What unit is used to measure the density of a solid??
Answers
Answer:
Grams per cubic meter or g/cm3
Step-by-step explanation:
The answers vary, but they have the same format which is
density = mass/volume
For instance, if the mass is in grams and the volume is in cubic centimeters, then the density would be in grams/cm^3, where "cm^3" is the abbreviation of "cubic centimeters". We can read "grams/cm^3" out as "grams per cubic centimeter"

(c) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm. There exist two circles of center A and tangent to (c). Construct these circles; calculate their radii
Answers
Given :
C) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm.
There exist two circles of center A and tangent to (C).
To Find :
The radius of the new circles.
Solution :
Since, OA is 3 cm .
So, first circle with tangent to C if centre is at A is OA itself.
First radius, r = 3 cm.
And second circle is the on with radius , R = 3 + 2 = 5 cm.
Therefore, the radius of both the circles are 3 cm and 5 cm.
Hence, this is the required solution.

On the coldest day of the year, the temperature at noon was 11℉. By midnight, the temperature had decreased by 15.5℉. What was the temperature at midnight? *
Answers
Answer: -4.5 ℉
Step-by-step explanation:
Given: On the coldest day of the year, the temperature at noon = 11℉
By midnight, the temperature had decreased by 15.5℉.
i.e. The temperature at midnight = Temperature at noon - 15.5℉
= 11℉ - 15.5℉
= (11-15) ℉
= -4.5 ℉
Hence, the temperature at midnight was -4.5 ℉.

When finding the slope of the trend line, what does the slope mean about the data of the scatterplot? Explain.
Answers
Answer:
So the slope on a scatterplot is almost always an estimate, so its not exact. It is just an estimate on where it might go and what might happen t data in the future.
Answer:
The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.

In the accompanying diagram of a parallelogram
ABCD ,DC= 5x-18, BC=3x-6, AB=2x+12 find measure BC. Please help
Answers
Answer:
BC = 39
Step-by-step explanation:
Given:
DC = 5x - 18,
BC = 3x - 6,
AB = 2x + 12
Opposite sides of a parallelogram are equal.
Therefore:
AB = DC
2x + 12 = 5x - 18
Collect like terms
12 + 18 = 5x - 3x
30 = 2x
Divide both sides by 2
15 = x
x = 15
BC = 3x - 6
Plug in the value of x
BC = 3(15) - 6 = 45 - 6
BC = 39

Step-by-step explanation:
brainliest please
Answer:
x=-4, Give brainliest please
Step-by-step explanation:
Step 1: Add 8.4x to both sides.
2.1x+45.2 = -8.4x +3.2
+8.4x +8.4x
10.5x+45.2=3.2
Step 2: Subtract 45.2 from both sides.
10.5x + 45.2 = 3.2
-45.2 -45.2
10.5x=−42
Step 3: Divide both sides by 10.5.
[tex]\frac{10.5x}{10\\}[/tex]=[tex]\frac{-42}{10}[/tex]
