A 46
B 3
C) 305
D 133

Answers

Answer:

probably C

Step-by-step explanation:

The question can be written as:

8 * 1.032^n = 140 000, this can be rearranged to

140 000/8 = 17500 = 1.032^n

now we need to find n, we could do this manually with a calculator, but an easier method is to use [tex]\log_x(y)[/tex]

example of log

2^3 = 8

log2 (8) = 3

log1.032 (17500) = 310.17

What is the two fifths of the collection pilers, hammers, wrenches, saws.​

Answers

Answer:

Pliers

Step-by-step explanation:

From the picture attached,

Number of pliers = 4

Number of hammers = 2

Number of wrenches = 2

Number of saws = 2

Total collection of tools = 4 + 2 + 2 + 2 = 10

Since, two fifth means,

[tex]\frac{2}{5}=\frac{2\times 2}{5\times 2}[/tex]

[tex]\frac{2}{5}=\frac{4}{10}[/tex]

That means tool with 4 counts out of total 10 tools will be the answer.

And the answer is pliers.

A trampoline park costs $12 for the first hour and $6 for each additional hour. Flynn pays $30 at the trampoline park. Select the equation that represents the given situation and find the number of additional hours Flynn stays at the trampoline park after the first hour.
A. 12x + 6 = 30; 3 hours
B. 6x + 12 = 30; 3 hours
C. 6x + 12 = 30; 2 hours
D. 12x + 6 = 30; 2 hours

Answers

Answer is B. 12 dollers for 'admission' and then you have 6 per hour of time

The equation that represents the given situation is 12 + 6x = 30.

The number of additional hours is 3.

Option B is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

A trampoline park costs $12 for the first hour and $6 for each additional hour.

Amount paid at the park = $30

Now,

12 + 6x = 30

x is the number of hours.

Solve for x.

12 + 6x = 30

6x = 30 - 12

6x = 18

x = 3

Thus,

The equation is 12 + 6x = 30.

The number of hours is 3.

p - q - x(q - p) ← distribute parenthesis by - x

= p - q - qx + px ← rearrange terms in p and terms in q

Will a pair of 6 feet 11 inch long skis fit in a wardrobe that is 3 feet long, 2 feet wide and 6 feet high?

Answers

Answer:

Step-by-step explanation:

Length of a pair of skis = 6 feet 11 inches

Maximum length of a the skis that can be fitted in a wardrobe is along the diagonal of the wardrobe.

From the picture attached,

BC² = 3² + 2² [By Pythagoras theorem]

BC = √(13)

By applying Pythagoras theorem in ΔABC,

AB² = AC² + BC²

AB² = 6² + (√13)²

       = 36 + 13

AB = √49

Ab = 7 feet

Since, "diagonal length of the wardrobe is more than the length of skis,

skis can be fitted"

What is the slope of the line that passes through the points (-2, 8)(−2,8) and (-22, 8) ?(−22,8)? Write your answer in simplest form.

Answers

Answer:

           0

Step-by-step explanation:

The slope of the line passing through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(-2, 8)   ⇒   x₁ = -2,  y₁ = 8

(-22, 8)   ⇒     x₂ = -22,  y₂ = 8

So, the slope:

                     [tex]m=\dfrac{8-8}{-22-(-2)}=\dfrac{0}{-20}=0[/tex]

use Pythagorean theorem

to simplify down to find the opposite angle

The sum of the squared lengths of the other two sides of a right triangle equals the square of the hypotenuse's length, which can be defined as follows:

Need help asap, please.The melting of the polar ice caps. There are millions of polar ice caps in the world and there are Millions of wildlife and organisms living on them. They can grow enormous up to 50,000 square kilometers. They take up 14.6 million km of the earth. They are getting smaller day by day and night by night. They are melting. At the rate that it is melting by 2035, the polar ice caps will be gone and all coastal cities will be flooded and destroyed. The polar ice caps would have been around for millions of years in the world's oldest architecture. There are so many animals that live under polar ice caps. Some animals are brown bears, polar bears, arctic foxes and wolves, whales, birds, fish, krill, penguins, etc. There are so many animals that stay alive on and under the ice caps. The environment is perfect for the animals and we are ruining it for those animals. The ecosystem under the icecaps is amazing. It is a great place for fish, krill, and aquatic organisms. It is a safe spot for small animals because the animals on top of the ice caps won't go into the water unless they have to because there are bigger predators in the water like leopard seals, killer whales, and big fish. More and more animals die every day because the ice caps are getting smaller and smaller There are big rivers that are flowing into the ocean from the ice caps. These Rivers are bad because they flood everywhere and it ruins animals' homes and shelters. It is also good because now the animals can drink and not have to worry about getting eaten by a leopard seal or a killer whale, but now the animals will overpopulate and be indeed for more food. Every day billions of tons of ice melt, and the ice caps have 90% of the freshwater on earth. The ice caps are breaking apart and big chunks of them are starting to fall into the water which isn't good because they are raising the sea level. They are not good to have in our ocean because the broken pieces take a long time to melt and those big chunks float and also hit boats or other ice caps that break apart them. It is not good to have thousands of ice caps scattered around the take up The only way we can slow down the process of melting is if we stop burning so much energy and use solar or electric power to do our daily tasks driving places and burning trash. Electric cars are great for the world but we need to find a better power source because it is hard to get so much electrical energy from the earth. Solar power is another way millions of people use solar power on their roofs of their houses so that the power that they receive from the sun is subtracted from their electrical bill. It is a great power source but it is not as effective because it requires an extremely strong energy source to power them. Luckily we have the sun and that helps out a bunch. Climate change also is a huge factor in the melting of the polar ice caps. When the climate changes everything has to adjust to that climate and the ice caps can't. Over the past 100 years, the climate has changed by 1.0o F. That is a lot. Even though it seems so small for the climate to change it takes a lot of burning fuel and waste. We cut and burn so much wood, metal, biofuel, trash, etc. We all do it even if you think you recycle some of it still is burned so try to reuse your trash as much as possible. When we reuse something it proves that something can be used twice rather than throwing it out without seeing what you could do with it. You can reuse anything like plastic water bottles, home depot buckets, plastic straws, fruit cups, and much more. Everything helps the environment and you should make a difference by going out of your way to do things for the environment. Picking up trash on the road, sidewalk, forest, buildings, or anywhere you can think of. When you do a small act of kindness you can feel better. You also help the ice caps from melting faster.

Fossils can be molds, or imprints left from something buried. The actual structure decomposes, but the shape is left behind. A shell imprint in a rock is an example. Fossils can also be casts. Casts are molds that fill in over time. They show a three-dimensional shape of the structure that used to be there. A walnut mold that fills in with minerals is an example. Plants and animals can also be preserved when they are trapped in certain circumstances. Tar, ice and amber have all trapped animals for thousands of years. Amber comes from tree resin, or sap, which hardens. Insects from long ago have been found preserved in it. In California, tar pits preserved many animals, including a mastodon and a saber-toothed cat. What is the difference between a mold and a cast? A Molds are body fossils, and casts are trace fossils. B A mold is an imprint, and a cast is a filled-in imprint. C Molds are made of amber, and casts are made of tar. D Molds come from plants, and casts come from animals.
