Answer 1
Answer:

Answer:

cos B = 9/41

Step-by-step explanation:

Using trig functions, since we have a right angle,

cos theta = adjacent side/ hypotenuse

Cos B = 18/82

Dividing the right side by 2

cos B = 9/41
Answer 2
Answer: The answer is A
You have to use the trigonometric ratio as it is a right angle triangle.

Answer:

52.48

Step-by-step explanation:

find the cross sectional area which is the triangle

triangle = 1/2 x 8.2 x 6.4 = 26.24

then, use the area to multiply by the extended length of 2

26.24 x 2 = 52.48

Answer:

use distance formula and solve it

Step-by-step explanation:

this formula is in co ordinate geometry class 10 ncert book

Answer:

5 sqrt(10) square units

Step-by-step explanation:

The coordinates of the points A, B, and C are (-6,-2), (2,-8), and (-4,-6), respectively.

To find the area of a triangle, we can use the following formula:

Area of a triangle = 1/2 * base * height

We can use the distance formula to find the length of the base, which is AB:

d(A,B) = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Substituting the coordinates of A and B, we get:

d(A,B) = sqrt((2 - (-6))^2 + (-8 - (-2))^2) = sqrt(64 + 36) = 10

Now, we need to find the height of the triangle. The height of a triangle is the perpendicular distance from a vertex to the opposite base. In this case, we can draw a perpendicular line from C to AB:

[Image of triangle ABC with line segment CD drawn perpendicular to AB]

The length of CD is the height of the triangle. We can use the distance formula to find the length of CD:

d(C,D) = sqrt(((-7) - (-4))^2 + (-5) - (-6))^2) = sqrt(9 + 1) = sqrt(10) \n

Now, we can find the area of the triangle:

Area of triangle ABC = 1/2 * base * height = 1/2 * 10 * sqrt(10) = 5 * sqrt(10)

Therefore, the area of triangle ABC is 5 square roots of 10 square units.

1.5 - 0.25(a + 4)= 3 + 3(0.05 - 0.5a)

Answers

the answer should be 2.12 
Ok HI again but the answer should be -0.68 the steps are below!    Simplifying 5 + -0.25(a + 4) = 3 + 3(0.05 + -0.5a) Reorder the terms: 5 + -0.25(4 + a) = 3 + 3(0.05 + -0.5a) 5 + (4 * -0.25 + a * -0.25) = 3 + 3(0.05 + -0.5a) 5 + (-1 + -0.25a) = 3 + 3(0.05 + -0.5a) Combine like terms: 5 + -1 = 4 4 + -0.25a = 3 + 3(0.05 + -0.5a) 4 + -0.25a = 3 + (0.05 * 3 + -0.5a * 3) 4 + -0.25a = 3 + (0.15 + -1.5a) Combine like terms: 3 + 0.15 = 3.15 4 + -0.25a = 3.15 + -1.5a Solving 4 + -0.25a = 3.15 + -1.5a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.5a' to each side of the equation. 4 + -0.25a + 1.5a = 3.15 + -1.5a + 1.5a Combine like terms: -0.25a + 1.5a = 1.25a 4 + 1.25a = 3.15 + -1.5a + 1.5a Combine like terms: -1.5a + 1.5a = 0.0 4 + 1.25a = 3.15 + 0.0 4 + 1.25a = 3.15 Add '-4' to each side of the equation. 4 + -4 + 1.25a = 3.15 + -4 Combine like terms: 4 + -4 = 0 0 + 1.25a = 3.15 + -4 1.25a = 3.15 + -4 Combine like terms: 3.15 + -4 = -0.85 1.25a = -0.85 Divide each side by '1.25'. a = -0.68 Simplifying a = -0.68

Earlier this year in a drug bust in Shanghi, China, police seized 2.4 tons of methamphetamines. If a typical dosage is 50mg, how many doses is that bust, which the Chinese police prevented from being sold to the public?

Answers

2.4 tons=2.4 tons*(1,000 Kg / 1ton)*(1,000,000 mg / 1 kg)=
=2,400,000,000 mg=2.4 x 10⁹ mg

Now, we solve this problem by the rule of three.

50 mg ---------------------1dose
2.4x10⁹ mg----------------    x

x=(2.4 x 10⁹ mg * 1 dose) / 50 mg=48,000,000 doses.

Answer: 48,000,000 doses
