A 13tf.ladder is leaning against the house. The top of the ladder touches the house at 10 feet above the ground.How far away is the bottom of the ladder from the house?(draw yourself a picture and label it)
Answers
Answer:
Step-by-step explanation:
I believe youd be using pythagorean theorem here. I hope this helps
The bottom of the ladder from the house is 8.30 feet away.
What is Pythagoras Theorem?The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
H= 13 feet
P= 10 feet
Using Pythagoras Theorem
B = √ H² - P²
H = √13² - 10²
B= √ 169- 100
B= √69
B= 8.30 feet
Hence, the bottom of the ladder from the house is 8.30 feet away.

What is the equation of the line that includes the points (1,6) and (2,8)?
Answers
Answer: y = 2x + 4
Step-by-step explanation:
y = mx + b
(1,6) and (2,8)
Finding Slope:
(8 - 6) / (2 - 1)
=> 2/ 1 or 2
y = 2x + b
Finding "B":
y = 2x + b
=> 6 = 2(1) + b
=> 6 = 2 + b
=> b = 4
so y = 2x + 4

Calcule o saldo de salário, o funcionário foi admitido em 10 de janeiro como mensalista, salário R$ 1400,00?
Answers
Responda:
$ 980
Explicação passo a passo:
Dado que:
Salário mensal = $ 1400
Data de emprego = 10 de janeiro
Usando o sistema de mês de 30 dias:
Taxa diária =. $ 1400/30 = $ 46.66666
Dias não trabalhados = janeiro - 9 de janeiro = 9 dias
Subtraia o salário de 9 dias do total:
Salário total - (9 * taxa diária)
$ 1400 - (9 * $ 46,66666)
$ 1400 - $ 420
= $ 980
Portanto, o saldo do salário é de $ 980

The value of a piece of land deprecates at a rate of 0.60 per year after three years land is worth 2500 what was the original value of the building
Answers
Well, there is actually a formula for this kind of exercises:
n is the price the land had in the third year year
2500=n-nx0.6
2500=n(1-0.6)
2500=nx0.4
n=2500:0.4
n=6250
m is the price the land had in the second year
6250=m-mx0.6
6250=m(1-0.6)
6250=nx0.4
p=6250:0.4
p=15625
p is the price the land had in the first year
15625=p-px0.6
15625=p(1-0.6)
15625=px0.4
p=15625:0.4
p=39,062.5 <- this should be your answer. Hope this helps.

What is the product of (3x + 1)(3x – 4)?
Step by step.
Answers
Answer:
9x^2-9x-3
Step-by-step explanation:
3x*3x=9x^2
3x*-4=-12x
1*3x=3x
1*-4=-3
9x^2-12x+3x-3
9x^2-9x-3
Answer:
9x^2 - 9x - 4
Step-by-step explanation:
(3x + 1)(3x – 4)
Here you can use the FOIL method (FOIL stands for: First, Outer, Inner and Last)
First you multiply 3x by 3x since these are the First inside both binomials.
3x * 3x = 9x^2
Then you multiply 3x by -4 since these are the Outer inside both binomials.
3x * -4 = -12x
Then you multiply 1 by 3x since these are the Inner inside both binomials.
1 * 3x = 3x
Then you multiply 1 by -4 since these are the Outer inside both binomials.
1 * -4 = -4
And finally add everything together:
9x^2 + (-12x) + 3x + (-4)
Since adding a negative number is the same as subtracting it:
9x^2 - 12x + 3x - 4
We can now simplify this a little by adding all the x's together:
9x^2 - (12x + 3x) - 4 =
9x^2 - 9x - 4

because use dimas ruleonly like terms can be subtract and addIf I have 50 envelopes I put equal amounts of money in each one how much will I have at the end of 50 days
Answers
Answer:
At the end of 50 days , Amount of money = $2500x
where x is the value that added every day.
Step-by-step explanation:
Let daily amount added in 1 envelope = $x
As, we have 50 envelope,
so, daily added amount in 50 envelope = $ 50x
⇒ Each day , we add money = $ 50 x
After 50 day, it becomes $50×50x = $2500x
For example -
If we add $ 1 every day in each envelope
then ,
Total amount added in 50 envelope each day = $50×1 = $ 50
Then,
After 50 days,
Total amount = $ 50×50 = $2500
∴ we get
At the end of 50 day, total amount we have = $2500
