Y e s .
Using the Distance formula and all.
If functions transfer some a to b via some formula, then inverse of such functions transfer b to a via some other formula.
Hope this helps.
Answer:
![6\frac{7}{8}\ miles](https://tex.z-dn.net/?f=6%5Cfrac%7B7%7D%7B8%7D%5C%20miles)
Step-by-step explanation:
Given that Lil's distance in 2/5 hrs is 2 3/4hrs
-Let x be the distance ran in 1 hr.
#We equate and cross multiply to solve for x as follows:
![\frac{2}{5}\ hrs=2\frac{3}{4}\\1\ hr=x\\\\\therefore x=2\frac{3}{4}/\frac{2}{5}\\\\=6\frac{7}{8}\ miles](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%5C%20hrs%3D2%5Cfrac%7B3%7D%7B4%7D%5C%5C1%5C%20hr%3Dx%5C%5C%5C%5C%5Ctherefore%20x%3D2%5Cfrac%7B3%7D%7B4%7D%2F%5Cfrac%7B2%7D%7B5%7D%5C%5C%5C%5C%3D6%5Cfrac%7B7%7D%7B8%7D%5C%20miles)
Hence, Lil can run 6 7/8 miles in 1 hr.
Answer:
312.38
Step-by-step explanation:
first get the area of the circle which will be 490.625 then subtract the rectangle to get the round area with grass-290.625
then in that square there is a triangle covered with grass so get the area of the triangle-22.75 then add the area of the triangle to the rounded part with grass
Answer:
See below ~
Step-by-step explanation:
Sides of a rhombus are equal.
⇒ QT = TS
⇒ x² - 4x - 10 = 6x + 14
⇒ x² - 10x - 24 = 0
⇒ x² + 2x - 12x - 24 = 0
⇒ x (x + 2) - 12 (x + 2) = 0
⇒ (x + 2)(x - 12) = 0
⇒ x = -2 or x = 12
Substitute both values and see which gives a positive value for QT :
<u>When x = -2</u> :
- QT = (-2)² - 4(-2) - 10
- QT = 4 + 8 - 10
- QT = 2
<u>When x = 12</u> :
- QT = (12)² - 4(12) - 10
- QT = 144 - 48 - 10
- QT = 86
The 2 possible answers are :
- x = -2, QT = 2
- x = 12, QT = 86
