Jack said that if you take a number and multiply it by a fraction, the product will always be smaller than what you started with

ELEN [110]

Answer:

Is not correct. The product not always will be smaller.

Step-by-step explanation:

A fraction could increase a number if you multiply it.

If the numerator is higher to the denominator, it will increase it.

If the numerator is smaller to the denominator, it will decrease it.

For example,

10 x 4/3

For fraction multiplication, multiply the numerators and then multiply the denominators to get

10×4/1×3=40/3= 13,33

13,33 is higher than 10.

5 x 10/3

For fraction multiplication, multiply the numerators and then multiply the denominators to get

5×10/1×3=50/3

16,66 is higher than 5.

Answer:

11 + x

Step-by-step explanation:

A = LW

W = $\frac{A}{L}$

Plug in given information:

W = $\frac{121-x^{2} }{11-x}$

Factor the numerator:

W = $\frac{(11+x)(11-x)}{(11-x)}$

Cancel (11 - x):

W = 11 + x

How does sin 30 compare to sin -30

Kisachek [45]

Answer:

c. sin 30 is positive and sin -30 is negative

Step-by-step explanation:

Picture the unit circle (which is attached). Sine is like the y-coordinate. And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a negative y-coordinate. 30 is above the x-axis, so it has a positive y-coordinate.
