Answer:
The width is .16 miles and the length is .3 miles
Step-by-step explanation:
Use the area formula for a rectangle and the fact that the length = .14 + w. Your formula will look like this then:
.048 = w(.14 + w)
Distribute through the parenthesis to get
![.048=.14w+w^2](https://tex.z-dn.net/?f=.048%3D.14w%2Bw%5E2)
Get everything on one side of the equals sign and set the whole equal to 0:
![0=w^2+.14w-.048](https://tex.z-dn.net/?f=0%3Dw%5E2%2B.14w-.048)
Let's multiply everything by 1000 to get rid of those decimals:
![0=1000w^2+140w-48](https://tex.z-dn.net/?f=0%3D1000w%5E2%2B140w-48)
Now we need to factor that to solve for w:
w = .16 and w = -.3
Since the two things in math that will never ever be negative are distance measures and time, we can safely disregard the -.3. That means that the width is .16 and the length is ,16 + .14 which is .3. There you go!
Answer: The value of the gift certificate is $140.
Step-by-step explanation:
Let the worth of gift certificate be 'x'.
Number of families = 4
Amount that each family is contributing = $35
According to question, we need to write a division equation:
![\frac{x}{35}=4\\\\x=35\times 4\\\\x=\$140](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B35%7D%3D4%5C%5C%5C%5Cx%3D35%5Ctimes%204%5C%5C%5C%5Cx%3D%5C%24140)
So, the value of the gift certificate is $140.
If the next month is march, then this month is february.
Answer:
Yes they are similar
Step-by-step explanation:
They have the same measurements adding up to 180.
Triangle RST angles are 120, 20, and 40
Triangle JKL angles are 120, 40, 20
Those are the same numbers.
