In 2015, there were approximately 31,800 firearms fatalities. Express this quantity in deaths per hour

1 answer:

8 0

I could be wrong, but just divide 31,800 by 365 which would give you the number of fatalities each day, then divide that number by 24. that should give you the number of deaths in an hour. Again, could be totally wrong.

q / 12 = sin 20
q = 12 sin 20
q = 4.1

p / 12 = cos 20
p = 112 cos 20
p = 11.3

17)

x / 44 = tan 39
x = 44 tan 39
x = 35.6

35.6 / y = sin 39
y = 35.5 / sin 39
y = 56.4

18)

14 / b = sin 57
b = 14 / sin 57
b = 16.7

a / 16.7 = cos 57
a = 16.7 cos 57
a = 9.1

If isosceles triangle ABC has a 130° angle at vertex B, which statement must be true?

scZoUnD [109]

Answer:

Option B m<ZA+m<ZB = 155° is correct option.

Step-by-step explanation:

We know that sum of angles of triangle is equal to 180°

And Isosceles triangle, 2 angles are same

So, let Angle 1 = x

Angle 2 = x

Angle 3 = 130°

Finding values of angle x

x+x+130=180

2x=180-130

2x=50

x=25

So, Angle 1 = 25 °

Angle 2 = 25°

As, angle B is greater than 90°, the sum of angles added must be greater than 90°

So, Option A, C and D can't be correct, as their sum is less than 90°

Option B m<ZA+m<ZB = 155° is correct option.

Verify:

m<ZA = 25° (as found earlier)

m<ZB = 130° (given)

So, m<ZA+m<ZB = 155°

25°+130° = 155°

Megan earns $20.00 by walking dogs. She uses all of her earnings to buy a shirt for $12.85 and some stickers for $0.65 each. How

Leya [2.2K]

The answer is B: 11.

To solve it, you need to solve the equation: 20.00=12.85+0.65x
