4/12 = 33%

There are 12 options in total. If you get rid of the tails and numbers 5 and 6, there are 4 options left. So that means 4 out of 12 (4/12). 4/12 in percentage form is 33%.

I hope this helped. Brainliest appreciated.

My favorite recipe for lemonade calls for 4 cups of water to 3/4 cups sugar. How

Nikolay [14]

Answer and Step-by-step explanation:

To find the unit rate, divide the 4 cups of water and the $\frac{3}{4}$ cups sugar by 4 to get a unite rate for 1 cut of water.

4 divided by 4 equals 1.

$\frac{3}{4}$ divided by 4 equals $\frac{3}{16}$ .

Now, we multiply $\frac{3}{16}$ by 6.

$\frac{9}{8}$ is how many cups of sugar that needs to be measured for 6 cups of water.

A) Using theorems pertaining to transverals and parallel lines, prove that m∠1 + m∠2 = 180o

PtichkaEL [24]

A) Two parallel lines, intersecting a 3rd line (a traversal), indicates that two same-sided, internal angles MUST be SUPPLEMENTARY (sum, or add up to 180°).

b) Since <1 and <2 are supplementary, they add up to 180°. Therefore, <1 + <2 = 180:
(20x+5) + (24x-1) = 180
44x + 4 = 180
44x + 4 -4 = 180-4
44x = 176
44x/44 = 176/44
x = 4

The area of a triangle is 15x^4+3x^3+4x^2-x-3 square meters. The length of the base of the triangle is 6x^2-2 meters. What is th

MArishka [77]

Answer:

The height of the triangle is: $H = (5x^2 + x +3)$

Step-by-step explanation:

Here, the area the triangle is given as: $15x^4 + 3x^3 + 4x^2 - x - 3$

Also, base of the triangle = $(6x^2 -2)$

Let us assume the height of the triangle = H units

Now, AREA of TRIANGLE = $\frac{1}{2} \times B \times H$

$\implies (15x^4+3x^3+4x^2-x-3 ) = \frac{1}{2} \times ( 6x^2-2) \times H\\\implies H =\frac{ (15x^4+3x^3+4x^2-x-3 )}{(3x^2-1)}$

Solving by LONG DIVISION, we get:

$H = (5x^2 + x +3)$

Hence, the height of the triangle is: $H = (5x^2 + x +3)$

Jessica wants to give a 20% tip to a taxi driver. If the fare is $23.78, what amount did she tip the driver?

dedylja [7]

You should mulitply. $23.78 * 0.20 = 4.756

Then you add. 4.756 to $23.78 = $28.536

Now you round $28.536 to the hundredths so that you can pay it with coins.

The anwser is $4.76 and the total amount for the taxi ride would be $28.54

A stadium has two sections, A and B.

Alekssandra [29.7K]

ANSWER: a=12 b=15
Explanation: (look at work below)

4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
