Step-by-step explanation:

The properties of exponents useful here are ...

a^0 = 1 . . . . for a ≠ 0

a^-b = 1/a^b

[tex]4^{-2}\cdot 12^{-1}\cdot 12^0=\dfrac{1}{4^2}\cdot\dfrac{1}{12}\cdot 1\\\\=\dfrac{1}{16\cdot12}=\boxed{\dfrac{1}{192}}[/tex]

Which statement best describes a unit rate?

1. John drove 350 miles in 5 hours

2. John drove 10 miles

3. John drove a car and a motorcycle

4. John drove 25 miles in 1 hour

Answers

Answer:

4. John drove 25 miles in 1 hour

Step-by-step explanation:

The unit rate is the number of something per unit. There should be a first number and the second number should always be 1.

The statement which best describes a unit rate is John drove 25 miles in 1 hour .

What is unit rate?

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

According to the question

Best describes a unit rate is that which have second term as 1 unit

So,

Only John drove 25 miles in 1 hour satisfy the condition ,

Hence, The statement which best describes a unit rate is John drove 25 miles in 1 hour .

We are given:

Parallelogram CDEF∠C = 13x - 10∠D = 5x + 10

To Find: ∠E

Concept Used:

Adjacent angles of a Parallelogram are Supplementary

Finding the value of 'x':

Since adjacent angles of a parallelogram are Supplementary:

∠D + ∠C = 180

5x + 10 + 13x - 10 = 180 [replacing the values of angle C and D]

18x = 180

x = 10 [dividing both sides by 18]

__________________________________________________________

Finding Measure of Angle D:

We are given that:

∠D = 5x + 10

∠D = 5(10) + 10 [since x = 10]

∠D = 60°

__________________________________________________________

Finding the measure of ∠E:

∠D and ∠E are Adjacent angles

Since Adjacent angles are Supplementary:

∠D + ∠E = 180

60 + ∠E = 180

∠E = 120° [subtracting 60 from both sides]

Hence, the measure of ∠E = 120°

[tex]360 - m∠1 + m∠3 = m∠2 + m∠4[/tex]

Franklin made $165,000 for the tax year
2017. How much did he pay in FICA taxes ?

Answers

Answer: $‭10,278.9‬0

Step-by-step explanation:

FICA taxes comprise of both the Social Security tax and the Medicare tax rate which in 2017 were 6.2% and 1.45% of income respectively.

The Social security portion is subject to a limit of $127,200 in income but there is no limit for the Medicare tax.

Franklin FICA = (127,200 * 6.2%) + (165,000 * 1.45%)

= ‭7,886.4‬0 + ‭2,392.5‬0

= $‭10,278.9‬0

Answers

Answer:

1). Option (b)

2). Option (d)

3). Option (d)

Step-by-step explanation:

Question (1)

For Pythagoras triplet,

(Largest number)² = (Number 1)² + (Number 2)²

a). 5² = 5² + 2²

25 = 25 + 4

25 = 29

Not True.

b). 5² = 3² + 4²

25 = 9 + 16

25 = 25

True.

c). 10² = 1² + 5²

100 = 1 + 25

100 = 26

Not true.

d). 2² = 2²+ 2²

4 = 4 + 4

4 = 8

Not true.

Therefore, Option (b) is correct.

Question (2)

1 - [tex]\frac{1}{5}[/tex] = [tex]\frac{5}{5}-\frac{1}{5}[/tex]

= [tex]\frac{5-1}{5}[/tex]

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

Therefore, Option (d) is the answer.

Question (3)

Property of triangle → Sum of lengths of two sides of a triangle should be greater than the measure of third side.

a). 6 + 3 > 2 ⇒ 9 > 2 [True]

6 + 2 > 3 ⇒ 8 > 3 [True]

2 + 3 > 6 ⇒ 5 > 6 [False]

Triangle is not possible.

b). 2 + 8 > 3 → 10 > 3 [True]

8 + 3 > 2 → 11 > 2 [True]

2 + 3 > 8 → 5 > 8 [False]

Triangle is not possible.

c). 5.5 + 2.5 > 2.5 → 8 > 2.5 [True]

5.5 + 2.5 > 2.5 → 8 > 2.5 [True]

2.5 + 2.5 > 5.5 → 5 > 5.5 [False]

Triangle is not possible.

d). 3 + 6 > 7 → 9 > 7 [True]

3 + 7 > 6 → 10 > 6 [True]

7 + 6 > 3 → 13 > 3 [True]

These are the sides of a triangle.

Therefore, Option D is the answer.

If y=-7 when = -21, determine x when y= 9

Answers

Correct Question :-

If y = - 7 & x = - 21 , determine x when y = 9

Given :-

y = - 7x = - 21

We need to find :-

When y = 9 find x

Solution :-

Using proportion ,

- 7 : - 21 : : 9 : x

By means & extremes ,

=> - 7x = - 21 × 9

=> x = ( - 21 × 9 ) / - 7

=> x = 3 × 9

=> x = 27

Hence , when y = 9 → x = 27
