If the average baby blue whale grows at a rate of 1.5 inches a day, how many days does a baby whale grow to reach 47.075 inches? (Round to the nearest hundredth of a day)
x = # of days.
1.5x = 47.075
Divide both sides by 1.5
x = 31.38 days

Do two points always, sometimes, or never determine a line? Explain.
Answer: sometimes
explanation:
if there are two points then there could be a line to connect them, however, there could always be two points that are separate on their own.
Answer:
Always
Step-by-step explanation:
If 2 distinct points lie on the plane then it determines the line. You can also verify if you can find the slope, with these 2 coordinate points, and then find the equation of the line but using point slop form and/or slope intercept form which is y=mx+b

Answer:
a = 1
Step-by-step explanation:
Step 1: Write equation
a - 2(4 - a) = 7a - 12
Step 2: Solve for a
Distribute -2: a - 8 + 2a = 7a - 12
Combine like terms: 3a - 8 = 7a - 12
Subtract 3a on both sides: -8 = 4a - 12
Add 12 on both sides: 4 = 4a
Divide both sides by 4: a = 1
Step 3: Check
Plug in x to verify if it's a solution.
1 - 2(4 - 1) = 7(1) - 12
1 - 2(3) = 7 - 12
1 - 6 = -5
-5 = -5
Answer:
a = 1Step-by-step explanation:
equation given: a - 2(4 - a) = 7a - 12
distribute and expand the equation
a - 8 + 2a = 7a - 12
combine similar terms:
a + 2a - 7a = -12 + 8
simplify:
-4a = -4
a = -4 / -4
a = 1proof that a = 1
a - 2(4 - a) = 7a - 12
1 - 2(4 - 1) = 7(1) - 12
1 - 2(3) = 7 - 12
1 - 6 = -5
-5 = -5 therefore, the a = 1 is correct.
a high school football player is practicing his frield goals kicks. The equation h=-9t²+45t where t is the number of seconds gone by and h is the height of the ball in feet. how long does it take for the ball to hit the ground
h = -9t^2 + 45t
First, let's factor the equation.
h = -9t(t - 5)
Let's set both terms equal to zero.
-9t = 0
Divide both sides by -9
t = 0
t - 5 = 0
Add 5 to both sides.
t = 5
We know that it took more than 0 second sto hit the ground, therefore, the only answer that makes sense is t = 5
It took 5 seconds for the football to hit the ground.

Mark is solving an equation where one side is a quadratic expression and the other side is a linear expression. He
sets the expressions equal to y and graphs the equations. What is the greatest possible number of intersections for
these graphs?
none
one
two
infinitely many
Answer:
The answer would be two because one of the lines would be a parabolic line and parabolic lines only have at the most two solutions.
The greatest possible number of intersections for the graphs is two.
What is the greatest possible number of intersections of the graph?It follows from the task content that the two graphs involved are;
A linear and quadratic graph.By convention, a quadratic graph produces a parabola and a linear graph produces a straight line. On this note, it follows that the best case of intersection is when the straight line crosses over the parabola and hence leading to two points of intersection.

A man drove his car a distance of 315 miles in 5 hours. If continuing at this rate is possible, he will travel miles in 9 hours. (5 points) Blank 1:
Answer:
567 miles
Step-by-step explanation:
Total distance travelled till now = 315 miles
Total time taken to cover the above distance = 5 hours.
Distance covered in each hour = [tex]\frac{315}{5} = 63[/tex]
Thus, it means in each hour it covers the distance of 63 miles.
Assuming the same speed can be continued and maintained, the total distance that can be covered in 9 hours shall be:
63 miles in each hour [tex]\times[/tex] 9 hours = 567 miles.
Answer:
567 miles

15 divided by 266 I need R
Answer:
Step-by-step explanation:
You could use a calculator or you could perform long division to find the remainder of 15/266. There is no integer quotient, other than 0 (zero). That means 15 is the remainder.
Supposing you were dealing with 266/15 (which is really a different problem). This division produces an integer quotient and a remainder:
266

4-7x=1-6x can someone please solve and show the work :)
Answer:
x = 3
Step-by-step explanation:
Simplifying
4 + -7x = 1 + -6x
Solving
4 + -7x = 1 + -6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6x' to each side of the equation.
4 + -7x + 6x = 1 + -6x + 6x
Combine like terms: -7x + 6x = -1x
4 + -1x = 1 + -6x + 6x
Combine like terms: -6x + 6x = 0
4 + -1x = 1 + 0
4 + -1x = 1
Add '-4' to each side of the equation.
4 + -4 + -1x = 1 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 1 + -4
-1x = 1 + -4
Combine like terms: 1 + -4 = -3
-1x = -3
Divide each side by '-1'.
x = 3
Simplifying
x = 3

Answer:
Step-by-step explanation:
a.
let A= number 5
B=number >3
P(A)=1/6 {5}
P(B)=3/6 {4,5,6}
p(A∩B)=1/6 {5}
P(AUB)=P(A)+P(B)-P(A∩B)=1/6+3/6-1/6=3/6=1/2
b.
let event C=number<5
D=even number
C=[1,2,3,4}
D={2,4,6}
C∩D={2,4}
P(C)=4/6
P(D)=3/6
P(C∩D)=2/6
P(C∪D)=P(C)+P(D)-P(C∩D)=4/6+3/6-2/6=5/6
c.
let event E=number 2
F= an odd number.
E={2}
F={1,3,5}
E∩F={}
P(E)=1/6

[tex]B = \frac{6D + 18 {f}^{3} }{M} [/tex]Step-by-step explanation:
[tex] - 3 {f}^{3} + \frac{1}{6} MB = D [/tex]
Multiply through by 6 to eliminate the fraction
That's
[tex] - 18 {f}^{3} + MB = 6D[/tex]
Move - 18f³ to the right side of the equation
That's
[tex]MB = 6D + 18 {f}^{3} [/tex]
Divide both sides by M to make B stand alone
That's
[tex] \frac{MB}{M} = \frac{6D + 18 {f}^{3} }{M} [/tex]
We have the final answer as
[tex]B = \frac{6D + 18 {f}^{3} }{M} [/tex]

Step 1:

Answer:
- 2x
Hope This Helps :)
Answer:
-2x
Step-by-step explanation:
Like the other problem, we want to combine our like terms(in this case, all terms with x's). In order to do this, all you have to do is ignore the x's and then add the numbers together. -12 + 10 = 2. Now that we've added them together, you can add the x back to get 2x.
Natalie is in the business of manufacturing phones. She pays a cost of $50 per
phone produced for materials and labor and also must pay a daily fixed cost
of $900 to rent the building and equipment. Make a table of values and then
write an equation for C, in terms of p, representing total cost, in dollars, of
producing p phones in a given day.
Answer:
C = 50p +900
Step-by-step explanation:
Table: (phones, cost) = (0, 900), (1, 950), (2, 1000).
Equation: C = 900 +50p
__
The fixed cost (900) is the "y-intercept" of the equation in slope-intercept form. The cost per phone (50) is the "rate of change" or slope.

The value of y is 27. (first option.)
isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
27
Step-by-step explanation:
2(3y + 6 +3)
2(9 + 3y)
18 + 6y
18 + 6y = 196 -16
6y =196 -16 -18
6y = 162
162 divided by 6 = 27
y =27
