Tell whether the rates are equivalent. 0.4 kilometer for every 15 minutes 0.6 kilometer for every 20 minutes
Answer:
no they are not equivalent
Step-by-step explanation:
0.4/15 = 0.026
so for every minute they travel 0.026km
0.6/20 = 0.03
so for every minute they travel 0.03km
so they are not the same/equivalent
Write an equation to represent the problem, be sure to explain the meaning of any variables you use, Jaden dog was 5 and a half inches tall when it was a puppy, now her dog is 14 and a half inches taller than that, how tall is the dog now
Answer:
The dog is 20 inches tall now.
Step-by-step explanation:
Given that:
Height of dog when it was a puppy = [tex]5\frac{1}{2}[/tex] inches
Height of dos now = [tex]14\frac{1}{2}[/tex] than previous height
It means that we will add this height in the height of dog when it was a puppy.
Height of dog now = [tex]5\frac{1}{2}+14\frac{1}{2}[/tex]
Height of dog = [tex]\frac{11}{2}+\frac{29}{2}=\frac{11+29}{2}=\frac{40}{2}[/tex]
Height of dog = 20 inches
Hence,
The dog is 20 inches tall now.
What is the solution to the system of equations below? {2y=x+63x=y+7 (5, 4) (20, 13) (13, 20) (4, 5)
Answer:
(4,5)
Step-by-step explanation:
Let's solve your system by substitution.
2y=x+6;3x=y+7
Step: Solve2y=x+6for x:
2y=x+6
2y+−x=x+6+−x(Add -x to both sides)
−x+2y=6
−x+2y+−2y=6+−2y(Add -2y to both sides)
−x=−2y+6
−x
−1
=
−2y+6
−1
(Divide both sides by -1)
x=2y−6
Step: Substitute2y−6forxin3x=y+7:
3x=y+7
3(2y−6)=y+7
6y−18=y+7(Simplify both sides of the equation)
6y−18+−y=y+7+−y(Add -y to both sides)
5y−18=7
5y−18+18=7+18(Add 18 to both sides)
5y=25
5y
5
=
25
5
(Divide both sides by 5)
y=5
Step: Substitute 5 for y in x=2y−6:
x=2y−6
x=(2)(5)−6
x=4(Simplify both sides of the equation)

dan pays £714.73 a year on his car insurance
the insurance company reduces the price by 4.1%
how much does the insurance cost now?
give your answer rounded to 2DP
Answer:
The Current Insurance cost = $685.43
Step-by-step explanation:
Given that Dan pays £714.73 a year on his car insurance.
Reduced Percentage = 4.1%
so
Reduced Amount = 4.1% × 714.73
= [4.1 / 100] × [714.73]
= 0.041 × 714.73
= $29.30
The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.
so
Current Insurance cost = 714.73 - 29.30
= $685.43
Therefore, the Current Insurance cost = $685.43

Subtract 7 from the product 3 times f
Answer:
3*f-7
Step-by-step explanation:
OK; "subtract from" means to do the "from" first and then subtract the number off of the "from." In this case, the "from" is 3*f. Then, subtrat seven. That gives you 3*f-7. No need for parenthesis because of PEMDAS.

One hundred people in your neighborhood always drive to work between 7:30 and 8:00 A.M. and arrive 30 minutes later. Why must two people always arrive at work at the same time, within a minute
Answer: Pigeonhole Principle
Step-by-step explanation:
The Pigeonhole Principle espouses that if there are more objects than the places the objects are supposed to fit into, some of those places will have more than one object. For instance, if there are 20 pigeons and only 19 pigeonholes, one pigeonhole will have more than one pigeon.
If one hundred people in your neighbourhood leave between 7:30 and 8:00 A.M. and arrive 30 minutes later that means they will arrive between 8:00 and 8:30 A.M. This means that 100 people will have to arrive in 30 minutes.
We would have to fit 100 people in 30 minutes. The minutes are the pigeonholes and the people are the pigeons. There will therefore be a situation where at least 2 people will arrive at the same minute because there are many more people than minutes for them to arrive in.

Find the degree of the term -5x to the power of 4
Answer:
4 or -625x^4 (Just in case I misunderstood)
Step-by-step explanation:
The degree is always the power of something. Since -5x has a power of 4, its degree is 4.
Just in case I misunderstood the question, I will solve it another way that I think you meant. (-5x)^4 is -5^4 times x^4.
-625 times x^4 is -625x^4.

12.5 x 13 estimate i dont know how to do it XD I need help
Answer:
162.5
Step-by-step explanation:
Hope this helps Please brainiest
Answer:
Ok the answer is 162.5 but if you wanna learn how to do it, look at the explanation! :D
Step-by-step explanation:
To make it easy, you can split the 12.5 into 10 and 2.5, now that you have done that, multiplication is made easy! Multiply the 10 by 13 which gets you 130. Then, multiply the 2.5 by 13 to get 32.5, now add 130 and 32.5 together to get your answer, which in this case is 162.5! Hope this helped and I hope you have a magnificent day! :D

Express (x + 10)^2 as a trinomial in standard form.
Answer:
x2-20x+100
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
The required trinomial in standard form is x²+20x+100.
Trinomial:Important information:
The expression is the [tex](x+10)^2[/tex].Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+10)^2=(x)^2+2(x)(10)+(10)^2[/tex]
[tex](x+10)^2=x^2+20x+100[/tex]
Therefore, the required trinomial in standard form is x²+20x+100.

What is the value of x when g(h(x)) = 4?
Answer:4
Step-by-step explanation:
I Took the test
The value of the x in g(h(x)) = 4 is 4 if the g⁻¹(4) = 2 and at x = 4 h(x) = 2 option (C) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have functions g(x) and h(x) shown in the figure.
g(h(x)) = 4
Taking the inverse of a function:
h(x) = g⁻¹(4)
From the set of functions g(x)
(2, 4) belongs to g(x)
(4, 2) belongs to g⁻¹(x)
g⁻¹(4) = 2
h(x) = 2
x = 4 (from the function h(x) data set)
Thus, the value of the x in g(h(x)) = 4 is 4 if the g⁻¹(4) = 2 and at x = 4 h(x) = 2 option (C) is correct.

What is the value of x?
Answer:
13-4y
Step-by-step explanation:
Without a second equation it is impossible to give a numerical value for x, but x can be expressed in terms of y.
This equation is called a "literal equation" since there are more than one variable, but only one equation (it is not a system of equations).
Therefore, solve for x by subtracting 4y from both sides:
x+4y=13
-4y -4y
x=13-4y
Answer:
Hi! The correct answer is x=13-4y!
Step-by-step explanation:
~Subtract 4y from both sides of the equation~
