How many feet are shorter than 20 centimeters

Express the quotient as a fraction in simplest form

Artemon [7]

Answer:

-5/6

Step-by-step explanation:

A great way to divide fractions is to use the "leave it, change it, flip it" method. You leave the first fraction as it is, change the division sign to a multiplication sign, and flip the second fraction so you get the reciprocal. Like this:

-5/7 ÷ 6/7

-5/7 x 6/7

-5/7 x 7/6

Then you multiply through. First -5 x 7, -35, and then 7 x 6, 42, to get -35/42. Because both of these are divisible by 7, we can simplify to get -5/6.

Given f(x) = 6x^4 – 10x^3 + 40x – 50, find f(2)

ASHA 777 [7]

F(x)=6x^4-10x^3+40x-50, plug 2 in for x
f(2)=6(2)^4-10(3)^3+40(2)-50
f(2)=12^4-30^3+80-50
f(2)=20735-27,000+80-50
f(2)=-6,235

Pleaseeee helppp !!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!

Since triangle STU and TVW are similar angle VWT and SUW are equal, this means:
106-5x=7x-14
(106)+(14)=(7x)+(5x)
120=(12x)
10=(x)
Angle VWT=106-5x=106-(5)(10)=56

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x

Virty [35]

Answer:

A Is congruent to B and B Is congruent to C

Step-by-step explanation:

Let's look at the answer choices:

A: "A Is congruent to B and B Is congruent to C"

Well, clearly, if A ≅ B and B ≅ C, then by the transitive property, we can say that A ≅ C. So, A is very likely correct.

B: "A Is congruent to A, B Is congruent to B, C Is congruent to C"

Just because A is congruent to itself (and same with B and C) doesn't necessarily mean that they're congruent to each other. So, B is wrong.

C: "Each triangle is a right triangle."

Again, there are so many right triangles out there with different dimensions. For example, there are some with sides 3, 4, and 5, and others with sides 5, 12, and 13. They are not congruent, however. So, rule out C.

D: "Each triangle is an isosceles triangle."

This is just like choice C since there are so many variations of isosceles triangles. So D is wrong.

The answer is thus A.

What is the total surface area A.640 B.264 C.320 D.525

kykrilka [37]

Answer:

B. 264

Step-by-step explanation:

Although the figure may look odd, This is just a square pyramid on it's side.

So, to find the surface area, we need to find the area of the base and the area of the faces and add them together.

To find the area of the base:

Since the base is a square, all we have to do is multiply 8 by itself.

8 * 8 = 64

The area of the base is 12.5 in^2

To find the area of the faces:

Since the faces are triangles, we have to multiply the length by the height and divide by 2.

8 * 12.5 = 100

100/2 = 50

The area of one face is 50 in^2

To find the surface area:

Add the area of the base to the area of all 4 sides.

64 + 4(50)

64 + 200 = 264

The surface area of the pyramid is B. 264 in.^2
