X< or equal 10 feet : 8 inches ( x -number of steps)
10 feet=120 inches
x< or equal 120 in. :8 in.
x < or equal 15

if the step of the stairway is increasing the number of steps is decreasing, that is why I put the sign " < or equal"

Solve for v in terms of w, x, and y.<br> y=w+v–x

gladu [14]

Answer:

y - w + x

Step-by-step explanation:

y = w + v - x

or y - w + x = w + v - x - w + x [adding x and subtracting w from both sides]

or y - w + x = v

Therefore, v = y - w + x

6. Identify the slope of a line parallel to the given<br> line.<br> y- 4 = + (x + 8)

AleksAgata [21]

Answer: slope = 1

Step-by-step explanation:

For two lines to be parallel then they have the same slope , if the slope of line 1 is M1 and then slope of line 2 is M2 , if they are parallel then M1 = M2.

Given; y- 4 = + (x + 8)

Make y the subject of the formula , so that the equation can be in slope - intercept form , that is in the form y = mx + c , where m is the slope and c is the y - intercept.

y - 4 = x + 8

Add 4 to both sides

y = x + 8 +4

y = x + 12

since the coefficient of x is 1 , this means that the slope is 1 , any line that will be parallel to this line must have a slope which is 1

The vertices of parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0). ABCD is reflected over the x-axis to create parallelogr

Scorpion4ik [409]

So, coordinates of QRST will be:

Q(2,−1),R(3,−4),S(5,−3),T(4,0)

Option D is correct.

Step-by-step explanation:

The vertices of given parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0).

ABCD is reflected over the x-axis to create parallelogram QRST

We need to find coordinates of QRST.

When the graph is reflected across x-axis, the x-coordinate remains the same, while y-coordinate becomes opposite i.e the sign is changed of the given coordinate.

So, coordinates of QRST will be:

Q(2,−1),R(3,−4),S(5,−3),T(4,0)

All the y-coordinates have been converted to their opposite signs

So, Option D is correct.

Zoey wants to use her computer tablet throughout a 6-hour flight. Upon takeoff, she uses the tablet for 2 hours and notices that

6 hours Zoey can expect from the tablet on a full battery charge if the battery dropped by 33%, from 100% to 67%.

<h3>What is percentage?</h3>

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

Zoey wants to use her computer tablet throughout a 6-hour flight. Upon takeoff, she uses the tablet for 2 hours and notices that the battery dropped by 33%, from 100% to 67%.

Let's suppose x hours Zoey can expect from the tablet on a full battery charge.

The value of x can be calculated using:

x = (2×100)/33

x = 200/33

x = 6.06 ≈ 6 hours

Thus, 6 hours Zoey can expect from the tablet on a full battery charge if the battery dropped by 33%, from 100% to 67%.
