Answer:

Yes, Rain is correct

238.5 square inches

Step-by-step explanation:

Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)

= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)

= 43.5 + 3(65)

= 43.5 + 195

= 238.5 square inches

The surface area of the triangular pyramid = 238.5 square inches

The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the net attached:

Surface area = 3(1/2 * 10 * 12) + (1/2 * 10 * 8.7)

Surface area = 223.5 in²

The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

Answer:

All possible values of ∠Y are 76.6° and 103.4°

Step-by-step explanation:

In Δ WXY

∵ x is the opposite side of ∠X

∵ y is the opposite side of ∠Y

→ By using the sine rule

∴ [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]

∵ x = 85 and y = 88

∴ m∠X = 70°

→ Substitute them in the rule above

∴ [tex]\frac{85}{sin(70)}[/tex] = [tex]\frac{88}{sin(Y)}[/tex]

→ By using the cross multiplication

∴ 85 × sin(Y) = 88 × sin(70)

→ Divide both sides by 85

∴ sin(Y) = 0.9728582427

∴ m∠Y = [tex]sin^{-1}[/tex](0.9728582427)

∴ m∠Y = 76.62037845

→ Round it to the nearest tenth

∴ m∠Y = 76.6°

→ The other value of ∠Y is the obtuse angle supplement of ∠Y

∴ m∠Y = 180 - 76.6

∴ m∠Y = 103.4°

∴ All possible values of ∠Y are 76.6° and 103.4°

Answer:

420% of 85 = 357

Step-by-step explanation:

85/x=100/420

(85/x)*x=(100/420)*x       - we multiply both sides of the equation by x

85=0.23809523809524*x       - we divide both sides of the equation by (0.23809523809524) to get x

85/0.23809523809524=x

357=x

x=357

B. The quadrilaterals are all the same size and shape.

Step-by-step explanation:

Lauren was drawing a tower ONLY using SIMILAR quadrilaterals, so since that is, since the quadrilaterals are similar, then they must have the same size and shape.

The statement i.e. true for quadrilaterals should be

B. The quadrilaterals are all the same size and shape.

A quadrilateral refer to the closed shape also it is the type of polygon that comprises of four sides, four vertices, and the four angles. Here the sum of the interior angle should be equivalent to the 360 degrees.

Therefore, we can conclude that the second option is correct.

hence, the rest of the options are wrong.

Answer:

Option A: 0.07c = 1.26 is the correct answer

Step-by-step explanation:

Given that the price of shirt is denoted by c.

Given that the sales tax is 0.07 times of the cost of shirt.

Mathematically it can be written as:

[tex]Sales\ tax=0.07c[/tex]

Now it is also given in the statement that the sales tax is $1.26

Putting this value in the above equation

[tex]1.26 = 0.07c[/tex]

As we have to find the cost, dividing both sides by 0.07

[tex]\frac{1.26}{0.07} = \frac{0.07x}{0.07}\\c = \frac{1.26}{0.07}[/tex]

Hence, we saw that the intermediate equation was: 1.26 = 0.07c

So,

Option A: 0.07c = 1.26 is the correct answer

Answer: A. 0.07 · c = 1.26

Step-by-step explanation:

Sales tax (0.07) x cost (c) = price (1.26)

We want to see which ordered pairs are a solution of the equation:

5x - 2y = 20

The ordered pairs are not given, so I will give a general answer, finding the general form of all the ordered pairs that are solutions.

We start with the equation:

5x - 2y = 20

First, we need to isolate one of the variables, let's isolate y.

2y = 5x - 20

y = (5/2)*x - 20/2

Then we get:

y = (5/2)*x - 10

From this, all the ordered pairs (x, y) that are solutions of this equation are given by:

(x, (5/2)*x - 10)

Then to get the points we just need to replace the "x" with numbers, for example for x = 0 we get the solution:

(0,  (5/2)*0 - 10) = (0, -10)

For x = 1 we get the solution:

(1, (5/2)*1 - 10) = (1, -15/2)

And so on.
