Answer:

266\frac{2}{3}

Step-by-step explanation:

if a 45 minute workout is 1000 calories, at the same rate, a 12 minute workout would be 266 calories and 2 thirds. \frac{12}{45} x 1000 = 266\frac{2}{3}

The partial pressure of carbon dioxide in a mixture is 0.31 atm.
juin [17]

Answer:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and X_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm

Step-by-step explanation:

For this case the partial presure of carbon dioxide is given by:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and x_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm

For the given expression, which whole number (w) will make the expression true? 5/6
Sonja [21]

Answer:

D. 7

Step-by-step explanation:

The question is incomplete. Here is a possible complete question

For the given expression, which whole number (w) will make the expression true? 5/6 < w/6

A. 3

B. 4

C. 5

D. 7

Given the inequality expression:

5/6 < w/6

Cross multiply

5×6 < 6×w

30<6w

Divide both sides by 6

30/6 = 6w/6

5<w

Reciprocate both sides(this will change the sense of the inequality)

1/5>1/w

Cross multiply

w > 5×1

w>5

This shows that the value of w is a value greater than 5 but not 5. According to the option, the only value greater than 5 is 7. Hence the whole number (w) that will make the expression true is 7

Help middle school question!!!
Sav [38]

Answer:

<em>The shaded region has an area of 1400 square units</em>

Step-by-step explanation:

<u>Area of Compound Shapes</u>

We are given a shape and it's required to calculate its area. The shape can be divided into three rectangles as shown in the figure attached below.

The lengths of these rectangles are x, y, and z.

The value of x can be calculated as:

x = 60 - 15 - 10 = 35

Similarly:

y = 60 - 15 = 45

z = y = 45

The first rectangle has dimensions of x by 10, thus its area is:

A1 = 35*10 = 350

The second rectangle has dimensions of 60 by 10:

A2 = 60*10 = 600

The third rectangle has dimensions y by 10:

A3 = 55*10 = 450

The shaded area is:

A = 350 + 600 + 450 = 1400

The shaded region has an area of 1400 square units
