Answers
Step-by-step explanation:
(2x - 3) + 8x = 180 (linear pairs)
10x - 3 = 180
10x = 180 + 3
10x = 183
x = 183÷10
x = 18.3
1 = 2x - 3
2 × 18.3 - 3
= 33.6
2 = 8x
8 × 18.3
146.4
Angle 1 + Angle 2 = 180
33.6. + 146.4. = 180

Find the surface area of the cube
Answers
Answer:
24 cm²
easy way to find surface area of a cube.
use the formula: 6a²
[tex]\hookrightarrow 6(2)^2[/tex]
[tex]\hookrightarrow 6(4)[/tex]
[tex]\hookrightarrow24[/tex]
We know that:
[tex]\space\ Surface \space\ area \space\ of \space\ cube=\s Area \space\ of \space\ it's \space\ faces[/tex]
This means that:
[tex]\space\ Surface \space\ area = [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)][/tex]
Simplify the expression to find the surface area.
Simplifying the expression:
[tex][(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] \\\\\ [4] + [4] + [4] + [4] + [4] + [4]\\\\ 4[6] \\\\ 24 \space\ cm^{2}[/tex]
Hence, the surface area is 24 cm².

Construct an isosceles triangle with one 70* angle and two 4 inch sides. Is this a unique triangle? Explain why or why not.
Answers
The isosceles triangle has 2 equal sides of 4 inches and a vertex angle measure of 70 degrees, and it is a unique triangle
How to determine if the triangle is unique?The given parameters are:
Triangle type = Isosceles triangle
Side length = 4 inches
Angle measure = 70 degrees
Since the triangle is an isosceles triangle, then the equal angles would be:
Ф = 180 - 2 * 70
Ф = 40
The length (L) of the third side is:
L/2 = 7 * cos(40)
Multiply both sides by 2
L = 14 * cos(40)
L = 10.7
So, the angles in the triangle are 70 and 40 degrees; while the side lengths are 4 and 10.7 inches
See attachment for the figure of the isosceles triangle

D. p + 0.07p
Step-by-step explanation:
Answer choice D is correct because if we were to plug in a variable (e.g. 1 and 2), we would get the same amount when using 1.07p. All the other answer choices either work for only one value or don't work at all.
For example,
1 + 0.07(1) = 1.07(1).1 + 0.07 = 1.07
1.07 = 1.07
2 + 0.07(2) = 1.07(2)2 + 0.14 = 2.14

In the diagram below. ∠A is 50. What is ∠B, and ∠C?
Answers
Given:
∠A = 50°In the diagram given, we can tell that:
∠A and ∠B are a linear pair.∠B and ∠C are a linear pair.This means that:
∠A + ∠B = 180°∠B + ∠C = 180°Step-1: Find ∠B.
∠A + ∠B = 180°=> 50 + ∠B = 180°=> ∠B = 180 - 50=> ∠B = 130°Step-2: Find ∠C.
∠A = ∠C (Vertically opposite angles=> ∠C = 50°∠A+∠B = 180° [Linear pair]
50+ ∠B = 180°
∠B = 180-50
∠B = 130°

The length of a cell phone is 1.81.8 inches and the width is 4.84.8 inches. The company making the cell phone wants to make a new version whose length will be 1.621.62 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answers
Answer: 4.32432 inches
Step-by-step explanation:
This is a simple ratio problem:
we are given the old dimensions:
L x W = 1.818 x 4.848
new = 1.62162 x ?
? = (1.62162 x 4.848)/1.818 = 4.32432
The width of the new phone should be 4.32432 inches

Bananas cost $0.47 per pound and Amanda purchased x pounds. She spent a total of $1.41. Which equation expresses the amount Amanda spent on bananas?
0.47 + x = 1.41
0.47 - x = 1.41
0.47x = 1.41
1.41x = 0.47
Answers
[tex]0.47x = 1.41[/tex]
[tex]x = \frac{1.41}{0.47} = 3[/tex]
x = the number of pounds
so, (.47 ) multiplied by x would equal the total amount she spent
