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

In the diagram below. ∠A is 50. What is ∠B, and ∠C?

Answers

Solution:

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°

Given :

∠A = 50°

Solution :

∠A= ∠C [Vertically opposite angles]∠C = 50°

∠A+∠B = 180° [Linear pair]

50+ ∠B = 180°

∠B = 180-50

∠B = 130°

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

Answers

Answer:

7.5 hrs.

Step-by-step explanation:

First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b

Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]

y = mx + b

y = 17.7x + b

I will be using (4, 70.80) to find the value of b

(4, 70.80)

y = 17.7x + b

70.80 = 17.7(4) + b

70.80 = 70.80 + b

-70.80  -70.80

0 = b

y = 17.7x + b ==> y = 17.7x + 0 =  OR  y = 17.7x (since the value of b is 0)

The question wants us to find out how long it took Magan to make $132.75

y = 17.7x

132.75 = 17.7x

/17.7        /17.7

7.5 = x

This means that it took him 7.5 (seven and a half) hours to make $132.72

Answer: I would say C

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
