Hi there! Let me know if you have any questions about my answer:

5.6 cm³

Step-by-step explanation:

For this problem, we can assume* that the ham did not have any salt before curing.

The questions tells us:

- The mass of the salt: 12 g

- The density of salt: 2.16 g/cm³

We are looking for:

- The volume of salt

Solve using dimensional analysis, or the "unit cancellation method":

Write an equation.

$V_{salt} = 12g * \frac{1 cm^{3}}{2.16g}$

Notice that the questions includes "cm³" in the units when discussing density. Volume can be given in cm³.

We want to multiply values with their units from the question so that, when the units cancel out, you will only have cm³ left.

In this equation set-up, "g" will cancel out because one is in the numerator (top number) and another is in the denominator (bottom number).

$= \frac{12g*1 cm^{3}}{2.16g}$ Both "g" units cancel out

$= \frac{12*1 cm^{3}}{2.16}$ Multiply 12 and 1 in the numerator

$= \frac{12 cm^{3}}{2.16}$ Divide 12 by 2.16 and keep the cm³ units

$= 5.55... cm^{3}$ Keep one extra digit** to help you round. The 5 in the middle rounds to 6.

$= 5.6 cm^{3}$ Final answer

*The ham is here to confuse you. The question doesn't give us enough information about the ham. We don't know how much ham there is, and we don't know how much salt was in the ham originally.

**12 has 2 significant figures. 2.16 has 3 significant figures. Since you're multiplying or dividing them together, you want the answer to round to 2 significant figures. Learn more about significant figures here: brainly.com/question/14463143

I hope this helps! Learn about another solution method, the density formula, here:

Hello there,
Part 1:
Perimeter of Red = 11+11+11+11
= 44
Perimeter of Blue= 6+6+6+6
= 24
Ratio: Red : Blue
44 : 24(divide by 4)
11 : 6
Part 2:
Area of Red= 11 x 11
= 121
Area of Blue= 6 x 6
= 36
Ratio: Red : Blue
121: 36

Hope this helps :))

Let R be the event that a randomly chosen person lives in the city of Raleigh. Let O be the event that a randomly chosen person

Anit [1.1K]

Answer:

P(O|R)

Step-by-step explanation:

The conditional probability notation of two events A and B can be written as either P(A|B) or P(B|A).

The '|' sign is read as 'given'. So, P(A|B) is read as the probability of event A given event B which implies that it is the probability that event A will occur given that event B has already occurred.

In the question,

Event R = Person lives in the city of Raleigh

Event O = Person is over 50 years old

The statement says, 'given that the person lives in Raleigh' which means that event R has already occurred and we need to find the probability of event O (the randomly chosen person is over 50 years old).

Hence, this statement can be given in conditional probability notation as

P(O|R)

The produce manager at a market orders 10 lb of tomatoes, 20 lb of zucchini, and 40 lb of onions from a local farmer one week.

rewona [7]

Answer:

(A) $A=\left[\begin{array}{ccc}10&20&40\end{array}\right]$

(B) $B=\left[\begin{array}{ccc}11&22&44\end{array}\right]$

Step-by-step explanation:

The manager ordered 10 lb of tomatoes, 20 lb of zucchini, and 40 lb of onions from a local farmer one week.

(A)

Matrix A represents the amount of each item ordered. It is 1 × 3 matrix.

Then matrix A is:

$A=\left[\begin{array}{ccc}10&20&40\end{array}\right]$

(B)

Next week the manager increases the order of all the products by 10%.

Then the amount of new orders are:

Tomatoes $=10\times [1+\frac{10}{100}]=10\times1.10=11$

Zucchini $=20\times [1+\frac{10}{100}]=20\times1.10=22$

Onions $=40\times [1+\frac{10}{100}]=40\times1.10=44$

Th matrix B represents the amount of each order for the next week. Then matrix B is:

$B=\left[\begin{array}{ccc}11&22&44\end{array}\right]$

(C)

Add the two matrix A and B as follows:

$A+B=\left[\begin{array}{ccc}10&20&40\end{array}\right]+\left[\begin{array}{ccc}11&22&44\end{array}\right]\\=\left[\begin{array}{ccc}(10+11)&(20+22)&(40+44)\end{array}\right]\\=\left[\begin{array}{ccc}21&42&84\end{array}\right]$

The entries of the matrix (A + B) represent the amount of tomatoes, zucchini and onions ordered for two weeks.

Help please!!!!!!!!!

REY [17]

Since all triangle's angle's values add up 180 degrees, this means we have to make sure to angles add up to 180.

A. 75 + 35 = 110. 180 - 110 = 70 degrees.

B. This triangle is isosceles meaning 2 of its sides is the same length. In this case, the two sides add up to 140 (meaning they are both 70 degrees). 180 - 140 = 40 degrees.

C. I sadly don't know how to solve it.

D. This is another isosceles triangle. 180 - 36 = 144.
