If they all painted at the same rate the equation is this 

mothers 8
daughters 12  at 220 sq ft


mothers 6
daughters 8 at 152 sq ft

220 +152 =372 divided by 34 (because they all painted at the same rate)=10.94 sq ft they each painted

El ancho de un rectángulo es 15 pies menos que
Karolina [17]

Answer:

II. Longitud, L = 70 metros.

I. Ancho = 55 metros.

Step-by-step explanation:

Deje que la longitud del rectángulo sea L.

Deje que el ancho del rectángulo sea W.

Dados los siguientes datos;

Perímetro del rectángulo = 250 m

Traduciendo el problema verbal a una expresión algebraica, tenemos;

W = L - 15

Matemáticamente, el perímetro de un rectángulo viene dado por la fórmula;

P = 2 (largo + ancho)

250 = 2 (L + L - 15)

250 = 2 (2L - 15)

250 = 4L - 30

4L = 250 + 30

4L = 280

L = 280/4

Longitud, L = 70 m

Para encontrar el ancho;

W = L - 15

W = 70 - 15

Ancho = 55 m

Round each number to the nearest ten. What is the best estimate for the answer to 343.42 – 39.87?
Dafna11 [192]
The original answer for that question would be 303.55. The best estimate when you round to the nearest tenth the approximate answer would be 303.6 because the 5 in the hundredths place rounds the 5 in the tenths place to a 6. So the approximate answer would be 303.6....hope this helps.

find the volume of the cone. either enter exact answer in terms of pi or use 3.14 for pi and round your final answer to the near
SCORPION-xisa [38]

Answer:

6\pi u^3 = 18.8u^3

Step-by-step explanation:

the information we have is:

  • the radius of the circle in the base: r=3u (u for units)
  • and the height of the cone: h=2u

to find the volume we need the formula for the volume of a cone:

V=\frac{\pi r^2h}{3}

where r is the radius and h is the height.

Substituting the known values to find the volume:

V=\frac{\pi (3u)^2(2u)}{3} \\\\V=\frac{\pi (9u^2)(2u)}{3}\\ \\V=\frac{18\pi u^3}{3}\\ \\V=6\pi u^3

the volume in terms of \pi is 6\pi u^3

and if we substitute the value of pi: \pi=3.14 we get:

V=6(3.14)u^3\\V=18.8u^3

iogann1982 [59]

Answer:

0.1469

Step-by-step explanation:

Given from the question;

Mean=8.4 hrs=μ

Standard deviation=1.8 hrs=δ

Sample size, n=40

Let  x=8.7

z=(x-μ)÷(δ÷√n)  

Find z(8.7)

z=(8.7-8.4)÷(1.8÷√40)

z={0.3×√40}÷1.8=1.05409

z=1.0541

Read from the  standard normal probabilities table

P(z>1.0541)

=0.1459
