Jim's stride measures $2\frac{1}{2}$ feet, and Jeffrey's stride measures $2\frac{2}{3}$ feet. There are 5280 feet in a mile. If
djyliett [7]

Answer:

\frac{16}{15}

Step-by-step explanation:

The number of stride Jim takes to walk a mile is  \frac{5280}{2\frac{1}{2}}=2112 strides

The number of strides Jeffrey takes to walk a mile is  \frac{5280}{2\frac{2}{3}}=1980 strides

Hence, ratio of number of strides of Jim to number of strides of Jeffrey is:

\frac{2112}{1980}=1\frac{1}{15}

Help please, need help
iren2701 [21]

Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base =  5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base =  30 :2  = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base =  60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

 m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x

Answer:

2677

Step-by-step explanation:

Let's make this easier first of all:

a^2-y^3(a-y^2)y^2

a^2-y^5(a-y^2)

a^2-ay^5+y^7

(-2)^2-(-2)(3)^5+3^7

4-(-2*243)+2187

4-(-486)+2187

4+486+2187
