Answer:

5.25

Step-by-step explanation:

If CD is perpendicular to AB, a right angle is formed by the perpendicular lines at the base of the triangle. If we know that AB is 3 we can divided that by two to use half the triangle and create a right trianle with a base of 1.5 (half of 3) a height of rad 3 now all we have to do is use P-Thags to find AC which is the hypotenuse. After doing 1.5 squared + rad 3 squared = ac squared you will get the answer of AC = 5.25

Answer:

√(21) / 2

Step-by-step explanation:

The vertical line divides triangle ABC into two right angles which are congruent.

DB has length AB/2, which comes out to 3/2.  Regard DB as the base of one of the two right triangles.  If the height, CD, is √3, then by the Pythagorean Theorem |AC|² = (3/2)² + (√3)².

Thus, |AC| = √( (9/4) + 3 ), or  √( (9 + 12)/4 ), or √(21) / 2

Kiran is spending $12 on games and rides at another carnival, where a game
Alinara [238K]

Answer:

0.25x + y = 12

Step-by-step explanation:

Given

Kiran is spending $12 on games

it means that he can spend total of $12 on rides and games

number of games is represented by x

cost of 1 game = $0.25

cost of x games = $0.25*x = $0.25x

number of rides is represented by y

cost of 1 rides = $1

cost of x rides = $1*y = $y

Total cost for x games and y rides =cost of x games  + cost of y rides

Total cost for x games and y rides =  $0.25x + $y

given that Kiran is spending $12 on games

Total cost for x games and y rides will be $12

thus,

$12 = $0.25x + $y

removing dollar sign for equation formation

0.25x + y = 12

given above is the equation to represent the relationship between the dollar

amount Kiran is spending and the number of games, x, and the number of

rides, y.

PLEASE HELP it should be easy for someone but I can’t do it
-Dominant- [34]

Answer:

Total crackers on the plate are 12

Step-by-step explanation:

Manuel ate crackers = \frac{1}{3}

His brother ate crackers = \frac{1}{4}

Crackers left on the plate = 5

We need to find how many crackers were there on the plate.

Let x be the total crackers on the plate

So, we can write the equation

x-\frac{1}{3}x-\frac{1}{4}x=5

Because 1/3 and 1/4 crackers are eaten and 5 are left so, we subtract 1/3x and 1/4x from x and equal it to 5

\frac{12x-4x-3x}{12}=5\\\frac{12x-7x}{12}=5\\\frac{5x}{12}=5\\x=\frac{5*12}{5}\\x=12

So, we get x = 12

Therefore, total crackers on the plate are 12

mr. Yoshikawa has 75 papers he graded 60 of them and his student graded the rest. how do you show what percent each graded
Maurinko [17]
If you want to know what percent did Mr. Yoshikawa graded you can say:
60/75 = ?/100 so ? is: 
60*100/75 = 80 % so he graded 80% of the papers and the rest of the papers was graded by his student so: 
100% - 80% = 20% so his student graded 20% of the papers :)))
i hope this is helpful
