Solve the right triangle. Round decimal answers to the nearest tenth.

Mathematics
1 answer:
AnnZ [28]3 years ago
5 0

Answer:

See solution below

Step-by-step explanation:

According to pythagoras theorem

hyp^2 = opp^2 + adj^2

10^2 = 4^2 + b^2

100 = 16 + b^2

b^2 = 100-16

b^2 = 84

b = √84

b ≈ 9

Using SOH CHA TOA identity

sin B = AC/AB

Sin B = 9/10

B = arcsin0.9

B ≈ 64degrees

sinA = BC/AB

Sin A = 4/10

A = arcsin0.4

A ≈ 24degrees

Multiply. Write the answer in simplest form.
Roman55 [17]

Answer:

88,306

Step-by-step explanation:

Multiplying times 7 steps:

Step 1. 8 x 7 = 56  

Step 2. 1 x 7 = 7

Step 3. Add the 5 from step 1. 7 + 5 = 12

Step 4. 3 x 7 = 21

Step 5. Add the 1 from step 3. 21 + 1 = 22

Step 6. 1 x 7 = 7

Step 7. Add the 2 from step 5. 7 + 2 = 9

Equals = 9226

Steps for times 6:

Step 1. 6 x 8 = 48

Step 2. 1 x 6 = 6

Step 3. Add the 4 from step 3. 6 + 4 = 10

Step 4. 3 x 6 = 18

Step 5. Add the 1 from step 3. 18 + 1 = 19

Step 6. 1 x 6 = 6

Step 7. Add the 1 from step 5.

Equals = 79080

Now add the two 9226 + 79080 = 88, 306

Took me a while to work out and explain lol.

Brad wants to open a new savings account. He finds one that returns 3% on his investment each year. Use the variable to write a
Jet001 [13]
Return rate, r = 3% = 0.03
x = initial investment
b = final balance

After 1 year, the balance i
b = initial investment + interest
b = x + r*x = (1 + r)*x

Because r = 0.03,
b = 1.03x   (after 1 year)
