The buildings of a university are mapped on a coordinate grid with the origin being at library.
The Math building is located at the point (1,5) and the History building is located at (4,9).
How far is it from the Math building to the History building?
units

Answers

Answer:

Step-by-step explanation:

The distance between from Math building to history building is 5 units

What is Distance Formula?

The distance between coordinate P(x , y) and coordinate Q(a , b) is calculated using the distance formula:  d= √(x-a)²+(y-b)²

The Math building is located at the point (1,5)

The History building is located at (4,9).

Using distance formula:

d= √(x-a)²+(y-b)²

  =√(4-1)²+(9-5)²

  = √9+16

  = √25

 = 5 units

Hence, the distance between Math and History building is 5 units.

Remy walked to a friend’s house m miles away at an average rate of 4 mph. The m-mile walk home was at only 3 mph, however. Express as a fraction
a) Time Remy spent walking home.
b)Time Remy spent walking.

(Answer both (a) and (b).

Answers

Answer:

a) m/4 miles per hour

b) 7m/12 miles per hour

Step-by-step explanation:

Mathematically, at any point in time;

Time = distance/speed

The distance here at any point is m mph

a) For the time spent walking home

Time = m/4 miles per hour

b) We add the time walking to the friend’s house and the time that it took to walk home

That would be;

m/4 + m/3 = 7m/12 miles per hour

Answers

Answer:

P = 2(x + 5) + 2(2x - 3)

Step-by-step explanation:

GIven that GR= x+5 and GP= 2x-3 which expression below calculates the perimeter of this gate?

The shape of the gate is rectangular.

Hence, the Perimeter of a rectangle (the gate) = 2L + 2W

Where :

L = GR = x + 5

W = GP = 2x - 3

Hence,the perimeter of the gate is

P = 2(x + 5) + 2(2x - 3)

Step-by-step explanation:

The Pythagorean Theorem states that:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Where c is the hypotenuse, and a and b are the two legs of the right triangle. Substituting in 40 and 42 for a and b, respectively:

[tex]40^{2} +42^{2} =c^{2}[/tex]

Now, we isolate c:

[tex]c= \sqrt{40^{2} +42^{2} }[/tex]

Therefore, c is equal to 58, so the hypotenuse is 58 yards

Joe is saving for a new online video game. He has some money already in his savings, and he can add $2.50 each week. This relationship is shown in the graph. Write an equation and explain what the slope and the y-intercept mean in this situation?

Answers

Answer: Y=2.50x+b

Step-by-step explanation:

Thats not the whole answer, you didnt attach the graph but what you need to do is find the y-intercept and put that into b and theres your equation. The y-intercept(B) represents the initial  money that joe had in his savings the 2.50x part or the slope is the money that he states he can add each week.

Answer:

slope is how much money joe adds to his account savings each week

the y intercept is the money he had before he started waiting

for the equation the slope is $2.50 and the y intercept is where the line hits the y axis but because you don't have a graph I don't know how to help you with this part, maybe someone else can!

it wants us to solve for x and i’m very confused

x= ?

Answers

Answer:

x = 6

Step-by-step explanation:

∡J = ∡K and ∡M = ∡L

because this is an isosceles trapezoid

∡J + ∡M = 180°

because angles at opposite bases are supplementary

then ∡J + ∡M = 180°

∡J = (7x + 2)°

∡M = ∡L = (25x - 14)°

so:

(7x + 2 + 25x - 14)° = 180°

(32x - 12)° = 180°

32x = 180 + 12

32x = 192

x = 6

Answer:

x= 8/9

Step-by-step explanation:

7x + 2 = 25x - 14

-7x         -7x

2 = 18x - 14

+14       +14

16 = 18x

18     18

x=8/9

This is another challenging questionnn yayy All over the world, animal habitats bump up against human development. 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.Read this sentence from the text: In some cases these overpasses benefit humans directly as well.What is the purpose of this line in the essay?(options are below) The writer wants to add a sentence after sentence to provide factual support for the introductory claim and focus the audience on the argument of the passage.
