Answer:

I dont know the answer but I can help

Step-by-step explanation:

every shape is 360 degrees so the ones with squares in the corner is 90 degrees add all the angles you know and subtract that from 360 then ÷ by the a glass that are missing hope that helps

Hello there. May somebody help me simplify this problem? It would be very kind.

marissa [1.9K]

Answer:

27 / (4x⁶y⁸)

Step-by-step explanation:

$\frac{4(3x^{2}y^{4})^{3}}{(2x^{3}y^{5})^{4}}$

When raised to a power, multiply the exponents.

$\frac{4(3^{3}x^{6}y^{12})}{2^{4}x^{12}y^{20}} \\\\\frac{2^{2}3^{3}x^{6}y^{12}}{2^{4}x^{12}y^{20}}$

When dividing, subtract the exponents.

$2^{2-4}3^{3}x^{6-12}y^{12-20}\\2^{-2}3^{3}x^{-6}y^{-8}$

Move negative exponents to the denominator.

$\frac{3^{3}}{2^{2}x^{6}y^{8}}\\\frac{27}{4x^{6}y^{8}}$

Item 1: sleeved dress $17.99

Oksana_A [137]

Answer:

<em>The final price including tax is $41.89</em>

Step-by-step explanation:

The following items are on sale:

Sleeved dress $17.99

Skirt $16.19

T-shirt $8.99

Subtotal $43.17

The cheapest item is the T-shirt for $8.99 and it will be discounted by 30%:

$8.99 - 30/100 * $8.99 = $8.99 - $2.70 = $6.29

The total sale price is now: $43.17-$2.70=$40.47

Now we add the 3.5% tax:

$40.47 + 3.5/100 * $40.47 = $40.47 + $1.42 = $41.89

The final price including tax is $41.89

Benford’s law states that the probability that a number in a set has a given leading digit, d, is

Fiesta28 [93]

Answer:

Benford’s law states that the probability that a number in a set has a given leading digit, d, is

P(d) = log(d + 1) - log(d)

The division property of logarithm should be use to make it as a single logarithm

P(d) = log ( (d + 1)/ d)

So the probability that the number 1 is the leading digit is

P(1) = log ( ( 1+1)/ 1)

P(1) = log ( 2)

P(1) = 0.301

1) Which is the measure of ∠A?

s344n2d4d5 [400]

Answer:

Part 1) Option A) 93°

Part 2) Option B) 138°

Part 3) Option A) 42°

Part 4) Option A) 21

Part 5) Option A) 54°

Step-by-step explanation:

Part 1) Which is the measure of ∠A?

see the attached figure N 1

we know that

m∠A+87°=180° -----> by supplementary angles (form a linear pair)

m∠A=180°-87°=93°

Part 2) Which is the measure of ∠C?

see the attached figure N 2

we know that

m∠C+42°=180° -----> by supplementary angles (form a linear pair)

m∠C=180°-42°=138°

Part 3) Which is the measure of ∠B?

see the attached figure N 3

we know that

m∠B and 42° are vertical angles

Remember that the vertical angles are a pair of congruent angles

m∠B=42°

Part 4) Find the value of x

see the attached figure N 4

we know that

64° and (3x+1)° are vertical angles

Remember that the vertical angles are a pair of congruent angles

64°=(3x+1)°

Solve for x

3x=64-1

3x=63

x=21

Part 5) Find the measure for ∠MQX

see the attached figure N 5

we know that

(3a+39)° and (5a+29)° are vertical angles

Remember that the vertical angles are a pair of congruent angles

(3a+39)°=(5a+29)°

Solve for a

5a-3a=39-29

2a=10

a=5

Find the measure of ∠MQX

m∠MQX=(3a+39)°

substitute the value of a

m∠MQX=3(5)+39=54°
