When I multiply 9x9 how would I go about counting by 9s?

Mathematics
1 answer:
11111nata11111 [884]3 years ago
5 0

Answer:

If you're looking for a shortcut, I usually find the number 1 less than what you are multiplying 9 by, this case 8, and then add a number that gets to 9.

So 9x6 would be:

5+4=9

54

Step-by-step explanation:

When multiplying by 9s the product's two numbers added together =9.

Sorry if this is confusing. Hope this helps though.

RideAnS [48]

Something is missing there is no given. But here are the given for this question:

Salary = $8.75 per hour

40 hour work week

52 work week per year

5 days of work per week

Gas mileage is 21 miles per gallon

Gas costs is 1.26 per gallon

Average speed is 45 miles per hour

Daily round trip to work and back home is 34 miles

a. Kevin’s annual salary is 8.75 per hour x 40 hour work week x 52 work week per year

= $18,200

b. Kevin will spend on fuel each week:

34 miles daily round trip x 5 day work week divided by 21 miles per gallon x 1.26 per gallon

= $10.20

c. Kevin will spend _ hours on commuting

= 34 miles is the daily round trip x 5 day work week divided by 45 miles average speed per hour

= 3.78 hours

Hope this helps!

Object A has 50 kg while Object B has 75 kg. They were pushed with the same amount of force. Which will have greater acceleratio
raketka [301]

Answer:

Object A will have greater acceleration.

Step-by-step explanation:

Given that,

The mass of object A = 50 kg

The mass of object B = 75 kg

They were pushed with the same amount of force.

We know that, the force acting on an object is given by :

F = ma

Here F is same for both mass

m_1a_1=m_2a_2

Mass and acceleration have inverse relation. It means the object whose mass is less will have greater acceleration. Hence, the acceleration is greater for object A.

Determine the equation of the following polyromial that passes through point (0,6).
Ostrovityanka [42]

Answer:

Cubic polynomial has zeros at x=−1x=−1 and 22, is tangent to x−x−axis at x=−1x=−1, and passes through the point (0,−6)(0,−6).

So cubic polynomial has double zero at x=−1x=−1, and single zero at x=2x=2

f(x)=a(x+1)2(x−2)f(x)=a(x+1)2(x−2)

f(0)=−6f(0)=−6

a(1)(−2)=−6a(1)(−2)=−6

a=3a=3

f(x)=3(x+1)2(x−2)f(x)=3(x+1)2(x−2)

f(x)=3x3−9x−6

Finding the inverse function for f(x)=1/x^2
Anna [14]

to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

\stackrel{f(x)}{y}=\cfrac{1}{x^2}\implies \stackrel{\textit{quick switcheroo}}{x=\cfrac{1}{y^2}}\implies y^2=\cfrac{1}{x}\implies y=\sqrt{\cfrac{1}{x}}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{1}{\sqrt{x}}
