Answer:
13.5 kgs.
Step-by-step explanation:
Here we have to find conversion factor of lbs into kg.
For this we use the given information.
Given that the weight of a dog is 20 lbs and also 9 kg.
Hence we have conversion factor as
20 lbs = 9 kg
Or 1 lb =9/20 = 0.45 kg.
Using this, we find the 30 lb converted into kg.
For 1 lb, equivalent kg = 0.45
Hence for 30 lbs equivalent kg= 30(0.45) = 13.5 kg.
Mr. Sloan said that his car was worth $30,000 when he first purchased it however over the last three years it has decreased in value $5400 what integer represents the average decrease in value per year?
Answer:
Average decrease in car's value per year = 1800$
Explanation:
The worth of car bought by Mr. Solan = 30000$
Reduction of car's price = 5400$
Number of years considered for measuring reduction of car's price = 3 years.
Average of values = Total of the values/ Number of values.
Average reduction per year = Total reduction/ Number of years.
= 5400/3 = 1800$
So average decrease in car's value per year = 1800$
If f(x)= 6x+7, determine the value of f(-3)
To evaluate a function at a specific x value simply means to substitute that particular value in place of every occurrence of the variable x.
So, starting from [tex] f(x) = 6x+7 [/tex], we have
[tex] f(-3) = 6\cdot(-3)+7 = -18+7 = -11 [/tex]
Solve for r.
35r−21<−35r+19
70 r − 21 < 19
70r<40
r=4/7
Answer:
r< 4/7
Step-by-step explanation:
-12=-2v
whats the value of v
6 because -12/-2 would be positive 2
V=6
divide both sides by -2 to get variable v on one side
-12/-2=6
Write the word sentence as an equation. Then solve. The product of 15 and a number x is −75.
15x = -75 Divide both sides by 15.
Final answer: -5
hope that helps
Solving the product of 15 and a number x is −75 equals to: -5.
Let the number be x.To write the word sentence as an algebraic equation:
In this exercise, we are required to translate the word sentence into a mathematical (algebraic) expression and solve for the unknown variable (number):
The product of 15 and a number x:
[tex]15(x)[/tex]
Equating the above expression to -75, we have:
[tex]15x = -75[/tex]
Simplifying further, we have:
[tex]15x = -75\\\\x = \frac{-75}{15}[/tex]
x = -5
Therefore, the unknown number is -5.

find the x and y intercept of the graph of 2(y+0.5)=3.5x+2y
Final answer:
The x-intercept of the graph 2(y+0.5) = 3.5x + 2y is 2/7, and the y-intercept is 0.5.
Explanation:
To find the x and y intercepts of the graph of the equation 2(y+0.5) = 3.5x + 2y, we first simplify the equation. Start by distributing the 2 on the left side:
2y + 1 = 3.5x + 2y. Next, subtract 2y from both sides to get:
1 = 3.5x. Now, to find the x-intercept, set y to zero and solve for x:
x-intercept: y = 0
1 = 3.5x
x = 1 / 3.5
x = 2/7
To find the y-intercept, set x to zero and solve for y:
y-intercept: x = 0
1 = 2y
y = 1 / 2
y = 0.5
The x-intercept is 2/7, and the y-intercept is 0.5.
omar runs 12 miles in 104 minutes. how many miles does he run per minute?
Omar runs about 0.12 miles per minute.
To find this answer, you simply divide both 104 and 12, by 104. In doing so, you'll get 0.115... miles per 1 minute. Rounding up, you'll get 0.12 miles per minute.

The 2 points closest to the line is (4,12) and (20, 36)
The slope is the change in Y over the change in x:
Slope = (36-12) / (20-4)
Slope = 24 / 16
Slope = 1.5
So now you have y = 1.5x
To find the equation use the formula (y-y1) = m*(x-x1)
y-12 = 1.5(x-4)
Simplify the right side:
y-12 = 1.5x - 6
Add 12 to each side:
y = 1.5x +6

Given that the product of 22 integers is equal to 1, prove that their sum is not equal to 0.
1. If the product of these integers is to be 1, then all of them must be either 1 or -1.
2. Since the product is positive (+1), it must be that there are an *even* number of negative ones (-1), if any.
3. If the sum were 0 it would mean that the number of +1's must equal the number of -1's. So that means there would have to be exactly 22/2=11 of each.
4. But if there were 11 of each, that means the number of -1's would be *odd* and there's no way the product could be +1 (as stated in 2 above).
Hence, the sum is never 0, if the product of 22 integers is equal +1.
Fun problem.
We have a positive product, so no zero factors.
We have a positive product, so an even number of negative factors.
We have a product of 1, so all the integers must be either +1 or -1.
If we have 2n factors of -1 we have 22-2n factors of 1 so a sum of
[tex]s = (-1)2n + (1)(22-2n) = 22-4n[/tex]
For that to be zero we need
[tex]0 = 22-4n[/tex]
[tex]n = 22/4 = 11/2[/tex]
That's not an integer; we've shown there's no even number of -1s that will make the sum zero, and since there must be an even number of -1s, the sum cannot equal zero.

which equation has no solution?
a. 5m-6=5m+7-m
b. 3w+4-w=5w-2(w-2)
c. 7y+9=7y-6
d. 4z+8=-4z-2
The equation which has no solution is:
Option: C
c) [tex]7y+9=7y-6[/tex]
Step-by-step explanation:The equation is said to have a no solution if we get a false identity on solving the equation.
a)
[tex]5m-6=5m+7-m[/tex]
On combining the like terms in the right hand side of the equation we have:
[tex]5m-6=5m-m+7\\\\5m-6=4m+7\\\\5m-4m=7+6\\\\m=13[/tex]
Hence, we get a unique solution to the equation.
b)
[tex]3w+4-w=5w-2(2w-2)[/tex]
on using the distributive property in the right hand side of the equation we have:
[tex]3w+4-w=5w-2\times w-2\times (-2)\\\\3w-w+4=5w-2w+4\\\\2w+4=3w+4\\\\3w-2w=4-4\\\\w=0[/tex]
Again we get a unique solution to the equation.
c)
[tex]7y+9=7y-6[/tex]
on subtracting 7y from both the sides of the equation we have:
[tex]7y-7y-6=9\\\\-6=9[/tex]
which is a false identity.
Hence, the equation has no solution.
d)
[tex]4z+8=-4z-2\\\\i.e.\\\\4z+4z=-2-8\\\\8z=-10\\\\z=\dfrac{-10}{8}\\\\z=\dfrac{-5}{4}[/tex]
This equation has a unique solution.
Identify any zeros of y=x^2+4x+5.
A. There are no zeros.
B. (5,0),(4,0)
C. (-1,0),(-3,0)
D. (0,0)
The given quadratic equation y=x^2+4x+5 has no real solutions because the discriminant is negative. Therefore, there are no zeros for this equation, making option A (There are no zeros) the correct choice.
Explanation:The question asks to identify any zeros of the quadratic equation [tex]y=x^2+4x+5.[/tex]To find the zeros, we need to set the equation equal to zero and solve for x. This is typically done using the quadratic formula, which is √x=(-b±√(b^2-4ac))/(2a), where a=1, b=4, and c=5 in our equation.
Substituting these values into the quadratic formula gives: x=(-4±√((4)^2-4*1*5))/(2*1) = (-4±√(16-20))/2 = (-4±√(-4))/2. Since the value under the square root sign (the discriminant) is negative, this equation has no real solutions. Thus, there are no zeros for the given quadratic equation, making option A the correct choice.
helpppp :( 3(x-1) = 2x+9
x equals 12 because
3x-3= 2x+9
x=12
3(x-1) = 2x+9 Remove the Brackets on the left
3x - 3 = 2x + 9 Add 3 to both sides
3x = 2x + 9 + 3 Collect like terms
3x = 2x + 12 Subtract 2x from both sides.
3x - 2x = 2x-2x + 12
x = 12

If a car averages 23.2 miles per gallon of gasoline, how far can it go on 15.25 gallons?
The car goes 23.2 miles every gallon, so with 15 gallons (15 * 23.2 = 348) it can go 348 miles. With the extra .25 that the car has, it can go 0.25 * 23.2 = 5.8 miles. 348 miles plus the 5.8 miles gets you 353.8 miles on 15.25 gallons.
A car that averages 23.2 miles per gallon can travel approximately 353.8 miles using 15.25 gallons of gasoline.
If a car averages 23.2 miles per gallon of gasoline, we can calculate the distance it can travel on 15.25 gallons by multiplying the car's fuel efficiency by the amount of gasoline.
To find the distance:
Multiply the car's average miles per gallon (MPG) by the number of gallons of gasoline.
Distance = 23.2 MPG * 15.25 gallons
Distance = 353.8 miles
Therefore car that averages 23.2 miles per gallon can go approximately 353.8 miles on 15.25 gallons of gasoline.

Explain why the point (0,-5) is not located in quadrant IV
The point (0,-5) is not located in Quadrant IV because it has a negative y-coordinate.
Explanation:The point (0,-5) is not located in Quadrant IV because Quadrant IV is the bottom-right quadrant of the coordinate plane, where both the x-coordinate and the y-coordinate are positive. In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative. A coordinate point with a negative y-coordinate would be located in Quadrants III or IV.

Natalie and her friends decided to rent 4 lanes at regular cost for a party. Ten people need to rent shoes, and 4 people are members. What is the total cost for the party?
I’ve had this question back when i was in school.
You have to calculate at regular price.
4 x 9.75 = 39
Subtraction time. 10 people are renting, 4 are members
10 - 4 = 6
6 that are nonmembers. 4 members
6 x 3.95 = 23.70
4 x 2.95 = 11.80
Add all those up.
39 + 11.80 + 23.70 = 50.80 + 23.70 = 74.50
Answer: $74.50 :)
