A segment measures 10 units. One end of the segment has an endpoint at three, -6. What is another possible in point to this segment

Answers

if one end is -6 and the measure is 10 units long, there are 2 other possible ends. -16 or 6.

assumingn ya mean the oint (3,-6)

add or subtract 10 from x or y to get points 10 away

3-10=-7 so a point is (-7,-6)
3+10=13 so a point is (13,-6)
-6-10=-16 so a point is (3,-16)
-6+10=4 so a point is (3,4)

those are 4 out of inifnite points that we can get that are 10 units from (3,-6)
the points are (x,y) such that they satisfy the following equation:

Julia is a measuring a table for her room. The area of the tables 46 7/8 square feet. The length of the table is 7 1/2 feet. Julia does not want to purchase a table that is greater than 6 feet wide. Should she purchase the table? why or why not

Answers

In this question, you have given the table length (7. 1/2 feet) and the table maximal area (46 7/8 square feet). The question is about whether Julia buys a table greater than 6ft wide, in other words, we need to determine the table maximum width. The equation from this problem can be written as:
Table max area = 46 7/8 ft
Table length= 7 1/2 ft

Using area formula, the calculation for maximal width would be:
length * max width = max area
7 1/2 ft * max width = 46 7/8 ft
max width = 46.875/ 7.5 = 6.25ft

The answer to this question would be yes, she can buy a table with more than 6 ft width. But it should not more than 6.25ft width

Answers

The answer is D because -14.6 is the least and is the only one that has -14.6 first.

The correct answer is option D –14.6, –1.295, 1.07, 24.6, 159.

Given numbers: –14.6, 159, 1.07, –1.295, 24.6.

To order the numbers from least to greatest, we consider their values:

–14.6 (negative and smallest)–1.295 (negative and larger than –14.6)1.07 (positive and the smallest positive number in this list)24.6 (positive and larger than 1.07)159 (positive and largest)

Since we can't do anything at this point, we do

At this point, we can divide this by

(-4/7+((25xy/7+31y^2/7)/(7x^2+xy-6y^2)))/((x^2+4xy-2y^2)). After that, we can't use long division since the numerator's top x exponent is 1.

the difference of a positive integer and its inverse is 15/4. find the integer

Answers

If the integer is x, and the inverse is 1/x, we have x-1/x=15/4 (since difference is subtraction). Multiplying both sides by x, we get x²-1=15x/4. Next, we can subtract 15x/4=3.75x from both sides to get x²-3.75x-1=0. Using the quadratic formula, we get [tex]x= \frac{3.75+- \sqrt{(-3.75)^2-(4*-1*1)} }{2} = \frac{3.75+- \sqrt{14.0625+4} }{2} = 4, -0.25. [/tex]

Since it has to be a positive integer, we get x=4

Help!! what is -2r-1= -11

Answers

-2r - 1 = -11

So here you want to group all like terms onto either side.

So you can first do this by getting rid of the -1 by adding 1 instead.

-2r -1 + 1 = -11 + 1

-2r = -10

And then now you can just divide both sides by -2.

-2r = -10

/-2 /-2

r = 5

-2r-1= -11
+1 +1
-2r= -10
r=5

Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile. If she started at sea level and has hiked down to the fourth rest station, what is Sasha’s elevation now? Select all that apply.

a. -8/3
b. -4 2/3
c. 14/3
d. 2 2/3
e 4/3

Answers

Answer:

a. -8/3 miles below sea level.

Step-by-step explanation:

Sasha started at sea level and has hiked down to the fourth rest station.

Now sea level is 0.

Sasha takes a break at the rest stations every 2/3 of a mile.

This means she is down to 4 rest points means 4 times 2/3

This becomes = [tex]4\times(\frac{2}{3} )=\frac{8}{3}[/tex]

But the answer will be in negative as she is below 0.

So, correct answer is: a. -8/3 miles below sea level.

Shasha's elevation at the fourth rest station is 2 2/3

Position of rest station = 2/3 of a mile

Sea level = 0

The 4th rest station will be located at :

4 × 2/3 = 8/3

Therefore, the position of the fourth rest station from Shasha's starting position is (0 + 8/3) = 8/3

Since, she's hiking upward her position will be 8/3 = 2 2/3

Therefore, Shasha's elevation is

What is the surface area of 3x3x1?

Answers

Final answer:

The surface area of a 3x3x1 rectangular prism is calculated using the formula Surface Area (SA) = 2(lw + lh + wh), resulting in a total surface area of 30 cm².

Explanation:

The surface area of a rectangular prism with dimensions 3x3x1 can be calculated using the formula for surface area of a cube, which is slightly modified for a rectangular prism. The formula is Surface Area (SA) = 2(lw + lh + wh), where 'l' is the length, 'w' is the width, and 'h' is the height of the prism. In this case, the length (l), width (w), and height (h) are 3 cm, 3 cm, and 1 cm respectively.

To calculate the SA:

Multiply the length and width: 3 cm × 3 cm = 9 cm².Multiply the length and height: 3 cm × 1 cm = 3 cm².Multiply the width and height: 3 cm × 1 cm = 3 cm².Sum these areas and multiply by 2: (9 cm² + 3 cm² + 3 cm²) × 2 = 30 cm².

The surface area of the 3x3x1 rectangular prism is thus 30 cm².

Final answer:

The surface area of a 3x3x1 cube is 54 square units.

Explanation:

To find the surface area of a 3x3x1 cube, we need to calculate the total area of all its faces.

Since the cube has six faces that are all identical squares, we can find the surface area by multiplying the length of one side of the square by itself, and then multiplying that result by 6.

Surface Area = 6 x (3 x 3)

= 6 x 9

= 54

Therefore, the surface area of a 3x3x1 cube is 54 square units.
