19. What is the angle of elevation, tothe nearest tenth of a degree, tothe top of a 45-foot building from85 feet away?
Answers
Given data:
The given height of the building is H=45 ft.
The given distance is D=85 ft.
The expression for the angle of elevation is,
\(\begin{gathered} \tan \theta=\frac{H}{D} \\ \theta=\tan ^{-1}(\frac{45}{85}) \\ =27.9^{\circ} \end{gathered}\)Thus, the angle of elevation is 27.9 degrees.

Identify the correct graph of the system of equations.
3x + y = 12
x + 4y = 4
Answers
Let's solve the system of equations:
1. 3x + y = 12
2. x + 4y = 4
We can solve this system of equations using various methods such as substitution or elimination. Let's use the elimination method here:
Multiply equation 1 by 4 and equation 2 by 1 to eliminate the y term:
1. 12x + 4y = 48
2. x + 4y = 4
Now, subtract equation 2 from equation 1:
12x + 4y - (x + 4y) = 48 - 4
Simplifying:
11x = 44
Divide both sides by 11:
x = 4
Substitute the value of x into equation 2 to solve for y:
4 + 4y = 4
4y = 4 - 4
4y = 0
y = 0
Therefore, the solution to the system of equations is x = 4 and y = 0.
The correct graph of this system of equations would be two lines intersecting at the point (4, 0) on the coordinate plane.

Peter had 208 Canadian stamps and 186 Mexican stamps for sale. The stamps were mixed up and sold in packets of 6. How many packets of stamps were there? How many stamps were left over?
Answers
Answer:
65 packets and 4 stamps
Step-by-step explanation:
The first thing we see is that the stamps are mixed... which means they must be added.
208 + 186 = 394 stamps total
Now we see that each packet has 6 stamps. So we divide the number of stamps in total by 6.
394/6= 65.66667
Now we see from that number that the stamps can't quite make 66 packets, so there are 65 packets.
Now we find the number of stamps left over by multiplying the number of packets by 6.
65 x 6= 390
Now we take the total number of stamps minus the number of stamps in packets.
394 - 390 = 4
Therefore, there are four stamps left over.

What is unitary method ?The unit method is a strategy for solving issues that entails first figuring out the value of just one unit, and subsequently multiplying that number to figure out the needed value. Simply stated, the unit method is used to determine only one value via a multiple that is supplied. For example, 40 pens might run you 400 rupees, which is equal to the expense of one pen. This procedure might follow a conventional procedure. a distinct nation. anything with a distinct character. Its adjoint and equivalent are identical in terms of mathematics, algebra, linear equations, mathematical analysis, or math of matrices or operators.
Since the goods Waegelein shipped to another business on consignment are not Waegelein's property and are only being kept on hand for possible sale, they should not be included in the inventory count.
Since Waegelein receives title to the goods upon delivery at the destination and is in charge of them going forward, goods in transit from a supplier shipped FOB destination should be included in the inventory taking.

Step-by-step explanation:
To find the missing number in the given sequence, let's analyze the pattern:
2, 4, 3, 6, 6, 3, 8, 9, 7, 9, 8, ???
Looking at the sequence, we can identify a few patterns:
The sequence alternates between increasing and decreasing numbers.
The first two numbers, 2 and 4, are increasing.
The next two numbers, 4 and 3, are decreasing.
The following two numbers, 3 and 6, are increasing.
The subsequent two numbers, 6 and 3, are decreasing.
The next two numbers, 3 and 8, are increasing.
The subsequent two numbers, 8 and 9, are increasing.
Based on these observations, it appears that the sequence is following a pattern where it alternates between increasing and decreasing numbers, but the specific values being added or subtracted are not consistent.
Now let's determine the missing number:
From the pattern, the next two numbers should be decreasing. Following the pattern of alternating between increasing and decreasing numbers, the missing number after the last given number (8) should be less than 9.
Let's assume the missing number is x:
8 - x
Since the previous decreasing sequence was 6 - 3, we can assume that x is 1 less than the previous number (3):
8 - (3 - 1) = 8 - 2 = 6
Therefore, the missing number in the sequence is 6.
The complete sequence is:
2, 4, 3, 6, 6, 3, 8, 9, 7, 9, 8, 6

7. Phozia has three pieces of rope with lengths of 160 cm, 192 cm and
240 cm respectively. She wishes to cut all three pieces of rope into
shorter pieces of equal length so that there is no left over rope.
(a) What is the largest possible length of each of the shorter pieces of
rope?
(b) How many shorter pieces of rope can she get altogether?
Answers
Answer:
a) 16 cm, b) 37 pieces
Step-by-step explanation:
Part a
Finding the largest divisor of 160, 192 and 240
160 divisors: 1, 2, 4, 5, 8, 10, 16, 32, 40, 80 and 160.
// You can alternatively find them by factor pairs, which are (1, 160), (2, 80), (4, 40), (5, 32), (8, 20) & (10, 16). This way is much more faster. Also, you can simply search them in metanumbers.com
192 divisors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96 and 192
240 divisors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120 and 240
The largest divider that they all have in common is 16.
So 16 cm is the largest possible length of each of the shorter pieces of
rope
Part b
Now we have to count how many 16 cm pieces of rope can we get from the large rope pieces, which lengths are 160 cm, 192 cm and 240 cm
160/16 + 192/16 + 240/16 = 10 + 12 + 15 = 37
The answer is 37 pieces

Damien needs to order more pill containers for the pharmacy. Currently, there are 156 8-dram bottles, 78 20-dram bottles, and 132 30-dram bottles. All the bottles come in cases of 140 bottles. The pharmacist wants all stocks to be replenished so that there are at least 400 of each bottle type. How many cases of each bottle type does Damien need to order
Answers
Answer:
for 8 gram bottle = 2 cases
for 20 gram bottle = 3 cases
for 30 gram bottles = 2 cases
Step-by-step explanation:
Determine how many cases of each bottle type Damien needs to order
i) For 8-gram bottles
available bottles = 156
required amount ≥ 400
extra bottles to be ordered = 400 - 156 = 244 bottles
since case contains 140 bottles , the number of cases to be ordered
= 244 / 140 = 1.74 cases ≈ 2 cases
ii) for 20 gram bottles
available bottles = 78
required amount ≥ 400
Extra bottles to be ordered = 400 - 78 = 322 bottles
therefore the number of cases = 322 / 140 = 2.3 cases ≈ 3 cases
iii) For 30 gram bottles
available bottles = 132
required amount ≥ 400
Extra bottles to be ordered = 400 - 132 = 268
therefore the number of cases = 268 / 140 = 1.9 ≈ 2 cases
A four-ounce serving of Campbell's Pork & Beans contains 5 grams of protein and 21 grams of carbohydrates A typical slice of "lite" rye bread contains 4 grams of protein and 12 grams of carbohydrates.
(a) I am planning a meal of "beans-on-toast" and I want it to supply 20 grams of protein and 80 grams of carbohy- drates. How should I prepare my meal?
(b)If I require A grams of protein and B grams of carbohy- drates, give a formula that tells me how many slices of bread and how many servings of Pork & Beans to use.
Answers
(a) To meet the desired 20g protein and 80g carbohydrate intake, prepare 4 servings of Pork & Beans and combine with 15 slices of "lite" rye bread.
(b) Bread: A/4 slices, Beans: B/21 - (A/4) * (12/21) servings.
(a) To prepare a meal of "beans-on-toast" that supplies 20 grams of protein and 80 grams of carbohydrates, you can use the following combination:
- Servings of Campbell's Pork & Beans: 4 servings.
- Slices of "lite" rye bread: 15 slices.
By using 4 servings of Campbell's Pork & Beans, you will obtain a total of 20 grams of protein (5 grams per serving) and 84 grams of carbohydrates (21 grams per serving).
Combining this with 15 slices of "lite" rye bread will contribute an additional 60 grams of carbohydrates (12 grams per slice) and 4 grams of protein (4 grams per slice). Thus, your meal will meet the desired nutritional requirements of 20 grams of protein and 80 grams of carbohydrates.
(b) The formula to determine the number of slices of bread and servings of Pork & Beans needed to meet specific protein and carbohydrate requirements is as follows:
- Number of slices of bread (Bread): A divided by 4.
- Number of servings of Pork & Beans (Beans): (B divided by 21) minus ((A divided by 4) multiplied by (12 divided by 21)).
Using this formula, you can calculate the appropriate quantities of bread and beans based on the desired protein (A) and carbohydrate (B) values.
