Answer:
2500 kg
Step-by-step explanation:
Given:
• Force produced by the truck = F = 15,000 Newtons Acceleration of the truck = a = 6 m/s²
To find:
Mass of the truck if force is 15000 newtons and acceleration is 6 m/s²
Formula:
Force = Mass Acceleration
Substituting the above values:
15000N Mass×6
Mass = 15,000/6
Mass = 2500 kg
Answer:
A. −19z − 77
Step-by-step explanation:
−9(z + 3) − 5(2z + 10)
The first step is to distribute
-9*z -9*3 -5*2z -5*10
-9z-27 -10z-50
-19z -77
Let x be the digit in the tens place and y be the digit in the ones place.
so, the digit is xy
<span>
The ten's digit of a two digit number is 1 more than 4 times the units' digit.
</span>x = 4y + 1
<span>63 is subtracted from the number, the order of the digits is reversed
</span>10x + y - 63 = 10y + x
9x - 9y = 63
x = 4y + 1 ------------ (1)
9x - 9y = 63 ---------- (2)
Sub (1) into (2)
9(4y + 1) - 9y = 63
36y + 9 - 9y = 63
27y = 63 - 9
27y = 54
y = 2 ------- sub into (1)
x = 4(2) + 1 = 9
x = 9, y = 2
The number is 92
