An element with mass 590 grams decays by 19.5% per minute. How much of the
element is remaining after 15 minutes, to the nearest 10th of a gram?

Answers

22.8 gms

Step-by-step explanation:

Step 1:

Given,

Mass of the element = 590 gms

Percentage decay per minute = 19.5%

Step 2 :

Fraction of the element remaining at the end of 1 minute = 1 - 0.195 = 0.805

Hence the fraction of element remaining after 15 minutes = [tex]0.805^{15}[/tex] = 0.03863

So the mass of the element remaining after 15 minutes = 0.03863 * 590 = 22.8 rounded off to the nearest 10th of a gram

mass of the element remaining after 15 minutes = 22.8 gms

siw is a fourth as old as mother, and Mona is a fifth as old as mother. Mother is 22 years older than the two girls together. How old are they?

Answers

Answer:

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

Step-by-step explanation:

Let

x ----> Siw's age

y ---> Mona's age

z ---> Mother's age

we know that

Siw is a fourth as old as mother

[tex]x=\frac{1}{4}z[/tex] ----> equation A

Mona is a fifth as old as mother

[tex]y=\frac{1}{5}z[/tex] ----> equation B

Mother is 22 years older than the two girls together.

[tex]z=x+y+22[/tex] ----> equation C

substitute equation A and equation B in equation C

[tex]z=\frac{1}{4}z+\frac{1}{5}z+22[/tex]

solve for z

Multiply by 20 both sides to remove the fraction

[tex]20z=5z+4z+440[/tex]

[tex]20z-9z=440\\11z=440\\z=40\ years[/tex]

Find the value of x

[tex]x=\frac{1}{4}(40)=10\ years[/tex]

Find the value of y

[tex]y=\frac{1}{5}(40)=8\ years[/tex]

therefore

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

Answers

Answer:

B) 6 tan(35°)

Step-by-step explanation:

from the right angle tan° = opposite / adjacent

therefore tan (35°) = (x) / 6

by multiplying 6 to both sides

tan (35°) * 6 = (x) / 6 * 6

We substitute into the formula for T,

The cost price of the 80 articles €200

The selling price is 3.5×80=€280

The profit =€280-€200=€80

The percentage profit is now

[tex] = \frac{80}{200} \times 100\%[/tex]

[tex] = 0.4 \times 100\%[/tex]

[tex]40\%[/tex]

The percentage profit is 40%

Question 3)

We equate and solve for x.

[tex] \frac{85}{100} x= 32.89[/tex]

[tex]0.85x = 32.89[/tex]

[tex]x = \frac{32.89}{0.85} [/tex]

[tex]x = 38.69[/tex]

The original price is €38.69

there are 250 toothpicks in a regular size box. a jumbo size box is made by tripling the length,width, and height of the regular box. how many toothpicks will the jumbo box hold

Answers

Answer:6750

Step-by-step explanation:

Final answer:

The jumbo-sized box, created by tripling each dimension of a regular-sized box that holds 250 toothpicks, will have a volume 27 times greater. Therefore, it will hold 250 × 27 = 6,750 toothpicks.

Explanation:

The question is asking how many toothpicks a jumbo-sized box can hold if it is created by tripling the length, width, and height of a regular-sized box that holds 250 toothpicks. To find the answer, we need to consider the volume of the boxes because the toothpicks are arranged in three-dimensional space.

The volume of a box is calculated by multiplying its length by its width by its height. If we triple each of these dimensions for the jumbo box, the new volume will be 27 times the volume of the original box (since 3 × 3 × 3 = 27). Therefore, if the original box holds 250 toothpicks, the jumbo box will hold 250 × 27 toothpicks.

To find the total number of toothpicks:

Multiply the number of toothpicks in the original box (250) by 27.

Calculate 250 × 27 to get 6,750 toothpicks.

Thus, the jumbo-sized box would be able to hold 6,750 toothpicks.

simplify xz^3*4x^4z^5

Answers

Final answer:

To simplify the expression xz^3*4x^4z^5, the exponents of the like bases are added together resulting in 4x^5z^8. This application of exponent rules shows that the exponents on the same base are summed during multiplication.

Explanation:

To simplify the expression xz^3*4x^4z^5, we need to apply the rules of exponents. Specifically, when multiplying two expressions with the same base, we add their exponents.

Beginning with the variable x, we have an implied exponent of 1 on the standalone x, so when combined with x^4, we get x^(1+4), which simplifies to x^5.

Next, we apply the same rule to the variable z.

The expression z^3 multiplied by z^5 becomes z^(3+5), which simplifies to z^8. Finally, we multiply these results by the constant 4 to get our simplified expression:

4x^5z^8.

As an example to clarify this process, imagine a simpler case like (5^3)^4.

This could be written out as multiple fives multiplied by each other, illustrating that the exponents are indeed added together when multiplying like bases, just as we did with x and z in our original expression.

Javier moves backward so that his horizontal distance from the tree is
greater. Will the distance from his eyes to the top of the tree also be
greater? Explain.

Answers

Answer:

Yes it will be greater, he is moving back 3 feet so what you are doing is taking the leg (a2) and multiplying it by 3. Once you do, you see triangle 1 has double and so did triangle 2. Triangle 1 was originally 5.6 (rounded to 6) than went up to 26.1. Triangle 2 was originally 24 and went up to 74.7 (or 75)

Step-by-step explanation:

Triangle 1 (when multiply by 3)

a2+b2=c2

7(square to 2)+b2=27(square to 2)

49+b2=729

-49 -49

--------------------

b2=680

(square root it)

b=26.1 Rounded to nearest tenth

Triangle 2:

a2+b2=c2

7(square to 2)+b2=75(square to 2)

49+b2=5625

-49 -49

-------------------

b2=5576

(square root it)

b=74.7 (or 75 rounded to nearest tenth)

Hope this helps anyone who needs it :)

Yes, the distance from his eyes to the top of the tree will also be greater.

What is function?

A function is a relation between a dependent and independent variable.

Mathematically, we can write → y = f(x) = ax + b.

Given is that Javier moves backward so that his horizontal distance from the tree is greater.

Before moving backward, the distance from Javier's eyes to the top of the tree can be written as -

cosФ = b/h

h = b/cosФ

Now, we can see that -

h [tex]\alpha[/tex] b

As base increases, the hypotenuse length or the distance from Javier's eyes to the top of the tree will increase.

Therefore, yes, the distance from his eyes to the top of the tree will also be greater.
