Answer:
A. 4.40 square units
Step-by-step explanation:
The triangle is isosceles with base angles of 70°. The a.pex angle will be ...
180° -2(70°) = 40°
The area of a triangle can be computed from two sides and the angle between them as ...
A = (1/2)ab·sin(γ)
A = (1/2)(3.7)(3.7)sin(40°) ≈ 4.40 . . . square units
There are 10 cards. They are numbered: 9,10,11,12,13,14,15,16,17,18. One card is randomly picked. What is P(prime number)? 20%,3

So there are 10 numbers, and 3 of them are prime. Our prime numbers are 11, 13, and 17.
3/10 would be our fraction for this equation, and 3/10 is equal to 30%.
30% is your answer!
Answer:
A. One solution.
B. x = 3.
Step-by-step explanation:
4(2x - 5) = 4
4*2x + 4*-5 = 4
8x - 20 = 4
8x = 24
x = 3.
Answer:
y = 1/2x - 4
Step-by-step explanation:
The x-intercept is when y = 0, so it would be:
-x + 2 * 0 = 4
-x = 4
x = -4
That means the x-intercept is (0, -4)
The parallel line would have the same slope as this one, so:
The parallel line has a slope of 1/2
So now you need to find the equation of a line that has a slope of 1/2 and passes through the point (0, -4)
Put it in point slope form:
y - (-4) = 1/2(x - 0)
y + 4 = 1/2x
y = 1/2x - 4
