An emperor penguin travels a distance of 70 miles each year back to the place of its birth. If that same penguin moves at a speed of 2.4 miles per hour, the function d = 70 – 2.4t represents its distance d from its birthplace t hours after it has started its journey home. Find the zero of this function.

Answers

Answer 1

Answer:

29.17 hours

Step-by-step explanation:

to find the zero of the function, set d to equal zero, so

0 = 70 - 2.4t

-70 = -2.4t

-70/-2.4 = t

29.17 = t

Answers

Answer:

x and y can be any two numbers greater than zero such that y is also greater than x

D.no more than 45

C.50 miles per hour

Step-by-step explanation:

Let the two numbers be such that x< y because we have been given y/x>1 and x/y< 1 .

Suppose we take y= 9 and x= 3 then

9/3 > 1

3>1

Also

3/9 < 1

1/3 < 1

x and y can be any two numbers greater than zero such that y is also greater than x

2. Total weight that can be carried is 3000 pounds.

The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.

The smaller machines weigh 60 pounds

The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.

3. Total distance = Speed * time

                           = 48 * (40/60) = 32 miles

New distance = 32+ 8= 40 miles

New time = 48 minutes

Speed = distance / time = 40/ 48/60=  50 miles per hour

Answer:

The equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]

Option H is correct.

Step-by-step explanation:

We need to write an equation for the line that is parallel to the given line [tex]y=\frac{3}{4} x-9[/tex] and point (-8,-18)

The equation of required line will in in form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope m and b y-intercept for new line.

Finding slope:

When two lines are parallel, they have the same slope.

The slope of given line can be found by comparing the equation [tex]y=\frac{3}{4} x-9[/tex] with [tex]y=mx+b[/tex]

So, m = 3/4

The slope of new line will be: [tex]m=\frac{3}{4}[/tex]

Finding y-intercept:

Using slope m = 3/4 and point (-8,-18) we can find y-intercept

[tex]y=mx+b\\-18=\frac{3}{4}(-8)+b\\-18=-6+b\\b=-18+6\\b=-12[/tex]

So, y-intercept is b=-12

The equation of new line having m = 3/4 and b=-12 is:

[tex]y=mx+b\\y=\frac{3}{4}x-12[/tex]

So, the equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]

Option H is correct.

At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75. The sales tax is $0.98 and they leave a tip of $5.85. How much did Brianna and Naomi spend in all?

Answers

Given :

At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75.  

The sales tax is $0.98 and they leave a tip of $5.85.

To Find :

How much did Brianna and Naomi spend in all.

Solution :

Total expenses, T = Food + tax + tip

T = $( 6.50+9.75) + $0.98 + $5.85

T = $( 16.25 + 0.98 + 5.85 )

T = $23.08

Therefore, total expenses is $23.08 .

Hence, this is the required solution.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

--5x - 9y = 33

-y - 1 = x

Step 2: Simplify systems

5x - 9y = 33

-y - 1 = x

Step 3: Solve for y

Substitute:                              5(-y - 1) - 9y = 33Distribute 5:                            -5y - 5 - 9y = 33Combine like terms:               -14y - 5 = 33Isolate y term:                         -14y = 38Isolate y:                                  y = -19/7

Step 4: Solve for x

Define:                              -y - 1 = xSubstitute:                        -(-19/7) - 1 = xSimplify:                            19/7 - 1 = xSubtract:                           12/7 = xRewrite:                             x = 12/7

Maya is interning at a law firm over the summer and is paid by the hour. Her hourly wage is $52. Write two equations represent the proportional relationship between the wages she earns (w) and the number of hours (h).

Answers

Answer:

The two equations are;

w = 52 h

and h = w/52

Step-by-step explanation:

From the question, we are told that she earns $52 in an hour

So therefore ,

W(h)= 52h

where h is the number of hours she has worked and w is the wages earned for the number of hours worked

The two equations are;

w = 52h

or w/h = 52

Step-by-step explanation:

The rate of change for the graph is 2 so we can rule anything out that shows A has a larger rate of change. Now we look at the y intercept on the graph which is -2. The one in the function is 2 so we eliminate anything that says B has a greater y intercept this should give you the answer

The story of the telephones invention in 1876 is one of hard work, determination, and triumph. Many accounts make it sound like a fairy tale.
