Answer:

Rick has 12 cups of glue

Step-by-step explanation:

so we know that 1 cup is 1/18 so we need to convert 2/3 into eighteenths. I know that 3 × 6 is 18 so 2/3 × 6 is 12/18 so rick has 12 cups of glue

Hey guys please help!!

Advocard [28]

Answer:

Yes

Step-by-step explanation:

g(x) = - $\frac{1}{4}$ x + $\frac{1}{4}$

y = - $\frac{1}{4}$ x + $\frac{1}{4}$ ....... (1)

(1) × 4

4y = - x + 1

x = - 4y + 1

y = - 4x + 1

f(x) = - 4x + 1

∴ f(x) and g(x) are inverses

Which would be the best method to use to solve the following equations? Explain your reasoning.

o-na [289]

A. square root property

$3x^2-192=0\\x^2-66=0\\x^2=66\\x= -\sqrt{66} or \sqrt{66}$

it has one value with x which is x^2 and it cn be easily solved without having to factorise, quadratic formula cant be used as it need ax^2+bx+c=0 format

B. factorising

$x^2-x-6=0\\x^2+2x-3x-6=0\\(x+2)(x-3)=0\\x+2=0 and x-3=0\\x= -2 \\x= 3$

i just felt like this was easier to factorise than the other 2 options left

C. Completing the square

$x^2-6x-7=0\\(x-3)^2=0\\x= -1\\x= 7$

same reason personal preference

D- Quadratic

$x^2-17x-7=0\\x=\frac{-(-17)+\sqrt{(-17)^2-4(1)(-7)} }{2(1)} \\x=\frac{-(-17)-\sqrt{(-17)^2-4(1)(-7)} }{2(1)}\\x=17.4\\x=-0.402$

the 17 kinda threw me off and i didnt wanna get on factorising or doing completing the square so quadratic formal

Rufus collected 100 pounds of aluminum cans to recycle. He plans to collect an additional 25 pounds each week. Right and crafty

Viktor [21]

It will take 16 weeks to collect 400 cans
So 16 multipled by 25 would give you 400

Answer: medium 18. Range 6 ,25th percentile 17 , 75th percentile 20 ,IQR 3

Step-by-step explanation from the given figure, median is equal to 18, the range is equal to 21-15 equal to 6. The 25th percentile is equal to17 while the 75th is equal to 20. IQR then is equal to 20-17 equal to 3.
