Answer:
For a scientific experiment, a physicist must make sure that the temperature of metal at 0° C gets no colder than -80° C. The physicist changes the metal’s temperature at a steady rate of -4° C per hour. For how long can the physicists change the temperature?
Step-by-step explanation:
C, I remember doing this test
Answer:
x = 63°
Step-by-step explanation:
See the attachment
The measure of the angles in a triangle = 180 . If the sides of a triangle are congruent, then the base angles are equal. So in the triangle with the 72°, you have another angles = 72°. Looking at the same triangle, 72° + 72° + part of the right angle = 180°. Do the math! 72° + 72° = 140°; 180° -144° = 36° (this is the measure of the piece of the right angle that is in the triangle with the 72° angle.. So the other part of the 90°(right angle) = 90° - 36° = 54°.
Now to solve for x: You know that if the sides are congruent in a triangle, then the base angles are equal. Thus this triangle angles are x, x, and 54°.
You know that a triangle = 180°, so x + x + 54° = 180°; 2x +54° = 180°; 2x = 126°; x = 63°
Answer:
30 cm
Step-by-step explanation:
The circumference of a circle is
C = 2*pi*r
60pi = 2* pi *r
Divide each side by 2pi
60/2pi = 2 pi r/ 2pi
30 =r
Answer:
So I’m guessing you want either how to get a name or name ideas?
Step-by-step explanation:
1. Compare the friend’s favorite things and lump them together (lets say one likes ballet and another likes swans so the name would be the Graceful Swans)
2.Pick a name that describes what you like about your friendship (lets say they like the love that the friends give to one another so lets say Loving Friends)
NAME IDEAS
Hunting Pack
Graceful Swans
Cloudy Skies
DREAM TEAM
Windy days
IF YOU WANT TO DIVIDE THE FRIENDS THEN THERE WOULD BE TWO FRIENDS ON EACH TEAM
Hope this helped
