Answer:
It would take him 8 hours
Since every 50 miles takes 1 hour
━━━━━━━☆☆━━━━━━━
▹ Answer
8 Hours
▹ Step-by-Step Explanation
First, find the unit rate:
100 miles ÷ 2 hours = 50 mph
Now, we need to find the time it takes to drive 400 miles so we will divide:
400 miles ÷ 50 mph = 8 hours
If you are looking for total hours, you would add:
2 hours + 8 hours = 10 hours
If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.
Hope this helps!

Consider the product P(x) = (3x2 - 6x + 2)(7x + 3).
What is the numerical coefficient of the x term in P(x)?
Enter only a number for your answer.
Answer:
-4
Step-by-step explanation:
Notice that the only way to multiply 2 numbers from each of the polynomials and get an x term is to multiply a constant and an x term.
The only ways to do that is to multiply -6x by 3 and 7x by 2.
After you're done multiplying, just combine the 2 like terms:
-18x+14x
=-4x
Therefore, the coefficient of the x term is -4.
a forth of all students im Mr.Flitch class of 24 got A on the last math test.How many kids scored below A on the test?
A forth can be represented as 25% or 0.25 as a decimal. (100/4 = 25)
To determine how many kids got an A, we figure out was 25% of 24 is.
0.25 x 24 = 6
Therefore, 6 kids in the class got an A.

Which scenario is an example of the transfer of thermal energy by radiation?
A. Leftovers are warmed in a microwave oven.
O B. A person's body temperature falls as the person swims in the
ocean.
C. Warm air near a heater spreads out to the rest of the room.
D. A piece of chocolate melts in a person's hand.
Answer:
A
Step-by-step explanation:
The scenario that is an example of the transfer of thermal energy by radiation is warm air near a heater spreads out to the rest of the room. That is option C.
What is radiation?Radiation is the transfer of heat energy from an environment to another through movement of air in the space between them. There is no medium that is required for this transfer.
From the options, the warm air from the heater spreads out to the rest of the room through the movement of air.
Therefore, the scenario that is an example of the transfer of thermal energy by radiation is warm air near a heater spreads out to the rest of the room.

Please help me, linear equations. Hurry please :)
Answer:
C) 18
Step-by-step explanation:
All you have to do is solve the equation.
2.25x + 5 = 45.50 (subtract 5 on each side)
2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)
x = 18
40.50/2.25 = 18
Answer:
18 Miles
Step-by-step explanation:
If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.
Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

75%75, percent of the pot's volume.
How far up the pot will the soil reach?
Round to the nearest tenth.
Answer:
The soil will occupy in 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.
Step-by-step explanation:
The volume of a square based pyramid = V = a²h/3
a = base edge or side length = 36cm
h = height = 36cm
V = 36² × 36/3
V = 15552cm³
Luis wants to fill the pot with soil so that the soil takes up 75 % the pot's volume.
75% of the pot's volume =
75/100 × 15552cm³
= 11664cm³
The soil will occupy 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.
Answer:
The soil will reach about 32.7 cm up the pot.

Given mn, find the value of x.
Answer:
x = 32 degrees
Step-by-step explanation:
since there is a line intersecting both of the lines you would do the opposite number to solve the problem. basically what i am trying to say is.
A straight line equals 180 degrees
and the given angle is 148 degrees
so just subtract.
180 degrees - 148 degrees = 32 degrees
so x = 32 degrees
to see if it is reasonable, look at the angle
if you look you can see that it is an acute angle
so, since 32 degrees is an acute angle, the answer is also reasonable.
so like i said,
x = 32 degrees
The interior angles of parallel lines and a transversal are the angles between the parallel lines.
The value of x is 32 degrees
Alternate interior angles of a parallel line add up to 180 degrees.
So:
[tex]\mathbf{148 + x = 180}[/tex]
Subtract 148 from both sides
[tex]\mathbf{148 - 148+ x = 180 - 148}[/tex]
Evaluate like terms
[tex]\mathbf{x = 32}[/tex]
Hence, the value of x is 32 degrees

In 2005, the UT Longhorns scored 15 times to win the Big 12 Championship Game 70-3. All of their points came from touchdowns (6 points each) and extra point kicks (1 point each). How many touchdowns and extra points did the Longhorns have in that game? (For the purposes of this problem, touchdowns and extra point kicks count as separate "scores".
Answer:
The number of touch downs = 11
The number of extra points = 4
Step-by-step explanation:
The number of times UT Longhorns scored = 15 times
The composition of the scores = Touch down and point kicks
The points with which UT Longhorns won the game = 70-3
The points that came from each touch down = 6 points
The points that came from each point kick = 1 points
We have;
The number of touch downs + Point kicks = 15
The number of touch downs = 15 - Point kicks
Let the number of point kicks = P
Therefore;
The number of touch downs = 15 - Point kicks = 15 - P
The number of touch downs = 15 - P
Given that the total points of UT Longhorns = 70, we have;
6 × (15 - P) + 1 × P = 70
90 - 6·P + P = 70
5·P = 90 - 70 = 20
P = 4
∴ The number of point kicks = P = 4
The number of point kicks, extra points = 4
The number of touch downs = 15 - P = 15 - 4 = 11
The number of touch downs = 11
