Find the number that is exactly half way between -4 and 10
Answer:
7 as a halfway of a line
3 if you were using points on a graph
Step-by-step explanation:
10--4/2=7
use midpoint formula for 3
The number that is exactly halfway between -4 and 10 is 3
The distance between two point is the amount of length between the two points.
Midpoint of -4 and 10 is 10 - (-4) gives 10 + 4
The distance between -4 and 10 is 14 units
Halfway of the length between -4 and 10 is 14 /2 (7)
The number that is exactly halfway between -4 and 10 = -4 + 7 or 10 - 7 = 3
The number that is exactly halfway between -4 and 10 is 3

Answer:
h=12
Step-by-step explanation:
First look at the formula for finding the volume of a cone- [tex]V=\pi r^{2} \frac{h}{3}[/tex]
Next substitute any variables for values you already know- [tex]144\pi =\pi (6)^{2} \frac{h}{3}[/tex]
Then solve the equation.

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Starting from a full tank, can Diego's family drive the car for 14 days without the warning light coming on? Explain your reasoning.
Answer:
20 days
Step-by-step explanation:
Subtract 1.5 gallons from 14 gallons to obtain the number of days the car will run without the warning light going on: 12.5 gallons.
Dividing this result by 0.6 gallons/day, we get
12.5 gal
------------------- = 20.82 days. Round this down to 20 days. (We're not
0.6 gal/day dealing in partial days.)

A parabola is graphed such that the axis of symmetry is x = 3. One of the x-intercepts is (5, 0). What is the other x-intercept?
The axis of symmetry is the fold line that splits the parabola down the middle.
Now, since a parabola is symmetrical, every point, except the vertex, will have a mirror image of another point if we folded the parabola over the axis of symmetry.
So if we know the axis of symmetry is x = 3 and one of our points
has the coordinates (5, 0), the other point will have the coordinates (3, 0).
The axis of symmetry is always halfway between the x-intercepts.

MODELING WITH SYSTEMS OF INEQUALITIES
There are many situations that arise in business and engineering that necessitate systems of linear inequalities. The region in the xy-plane that solves the systems often represents all of the viable solutions to the system, so being able to visualize this region can be extremely helpful. As always, with modeling, it is important to really read the problems and understand the physical quantities involved.
(a) If John works 14 hours mowing and 30 hours at the bakery, does this satisfy all of the problem’s constraints?
(b) If x represents the hours John spends mowing and y represents the hours he spends at the bakery, write a system of inequalities that describes this scenario.
The question is incomplete. The complete question is :
John mows yards for his father's landscaping business for $ 10 per hour and also at a bakery for $ 15 per hour. He can work at most 52 hours per weak during the summer. He needs to make at least $ 600 per week to cover his living expenses.
a) If John works 14 hours mowing and 30 hours at the bakery, does this satisfy all of the problem’s constraints?
(b) If x represents the hours John spends mowing and y represents the hours he spends at the bakery, write a system of inequalities that describes this scenario.
Answer:
a). No
b). 10x + 15y ≥ 600
Step-by-step explanation:
a). Number of hours John works mowing = 14 hours
Number of hours John works at bakery = 30 hours
Therefore, according tot he question,
= 14($10) + 30($15)
= 140 + 450
= $ 590
This is not enough money. He needs to earn $ 600 per week.
b). Given :
x = hours John spends mowing
y = hours John spends at the bakery
Therefore, the inequalities which describes this situation is:
x + y ≤ 52
10x + 15y ≥ 600

A new car is purchased for $26,000 and over time its value depreciates by one half every 5 years. What is the value of the car years after it was purchased to the nearest hundred dollars?
Answer: $6,500
Step-by-step explanation:
Question says after 10 years.
The value of the car depreciates by 1/2 every year which is 50%, every 5 years.
In 10 years therefore, the car would have depreciated by half of its value, twice.
Use the future value formula:
= Amount * (1 + rate) ^ no. of periods
= 26,000 * ( 1 - 50%)²
= $6,500
Note: There are two periods because the depreciation is every 5 years and 10 years have gone by so the number of periods is: 10 / 5 = 2 periods
