The value of x that makes lines a and b parallel is 76°.

This is because when two parallel lines are cut by a transversal, the alternate angles formed by the transversal are equal. In the figure below, the angle x is an alternative interior angle to the angle measured 76°, so they are equal. That is, x = 76° (provided that line a is parallel to line b)

John swims 5/12 of a mile in 3/8 of an hour what distance in miles does John swim in an hour

Setler79 [48]

Answer:

1.1 mph

Step-by-step explanation:

Step one:

John swims a distance of 5/12 miles

time taken = 3/8 of an hour

Required

The speed with which John swims

Step two:

speed= distance/time

substituting we have

speed= 5/12/3/8

multiply the numerator by the inverse of the denominator

speed= 5/12*8/3

speed= 40/36

speed= 1.1 mph

vagabundo [1.1K]

Answer:

1.8 ; 11.8 ; 4.18

Step-by-step explanation:

Given the data:

X : 2.4,1.6, 3.2,0.3, 1.5

Mean, m = Σx / n

Σx = 9 ; n = 5

m = 9 /5

m = 1.8

If data is increased by 10:

X : 12.4, 11.6, 13.2, 10.3, 11.5

Σx = 59 ; n = 5

m = 59 /5

m = 11.8

If data values is doubled :

X : 5.76, 2.56, 10.24, 0.09, 2.25

Σx = 20.9 ; n = 5

m = 20.9 /5

m = 4.18

Answer:

(h*h)(10) is the same as h(10)*h(10). Let's find the value of h(10) first. To do this, replace every x with 10 like so

Step-by-step explanation:

h(x) = 6-x

h(10) = 6-10

h(10) = -4

So,

h(10)*h(10) = (-4)*(-4)

h(10)*h(10) = 16

The final answer is 16
