In the given figure , the value of x is

Answers

Answer 1

Answer: I can see how you might have trouble with this one, because the drawing isn't clear.
Here's what it's trying to show:

-- The line 'a'--'b' is the line where a wall meets the floor.

-- The line to 'c' is a vertical line drawn on the wall.

-- The line to 'd' is a line drawn on the floor.

If you can see it like that, then there are two giveaways for the value of 'x':

One way:
'c' is perpendicular to the floor. That's the only way the angles
on the wall on each side of it ... 3x and 3x ... could be equal, and
they must be 90 degree angles, so 'x' is 30 degrees.

The other way:
The line on the floor, to 'd', is not perpendicular to the wall, because the angles
on the floor on each side of it are not equal. But the two of them do add up to
180 degrees, because the line 'a'--'b' is a straight line.
So 'x' is what's left over when 150 degrees is taken away from 180 degrees.
'x' is 30 degrees again.

Answer 2

Answer: $150+3x+3x+x=360\n 7x=210\n x=30$

A pizza with 2 toppings from Maria's Pizza Place costs $11.00.

A pizza with 5 toppings from Maria's Pizza Place costs $14.75.

Each topping at Maria's Pizza Place costs the same amount.

1. What is the price per topping at Maria's Pizza Place?

2. Write an expression that represents the cost, in dollars, of a pizza at Maria's Pizza Place given the number of toppings (n).

Answers

1.

X - base price
Y - one topping price

You have to create 2 equations:

x + 5y = 14.75 - base amount + 2 toppings give 14.75
X + 2y = 11 - base amount + 2 toppings give $11

You have deduct both equations
X - x = 0
5y - 2y = 3y
14.75 - 11 = 3.75

That means:
3y = 3.75 divide by 3
Y = 1.25

So the price of the topping is $1.25

2.

You have to calculate the base price first:

X + 2*1.25 = 11
X + 2.5 = 11
X = 8.5

Then it is simple:

Price of the pizza = base price + number of toppings multiplied by price of the topping

That means:

Price of the pizza = 8.5 + n * 1.25

Answer:

The box or area method

Step-by-step explanation:

U first set the fraction : 6700/20.

U can cancel out the zeroes, to get 670/2.

Then u basically find half of 670, by doing half of 600 plus half of 70, which is 335

If the ratio of the purple flowers to black flowers is 4 to 8 and there are a total of 108 flowers,how many of the flowers are purple

Answers

Answer: 36

Step-by-step explanation:

Given : The ratio of the purple flowers to black flowers is 4 to 8.

Let the number of purple flowers be 4x and the number of black flowers be 8x.

Since , there are a total of 108 flowers.

Then we have the following equation :-

$4x+8x=108\n\n\Rightarrow\ 12x=108\n\n\Rightarrow\ x=(108)/(12)=9$

Now, the number pf purple flowers = 4(9)=36

Hence, there are 36 purple flowers.

36 flowers would be purple. Here's why:
The ratio 4:8 is the same as 1:2. This means that of every three flows, 1 is purple and 2 are black.
Since 1/3 of the flowers are purple, you'd take 108 x (1/3), or simply divide by 3. Your answer would be 36, and that's how many flowers are purple.
