Step-by-step explanation:
98+38+74=210
210 divided by 100= 2.1
2.1 times 7.5= $15.75
Sandy will pay $15.75 dollars in tax
Answer:
342 grams of sugar are needed.
Step-by-step explanation:
This really should be in chemistry. Math types may not know any chemistry.
Step One
Find the number of moles needed in a solution of the givens.
<em><u>Givens</u></em>
V = 2.00 L
C = 0.500 moles / Liter
<em><u>Formula</u></em>
n = C * V
<em><u>Sub and Solve</u></em>
n = 2 * 0.5 = 1 mole
Since you need just 1 mole, the answer is 342 grams of sugar are needed to put into a solution of 2 Liters with a concentration of 0.500
The answer is to 3 decimal places so 342 is the answer.
Answer:
its parallel!!!!!
its parallel because they have different slopes!!!
Answer:
m∠BOC = 40°
Step-by-step explanation:
Given O A ‾ ⊥ O C ‾ OA ⊥ OC m∠BOC=6x−6 ∘
m∠AOB=5x+8 ∘
Find m ∠ B O C:
This means that: m∠BOC and m∠AOC intersect at a right angle.
Hence:
m∠BOC + m∠AOC = 90°
Step 1
Solving for x
6x - 6 + 5x + 8 = 90°
11x -2 = 90°
11x = 90 - 2
11x = 88
x = 88/11
x = 8
Step 2
Solving for m∠BOC
m∠BOC = 6x - 8
m∠BOC = 6(8) - 8
= 48 - 8
= 40°
