To make the bowling team. Jacques needs a three-game average of 160. If he bowled 141 and 162 for the first two games, what scor

e S must be obtained in the third game so that his average is at least 160?

(141 + 162 + S) / 3 = 160

(303 + S) / 3 = 160

101 + S/3 = 160
-101 -101
S/3 = 59
*3 *3

S= 177

Jacques needs at least a 177 to get a 160 average

Lines a and b are parallel.

I have added a screenshot with the complete question along with a diagram representing the scenario.

<u><em>Answer:</em></u>
s = 22°

<u><em>Explanation:</em></u>
<u>1- getting the top right angle of line B:</u>
We are given that:
the top right angle of line A = 158°
Since lines A and B are parallel, therefore, the top right angle of line A and the top right angle of line B are corresponding angles which means that they are equal
This means that:
<u>Top right angle of line B = 158°</u>

<u>2- getting the value of s:</u>
Now, taking a look at line B, we can note that:
angle s and the top right angle form a straight angle. This means that the sum of these two angles is 180°
Therefore:
180 = s + 158
s = 180 - 158
<u>s = 22°</u>

Hope this helps :)

It would be an average of about 8.00 (7.99 to be somewhat exact). You get this by dividing the total amount by 200, the dividing that by 363.

One bag contains three white marbles and five black marbles, and a second bag contains four white marbles and six black marbles.

Troyanec [42]

It will be 21/40

probability getting both white marbles

3/8×4/10=12/80

probability getting both black marbles

5/8×6/10=30/80

12/80+30/80=42/80= 21/80

Pie

Average speed = $\frac{Total Distance}{Total Time}$

Ishan's Speed uphill = 10mph

Time taken = 18 minutes = 18/60 = 3/10 hours

Now distance = rate × time

Distance traveled by Ishaan up hill = 10 × 3/10 = 3 miles

Now returning back home

Distance = 3 miles

Rate = 30 mph

So time taken = distance/ rate = 3/30= 1/10 hours = 1/10 ×60 = 6 minutes.

Now total distance traveled = 3 + 3 = 6 miles

Total time taken = 18 + 6 = 24 minutes = 24/60 = 2/5 hours

Average speed

= $\frac{6}{0.4}$

= 15 mph

Ishaan's average speed for the entire trip from home to the gift store and back is 15mph
