Answer: The answer would be t = 5/12

Step-by-step explanation:

1 x 2/3 - t = 1/4
⇒ We need to add fractions.The following rule is applied:This example involves 2 terms.Note that 1 non-fractional terms are treated as fractions with denominator equal to 1. The LCD is equal to:3

2+(-3)t/3 = 1/4

2-3t/3=1/4
-3t+2/3=1/4
⇒ Simple numerical terms are commonly written last.
-3t+2/3=1/2^2
4(-3t+2)=3
-4x3t+4x2=3
⇒ Numerical factors in this term have been multiplied.

-12t+8=3
(-12t+8) + (-8) = 3+(-8)
-12t+8-8=3-8
-12t=-5
12t/12 =5/12
⇒ In order to isolate the variable in this linear equation, we need to get rid of the coefficient that multiplies it.This can be accomplished if both sides are divided by -12 .

Answer: t=5/12

Pavlova-9 [17]

Answer:

3.2%

Step-by-step explanation:

The computation of the annual rate of interest is shown below:

As we know that

Simple interest = Principal × rate of interest × time period

($1,857.60 - $1,800)  = $1,800 × rate of interest × 1

$57.60 = $1,800 × rate of interest × 1

So, the rate  of interest is

= $57.60 ÷ $1,800 × 100

= 3.2%

Hence, the rate of interest on annual basis is 3.2%

Answer:

Y=168

Step-by-step explanation:

Y varies directly as X

Y=kx

K is a constant

28=k2

K=28/2 =14

Y=14x

Y=14×12

2c+17.6 =6 SOLVE --------------- 4 give your answer as a decimal get brainly
scZoUnD [109]

Answer:

\huge\boxed{x = -5.8}

Step-by-step explanation:

2x + 17.6 = 6

Subtracting both sides by 17.6

2x = 6 - 17.6

2x = -11.6

Dividing both sides by 2

x = -11.6 / 2

x = -5.8

Find values of sine cosine tangent for
slava [35]

Answer:

The correct answer is option a

Sin A = 2√13/13

Cos A  = 3√13/13

Tan A = 2/3

Step-by-step explanation:

From the figure we can see that,a right angled triangle.

ΔABC

<u>To find side AB </u>

AB = √(AC)² + (BC)² =√(36² - 24² )= √1872

AC = 12√13

<u> To find the trigonometric ratio </u>

Sin A = BC/AB = 24/12√13  = 2√13/13

Cos A = AC/AB = 36/ 12√13  = 3√13/13

Tan A = BC/AC = 24/36 = 2/3

lisov135 [29]

Answer:

200√3

Step-by-step explanation:

The triangle given here is a special right triangle, one with angles measuring 30-60-90 degrees. The rule for triangles like these are that the side opposite the 30° angle can be considered x, and the side opposite the 60° angle is x√3, while the hypotenuse, or side opposite the right angle, is 2x. All we need to know here are the two legs to find the area.

Since b is opposite the 30° angle, it is x, while side RS is opposite the 60° angle, meaning it is equal to x√3, meaning that the area of the triangle is 1/2*x*x√3. We can substitute in 20 for x, making our area 1/2*20*20√3. Multiplying we get 10*20√3, or 200√3.
