Answer 1

Answer:

150 degrees

Step-by-step explanation:

The sum of all angles in a pentagon is 540 degrees. So you add the measurements of the 4 you know - 95 + 95 + 100 + 100 = 390. Then you subtract 540 - 390 - 150 degrees for the last angle.

Answer:

15x^2-14x-4

Step-by-step explanation:

(8x^2 * x-7x+2)+(7x^2 -7x-6)

you take out the parentheses

you add the common ones so -7x+-7x= -14x

8x^2 +7x^2 = 15x^2

and 2-6= -4

so in total it's 15x^2-14x-4

Answer: 11x^2 -16x-3

Step-by-step explanation:

Solution:

Your problem → (8x^2-7x+2) + (3x^2-9x-5)

(8x2-7x+2)+(3x2-9x-5)

=8x2-7x+2+3x2-9x-5

=8x2+3x2-7x-9x+2-5

=11x2-16x-3

A cup contains seven red erasers, four
yellow erasers, nine blue erasers, and five
green erasers. Samantha chose an eraser
at random, did not replace it, and chose
another. What is the probability that both
erasers chosen were blue?

Answers

Answer:

17/50

Plzzzz give me Brainliest!  

The probability that both erasers chosen were blue is 3/25.

To find the probability that both erasers chosen were blue, we need to determine the favorable outcomes (choosing two blue erasers) and the total possible outcomes.

There are a total of 25 erasers in the cup: 7 red erasers + 4 yellow erasers + 9 blue erasers + 5 green erasers = 25 erasers.

To calculate the probability, we consider the events of choosing a blue eraser without replacement.

For the first pick, there are 9 blue erasers out of 25 total erasers.

After the first blue eraser is chosen, there are 8 blue erasers remaining out of 24 total erasers.

The probability of choosing a blue eraser on the first pick is 9/25.

The probability of choosing a blue eraser on the second pick, without replacement, is 8/24.

To find the probability of both events occurring (both erasers chosen being blue), we multiply the probabilities together:

(9/25) * (8/24) = 72/600 = 6/50 = 3/25

Therefore, the probability that both erasers chosen were blue is 3/25.

Step-by-step explanation:

A scatterplot has a positive, linear correlation. Which statement is true about the relationship between the x- and y-
values?
o As the x-values increase, the y-values tend to increase.
As the x-values increase, the y-values tend to decrease.
As the x-values decrease, the y-values tend to increase.
O As the x-values decrease, the y-values tend to vary randomly.

Answers

Answer:

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which  is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.

Answer:

a: As the x-values increase, the y-values tend to increase.

Solve for h.
h/10 + 5 = 25
so what’s h ??

Answers

Answer:

h=200

Step-by-step explanation:

h/10+5=25

h/10=20

h=200

h/10 + 5 = 25

Subtract 5 from each side to get h/10 alone.

h/10 + 5 - 5 = 25 - 5

h/10 = 20

Multiply both sides by 10 to get h alone.

h/10 • 10 = 20 • 10

h = 200

h = 200. I hope this helps!

Where these two worlds collide, animals almost never farewell. Highways, where humans speed by large tracts of natural habitat like missiles of doom, are especially dangerous for wild creatures. They can also be deadly, not just for individual animals but for entire species. The Florida panther, for example, has such a low population that each time one is killed on a highway, it is a catastrophic loss.There is hope, however, in a new way of helping animals cross through highway areas unharmed. Wildlife overpasses give animals a way to cross highways without risking their lives. These look and work like bridges but are usually covered with grass and trees that make animals like deer feel welcome. The cars drive through a tunnel under the bridges. Fences along the top edges keep the animals safe.These overpasses also connect habitats, so along with deer, the coyotes who hunt them can cross. This allows both species to have a larger range, which also helps their long-term survival. To the animals in these habitats, the overpasses may be like an extra safety net that helps them survive a drought. The bridges are especially important for animals that migrate. For centuries, animals like elk and buffalo migrated on trails that still, now, lead right up to the edges of major highways. With the help of these bridges, migrating animals can still follow their long-used paths unharmed.In some cases, these overpasses benefit humans directly as well. In these cases, the overpasses are part of green space or parks that people use for cycling, backpacking, or jogging. The overpasses give humans access to areas they may not have been able to see but also provide safety for animals.The next time you are traveling on a highway, keep a lookout for a wildlife passage. With attention to how our lives affect the natural world, we can find clever solutions, like wildlife passages, that help animals and improve our lives, too.Extra! Extra!Not all wildlife accommodations for highways are overpasses. In some cases, certain species are so important that underpasses or underground tunnels are built. In Florida, two such underpasses help turtles, snakes, and alligators that often migrate from one body of water to another. Since these creatures do not have much speed, crossing a highway for them is even more deadly than it is for swift animals like deer. Working as a large funnel, these underpasses usually require a barricade or fence alongside the highway that forces animals toward a tunnel. Aquatic turtles especially benefit from these tunnels as they lay eggs in holes dug in dry ground, away from the lake they live in.what benefit do overpasses and underpasses offer wildlife?A. A view of passing humans and cars B. Access to habitat that helps them survive C. Attention to the need for additional habitatD.
