Answer:

The correct option is 2.

Step-by-step explanation:

The formula of force is

$F=ma$

Where, F is force, m is mass of the object and a is acceleration.

A pumpkin with a mass of 2.5 kg was pushed toward a wall. The average acceleration of the pumpkin was 10.7 m/s².

Put m=2.5 and a=10.7 in the above formula.

$F=2.5\times 10.7$

$F=26.75$

Unit of force is N.

Therefore the force was applied to the pumpkin to make it move is 26.75 N. The correct option is 2.

3(12x – 9) + 9 = 2x + 4 Would this be infinite solution, one solution or no solution?

timama [110]

Answer:

One solution

Step-by-step explanation:

Let us first expand the left side of the equation to rid of the parenthesis:

$3*12x-3*9+9=2x+4\\36x-27+9=2x+4\\36x-18=2x+4$

Now let us isolate the variable to sove for x:

$36x-2x=4+18\\34x=22\\x=\frac{22}{34}\\x=\frac{11}{17}$

Therefore, x= $\frac{11}{17}$ . As you can see, there is just one solution.

I hope this helps! Please let me know if you have any further questions :)

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w

netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

$\frac{1}{2} \times 100 = 50$

Add both skateboarding and walking

$30\% + 50\%\\\\= 30 + 50\\\\= 80$

Now, subtract that from a whole percent

$100 - 80 = 20\\\\20\%$

Convert it to a decimal

$20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2$

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

Can anyone solve this:

ludmilkaskok [199]

So fuctions mean
if
f(x)=x+2 then if you put in 3 for x then
f(3)=3+2=5 so

if x=years after 2000
in 2020 then
2020-2000=20 so x=20
subsitute
f(20)=9204e^0.022(20)

e could be:
1. common base of logarithms (memorised to 15 decmals) 2.718281828459045
2. a computer notation exg if you have 3e11 that means 3 times 10^11

if it is 1
9240 times (2.718281828459045^(0.022 times 20))=( simplify exponent first) 9240 times (2.718281828459045^0.44)=9204 times 1.5527072185113=14291.1 or rounded to 14291

if it is 2
9204 times 10^(0.022 times 20)=9204 times 10^(0.44)=9204 times 254.491 rounded to 254

so the answer dependes on what e represents,

if e is:
1. common base of logarithms (memorised to 15 decmals) 2.718281828459045, then answer is 14291

2. a computer notation exg if you have 3e11 that means 3 times 10^11 =254
