The volume V​ (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2​ . Solve the formula for r​ . Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.

Answers

Answer 1

Answer:

a) r = √V/6π

b) r = 8 inches

Step-by-step explanation:

a) The volume V​ (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2​ . Solve the formula for r​ .

Solving for r means making r the subject of the formula

= V=6πr²

Divide both side by 6π

V/6π = 6πr²/6π

r² = V/6π

r = √V/6π

b) Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.

r = √V/6π

V = 1206 ft³

r = √1206/6π

r = √(63.98028712294193)

r = 7.9987678503 inches

Approximately r = 8 inches

1. Alyssa is twice as old as Brittany, and Jazmin is 15 years older than Alyssa. If Jazmin is 45 years old, how old is Brittany?
Write two algebraic equations, let represent Alyssa’s age in years and represent Brittany’s age in years.
Tysm if u do this <3

Answers

Answer:

Brittany is 15 years old

Step-by-step explanation:

The way we get the answer is by getting the age of Alyssa 45-15=30 as, Jazmin is 15 years older than Alyssa and then we can see that Alyssa is twice as old as Brittany so we divide Alyssa's age by two. 30÷2=15 and we get Brittany's age which is 15 years old.

she is 15 years old ( Brittany)

Leonard made the 3-d shape below for an art project. He wants to paint it blue.
How many square centimeters of paint does he need to paint the outside of every
side except for the bottom?
10 cm
6 cm

Answers

Answer:

90 [tex]cm^{2}[/tex] of blue paint

Step-by-step explanation:

From the given diagram, the sides have the same dimensions and the shape of a triangle.

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

Given that, the base of each side = 6 cm, and the height = 10 cm.

Then,

Area of each side of the shape = [tex]\frac{1}{2}[/tex] x 6 x 10

                                              = 30 [tex]cm^{2}[/tex]

Since Leonard wish to paint only the 3 sides and not the bottom part of the shape, the amount of paint required can be determined as;

3 x area of each side = 3 x 30

                                   = 90 [tex]cm^{2}[/tex]

Leonard would need 90 [tex]cm^{2}[/tex] of paint to paint the sides of the shape.

Answers

The quadratic function [tex]f(x)[/tex] has one zero at [tex]x=-5[/tex] and a turning point at [tex](3,10)[/tex]. The value of other zero is [tex]11[/tex].

What is Quadratic function?

The Quadratic function [tex]f(x)[/tex] is a polynomial function with one or more variables in which the highest power of the variable is two. i.e.  [tex]f(x) = ax^{2} + bx + c[/tex]

What are zeros?

The zeros of a polynomial [tex]f(x)[/tex] are all the [tex]x[/tex]-values that make the polynomial equals to zero. i.e. [tex]f(x)=0[/tex]

What is turning point?

A turning point is a point at which the derivative changes sign.

We have,

One zero is  [tex](-5)[/tex],

Let other Zero be [tex]"a"[/tex],

Turning point at [tex](3,10)[/tex].

i.e. [tex]x=3[/tex] and [tex]y=10[/tex]

Since the difference between [tex]3[/tex] and [tex](-5)[/tex] is [tex]8[/tex].

So,

The difference between the other zero from [tex]3[/tex] should be the same as the difference between [tex]3[/tex] and [tex](-5)[/tex].

i.e.

[tex]a-3=8[/tex]

[tex]a=11[/tex]

Hence the value of its other zero is [tex]11.[/tex]

Okay can you guys help me find which one is the variable. And like what it means for like example x could equal to distance in km

Answers

Answer:

a) 1000+0.05x ≥2200

b) x=24000

Step-by-step explanation:

a) So we know that Nadia for certain gets paid $1000 each month. That is a concrete amount that doesn't change, so the variable (x) would be placed on the 5% she earns from sales. We don't know how much she sells each month because it varies, so that will be represented by the X. Her goal is to raise NO LESS than $2200, which means the amount she earns from sales has to be greater than or equal to $2200.

b) From here just solve the equation for X:

Answers

Answer:

approximately 8.9

Step-by-step explanation:

Regard (3, -2) and (7, 6) as the two acute angle vertices of a right triangle.  The horizontal leg of this triangle has the length (7 - 3) = 4, and the vertical leg 6 - (-2) = 8.  

Apply the Pythagorean Theorem to find the length of the diagonal connecting these two points.  This length is the distance between the two points:

d = √(4² + 8²) = √(16 + 64) = √80 + √16√5 = 4√5, or approximately 8.9

What describes the relationship between a food chain and a food web?4. What would most likely be the result of an invasive species entering an ecosystem?5. Why are humans responsible for many invasive species?6. What are the three main roles of an ecosystem?7. What is the purpose of a decomposer in an ecosystem?An ecosystem is made up of all the living and nonliving things in an area. The living parts include plants, animals and insects. The nonliving parts include water, rocks, soil and sand. Swamps,prairies, oceans and forests are all examples of ecosystems.There are usually many different kinds of life in a single ecosystem. A grassland ecosystem, for example, contains much more than just grass. It includes other plants, mammals, insects and earthworms. It also includes many tiny living things in the soil.Three Roles For Living Things Each living thing in an ecosystem has a role to play. The three main roles are producer, consumer and decomposer. Green plants are producers. They make their own food through a process called photosynthesis. Animals, including humans, are consumers. They eat, or consume, plants or other animals. By Encyclopaedia Britannica,Bacteria and other living things that cause decay are decomposers. Decomposers break down the waste products and dead tissue of plants and animals. They return nutrients to the soil. These nutrients help new plants grow. Producers, consumers and decomposers depend on one another and provide nutrients for one another.This is called a food chain.Feeding Levels A food chain describes the order in which matter and energy move through the feeding levels of an ecosystem. The levels of a food chain are basically the same across all ecosystems. The first level is the producers. After that is the consumers. Sometimes consumers are further divided into primary consumers, secondary consumers and tertiary consumers. The final link in all food chains is the decomposers. The decomposers break down dead organisms and natural waste.The consumers at the top feeding level of a food chain are called top predators. They have no predators hunting and trying to eat them. Instead, their population size is controlled through competition. They have to compete with one another for food and other resources.Energy FlowThe main source of energy in almost all ecosystems is the sun's energy. As energy moves through the ecosystem, much of it is lost at each feeding level. Itescapes as heat. That is the main reason why few food chains have more than five feeding levels. Diagrams called energy pyramids are used to show the flow of energy from one feeding level to the next in a food chain. Most ecosystems have more than one food chain. Food chains overlap. They connect to form a food web.Recycling Nutrients Many nutrients are constantly cycling through an ecosystem. These include water, carbon and nitrogen. A nutrient is something that helps living things grow.Nutrients from soil enter into plant tissues. When consumers eat the plants, the nutrients enter the consumers' tissues. Consumers that are eaten transfer the nutrients on to the predator at the next feeding level. Consumers that are not eaten die and transfer nutrients in their decaying tissues to the decomposers that feed on them. The decomposers recycle these nutrients back into the ecosystem. They transfer the nutrients back into the soil and air, where the nutrients become available to producers.A Delicate Balancean ecosystem's health depends on a delicate balance. This balance must exist between all of the members of the ecosystem, and their surrounding environment. If something disturbs the balance,the ecosystem and all its members might suffer. Natural things that can disturb ecosystems include a changing climate and natural disasters.Human activities that can disturb ecosystems include polluting and clearing land for farms or buildings.Humans also are responsible for many invasive species. An invasive species is a living thing that spreads through an ecosystem where it did not exist before. Invasive species can threaten the plants and animals that originally made up the ecosystem. For example, Burmese pythons were brought to Florida as pets. Some pythons escaped and began reproducing in the wild. Their skill at hunting has decreased the number of wood rats and storks in the area. This upset the balance of the natural ecosystem. please help i dont get it :( A student draws two parabolas on graph paper. Both parabolas cross the x-axis at (4, 0) and (6, 0).
