Rate is given by:
rate=(distance )/(time)
Martin's rate will be:
(3 1/3)/(1/6)
=(10/3)/(1/6)
=20 meters per hour

Alexia's rate is:
(17 1/2)/(5/6)
=(35/2)/(5/6)
=21 meters per hour

The mean age of 9 women in an office is 27 years old.
Veronika [31]

26 to nearest year

We require the total of the sums of ages for both groups before calculating the mean for all 16

using mean = \frac{sum}{count}

Women

27 = \frac{sum }{9} ( cross- multiply )

sum = 9 × 27 = 243

Men

25 = \frac{sum}{7} ( cross- multiply )

sum = 7 × 25 = 175

Total sum of all 16 = 243 + 175 = 418

mean = \frac{418}{16} = 26 ( to nearest year )

what is the smallest of 3 consecutive positive integers if the product of smaller two interfere is 5 less than 5 times the large
Lady_Fox [76]

Answer:

Two options:

5,6, and 7

-1,0,and 1

Step-by-step explanation:

Three consecutive natural numbers can be represented as n, n+1, and n+2.

The product of the smaller two would be n(n+1). The less than 5 times the larger is 5(n+2)-5.

Set them equal and solve by factoring:

n(n+1) = 5(n+2) -5\\n^2+n = 5n+10 -5\\n^2+n = 5n+5\\n^2 -4n-5=0\\(n-5)(n+1)=0

Set each factor equal to 0.

n-5==0 so n=5.

n+1=0 so n=-1.

This means the 3 consecutive numbers would be 5,6, and 7

OR

-1, 0 or 1.

Please help, easy geometry​
iVinArrow [24]

Answer:

  26 cm²

Step-by-step explanation:

The area of the rectangle whose dimensions are shown at the right and bottom is ...

  (6 cm)(7 cm) = 42 cm²

The figure is smaller than that by the area of the space whose dimensions are shown at the right and in the middle left:

  (4 cm)(4 cm) = 16 cm²

The figure area is then the difference ...

  42 cm² - 16 cm² = 26 cm²

_____

<em>Alternate solution</em>

Draw a diagonal line between the lower right inside corner and the lower right outside corner. This divides the figure into two trapezoids.

The trapezoid at lower left has bases 7 and 4 cm, and height 6-4 = 2 cm. Its area is ...

  A = (1/2)(b1 +b2)h = (1/2)(7 + 4)(2) = 11 . . . . cm²

The trapezoid at upper right has bases 6 cm and 4 cm and height 3 cm. Its area is ...

  A = (1/2)(b1 +b2)h = (1/2)(6 + 4)(3) = 15 . . . . cm²

Then the area of the figure is the sum of the areas of these trapezoids, so is ...

  11 cm² + 15 cm² = 26 cm²

_____

<em>Comment on other alternate solutions</em>

There are many other ways you can find the area of this figure. It can be divided into rectangles, triangles, or other figures of your choice. The appropriate area formulas should be used, and the resulting partial areas added or subtracted as required.

You can also let a geometry program find the area for you. (It is 26 cm².)
