Answer:

1. Changing speed. It does not stay constant instead it changes speed.

2. 1.86

Step-by-step explanation:

You would find how much it multiples by on the chart to the left and find its never the same number which would make it change speed but also for number 2 you would put all the numbers in order that you have gotten and the middle number would be your average.

Given:

In the diagram given, we can tell that:

This means that:

Step-1: Find ∠B.

Step-2: Find ∠C.

∠A+∠B = 180° [Linear pair]

50+ ∠B = 180°

∠B = 180-50

∠B = 130°

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:

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.

Answer:

16 oz of water

Step-by-step explanation:

if you multiply 3 by 4 its 12 if you multiply 4 by 4 its 16

The isosceles triangle has 2 equal sides of 4 inches and a vertex angle measure of 70 degrees, and it is a unique triangle

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

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

Answer:

=> The third side of the triangle is √53 mm

Step-by-step explanation:

We know that this is a right angled triangle ,

so , by using Pythagoras theorem we can find out the third side of the triangle ,

=> P²+B²= H²

=> 7²+2² = H²

=> 49+4 = H²

=> 53 = H²

=> √53 = H

The third side of the triangle is √53mm

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 = 1.07

        1.07 = 1.07

       2 + 0.14 = 2.14

       2.14 = 2.14
