Patrice, por sí solo, puede pintar cuatro cuartos en 10 horas. Si contrata a April para que le ayude, pueden hacer el mismo trabajo en 6 horas. ¿Cuánto tiempo le tomará a April pintar cuatro cuartos si trabaja sola?
Answer:
15 horas
Step-by-step explanation:
Representemos:
El número de horas que Patrice puede pintar solo = P = 10 horas
El número de horas que April puede pintar por su cuenta = A = X horas
El número total de horas que pueden trabajar juntos para hacer el mismo trabajo = T = 6
Por tanto, nuestra fórmula es:
1 / P + 1 / A = 1 / T
1/10 + 1 / A = 1/6
1 / A = 1/6 -1/10
Denominador común más bajo = 30
1 / A = 5 - 3/30
1 / A = 2/30
1 / A = 1/15
Multiplicar cruzada
A × 1 = 15 × 1
A = 15 horas
Por lo tanto, la cantidad de horas que April puede pintar cuatro habitaciones si trabaja sola es de 15 horas.

What is the missing number in the pattern? 9, _____, 35, 48, 61
Answer:
4 there all adding by 13 so do 13-9 to get 4
Answer: 22
Step-by-step explanation: The answer is 22 because all you have to do it keep adding 13 to the number like.
9 + 13 = 22
22 + 13 = 35
35 + 13 = 48
48 + 13 = 61
etc

1.angle 2=92 degree(being vertically opposite angle)
2.angle 1+33+92=180(sum of interior angles of a triangle)
angle 1+125=180
angle 1=180-125
angle 1=55
3.angle 3+angle 2+115+90=360(sum of four angles is always 360 degree)
angle 3+92+205=360
angle 3+297=360
angle 3=360-297
angle 3=63

what is the volume of the square pyramid
Answer:
3710.67 mm
Step-by-step explanation:
The formula is a^2 h/3
a = 22 h = 23
First, do 22 squared which is 484.
Now do 23 divided by 3 which is 7.666666667
Now multiply 484 and 7.666666667 together to get
3710.666667 or 3710.67 mm

What is the length of segment DE?
E
6
50°
D
F
Answer:
x=7.2
Step-by-step explanation:
Tan=O/A
=x/6
Tan50=x/6
×6 on both sides
6× Tan50=7.2
Answer:
DE ≈ 7.2
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{DE}{EF}[/tex] = [tex]\frac{DE}{6}[/tex] ( multiply both sides by 6 )
6 × tan50° = DE , then
DE ≈ 7.2 ( to the nearest tenth )

Answer:
2 2/3
Step-by-step explanation:
I used a calculator. -2.33-(-5)=2.67
Answer:
A
Step-by-step explanation:
It cannot be D, because you are subtracting the whole numbers, or B and D, because the fraction does not change.
So, if you were to solve it, you are just subtracting the whole numbers, and leaving the fraction alone. So the fraction will stay as [tex]\frac{1}{3}[/tex], while you just subtract the whole numbers.
-2+5 = 3
The answer is 3[tex]\frac{1}{3}[/tex]

Hamdan bought a TV for 40000 and sold it for 32000. What is the profit/loss percentage
Answer:
20% loss
Step-by-step explanation:
(32000-40000)/40000 * 100 = -20%
Answer:
Step-by-step explanation:
CP of a TV=40000
Sp of a TV=32000
here CP is greater than Sp so there is loss
loss=CP-SP
=40000-32000
=8000
loss%=loss amount/cp*100%
=8000/40000*100
=800000/40000
=20%

Answer:
y = 4/3x - 2, B is your answer
Step-by-step explanation:
Y intercept is the number next to slope(b).
The co efficient of x will be your slope so therefore the co efficient of x will be 4/3
y is always there because it will always be the dependent variable on the left side.
Answer:
the answer is B
Step-by-step explanation:
Y=(slope)x+y-intercept/y=mx+b
plug in the slope then the Yy intercept

Use a half-angle identity to find the exact value of cos 15º.
Answer:
Step-by-step explanation:
[tex]cos15=cos\frac{30}{2}[/tex] so the angle we will use in our identity is 30 degrees. The formula is
[tex]cos\frac{30}{2}=\sqrt{\frac{1+cos30}{2} }[/tex] which simplifies to
[tex]\sqrt{\frac{1+\frac{\sqrt{3} }{2} }{2} }[/tex] which simplifies to
[tex]\sqrt{\frac{\frac{2+\sqrt{3} }{2} }{2} }[/tex] which simplifies to
[tex]\sqrt{\frac{2+\sqrt{3} }{4} }[/tex] which simplifies, finally, to
[tex]\frac{\sqrt{2+\sqrt{3} } }{2}[/tex], choice a.

Question above
Answer:
6,561
Step-by-step explanation:
Given that;
[tex]log_3x + log_9x = 12\\log_3x+1/2log_3 x = 12\\(1+1/2)log_3x = 12\\3/2log_3x = 12\\log_3x = 12 *2/3\\log_3x = 8\\x = 3^8\\x = 6,561[/tex]
Hence the value of x is 6,561
