Answer:

80

Step-by-step explanation:

82-12+10

82+10-12

92-12

80

The number of people in the restaurant will be 80

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that there are 82 people in a restaurant. Four groups of 3 leave and then five groups of 2 enter.

The expression will be solved as below:-

E = 82-12+10

E = 82+10-12

E = 92-12

E = 80

Therefore, the number of people in the restaurant will be 80

Answer:

$605

Step-by-step explanation:

The correct question is

Taho Earns His Regular Pay Of $11 Per Hour For Up To 40 Hours Of Work Per Week. For each hour over 40 hours of work per week. Taho earns 1½ times his regular pay. How much does Taho earn in a week in which he works 50 hours?

a. $550

b. $605

c. $625

d. $750

e. $825

For the first $40 that Taho works, he earns $11 x 40 = $440

For the extra $10 (since he worked 50 hrs that week)

1½ of $11 per hr = 1.5 x $11 = $16.5

for the 10 days extra = $16.5 x 10 = $165

total pay = $440 + $165 = $605

Answer:

que????? no entiendo??????

Answer:

The possible midpoints of AB are [tex]\frac{19}{2}[/tex] and [tex]\frac{13}{2}[/tex].

Step-by-step explanation:

Let suppose that A and B have one-dimensional coordinates. GIven that [tex]A = 8[/tex] and [tex]AB = 3[/tex], there are two possible locations for B:

[tex]B_{1} = A+AB[/tex]

[tex]B_{1} =8+3[/tex]

[tex]B_{1} = 11[/tex]

[tex]B_{2} = A-AB[/tex]

[tex]B_{2} = 8-3[/tex]

[tex]B_{2} = 5[/tex]

The midpoint equations for each case are, respectively:

[tex]m_{1} = \frac{A+B_{1}}{2}[/tex]

[tex]m_{1}=\frac{8+11}{2}[/tex]

[tex]m_{1} = \frac{19}{2}[/tex]

[tex]m_{2} = \frac{A+B_{2}}{2}[/tex]

[tex]m_{2} = \frac{5+8}{2}[/tex]

[tex]m_{2} = \frac{13}{2}[/tex]

The possible midpoints of AB are [tex]\frac{19}{2}[/tex] and [tex]\frac{13}{2}[/tex].

Answer:

(0, 6)

Step-by-step explanation:

Point T has a coordinate pair of (3, 4). That is, at point T, x = 3, while y = 4.

3 points to the left of T would be a movement on the x-axis. This movement is a run across the x-axis. At T, x = 3. Therefore, 3 points to the left would be a decrease by 3 = 3 - 3 = 0.

3 points to the left of T would leave us with an x coordinate of 0.

2 points above T suggest a rise, which is on the y-axis.

Therefore, at T, y = 4. 2 points above 4 = 4 + 2 = 6. y coordinate would now be 6.

In conclusion, the ordered pair representing 3 points to the left, and 2 points above point T is (0, 6).

Answer: m=6

Step-by-step explanation:

[tex]9+12m=6+15\left(m-1\right)[/tex]

[tex]6+15\left(m-1\right)=15m-9[/tex]

[tex]9+12m=15m-9[/tex]

subtract 9 on both sides

[tex]9+12m-9=15m-9-9[/tex]

[tex]12m=15m-18[/tex]

subtract 15m on both sides

[tex]12m-15m=15m-18-15m[/tex]

[tex]-3m=-18[/tex]

divide by -3 on both sides

[tex]\frac{-3m}{-3}=\frac{-18}{-3}[/tex]

since [tex]\frac{-a}{-b}=\frac{a}{b}[/tex]

[tex]\frac{-18}{-3}=6[/tex]

[tex]m=6[/tex]

Answer:

0.06 cubic meters per year...

Step-by-step explanation:

The rate of water flows through a pipe is 0.06 cubic meters per year.

It is the volume of fluid flows out from the container per unit time.

Given that,

Water flows through a pipe at a rate of 6 fluid ounces per day. It can be written as:

Water flows per day ⇔ 6 fluid ounces

∴ Water flows per year ⇔  365 x (6 fluid ounces)

Volume of water in milliliter,

Water flows per year ⇔  365 x (6 x 29.574 ml )

Volume of water in cubic meter,

Water flows per year ⇔  365 x ([tex]\frac{6 x 29.574}{1000000}[/tex] [tex]m^{3}[/tex]) = 0.06477   [tex]m^{3}[/tex]

Hence Water flows per year round value to the nearest hundredth is 0.06  [tex]m^{3}[/tex].

Answer:

(- 1, 8 )

Step-by-step explanation:

Under a reflection in the line y = x

a point (x, y ) → (y, x ) , thus

(8, - 1 ) → (- 1, 8 )

The image of (8, -1) after a reflection over the line y = x is, (- 1, 8).

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

We have to given that;

A point (8, - 1) is reflected over the line y = x.

Now, We know that;

The image of point (x, y) after reflection over the line y = x is,

⇒ (x, y) → (y, x)

Thus, The image of (8, -1) after a reflection over the line y = x is,

Step-by-step explanation:

The reciprocal of a fraction can be found by flipping the numerator (top number) and denominator (bottom number).

The number 6 is equivalent to the fraction 6/1.

Find the reciprocal of 6/1. Invert the numerator and denominator.

6/1 ⇒ 1/6

The reciprocal of 6 is 1/6

Answer:

a) 820

b)450

c)  -540

d) -294

e) 1440

f) 1425

Step-by-step explanation:

a) it is an arithmetic progression with ratio=4

   a1=3,

     a2=3+r=3+4=7.....

    a20=a1+19r

so a20=3+19*4=3+76=79

S=(a1+an)*n/2 where n=20

so S=(3+79)*20/2=820

b) a15=a1+14*r=2+14*4=2+56=58

S=(a1+a15)*15/2=(2+58)*15/2=60*15/2=30*15=450

It is the same formula for all  the exercises

S=(a1+an)*n/2 ,     where n is the number of terms

c) a40=30+39*(-3)=30-87=-57

So S=(30-57)*40/2=-540

d) a14=5+13*(-4)=5-52=-47

S=(5-47)*14/2=-42*14/2=-42*7=-294

e) it is 5+7+9+......+75

nr of  terms  = (an-a1) :r+1=(75-5):2+1=36

S=(5+75)*36/2=36*40=1440

f) ratio=7-4=3

the  same formula for n= (91-4):3+1=87:3+1=29+1=30

S=(4+91)*30/2=95*30/2=2850/2=1425
