The given equation, x9 - 5x3 + 6 = 0, is not a quadratic equation because the exponent of the first term is 9 while that of the second term is 3. The square of 3. If we are to square x3, we should only be getting x6 instead of x9. Therefore, the answer is NO.
Answer: Van: 10, Bus: 46
Step-by-step explanation:
Let the number of students in each van be represented by v.
Let the number of students in each bus be represented by b.
The question given can be formed into an equation as:
3v + 13b = 628 ...... i
9v + 2b = 182 ......... ii
Multply equation i by 9
Multiply equation ii by 3
27v + 117b = 5652 ........ iii
27v + 6b = 546 ....... iv
Subtract iv from iii
111b = 5106
b = 5106/111
b = 46
Bus = 46
Recall that 9v + 2b = 182
9v + 2(46) = 182
9v + 92 = 182
9v = 182 - 92
9v = 90
v = 90/9
v = 10
Van = 10
Answer:
Option B
Step-by-step explanation:
The reason is because the surface area is not including the base of the pyramid and the top of the prism.
Option b. she left out one of the faces of the solid she should have simplified 2((5)(7))+2((6)(7))+2[1/2(5)(9.3)]+2[1/2(6)(9.2)]+(5)(6)
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the surface area of the pyramid not including the base plus the surface area of the prism not including the top
so
SA= 285.7 units squared
Answer:
$125
Step-by-step explanation:
You can write an equation from the problem statement:
$80 = 0.64 × (total cost)
This is solved by dividing by 0.64.
$80/0.64 = $125 = (total cost)
_____
Of course, you know that ...
64% = 64/100 = 0.64
Both fractions are read as "sixty-four hundredths."
