The answer is 45 muffins

Answer:

You started out with 45 muffins

Step-by-step explanation:

If 4/9 is 20, all we have to do if subtract 5 from 20 which would be 3/9. Since 3 is 1/3 of 9, all we have to do now is multiply 15 by 3.

15 × 3 = 45

Which is traveling faster, a car whose velocity vector is 201 + 25), or a car whose velocity vector is 30i, assuming that the un

ioda

Answer with explanation:

For any object having the velocity vector as

$\overrightarrow{v}=v_x\widehat{i}+v_y\widehat{j}+v_z\widehat{k}$

the magnitude of velocity is given by

$|v|=\sqrt{v_x^2+v_y^2+v_z^2}$

For car 1 the velocity vector is

$\overrightarrow{v}_1=20\widehat{i}+25\widehat{j}$

Therefore

$|v_1|=\sqrt{20^2+25^2}\\\\\therefore v_1=32.0156units$

Similarly for car 2 we have

$\overrightarrow{v}_2=30\widehat{i}$

Therefore

$|v_2|=\sqrt{30^2}\\\\\therefore v_2=30.0units$

Comparing both the values we find that car 1 has the greater speed.

Rewrite the equation 2x+6x^(2)-1=3x^(2) in standard form and identify a, b, and c.

Fed [463]

Hi there!

$2x + 6 {x}^{2} - 1 = 3 {x}^{2}$
First subtract 3x^2 from both sides.

$2x + 3 {x}^{2} - 1 = 0$
Now rearrange the equation.

$3 {x}^{2} + 2x - 1 = 0$
Finally we can see our answer.

$a = 3$
$b = 2$
$c = - 1$

The larger of to numbers is 12 more than the smaller. Their sum is 84. What are the two numbers?

Nataly_w [17]

36 and 48

a = b+12
a+b = 84

(b+12) + b =84
2b +12 = 84
2b = 72
b= 36

a = b + 12
a = 36 + 12
a = 48
