Calculate sin a=0.34

Answers

sina=0.34 has already been calculated for us, but to calculate the angle, which is what I'm assuming you want to know, we must take the inverse trigonometric function of sin. 

From: sina=0.34, we can derive that:

a=sin ^(-1) 0.34

Using a scientific calculator to solve this, we can see that the degrees that a is equal to (rounded to the nearest degree) is: 

a=20°

Which one of the following statements expresses a true proportion? A. 2 : 3 = 3 : 2
B. 3 : 5 = 12 : 20
C. 14 : 6 = 28 : 18
D. 42 : 7 = 6 : 2

Answers

Try them step by step 

2/3=3/2? No

3/5=12/20? Lets try and see

If we simplify 12/20 what do we do? Well we take 4*3=12 and 4*5=20 

Now that we simply the 4 from both the numerator and denominator we get our answer 3/5 

Your answer will be B.

The temperature at a mountain base camp was −2 degrees Celsius on Thursday. Friday morning, the temperature was 1 degree Celsius lower than what it was on Thursday. By Friday evening, the temperature was 3 degrees Celsius lower than what it was that morning. What was the temperature at the base camp Friday evening?

Answers

The temperature at the base camp on Friday evening was -6°C

The temperature at a mountain base on Thursday = -2°C

On Friday morning, the temperature was 1 degree Celsius lower than what it was on Thursday, hence:

The temperature at a mountain base on Friday morning = -2°C - 1°C = -3°C

By Friday evening, the temperature was 3 degrees Celsius lower than what it was that morning.

The temperature at a mountain base on Friday evening = -3°C -3°C = -6°C

The temperature at the base camp on Friday evening was -6°C

2/7 x 35 =

Answers

If you would like to calculate 2/7 * 35, you can do this using the following steps:

2/7 * 35 = 2 * 35/7 = 2 * 5 = 10

The correct result would be 10.

a landscaper is designing a flower garden in the shape of a trapezoid. she want to make to shorter base 3 yards greater than the height and the longer base 7 yards greater than the base. she wants the area 295 square yards. the situation is modeled by the equation h^2+5h=295. use the quadratic formula to find the height that will give the desired area

Answers

we know that

The formula to calculate the solutions of the quadratic equation of the form ax^(2) +bx+c=0  is equal to

x=\frac{-b(+/-)\sqrt{b^(2)-4ac}}{2a}

in this problem we have

h^(2) +5h=295

equate to zero

h^(2) +5h-295=0

a=1\ b=5\ c=-295

substitute in the formula

x=\frac{-5(+/-)\sqrt{5^(2)-4(1)(-295)}}{2*1}

x=(-5(+/-)√(25+1,180))/(2)

x=(-5(+/-)√(1,205))/(2)

the positive solution is

x=(-5+√(1,205))/(2)=14.86\ yd

therefore

the answer is

The height is 14.86\ yd
put you formula in this way:  ax^2+bx+c=0 this is  h^2+5h-295=0
Now solve with the second grade equation
a=1, b=5, c=-295
you will get h=14.86 and h=-19.86, you can not have negative numbers so the only answer is 14.86
