4. k less than 3.5, so a number k is being taken away from 3.5:
The answer is 3.5-k

5. the sum of g and h, reduced by 11, so you need a set of parentheses to write this one: (g+h)-11

6. 5 less than y, plus g, so do a combination of the strategies used in the previous two problems and you will get: (y-5)+g

7. 5 less than the sum of y and g, you are taking away 5 from the sum of two numbers, y and g, so: (y+g)-5

Hope this helps :-)

Find tan theta if theta is an angle in standard position and the point with coordinates (4,3) lies on the terminal side of the a

Karolina [17]

Answer: 0.75

Step-by-step explanation:

We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.

We now have a triangle with the values of:

x = 4

y =3

h^2= 4^2 + 3^2

h^2 = 16 + 9

h^2 = 25

h = 5

h = 5

Tangent = opposite/adjacent

= y/x

= 3/4

= 0.75

I need the answer to these math questions.

Studentka2010 [4]

Answer:

1) 506.85 minutes

2) 17.33 minutes

3) 23.25 hours

Step-by-step explanation:

1) 16 minutes and 21 seconds

$21\ seconds=\frac{21}{60}\\=0.35\ minutes$

16 minutes and 21 seconds=16.35 minutes

Multiply by 31

$\therefore 16.35\times 31=506.85\ minutes$

2) 537 minutes 20 seconds

$20\ seconds=\frac{20}{60}\\=0.33\ minutes$

537 minutes 20 seconds=537.33 minutes

Divide by 31

$\therefore 537.33\div 31=17.33\ minutes$

3) 999 hours 45 minutes

$45\ minutes=\frac{45}{60}\\=0.75\ hours$

999 hours 45 minutes=999.75 hours

$\therefore 999.75\div 43=23.25\ hours$

Use any method you like to find the measure of angle A

lutik1710 [3]

A = 71.5 degrees (1 dp)

cos(A) = (21^2 + 16^2 - 22^2) / (2 x 21 x 16)
= 0.31696...
A = cos^-1(0.31696...) = 71.5 degrees
