When making a batch of orange juice for her basketball team Jackie used 5 times as much water as concentrate. There were 32 more

AnnZ [28]

Answer:

48 cups of orange juice, 24 containers.

Step-by-step explanation:

Given:

Jackie used 5 times as much water as concentrate to make orange juice.

There were 32 more cups of water than concentrate.

Question asked:

How much juice did she make in all ?

She poured the juice in 2 quart containers how many containers could she fill ?

Solution:

Let concentrate used in the juice = $x$

<u>As Jackie used 5 times as much water as concentrate:</u>

Then water used in the juice = $5x$

<u>According to question:</u>

<u>To make orange juice 32 more cups of water used than concentrate is equals to to make orange juice</u>, Jackie used 5 times as much water as concentrate, we will write this as:-

$x+5x=x+x+32\\6x=2x+32\\$

Subtracting both sides by $2x$

$4x=32\\$

Dividing both sides by 4

$x=8$

Concentrate used in the juice = $x$ = 8 cups

Water used in the juice = $5x$ = $5\times8=40\ cups$

Total quantity of juice =8 + 40 = 48 cups

Thus, she made 48 cups of orange juice for her basketball team.

Now, as she poured the juice in 2 quart containers, we have to find number of containers could be filled, we will simply divide total quantity of juice by 2 quart

Number of 2 quart containers = 48 cups $\div$ 2 = 24 containers

Thus, she can fill 24 containers.

Why is the petrol price cheaper at coastal than inland

Daniel [21]

Answer: If a litre of fuel at the coast (95 octane) costs R13,89, then 38% is tax. The difference between inland and coastal fuel prices is mainly due to transport costs of the fuel from depots at the coat to inland outlets.

Describe how (2 cubed) (2 superscript negative 4) can be simplified.

Varvara68 [4.7K]

<u>Given</u>:

The given expression is $(2^3)(2^{-4})$

We need to determine how the expression can be simplified.

<u>Simplifying the expression:</u>

Let us determine how the expression can be simplified.

The expression is given by

$(2^3)(2^{-4})$

Applying the exponent rule that $a^{b} \cdot a^{c}=a^{b+c}$ in the above expression, we get;

$2^{3} \cdot 2^{-4}=2^{3-4}$

Adding the exponents, we get;

$2^{3} \cdot 2^{-4}=2^{-1}$

Again, applying the exponent rule $a^{-1}=\frac{1}{a}$ , we get;

$2^{3} \cdot 2^{-4}=\frac{1}{2}$

Thus, the simplified expression is $\frac{1}{2}$

Hence, the expression is simplified by adding the exponents and keep the same base. Then find the reciprocal and change the sign of the exponent.

Therefore, Option D is the correct answer.

Z varies directly as x2. If z = 16 when x = 2, find z when x = 5.<br> ...<br> Z=

PtichkaEL [24]

Answer:

100

Step-by-step explanation:

it is a bit unclear to me, what that problem description means.

if I understand it correctly, than z is directly depending on x².

so, z = 16 for x = 2. x² = 4

I pondered a little bit, as there are several possibilities to connect 16 with 4 as a driving factor (e.g. 2⁴ = 16, 4×4 = 16, 12 + 4 = 16).

I decided to go with the simplest interpretation with the usual meaning of "varies" (multiplication) : 4×x²

that would mean

z = 4×x² = 4×5² = 4×25 = 100
