Answer: 13 miles per hour

Step-by-step explanation: 52 divided by 4 to find unit rate

The speed of bike which covers 52 miles in 4 hours is 13 miles per hour.

In unit time the distance covered by any object is called speed.

In mathematical term, Speed is express as S=D/T,

where S=speed, D=distance, T= time.

Given that,

The distance covered by bike in 4 hours = 52 miles.

To find the speed of the bike,

Use formula

Speed = distance / time

Since, distance is 52 miles and time is 4 hours,

Therefore, speed = 52 / 4 = 13 miles per hour

The required speed of bike is 13 miles per hour.

Answer:

C.(-31)

Step-by-step explanation:

= 5 - 4(1 + 2^3)

= 5 - 4(1 + (2 . 2 . 2))

= 5 - 4(1 + (4 . 2))

= 5 - 4(1 + 8)

= 5 - 4(9)

= 5 - (4 . 9)

= 5 - 36

= (-31)

= -31

Answer:

15 degrees

Step-by-step explanation:

3x+3x+90=180 (all angles in a triangle add to 180 degrees)

3x+3x=6x so 6x+90=180 degrees

To isolate 6x we -90 from 180 therefore 6x=90 degrees

To get x on its own, we then must divide 90 by 6 which is 15 hence why...

x=15 degrees

Answer:

x = 85

Step-by-step explanation:

To solve, first find the angle of the other missing angle in the left by subtracting the outside angle from 180:

180 - 155 = 35

Then add this and the known angle:

35 + 60 = 95

Then subtract this from 180 to get the missing angle for x:

180 - 95 = 85

The expressions [tex]1.8^2 + 3 $ and $ 7 - 2 \times 0.43[/tex] ​ should be joined by not equals sign to form an inequality.

Given the expressions, 1.8² + 3 and 7 − 2⋅0.43,

Evaluate each of the expressions to find out if they are equal or not.

Thus:

1.8² + 3 = 3.24 + 3

1.8² + 3 = 6.24

7 − 2⋅0.43 = 7 - 0.86

7 − 2⋅0.43 = 6.14

x=45

5(y-10)

Angles facing each other symmetrically are equal. so 4x-40 is equal to 3x+5. so x is 45 degrees.

m = (Y2 - Y1)/(X2 - X1)

m = (1 - (-3))/(1 - (-2))

m = (1 + 3)/(1 + 2)

Answer:

  D. 43 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180°. If x represents the measure of the third angle, then ...

  75° +62° +x = 180°

  137° +x = 180° . . . . . . . . . collect terms

  x = 180° -137° = 43° . . . . subtract 137° from both sides of the equation

The third angle measures 43°.
