Step-by-step explanation:

Answer:

true

Step-by-step explanation:

sinA² + cosA²=1

⇔(1/2)² + cosA²=1

⇔cosA=±(√3/2)

Yes, the triangle is a right triangle.

A triangle is called a right triangle if it has an angle measuring 90°.

Given that in a triangle if Sin A = 1/2 and Cos A = √3/2, then the triangle is a right triangle,

So,

Sin A = 1/2

Sin A = Sin 60°

A = 60°

Also, we know that the sine and cosine of an angle is complementary,

So,

Sin A = Cos (90-A)

Therefore, Cos(90-30)° = Cos 30° = √3/2

Therefore, ABC is a right triangle.

Hence the triangle is a right triangle.

Step-by-step explanation:

48 oranges in 5 minutes means she picked 48 oranges in 300 seconds.

Divide 48 by 300 to get what she would pick in one second.

This equals 0.16

Multiply 0.16 by 120 seconds [how many seconds are in two minutes].

This equals 19.2 oranges in two minutes. As she cannot pick 0.2 of an orange, she could pick 19.

Answer:

V = 249,000(0.929)^t

Step-by-step explanation:

100% - 7.1% = 92.9% = 0.929

0.929 must be raised to t, the number of years.

V = 249,000(0.929)^t

Step-by-step explanation:

Price of 1000 bricks = Rs. 3500

Price of 1 brick = 3500 / 1000

                        = Rs. 3.5

Price of 6000 bricks = Rs. 3.5 * 6000

                                 = Rs. 21000

Hope it will help :)

Step-by-step explanation:

(A) Darius is at least 36 inches tall.

(C) William’s height is less than 68 inches.

(F) Darius is no more than 4 inches taller than twice William’s height.

Step-by-step explanation:

edge2022

The inequality w < 68 can be written as William’s height is less than 68 inches.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, d ≥ 36, w < 68 and d ≤ 4 + 2w.

Atleast means all probabilities larger than the given probability ('at least') Atmost means all probabilities smaller than the given probability ('at most')

Here, d ≥ 36

Darius is at least 36 inches tall.

w < 68

William’s height is less than 68 inches.

d ≤ 4 + 2w

Darius is no more than 4 inches taller than twice William’s height.

Therefore, the inequality w < 68 can be written as William’s height is less than 68 inches.

Step-by-step explanation:

using the Pythagorean theorem  a²+b²=c²

or the two shorter sides square added together equal the longest side squared

5²+12²

5²=25

12²=144

144+25=169

then we just have to take the square root of 169

Answer:

[tex]\Huge\boxed{x=8}[/tex]

Step-by-step explanation:

Hello There!

Remember the sum of all of the angles in a triangle is 180

so we can use this equation to solve for x

180 = 50 + 60 + 8x + 6

now we solve for x

step 1 combine like terms

50 + 60 + 6 = 116

now we have

180=8x+116

step 2 subtract 116 from each side

116 - 116 cancels out

180 - 116  = 64

now we have

8x = 64

step 3 divide each side by 8

8x/8=x

64/8=8

we're left with x = 8

Answer:

(-2,-1)

Step-by-step explanation:

Given

[tex]Q =(-4,1)[/tex]

[tex]R = (-4,4)[/tex]

[tex]S = (2,1)[/tex]

180 degrees rotation

Required

Determine the coordinate point S'

For a 180-degree rotation, the transformation rule is: (x, y) to (-x, -y)

So:

[tex]S = (2,1)[/tex] ==> [tex]S' = (-2,-1)[/tex]

Hence, the coordinate point of S' is (-2,-1)

66°

Step-by-step explanation:

Given that :

Right angle measure of a triangle are used in a design :

A right angles triangle has one of its angle equals 90 ;a

Since the second angle is given as 24 ; b

The measure of the third angle ; c will be :

Sum of angles in a triangle = 180

(a + b + c) = 180

(90 + 24 + c) = 180

c = 180 - 114

c = 66°

Step-by-step explanation:

5x + 20 = 5

Subtract 20 from both sides

5x + 20 - 20 = 5 -20

{If two numbers have different sign, subtract and the result will have the sign of the bigger number. 20 -5 = 15, bigger number is 20, so -15}

              5x  = - 15

Divide both sides by 5

              5x/5 = -15/5

x = - 3
