:

Formula: SA = 2\pirh + 2\pir²

SA = 2\pirh + 2\pir²

SA = 2(3.14)(5)(4) + 2(3.14)(5)

SA = 2(3.14)(5)(4) + 2(3.14)(25)

SA = 125.6 + 157

SA = 282.6 cm²

Advocard [28]

Answer:

1.

\frac{n^{2} - 1 }{2}

2.

\sqrt{29}

Step-by-step explanation:

Area of triangle=1/2×b×h

=

\frac{1}{2}  \times (n - 1)(n + 1)

\frac{( {n}^{2} + n - n - 1) }{2 }

\frac{ {n}^{2} - 1 }{2}

2. Area of triangle=14

\frac{ {n}^{2} - 1 }{2}  = 14

{n}^{2}  - 1 = 28

{n}^{2}  = 29

n =  \sqrt{29}

Together, Dante and Mia have a total of 350 pennies in their piggy banks. After Dante lost ½ of his pennies and Mia lost ⅓ of he
natta225 [31]

Answer:

Altogether they lost 150 pennies.

Step-by-step explanation:

X = Dante's pennies

Y = Mia's pennies

X + Y = 350                                       1/2 X = 2/3 Y

                                                                X = 4/3 Y

4/3 Y + Y = 350

7/3 Y = 350

Y = 350 * 3/7

Y = 50 * 3

Y = 150

X + 150 = 350

X = 200

                                                     1/2 * 200 = 2/3 * 150

                                                       100 .      =   100

1/2 * 200 = 100 -> Dante lost 100 pennies

1/3 * 150 = 50 -> Mia lost 50 pennies

Altogether they lost 150 pennies.
