Answer:
Option (a).
Step-by-step explanation:
The value of y varies directly with x. It would mean that,
y=kx, where k is constant
When
[tex]y=2\dfrac{4}{7},x=\dfrac{3}{7}\\\\y=\dfrac{18}{7}, x = \dfrac{3}{7}[/tex]
then,
[tex]\dfrac{18}{7}=k\times \dfrac{3}{7}\\\\k=6[/tex]
When x = 27,
[tex]y=6\times \dfrac{2}{7}\\\\y=\dfrac{12}{7}\\\\\text{or}\\\\y=1\dfrac{5}{7}[/tex]
So, the value of y is [tex]1\dfrac{5}{7}[/tex] when x is 27.
Write an equation that you can use to find the number of refills Keith bought. A restaurant sells a coffee refill mug for $6.75. Each refill costs $1.25. Last month Keith spent $31.75 on a mug and refills. (use x for your variable and do not use $ in your answer) *
Answer:
6.75+1.25x=31.75
Step-by-step explanation:
let x be the number of refils
also given is that the cost of one refill is $1.25
hence the total refil will be 1.25x
given that the cost of a mug is $6.75
6.75+1.25x=31.75
therefore the expression that can be used to solve for the number of refills is
6.75+1.25x=31.75

What is the sum of zeros in this equation (m-10)(8m-1)=0? Ente4 your ancwer as a fraction. PLSSS I RLLYYY NEEDD HELPP
Answer:
10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]
Step-by-step explanation:
Given
(m - 10)(8m - 1) = 0
Equate each factor to zero and solve for m
m - 10 = 0 ⇒ m = 10
8m - 1 = 0 ⇒ 8m = 1 ⇒ m = [tex]\frac{1}{8}[/tex]
Thus sum of roots = 10 + [tex]\frac{1}{8}[/tex] = 10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]
How many years will it takes an investment of 3000$ to amount to 5,000 if money is invested at 4.1% compounded monthly
Answer:
1.66
Step-by-step explanation:
The years needed to make $3000 to $5000 is 12.5.
What is compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, an investment of $3000 to amount to 5,000 if money is invested at 4.1% compounded monthly
A = P(1+r/12)^12t
5000 = 3000(1+0.041/12)^12t
5/3 = (1.0034)^12t
Taking log both sides,
log5/3 = 12tlog(1.0034)
0.221 = 12t0.00147
12t = 150.34
t = 12.5
Hence, required years are 12.5.
