In a certain chemical, the ratio of zinc to copper is 4 to 15 . A jar of the chemical contains 480 grams of copper. How many grams of zinc does it contain?
The grams of zinc the jar of chemical contain is 128 grams
How to find the number grams of zinc ?In a certain chemical, the ratio of zinc to copper is 4 to 15 .
Therefore, a jar of the chemical contains 480 grams of copper.
The grams of zinc in the jar as follows:
Hence,
ratio of zinc to copper = 4 : 15
Therefore,
let
x = total grams in jar
Hence,
480 = 15 / 19 x
15x = 480 × 19
15x = 9120
x = 9120 / 15
x = 608
Therefore,
amount of zinc = 4 / 19 × 608
amount of zinc = 2432 / 19
amount of zinc = 128 grams

Step-by-step explanation:
The Demir family has a monthly budget of $5,500. Mrs. Demir works fulltime and takes home $4,000 each month. Mr. Demir works part-time and brings home earns $16 per hour. How many hours per month must Mr. Demir work at his part-time job to make sure that he and Mrs. Demir have met their monthly budget?
Answer:
93.75 hours
Step-by-step explanation:
The Demir family has a monthly budget of $5,500. Mrs. Demir works fulltime and takes home $4,000 each month.
Hence, the amount of money Mr Demir is meant to bring at the end of the month is :
Monthly budget - Amount of money that Mrs Demir takes home
= $5,500 - $4,000
= $1,500
From the question, we are told that:
Mr. Demir works part-time and brings home earns $16 per hour. How many hours per month must Mr. Demir work at his part-time job to make sure that he and Mrs. Demir have met their monthly budget?
This is calculated as:
$16 = 1 hour
$1,500 = x
Cross Multiply
16 × x = 1500 × 1
x = 1500 /16
x = 93.75 hours
Therefore, Mr Demir must work for 93.75 hours in a month at his part time job.

Answer: x° is 50°
Step-by-step explanation: The sum of the exterior angles of a polygon is 360.
Add the given exterior angles:
35+50+20+125=230
to find the missing exterior angle, supplementary to x°,
Subtract 360 - 230 = 130
The Sum of Supplementary angles is 180°
x° + 130° = 180°
x = 50

2x + y = 8
Answer: {y,x} = {4,2} ) ) ) )4
Step-by-step explanation: y
[2] y = -2x + 8
// Plug this in for variable y in equation [1]
[1] (-2x+8) - x = 2
[1] - 3x = -6
// Solve equation [1] for the variable x
[1] 3x = 6
[1] x = 2
// By now we know this much :
y = -2x+8
x = 2
// Use the x value to solve for y
y = -2(2)+8 = 4
Solution :
{y,x} = {4,2}

Step-by-step explanation:
When the sum of a number, n, and 6 is divided by 4 the
result is equal to 5. Set up and solve an equation to find
the value of n.
Answer:
n = 14
Step-by-step explanation:
(n + 6)4 = 5
1. multiply by 4
n + 6 = 20
2. substract 6
n = 14
The required value of n is 14 in the given sum.
What is algebra?Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.
We have been given that the sum of a number, n, and 6 is divided by 4 the result is equal to 5.
According to the given question, we can write the algebraic form would be as:
⇒ (n + 6)/4 = 5
Apply the cross-multiplication operation,
⇒ (n + 6) = 5 × 4
Apply the multiplication operation,
⇒ (n + 6) = 20
⇒ n = 20 - 6
Apply the subtraction operation,
⇒ n = 14
Therefore, the required value of n is 14.

Solve the equation 6x +2y = 10 for y in terms of x gives what function?
y = -6x +10
y = -3x +5
y = 2x
y = 3x + 5
Answer:
y = - 3x + 5
Step-by-step explanation:
Given
6x + 2y = 10 ( subtract 6x from both sides )
2y = - 6x + 10 ( divide all terms by 2 )
y = - 3x + 5
The correct equation for y in terms of x would be, y = - 3x + 5
Hence, option 2 is true.
Used the concept of an equation that states that,
An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.
Given that the expression is,
6x + 2y = 10
Now, simplify the equation for y in terms of x as,
6x + 2y = 10
Subtract both sides by 6x,
2y = - 6x + 10
Divide both sides by 2,
y = - 3x + 5
So, The correct equation would be, y = - 3x + 5
Thus, option 2 is true.

Answer: 21 cupcakes
Step-by-step explanation: x is the number of cupcakes. since she baked 45 cupcakes on tuesday, which is 3 more than 2x the number of cupcakes on monday, we would write 45=2x+3. First, subtract the 3 from both sides of the equation. This will give you 42=2x. Then divide both sides by 2. This will give you 21=x. So, the answer is 21

Two ferries just departed from their docks at the same time. Ferry A departs every 1.2 hours. Ferry B departs every 1.8 hours. How long will it be until both ferries depart from their docks at the same time again?
Answer: It will take 36 minutes(0.6 hour) until both ferries depart from their docks at the same time again.
Step-by-step explanation:
Given : Ferry A departs every 1.2 hours.
Ferry B departs every 1.8 hours.
To find : Time taken by both ferries until they depart from their docks at the same time again.
= LCM (1.2, 1.8) hours [LCM= Least common multiple]
= LCM (1.2(60 minutes), 1.8(60 minutes)) [Since 1 hour = 60 minutes]
= LCM (72 minutes, 108 minutes)
72 = 2 x 2 x 2 x 3 x 3 , 108 = 3 x 3 x 3 x 2 x 2
LCM (72,108) =2 x 2 x 3 x 3 =36
So, it will take 36 minutes until both ferries depart from their docks at the same time again.
In hour = [tex]\dfrac{36}{60}\text{ hour}=0.6\text{ hour}[/tex]

Step-by-step explanation:
6.25% of $10,624 is $664, so that is the amount of interest every year.
$664 times 4 is $2656, so after 4 years $2656 will have been paid.
