Answer:
Part 1) The equation for the monthly charges for Runfast is and for BA&D is
Part 2) The solution of the system of equations is the point (1.75.22)
Step-by-step explanation:
Let
x -----> the number of gig of data
y -----> the total monthly charges
we know that
<em>Runfast Company</em>
-----> equation A
<em>BA&D Company</em>
-----> equation B
Part 2) Use your mathematical skill to solve this system of equations using the substitution method
we have
-----> equation A
-----> equation B
Substitute equation B in equation A and solve for x
Find the value of y
so
The solution is the point (1.75.22)
That means
For the number of gig equal to 1.75 the monthly charge is equal to $22 in both company's
therefore
For a number of gigs less than 1.75 the company Runfast has the better pricing, while for a number of gigs greater than 1.75 the company BA&D has the better pricing
Answer:
a)1017.88 cm³
b)63.62 cm² (corr. to 2 d. p.)
c)452.39 cm² (corr. to 2 d. p.)
d)579.63 cm²
Step-by-step explanation:
a) Volume = π x r x h = π x (9/2) x 16 = 1017.88 cm³
b) area of tin is used = circle = π x (9/2)² = 63.62 cm² (corr. to 2 d. p.)
c) area of cardboard is used = 2 x π x (9/2) x 16 = 452.39 cm² (corr. to 2 d. p.)
d) total area surface = 2(63.62) + 452.39 = 579.63 cm²
Answer:
11
Step-by-step explanation:
We can have any. two numbers that represent a and b
It CANT BE THIS FOLLOWING
A AND B CANT BE ZERO SO WE CAN USE MULTIPLES OF 10
A CANT BE EQUAL TO B SO WE CANT USE MULTIPLES OF 11( ALL THE WAY UP TO 99 BUT WE CANT USE ANY NUMBER AFTER THAT SINCE NUMBERS THAT COME AFTER 99 ARE THREE DIGIT NUMBER)
<em>Let</em><em> </em><em>use</em><em> </em><em>5</em><em> </em><em>and</em><em> </em><em>6</em><em>.</em>
<em>5</em><em>6</em>
<em>Reverse</em><em> </em><em>the</em><em> </em><em>digits</em><em> </em>
<em>6</em><em>5</em><em> </em>
<em>add</em><em> </em><em>56</em><em> </em><em>to</em><em> </em><em>6</em><em>5</em><em> </em>
121
Divide this by 6+5=11
The answer is 11 This vary for all answers let use 1,7
17 then reverse
71 then add 71 and 17
88 then divide by 1+7=8
11
