Which statement explains why the value of [2.4] is 2 but the value of [-2.4] is –3? because 2 is the greatest integer not greater than 2.4, and –3 is the greatest integer not greater than –2.4 because 2.4 rounds to 2, and –2.4 rounds to –3 because 2.4 is positive, and –2.4 is negative because 2 is the least integer greater than 2.4, and –3 is the least integer greater than –2.4

We are given that ,

[tex]{:\implies \quad \sf \dfrac{12+\sqrt{128}}{1-\sqrt{2}}=a+b\sqrt{2}}[/tex]

Consider LHS;

[tex]{:\implies \quad \sf \dfrac{12+\sqrt{128}}{1-\sqrt{2}}}[/tex]

Can be further written as ;

[tex]{:\implies \quad \sf \dfrac{12+8\sqrt{2}}{1-\sqrt{2}}}[/tex]

Rationalizing the denominator we have ;

[tex]{:\implies \quad \sf \dfrac{12+8\sqrt{2}}{1-\sqrt{2}}\times \dfrac{1+\sqrt{2}}{1+\sqrt{2}}}[/tex]

[tex]{:\implies \quad \sf \dfrac{(12+8\sqrt{2})(1+\sqrt{2})}{(1-\sqrt{2})(1+\sqrt{2})}}[/tex]

[tex]{:\implies \quad \sf \dfrac{12(1+\sqrt{2})+8\sqrt{2}(1+\sqrt{2})}{1-2}}[/tex]

[tex]{:\implies \quad \sf \dfrac{12+12\sqrt{2}+8\sqrt{2}+16}{-1}}[/tex]

[tex]{:\implies \quad \sf \dfrac{28+20\sqrt{2}}{-1}}[/tex]

[tex]{:\implies \quad \sf -28-20\sqrt{2}}[/tex]

Hence, we can conclude that ;

Answer: John ran 10 miles through Monday and Wednesday.

Step-by-step explanation: He ran for miles on 4 but 4 more than Monday and he ran 3 miles on Monday, so you add 4 + 3 which = 7 then you add 3 to 7 because he ran 3 miles on Monday then you get 10.

Answer:  28 degrees.

Step-by-step explanation:

See the attached image. 1.2.3 is just seperate angles to help see more details.

Answer:

28°

Step-by-step explanation:

[tex]m\angle UVI +m\angle IVW =m\angle UVW[/tex]

(By angle sum postulate)

[tex]\implies (3x+7)\degree +(12x+6)\degree =118\degree[/tex]

[tex]\implies (15x+13)\degree =118\degree[/tex]

[tex]\implies 15x+13 =118[/tex]

[tex]\implies 15x =118-13[/tex]

[tex]\implies 15x =105[/tex]

[tex]\implies x =\frac{105}{15}[/tex]

[tex]\implies x =7[/tex]

[tex]m\angle UVI =(3x+7)\degree[/tex]

[tex]\implies m\angle UVI =(3*7+7)\degree[/tex]

[tex]\implies m\angle UVI =28\degree[/tex]

Answer:

5b - 138

Step-by-step explanation:

Alright let's break it down.

First, you can see that each constant (5,126,7) have negatives in front of them. SO you are going to subtract each one of them.

When subtracting negatives it's basically just adding them together. How to do it is simply adding:

5 + 126 + 7

Then you get 138.

BUT, it was negative numbers. So it's actually -138.

Then bring back the 5b and your answer is:

5b - 138

Mark brainliest if you can :D

Answer:

16................

Step-by-step explanation:

Above

Answer:

The answer is 16.

Step-by-step explanation:

Negatives can be tricky, but once you get the hang of it, it will be much easier! The rule to remember here is:

"Anything 'minus a negative' just means plus, because the negatives cancel each other out."

a. For example, 4 -(-1) is the same thing as 4+1, which equals 5.

b. In this problem, 12-(-4) is the same thing as 12+4, which equals 16.

I hope this helps! Feel free to give me Brainliest if you feel this helped. :)

Answer:

14.48º

Step-by-step explanation:

tan^-1(100/77) = 52.403...

tan^-1(60/77) = 37.926...

52.403 - 37.926 = 14.477

Answer:

B. A cube with side lengths of 4ft has a volume of 64 cubic feet.

Step-by-step explanation:

The best interpretation of the function is that a cube with a side length of 4ft has a volume of 64ft³;

    Function;

           v(s) = s³

s is the side of the cube;

   Now, if we input 4, the cube is 64

A function simply relates a set to another one.

So, answer choice B is the right one

Answer146°

Step-by-step explanation:The supplement of 34° 34 ° is the angle that when added to 34° 34 ° forms a straight angle (180° 180 °). 180°− 34° 180 ° - 34 ° Subtract 34 34 from 180 180.

Supplementary angles have sum 180°

[tex]\\ \sf\longmapsto x+34=180°[/tex]

[tex]\\ \sf\longmapsto x=146[/tex]

Answer:

A. The rate Aaron travels with the current

Step-by-step explanation:

Distance travelled = 3 mph in still water(downstream)

Time it takes for him to travel with the current = 12 / (3+x)

Where,

x = rate of the current

Denominator, 3 + x = The rate Aaron travels with the current

Therefore, the correct answer is

A. The rate Aaron travels with the current

Answer:

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

thats my answer

Answer:

thee correct  answer is c not d

Step-by-step explanation:

Hey there!

4x + 7 + 35 = 90°

4x + 42 = 90°

SUBTRACT 42 to BOTH SIDES

4x + 42 - 42 = 90 - 42

CANCEL out: 42 - 42 because it give you 0.

KEEP: 90 - 42 because it help solve for the x-value.

NEW EQUATION: 4x = 90 - 42

SIMPLIFY IT!
4x = 48°

DIVIDE 4 to BOTH SIDES

4x/4 = 48/4

CANCEL out: 4/4 because it give you 1

KEEP: 48/4 because it give you the x-value

NEW EQUATION: x = 48/4

SIMPLIFY IT!

x = 12

Therefore, your answer is: x = 12

Good luck on your assignment & enjoy your day!

Answer: 25 feet

Step-by-step explanation:

If you place a 37 foot ladder against the top of a 12 food building, since 37 is greater than 12 the ladder will keep going past the building.

37-12=25

the ladder will be 25 feet from the bottom of the building
