Gabriella plays video games from 2:49 P.M. To 3:32 P.M. Mason plays video games for 35 minutes. How many minutes longer does Gab

Mekhanik [1.2K]

Answer:

Mizuki here to help!

8 minutes longer will be the correct answer!

Step-by-step explanation:

First, let's find out how many minutes Gabriella played:

3:32 - 2:49 = 2:92 - 2:49 = 0:43

Check:

2:49 + 0:43 = 2:92 = 3:32

It's correct so...

43 - 35 = 8

Hope this helped!

Mrs.Klein made some fruit buns.She sold 3/5 in the morning and 1/4 of the remainder in the afternoon.If she sold 200 more fruit

fredd [130]

3/5 =6/10, so 6/10-1/10 = 5/10 =200. 1/2 of 200=100, so mrs.kleein made 400 fruit buns in all.

Find the exact values of a) sec of theta b)tan of theta if cos of theta= -4/5 and sin<0

Gre4nikov [31]

Answer:

Using trigonometric ratio:

$\sec \theta = \frac{1}{\cos \theta}$

$\tan \theta = \frac{\sin \theta}{\cos \theta}$

From the given statement:

$\cos \theta = -\frac{4}{5}$ and sin < 0

⇒ $\theta$ lies in the 3rd quadrant.

then;

$\sec \theta = \frac{1}{-\frac{4}{5}} = -\frac{5}{4}$

Using trigonometry identities:

$\sin \theta = \pm \sqrt{1-\cos^2 \theta}$

Substitute the given values we have;

$\sin \theta = \pm\sqrt{1-(\frac{-4}{5})^2 } =\pm\sqrt{1-\frac{16}{25}} =\pm\sqrt{\frac{25-16}{25}} =\pm \sqrt{\frac{9}{25} } = \pm\frac{3}{5}$

Since, sin < 0

⇒ $\sin \theta = -\frac{3}{5}$

now, find $\tan \theta$ :

$\tan \theta = \frac{\sin \theta}{\cos \theta}$

Substitute the given values we have;

$\tan \theta = \frac{-\frac{3}{5} }{-\frac{4}{5} } = \frac{3}{5}\times \frac{5}{4} = \frac{3}{4}$

Therefore, the exact value of:

(a)

$\sec \theta =-\frac{5}{4}$

(b)

$\tan \theta= \frac{3}{4}$
