Max is already 224 miles into his road trip. If he is averaging 52 miles per hour and the trip is 640 miles total, how many more hours does he have left to drive?
x - hours left to drive
Answer:
8 hours.
Step-by-step explanation:
1. Subtract 640-224=416
2. Divide 416/52
3. 8 hours
8 hours.
Step-by-step explanation:
We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.
Let us find the remaining distance of trip by subtracting the distance already covered from total distance.
Remaining Distance = 640 miles - 224 miles
Remaining Distance = 416 miles
We will use formula: Time = Distance/Speed to find the number of hours Max still have to drive.
Time = 416 miles/52 miles/hour
Time = 416 miles/52 × hour/miles
Time = 416/52 hour
Time = 8 hours
Therefore, Max have left 8 more hours to drive.
Write the Pythagorean theorem equation in an equivalent form with the a² isolated.
Answer:
[tex]a^{2}= -b^{2}+c^{2}[/tex]
Step-by-step explanation:
Rewrite the Pythagorean Theorem equation in terms of [tex]a^{2}[/tex].
[tex]a^{2}+b^{2}=c^{2}[/tex]
Subtract b squared from both sides.
[tex]a^{2}= -b^{2}+c^{2}[/tex]
Answer:
A^2=-B^2+H^2
Step-by-step explanation:
A^2+B^2=H^2
Isolate A^2. Subtract B^2 from both sides.
A^2=-B^2+H^2

4. x= 9
Step-by-step explanation:
3. Cross multiply: -6m=90
Solve: m= -15
4. Cross multiply: 7x+7=10x-20
Solve: x=9
Step-by-step explanation:
Here,
-m=10*9/6
or,-m=90/60
or,-m=15
or,-m=-(-15)
and, m=-15
2
Here,
(x+1)*7=(x-2)*10
or,7x+7=10x-20
or,7+20=3x
or,x=27/3
therefore, x=9ans

Explain the relationship between a strategy, such as number sense, and a written method , such as partial products or area models , for multiplying decimal number's.
Answer:
Hello
Step-by-step explanation:
You can take away the decimals
for example 0.33 x 0.7
do 33 x 7
which is 231
the 0.33 has 2 decimal spaces because there are 2 digits after the point
0.7 has 1 decimal place because there is 1 digit after the point.
so in total, there is 3 decimal
because you do 2 + 1
3
from the left, you count backwards and add the decimal point
the final answer should be 0.231
hope it helped

Answer:
27
Step-by-step explanation:
Answer:
$27
Step-by-step explanation:
substitute the value of p (price of the package of henna powder) which has been given as $12 and the value of s (price of the squeeze bottle) which has been stated as $3 into the equation from part b).
since the equation is 3(p-5) + 2s
write 12 instead of p, and 3 instead of s.
then solve the equation.
= 3(12-5) + 2(3)
= 3(7) + 2(3)
= 21 + 6
= 27

Question A: A
Question B: C
Question C: B
Step-by-step explanation:
Below is a graph of p, an insect population, w weeks after it was first measured. The population grows exponentially.
Write an approximate domain and range for this situation.
Write an equation relating p and w.
The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]p = 300 * 3^w[/tex]
From the graph, we have the following ordered pairs
(1,900) and (3,8100)
An exponential function is represented as:
[tex]p = ab^w[/tex]
At the point (1,900), we have:
ab = 900
At the point (3,8100), we have:
ab^3 = 8100
Divide both equations
[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]
Evaluate the quotients
[tex]b^2 = 9[/tex]
Take the square roots of both sides
b = 3
Recall that:
ab = 900
So, we have:
3a = 900
Solve for a
a= 300
Hence, the equation is:
[tex]p = 300 * 3^w[/tex]
