Answer:

7. 7.1+5.4+2.9=15.7

10.3+5.4=15.7

8. 373.4 - 152.9 = 220.5

373.4 - 153 = 220.4

220.4 - 0.1 = 220.5

9. 18.25 + 7.99 + 4.75 = 30.99

10. 1.05 + 3 + 4.28 + .95 = 9.28

11. 302.504

The vertex angle of an isosceles triangle measures 26° . The base is 30 units long. What is the length of a leg of the isosceles
sergejj [24]

Answer:

65.46 units

Step-by-step explanation:

Given the information:

  • The vertex angle of an isosceles triangle measures 26°

=> the leg angle is:

= (180°  - 26° )/2

= 77°

  • The base is 30 units

Let x is the length of the leg side (x>0)

We use cosine law to find x, we have:

30^{2} = x^{2} +x^{2} -2xxCos(26) Because the  isosceles has two equal leg sides

<=> 30^{2} = 2x^{2} - 1.79x^{2}

<=> 0.21x^{2}  = 30^{2}

<=> x^{2} =4285

<=> x = 65.46 units

Hope it will find you well.

Blake and two friends equally shared the cups of water shown in the picture.
3241004551 [841]
The answer would be c- 2/6

there are six cups total and three (blake plus two others) friends

there are two ways you can solve this…

1. by making groups
if you look at the picture, you can split it into three groups because that is the number of people, then count how many cups there are in one group which will be your numerator for the denominator six which is the total

2. simple division
divide the total number of cups buy the number of people which is 3
you get two and follow the same process above

lora16 [44]

Answer:

9

41/4

23/2

51/4

14

Step-by-step explanation:

The first term is the first term that is given. Just copy it.

Each next term is the previous term plus the common difference.

First term: a_1 = 9

Second term: a_2 = 9 + 5/4 = 36/4 + 5/4 = 41/4

Third term: a_3 = 41/4 + 5/4 = 46/4 = 23/2

Fourth term: a_4 = 46/4 + 5/4 = 51/4

Fifth term: a_5 = 51/4 + 5/4 = 56/4 = 14
