This giant banana is 8 inches long. How many 0.4 inch slices of banana can be cut from this giant banana

lyudmila [28]

Answer:

0.4 inch slices of banana can be cut from this giant banana is, 20

Step-by-step explanation:

Given that:

The giant banana is 8 inches long.

⇒Length of giant banana = 8 inches

We have to find how many 0.4 inch slices of banana can be cut from this giant banana.

$\text{Number of slices of banana} = \frac{8}{0.4}$

⇒ $\text{Number of slices of banana} = \frac{80}{4}$

Simplify:

$\text{Number of slices of banana} =20$

Therefore, 0.4 inch slices of banana can be cut from this giant banana is, 20

Angle (theta) is in standard position. If (8,-15) is on the terminal ray of angle (theta), find the values of the trigonometric

mariarad [96]

Answer:

$\sin \theta =\frac{-15}{17}\\cos \theta =\frac{8}{17}\\\tan \theta =\frac{-15}{8}\\\csc \theta =\frac{-17}{15}\\\sec \theta =\frac{17}{8}\\\cot \theta =\frac{-8}{15}$

Step-by-step explanation:

Given: (8,-15) is on the terminal ray of angle

To find: All the trigonometric ratios

Solution:

Trigonometry is a branch of mathematics that explain relationship between the sides and angles of triangles.

If (x, y) lies on the terminal side of θ then $r=\sqrt{x^2+y^2}$

$r=\sqrt{(8)^2+(-15)^2}=\sqrt{64+225}=\sqrt{289}=17$ units

$\sin \theta =\frac{y}{r}=\frac{-15}{17}\\cos \theta =\frac{x}{r}=\frac{8}{17}\\\tan \theta =\frac{y}{x}=\frac{-15}{8}\\\csc \theta =\frac{1}{\sin \theta }=\frac{-17}{15}\\\sec \theta =\frac{1}{cos \theta}=\frac{17}{8}\\\cot \theta =\frac{1}{\tan \theta}=\frac{-8}{15}$

Of a journey of 216km, 56km were on untarred road. for this part of the journey, a motorist could only average 28km/h. if his av

kenny6666 [7]

Answer:

64 km/hr

Step-by-step explanation:

216 - 56 = 160 km on good road

216km / 48 km/hr = 4.5 hours total time

56 km / 28 km/hr = 2 hours on bad road

then 2.5 hours on good road ( for total 4.5 hrs)

160 km / 2.5 hr = 64 km/hr on the good road portion
