The gross income of David Vaughn is $785 per week. His deductions are $42.25, FICA tax; $90.33, income tax; 2% state tax; 1% cit

TEA [102]

Vaughn's net income will be the gross income minus any deductions. (2% of 785 is 15.70, 1% of 785 is 7.85, and 3% of 785 is 23.55.)

It will be easier to add together all the deductions, and then subtract that sum from 785:

42.25 + 90.33 + 15.70 + 7.85 + 23.55 = 179.68
785 - 179.68 = 605.32

A snail moves at the speed of 76 millimeters per minute. Nancy writes the following steps to calculate this speed in centimeters

gizmo_the_mogwai [7]

Answer:

The step 3 is incorrect in the conversion, is not necessary

Step-by-step explanation:

we have

The speed is $76\frac{mm}{min}$

we know that

1 mm=0.1 cm

1 min=1/60 h

$76\frac{mm}{min}=76(0.1)/(1/60)=76(0.1)(60)=456\frac{cm}{h}$

step 1

Multiply 76 by 0.1

$76(0.1)=7.6$

The step 1 is correct

step 2

Multiply the result obtained in step 1 by 60.

$7.6(60)=456$

The step 2 is correct

step 3

Multiply the result obtained in step 2 by 60

This step is not correct

therefore

The step 3 is incorrect in the conversion, is not necessary

Lúcia is using energy at a rate of 420 kilocalories (kcal) per hour (h) ice skating.

Flura [38]

420000 calories is 60 mins so 420000/60= 7000/min I think :)

What is the value of x? sin55°=cosx Enter your answer in the box. x = °

rodikova [14]

ANSWER

x=35°

EXPLANATION

The sine and cosine ratio are complementary trigonometric ratios.

This means that:

sin(A)°=cos(90-A)°

The given equation is:

sin(55)°=cos(x).

This implies that,

x=90-55

x=35°
