In a certain chemical, the ratio of zinc to copper is 4 to 11. A jar of the Chemical contains 495 grams of copper. How many grams of zinc of does it contain

Answers

Answer 1

The answer to our inquiry is that 180 grams of zinc contain a particular compound.

How is a ratio calculated?

Ratios contrast two figures by ordinarily dividing them. A/B would be your formula if you were going to compare another data item (A) to this other data point (B).

The zinc to copper ratio in a particular compound is 4: 11.

Copper weighs 495 grammes in the chemical.

How much zinc does it chemically contain in grammes.

Assume that y is the scalar multiple of zinc and copper.

as stated

The proportion of zinc over copper in a certain compound is 4 to 11.

Copper weighs 495 g in the chemical.

Equation is than

11y = 495

11y = 495

y = 495/11

y = 45

Zinc in a particular chemical = 4y

= 4x45

= 180 grams

Therefore 180 grams of zinc contain in a certain chemical .

The length of one edge of the cube is 8 cm and the radius of the sphere is 9 cm.

What is the cube root?

The cube root of a number is a value that when multiplied by itself thrice or three times produces the original value. For example, the cube root of 27, denoted as 3√27, is 3, because when we multiply 3 by itself three times we get 3 x 3 x 3 = 27 = 33.

The surface area of a cube is given by the formula:

A = 6 * a^2

where A is the surface area and a is the length of one edge of the cube.

So, in this case:

384 = 6 * a²

Dividing both sides by 6:

64 = a²

Taking the square root of both sides:

a = 8 cm

So the length of one edge of the cube is 8 cm.

The formula for the volume of a sphere is:

V = (4/3) * π * r³

where V is the volume, π is Pi (approximately equal to 3.14), and r is the radius of the sphere.

So, in this case:

729 = (4/3) * π * r³

Dividing both sides by (4/3) * π:

729 / (4/3) * π = r³

Taking the cube root of both sides:

r = pow(729 / (4/3) * π, 1/3) = 9 cm

So the radius of the sphere is 9 cm.

The cube root of 729 is 9.

Hence, the length of one edge of the cube is 8 cm and the radius of the sphere is 9 cm.

If y varies directly with x and y= – 93 when x= – 3, find y when x=2.

A wheel of cheese has a radius of 7 inches and a height of 3 inches. What is the approximate surface area of this wheel of cheese? Use 3.14 for pi.

Answers

A wheel of cheese has a radius of 7 inches and a height of 3 inches

The approximate surface area of this wheel of cheese is 458.4 square inches.

To get the surface area of a cylinder,  we have to calculate the area of the lateral surface and add the areas of the two circular end faces.

The lateral surface area of a cylinder is calculated as 2 * pi * r * h, where r is the radius and h is the height.

So the lateral surface area in this scenario would be: 2 * 3.14 * 7 * 3 = 150.52 square inches.

The area of the two end faces must then be calculated. we know, Pi * r^2, where r is the radius, gives the area of a circle.

So the area of each end face in this situation would be 3.14 * 7^2 = 153.94 square inches.

Total surface area= lateral surface area + end face area

=150.52 + 153.94 + 153.94 = 458.4 square inches (approximately)

Greetings!!!

Firstly, remember the sin trigonometric equation

Assuming the image as this question and solve

If you have any questions or unclear ideas tag on comments

Hope it helps!!!

The value of the indicated trigonometric ratio sin( α ) is (16√281 )/281.

What is the value of sin(α)?

The figure in the image is a right triangle.

Angle ∠A = αAdjacent to angle ∠A = 5Opposite to angle ∠A = 16Hypotenuse = √281

To find sin(α), we use trigonometric ratio.

Sine = Opposite / Hypotenuse

Plug in the values

sin( α ) = 16/√281

To simplify further, we rationalize the denominator

Multiply both the numerator and denominator by √281

sin( α ) = (16 × √281 ) /(√281 × √281 )

sin( α ) = (16 × √281 ) / 281

sin( α ) = (16√281 )/281

Therefore, the value of sin( α ) is (16√281 )/281.

0,4277 rounded to 2 decimal places?

0.43

Step-by-step explanation:

Rounding to 2 decimal places means keeping only 2 digits after the decimal point and adjusting the third digit, based on the rules of rounding. In this case, the number 0.4277 would be rounded to 0.43. This is because the third digit after the decimal point (7) is 5 or greater, so we round up the second digit (2) to 3. This gives us the rounded number 0.43, which has only 2 decimal places.

. A motocross company offers a loan to buy an ATV
for $4,000. What is the monthly payment?
Loan Offer
9.3% Simple Interest
Equal monthly payments for 6 years.
C

Answers

The monthly payment is  $86.55. The result is obtained by using the formula for simple interest.

How to count the simple interest?

The simple interest of an amount of money can be counted by the following formula.

I = P × r × t

Where

I = simple interestP = principal amount (initial balance)r = simple interest rate (usually per year)t = time period

A motocross company offers a loan to buy an ATV for $4,000. Loan Offer 9.3% Simple Interest.

If it is for 6 years, find the monthly payment!

We have

r = 9.3%P = $4,000t = 6 years

It is not mentioned that the simple interest apply per year or per month. We assume the simple interest is per year. It will be

I = P × r × t

I = $4,000 × 9.3% × 6

I = $2,232

The total money to be paid will be

A = P + I

A = $4,000 + $2,232

A = $6,232

The monthly payment is

MP = A/t

MP = $6,232/(6 × 12)

MP = $6,232/72

MP = $86.55

Hence, the person who borrows for $4,000 to buy an ATV should pay $86.55 each month for 6 years.

Find each exact value if 0
Sin (x - y) if cos x = 8/17 and cos y = 3/5

Answers

Answer:  13/85

Work Shown:

If cos(x) = 8/17, then sin(x) = 15/17. Use the identity [tex]\sin^2(\text{x}) + \cos^2(\text{x}) = 1[/tex] to determine this.

If cos(y) = 3/5, then sin(y) = 4/5 using that same identity.

So,

sin(x-y) = sin(x)cos(y) - cos(x)sin(y)

sin(x-y) = (15/17)*(3/5) - (8/17)*(4/5)

sin(x-y) = 45/85 - 32/85

sin(x-y) = (45 - 32)/85

sin(x-y) = 13/85

Jose has scored 570 points on his math tests so far this semester. To get an A for the semester, he must score at least 660 points. Write and solve an inequality to find the minimum number of points he must score on the remaining tests, n, in order to get an A.

Answers

Answer:

Step-by-step explanation:

Let's start by defining a variable to represent the minimum number of points that Jose must score on the remaining tests:

n = minimum number of points Jose must score on the remaining tests

To get an A for the semester, Jose must score at least 660 points. We know that he has already scored 570 points, so the total number of points he needs to score is:

660 - 570 = 90

Therefore, we can write the following inequality to find the minimum number of points Jose must score on the remaining tests:

n ≥ 90

This means that Jose must score at least 90 points on the remaining tests to get an A for the semester.

Which is the standard form of the equation with p=26, theta=3pi/4

Answers

The standard form of the equation for the given p value and theta is equal to -x + y = 26√2.

Standard form of the equation is :

x cosθ + y sinθ = p

Here p = 26 and theta 'θ' = 3π /4

Substitute the value in the standard form we get,

x cos (3π/4 ) + y sin( 3π /4 ) = 26

⇒ x cos ( π - π/4 ) + y sin ( π - π/4 ) = 26

⇒ - x cosπ/4 + y sinπ/4 = 26

Substitute the value of cosπ/4 and sinπ/4 is equal to 1/√2 we get,

⇒ -x /√2 + y / √2 = 26

⇒ -x + y = 26√2

Therefore, the standard form of the equation is equal to -x + y = 26√2.

Answers

Answer:

(D)105 ft

Step-by-step explanation:

In a triangle, the sides have a ratio of 3:7:10. If the perimeter is 210 feet, what is the length of the longest side in feet? (A) * 10.5 (B) 31.5 (C) (D) 105​

we divide the perimeter by the sum of the ratios and multiply by the largest ratio and we will have the longest side.

[210 : (3 + 7 + 10)] x 10 = 105 ft (your answer)

Step-by-step explanation:

the ratio tells us into how many units the total amount is split and then distributed among the different parts or members of the ratio.

3:7:10 means there are 3+7+10 = 20 units of length.

210 ft is the total of all lengths.

this is now split into these 20 units.

that means one unit of length for the ratio is

210/20 = 10.5 ft

the longest side is clearly the one with 10 units in the ratio.

so, it has

10×10.5 = 105 ft
