Answer:

176 words

Step-by-step explanation:

1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:

<u>44 words</u> = <u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>x</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

1 minutes = 4 minutes

2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.

3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!

4) multiplying 44 by 4 would get us our answer which is 176

im not the best at math but i this explanation helped <33

Step-by-step explanation:

\sqrt{36/4} =\sqrt{36} /\sqrt{4}

\sqrt{36}=6

\sqrt{4} =2

6/2=3

He equation sin (40 degree) equals StartFraction b Over 20 EndFraction can be used to determine the length of line segment AC.
Alisiya [41]

Answer:

The value of b is 12.9 cm

The value of a is 15.3 cm

Step-by-step explanation:

see the attached figure to better understand the problem

<em>Find the value of b</em>

we know that

in the right triangle ABC

The function sine of angle of 40 degrees is equal to divide the opposite side to the angle of 40 degrees (AC) by the hypotenuse (AB)

so

sin(40\°)=AC/AB

Solve for AC

AC=(AB)sin(40\°)

substitute the given value

AC=(20)sin(40\°)

AC=12.9\ cm

therefore

The value of b is 12.9 cm

<em>Find the value of a</em>

we know that

in the right triangle ABC

The function cosine of angle of 40 degrees is equal to divide the adjacent side to the angle of 40 degrees (BC) by the hypotenuse (AB)

so

cos(40\°)=BC/AB

Solve for BC

BC=(AB)cos(40\°)

substitute the given value

BC=(20)cos(40\°)

BC=15.3\ cm

therefore

The value of a is 15.3 cm
