Number 19 you are comparing one measurement to another. Since it says 1/2 inch equals 4 ft, we want to find out how many more inches are needed if the given scale was 2/3 = 4 ft. Now lets find a common denominator for both scales stated in inches. We have 2/3 inch and 1/2 inch. Our denominator are the bottom parts of the fraction where we need to find a common factor for the denominator so we can add or subtract fractions. We have a 3 and a 2. You may always use the multiplication between two denominators to find a common factor such as 3 times 2 which equals 6 for both denominators. Now we multiplied the 3 by 2 to get 6 so the top part (numerator needs to be multiplied the the 2 because we changed the bottom part by 2 as well. You should notice that when you reduce your fraction now 4/6 is 2/3. Just a self check example there. As for 1/2 we multiplied a 3 to get 6 for the denominator so we need to multiply the numerator by 3 as well. You now should have 4/6 and 3/6. Since the question asks for how many more inches we need to subtract 4/6 from 3/6 and we get 1/6 inch for our answer.

Simplify the expression. -2/3c -9/5 + 14c + 3/10

Andrew [12]

Answer:

$13 \frac{1}{3} c - 1 \frac{1}{2}$

Step-by-step explanation:

We want to combine alike terms so

-2/3c+14c & -9/5+3/10

14c-2/3

$\frac{14}{1} c - \frac{2}{3} c$

Multiply 14/1 by 3/3 to get the denominators the same

$\frac{42}{3} c - \frac{2}{3} c$

Subtract

$\frac{40}{3} c$

simplify

$13 \frac{1}{3} c$

now

$\frac{3}{10} - \frac{9}{5}$

Multiply 9/5 by 2/2

$\frac{3}{10} - \frac{ 18}{10}$

Subtract

$- \frac{15}{10}$

Simplify

$- 1 \frac{1}{2}$

put both together

$13 \frac{1}{3}c - 1 \frac{1}{2}$

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

An advertising blimp hovers over a stadium at an altitude of 125 m. The pilot sights a tennis court at and 8° angle of depressio

tatuchka [14]

Answer:

Hence the ground distance is about 889m between stadium and Tennis court.

Step-by-step explanation:

Given:

A pilot at height of 125 m(flying the advertising blimp)

angle of depression=8 degrees.

To find :

The ground distance stadium and tennis court.

Solution :

Using Trigonometric Function we can solve it ,

(Refer the attachment for fig)

Considering above data we get a triangle(ABC)

with point A represent pilot position and C court position and B as stadium.

The height AB=125 m

angle of depression= 8 degrees.

Using

<em>tan∅ =AB/BC</em>

tan(8)=125/BC

BC=125/tan(8)

=125/0.14054

=889.2

=889 m

Hence the ground distance is about 889m between stadium and Tennis court.
