What is 2.5 - 1.4

Answer:

2x²-8 if it doesnt give you x=   if it gives you an x= then comment it and ill work it out.

Step-by-step explanation:

it was pretty simple

Answer:

[tex]64x^{12}[/tex]

Step-by-step explanation:

We have to use the law of indices for finding the equivalent expression.

[tex](8x^{5})^{2} = 64x^{10}[/tex]  We square 8, which is 64 and multiply the two powers.

[tex](x^{4})^{\frac{1}{2}} = x^{2}[/tex]  We multiply the 2 powers giving us, [tex]\frac{4}{2}[/tex], which simplifies to 2.

[tex]64x^{10}[/tex] × [tex]x^{2}[/tex] = [tex]64x^{12}[/tex]  This is the answer as we multiply the two indices together.

I hope this helps!! ^-^

Answer:

64x¹²

Step-by-step explanation:

(8x^5)^2 × (x^4)^1/2

64x^10 × (x^4)^1\2

64x^10 × x^2

Calculate:

64x^12

Answer:

Hence, 5174.4litres of water can be stored in the drum.

Hope it helps..

Have a great day :)

Answer:

volume is equal to πr²h

ie

3.14 × 28² × 210

=516,969.6

divide the result by 1000

516.969litres

Answer: 1/10

Step-by-step explanation:

1: Let’s take out the “DO NOT REPLACE IT.” It can make the whole thing seem harder. Rather, here is this. “There are five marbles in a bag, 3/5 are green and 2/5 are yellow. You DRAW TWO MARBLES. What is the chance of you drawing two yellow marbles?”

2 : Now let’s look at some important information.

100% of marbles= 5 marbles.

60% of marbles= the three green marbles.

40% of marbles= the two yellow ones.

Picking 2 of the 5 marbles will mean taking 40% of the marbles out of the bag.

Simplify: Now, to make it easier, the question is this. what is the chances of the 40% being the same color, Specifically yellow.

3: Let me explain. There are two yellow marbles, you pick out two. That is a one out of five chance of you getting ONE yellow marble the first time. That is 1/5. picking two at the same time results in a 2/5 chance.

4: if you pick twice it would be 1/10 chance.

Answer:

a≥-5/2

Step-by-step explanation:

Step-by-step explanation:

To help you, Remeber the SOHCAHTOA rule

For 3,The side that is opposite of c is 28 and the hypotenuse (which is the longest side of the triangle) is 35. So the answer is 28/35. or 4/5.

For 6, 32 is opposite of A and 40 is the hypotenuse so

32/40 or 4/5 is our answer.

For 7, 24 is opposite of Z and 40 is the hypotenuse so

24/40 or 3/5 is the answer.

For 8, 14 is opposite of Angle C and 50 is our hypotenuse so

14/50=7/25 is our answer

COS

To find cos it is adjacent/hypotenuse

For 2 the adjacent side to C is 16 and the hypotenuse is 34. so our answer is 16/34 or 8/17.

For 5, the adjacent side is 30 and the hypotenuse is 34 so our answer is 30/34 or 15/17

For 9, the adjacent side is 24 and hypotenuse is 30 so our answer is 24/30 or 5/6.

TAN

TO FIND TAN, it is Opposite/Adjacent

4, the opposite side is 32 and the adjacent is 24 so our answer is 32/24 or 4/3.

10, the opposite side is 27 and the adjacent is 36 so our answer is 27/36 or 3/4

Answer:

Answer:

64 degrees

Step-by-step explanation:

Combining the 90 degrees, x degrees, and 26 degrees creates a flat angle or 180 degrees

so first, combine 90 and 26 degrees

90+26= 116

then subtract 116 from 180

180-116= 64 degrees

Answer:

C

Step-by-step explanation:

Hello There!

The height of the water starts at 3 feet and its receding at a rate of .75 feet an hour

receding means to move farther away from previous position

so the equation would be

3-.75t

or

-.75t + 3

So we can conclude that the answer is C

Answer:
