Answer:
From his starting point of 85 3/4, he descended 17 9/20 meters
Step-by-step explanation:
We want to know how much farther he went down from his starting point.
103 1/5 - 85 3/4
S
tart off by making the denominators of both the numbers the same.
103 1/5 - 85 3/4
103 4/20 - 85 15/20
Make them into improper fractions
2064/20 - 1715/20 = 349/20
Make 349/20 into a mixed fraction
17 9/20
You are going to make three shelves for your father and have one piece of lumber 20 feet long. Your plan is to make the top shelf half a foot shorter than the middle shelf and to have the bottom shelf half a foot shorter than twice the length of the top shelf. How long is each shelf? t= length of the top shelf t=m-1/2 m = length of middle shelf b = length of bottom shelf. B=2t-1/2 t+m+b=20
Answer:
The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet
Step-by-step explanation:
Let t= length of the top shelf, m = length of middle shelf and b = length of bottom shelf.
Therefore:
t = m - 1/2; m = t + 1/2
Also, b = 2t - 1/2
The total of the three shelves is 20 feet, therefore:
t + m + b = 20
Substituting:
t + t + 1/2 + 2t - 1/2 = 20
4t = 20
t = 20/4
t = 5 feet
m = t + 1/2 = 5 + 1/2 = 5.5 feet
b = 2t - 1/2 = 2(5) - 1/2 = 9.5 feet
The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet
Help need to know if I did this right question in picture
Answer:
Wrong. If the line segment AB= 10, then the measure of AC= 10 as well. It's a right triangle. All the sides are the same.
Step-by-step explanation:
Answer: Not correct. The tic marks on the angles mean that this is an equilateral triangle
All the line segments are equal. If a length is given for one side of the triangle, the others are the same
All the angles are equal. The total of all the angles is 180. to find any one of them divide 180 ÷ 3
Step-by-step explanation: This looks like a test item, so we are not supposed post answers.
So I hope this is enough to help you make the corrections yourself.

Is this relation a function
Answer:
You can tell if a relation is a function if each input value only has ONE output value. Examples below
Step-by-step explanation:
The point (1,0) lies on the graph of
P(x) = x^4 - 2x^3 - x+2
A. True
B. False
Answer:
The given statement is true.
Step-by-step explanation:
Given function is:
[tex]P(x) = x^4 - 2x^3 - x+2[/tex]
And the given point is:
(1,0)
In an ordered pair, the first element is the input and second is the output. If we plug in the input to the function and get the respective output then the point lies on the graph of function.
For (1,0) we will put x = 1 in function and check whether we get 0 as output
[tex]P(x) = (1)^4 - 2(1)^3 - 1+2\\= 1-2(1)-1+2\\= 1-2-1+2\\=0[/tex]
Hence,
The given statement is true.

write the equation of a parellel to the given line that goes through the given point y=8x+3 (2,4)
Answer:
The equation of a parallel to the given line that goes through the given point (2, 4) is:
[tex]y=8x-12[/tex]
Step-by-step explanation:
Given the equation
[tex]y=8x+3[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is m = 8.
We know that the slopes of parallel lines are equal.
so, the slope of the perpendicular line will be = 8
Therefore, the equation of a parallel to the given line that goes through the given point (2, 4) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-4 = 8 (x-2)[/tex]
[tex]y-4 = 8x-16[/tex]
[tex]y = 8x-16+4[/tex]
[tex]y=8x-12[/tex]
What is the slope of the line represented by the equation y = 4/5x - 3
Answer:
the slope 4/5x and the y intercept is -3

17 times 0.0167. Can someone solve this step by step
Answer:
0.2839
Step-by-step explanation:
Can you tell me what part you are stuck on?
Answer:
0.2839
Step-by-step explanation:
-First, move the decimal over 4 places to the right to make 0.0167 into a whole number, which will turn into 167.
-Now, multiply 17 times 167 to get 2839.
-Finally, since the decimal from 0.0167 was moved 4 places to the right, it needs to be moved back 4 places to the left. Once it was moved back 4 places to the left, the answer should now be 0.2839
Hope this helps! :)

8. Which is not equivalent to 3p-2=6p+4?Explain.
a.) 3p=6p+6
b.) 3p=6
c.) -6=3p
d.)-3p-2=4
Answer:
b.) 3p=6 is not equivalent
Step-by-step explanation:
If you solve and do the same thing on both sides you will get every other solution except b.
Answer:
The correct answer is b) 3p = 6
Step-by-step explanation:
First, we need to find p:
3p - 2 = 6p + 4
-2 = 3p + 4
-6 = 3p
-2 = p
Now, we just need to plug p's value into each question:
a) 3p = 6p + 6
3(-2) = 6(-2) + 6
-6 = -12 + 6
-6 = -6
Since -6 = -6, a is not the correct answer.
b) 3p = 6
3(-2) = 6
-6 = 6
Since -6 ≠ 6, b is the correct answer.
c) -6 = 3p
-6 = 3(-2)
-6 = -6
Since -6 = -6, c is not the correct answer.
d) -3p - 2 = 4
-3(-2) - 2 = 4
6 - 2 = 4
4 = 4
Since 4 = 4, d is not the correct answer.
Therefore, b is the correct answer.

Value of an algebraic expression depends on the values of its variables usually. The value of [tex]2x^2[/tex] for given condition is obtained to be 18
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For the given case, we are given that [tex]x - 1 =2[/tex]
By this, we can get the value of the variable 'x' as:
[tex]x - 1 = 2\\\text{Adding 1 on both the sides, we get}\\x = 3[/tex]
Now, putting 3, in place of x, in expression [tex]2x^2[/tex], we get:
[tex]2x^2 = 2 \times (3^2) = 2 \times 9 = 18\\[/tex]
( sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, thus, [tex]2x^2 = 2 \times x^2[/tex])
Thus, the value of [tex]2x^2[/tex] for given condition is obtained to be 18

The lines in the graph of Part A don't intersect as two whole numbers on the coordinate grid. Estimate the values of the solution to the nearest one-fourth of a unit. The substitute the x- and y-values of the approximate solution into the two equations. How close do you get to the constant numbers in each equation?
Answer:
The solution lies at approximately (4.25,6.5).
Step-by-step explanation:
The estimation is moderately close for both of the equalizations. For the very first equation, the calculation appears in an amount that is barely 0.2125 units distant from the permanent. For the second equation, the calculation appears in an amount that is barely 0.25 units apart from the permanent.
please solve this equation and show work please tysm 3(g−7)=2(10+g)
Answer:
g=41
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(g−7)=2(10+g)
(3)(g)+(3)(−7)=(2)(10)+(2)(g)(Distribute)
3g+−21=20+2g
3g−21=2g+20
Step 2: Subtract 2g from both sides.
3g−21−2g=2g+20−2g
g−21=20
Step 3: Add 21 to both sides.
g−21+21=20+21
41
Step-by-step explanation:
3(g-7)=2(10+g)
3g-21=20+2g
3g-2g=20+21
g=41
