Answer:

$3780

Step-by-step explanation:

Salary per month = $10500

Expense on food

= 36% of the monthly salary

= 36% of $10500

= (36/100) × $10500

= 36 × $105

= $3780

So, they spend $3780 on food per month.

4. DECK is a parallelogram. Find the values of x and y.
Darya [45]

Answer:

The value of  x  = 5 and y = 2.

Step-by-step explanation:

Here, given DECK is a parallelogram.

Also, KT = 2x + y  , DT = x + 2y  , TE = 12   and TC = 9

Now, in parallelogram:

DIAGONALS IN A PARALLELOGRAM BISECT EACH OTHER

Also, in the parallelogram DECK,

Sides DC and KE are two diagonals.

⇒ T is the mid point of AC and KE.

⇒ KT = TE and DT = TC ( as diagonals are bisected)

⇒  2 x +   y =  12 and x  +  2y = 9

So here, the set of two equations are:

2 x +   y = 12  ....... (1)

x  +  2 y = 9  ....... (2)

Multiply (2) with -2 and add with (1), we get:

2 x +  y  - 2 x - 4 y = 12  - 18

or, - 3 y = - 6

or, y = 2

If y = 2, then x  +  2 (2) = 9 or, x  = 5

Hence the values of  x  = 5, y = 2

I need helpWith this problemFor my grandson. I did get some help but need more. Thank you!
Pani-rosa [81]

Step 1:

Percent is part of 100.

Step 2

First part:

60 units split into 80% and 20%

\begin{gathered} 80\text{ \% of 60 units = }\frac{80}{100}\text{ }\times60\text{ = 48} \\ 20\text{ \% = 12} \end{gathered}

Second part

12 units = 40 %

\begin{gathered} 40\text{ \% = 12 units } \\ 60\text{ \%  = }\frac{60\times12}{40}\text{ = 18 units} \end{gathered}

Third part

30 % = 18 units

\begin{gathered} 30\text{ \%  =  18 units} \\ 70\text{ \%  = }\frac{18\text{ }\times\text{ 70}}{30}\text{ = 42 units} \end{gathered}

Fourth part

75 % = 42 units

\begin{gathered} 75\text{ \%  =  42 units} \\ 25\text{ \%  =  }\frac{25\text{ }\times\text{ 42}}{75}\text{ = 14 units} \end{gathered}

Final answer

14 + 42 = 56 units

The length of the bottom diagram = 56 units

Please help me, thanks if you do
Olenka [21]

Answer:

y= -28

Step-by-step explanation:

x -y = 11

if x= -17 then substitute x for -17

-17 -y = 11; add 17 to both sides

-17 + 17 -y = 11+ 17; combine like terms

-y = 28; multiply both sides by -1

y= -28

Can you please help me ?
Andrei [34K]
What you can do for this case is to use the following trigonometric definition.
 Tan (x) = a / b
 Where,
 a: opposite side of the triangle.
 h: adjacent side of the triangle.
 Clearing x:
 x = Atan (a / b)
 Substituting:
 x = Atan (a / b)
 x = Atan (5.74 / 4)
 x = 55.12874356
 Whole degree
 x = 55
 Answer:
 x = 55 (option 3)
