Answer:
tax = .45
total cost = 4.95
Step-by-step explanation:
The price before tax is 4.50
The tax rate is 10%
The tax is
4.50 * 10%
4.50 * .10
.45
Add the tax of .45 to the total price
4.50 + .45 = 4.95
Answer:
17.2°
Explanations
To find angle A, use the cosine rule.
a^2 = b^2 + c^2 - 2 × a × c cos A
4^2 = 7^2 + 10^2 - 2 × 7 × 10 cos A
16 = 49+ 100 - 140 × cosA
16 = 149 - 140cosA
16- 149 = - 140cosA
-133 = - 140cosA
cosA = 133/140
cosA = 0.95
A = 17.2°
Answer:
7B+8N<120
Step-by-step explanation:
The total amount of the bracelets and necklaces is less than $120, so if you add the price of each necklace ($8) and the price of each bracelet ($7), it will be <$120.

Step-by-step explanation:
Answer:
- 24
Step-by-step explanation:
4(m + 2p) ← substitute m = 2 and p = - 4 into the expression
= 4(2 + 2(- 4) )
= 4(2 - 8)
= 4(- 6)
= - 24
