Answer: a ≤ 4 or (-∞, 4]
Step-by-step explanation:
Here we have the inequality:
4a ≤ 16
this means that the left sides is less or equal than the right side.
First, find the equal part:
4*a = 16
a = 16/4 = 4
So the maximum possible value of a is 4.
Now, all the values of a smaller than 4 also make the inequality true (even the negative values) so the possible values of a are:
a ≤ 4 or (-∞, 4]
Answer:
77°
Step-by-step explanation:
Angles on a straight line add up to 180
180 - 103 = b
180 - 103 = 77
Answer: For number 3 it's 8 for number 5 is 32.
Step-by-step explanation: Remember length times width times height (L*W*H) is the rule to find the area of a cuadrilateral
Answer:
a) If the diameter is 400 feet wide, then the radius is half that, which is 200 feet wide.
b) The circumfernce is π times the diameter, which is 400 feet. 400×π≈1256.64
c) She is not correct. She squared 400, which is 160000, when she should have squared 200, which is 40000. Then, multiply by π.
40000 × π ≈ 125663.7
Step-by-step explanation:
remember, the area of a triangle is
baseline × height / 2
so, for this one the area is
13 × 4 / 2 = 13×2 = 26 ft²
