Answer:

$3.05 i'm pretty sure

Step-by-step explanation:

If one pound is $0.94 and she bought 3.25 pounds you multiply 3 by 0.94 and get $2.82 (we multiply by 3 to make it easier and to deal with the .25 later) then now we deal with the .25, since .25 is 1/4 in fraction just find out what 1/4 of .94 is which is .23 cents. So add $2.82 and $0.23 and you get $3.05

Answer:

A. x-4y=8

Step-by-step explanation:

Slope = [tex]\frac{1}{4}[/tex]

y-intercept = -2

In y=mx+b

m = slope

b = y-intercept

Just replace m with 1/4 and b  with -2

[tex]y = \frac{1}{4} x -2\\[/tex]

Multiply through by 4 and re-arrange

[tex]4(y=\frac{1}{4} x -2)\\\\4y =x -8\\0 =-4y +x-8\\8 =-4y+x\\\\x -4y =8[/tex]

Step-by-step explanation:

Microbes are generally described as being microscopic in size. ... In comparison to animal cells, microbes tend to be smaller. They are about 1/10th the size of a typical human cell. Microbes are generally measured in the scale of one millionth of a meter, which is known as a micrometer. i hope this is helpful.

Answer:

Option C. is the correct answer

Step-by-step explanation:

Choose any value of x and find the values of y. Then plot a graph using all that points. These will neither parallel nor perpendicular.

Answer:

I'm not sure what you mean by opposite, but by all means the opposite of 0.93 would be -0.93 as it's the negative value of that decimal.

Step-by-step explanation:

Answer:

I believe the standard form is: ax2+bc+c=0

Vertex form is:f(x)=a(x-h)2+k

Factored form is: y=1/2(x-6)(x+2)

Step-by-step explanation:

The ax2= ax squared and the (x-h)2= (x-h) squared

Answer:

[tex]\huge\boxed{A=(9x^2-48x+64)ft^2}[/tex]

Step-by-step explanation:

The formula of an area of a square:

[tex]A=s^2[/tex]

[tex]s[/tex] - side of a square

We have [tex]s=(3x-8)ft[/tex]

Substitute:

[tex]A=(3x-8)^2[/tex]

METHOD 1:

Use  [tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]A=(3x)^2-2(3x)(8)+8^2=9x^2-48x+64[/tex]

METHOD 2:

Use FOIL: [tex](a+b)(c+d)=ac+ad+bc+bd[/tex]

[tex]A=(3x-8)(3x-8)=(3x)(3x)+(3x)(-8)+(-8)(3x)+(-8)(-8)\\\\=9x^2-24x-24x+64=9x^2-48x+64[/tex]

Answer:

9x^2-48x+64 ft^2

Step-by-step explanation:

(3x − 8) (3x − 8)

Multiply 3x by (3x − 8)

3x(3x − 8)

9x^2-24x

Multiply - 8 by (3x − 8)

- 8(3x − 8)=-24x+64

Combine 9x^2-24x and -24x+64

9x^2-48x+64 ft^2

Answer:

the surface  area of a penny = 662.81 mm²

Step-by-step explanation:

given:

A penny is a cylinder with a diameter of 19.05 millimeters

and a thickness of 1.55 millimeters.

find:

what is the surface  area of a penny?

surface area of a cylinder formula:

As = 2 π r h + 2 π r²

let r = 19.05 / 2

r = 9.53 mm

let h = 1.55mm

plugin values into the formula:

As = 2 π (9.53) 1.55    +    2 π (9.53)²

As = 92.76 +  570.05

As = 662.81 mm²

therefore,

the surface  area of a penny = 662.81 mm²

Answer:

the surface  area of a penny = 662.81 mm²

Answer:

C

Step-by-step explanation:

Because of the -5 and the exponent it can be either positive or negative.

Answer:

d.imaginary and unequal

Step-by-step explanation:

In an effort to address this problem, mathematicians "created" a new number, i, which was referred to as an "imaginary number", since it was not in the set of "Real Numbers". This new number was viewed with much skepticism. The imaginary number first appeared in print in the year 1545

The imaginary number "i" is the square root of negative one.

neg i

An imaginary number possesses the unique property that when squared, the result is negative.

Answer:

Step-by-step explanation:

To find the equation of the line given the slope and a point we use the formula

[tex]y - y_{1} = m(x - x_{1})[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the slope is 8 and the point is ( - 9 , - 7)

Substitute the values into the above formula and solve for the equation

We have

[tex]y + 7 = 8(x + 9) \\ y + 7 = 9x + 72 \\ y = 9x + 72 - 7[/tex]

We have the final answer as

Hope this helps you

Answer:

Yes, 9.52 is less than 90.13

Step-by-step explanation:

Because 90 is a whole number from the decimal 90.13, and 9 is the whole number from the decimal 9.52

Compare 90 and 9. 90 is greater; therefore, 9.52 is less than 90.13

Answer:

All statements are true, but if you try to reverse them they won't necessarily be true.

Let's try:

Square ⇒ Has 4 sides

But if something has 4 sides it doesn't mean it's a square (example: rectangle)

Angle is 80° ⇒ acute angle

But acute angle is any angle below 90°, not just 80° so the reverse isn't true.

x – 17 = 4 ⇒ x = 21

And if we reverse

x = 21 ⇒ x – 17 = 4

we see that it's true for either direction.

x = 7 ⇒ |x| = 7

But |x| = 7 doesn't mean that x has to be 7, x can also be -7, so the reverse isn't true.

x – 17 = 4, then x = 21

Step-by-step explanation:

We can use the pythagorean theorem to solve this

The pythagorean theorem = a^2 + b^2 = c^2, while

a = one leg

b = the second leg

c = the hypotenuse

In this problem,

a = 3

b = 15

c = ?

Let's plug our values into the pythagorean theorem

(3)^2 + (15)^2 = c^2

9 + 225 = c^2

Add together the left side

234 = c^2

Take the sqrt of both sides

sqrt(234) = c

The length of BC = sqrt(234)
