From 1980 to 1990, Lior’s weight increased by 25%. If his weight was k kilograms in 1990, what was it in 1980?

Answers

An increase of 25% is represented by the multiplier 1.00 + 0.25, or 1.25.
Then Lior's 1980 weight, mult. by 1.25, results in his 1990 weight, or k kg.

Let his 1980 weight be w. Then 1.25w = k. Divide both sides by 1.25 to obtain w, Lior's 1980 weight:

1.25 w = k
--------- ------- = (4/5)k, or 4k/5 (answer)
1.25 1.25

Ththe weight of Lior in 1990 in terms of k is [tex]\frac{4}{5} k[/tex]

Let the weight of Lior in 1980 be "w"

If Lior's weight increased by 25%, his new weight was "k". This can be expressed as:

w + (25% of w) = k

w + (0.255w) = k

w + 0.15w = k

1.25w = k

Divide both sides by 1.25

[tex]\frac{1.25w}{1.25} =\frac{k}{1.25} \\w=\frac{k}{1.25} \\w=\frac{100k}{125} \\w=\frac{4}{5}k[/tex]

This shows that the weight of Lior in 1990 in terms of k is [tex]\frac{4}{5} k[/tex]

collection of dimes and quarters has a total of $19.55. If there are three times as many quarters as dimes, find the number of each?

Answers

Use one equation for the number of coins and another equation for the value of the coins.

Let d = number of dimes.
Let q = number of quarters.

Number of coins:
q = 3d

Value of the coins:
A dime is worth $0.1
A quarter is worth $0.25

0.1d + 0.25q = 19.55

Now solve the two equations as a system of equations.

q = 3d
0.1d + 0.25q = 19.55

Since the first equation is already solved for q, replace q with 3d in the second equation.

0.1d + 0.25(3d) = 19.55

0.1d + 0.75d = 19.55

0.85d = 19.55

d = 23

q = 3d = 3(23) = 69

There are 23 dimes and 69 quarters.

Check:
23 dimes are worth 23 * $0.1 = $2.30
69 quarters are worth 69 * $0.25 = $17.25
The total value is $2.30 + $17.25 = $19.55
Also 69 is 3 times 23, so the number of quarters is indeed three times the number of dimes.
Our answer is correct.

A deep-sea diver is in search of coral reefs. He finds a beautiful one at an elevation of -120 4/7 feet. While taking pictures of the reef, he catches sight of a manta ray. He swims up 25 3/7 feet to check it out. What is the diver's new elevation?

Answers

To start, create an expression to represent the situation: -120 4/7 + 25 3/7
Since the diver goes up 25 3/7 from their current spot, you would add 25 3/7 to -120 4/7.
This expression would then simplify to -95 1/7 (first, you combine -120 and 25 since they have a fraction that share the same denominator, and then you combine -4/7 and 3/7). The diver's new elevation would be -95 1/7.

The position of the diver's new elevation will be negative 666 / 7.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A remote ocean jumper is looking for coral reefs. He tracks down a wonderful one at a rise of - 120 ⁴/₇ feet. While taking photos of the reef, he sees a manta beam. He swims up 25 ³/₇ feet to look at it.

Convert the mixed fraction number into a fraction number. Then we have

- 120 ⁴/₇ = - 844 / 7

25 ³/₇ = 178 / 7

The position of the diver's new elevation will be given as,

⇒ - 844 / 7 + 178 / 7

⇒ (- 844 + 178) / 7

⇒ - 666/7

The position of the diver's new elevation will be negative 666 / 7.

While going on a field trip, a busload of 54 students will have to be split up into three groups. two thirds will go to lunch first, and one third will go visit the exhibits. how many will go to lunch first?

Answers

*Given
Total number of students - 54
Fraction of students going to lunch first - 2/3
Fraction of students going to the exhibit first - 1/3

*Solution
1. Since the students are grouped into 3, the total number of students must be divided into 3 to determine the number of students in each of the 3 groups.

54/3 = 18

Thus, there are 18 students per group.

2. Two-thirds (2/3) of the total number of students will go to lunch first. Since the total number of students have already been divided into 3 groups, this simply means that 2 of the 3 groups will go to lunch first. Since each group has 18 students, 2 groups would have,

18*2 = 36

Thus, 36 students will go to lunch first.

Is this a direct variation? 4y=x

Answers

Final answer:

The equation 4y = x represents a direct variation. This type of relationship between variables implies that the ratio between x and y is constant. In this specific example, the constant of variation is 0.25.

Explanation:

Yes, the given equation 4y = x is a representation of direct variation. Direct variation in mathematics refers to a situation where the ratio of two variables is constant. In a direct variation equation the form is y = kx, where k is the constant of variation. Here, you can rewrite 4y = x as y = x/4 or y = 0.25x, so the constant of variation is 0.25. It's important to note that a direct variation has no y-intercept, it always passes through the origin (0,0) which is the case in this equation.

During a certain week, a post office sold Rs.280 worth of 14-paisas stamps. How many of these stamps did they sell?

Answers

So basically ...

You convert the rupees in paisas. One rupee is equal to one hundred paisas, so ...

280 × 100 = 28,000

And then we divide,

28,000 ÷ 14 = 2000

The post office sold 2000 stamps!

Hope this helped! :)

The post office sold 2000.

To find out how many 14-paisa stamps the post office sold to make Rs.280, we need to follow a step-by-step solution.

Convert the total amount from rupees to paisas:Since the stamp's value is given in paisas.There are 100 paisas in 1 rupee.Rs.280 = 280 x 100 = 28000 paisas.The value of one stamp is 14 paisas.To find the number of stamps sold, we divide the total amount in paisas by the value of one stamp:

28000 paisas ÷ 14 paisas per stamp = 2000 stamps.

A really bad carton of 18 eggs contains 9 spoiled eggs. an unsuspecting chef picks 6 eggs at random for his "mega-omelet surprise." find the probability that the number of unspoiled eggs among the 6 selected is

Answers

Final answer:

Explanation:

To find the probability that the number of unspoiled eggs among the 6 selected is X, we can use the hypergeometric probability formula. This formula is used when the sample drawn is without replacement from a finite population. In this case, we have 18 total eggs in the carton, with 9 spoiled eggs. So the probability that X unspoiled eggs are selected out of the 6 can be calculated as:

P(X) = (C(X,6) * C(9,6)) / C(18,6)

Where C(n,r) represents the combination of n things taken r at a time.

A single microvillus is a rod-like structure that is 1.0 μm in height. it has a hemispherical top approximately 0.1 μm in diameter. calculate the surface area of the cylinder that forms the "sides" of the microvillus rod. use 3.14 for π.

Answers

Final answer:

The surface area of the cylinder forming the sides of a microvillus rod with a diameter of 0.1 µm and a height of 1.0 µm is 0.314 µm².

Explanation:

To calculate the surface area of the cylinder that forms the "sides" of the microvillus rod, we will use the formula for the surface area of a cylinder without the top or bottom, which is circumference multiplied by height

(A = 2πrh).

Since the diameter (d) of the microvillus is given as 0.1 µm, we first find the radius (r) by dividing the diameter by 2.

Therefore, r = 0.1 µm / 2 = 0.05 µm.

The height (h) is given as 1.0 µm.

Inserting these values into our formula, we get:

A = 2 × 3.14 × 0.05 µm × 1.0 µm = 0.314 µm².

Hence, the surface area of the sides of the microvillus rod is 0.314 µm².

A farmer harvested 35 acres of corn and 20 acres of beans. Animals ate 1/8 of the corn he originally planted. how many acres of corn did the farmer plant?

Answers

now..... we're assuming here, that the farmer planted "more than 35 acres" of corn, so, he planted some amount of corn, but he only harvested a fraction of it, which is 35 acres, and we're assuming he gave those 35 acres of harvested corn to the livestock, so the animals ate 1/8 of the corn he planted.

That means, if the animals ate 1/8 of the corn, and the farmer gave the animals the whole of the harvested corn, then we can say that the 35 acres is just 1/8 of what he planted.

To solve this problem, we need to find out how many full boxes of 5 widgets we can make from 26 widgets and how many single widgets we will have left. Whole number quantities, such as the number of widgets and boxes, are important here. First, we divide 26 by 5 to find out the number of full boxes.
