A rectangular city lot has an area of 1000 square meters. If the length of the lot is 10 meters more than twice its width, find its length and width.
Answer: l=50 m, w=20 m
Step-by-step explanation:
Given
A rectangular city has an area of [tex]1000\ m^2[/tex]
Also, length is 10 m more than twice its width
suppose width is w
So, length is given by
[tex]\Rightarrow l=10+2w[/tex]
The area is given by
[tex]\Rightarrow A=l\times w\\\Rightarrow 1000=(10+2w)\times w\\\Rightarrow 2w^2+10w-1000=0\\\Rightarrow w^2+5w-500=0\\\Rightarrow w^2+25w-20w-500=0\\\Rightarrow (w+25)(w-20)=0\\\therefore w=20\ m\\l=10+2w=10+2\times 20=50\ m[/tex]

f(x)= x^2 - 7x +12
The above equation is in standard form. Write the above equation in factored form
f(x) = (x-r1)(x-r2)
r1 represents first root, r2 represetnts second root
What are the roots?
Remember, x-r1 = 0 and x-r2=0
Answer:
f(x) = (x - 3)(x - 4)
Step-by-step explanation:
f(x)= x^2 - 7x +12 factors immediately into f(x) = (x - 3)(x - 4).
The roots are {3, 4}

Math 8th Grade
Answer:
B = -1
Your answer would be C
Answer:
b = -1
Step-by-step explanation:
-3(2x - 3) + 5x = bx + 9
-3 x 2x = -6x
-3 x -3 = 9
-6x + 9 + 5x = bx + 9
-6x + 5x = -1x
-1x + 9 = bx + 9
(cancel out everything except -1 and b)
-1 = b

Theresa rolls a 12-sided dice and flips a
coin. What is the probability that she will
roll a 7 and land on heads?
Answer:
The probability is 1/24
Step-by-step explanation:
For a 12-sided dice, there are 12 different possible results
so the possibility of rolling a 7 is just one of the results
The probability of this is simply 1/12
For landing on head, the probability is 1/2
So the probability of the event occurring is the product of these two events
We have this as;
1/2 * 1/12 = 1/24

A plumber charges $75 for the service call and $25 per hour (h) for repairs. Write an algebraic expression to represent the total bill for all plumbing services.
A.
(75 + 25)h
B.
75 + 25h
C.
75h + 25
D.
75 + 25 + h
Answer:B i think if wrong im so sorry
Step-by-step explanation:
Answer:
B 75+25h
Step-by-step explanation:
$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

what is the product of 4n/4n-4 * n-1/n+1
Answer:
x/x+1
Step-by-step explanation:
[tex]\frac{4n}{4n-4} * \frac{n-1}{n+1}[/tex]
start by reducing the 4n-4 by distributing the 4 to make it 4(x-1)
So the fraction would be 4n/4(x-1)
Now that you have done that you can easily take off the 4 as well as the x-1 thats now in the parentheses
The new equation would be
n*n-1/n+1
Now just multiply:
x/x+1
Answer:
B.) n/(n+1)

Josh is going to the store with $60 to buy candy. bags of candy corn cost $3 & bags of chocolate cost $5 he needs to buy at least 20 bags of candy.
What do I put for the blank space? 3x+5y_60
Answer:
3a+5b
Step-by-step explanation:
Variable 1: a = candy corn
Variable 2: b = chocolate
Inequality 1: 60 ≥ 3a + 5b
Inequality 2: 20 ≤ 3a + 5b
The inequalities are as such because Josh needs to spend no greater than $60. He must also buy at least 20 bags of candy. The candy corn costs $3, while the chocolate costs $5. An expression for the total cost of the candy would be 3a + 5b.
what is 2.1 times 3.2 find the missing partial products HELP.
Given:
The area model for [tex]2.1\times 3.2[/tex].
To find:
The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:
[tex]2\times 3=6[/tex]
[tex]2\times 0.2=0.4[/tex]
[tex]0.1\times 3=0.3[/tex]
[tex]0.1\times 0.2=0.02[/tex]
The complete area model is shown below.
After adding all areas of the area model, we get
[tex]6+0.4+0.3+0.02=6.72[/tex]
Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

Answer:
m<A=94
Step-by-step explanation:
(2x+10)+(2x+2)=180
4x+12=180
-12 -12
4x=168
/4 /4
x=42
m<A= 2x+10
m<A=2(42)+10
m<A=84+10
m<A=94
Check:
Add m<A and m<B which should equal 180.
m<B=2x+2
m<B=2(42)+2
m<B=84+2
m<B=86
94+86=180
Which of these sequences shows the flow of energy from the sun through organisms on Earth?
1 sun → producer → consumer → decomposer
2 sun → consumer-producer → decomposer
Answer:
I'm pretty sure it's number 1. The sun goes to plants and the plants get consumed. I don't think that the consumer eats the sun... just kidding. But yeah it's the first one.
1 sun → producer → consumer → decomposer
Uma fábrica que produz pnes transporta seus produtos em caminhões para a central de distribuição. Cada caminhão tem capacidade de levar até 456 pneus. Em 5 viagens, com capacidade mãxima, serão transportados quantos pneus?
Responder:
2280 pneus.
Explicação passo a passo:
Dado que :
Número máximo de pneus que o caminhão pode transportar de uma vez = 456
Se o caminhão fizer 5 viagens;
O número de pneus que serão transportados na capacidade máxima é:
Capacidade máxima do caminhão * número de viagens
456 * 5
= 2.280 pneus.

A grocery store recently sold 12 cans of soup, 6 of which were black bean soup. Based on experimental probability, how many of the next 20 cans sold should you expect to be black bean soup?
Answer: 10
Step-by-step explanation: the probability of selling black bean soup is 1/2 because 6/12=1/2. You should multiply 20 by 1/2 to find how many of the next 20 are expects to be black bean.
