Answer:
10x-20
Step-by-step explanation:
Answer:
the answer is the same as D 124 degrees
Step-by-step explanation:
The sides of the triangle occur in a ratio of 4 : 7 : 2, so if <em>x</em> is some positive number, then we can write each side's length in terms of <em>x</em> as 4<em>x</em>, 7<em>x</em>, and 2<em>x</em>.
The perimeter is 299 yd, so
4<em>x</em> + 7<em>x</em> + 2<em>x</em> = 299 yd
13<em>x</em> = 299 yd
<em>x</em> = (299 yd) / 13
<em>x</em> = 23 yd
Then the sides of the triangle have lengths of
4<em>x</em> = 4 • 23 yd = 104 yd
7<em>x</em> = 7 • 23 yd = 161 yd
2<em>x</em> = 2 • 23 yd = 46 yd
"Median" here refers to the side length between the shortest and longest sides, so the answer would be 104 yd.
Answer:
Variable d represents the time per minute Lilianna spends in the park.
Step-by-step explanation:
Lilianna uses
calories per minute just by sitting. She uses 1 more calorie per minute by walking.
Liliana uses a total of
calories walking to the park.
Lilianna uses the equation,
to represent the situation.
Here, variable d represents the time per minute she spends in the park.
and is given as,

It can be written as,

Solving for d,





Thus, she spend d= 7 minutes total to the park.
