The answer is B, (-10,-2) , (6,6)
Answer:
127
Step-by-step explanation:
m<PQR and m<RQS are supplementary angles so their sum is 180
3x - 5 + x + 1 = 180 add like terms
4x - 4 = 180 subtract 4 from both sides
4x = 176 divide both sides by 4
x = 44
m<PQR is 3x - 5 replace x with 44
3*44 - 5 = 127
Nicole brought 70 carrot sticks to school.
70% of 100 = 70
Answer:
y = - 
x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = - 4, y = 6, thus
k = 
= 
= -
y = - x ← equation of variation
Answer:
V = 166.4
Step-by-step explanation:
The ratio of lengths of similar figures is the scale factor.
The ratio of the surface areas of similar figures is the square of the scale factor.
The ratio of the volumes of similar figures is the cube of the scale factor.
We don't know the scale factor of the figures, but we know the ratio of the surface areas is 200/135.
That is the square of the scale factor.
Let k = scale factor.
k² = 200/135 = 40/27
The ratio of the volumes is
k³ = [√(k²)]³
k³ = [√(40/27)]³ = 1.80320
V = 300/1.80320
V = 166.4
