Please help on this practice paper my parents couldn’t solve this either
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: 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

how to solve a one step equation??
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.

John 3 miles on Monday, 2 miles on Tuesday. He ran 4 more miles on Wednesday then he did on Monday. How many miles did John run Monday through Wednesday?
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]
the volume of a cube depends on the length of its sides. The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(4) = 64?
Answer options in the picture.
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

Imagine that you and your friends are going to a drive-in movie. The screen, which is 40 feet high, is elevated height 60 feet on posts. If you park your car 77 feet from the screen, at what angle will you be watching the movie?
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
What's the value of x? (Hint: it's not 7) and please explain
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

What is the period of the function f(x) shown in the graph?
Answer:
[tex]\dfrac{\pi }{2}[/tex]
Step-by-step explanation:
The period of the function is from one peak to the next (or from one trough to the next).
[tex]\sf \implies period=\dfrac{\pi }{2}[/tex]
**see attached for the measurement of the period for this function**
5b - 5 - 126 - 7
I need steps please and thank you
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

Which statement best explains the value of 12-(-4)??
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. :)
∠A and ∠B are supplementary. The measure of ∠A is 34°.
What is the measure of ∠B?
Enter your answer in the box.
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°
