The area of a rectangle is at most 400 square centimeters. Write an inequality to represent the possible values for the height, h, for the height. The length is 16cm for one side

Answers

Answer:

1ft≤h≤25ft

Step-by-step explanation:

The area of a rectangle is expressed as;

Area = Length * height

A = Lh

If the area of a rectangle is at most 400 square centimeter, this is expressed as;

A ≤400

≤ means at most i.e it can not be greater than 400

Lh ≤ 400

Given L = 16

16h ≤ 400

h ≤ 400/16

h ≤ 25

Hence the possible values of the height are with the range 1ft≤h≤25ft since the dimension can not be negative

Answers

Answer:

c must be -4

Step-by-step explanation:

x^2 - 5x + c = 0 is a quadratic whose coefficients are a = 1, b = -5 and c = c.

The discriminant is b^2 - 4ac, and we know that b^2 - 4ac = 41.

Substituting -5 for b and 1 for a, we get:

(-b)^2 - 4(1)(c) = 41, or 25 - 4c = 41, or -4c = 16.  Thus, c must be -4, and the quadratic is

Tommy makes $200,000 per year. Tommy's monthly taxes are 10% for Federal Income Tax, 4.2% for Social Security Tax, 1.75% for Medicare Tax, and 0.5% for Local Taxes. What is Tommy's monthly Take Home Pay?

Answers

Answer: $‭13,925‬

Step-by-step explanation:

Tommy makes $200,000 per year.

He then has to pay taxes of 10% for Federal Income Tax, 4.2% for Social Security Tax, 1.75% for Medicare Tax, and 0.5% for Local Taxes.

His total taxes are therefore:

= 10% + 4.2% + 1.75% + 0.5%

= 16.45%

Taxes in dollars are:

= Monthly salary * taxes

= (200,000/12 months) * 16.45%

= $2,741.67

Monthly take home pay:

= Monthly salary - monthly tax

= 200,000 / 12 months - 2,741.67

= 16,666.67 - 2,741.67

= $‭13,925‬

Jan walks 2 miles at a constant rate of 3 miles per hour and then runs 1 mile at a constant rate of 8 miles per hour.

(a) What is Jan’s average speed for the entire trip?
(b) Is the average speed in part (a) equal to the average of Jan’s two speeds?

Answers

Answer:

(a).4.36 mph

(b) No

Step-by-step explanation:

We are given that

Jan covered distance,s1 =2 miles

Speed of Jan, a=3 mph

s2=1 mile

b=8mph

a.

We have to find the Jan' s average speed for the entire trip.

Average speed =[tex]\frac{2ab}{a+b}[/tex]

Using the formula

Average speed=[tex]\frac{2(3)(8)}{3+8}=4.36mph[/tex]

b.

Average speed with two speed

Average of Jan’s two speeds

[tex]=\frac{a+b}{2}[/tex]

=[tex]\frac{3+8}{2}=5.5 mph[/tex]

[tex]4.36\neq 5.5[/tex]

Hence, the average speed in part (a) is not equal to the average of Jan’s two speeds.

What is the independent and dependent variable in this problem?

Answers

Answer:

The height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.

Step-by-step explanation:

We know that the function

y = f(x)

where y is a function of x.

Here:

The input variable 'x' is called the independent variableThe output variable 'y' is called the independent variable because the value of output y depends upon the value of the input 'x'.

Given the function of the height of the ball as a function of time is modeled by the equation

h(t) = -16t² + 90t + 5

As the height of the ball depends upon the time as the height of the ball is a function of time.

Thus, the height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.
