Van a poner balfosas en una calle que mide 3 hm y 9 dam de largo. Ya han embaldosado 125 m de calle ¿A cuantos metros les falta poner baldosas
Answer:
Faltan 265 metros por embaldosar.
Step-by-step explanation:
Un decámetro equivale a 10 metros, mientras que un hectómetro equivale a 100 metros. A continuación, calculamos la longitud equivalente de calle en metros:
[tex]x = 3\,hm \times \left(\frac{100\,m}{1\,hm} \right)+9\,dam\times \left(\frac{10\,m}{1\,dam} \right)[/tex]
[tex]x = 390\,m[/tex]
La longitud pendiente por poner baldosas es la longitud total menos la longitud ya embaldosada, es decir:
[tex]y = 390\,m-125\,m[/tex]
[tex]y = 265\,m[/tex]
Faltan 265 metros por embaldosar.
A population of 130,000 grows 4% per year for 16 years.
How much will the population be after 16 years?
Let's consider the scenario after each year:
After the zeroth year, the population is: 120 000(1 + 0.04)⁰
After the first year, the population is: 120 000(1 + 0.04)¹
After the second year, the population is: 120 000(1 + 0.04)²
...
Thus, we can find the general rule:
After the nth year, the population is: 120 000(1 + 0.04)ⁿ
And after the 16th year, the population is 120 000(1 + 0.04)¹⁶ = 224 758 (rounded to nearest whole number)

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out the maximum amount of profit the company can make, to the nearest dollar. y=-x^2+62x-410
Answer:
$551
Step-by-step explanation:
Given the amount of profit, y, made by the company, is related to the selling price of each widget, x, by the equation y=-x^2+62x-410
The company make the maximum profit at when dy/dx = 0
dy/dx = -2x + 62
Since dy/dx = 0
0 = -2x + 62
2x = 62
x = 62/2
x = 31
substitute x = 31 into the expression y=-x^2+62x-410
y=-x^2+62x-410
y=-31^2+62(31)-410
y = -961+1922-410
y = 551
Hence the maximum profit the company can make is $551

Taka is playing a game of darts. She scores 52 positive points. She gets a −3 score each time she misses the board. Her final point total is 37. Write and solve an equation to find out how many times she missed the board, x. Enter the correct answers in the boxes.
Answer:
she missed 5 times
Step-by-step explanation:
So she has 52 points already and the final amount was 37.
so each miss is -3 so we can make the amount with “x”
51-3x=37
SOlve and you would get 5 misses
There are 5 times she missed the board.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
She scores 52 positive points.
She gets a '- 3' score each time she misses the board.
And, Total final points = 37
Now,
Let the number of missed the boards = x
So, We can formulate as;
⇒ 52 - 3x = 37
Solve for x as;
⇒ 52 - 3x = 37
⇒ 52 - 37 = 3x
⇒ 15 = 3x
⇒ 3x = 15
⇒ x = 15/3
⇒ x = 5
Thus, There are 5 times she missed the board.

Hiro has 5 kilograms of potatoes and 2 kilograms of onions. He plans to use 3.25 kilograms of potatoes and 550 grams of onions for a recipe. How many total kilograms of the produce will not be used
Answer: 3.20kg
Step-by-step explanation:
Hiro has 5 kilograms of potatoes and 2 kilograms of onions. The total kilogram of the produce will be:
= 5kg + 2kg
= 7kg
Since he plans to use 3.25 kilograms of potatoes and 550 grams of onions for a recipe. The total kilogram that he plans to use will be:
= 3.25kg + 0.55kg
= 3.80kg
Therefore, the total kilograms of the produce will not be used will be:
= 7kg - 3.80kg
= 3.20kg
Note:
1000grams = 1 kilogram
550gram = 550/1000 = 0.55kg

Step-by-step explanation:
The Pythagoras theorem is a² = b² + c² where a is the hypotenuse or longest side
To find the shorter side, the equation is rearranged so c² = a² - b² (whether it is b or c doesn't matter)
so √377² - 277² = 255.7342371

hi im back
find the measure of each angle indicated?
help plz
Step-by-step explanation:
For first you can do like this:
Angle T you can get:
180°-(25°+55°)
180°-80°
100° Angle T
And Angle X is
180°- 100°= 80°
Second one:
First you need to find angle S and you do it like this:
180°-156°= 24°
Then angle R is:
180°-(24°+96°)= 180°-120°=60°

Answer:
3) x = −11
4) x = 40/11 or 3.636363... (it keeps going)
5)
Step-by-step explanation:
3) 5x/6 − ( 2x − 1/2 ) + 4 − 2x/3 = 11
Step 1: Simplify both sides of the equation.
5x/6 − ( 2x−1/2 ) + 4 − 2x/3 = 11
5x/6 + − x + 1/2 + − 2/3x + 4/3 = 11 ( Distribute )
5/6x + − x + 1/2 + − 2/3x + 4/3 = 11
( 5/6x + − x + − 2/3x ) + ( 1/2 + 4/3 ) = 11 ( Combine Like Terms )
−5/6x + 11/6 = 11
Step 2: Subtract 11/6 from both sides.
−5/6x + 11/6 − 11/6 = 11 − 11/6
−5/6x = 55/6
Step 3: Multiply both sides by 6/(-5).
( 6/−5 ) * ( −5/6x ) = ( 6/−5 ) * ( 55/6 )
x = −11
4) 10 - 2x = 3/4x
x = 40/11
(going to also be long I so wont put my work here)
5) -3( x - 3 ) - 9x - 9 = 4( x + 2 ) - 12
