Answer:
Let the additional weight that can be added be = x
Current weight of the bag = 38 pounds
Total weight can be = 50 pounds
The equation becomes:
38+x < or equal 50
x < or equal 50-38=12
Hence, a weight of 12 pounds cab be added to the current wight.

A triangular pyramid and its net are shown. Rain uses the calculations below to conclude that the surface area of the triangular pyramid is 238.5 square inches. 3 x 10 x 13) + ( x 10 x 8.7) 3 (65) + 43.5 238.5 Is Rain correct? Use the drop-down menus to explain your reasoning.
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.
What is an equation?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.

Sales tax on a shirt is 0.07 times the cost of the shirt. The sales tax for a shirt is $1.26. Which equation could you use to find the cost, c, of the shirt before sales tax? A. 0.07 · c = 1.26 B. 0.07 · 1.26 = c C. 0.07 ÷ 1.26 = c D. 0.07 ÷ c = 1.26
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)

which of the ordered pairs is a solution of the following equation
5x-2y=20
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.

In ΔWXY, y = 88 cm, x = 85 cm and ∠X=70°. Find all possible values of ∠Y, to the nearest 10th of a degree.
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°

what you find 420% of 85 what are you looking for?
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

O The quadrilaterals have corresponding angles that are congruent.
0 The quadrilaterals are all the same size and shape.
O The quadrilaterals are different shapes but the same size.
O The quadrilaterals have corresponding sides that are congruent.
Answer:
B. The quadrilaterals are all the same size and shape.

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.
What are quadrilaterals?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.
