Entre Pedro y su hermana Ana han ahorrado $ 810. Pedro ha ahorrado $150 más que Ana. ¿Cuánto dinero ha ahorrado cada uno? NECESITO LA RESPUESTA CON SISTEMA DE ECUACIÓN 2 X 2, POR FAVOR.
Answers
Answer:
Pedro ahorró: $ 480
Ana ahorró = $ 330
Step-by-step explanation:
Vamos a representar
La cantidad que Pedro ahorró = x
La cantidad que Ana ahorró = y
Por eso,
x + y = $ 810 ...... Ecuación 1
Pedro ha ahorrado $ 150 más que Ana
x = 150 + y
Por lo tanto, sustituimos x por 150 + y
150 + y + y = 810
150 + 2y = 810
2 años = 810 - 150
2 años = 660
y = 660/2
y = $ 330
Resolviendo para x
= x = 150 + y
x = $ 150 + $ 330
x = $ 480
Por lo tanto,
Pedro ahorró: $ 480
Ana ahorró = $ 330

Claude has 7 paintings and he can paint 2 every week.
Clint has 10 paintings and he takes 2 weeks to paint
1 picture. How many weeks (w) will it be before Claude
has as many paintings as Clint?
Answers
Representing the word problem as an equation, it will take 2 weeks for them to have the same number of painting.
Representing the problem with equationnumber of weeks = w
Claude's painting after w weeks can be written thus ;
7 + 2w
Clint's painting after w weeks can be written thus ;
10 + 0.5w
Equating both expression:
7 + 2w = 10 + 0.5w
Collect like terms :
2w - 0.5w = 10 - 7
1.5w = 3
w = 3/1.5
w = 2
Hence, it will take 2 weeks for them to have the same number of painting.

O D. 11

Answers
============================================================
Work Shown:
The triangle has the given angles A = 45 and B = 89
Let's find angle C
A+B+C = 180
C = 180-A-B
C = 180-45-89
C = 46
----------------
Segment BA, or side c, is opposite angle C
Segment AC, or side b, is opposite angle B
So we have this known info:
angle B = 89side b = 15angle C = 46Apply the law of sines to find c. Make sure your calculator is in degree mode.
sin(B)/b = sin(C)/c
sin(89)/15 = sin(46)/c
c*sin(89) = 15*sin(46)
c = 15*sin(46)/sin(89)
c = 10.7917406394501
c = 10.8

A DVD with a radius of 6 centimeters rotates at a speed of 243 revolutions per minute. Find the liner speed in centimeters per second.
Answers
Answer:
152.7 cm/s
Step-by-step explanation:
The radius of DVD, r = 6 cm
The angular speed of DVD, [tex]\omega=243\ rev/min=25.45\ rad/s[/tex]
We need to find the linear speed of the DVD.
The relation between linear speed and angular speed is given by :
[tex]v=r\omega\\\\v=0.06\times 25.45\\\\v=1.527\ m/s[/tex]
or
v = 152.7 cm/s
So, the linear speed of the DVD is 152.7 cm/s.

You have been told to make 144 two ounce chocolate chip cookies for a banquet . The recipe yields three pounds of cookie . By what factor would you need to increase the recipe
Answers
Answer: 6
Step-by-step explanation:
You have been told to make 144 two ounce chocolate chip cookies so the total weight of those cookies is:
= 144 * 2
= 288 ounces
A pound is equivalent to 16 ounces.
The recipe yields 3 pounds of cookies which is:
= 3 * 16
= 48 ounces
For the recipe to make 288 ounces, you need to scale up by:
= 288 / 48
= 6
