Answer:

12 is your answer

Step-by-step explanation:

1.Flip the sides of the equation so 24/34 is on the right side

2. You then cancel the common factor so your 24/34 turns into 12/17

3. Multiply each side by 85. '

Then simply your new equation will look like this;

4y+12=60

4. subtract 12 from both sides

5. Get 48

5. Divide both sides by 4

6. Your answer is 12

If 35.4067=3/p+5/q+4r+6/s+7t, then the value of 2p+4q+5r+7s+3t

sweet [91]

Answer:

7004.7003

Step-by-step explanation:

We are given the following information in the question:

$35.4067=\displaystyle\frac{3}{p}+\frac{5}{q}+4r+\frac{6}{s}+7t$

We know that,

$35.4067 = (3\times 10^1) + (5\times 10^0) + (4\times 10^{-1})+(0\times 10^{-2}) + (6\times 10^{-3}) + (7\times 10^{-4})$

Comparing the two equations, we get:

$\displaystyle\frac{1}{p} = 10^1\\\\p = 10^{-1}\\q = 10^0\\r = 10^{-1}\\s = 10^3\\t = 10^{-4}$

We have to evaluate:

$2p+4q+5r+7s+3t$

Putting values, we get:

$(2\times 10^{-1}) + (4\times 10^0) + (5\times 10^{-1}) + (7\times 10^3) + (3\times 10^{-4})\\=0.2 + 4 + 0.5 + 7000 + 0.0003\\=7004.7003$

Over the entire six years that students attend an ohio elementary school, they are absent, on average, 28 days due to influenza.

qaws [65]

The probability that the sample mean is less than 30 school days will be given as follows:
the z-score is given by:
z=(x-μ)/σ
where
μ- stand deviation
σ-mean
thus the z-score of our information is:
z=(30-28)/9
z=0.222222
hence the probability that the sample mean is less than 30 will be:
P(x<30)=0.5871~58.71%

On a map, 1 inch equals 20 miles. Two cities are 7 inches apart on the map. What is the actual distance between the cities?

MrRa [10]

Answer:

140 miles

Step-by-step explanation:

1 times 20 (1 inch=20 miles)

2 times 20 (2 inches=40 miles)

3 times 20 (3 inches=60 miles)

4 times 20 (4 inches=80 miles)

5 times 20 (5 inches=100 miles)

6 times 20 (6 inches=120 miles)

7 times 20 (7 inches=140 miles)

Hope this helped!! :)
