Answer 1

Answer:

1. 74.6° = m∠C 65.4° = m∠A a = 2.83

2. Triangle does not exist

Step-by-step explanation:

1. Use the law of sines to find m∠C

sin 40/2 = sin C/3

3sin 40/2 = sin C = .96418...

arcsin .96418... = 74.6° = m∠C

m∠A = 180 - 40 - 74.6 = 65.4°

a/sin 65.4 = 2/sin 40

a = 2 sin 65.4/sin 40 = 2.83

2. sin 95/4 = sin C/5

5sin 95/4 = sin C = 1.2452... which is impossible since the cosine of an angle is ≤ 1

To multiply a decimal number by 102, move the decimal point

Answers

Answer:

two digits to the right

Step-by-step explanation:

When multiplying a decimal by 102 you would need to move the decimal point two digits to the right. This is because we are multiplying by a hundred number. When multiplying any whole positive number by a decimal, we need to move the decimal point to the right one less than the amount of digits that the positive whole number has. For example, a thousand (1000) has 4 digits so we move the decimal point of the product to the right by 3.

Examples:

102 * 0.02 = 2.04

1000 * 0.02 = 20

10000 * 0.02 = 200

Cars A and B leave the same place and travel in the same direction along a straight road. Car A travels at 60 km/h and car B travels at 72 km/h. After how long will they be at 8km apart?

Answers

Answer:

Car A: 8 minutes

Car B: 6.67 minutes

Step-by-step explanation:

Car A: 60km evrery hour so,

1 km every minute, so he will be in 8km in 8 minutes.

Car B: 72km per hour so,

72/60 = 1.2 = 1.2 km per minute.

8/1.2 = 6.6666666666667 which is about 6.67 to the nearest hundredth.

Answer:

40 min

Step-by-step explanation:

Car A is traveling at 1 km/min (60/60)

Car B is traveling at 1.2 km/min (72/60)

Car B gains .2km on Car A for every minute they drive.

8km/.2 = 40

Mary Jo spends $1,450 to buy stock in two companies. She pays $15 a share to one of the companies and $20 a
share to the other. If she ends up with a total of 90 shares, how many shares did she buy at $15 a share and how
many did she buy at $20 a share?

Answers

Answer:

she bought 70 shares of the $15 shares

she bought 20 shares of the $20 shares

Step-by-step explanation:

this would be solved using simultaneous equation

let a = $15 shares

b = 20 shares

a + b = 90 equation 1

15a + 20b = 1450 equation 2

Multiply equation 1 by 15

15a + 15b = 1350 equation 3

subtract equation 3 from equation 2

5b = 100

b = 20

substitute for b in equation 1

20 + a = 90

a = 70

How long is the shorter leg of the triangle?

Answers

Base is 12 and height is 24

Answer:

Step-by-step explanation:

36 m^2 = bh/2

72 = bh

72 = 12·6

check

36 m^2 = 12·6/2

36 = 36

2. 2/1 so run is 1

3. its positive since slope is positve

4. y int is when x is 0 and y has value so y int is 1
