Answer:

20 + (-35)

Step-by-step explanation:

(-20) + 10 = -10

20 + (-35) = -15

Answer: 20+(-35)

Step-by-step explanation:

a.) -20+10

You owe me 20 dollars and you gave me 10 dollars already so how much more do you owe me? If you got you owe me 10 dollars, then you are correct. So the answer is -10 because the amount you owe is what still needs to be given so it is negative. (-10)

b.) 20+(-35) or 20-35

This problem would be you gave me 20 dollars but then took 35 dollars from me so how much do you owe you. You owe me 15 dollars since you gave me $20 a while ago and took from me. This would be a negative 15 since you owe it to me. (-15)

-15 is less that -10 since you would owe me more if you owed me 15 dollars. Also, -10 is closer to 0 than -15.

Answer:

Solution: x =5

Step-by-step explanation:

Solving Equations

Solve the following equation:

( 10 + 4 ) ( 5x - 22 ) = 3( 4x - 6 )

Operating:

14( 5x - 22 ) = 3( 4x - 6 )

Removing parentheses:

70x - 308 = 12x - 18

Subtracting 12x and adding 308:

70x -12x = 308 - 18

Operating:

58x = 290

Dividing by 58:

x = 290/58

x = 5

Solution: x =5

Answer:

1.71539657854

Step-by-step explanation:

Answer:

The correct option is;

This statement is true

Step-by-step explanation:

The given transformation are;

1) Vertical translation, y units down

2) Horizontal translation x units right

Therefore, the equivalent transformation is [tex]T_{(x, -y)}[/tex]

Whereby the coordinates of the of the point on the preimage with the largest y-coordinates are  (a, b), we have;

The coordinate of the corresponding point on the image = (a + x, b - y)

Given that the value of b is larger than the the y-coordinates values of al the points on the preimage, therefore, the value of b - y, will be the largest of the y-coordinates values on the image

Complete Question

Gatley’s Sport Shack and Camden Sports both carry the same brand of ski socks. At Gatley’s, 5 pairs of the ski socks cost $36.25. At Camden Sports, 4 pairs of the ski socks cost $32.60. A. What is the unit cost per pair of ski socks at both Gatley’s Sport Shack and Camden Sports?

Answer:

The unit cost per pair of ski socks at the Gatley’s Sport Shack is $7.252

The unit cost per pair of ski socks at the Camden Sports is $8.15

Step-by-step explanation:

a) At Gatley’s, 5 pairs of the ski socks cost $36.25.

The unit cost per pair of ski socks at the Gatley’s Sport Shack is calculated as:

5 pairs = $36.26

1 pair = $x

Cross Multiply

5 × $x = 1 × $36.26

$x = $36.26/5

$x = $7.252

Therefore, the unit cost per pair of ski socks at the Gatley’s Sport Shack is $7.252.

b) At Camden Sports, 4 pairs of the ski socks cost $32.60

The unit cost per pair of ski socks at the Camden Sports is calculated as:

4 pairs of socks is = $32.60

1 pair of socks = $x

4 × $x = 1 × $32.60

$x = $32.60/4

$x = $8.15

The unit cost per pair of ski socks at the Camden Sports is $8.15.

Answer:

95

Step-by-step explanation:

∠3 + 30° + 55° = 180° (angle sum property of a triangle)

∠3 + 85° = 180°

∠3 = 180° - 85°

∠3 = 95°

therefore, the measure of the third angle is 95°

Answer:

y=mx+b where m is the slope and b is where the line crosses the y axis.

THe line crosses the y axis at 0, 2 so 2 = b

the slope is how many units the point goes up/down and to the left/right from the y intercept. From 0, 2 to 3, 3 the point goes up 1 and over to the right 3 times. rise/run is slope so 1/3 is the slope:

y=1/3x+2

Step-by-step explanation:

Answer:

Y= -1/3x + 4

Step-by-step explanation:

Slope equation= y2 - y1/x2 -x1

Subtract 2-3/ 0-3 = -1/3

Choose an ordered pair to use for this problem. I chose 3,3.

Y-intercept equation- y = mx + b

3 = -1/3 * 3 + b

Multiply-1/3 * 3

3 = -1 + b

Add 1 to get rid of -1 and get b alone

3 + 1 = -1 + 1 +b

4= b

Now plug in your numbers to your equation.

Y= -1/3x + 4

Answer and Explanation:

The closet is 4 1/2 feet long, 2 2/3 feet deep, and 6 feet tall

Since we are not given width of the closet, we assume the base of the closet has equal width and length = 4 1/2 feet(closet base is a square)

Closet is 2 2/3 feet deep and 6 feet tall, therefore closet height internal = 8 2/3 feet

a. How much carpeting will she need?

The carpeting needed for the closet = area of base of the closet(square base)= 4 1/2* 4 1/2 = 4.5*4.5= 20.25 square feet

b. The athletic director wants to store cube boxers that are 1/2 foot wide. How many boxers will the storage hold?

Area of base = 20.25

Area of base of each cube on the floor = 0.5*0.5= 0.25

So we know that the base of the closet will hold

20.25/0.25= 81 boxer cubes

Or we could straight to the point

Find volume of the closet( the closet is clearly a cuboid) and divide by the volume of one cube to find number of cubes that will fit into the closet

Volume of the closet/cuboid = l*w*h =4.5*4.5*8.67/0.25

=702.27

Therefore number of boxer cubes to fit in closet= 702

Step-by-step explanation:

Responder:

57288.35 kN

Explicación paso a paso:

Paso uno:

datos dados

diámetro del tubo de entrada = 2 cm = 0.02 m

área = πd ^ 2/4

área = 3.142 * 0.02 ^ 2/4

área = 0.0003142m ^ 2

A1 = 3.14 * 10 ^ -4 m ^ 2

diámetro del pistón de salida = 32cm

masa del coche = 1800 kg

peso del coche = 1800 * 10 = 18000N

carga F2 = 18000N

Segundo paso:

Se requiere la presión aplicada P2

Aplicando la ecuación de presión para un fluido incompresible tenemos

P1 = F2 / A1

P1 = 18000 / 0,0003142

P1 = 57288351.36

P1 = 57288.35 kN
