help plz asap help me plz Angles of Triangles

Answer:

Triangle D

Step-by-step explanation:

Triangle A is an isoceles because two of the sides are equal in length.

Triangle B is a right isoceles triangle because two of the sides are equal in length and there is a right angle.

Triangle C is an isoceles because two of the sides are equal in length.

Triangle D is a scalene triangle becasue none of its sides are the same length.

Answer:

r≈12.89

Step-by-step explanation:

Using the formula

C=2πr

Solving for r

r=C

2π=81

2·π≈12.89155

Area= LxW ( leangth x width)

- hope this helps :)

Answer:

X= 41

Y= 90

Z= 41

Step-by-step explanation:

X=Z

Y+49=139

Z+Y+49=180

X+139=180

139+49+X+Z+Y=180

These we know because of the placement of the angles.

Using this information, we can solve this in numerous ways. I'm going to solve it using one of them. Making both sides equal to 180 and then checking my work by adding all of the numbers I get together to make sure that they equal 360.

X+139=180

X=41

X=Z.

49+Z+Y=180

49+41+Y=180

90+Y=180

Y=90

Thus,

X= 41

Y= 90

Z= 41

To check, let's add them all together.

41+90+41+139+49=

360

This is correct!

Answer:

12.5

Step-by-step explanation:

To find the volume you do L*H*W and I got.

Answer:

12.5

Step-by-step explanation:

to get it you have to multiply the length times the width times the height.

this method works for almost every 3D shape.

Hope this helps!!!

Answer:

28 i think then 15 if im work sorry ill rework it out in a min

Answer:

Hi! Im not sure about the other parts- But i know how to solve for the median!

Step-by-step explanation:

Ok to start off this is your data set.

64 53 60 60 56 58 51 55 60

Then after you place all these numbers in order from least to greatest.

51 53 55 56 58 60 60 60 54

Then you cross them out from side to side till you have the middle number or two numbers in the middle.

58,

So your median is 58!

(I know how to solve for the other ones but i think this is part a)

So i think its this-

Minimum: 51

Median : 53

Maximum: 64

First quartile: 55

Thirf Quartile: 60

( To solve for quartile tiles just say "I crossed out the numbers on each side starting from the median to the minimuk for the first quartile and then the Maximum for the Third quartile.)

I hope dis helped :> Bye!!

Answer:

The answer is $420 dollars

Step-by-step explanation:

you times 560 by 25%

that comes to a total of 140/

Ms. Dawson's class raised 25 percent more so you would have to subtract 140 from 560

560-140=420

420 is how much Mr. Casey's class raised

Answer:

The third one

Step-by-step explanation:

If you look at the graph you see that the relationship between the points is linear positive correlation

Therefore c is your answer :)

Answer:

A) Because A and E are perpendicular therefore making B 90 degrees. D same for DBC

B) Same as A. for A

C) because they are perpendicular to eachother

D) Because they are the same angle they are equal to eachother

E) We assume that they are both 45 degrees thus making them equal to eachother

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

Answer:g is greater than or equal to 6g + 18/5, or g >_ 6g + 18/5

Step-by-step explanation: 5G- 2 <_ 6g + 16

Add 2 to the 16. 5g <_ 6g + 18.

Divide 5 to both sides. g >_ 6g + 18/5

Answer:

2/5−3/5+/10

Step-by-step explanation:

Answer:

1) 147

2) 87[tex]m^{2}[/tex]  

Step-by-step explanation:

1) Area of triangle = × base length × height

= [tex]\frac{1}{2}[/tex] × 14 × 10

= 70 [tex]m^{2}[/tex]

Area of a semicircle = [tex]\frac{\pi r^{2} }{2}[/tex] ( r is the radius)

Radius = half of diameter = [tex]\frac{14}{2}[/tex] = 7m

Area of semicircle = [tex]\frac{\pi 7^{2} }{2} = \frac{\pi49 }{2}[/tex]

= 77[tex]m^{2}[/tex] ( Nearest whole number )

Total area = 77 + 70 = 147[tex]m^{2}[/tex]

2) Divide the shape into 2 rectangles

Area of a rectangle = length × width

Rectangle 1 = 7 × ( 3+3+5 )

= 7 × 11 = 77[tex]m^{2}[/tex]

Rectangle 2 = 2 × 5

= 10[tex]m^{2}[/tex]

Total Area = 77 + 10 = 87[tex]m^{2}[/tex]

Answer:

1) 147

2) 87

Step-by-step explanation:

Answer:

The answer is 379.17 m2

Step-by-step explanation:

First you get the area of the triangle which is A = 1/2 x base x height, then you get the area of the semi circle which is A = 3.14 x r to the power of 2 divided by 2, once you get both answers, you add them up to get your finale answer.

Correct me if I'm wrong, please.

Answer:

she will be able to repaint 7 bookcases

Answer:

I believe it is A) 3.

I believe it is A) because 5 1/4 multiplied by 3/4 is 3.9, and you can't paint 3.9 bookcases, so the answer is 3.
