Answer:
-1/4
Step-by-step explanation:
Since there is a positive and negative sign next to each other it would automatically become a negative sign so then your equation should be 1/2-3/4 now you would need to find the common denominator since 2 can go into 4 2x the equation would be 2/4-3/4 now you would subtract that to get -1/4

Answer:
132 units²
Step-by-step explanation:
The figure is a trapezoid, so its area can be found using the formula for the area of a trapezoid.
A = 1/2(b1 +b2)h
The top "base" is the difference between 21 units and 9 units, so is 12 units. Filling in the numbers, we have ...
A = 1/2(21 units +12 units)(8 units) = 132 units²
The area of the figure is 132 square units.

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

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

Step-by-step explanation: Its not A cuz 7 is a decimal, its not B because of there being 2 p's and same for D
Answer:
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
2.14 = 2.14
