Step-by-step explanation:
Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?
Answers
She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:
2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276
So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.
To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.
- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.
So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.
Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.
Answer:280 in
Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.
Answers
Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given that Jacinta says that the product of a rational number and an irrational number is always irrational.
Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.
Therefore, Jacinta's claim is wrong.

The half-life of a certain radioactive element is 35 hours. If there are 904 grams of this element, how much will be left after 70 hours? PLEASE HELP I MIGHT FAIL MATH.
Answers
===========================================================
Explanation:
The half-life is 35 hours. This means every 35 hours, the amount of the substance is cut in half. If we started with 100 grams, then 35 hours later, we will have 50 grams. Then another 35 hours later we will then have 25 grams, and so on.
In this case, we start with 904 grams and follow this sequence:
904, 452, 226, 113, ...
Each term is cut in half. Going from term to term it takes 35 hours each. The third term 226 is the result of waiting two half-lives, which is 2*35 = 70 hours that have elapsed total.
--------------
If you want to use a formula, then it would be
\(y = A*\left(\frac{1}{2}\right)^{x/H}\)
where,
H = half-life duration (in this case, it is 35)
A = starting amount (which is 904 in this case)
x = amount of time that has elapsed (we will plug in x = 70)
y = final amount after x units of time has elapsed
note that x and H must have the same time unit. Both are in terms of hours in this case.
------------
So we will plug A = 904, x = 70, H = 35 into the formula to get...
\(y = A*\left(\frac{1}{2}\right)^{x/H}\\\\y = 904*\left(\frac{1}{2}\right)^{70/35}\\\\y = 904*(0.5)^{2}\\\\y = 904*(0.25)\\\\y = 226\\\\\)
We see that x = 70 leads to y = 226. This means after 70 hours, there is 226 grams of the material left.

The second option, x + y.
Explanation: the value of x is -5/6. The value of y is 4/3. When you add them together, you will result in a positive value:
Since -5/6 and 4/3 don’t share the same denominator, you have to make them the same by finding the “common denominator.” In this question, the common denominator is 6 because 6 and 3 can both be multiplied by a value to get 6 (6 x 1 = 6 and 3 x 2 = 6)
Now, you have to make both of the denominators 6. -5/6 already has a denominator of 6, so it doesn’t change. 3 has to be multiplied by 2 to get 6. But remember, whatever you do to the top, you have to do to the bottom. So 4/3 will be changed into 8/6.
Now you can just add. Remember that the denominator doesn’t change, so just keep it 6. Don’t do 6 + 6.
-5 + 8 = 3
x + y = 3/6, or 1/2. Which is a positive value. Therefore, the answer is the second option, x + y.

The equation of a plane which passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5) is given by?
Answers
Answer: We can find the equation of a plane in point-normal form, which is given by:
Ax + By + Cz + D = 0
where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.
To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:
v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >
The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>
So the normal vector is given by:
n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k
Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:
A2 + B-3 + C*1 + D = 0
-142 + -7-3 + -11*1 + D = 0
-28 - 21 - 11 + D = 0
D = 58
So the equation of the plane is :
14x - 7y - 11z + 58 = 0
This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

FOR # 13-#14: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100.

14. Graph your inequality from #13 on a number line.
15. For n(34-n) <111, check whether n = -3 is a solution.
SOLUTION? (Yes or No)______
Answers
Answer:
13) x ≥ 50/3
14) see attached graph
15) Yes
Step-by-step explanation:
The equation relating the number of sales and pay is given by
y = 50 + 3x where x is the number of sales.
Q 13
If you need your pay to be exactly 100 then the above equation translates to 50 + 3x = 100
If you want the sales to be at least 100 then the above equation becomes an inequality 50 + 3x ≥ 100
We can re-write this as x ≥ 50/3
Q 14
See attached graph
x = 50/3 is a vertical line passing intersecting the x axis at x = 50/3(16.67)
All values of x ≥ 16.67 forms the region for the inequality
Q 15
Substitute -3 for n in the equation n(34-n) and check whether it satisfies the inequality
(-3)(34 - (-3)) = (-3)(37) is a negative number. (You don't actually have to calculate it but it works out to -111. ) Therefore it satisfies the inequality
