Answer:

The Average Temperature for the week is -1°C

Step-by-step explanation:

First to find the average, you have to combine all the numbers

-3-4+0-2+0+3-1 = -7

Then you have to divide the total, with the number of numbers used to combine to make the total

-7 ÷ 7 = -1

The average temperature is -1°C

Olivia ate at the same restaurant three times. Each visit, she ordered a

zloy xaker [14]

Answer:

equation: 3e + $6.75 = $39, where e = $10.75, assuming that sandwich = salad

Step-by-step explanation:

Olivia ate 3 times, hence, she tipped a total of $2.25 x 3 = $6.75

Since Olivia spent a total of $39,

3e + $6.75 = $39

(If you want to solve for e:

3e = $32.25

e = $10.75)

Evaluate the integral Integral from 0 to 1 Integral from 0 to 3 Integral from 3 y to 9 StartFraction 6 cosine (x squared )Over 5

Natalka [10]

Answer:

$\int^1_0\int^3_0\int^9_{3y}\frac{6 cos x^2}{5\sqrt z}dxdydz$ $=\frac{18}{5}(1+\frac{sin2}{2})$

Step-by-step explanation:

cosine x²= cos x²

Rule

$\int x^ndx= \frac{x^{n+1}}{n+1}+c$

$\int cos \ mx \ dx = \frac{sin \ mx}{m}+c$
$\int \frac{1}{\sqrt x}dx = \frac{\sqrt x}{\frac{1}{2}} +c= 2\sqrt x+c$

Given that,

$\int^1_0\int^3_0\int^9_{3y}\frac{6 cos x^2}{5\sqrt z}dxdydz$

$=\int ^1_0[\int^3_0(\int^9_{3y} \frac{6cos x^2}{5\sqrt z}dz)dy]dz$

$=\int^1_0[\int^3_0([\frac{6cos x^2 \times \sqrt z}{5\times \frac{1}{2}}]^9_{3y})dy]dx$

$=\int^1_0[\int^3_0([\frac{12cos x^2 \times( \sqrt 9-\sqrt{3y})}{5}])dy]dx$

$=\int^1_0[\int^3_0([\frac{12cos x^2 \times( 3-\sqrt{3y})}{5}])dy]dx$

$=\int^1_0[\frac{12cos x^2 \times( 3y-\frac{\sqrt{3}y^\frac{3}{2}}{\frac{3}{2}})}{5}]^3_0dx$

$=\int^1_0[\frac{12cos x^2 \times( 3.3-\frac{2\sqrt{3}.3^\frac{3}{2}}{3})}{5}]^3_0dx$

$=\int^1_0[\frac{12cos x^2 \times( 9-6)}{5}]dx$

$=\frac{18}{5}\int^1_02cos x^2dx$

$=\frac{18}{5}\int^1_0(1+cos2x)dx$

$=\frac{18}{5}[(x+\frac{sin2x}{2})]^1_0$

$=\frac{18}{5}(1+\frac{sin2}{2})$

Una compañía de fabricación de muebles suele emplear 18 horas para ensamblar 12 muebles. Para determinar el número de muebles qu

uysha [10]

Answer:

The time required is 4.5 hours.

Step-by-step explanation:

A furniture manufacturing company typically takes 18 hours to assemble 12 pieces of furniture. To determine the number of pieces of furniture that will be assembled in 3 hours, the following calculations were proposed; the one that allows to verify this relationship correctly is

The 12 pieces of furniture assembled in 18 hours

So, 1 piece assembled in 18 / 12 hours = 1.5 hours

And 3 pieces assembled in 3 x 1.5 = 4.5 hours
