The value of y = 40.

5x = 40
  x = 8

180 = 40 + 40 + (2y + 20)
  40 = y

Answer:

Hence, the value of y is:

40

Step-by-step explanation:

We know that angle opposite to equal sides are equal

In given ΔABC we have:

AB=AC

this means that:

∠B=∠C

Hence,

5x=40

on dividing both side of the equation by 5 we get:

x=8

Hence, we get:

∠B=5x=5×8=40°

i.e. ∠B=40°

Also we know that sum of all the angles of a triangle is 180°.

i.e.

∠A+∠B+∠C=180°

Hence,

2y+20+40+40=180

⇒ 2y+100=180

⇒ 2y=180-100

⇒ 2y=80

On dividing both side of the equation by 2 we obtain:

y=40

Hence, the value of y is:

40

You purchase 26 parking hours that you can use the next month to park your food truck at the fair. Weekday hours park $2 per hou
ICE Princess25 [194]

Answer:

Number of week day hours purchased  is 5

Step-by-step explanation:

Total number of Parking hours purchased = 26 parking hours

Parking cost on weekdays = $2 per hour

Parking costs on weekends = $10 per hour

Total amount spent on parking =  $220.

To Find:

Number of week days purchased = ?

Solution:

Let  

The number of week days purchased be x

The number of weekends purchased be  y

We know that the total hours purchased is 26

So,

x+y = 26

y = 26-x------------------------------------------------------(1)

Now the total cost is 220

(Total number of weekdays X cost per weekday ) +(Total number of weekends + cost per weekend) =220

Substituting the values

=>x\times 2 + y \times 10 = 220

=>x \times 2 + (26-x) \times 10 =220

=>2x + 260 -10x =220

=>260 -8x = 220

=>260 -220 =8x

=>40 = 8x

=>x=\frac{40}{8}

x= 5-------------------------------------------(2)

Now substituting (2) in (1) we get

y= 26-5

y= 21

A rectangle has a length of 80 units and a width of 39 units. Find the length of the diagonal.
levacccp [35]
Equation = a² + b² = c²

a = 80
b = 39
c = Diagonal

a² + b² = c²
80² + 39² = c²
6400 + 1521 = c²
   c² = 7921
   c  = √7921
   c  = 89

 Answer = 89 units
