Answer: "B. 12p^6q^5

Step-by-step explanation:

The given monomial : 6a^2b^8c

Degree of this monomial = Sum of powers of variables=2+8+1= 11

Let's check all the options

A   18t^8

Degree = 8

B 12p^6q^5

Degree = 6+5 =11

C 9a^5b^3c^2

Degree = 5+3+2=10

D 6w^4x^2y^3z^3

Degree =4+2+3+3=12

We can see that only option B has degree 11.

So, the monomial has the same degree as 6a^2b^8c is "B. 12p^6q^5 "

20 % of 2 is equal to<br> A. 20<br> B. 4<br> C. 0.4<br> D. 0.04
zubka84 [21]

Answer: 0.4

Step-by-step explanation: To find 20% of 2, first write 20% as a decimal by moving the decimal point two places to the left to get .20.

Next, the word "of" tells us to multiply so we multiply .20 by 2.

(.20) (2) = 0.4

Therefore, 0.4 is 20% of 40.

Question and answer choices are in the SS attached!!!! Pls help me! ty!
victus00 [196]

Answer:

B

Step-by-step explanation:

It's a right triangle, so the pythagorean theorem will be used a lot.

First, find the side length on the left.

25^2 = 7^2 + y

y = 24

Now, knowing that 7 - 3 = 4 (the smaller side length), I can use this theorem again to find x.

4^2 + 24^2 = x^2

x = \sqrt{592}

Just need to simplify it a little farther...

592 / 16 = 37, so B must be the answer.

The length of a rectangle is 3 cm more than its breadth. If the perimeter of the
schepotkina [342]

Answer:

breadth = 10 cm

length = 13 cm

Step-by-step explanation:

so,

perimeter = 46cm

2(l+b) = 46cm

or, 2(3+b+b) = 46cm ( because l = 3+b)

or, 2(3+2b) = 46cm

or, 6 + 4b = 46cm

or, 4b = 46cm - 6

or, 4b = 40cm

or, b = 40/4 cm

so, b = 10 cm

now,

l = 3cm + b

l = 3 cm + 10cm

= 13cm

Given that ΔABC and ΔA'B'C' are similar right triangles that share the same slope, m, on the coordinate plane. Find the equation
Oksana_A [137]

Answer:

y=\frac{2}{3}x

Step-by-step explanation:

The similar triangles are drawn in the figure attached.

As shown in the figure, the smaller triangle ΔABC, and the larger triangle ΔA'B'C' share the same slope; therefore, the slope of the hypotenuse is the length of the triangle ΔA'B'C' divided by its base:

m=\dfrac{rise}{run} =\dfrac{height}{base}= \dfrac{4}{6}=\dfrac{2}{3}  \\\\ \boxed{m= \frac{2}{3}}

Therefore, the equation of the hypotenuse is

\boxed{y=\dfrac{2}{3} x}
