Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{ - 55}}}}}

Step-by-step explanation:

Given, a = -6 , b = -5

\sf{5a + 5b}

plug the value of a and b

⇒\sf{5 \times ( - 6) + 5 \times ( -5)}

Multiply the numbers

⇒\sf{ - 30 + ( - 25)}

We know that , \sf{( + ) \times ( - ) = ( - )}

⇒\sf{ - 30 - 25}

Calculate

⇒\sf{ - 55}

Hope I helped!

Best regards! :D

Answer:

1. B 2. B 3. D 4. A 5. A 6. A 7. B 8. C

Step-by-step explanation:

1. 6 and 8 are right next to each other. Making them 'adjacent angles' as 'adjacent' means 'next to'

2. 2 and 3 are vertically opposite angles, and these angles are equal to each other

3. 3 and 6 are alternate angles. These angles form a 'Z' shape

4. Similar to q2, 1 and 4 are vertically opposite angles

5. Yes they are similar because there are two angles which equal

6. The angles of the big triangle will correlate to the small triangle, therefore x is 40

7. Similar triangles will have the same angles. The top angle of the small triangle is 60, as stated in the big triangle, and 70 is given. The sum of interior angles of a triangle is 180. So, add 60 and 70, then minus from 180

8. Again, same concept as q7, the angles are given to you and you just need to correspond each angle to its respective area, then minus the total of the two given angles from 180

Hope this helped you!!

The odds against Carl beating his friend in a round of golf are 9:7. Find the probability that Carl will lose?
grandymaker [24]

The ratio 9:7 gives you following statement:

  • Carl will win in 9 cases from 9+7=16;
  • Carl will lose in 7 cases from 16.

Then the probability that Carl will lose is

Pr(\text{Carl will lose})=\dfrac{7}{16}.

Answer: Pr(\text{Carl will lose})=\dfrac{7}{16}.
