<h2>
$ 108.5
</h2>
Explicación paso a paso:
Paso uno:
datos dados
el costo de un metro de cinta tricolor = $ 15.5.
se nos dice que un lazo necesitará 3,5 m de cinta, ya que tu madre hizo dos lazos, usó un total de 3,5 * 2 = 7 m de cinta
Segundo paso:
ahora calcularemos el dinero que gastó su madre.
si 1 m le costará $ 15.5
entonces 7 millones le costarán $ x
Cruz multiplicar tenemos
x = 15,5 * 7
x = $ 108.5
<u>Esto significa que tu madre gastará $ 108.5 para hacerte los dos moños.</u>
Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
Answer:
x= 35000
y= 19000
Step-by-step explanation:
The investment in this question divided into two parts, first who earns 5.5% interest(X) and second who have 4% interest (Y).
The total interest gained is $2685 so you can get this equation.
0.055 x + 0.04 y = 2685
Both x and y sum is $54,000 so you can get this equation
x + y = 54,000
y=54000- x
If you combine both equations
0.055 x + 0.04 y = 2685
0.055 x + 0.04 (54000- x) = 2685
0.055 x + 2160- 0.04x = 2685
0.015x= 2685- 2160
0.015x= 525
x=35000
y=54000- x
y= 54000-35000
y=19000
Answer:
<u>76 in²</u>
Step-by-step explanation:
<u>Area of the figure</u>
- Area (top rectangle) + 2 x Area (bottom rectangle)
- 12 x (7 - 2) + 2 x 2 x 4
- 12 x 5 + 16
- 60 + 16
- <u>76 in²</u>
