Answer:
Angles on a straight line add up to 180°
Therefore, the interior angle D of the triangle = 180 - 150 = 30°
Draw a horizontal line of 8 cm - label DE.
Measure an angle of 30° from point D and draw a line.
Measure an angle of 90° from point E and draw a line.
These 2 lines will intersect at point F.
Erase the part of the lines that extend past the point of intersection.
Answer:
6x - 5 ≥ 8
Step-by-step explanation:
Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?
The inequality sign of
a) At least = greater than or equal to = ≥
Let us represent the number as = x
Hence: "five less than the product of a number and 6 is at least 8" can be written as:
= x × 6 - 5 ≥ 8
= 6x - 5 ≥ 8
Answer:
Step-by-step explanation:
So just divide the areas by the length:
And that is your width.
Answer:
21 minutes divided by 7 walls = 3 minutes per wall for 5 people.
Assuming each worker has the same exact productivity, one person would take 15 minutes to paint a single wall (3 minutes x 5 people to get the amount of time for 1 worker per wall).
15 minutes for one worker multiplied by 5 walls = 75 minutes for one worker. Divide 75 minutes by 3 people = 25 minutes to paint all 5 walls with 3 people.
Step-by-step explanation:
Triangular prism
length of slanted side:
sqrt(3^2 + 4^2) = 5
SA = 2(1/2)(8)(3) + 8(12) + 2(5)(12) =240
V = (1/2)(8)(3)(12) = 144
cuboid
SA = 2(7x6) + 2(7x5) + 2(6x5) = 214
V = 7x6x5 = 210
