Answer:

62 went in the pie

31 are for snacking

Step-by-step explanation:

124 strawberries

Divide by 4

124/4 =31

1/4 went to the neighbor so 31 went to the neighbor

2/4 went into the pie so 2* 31 = 62 so 62 went into the pie

The total used 31+62 = 93

There were 124, so subtract the ones used

124-93=31

The rest are for snacking

There are 31 left for snacking

They had 31 for snacking. 1/4 which is 31 was given to the neighbor. Which means 62 were used in the pie. So what is left of the strawberries is 31. So 31 were left for snacking. Your answer for the first part of the question was wrong

How to find surface area of a right triangular prism to the nearest whole number?

vovangra [49]

The area of the two triangular bases is
(total base area) = 2×(1/2)bh
= bh
= (10 m)(6 m) = 10·6 m² = 60 m²

The area of the three rectangles making up the remaining faces of the prism is
(total lateral area) = length×base + length×height + length×hypotenuse
= length×(base + height + hypotenuse)
= (16 m)(10 m + 6 m + 11.6 m)
= (16 m)(27.6 m) = 16·27.6 m² = 441.6 m²

Then the surface area of the prism is the sum of these
surface area = total base area + total lateral area
= 60 m² + 441.6² = 501.6 m²
When rounded to the nearest whole number, this is
A) 502 m²

The volume of a box is 80 cubic feet with length x-3 and width x-1 and height x+5. What are the possible values of x? What are t

Kryger [21]

Answer:

the only possible value of x is 5
the dimensions are 2 × 4 × 10

Step-by-step explanation:

The cubic equation ...

(x -3)(x -1)(x +5) = 80

has one real root: x = 5. Using that value for x, the dimensions become ...

length = 5 - 3 = 2

width = 5 - 1 = 4

height = 5 + 5 = 10

The dimensions are (length, width, height) = (2, 4, 10).

_____

We cannot tell the thrust of the problem, since it has only one solution. Perhaps you're supposed to write the cubic in standard form and use the Rational Root theorem to find possible values of x. That form can be found to be ...

(x -3)(x -1)(x +5) -80 = 0

x³ +x² -17x -65 = 0

Descartes' rule of signs tells you there is one positive real root. The rational root theorem tells you possible rational roots are factors of 65:

1, 5, 13, 65

We know that x must be greater than 3 (so all dimensions are positive). Thus possible values of x are 5, 13, 65, and we're pretty sure that 65 is way too large.
