CAN YOU HELP ME PLEASE

If I can walk 9673.6 meters in 5 hours. How far can I walk in 70 minutes. ( I need the work)

den301095 [7]

First, convert 5 hours into minutes:

5 hours 60 min

------------ * --------------- = 300 min

1 1 hr

Next, find the unit rate in m/min:

9673.6 m

--------------- = 32.24 m/min

300 min

Now find the distance you can walk in 70 minutes at this rate:

32.24 m

------------- * 70 min = 2247 meters (answer)

1 min

You could walk 2247 meters (to the nearest meter) in 70 minutes.

In graph, the area below f(x) is shaded and labeled A, the area below g(x) is shaded ad labeled B, and the area where f(x) and g

NNADVOKAT [17]

Answer:

The graph represents the system of inequalities y ≤ -3x + 2 and y ≤ -x + 2 ⇒ C

Step-by-step explanation:

From the given figure

∵ The direction of each line is to left

∴ The slopes of the lines are negative

∵ The slope of the line is the coefficient of x

∴ The coefficient of x in each inequality is negative ⇒ (1)

∵ The two lines intersect the y-axis at the point (0, 2)

∴ The y-intercept of the two lines is (0, 2)

∵ The y-intercept is the numerical term in the equation

∴ The numerical term in each inequality is 2 ⇒ (2)

∵ The two lines are solids

∵ The shaded area of each one is under the line

∴ The sign of inequality in both equations is ≤ ⇒ (3)

→ Look at the answer and find which one has the 3 conditions above

∵ y ≤ -3x + 2 and y ≤ -x + 2

∴ m = -3 and m = -1 ⇒ negative coefficients of x

∴ b = 2 ⇒ numerical term

∵ The sign of inequality is ≤

∴ The graph represents the system of inequalities y ≤ -3x + 2 and y ≤ -x + 2

Multiply (2x+3y) and (3x+4y-5z)<br>please answer this fast

ehidna [41]

Answer:

6x² + 12y² + 17xy - 25xz

Step-by-step explanation:

(2x + 3y) (3x + 4y - 5z)

= 6x² + 8xy - 10xz + 9xy + 12y² - 15yz

= 6x² + 12y² + 8xy + 9xy - 10xz- 15yz

= 6x² + 12y² + xy (8 + 9) - xz (10 + 15)

= 6x² + 12y² + 17xy - 25xz

PLEASE HELP!!!! Seventeen consecutive positive integers have a sum of 306. What is the sum of the seventeen consecutive integers

Dima020 [189]

Answer:

595

Step-by-step explanation:

Let the first integer be n. Then each consecutive integer will be (n+1), (n+2)... until (n+16).

First, from the formula $k/2(a+x_{k})$ , where k is the number of elements and xk is the last element, we can find 1+2+3 ... +15+16 = (16/2)(1+16)=136.

Anyways, this means that 17n+136=306.

We can find that n=10

Thus, the first integer is 10, and the 17th integer will be 10+16=26.

Thus, the first integer immediately proceeding 26 is 27. There are a total of 17 digits including 27 so we can add 16 to 27 to find the last digit, which is 43. There are again 17 digits in this set.

Thus, we have: 17/2(27+43)=595.

A 13.9 gallon gas tank is 4/5 full. How many gallons will it take to fill the tank?

Anna007 [38]

It will take 2.78 gallons to fill the remainder of the tank.

13.9 * 4/5 = 11.12 - 11.12 is the amount of gas already in the tank.

13.9 - 11.12 = 2.78 - So, subtract 11.12 from 13.9 and you get your answer.

Hope this is right! ;)
