2. Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles
hold?

Answers

Answer:

16 1/2 gallons of water.

Step-by-step explanation:

Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.

Jim is making salsa. His recipe calls for 3 1 3 cups of tomato sauce for every 1 6 cups of cilantro. If Jim has 1 cup of cilantro, how many cups of tomato sauce will he need?

Answers

Answer: 20 cups of tomato

Step-by-step explanation:

From the question, we are informed that Jim is making salsa and that his recipe calls for 3 1/3 cups of tomato sauce for every 1/6 cups of cilantro.

If Jim has 1 cup of cilantro, thus simply means that he has multiplied the previous cup of cilantro by:

= 1 ÷ 1/6

= 1 × 6/1

= 6

Therefore, we would also multiply the cups of tomato by 6. This will be:

= 3 1/3 × 6

= 10/3 × 6

= 20 cups of tomato

Step-by-step explanation:

13=blue blankets 7=red blankets

First, we need to know how many blankets there are in total.

13+7=20

Now, we don't need the seven anymore. Our ratio is blue blankets to total blankets.

13/20

Now, we need to know how many blue blankets there are in percentage.

13/20 = x/100

Next step: 13 times 100 is divided by 20

x= 13(100)÷20

x=1300÷20

x= 65

James is a botanist studying the production of beans by two types of bean plants.
He noticed that the string bean plant produced 30% more beans than the lima bean
plants. Based on James' observation, if the string bean plants produced 130 string
beans, how many lima beans did the lima bean plant produce?

Answers

Answer:

100 lima beans

Step-by-step explanation:

We can write an equation with s = string beans and l = lima beans:

s = 1.3l

We can now plug in 130 = s to get:

130 = 1.3l

We divide both sides by 1.3 and get:

100 = l

That means the lima bean plant produced 100 lima beans

Answer:

91

Step-by-step explanation:

130 * 30% =

130 * 0.3 =

39

130 - 39 = 91

the sum of two and a number is less than five

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the English statement

''The sum of two and number is less than five''.

Let us breakdown the statement.

Let 'n' be the number. The sum of two and number = 2 + n

We know that the less than symbol is denoted by '<' which is used for comparison.

Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:

2 + n < 5

Let us solve the algebraic expression.

[tex]2+n<5[/tex]

Subtract 2 from both sides

[tex]2+n-2<5-2[/tex]

Simplify

[tex]n<3[/tex]

Thus, the solution is:

[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]

Do these ratios form a proportion 12/16 and 15/20

Answers

Answer:

This is a proportion

Step-by-step explanation:

Cross multiply:

12 * 20 = 16 * 15

Simplifying:

12 * 20 = 16 * 15

Multiply 12 * 20

240 = 16 * 15

Multiply 16 * 15

240 = 240

Add '-240' to each side of the equation.

240 + -240 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 0

Solving

0 = 0

Now, however, energy andenvironmental challenges are encouraging new building materials, new ways to design buildings, and new respect for nature.How would Mother Nature design a building?Through 4 billion years of evolution, organisms have come up with some neat designs. Architects are beginning to look to nature for cluesto building sustainabilityPerhaps most famous among biologically informed buildings is the Eastgate shopping center and office building in Harare, Zimbabwe. Thedesign was inspired by African termite mounds, where termites maintain a constant temperature of 87 degrees (to preserve a fungus that theycultivate to eat) by opening and closing flues that vent hot air.The concrete Eastgate building has no air-conditioning system. During the night, big fans draw cool outside air up through spaces betweenthe building's floors. During the day, smaller fans drive the warmer outside air through the same spaces, where the cool concrete moderates thetemperature. As the air warms, it rises through 48 round brick funnels and out the roof. Fresh air circulates through the building twice an hourduring the day. The building reportedly uses only 10 percent of the energy that a conventional building of the same size would use.How about building materials inspired by nature?
