20x2= 40 just like 20+20=40
Given:
<span>mantle layer of earth begins about 70 kilometers underneath the surface
</span><span>outer core begins about 2970 kilometers underneath the surface
Since we need to find the position of each layer </span><span>relative to the surface, the surface will serve as the point of origin or 0. Below the surface infers a negative value. So, Mantle layer is -70 km from the surface while outer core is -2970 km under the surface.
Comparing -70 and -2970, -70 has a greater value than -2970. The nearer the number is to the origin or 0, the higher its value.
Comparing the absolute greater value of -70 and -2970, -2970 has a greater absolute value. This is because absolute value is the positive value of the number. Absolute value of -70 is 70 while absolute value of -2970 is 2970. Thus, -2970 has a greater absolute value. </span>
We can use the tangent rule for this problem because the opposite x is unknown and adjacent side 10 is knwon. Since,
Since tan 35°=0.474
Multiplying each sides by 10.
4.74=x
x=4.7 (Rounded to nearest tenth)
Answer:
The GCF of 48 and 64 is 16
Step-by-step explanation:
To figure out GCF, you make a list of all the prime factors, pick out the numbers they have in common, and multiply them together. In this case:
48: 2 x 2 x 2 x 2 x 3
64: 2 x 2 x 2 x 2 x 2 x 2
They have four 2's in common, so you multiply 2 x 2 x 2 x 2 =16

• Parallel lines have equal slopes
• The product of perpendicular slopes = - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = 
x + 3 is in this form
with slope m =
rearrange 20x + 12y = 12 into this form
subtract 20x from both sides
12y = - 20x + 12 ( divide all terms by 12 )
y = - + 1 ← in slope-intercept form
with slope m = -
Neither of the conditions for parallel/ perpendicular slopes are met
Hence the lines are neither parallel/ perpendicular
