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.

Solve: A = LW/2 for L
Answer:
I think L = W/2A
Step-by-step explanation:
Answer:
A: [tex]L=\frac{2A}{W}[/tex]
Step-by-step explanation:
[tex]A=\frac{LW}{2}[/tex]
[tex]\frac{LW}{2}=A[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}2[/tex]

A grocery store sells a bag of 6 oranges for $4.20. If Ayden spent $2.80 on oranges, how many did he buy?
Answer:
4 bags of oranges
Step-by-step explanation:
First, we need to find out how much each bag of oranges costs so we divide.
$4.20 divided by 6 equals 0.7 which means that each bag of oranges costs $0.70.
Next we need to find out how much Ayden spent on oranges so we divide 0.70 by 2.80
2.80 divided by 0.70 equals 4.
This means that Ayden bought 4 bags of oranges.
Hope this helps!
Answer:
4 oranges
Step-by-step explanation:
First find the unit rate by dividing the price of 6 oranges by the amount of oranges in the bag. So $4.20÷6=0.7. 0.7 is the price of one orange. Since the dollar amount is small I just divided $4.20 by 2 and got $2.10 for three oranges. The question is asking how much he bought for $2.80 so add another .70 which is one more orange therefore he bought 4 oranges for $2.80

In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.
Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth
Answer:
2 m/ s
a = F / m
a= 7.92 / 3.6
ie . 2.2 m/ s
Answer:
Step-by-step explanation:
1st step is by rearranging the formula
F=ma
M=f/a
A=f/m
2nd step is use the acceleration formula
A=f/m (acceleration=force divided by mass)
3rd step answer the question using the formula
A=?
F= 7.92N
M=3.6Kg --- 3600g (optional)
A=7.92/3600= 0.0022N/g or 7.92 / 3.6= 2.2N/Kg
4th step turning them to the nearest tenth
0.0022N/g= 0.0N/g or 2.2N/Kg= 2.2N/kg
DONE
TO SEE IF THE ANSWER IS CORRECT USE THE F=MA formula
