Answer:
24 cubic inches
Step-by-step explanation:
Whenever you are finding the volume you have to multiply by two plus a number times two. For example, since there is two depths, you have to multiply 3 by 2 plus the next number. Then, since there is two sides, you multiply 5 by 2 plus the next number. Finally, since there is only one base, you don't have to multiply by two.
(3×2)+(5×2)+8=24
Hope I explained well enough for you to understand.
It is sometimes true because it isn't always that whey
Answer: x = -29
Step-by-step explanation:
-0.59x+0.39x=5.8
Collect like terms
-0.2x = 5.8
Divide both sides of the equation by -0.2
x = -29
Response to user in comments:
-0.59+0.39=-0.2 that is a fact
-0.2/-0.2=1 that is a fact
5.8/-0.2= - 29 that is a fact
These are the facts about the steps of the equation. Solving Steps for Solving the Equation
<span>ME = 1.10.
Explanation:
The margin of error, ME, is given by the formula z*(</span>σ<span>/</span>√<span>n).
Since we want a 90% confidence interval, z=1.645.
</span>σ<span>=6, and n=80, giving us ME=1.645*(6/</span>√<span>80). This comes out to 1.10.</span>
Answer:
The total cost of the meal is $58.56.
Step-by-step explanation:
The question is asking for problem solving with percentages. In order to multiply by a percentage, we must first convert the percentage to a decimal by diving the percent by 100. Since the Hu family is going to leave a 15% tip on the pre-tax amount of $48, we will need to multiply 48 x .15 = $7.20. The Hu family must also pay a 7% sales tax on the cost of the meal. In order to find the cost of the meal, including tax, we take the price of 48 x 1.07 = $51.36, which would be the original cost plus an additional 7% tax. Lastly, we would need to include the tip to the post-tax total: $51.36 + $7.20 = $58.56.
