Answer:
4.4 degrees C.
Step-by-step explanation:
C = 5/9 (F - 32)
When F = 40:
C = 5/9( 40 - 32)
= 5/9 * 8
= 40/9
= 4.4 degrees C,
Answer:
Volume = 128
Surface area = 179.2
Step-by-step explanation:
The figure appears to be a square pyramid
The volume of a pyramid can be calculated using the formula : a²(h/3)
where a = base length and h = height
Here the base length appears to be 8 and the height appears to be 6
So we have V = a²(h/3) and a = 8 and h = 6
==> plug in values
V = 8²(6/3)
==> evaluate exponent
V = 64(6/3)
==> divide 6 by 3
V = 64(2)
==> multiply 64 and 2
V = 128
Formula for surface area of a square pyramid is SA = a² + 2al
where a = base length and l = slant height
Looking at the pyramid the slant height appears to be 7.2 and the base length is 8
so we have SA = a² + 2al and a = 8 and l = 7.2
==> plug in values
SA = 8² + 2(8)(7.2)
==> evaluate exponent
SA = 64 + 2(8)(7.2)
==> multiply 2, 8 and 7.2
SA = 64 + 115.2
==> add 64 and 115.2
SA = 179.2
Answer:
x=-1
Step-by-step explanation:
The sum of the interior angles of all triangles is 180 degrees. This is a right triangle, thus we know two interior angle values (90 degrees and 29 degrees). To find the third, set the sum of all interior angle values equal to 180 and solve for g.
180 = 90 + 29 + g
Collect like terms.
180 = 119 + g
Subtract 119 from both sides.
61 = g
Find the sum using 61 for g to check work.
180 = 90 + 29 + g
180 = 90 + 29 + 61
180 = 180
