Find the angles of x and y

Gnesinka [82]

or, x=180

or,34=180

or,180-34

or x=146

Now,

or, y=146

or,18=146

or146-18

or, y=128

there is x is 34 and its all side angle is 180 degree So put x =180 and then put x value is 34 =180 and there is no values in front of 34 so there will be + and if +so in another side it will be - and then after put 180-34=146

sveticcg [70]

Answer:

33

Step-by-step explanation:

Given that :

Card numbered from: 500 - 799

The required number of values must meet both conditions 1 and 2

Condition 1 : first of the 3 digits is odd :

500 - 599 = 100

700 - 799 = 100

(100 + 100) = 200 cards

Condition 2: three digits is divisible by 6

{500 - 599} and {700 - 799}

The numbers divisible by 6 are 33

WRITE AN ALGEBRAIC EXPRESSION TO MODEL THE GIVEN CONTEXT. GIVE YOUR ANSWER IN SIMPLEST FORM. The original price of an item le

quester [9]

Answer:

The original price of an item less a discount of 20% is 0.8p where p is the original price

Step-by-step explanation:

Here, we want to write an algebraic expression that represents the original price of an item less a discount of 20%

Let the original price of the item be p

The meaning of the ‘less’ is that we are subtracting 20% of the price from the original price ;

So 20% of the price will be 20/100 * p = 20p/100 = p/5 = 0.2p

So let’s take this away from the original price p

That will be;

p - 0.2p = p(1-0.2) = 0.8p

Calculate percentage to the nearest 0.1%.

Anna71 [15]

9514 1404 393

Answer:

a. $4.17

b. 233.3%

Step-by-step explanation:

a. The proportion the markup (m) is to the total (t) is ...

m : t = 7 : 10

The total is the cost (c) plus the markup, so we have ...

m : t = 7 : 10 = m : (m +c) = 7 : 7 +3

Then the ratio of total price to cost is ...

t : c = 10 : 3

The menu price of the pie slice will be ...

$1.25 × 7/3 ≈ $4.17

__

b. The ratio of markup to cost is ...

m : c = 7 : 3 ≈ 2.333 = 233.3%

WILL MARK BRAINLIEST PLEASE HELP ME

Answer:

4 blue marbles

Skills needed: Number Theory, Fractions

Step-by-step explanation:

1) The problem tells us that the jar contains marbles that are either red, green, or blue (No Other Color).

It also mentions that $\frac{2}{5} (\frac{4}{10})$ of the marbles are red

and that $\frac{1}{10}$ of the marbles are blue

- The given statement is that 20 marbles are green, and we need to find out the number of blue marbles.

2) We need to first find out the total number of marbles, and then multiply that by $\frac{1}{10}$ to get the # of blue marbles.

---> Given $\frac{4}{10}$ are red and $\frac{1}{10}$ are blue, $1-\frac{1}{10}-\frac{4}{10}$ of the marbles are green (since fractions add up to 1 whole)
