Find the value of x. Round to the nearest tenth.

Mathematics
1 answer:
Nezavi [6.7K]2 years ago
7 0

Answer:

x ≈ 55.6

Step-by-step explanation:

Using the sine ratio in the right triangle

sin20° = \frac{opposite}{hypotenuse} = \frac{19}{x} ( multiply both sides by x )

x × sin20° = 19 ( divide both sides by sin20° )

x = \frac{19}{sin20} ≈ 55.6 ( to the nearest tenth )

A portion of a map with cities a and b is shown.The map uses a scale of 1 inch to 30 miles. A new map has a scale of 2 inches=15
Alina [70]

Answer:

22.5miles

Step-by-step explanation:

For Map 1;

1 inches = 30miles

For Map 2:

2 inches = 15miles

1 inches = x

2x = 1 *15

x = 15/2

x = 7.5miles

This means that 1 inch represents 7.5miles on Map 2'

The distance between the two cities in miles = 30miles - 7.5miles

The distance between the two cities (in miles) = 22.5miles

After the first term in a sequence, the ratio of each term to the preceding term is r. If the first term is a, what is the third
irinina [24]

Answer:

The 3rd term is

ar^2

Step-by-step explanation:

From the given information, the first term of the sequence is

a_1=a

The common ratio of the sequence is

r

The explicit formula for a geometric sequence is :

a_n=a_1(r^{n-1})

To find the third term, we put n=3 to get:

a_n=a(r^{3-1})

This simplifies to:

a_3=ar^2

PLEASE HELP!!!!
Nadya [2.5K]

Answer:

(-1,1,3)

Step-by-step explanation:

midpoint = (x1+x2/2, y1+y2/2, z1+z2/2)

midpoint = ( (-6+4)/2, (3+-1)/2, (4+2)/2 )

midpoint = (-2/2, 2/2, 6/2)

midpoint = (-1, 1, 3)
