b: |8 - 9| = 1

Step-by-step explanation:

The || marks indicate that whatever is inside of them will be converted to a positive number, if it is not already. However, this takes place AFTER any operations between the marks, such as a subtraction.

Answer:

I actual foot represents 0.01093 foot on paper

Step-by-step explanation:

Given that :

Actual side length of snack stand = 60 feets

Length of side on map = 20cm

Scaie :

60 feet = 20cm

1 foot = (20/60) cm

1 foot = 0.333 cm

1cm = 0.0328084 foot

0.333cm = (0.33 * 0.0328084) = 0.01093 feets

Scale :

I actual foot represents 0.01093 foot on paper

Answer:

x is equal to one and three fifths, or 1.6

Step-by-step explanation:

[tex]\frac{1}{2}x - 2 = 2(-x + 1)\\\frac{x}{2} - 2 = -2x + 2\\\frac{x}{2} + 2x = 2 + 2\\x + 4x = 4 + 4\\5x = 8\\x = 1.6[/tex]

Answer: A.

Step-by-step explanation: This is because a function cannot have two or more x values with the same f(x) value. If this happens, the function does not exist.

Answer:

28 feets

Step-by-step explanation:

Given that:

Height of ladder = 35

Distance between foot of ladder and wall base = 21 feets

The height of the ladder = h

Kindly refer to attachment for diagram illustration :

Using Pythagoras rule :

h² = 35² - 21²

h² = 1225 - 441

h² = 784

h =sqrt(784)

h = 28 feets

Height of ladder along the side of the building = 28 feets

Answer:

Step-by-step explanation:

Answer:

The answer is

[tex]y = 3x + 5[/tex]

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ↶

[tex]y = mx + b[/tex]

❃Since we already have the slope, we don't need to solve for that.

➊ First: We are going to find the y-intercept.

[tex]y = mx + b \\ 2 = 3( - 1) + b \\ 2 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: }{5 = b}[/tex]

➋Second: Plug in.

[tex]y = 3x + 5[/tex]

Answer:

the picture is black, pls retake

Step-by-step explanation:

Answer:

we conclude that:

[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]

Hence, options A and D are true.

Step-by-step explanation:

Given the expression

[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]

[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}=\frac{1\cdot \:\:1\cdot \:\:1\cdot \:\:1}{5\cdot \:\:5\cdot \:\:5\cdot \:\:5}[/tex]

                 [tex]=\frac{1}{5\cdot \:5\cdot \:5\cdot \:5}[/tex]

                 [tex]=\frac{1}{5^4}[/tex]

                 [tex]=\frac{1}{625}[/tex]

Checking options B and C:

Option B

[tex]\left(5^{-4}\right)^0=1[/tex]      

Option C

[tex]\frac{5^1}{5^4}=\frac{5}{625}=\frac{1}{125}[/tex]

Thus, options B and C are not equivalent!

Checking Option A

Option A

[tex]\left(5^{-2}\right)^2[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]

[tex]\left(5^{-2}\right)^2=5^{-2\cdot \:2}[/tex]

           [tex]=5^{-4}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]

           [tex]=\frac{1}{5^4}[/tex]

           [tex]=\frac{1}{625}[/tex]

Now, checking option D

Option D

[tex]5^2\cdot \:5^{-6}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]5^2\cdot 5^{-6}=5^{2-6}[/tex]

            [tex]=5^{-4}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]

            [tex]=\frac{1}{5^4}[/tex]

            [tex]=\frac{1}{625}[/tex]

Therefore, we conclude that:

[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]

Hence, options A and D are true.

Answer:

70 inches

Step-by-step explanation:

Larry forms a right triangle with the ground (this is one leg of a right triangle) and he is 24 inches from his shadow (this is the second leg).

74 inches is the hypotenuse of the right triangle

use pythagorean theorem:  a^2 + b^2 = c^2

let h = Larry's height

h^2 + 24^2 = 74^2

h^2 + 576 = 5476

h^2 = 4900

h = sq rt 4900

h = 70

Answer:

a = 16 and b = 13

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, so

CD = AB , that is

3a - 10 = 2a + 6 ( subtract 2a from both sides )

a - 10 = 6 ( add 10 to both sides )

a = 16

The diagonals of a parallelogram bisect each other, so

AO = CO , that is

2b = 26 ( divide both sides by 2 )

b = 13

Answer:the first one is d and the third one is 65% and I think the second one is 5 hours

Step-by-step explanation:

(PLZ READ )all you have to do to get the answer for the first one is divide for example on D it says 1 and then 5 and 2 and 10 first you divide 1 by 5 then 2 by ten and if they ALL have the same answer then they are proportional even if one does not have the same as All the rest it is not proportional.

and for the third one you can search it up

Answer:

It would take 6 hours for the fox to cross the 210 mile trail of the Sonoran Desert.

Step-by-step explanation:

210 miles divided by 7 miles is 30 miles. 30 miles multiplied by 12 minutes is 360 minutes or 6 hours.

Answer:

6 hours

Step-by-step explanation:

Not sure if this is correct, sorry if it isnt but basically I did 210/7 and got 30, then 30 x 12 to figureout how long it would take, i got 360 minutes and 360 min = 6 hours
