The formula to find the surface area of a rectangular prism is SA = 2ab + 2bc + 2ac, where a, b, and c all equal one side of the prism.

To solve this, plug in the value for surface area and the values of the known sides. let’s say a = 3cm and b =5cm and c = y cm. It doesn’t matter with value gets assigned to which letter.

SA = 2ab + 2bc + 2ac
158 = 2(3)(5) + 2(5)(y) + 2(3)(y)
158 = 30 + 10y + 6y
158 = 30 + 16y
128 = 16y
y = 8 cm

What is a fraction?

Fraction is the numeral that is got by the division of the numerator by the denominator. Fraction s a rational number.

Given here the expression is minus 18, start fraction, 9, divided 17, end fraction, plus, left parenthesis, minus, 18, start fraction, 9, divided, 17, end fraction, right parenthesis

We have to first convert this long expression into a mathematical expression

The first expression is minus 18, start fraction, 9, divided 17, end fraction

by converting this into mathematical expression it will be

-18 9/17

The second expression is  left parenthesis, minus, 18, start fraction, 9, divided, 17, end fraction, right parenthesis

by converting this into mathematical expression it will be

(-18 9/17)

Then the whole mathematical expression will be

-18 9/17 + (-18 9/17)= -36 9/17= -36.53

Therefore the mathematical expression is -18 9/17 + (-18 9/17). And the value of this expression will be -36.53.

What is the area of the logo?​

Answers

Answer:

[tex]the \: area \: of \: the \: logo \: is \: {91cm}^{2} [/tex]

Step-by-step explanation:

To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.

Area of the square.

To calculate the area of the square you have to calculate the square of one of its sides, following the formula:

[tex]a = {a}^{2} [/tex]

Where "a" is the length of one of its side.

The side length of the square is a=7cm, so its area will be:

[tex]asquare = {7}^{2} \\ asquare = {49cm}^{2} [/tex]

Area of the triangles.

The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.

To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:

[tex]a = \frac{b.h}{2} \\ a = \frac{7.4}{2} \\ a = \frac{28}{2} \\ a = {14cm}^{2} [/tex]

The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:

[tex]atriangles = 3a \\ atriangles = {42cm}^{2} [/tex]

Now that the area of all shape are calculated, you have to add them to determine the area of the logo:

[tex]alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo = {91cm}^{2} [/tex]

Comprimento do arco = 2πr (θ / 360)

Onde r = raio = 3cm

θ = Ângulo em graus = 45 °

Comprimento do arco = 2 × π × 3 (45/360)

Answers

Step-by-step explanation:

2) 212*198 = 41 976

1) 80-37 = 43

9514 1404 393

Answer:

  1. SCR (or PPW). 43 more flavors

  2. GLT. 41,976 notebooks

Step-by-step explanation:

1. Conceptual key: SCR

Lizzy is starting with 37 flavors. She wants a result of 80 flavors, so the change can be computed from ...

  37 + x = 80

  x = 80 -37 = 43

Lizzy needs to create 43 more flavors.

__

Additional comment

This might also be considered to be using the PPW pattern, as both the number she has and the number she creates make up the whole number. The SCR key may better apply to cases where a "rate of change" is involved. There is no rate of change in this problem.

_____

2. Conceptual key: GLT

There are 212 groups of 198 notebooks, so the total is the number of groups times the number in each group.

  (212 boxes)(198 notebooks/box) = 41,976 notebooks

Number of minutes in [tex](5\times \frac{1}{10})[/tex] hours = 30 minutes

Step-by-step explanation:

Number of minutes in 1 hour = 60 minutes

Number of minutes in [tex]\frac{1}{10}[/tex] hours = [tex]\frac{60}{10}[/tex] minutes

                                                   = 6 minutes
