Answer:
length 60 feet
length 2=60 feet
width 1=30feet
width 2=30feet
those is because there is 4 sides to a rectangle
Step-by-step explanation:
because the length is twice the width, 2x 30=length
Answer:
Option (C)
Step-by-step explanation:
In the given circle, AB is a chord passing through the center O.
Therefore,chord AB is a diameter of the circle and OC is the radius.
AO = OB = OC
OC⊥AB, and length of OC = 7 cm
By applying Pythagoras theorem in right ΔBOC,
BC² = OC² + OB²
BC = ![\sqrt{OC^{2}+OB^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7BOC%5E%7B2%7D%2BOB%5E%7B2%7D%7D)
= ![\sqrt{7^2+7^2}](https://tex.z-dn.net/?f=%5Csqrt%7B7%5E2%2B7%5E2%7D)
=
≈ 9.9 units
Therefore, Option (C) will be the answer.
Total money Marcus has = $28
Money spent to buy a notebook = $3.75
Money left now = ![28-3.75=24.25](https://tex.z-dn.net/?f=28-3.75%3D24.25)
Money needed to be saved = $11.25
So, the amount of money Marcus can spend = ![24.25-11.25=13](https://tex.z-dn.net/?f=24.25-11.25%3D13)
Cost of a packet of chips = $1.30
The inequality to determine the maximum number of chips he can buy is:
Let the number of chips Marcus can buy = x
As he cannot spend more than $13 to buy chips so equation becomes:
![1.30x\leq 13](https://tex.z-dn.net/?f=1.30x%5Cleq%2013)
Solving this we get
![x\leq 10](https://tex.z-dn.net/?f=x%5Cleq%2010)
Hence, Marcus can buy a maximum of 10 packs of chips and save $11.25
Answer:
Yes
Step-by-step explanation:
You can check whether the ratios form a proportion, by setting one piece of the ratios as x
Thus, we can use the equation 4/3.2=22/x.
From this, we get 4x=70.4.
Solving for x gives us 17.6.
