Given that the temperature is at 86 F, for us to know if Tom will have an extra break we need to convert this into Celsius;
f=1.8c+32
86=1.8c+32
making c the subject we getL
86-32=1.8c
54=1.8c
thus;
1.8c=54
hence;
c=54/1.8
c=30
since the temperature is 30 Celsius which is less than 32 Celsius it implies that Top won't go for extra brake.
Answer:
x = $0.50
y= $0.75
Step-by-step explanation:
1. Multiply the equations to have the same coefficients
5(6x + 6y = 7.5) → 30x + 30y = 37.5
3(10x + 5y = 8.75) → 30x + 15y = 26.25
2. Subtract the equations
30x + 30y = 37.5
<u>- 30x + 15y = 26.25</u>
15y = 11.25
3. Solve for y by dividing both sides by 15
y = 0.75
4. Plug in 0.75 for y into one of the equations
6x + 6(0.75) = 7.5
5. Simplify
6x + 4.5 = 7.5
6. Solve for x
6x = 3
x = 0.5
Answer:
A. the slope of the best fit line would be negative
Answer:
The minimum number of faces a polyhedron can have is 4 faces.
Step-by-step explanation:
We know that a polyhedron is a shape surrounded by polygons. We also know that we need at least 3 sides to make a polygon. So, at the minimum a polyhedron can be made by using only triangular faces but in order to make a closed figure we need at least four triangular faces (which is a tetrahedron).
Answer:
y-2 = -2/3 (x+8)
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
m= (-4-2)/(1--8)
= (-6)/(1+8)
=-6/9
=-2/3
point slope form
y-y1 = m(x-x1)
y-2 = -2/3(x--8)
y-2 = -2/3 (x+8)
