Lightning strikes Earth 1000 times in 10 seconds. How many seconds does it take for lightning to strike 7250 times? It takes seconds for lightning to strike 7250 times.
Answer:
1000 / 10 = 100 strikes per second. Now, multiply by 12 to find the number of strikes that occurred. 100 * 12 = 1200 strikes in 12 seconds. Part B: Divide the number of seconds to the number of lightning strikes to find the average rate. 10 / 1000 = 0.1 seconds per strike. Now, multiply by 7250 to find the number of seconds that passed.

yall this one too i need help quick guys plz and ty
Answer:
b. (4,2)
Step-by-step explanation:
step one: isolate x in the first equation
substitute x=6-y: [tex]\begin{bmatrix}2\left(6-y\right)-2y=4\end{bmatrix}[/tex]
[tex]\begin{bmatrix}12-4y=4\end{bmatrix}[/tex]
[tex]-4y=-8[/tex]
[tex]y=2[/tex]
step two: isolate y in the second equation, substitute y=2
[tex]x=6-y[/tex]
[tex]x=6-2[/tex]
[tex]x=4[/tex]
Answer:
b
Step-by-step explanation:
Given the 2 equations
3x + 3y = 18 → (2)
2x - 2y = 4 → (2)
Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term
6x + 6y = 36 → (3)
6x - 6y = 12 → (4)
Add (3) and (4) term by term to eliminate y
12x + 0 = 48
12x = 48 ( divide both sides by 12 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
3(4) + 3y = 18
12 + 3y = 18 ( subtract 12 from both sides )
3y = 6 ( divide both sides by 3 )
y = 2
solution is (4, 2 ) → b

Write two different
expressions to find the total cost of an item
that costs $a if the sales tax is 6%. Explain
why the expressions give the same result.
Answer:
Total cost = $a + 0.06a
Total cost = a(1 + 0.06)
Step-by-step explanation:
Given that :
Cost of item = $a
Sales tax = 6%
Total cost = cost of item + sales tax
Total cost = $a + (6% of a)
Equation 1:
Total cost = $a + 0.06a
Equation 2:
Total cost = $a + 0.06a
Total cost = a(1 + 0.06)

Aliyah rode her bike at a speed of 10 miles per hour for 1.5 hours and then traveled at a speed of 7.5 miles per hour for 2 hours. What is the total distance that Alyah rode her bike during this time?
Answer:
Step-by-step explanation:
S(peed) = 10 mph
time = 1.5 hours
distance = s * time
distance = 10 * 1.5 = 15 miles
s = 7.5 mph
t = 2 hours
d = s * t
d = 7.5 * 2 = 15
Here total distance = 15 + 15 = 30 miles.

Can someone help me figure this out I'm completely lost and this is due in like an hour, the question is "Use the diagram to find the length of GH."
Answer:
GH = 4
Step-by-step explanation:
GH = AB due to congruency markings therefore
5y - 8 = 3y
-8 = =2y
4 = y
Answer:
GH=12
Step-by-step explanation:
You use what this other solution to the answer was. However, they did not include that GH is 3y, so while one y=4, 3y=12. Therefore, GH=12
Answer this, please.
The population of town is 32600. about 27% are over 60 years old. About 19% are 16 or under. How many are between 16 and 60?
Answer:
Number of population between 16 and 60 =17,604
Step-by-step explanation:
population of town = 32600
Percentage of people over 60 years old=27%
Percentage of people 16 or under =19%
Percentage of people between 16 and 60= 100%-(27% +19%)
100-(46) =54%
Number of population between 16 and 60 =Percentage of people between 16 and 60 x population of town
=54% x 32600
=17,604

Step-by-step explanation:
so in order to solve this question we are going to plug in u for 2^x
3((2^x)/2)=2^x+4
3u/2=u+4
3u=2u+8
u=8
we can put 2^x back into the equation in order to find x
