Dafna11 [192]

Answer:

s = 2j

Step-by-step explanation:

Given - Ada makes sparkling juice by mixing 2 cups of sparkling water

with every 4 cups of apple juice. Let s represent the number of

cups of sparkling water and j represent the number of cups of

apple juice.

To find - Write an equation that shows how s and j are related.

Proof -

Let total number of cups of sparkling water make = s

Total number of cups of apple juice make = j

Now,

Given that, Ada makes sparkling juice by mixing 2 cups of sparkling water with every 4 cups of apple juice.

⇒2s = 4j

⇒s = 2j

∴ we get

Ada can makes sparking water by mixing 2j cups of sparking water with every j cups of apple juice.

Answer:

The volume of cone = Maximum holding of glass = 60 cube cm(cm^3)

Step-by-step explanation:

Cone formula:

$v = \frac{1}{3} \pi \: r {}^{2} h$

The radius is 3cm and Volume is 60cm^3.

if pi =~ 3 So the "h" is 6.66 cm.

"h" is distance from cone's head to its base.

The "H"( height of glass) = 6.66 + 7 = 13.6 =~ 14

The production cost for a t-shirt printing company is a function of the number of t-shirts that are printed, t. The function tha

Answer:

Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.

Step-by-step explanation:

Given that,

The function that models the production cost is

$f(t)=0.1 t^2-6t+100$

To find the number of t-shirt, we put f(t)=40 in given function.

∴40= 0.1t²-6t+100

⇒ 0.1t²-6t+100-40=0

⇒0.1 t²- 6t +60=0

⇒t²-60t+600=0

Applying quadratic formula $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$ , a=1, b= - 60 and c=600

$t=\frac{-(-60)\pm\sqrt{(-60)^2-4.1.600}}{2.1}$

= 47.32,12.67

≈47, 12

Therefore the company have to print either 47 or 12 t-shirt for its production cost to be $40 or less.

The simplest form of the expression 4m-17/m^2-16 + 3m-11/m^2-16 has ____in the numerator and___ in the denominator.

lara31 [8.8K]

For this case we have the following expression:
$\frac{4m-17}{m^2-16} + \frac{3m-11}{m^2-16}$
Since the denominator is equal, then we can add the numerator.
We have then:
$\frac{(4m-17) + (3m-11)}{m^2-16}$
Adding similar terms we have:
$\frac{(4m+3m) + (-17-11)}{m^2-16}$
Rewriting we have:
$\frac{7m - 28}{m^2-16}$
Doing common factor in the numerator we have:
$\frac{7(m - 4)}{m^2-16}$
Factoring the denominator we have:
$\frac{7(m - 4)}{(m-4)(m+4)}$
Canceling similar terms we have:
$\frac{7}{m+4}$
Answer:
The simplest form of the expression has 7 in the numerator and m+4 in the denominator.
