Answer: 23.92 kJ

Step-by-step explanation:

Given

Distance moved by wagon is d=1.2\ km

Force F=22\ N directed at an angle of 25^{\circ} above the horizontal

Only the horizontal component of the force that is, 22\cos 25^{\circ}the wagon will cause the wagon to move, while the other force is perpendicular to the wagon and thus produce zero displacements.

Work done is

W=F\cdot s\\W=22\times 1.2\times 10^3\times \cos 25\\W=23.92\ kJ

thus, 23.92 kJ of work is done on the wagon.

According to the general equation for conditional probability, if P(A upside down u B)= 5/7 and P(B)=7/8 , what is P(A|B)?
natta225 [31]
P(A | B) = \frac{P(A \cap B)}{P(B)}


P(A|B) = \frac{5/7}{7/8}


P(A|B) = \frac{5}{7} \div \frac{7}{8}


P(A|B) = \frac{5}{7}\times\frac{8}{7}


P(A|B) = \frac{5*8}{7*7}


P(A|B) = \frac{40}{49}

Mr and mrs. Dorsey and their three children are fling to Springfield. The cost of each ticket is $179. Estimate how much the tic
Soloha48 [4]
<span>First figure out how many people there are all together. So mrs and mr is 2 there three children so 2+3=5 so next round 179 to 200 and multiply 200x5. To do that you can use the mental math way witch would be to take the whole number out of 200 and make it 2. Then take the 5 in 200x5 and multiply 2x5. Then add the 2 zeros there were. And your estamated answer would be 1,000.
2+3=5
179=200
200x5
2x5=10
1,000
To figure out your real answer you will have to take 179 and multiply it by 5 so it will look like this:
 34
179
x
   5
895
Soto conculde the answer would be:

Estamated: $1,000

Exact: $895

Hope this helps!</span>
