Answer:

 B    a b^2 c^5/ d^4

Step-by-step explanation:

a^-3 b^2 c^3 d^-3 / (a^-4 b^-2c^-2d)

separate the terms

a^-3/a^-4 * b^2/b^-2  * c^3 /c^-2  d^-3 /d

when dividing, we subtract the exponents

a^ (-3--4)  b^(2--2) c^(3--2)  d^(-3-1)

a^ (-3+4)  b^(2+2) c^(3+2)  d^(-3-1)

a^1   b^2   c^5  d^-4

negative exponent go to the denominator if they are in the numerator

a b^2 c^5/ d^4

The coordinate of point T are (3,-11). The midpoint of line ST is (3,-9). Find the coordinates of point S
svetlana [45]

Answer:

(3,-7)

Step-by-step explanation:

Midpoint Formula

(3,-9) = ((3+x)/2 , (-11+x)/2)

Solve for x coordinate

3 =  \frac{3 + x}{2}  \\ 6 = 3 + x \\ 3 = x

Solve for y coordinate

- 9 =  \frac{ - 11 + x}{2}  \\  - 18 =  - 11 + x \\  - 7 = y

Therefore point s is (3, -7)

A collection of 36 coins consists of nickels, dimes and quarters. There are three fewer quarters than nickels and six more dimes
lina2011 [118]

Answer:

9 quarters, 12 nickels, and 15 dimes.

Step-by-step explanation:

Let's start by naming the number of quarters x.

That means that the number of nickels is x+3.

(There are three fewer quarters than nickels)

The number of dimes would be x+6.

(There are six more dimes than quarters)

We know the total number of coins is 36.

We can set up an equation.

quarters+nickels+dimes=36

x+x+3+x+6=36

Combine like terms.

3x+9=36

Subtract 9 from both sides.

3x=27

Divide both sides by 3.

x=9

There are 9 quarters.

Use given info to find the number of other coins.

9+3=12

There are 12 nickels.

9+6=15

There are 15 dimes.

The endpoints of two segments are given. Find each segment length to the nearest tenth. AB¯¯¯¯¯¯¯¯: A(0, 2), B(−3, 8) and CD¯¯¯¯
sleet_krkn [62]

Step-by-step explanation:

Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.

so,

AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45

AB = sqrt(45) ≈ 6.7

CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40

CD = sqrt(40) ≈ 6.3

Charlie has $12 saved already. He earns another $10 for each lawn he mows. How many lawns must he now before he has $100 saved?
sergeinik [125]
Answer. 100= 10x+ 12
Explanation. 100 represents the total money from mowing lawns after (x) jobs. x represents the amount of lawns he mows. Finally, 12 represents the amount of money he has regardless of how many lawns he mows. I hope this helps, let me know if it’s correct so others can use it :)
Good luck.
