Answer:

z = 123.9

Step-by-step explanation:

We can use trigonometric functions, because we have a right triangle.  We now the adjacent and opposite side of the angle we are interested in, so we can use the tan function.

tan 20 = opposite/ adjacent

tan 20 = 45.1/z

Multiply each side by z

z* tan 20 = 45.1 /z * z

z * tan 20 =45.1

Divide each side by tan 20

z = 45.1 / tan 20

z=123.9112316

To one decimal place,

z = 123.9

The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a,
omeli [17]
<span>f = v + at

Subtract v from both sides.

f - v = at

Divide both sides by a.

(f - v)/a = t

Switch sides.

t = (f - v)/a

t = \dfrac{f - v}{a}</span>

Marcus needs 3 1/10 m of blue fabric and 1 1/5 m of yellow fabric to make his costume. How much more blue fabric than yellow fab
Kamila [148]

Answer:

1\frac{9}{10}\ m

Step-by-step explanation:

we know that

To find out how much more blue fabric than yellow fabric does Marcus need, subtract the quantity of yellow fabric from the quantity of blue fabric

step 1

Convert mixed number to an improper fraction

3\frac{1}{10}\ m=\frac{3*10+1}{10}=\frac{31}{10}\ m

1\frac{1}{5}\ m=\frac{1*5+1}{5}=\frac{6}{5}\ m

step 2

Subtract the numbers

\frac{31}{10}-\frac{6}{5}=\frac{31}{10}-\frac{12}{10}=\frac{19}{10}\ m

Convert to mixed number

\frac{19}{10}\ m=\frac{10}{10}+\frac{9}{10}=1\frac{9}{10}\ m
