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.
240 is the missing term in the pair of equivalent ratio
Answer:
D
Step-by-step explanation:
To obtain f(g(x)) substitute x = g(x) into f(x), that is
f(10 - 5x)
= (10 - 5x)² + 5 ← expand (10 - 5x)²
= 100 - 50x - 50x + 25x² + 5 ← collect like terms
= 25x² - 100x + 105 → D
Answer:
1 17/42.
Step-by-step explanation:
Find the common denominator, which is 42.
So change -4 1/6 to -4 7/42.
And change 5 4/7 to 5 24/52.
So add -4 7/42 + 5 24/52 and you'll get: 1 17/42.
(The decimal form of this is 1.404762)
