<h3><u>Given</u>:-</h3>

Volume 6,900 cm^3
Length = 23 cm
Width = 10cm

Height of box ??

<h3><u>Solution</u>:-</h3>

$\\\diamond{\underline{\underline{\sf {\;\; Calculating\; Height\; of \; box :-}}}}\\$

$\\ \pink \star \: \: {\underline{\boxed {\bf{ Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h }}} }\; \red\bigstar \\$

Where,

» l denotes Length
» w denotes Width
» h denotes Height

$\\ \sf \implies \: {Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 23 \: \times \: 10 \: \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 230 \: \times \: h} \\$

$\\ \sf \implies \: { \: h \: = \: \frac{6900}{230} \: } \\$

$\\ \sf \implies \: { \: h \: = \: 30 \: {cm }^{3} \: } \\$

$\\ \implies{\underline{\boxed{\frak { Height = 30 \: cm^3 }}}} \; \purple\bigstar \: \\$

$\\\qquad \rule{120pt}{3pt}\\$

Therefore , the Volume of the Box is 30 cm ³.

Naily [24]

Answer:

The interger is up to 27

Step-by-step explanation:

let X represent the number of people.

For fewer than 28 people, we have;

(X ∠28)

Meaning,

(X ∠28) = (X ≤27)

(X = 1) + (X = 2) + (X = 3) ............+ (X = 27)

1 +1 + 1 +...............(27 times)

Therefore, the interger is up to 27

PLEASE I NEED THIS ANSWER At the local ballpark, the team charges $8 for each ticket and expects to make $1,100 in concessions.

vladimir1956 [14]

Answer:

The answer is d 200

Step-by-step explanation:

with all the information given you come out with the equation

11x+ 1100=3300

Because 8 per ticket plus 3 for each bat equals 11 and then add the 1100 from the concession.

In the end you have to pay the players and the workers so that all equals to 3300

So now you have to solve for x

get x by itself by subtracting 1100 to 3300 which equals 2200

11x=2200

and then get x completely by its self divide 2200/11

and x= 200

hope this helped!
