Terrell wrote that 5 – 4.2 = 8. Which statement about his answer is true? CLEAR CHECK 8 is wrong because a number gets smaller, not larger, when you take 4.2 from it. 8 is right because 50 – 42 = 8. 8 is right because 4.2 + 8 = 5. 8 is wrong because you cannot subtract a decimal from a whole number.
Answers
Answer:
a) is wrong because a number gets smaller, not larger, when you take 4.2 from it
Step-by-step explanation:
Given
[tex]5 - 4.2 = 8[/tex]
Required
Determine which of the options is true
First, we need to solve for 5 - 4.2
[tex]5 - 4.2 = 0.8[/tex]
Compare this answer with Terell's answer (8)
We observe that: [tex]0.8 \neq 8[/tex]
This implies that; Terell is wrong
The two options that support the answer being wrong are (a) & (d)
Analyzing (a):
5 should get smaller when 4.2 is subtracted from it.
This isn't the case in Terell's solution.
Hence, (a) is true
Analyzing (d):
d is wrong because a decimal can be subtracted from a whole number
Hence, (a) answers the question

A new video game is expected to sell 120 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 15(x - 1) where x is the number of hours. What is the
function that shows total sales, including the first hour? (1 point)
s(x) = 15(x - 1) - 120
s(x) = 120x - 15
Os(x) = 120 + 15(x - 1)
Os(x) = 120 - 15(x - 1)
Answers
Answer:
X=104
Step-by-step:
Sorry IF my answer is wrong
Answer:
Os(x) = 120 + 15(x - 1)
Step-by-step explanation:
The total sales will be the sum of the constant 120 copies that were sold in the first hour and the sales in the subsequent hours, represented by the function s(x) = 15(x-1).
Thus, add 120 to the function s(x).

If a truck that is traveling at 15 mph speeds up to 45 mph in 10 seconds, what is the truck’s acceleration?
Answers
Answer:
3miles per hour^2
Step-by-step explanation:
given data
initial speed u= 15mph
final speed v=45mph
time taken t= 10 seconds
Step two:
Required
acceleration a=?
applying the first equation of motion
v=u+at
substitute we have
45=15+a*10
45=15+10a
make a subject of the formula
45-15=10a
30=10a
divide both sides by 10
a=30/10
a=3miles per hour^2

2) 5 gallons and lose 2/3 gallons per minute
2/3 gal/minute minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) 10 gallons when full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
