<span>the formula d = rt
</span><span>
r = d/t (</span>c. d over t = r<span>)
</span>t = d/r (a. d over r = t)
d = rt (<span>d. d over rt = 1)
</span><span>
so answer
</span>b. r = dt ......not equivalent to the formula d = rt
Answer:
They are congruent, this is because both shapes are the same size and have the same angles as show with the lines at the edges. I believe it's AAS

Hoped this helped!
Answer:
x = √7
Step-by-step explanation:
First find the missing angle of the triangle with the side as 5, and the hypotenuse as 6.
a² + b² = c²
5² + b² = 6²
25 + b² = 36
b² = 11
b = √11
So now we know that for the triangle with sides 2 and x, the hypotenuse is √11. Now use the Pythagorean Theorem to find x.
a² + b² = c²
2² + x² = (√11)²
4 + x² = 11
x² = 7
x = √7.
Answer:
[-7, ∞ )
Step-by-step explanation:
I'm assuming that the function is y = (x + 8)² - 7
To find the range, we need to find the vertex,
Vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the location of the vertex. Our equation has a = 1, h = -8, and k = -7. Since a > 0, the parabola opens up, so the upper limit of the range is infinity. To find the lowest value of the range, we find the vertex.
Here the vertex is at point (-8, -7), so -7 is the lower limit of the function's range.
The range is [-7, ∞ )
Answer:
Step-by-step explanation:
L = B + 5
2L + 2B = 150
Substituting gives 2B + 2(B+5) = 150
4B = 140
B=35; L = 40
Area = B x L = 35 x 40 = 1400 m2
