S is inversely proportional to t . When s = 0.5 , t = 7 Work out t when s = 5
shtirl [24]

Answer:

t = 0.7

Step-by-step explanation:

s = k/t  where 'k' is the constant of variation

given:  0.5 = k/7 so k = 3.5

5 = 3.5/t

5t = 3.5

t = 0.7

In Exercises 3 and 4, find the values of x and y <br> plz help!!!
jonny [76]

Answer:

x = 20°

y = 30

Step-by-step explanation:

The triangle given on close inspection, it is an equilateral triangle.

Each angle in an equilateral triangle is equal. Likewise, each side is equal.

Thus;

16 + y = 46

y = 46 - 16

y = 30

The triangle that has angle 80°, the other complete angle is 60° because it's an angle of an equilateral triangle.

Thus, the smaller angle there is;

180 - (80 + 60) = 40°

Because sum of angles in a triangle is 180°

Now, x + 40 = 60°

Since that's also an angle of an equilateral triangle.

x = 60 - 40

x = 20°

Find a.<br> Round to the nearest tenth:<br> 2 cm<br> с<br> 150<br> 1050<br> a =<br> = [? ]cm
VLD [36.1K]

Answer:

a = 1.8 cm

Step-by-step explanation:

Here. we want to find the value of a

To do this, we are going to use the sine rule

it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle

From the diagram, we have that;

The angle facing a is;

180-15-105 = 60

So, we have that

a/sin 60 = 2/sin 105

a = 2sin 60/sin 105

a = 1.794 cm
