Answer:

m∠T = 54°

Step-by-step explanation:

The measure of a straight line is 180°. (Linear angles theorem)

So, m∠WMT + 117° = 180°

m∠WMT = 180 - 117 = 63°

The base angles in an isoceles triangle are equal in measure (base angle theorem)

So,

m∠MWT = m∠WMT

m∠MWT = 63°

The sum of angles in a triangle is 180°. (Sum of angles in a triangle theorem) So,

m∠MWT + m∠WTM + m∠WMT = 180°

Substitute the measures we already found.

63 + m∠WTM + 63 = 180

Simplify.

126 + m∠WTM = 180

m∠WTM = 54°

m∠T = 54°

I hope this helps! Feel free to ask any questions!

Answer:

54°

Step-by-step explanation:

First calculate Angle WMT as: 180° - 117° = 63°

And note that Angle WMT = Angle MWT = 63°

Therefore, Angle T = 180° - 63° - 63°

Angle T = 54°

Prompt:
What does it mean to multiply polynomials?
Explain how to multiply (x + 2) (X - 4) as if you're teaching a student a year
younger than you.

Answers

Answer:

We assume before this you have learned how to multiply two monomials and monomial with binomial.

Use the following formula to multiply binomials:

(a + b)(c + d) = ab + ad + bc + bd

Applied to the given expression, we have:

(x + 2)(x - 4), where a = x, b = 2, c = x , d = -4

Expand as indicated above:

(x + 2)(x - 4) =x(x) + x(-4) + 2(x) + 2(-4)

Now simplify

x² - 4x + 2x - 8

Collect like terms, (-4x) and (2x):

x² + (-4x + 2x) - 8 = x² - 2x - 8

This is how you can do same order operations with any binomials.

We can simply use distributive law of grade 1

(a+b)(c+d)=ac+ad+bc+bd

I assume you know multiplication of monomials

So

(x+2)(x-4)x(x-4)+2(x-4)x²-4x+2x-8x²-2x-8

help pls all the questions i dont get it :(​

Answers

Answer:

A. The graph is not proportional, although it has a consistent slope, it does now go through the point of origin or (0,0). The equation of a proportional line is y=kx, so the y-intercept must be at (0,0).

B. Slope is found by  [tex]\frac{rise}{run}[/tex], from 1 point to the next, the y-value (rise) increases by 2 and the x-value (run) increases by 1, [tex]\frac{4}{1} = 4[/tex] giving us a slope of 4.

C. The y-intercept is the lines point of intersection with the y-axis. In the graph, this point is (0,10).

D. y = mx + b is the slope-intercept form where m is the slope and b is the y-intercept, the slope (m) is 4 and the y-intercept (b) is 10. y = 4x + 10

E. The equation is not proportional because the b value is 10 rather than 0.

Answer:

A. The graph is not proportional. I know this because the line doesn't go through the origin (0, 0). B. The slope (m) of the graph is 4. C. The y-intercept is 10. D. The equation in slope-intercept form is y=4x+10. E. The equation is not proportional. I know this because the line began from 10.

Step-by-step explanation:

The graph will be proportional when the line goes through the origin, (0, 0). The equation [tex]m=\frac{y2-x2}{y1-x1}[/tex] is used to solve for the slope (m). Pick any given points from the graph that's on the line to solve for slope (m). (0, 10) and (1, 14) makes it easier to solve for "m".

[tex]m=\frac{14-10}{1-0} =\frac{4}{1} =4[/tex] (4 is the slope)

Substitute x and y with any point given to find the y-intercept:

[tex]14=4(1)+b[/tex]

[tex]14=4+b[/tex]

[tex]-4[/tex]    [tex]-4[/tex]

----------------

[tex]10=b[/tex]

*Note that the y-intercept is always (0, any number)

Example: (0, -24)

Once you know what the slope and the y-intercept are, you'll have the equation set as y=4x+10.

What is a Parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The sum of angles of a parallelogram is 360°

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the parallelogram be represented as ABCD

Now , In a parallelogram, consecutive angles are always supplementary, which means the sum of two consecutive angles is always 180 degrees

This property holds true for all parallelograms

Hence , the consecutive angles are supplementary

Jada was at the state fair from 8:45 am until 11:00 am. How much time did Jada spend at the state fair?

Answers

She spent 1 hour and 15 minutes at the fair, if it’s open at that time.

Answer:

Jada spent 3 hours and 15 minutes at the state fair.

Step-by-step explanation:

She started at 8:45 am and left at 11:00 am.

So 8:45 to 9 is 15 minutes.

So how far away is 9 am to 11 am?

11 - 9 = 3

3 hour difference

But remember to add the 15 minutes from the 8:45 to 9

b)70

Step-by-step explanation:

The sum of the interior angles in a triangle is 180.

a)95+56+a=180        b)40+2b=180

151+a=180                     2b=180-40

a=180-151                      2b=140  /2

a=29                              b=70

Every angle in a circle must add to give 180 so therefore for the first question =
a) 95+56+__ = 180 so the answer would be 29
Isosceles triangles have two identical angles inside that need to be the same.
b) 180-40=140 and to have two identical angles half 140 which gives you a final answer of 70

The Zimmerman Telegram Help me on my homework pls From Enemy to FriendWolves and dogs are closely related. Most scientists believe that dogs ancestors were wolves. Through time, wolves became tame enough to live with humans and help them. The change from wolf to dog was probably a result of careful breeding. Early humans allowed only the friendliest wolf pups to remain near them. This ensured that, over time, the wolves that stayed with groups of humans became tamer and tamer.Wolves were influenced by their relationship with humans. So, they slowly became what we know today as dogs. They became adept at protecting and herding sheep and other animals whereas their ancestors would have made a meal of them. This ability made dogs very useful. However, although they are quite similar, wolves and dogs are also quite different.Wolves are wild animals that live in packs, or groups, and eat only meat. They find their food by hunting. The most common noise they make is a howl. They may also bark, growl, yelp, and whine. All wolves look very much alike, although their colors vary slightly. They are large, slender, powerful animals with long legs and tails. Wolves are quite wary of people; they dont trust them. They attack people only on rare occasions, usually when they are startled.Dogs, on the other hand, are tame. They have been influenced by people for many, many years, which has made them quite different from wolves. For one thing, dogs eat vegetables and grains as well as meat products. They are much more likely to bark than to howl. Their sizes range from gigantic animals that are much larger than wolves to tiny animals that can sit comfortably in a cereal bowl. Large dogs are not only taller than wolves, but they are much heavier, and their appearances can vary as much as their sizes.However, the main difference is found in dogs relationship with humans, whom they usually prefer to be near. The main effect of this is that most dogs are friendly to people. Some show hostility, but almost always only to strangers. Although most dogs are no smarter than wolves, they can certainly be trained more easily. They rarely hunt prey to eat and depend on their owners to supply them with food. This reliance on people just adds to the closeness of the relationship.Wolves and dogs both pant to stay cool. They both can hear and smell very well, and they both can run silently. They even have the same number of teeth: 42. However, no matter how similar wolves and dogs may seem to be, wolves can never be made into a pet. They are also worthless as guard animals because they are shy. Domestic animals, such as cats and small dogs, are in more danger from wolves than humans are, but small children can also be in danger. The Big Bad Wolf may exist only in fairy tales, but real wolves can be as much of a threat, especially if they are not understood. this is total number of genes of every individual in an interbreeding population True or False: There were more people moving to the South for workthan the North need answer. please help Dyami lives x miles from the school.
