Average speed = Total distance / Total time
Here, distance = 1 1/3 miles = 4/3 miles
Time = 1/4 hours
So, it would be: 4*4/1*3 = 5.33 miles/hour
Answer:
3. x=14° y=7
4. x=29° y=3
Step-by-step explanation:
3. this is a 45 - 45- 90 triangle
so the side is a-a-a√2 ( two sides are the same)
4y-3=10+2y+1 -- collect like terms
4y-2y=10+1+3
2y=14
y=7
find the angle of the inside triangle
180-59-90 =
31°
we know the big triangle was a 45-45-90 angle
so x+31=45
x=45-31
x=14°
4. this is a square, all sides are same
5y+3y=24
8y=24
y=3
angle is 90°
x+x+9y+5=90
we know y=3 --substitute
x+x+9(3)+5=90
2x+27+5=90
2x=90-27-5
2x=58
x=58/2
x=29
Answer: The value of x is 60 and two prime numbers are 2 and 3
Step-by-step explanation:
This is because 2 multiplied by 30 is 60 and 2 and 3 are prime numbers because their only factors are one and themselves.
Answer:
m=0
Step-by-step explanation:
m=y2-y1/x2-x1
m=1/2-1/2/-2-7
m=0/-9
m=0
