Hey there! I'm happy to help!

Standard form is just writing this without the multiplication sign. If you multiply a number by 10 to a negative number, \you take the number in the negative exponent and move the decimal to the left that many times. In our case, we move it to the left 8 times.

If we move the decimal to the left 8 times, we have 0.00000007.

I hope that this helps! :D

Options of Answer

Naya [18.7K]

Answer:

D) 18 bags of chips and 6 jars of salsa

Step-by-step explanation:

Given : The networking organization you joined is throwing a party. You are in charge of buying the chips, which cost $2.50 per bag and salsa, which costs $4 per jar. The chips & salsa budget you are given totals $60.

Inequality: $2.5x+4y$ ≤ $60$

Solution :

x represents chips

y represents salsa

Option a: 10 bags of chips and 2 jars of salsa

so, x = 10 and y =2

Putting values in inequality

$2.5(10)+4(2)$ ≤ $60$

$25+8$ ≤ $60$

$33$ ≤ $60$

Hence it is correct.

Option c : 14 bags of chips and 5 jars of salsa

so, x = 14 and y =5

Putting values in inequality

$2.5(10)+4(2)$ ≤ $60$

$50+8$ ≤ $60$

$58$ ≤ $60$

Hence it is correct.

Option c : 14 bags of chips and 5 jars of salsa

so, x = 14 and y =5

Putting values in inequality

$2.5(14)+4(5)$ ≤ $60$

$35+20$ ≤ $60$

$55$ ≤ $60$

Hence it is correct.

Option d :18 bags of chips and 6 jars of salsa

so, x = 18 and y =6

Putting values in inequality

$2.5(18)+4(6)$ ≤ $60$

$45+24$ ≤ $60$

$69\geq 60$

Hence it is not correct since it violates the inequality

What is -9x+6=18 in slope intercept form ?

S_A_V [24]

Answer:

y = 3/2 x + 3

Step-by-step explanation:

-9x + 6y = 18 is in standard form (ax + by = c).

Slope-intercept form isolates the "y" variable. It looks like this:

y = mx + b

Move anything that's not "y" to the right side. Move things in reverse BEDMAS order, using reverse operations of what you want to move.

$-9x + 6y = 18$ Move -9x by doing +9x to both sides

$-9x + 9x + 6y = 18 + 9x$ Simplify. -9x + 9x will cancel out.

$6y = 18 + 9x$ Move the "6" that multiplies with "y".

$\frac{6y}{6} = \frac{18}{6} + \frac{9x}{6}$ Divide each term by 6.

$y = 3 + \frac{3x}{2}$ "y" is isolated. Simplify the rest.

$y = \frac{3}{2}x + 3$ Rearrange to match slope-intercept form.

fiona draws a 24 centimeter rectangle.gregory draws a 24 square inch rectangle.whose rectangle is in area .how do you know

Valentin [98]

Answer:

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.

Step-by-step explanation:

Given:

Fiona draws a 24 centimeter rectangle.

Gregory draws a 24 square inch rectangle.

To Find:

Whose rectangle is in area = ?

Solution:

Rectangle has a dimension as

Length and Width which are in meters, centimeters, inches, feet, units, etc.

For Area

$Area\ of\ Rectangle=Length\times Width$

here units are getting Multiplied so it becomes

unit × unit = unit² = square units

m × m = m² =square meter

inch × inch = inch² =square inches

Hence Area is calculated in square units.

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.

Answer:

(D) $\frac{\sqrt{x}}{x}$

Step-by-step explanation:

$\frac{3x^2}{\sqrt{9x^5}}=\frac{3x^2}{3\sqrt{x^5}}=\frac{\sqrt{x^4}}{\sqrt{x^5}}=\sqrt{\frac{x^4}{x^5}}=\\=\sqrt{\frac{1}{x}}=\frac{1}{\sqrt{x}}=\frac{\sqrt{x}}{x}$
