trasher [3.6K]

Answer: There are 3 quarts of concentrate and 9 quarts of water.

Step-by-step explanation:

Since we have given that

Ratio of number of quarts of water to number of quarts of concentrate is

3:1

Number of quarts of orange juice from concentrate and water = 12 quarts

So, the number of quarts of concentrate would be

$\dfrac{1}{4}\times 12\\\\=\dfrac{12}{4}\\\\=3\ quarts$

the number of quarts of water would be

$\dfrac{3}{4}\times 12\\\\=3\times 3\\\\=9\ quarts$

Hence, there are 3 quarts of concentrate and 9 quarts of water.

Which is equivalent toStartRoot 10 EndRoot Superscript three-fourths x ?

DENIUS [597]

Answer:

I THINK its the last one (8 root 10 to the power of 3x)

Step-by-step explanation:

A square root is the same thing as raising something to the 1/2. So the expression we have is (10^1/2)^3/4x.

Due to exponent rules we can multiply to get

10^3/8x which is the same thing as 10^3x/8

The 8 goes to the root and the 3x becomes the exponent

2 A pharmacist has a 13 % alcohol solution and another 18 % alcohol solution. How much of each must he use to make 50 grams of a

nalin [4]

<h2>Therefore he took 40 gram of $1^{st}$ type solution and 10 gram of $2^{nd}$ type solution.</h2>

Step-by-step explanation:

Given that , A pharmacist 13% alcohol solution another 18% alcohol solution .

Let he took x gram solution of $1^{st}$ type solution

and he took (50-x) gram of $2^{nd}$ type solution.

Total amount of alcohol = $[x\times\frac{13}{100}] +[(50 -x) \times\frac{18}{100} ]$ gram

Total amount of solution = 50 gram

According to problem

⇔ $\frac{ [x\times\frac{13}{100}] +[(50 -x) \times\frac{18}{100} ]}{50}= \frac{14}{100}$

⇔ $\frac{13x +900-18x}{100\times50} =\frac{14}{100}$

⇔- 5x= 700 - 900

⇔5x = 200

⇔x = 40 gram

Therefore he took 40 gram of $1^{st}$ type solution and (50 -40)gram = 10 gram of $2^{nd}$ type solution.

The grades on a history midterm at Gardner Bullis are roughly symmetric with μ = 69 μ=69mu, equals, 69 and σ = 3.5 σ=3.5sigma, e

katrin2010 [14]

Answer:

-1.14

Step-by-step explanation:

The given information in statement is

mean=μ=69

standard deviation=σ=3.5

Let X be the Ishaan's exam score

X=65

The Z score can be computed as

$z=\frac{x-mean}{standard deviation}$

$z=\frac{65-69}{3.5}$

z=-1.1429

z=-1.14 (rounded to two decimal places).

Thus, the computed z-score for Ishaan's exam grade is -1.14.
