Answer:
62 nickels and 17 quarters
Step-by-step explanation:
62x0.5=3.10
17x0.25=4.25
4.25+3.10=7.35
x is 53
angle PQD is equal to APQ. so its 62 degrees
PRC and PRD are supplement so their sum is 180.
PRD=115 PRC= 180 -115= 65
the sum of the angles of a triangle is equal to 180. so:

good luck
Answer:

Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form:
where <em>m</em> is the slope and <em>b</em> is the y-intercept.
Perpendicular lines always have slopes that are negative reciprocals (ex. 1/2 and -2, 3/4 and -4/3)
<u>Determine the slope (</u><em><u>m</u></em><u>):</u>

Rearrange into slope-intercept form:

Now, we can identify clearly that the slope is -2. Because perpendicular lines always have slopes that are negative reciprocals, a perpendicular line would have a slope of
. Plug this into
:

<u>Determine the y-intercept (</u><em><u>b</u></em><u>):</u>

Plug in the given point (1,3) and solve for <em>b</em>:

Therefore, the y-intercept is
. Plug this back into
:

I hope this helps!
Answer:
Step-by-step explanation: mass of sheep=6 x 10 kg
mass of ant= 3 x 10 kg
=6 x 10=60, 3 x 10=30
60/30=20
therefore in standard form
20=2 x 10
ans: 2 x 10 kg
The sheep weighs 2x10kg more than the ant.
Answer:
8 l
Step-by-step explanation:
1 l = 1000 mm
8000 mm = 8000/1000
8000 mm = 8 l
