A The number of tropical fish that an aquarium can hold depends on the volume of the fish tank. The interior dimensions of a fish tank are 30 cm, 90 cm, and 70 cm. Each fish requires 27000 cubic centimeters of water. How many tropical fish will this fish tank hold?a. 8
b. 6
c. 9
d. 7

Answers

Answer 1

Answer:

Step-by-step explanation:

We need to first of all find the volume of the fish tank. The most probable shape the ship tank can have is that of a cuboid.

The volume of a cuboid is l * b * h

And this is equals 30cm * 70cm * 90cm = 189,000 cubic centimeters

The number of fish the tank can contain can be obtained by dividing the volume by the volume occupied by a single fish.

This is 189,000/27000 = 7

During the first week of the year, Angelina's dad give her $10 and says that he will give her $10 more each week for the rest of the year. At the end of the year, how much money will Angelina receive from her dad? (Hint : 1 year = 52 weeks) Make a table to show the pattern, and explain your answer.

Answers

The amount Angelina will have at the end of the year is $520.

What are Mathematical operators?

A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:

Operands: Operands are the numbers that an operator uses. The terms that are given to the operands vary according to the kind of operation.

Given money received by Angelina in the first week = $10

and money she will get each week for rest of the year = $10

amount in first week = $10

amount in second week = $10 + $10 = $20

amount in third week = $20 + $10 = $30

amount is week 52 = 52 x $10 = $520

table for the week and money

week 1 2 3 4 5 6 ........ 52

money $10 $20 $30 $40 $50 $60 ....... $520

Hence the amount after 1 year will be $520.

$520. for the table just make 2 columns. one side is 1-52 for each week of the year and the other side will be the total amount for that week. ex: week 1=$10, and week 2=$20, etc.it should be self explanatory by that point.

Choose the correct product of (2x + 10)2.4x2 − 100
4x2 + 40x + 100
4x2 + 100
4x2 − 40x + 100

Answers

Answer: 4x² + 40x +100

(2x+10)(2x+10)
4x2 + 20x + 20x +100
4x2 + 40x + 100

Answer:

$(2x+10)^2=4x^2+40x+100$

Step-by-step explanation:

Given the expression

$(2x+10)^2$

we have to simplify the above expression.

By identity

$(a+b)^2=a^2+2ab+b^2$

Put a=2x and b=10

$(2x+10)^2=(2x)^2+2(2x)(10)+10^2$

$(2x+10)^2=4x^2+40x+100$

Option B is correct.

a delivery truck traveled 324 miles on 18 gallons of gas how far can be traveled on 41 gallons of gas?

Answers

324 miles divided by 18 gallons = 18 miles per gallon (mpg)

Therefore, 41 gallons x 18 mpg = 738

Final answer:

The delivery truck can travel 738 miles on 41 gallons of gas, assuming it maintains the same fuel efficiency. This is calculated by first finding the mileage per gallon (miles driven divided by gallons used), then multiplying that by the number of gallons.

Explanation:

The situation given can be solved by using unit rate or sometimes referred to as proportion. The delivery truck traveled 324 miles on 18 gallons of gas. We'll first find out the mileage per gallon and then use that to compute how far it could go on 41 gallons.

First, we divide the total miles by the total gallons to get miles per gallon: 324 miles / 18 gallons = 18 miles per gallon.
Then, multiplies the miles per gallon by the quantity of gallons you want to know: 18 miles per gallon * 41 gallons = 738 miles.

So, a delivery truck that traveled 324 miles on 18 gallons of gas could travel 738 miles on 41 gallons of gas, assuming the truck maintains the same fuel efficiency.
