the glass has a length of 8 units and a scale of 2.5 cm what is the height

Answer:

1. -10

2. -11

Step-by-step explanation:

Answer:

From the given figure we can see that :---

MN||PO, MN=PO and MP=NO

Therefore, angle M=angle N (adjacent sides of the trapezoid)

[tex](8x - 16) = (6x + 20) \\ 2x = 36 \\ \boxed{x = 18}[/tex]

angle M=angle N= (6×18)+20=108+20 =128°

angle O =(180°-128°)=52°

Answer:

it basically means that the order in how you multiply doesnt matter. so wether u type 5 x 4 or 4 x 5 in ur calculator, you'll get the same answer either way. this works for when you want to multiply and divide, but not when you wanna subtract or divide.

Step-by-step explanation:

its basically a property that says that if you wanna swap the numbers/variables that are on one side of this specific type of equation (multiplication and addition), you can!

Answer:

yooo

Step-by-step explanation:

the communitive property  is when you have the same number or same equation but just reverse it. For example, (5x+67) with the communitive property could be (67+5x). Its just the equation you are given but reversed and since they are the same numbers, you will get the same answer either way you do the problem, hope this helps you lol.

(x^2 - 5x^2 + 4x) / 2x + 8

Step-by-step explanation:

(x^2 - 16) / 2x + 8 * (x^3 - 2x^2 + x) / (x^2 + 3x -4)

(x^5 - 2x^4 - 15x^3 + 32x^2 -16x) / 2(x - 1)(x + 4)(x + 4)

x(x-1)(x-1)(x+4)(x-4) / 2(x - 1)(x + 4)(x + 4)

Answer:

T6 is already in exponential form.

Step-by-step explanation:

The reason why T6 is already written in exponential form is beacuse nothing further can be done with this equation.

Answer:

1

Step-by-step explanation:

Using the general exponent rule, that

[tex]a^{0}[/tex] = 1, so

[tex]7^{0}[/tex] = 1

Answer:

-20√7

Step-by-step explanation:

Here. we want to write this in the simpler form

we can have 112 as; 16 * 7

√112 = √(16*7)

√112 = 4 √7

so, we have

-5 * 4 √(7 = -20 √7

Answer: The cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Step-by-step explanation:

Let x= Cost of one bag of chips

y= Cost of one bag of pretzels.

As per given, we have

5x+9y=16.95        ...(i)

x+y=2.55            ...(ii)

Multiply 5 to (ii), we get

5x+5y=12.75     ...(iii)

Eliminate (iii) from (i), we get

[tex]4y=4.2\\\\\Rightarrow\ y=1.05[/tex]

Put value of y in (ii), we get

[tex]x+1.05=2.55\\\\\Rightarrow\ x=2.55-1.05=1.5[/tex]

Hence, the cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Answer: D. 453 miles .

Step-by-step explanation:

Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.

At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour     [1 hour = 60 minutes],

Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]

[tex]=458-5=453\ miles[/tex]

Jessica is 453 miles from her home after 5 minutes she began returning home.

Hence, the correct option is D. 453 miles .

Answer:

she had $77 to her name

Step-by-step explanation:

Add the cost up from the cd & dvd then add the total from that and the 55

Answer:

She should've had 77 dollars before

Step-by-step explanation:

55 plus 12 = 67

67 plus 10 = 77

Answer: t=0.7+1.5

Step-by-step explanation:

The equation that represents the distance from A = (a, b) and B = (c, d) is

√(c - a)² + (d - b)² = 1.5

The distance between two points of a line is given as:

Distance = √(c - a)² + (d - b)²

We have,

Let points A and B have the coordinates.

A = (a, b)

B = (c, d)

Now,

Distance = √(c - a)² + (d - b)²

√(c - a)² + (d - b)² = 1.5

Thus,

The equation is

√(c - a)² + (d - b)² = 1.5

Answer: The numbers are 1 and 3.

Step-by-step explanation:

Let x = smaller number , y= larger number.

As per given,

[tex]x=\dfrac{y}{3}[/tex]   ...(i)

[tex]x+y=y^2-5[/tex]       ...(ii)

Put value of x from (i) in (ii)

[tex]\dfrac{y}{3}+y=y^2-5\\\\\Rightarrow\ \dfrac43y=y^2-5\\\\\Rightarrow\ 3y^2-4y-15=0\\\\\Rightarrow\ 3y^2-9y+5y-15=0\\\\\Rightarrow\ 3y(y-3)+5(y-3)=0\\\\\Rightarrow\ (y-3)(3y+5)=0\\\\\Rightarrow\ y=3 \ \ or\ y=\dfrac{-5}{3}[/tex]

Since numbers are positive , so y=3 is correct.

And x will be 1  [from (i)]

Hence, the numbers are 1 and 3.

Answer:

x = 35.1 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj/ hyp

cos x = 27/33

Take the inverse cos of each side

cos ^-1 ( cos x) = cos ^-1(27/33)

x =35.09680123

To the nearest tenth

x = 35.1 degrees

Answer:

x=35.1

Step-by-step explanation:

cos(x)=[tex]\frac{27^{2}+33^{2}-360 }{2(27)(33)}[/tex]

x=35.1(correct to the nearest tenth)
