for A you should take each plotted point and change the sign of the x values. for example (-1,3) should become (1,3) and (-4,4) should become (4,4)

for B take each point and flip the variables and x's sign. (-1,3) should become (3,1)

for C take every x value and subtract 2. (-1,3) should become (-3,3)

for D take each point and flip the variables and y's sign. (-1,3) should become (-3,-1)

An isosceles triangle has an angle that measures 126°. Which other angles could be in that isosceles triangle? Choose all that apply.

27°
69°
127°
17°

Answers

Answer:

Step-by-step explanation:

Since triangles have only 180 degrees in a triangle we can rule out the option that 126 degrees is another angle. So subtract 126 from 180 and you get 54. Then you divide 54 by 2 and get 27.

B. (x - 4, y + 8)
C. (x – 8, y + 4)
D. (8x, 4y)

Answers

A. (X + 8, y - 4) hope this helps pls make me brainlyest

The correct answer is A. (x + 8, y - 4)

This is the correct answer because when going right on the x axis, means that you are adding or that it is positive. When going left on the x axis, means you are subtracting, or it is negative.

On the y axis, when going up, you are adding or it is positive. So when you are going down, means you are subtracting or it is negative.

I hope that this helps.

B=base area, to get B use the equation πr².

H= height

Side A= 12

Side B= 10

Side C= 10

For the height we will use 34, or the height of the prism.

48*34 equals 1632, And your volume is 1632.

A storage box has a volume of 56 cubic inches, and the base of the box is 4 inches by 4 inches.

What is the height of the box?

Answers

The height of the box is 3.5in or 3 1/2in

Ok, so first we need the equation. So we know that v=b*w*h. We know that the base is 4 inches and the width is 4 inches as well. So we get the equation v=4*4*h. The volume is also given so the equation changes to 56=4*4*h. So first we multiply the numbers we have to get 56=16*h. Then we divide 16 on both sides. 56/16 is 3.5. We end up with 3.5=h. So the answer is 3.5 inches. You can also put this back in to make sure it is right. To 56=4*4*3.5 is true. So therefore, the answer is 3.5 inches.

Match each expression in column A with an equivalent expression from column B.

Column A

12(r + t) − 6(r + t) + 4(r + t) − 2(r + t)

Column B

8(r − t)
8(r + t)
8r + 7t

12r + t − 4r + 6t

Answers

Answer:

see answers below to match them

Step-by-step explanation:

12r + t - 4r + 6t

=12r - 4r + t + 6t

=8r + 7t

(12r+2t) - (4r+10t)

=12r + 2t - 4r - 10t

=8r - 8t

=8(r-t)

12(r+t)-6(r+t)+4(r+t)-2(r+t)

=(12-6+4-2)(r+t)

=8(r+t)

Use the Pythagorean theorem to solve: [tex]a^2+b^2=c^2[/tex]

[tex](6.3)^2+b^2=(15.4)^2[/tex] <-- plug in a and c values into equation

[tex]39.69+b^2=237.16[/tex] <-- take out parentheses

[tex]b^2=197.47[/tex] <-- subtract 39.69 from both sides

[tex]b=14.0524019299[/tex] <-- take the square root of 197.47

An Indian anthropologist, Chandra Thapar, made a study of foreign cultures which had customs similar to those of his native land. One culture in particular fascinated him because it reveres one animal as sacred, much as the people in India revere the cow. The tribe Dr. Thapar studied is called the Asu and is found on the North American continent north of the Tarahumara of Mexico. Though it seems to be a highly developed society of its type, it has an overwhelming preoccupation with the care and feeding of the rac - an animal much like a bull in size, strength and temperament. In the Asu tribe, it is almost a social obligation to own at least one if not more racs. Anyone not possessing at least one is held in low esteem by the community because he is too poor to maintain one of the beasts properly. Some members of the tribe, to display their wealth and prestige, even own herds of racs. Unfortunately the rac breed is not very healthy and usually does not live more than five to seven years. Each family invests large sums of money each year to keep its rac healthy and shod, for it has a tendency to throw its shoes often. There are rac specialists in each community, perhaps more than one if the community is particularly wealthy. These specialists, however due to the long period of ritual training they must undergo and to the difficulty of obtaining the right selection of charms to treat the rac, demand costly offerings whenever a tribesman must treat his ailing rac. At the age of sixteen in many Asu communities, many youths undergo a puberty rite in which the rac figures prominently. The youth must petition a high priest in a grand temple. He is then initiated into the ceremonies that surround the care of the rac and is permitted to keep a rac. Although the rac may be used as a beast of burden, it has many habits which would be considered by other cultures as detrimental to the life of the society. In the first place the rac breed is increasing at a very rapid rate and the Asu tribesmen have given no thought to curbinanswer this question pleaseeee 1)What is the Theme (An underlying message about life or human nature that the writer wants the reader to understand) of this work?
