Answer:
1600=50x+100(thats the equation) ACTUAL ANSWER: X=30
Step-by-step explanation:
The inequality represents all possible values of x, which will be 1600=50x+100.
What is linear inequality?Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.
The greatest weight a moving truck can carry = is 1,600 pounds
Weight of the piano = 400 pounds
Weight of box = 50 pounds
The inequality represents all possible values of x will be;
1600 = 50x+100
Hence the inequality represents all possible values of x, the number of these boxes that can be loaded into the moving truck will be 1600=50x+100.

Billy dove off a cliff into the water. The cliff was 15 ft. above sea level. After diving into the water, he swam 5 ft. below the opposite elevation of the cliff and found a golden ring. At what elevation did he find the golden ring?
Answer:
Billy found the ring at -20 ft
Step-by-step explanation:
He started at 15 ft
He dove off the cliff, then swam 5 feet under the opposite of the cliff's elevation
The opposite of the cliff's elevation would be -15, and if he swam five feet under that, it would be -15 + -5 = -20
So, Billy found the ring at -20 ft

Write the STANDARD FORM of the equation of each line given the Slope and y-intercept.
1) Slope = 8, y-intercept = 3
2) Slope= -2/3, y-intercept = 1
Answer: See below
Step-by-step explanation:
The basic form of an equation of a straight line in slope intercept form is y=mx+b, where m is the slope and b the y intercept (the value of y when x=0)
1) Slope = 8, y-intercept = 3
y=mx+b: y = bx + 3
2) Slope= -2/3, y-intercept = 1
y=mx+b: y = -(2/3)x + 1

A 14.5-gallon gasoline tank is $\frac{3}{4}$
full. How many gallons will it take to fill the tank? Write your answer as a mixed number.
The number of gallons it take to fill the tank is 3.625 gallon.
Given that, a 14.5-gallon gasoline tank is 3/4 full.
Let the number of gallons it take to fill the tank is x.
Now, the number of gallons of gasoline tank = 14.5×3/4
= 14.5×0.75
= 10.875
Here, 10.875+x=14.5
x=14.5-10.875
x=3.625
Therefore, the number of gallons it take to fill the tank is 3.625 gallon.

Answer:
w = 63
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 interior angles.
w + 28 is an exterior angle of the triangle , then
w - 2 + w - 33 = w + 28 , that is
2w - 35 = w + 28 ( subtract w from both sides )
w - 35 = 28 ( add 35 to both sides )
w = 63

Rewrite the limand as
[tex]\dfrac{\tan^2(x)}{1 - \cos(x)} = \dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))}[/tex]
Multiply the numerator and denominator by 1 + cos(x). Then
[tex]\dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))} \cdot \dfrac{1+\cos(x)}{1+\cos(x)} = \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)(1 - \cos^2(x))} \\\\= \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)\sin^2(x)} \\\\ = \dfrac{1 + \cos(x)}{\cos^2(x)}[/tex]
As x goes to 0, the limand goes to (1 + 1)/1² = 2.
We are given with a limit :-
[tex]{\quad \blacktriangleright \blacktriangleright \blacktriangleright {\displaystyle \sf \lim_{x\to 0}\dfrac{\tan^{2}(x)}{1-\cos (x)}}}[/tex]
We know that ;
[tex]{\boxed{\bf \dfrac{\sin (\theta)}{\cos (\theta)}=\tan (\theta)}}[/tex]Using this , the above limit can be written as ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)}{\cos^{2}(x)\{1-\cos (x)\}}}[/tex]
Multiplying and dividing both numerator and denominator by [tex]{\sf 1+\cos (x)}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos (x)\}\{1+\cos (x)\}}}[/tex]
We knows a identity that is
[tex]{\boxed{\bf a^{2}-b^{2}=(a+b)(a-b)}}[/tex]Using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos^{2}(x)\}}}[/tex]
We knows another Trigonometric identity i.e ;
[tex]{\boxed{\bf 1-\cos^{2}(\theta)=\sin^{2}(\theta)}}[/tex]Now , using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\cancel{\sin^{2}(x)}\{1+\cos (x)\}}{\cos^{2}(x)\cancel{\sin^{2}(x)}}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{1+\cos (x)}{\cos^{2}(x)}}[/tex]
Putting the limit we have ;
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+\cos (0)}{\cos^{2}(0)}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+1}{1^{2}} \quad \qquad \{\because \cos (0)=1\}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{2}{1}}[/tex]

BRAINLIEST 3/5(x−710)=−314
Answer: x = 560/3
Step-by-step explanation:
First! We are going to be using the PEMDAS method! If you have any questions about this method please go ahead and ask below! The first step in our equation is the P - parenthesis, so we are going to multiply [tex]\frac{3}{5}[/tex] to everything inside of the parenthesis (x and -710)!
[tex]\frac{3}{5} (x -710) = -314[/tex]
[tex]\frac{3}{5}x+(\frac{3}{5}*-710)=-314[/tex]
[tex]\frac{3}{5}x -426 = -314[/tex]
Now, we are going to add 426 to both sides of the equation, to single out the "x" variable!
[tex]\frac{3}{5}x= 112[/tex]
Finally, let's multiply both sides by [tex]\frac{5}{3}[/tex] to cancel out the [tex]\frac{3}{5}[/tex] fractions, to get the "x" variable alone.
[tex]x=\frac{560}{3}[/tex]

determine the zeros of the function f(x) = 2(x – 6)^2 – 4
Answer:
x = 6 ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the zeros equate f(x) to zero , that is
2(x - 6)² - 4 = 0 ( add 4 to both sides )
2(x - 6)² = 4 ( divide both sides by 2 )
(x - 6)² = 2 ( take square root of both sides )
x - 6 = ± [tex]\sqrt{2}[/tex] ( add 6 to both sides )
x = 6 ± [tex]\sqrt{2}[/tex]
The zeros are x = 6 - [tex]\sqrt{2}[/tex] , x = 6 + [tex]\sqrt{2}[/tex]

The College Board states that the average math SAT score is 514 with a standard deviation of 117. Colleen gathered data from 50 students in her graduating class and found the average score to be 523. She thinks that her class’s math SAT score is different from the average. Which of the following are the correct null hypothesis and alternate hypothesis? H0: Mu = 514; Ha: Mu greater-than 514 H0: Mu not-equals 514; Ha: Mu = 523 H0: Mu = 514; Ha: Mu not-equals 514 H0: Mu = 514; Ha: Mu = 523.
From the hypothesis test, we have that:
The null hypothesis is [tex]H_0: \mu = 514[/tex].The alternative hypothesis is: [tex]H_1: \mu \neq 514[/tex]At the null hypothesis, it is tested if her average is the same as the national of 514, hence:
[tex]H_0: \mu = 514[/tex]
At the alternative hypothesis, it is tested if it is different, hence:
[tex]H_1: \mu \neq 514[/tex]
