So if we take x to be one jar of chili, and y to be one jar of salsa, then the equation for Julia's purchase would be 3x + 2y = 10.07. Likewise, the equation for Marcia's purchase would be 2x + 4y = 12.98. The answer you have chosen should be correct, because none of the other options work with the question.

Each side of the square below is 8 inches. A triangle inside of a square. The top of the triangle divides a side of the square i

dmitriy555 [2]

The probability that a point is chosen at random in the square is in the blue region is 0.8.

<h3>What is Probability?</h3>

The probability helps us to know the chances of an event occurring.

$\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

As we know that the area of the shaded region is the sum of the area of triangle A and the area of triangle B. Therefore, the area of the blue shaded region is,

$\text{Area of shaded region} = (\dfrac{1}{2} \times 8 \times 8) + (\dfrac{1}{2} \times 4 \times 8)$

$= (32) + (16)\\\\= 48\rm\ in^2$

The area of the square can be written as,

$\text{Area of Square} = \rm(Side)^2 = 8^2 = 64\ in^2$

Now, the probability that a point is chosen at random in the square is in the blue region can be written as,

$\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\$

$\rm Probability = \dfrac{\text{Area of blue region}}{\text{Area of square}}\\\\Probability = \dfrac{48}{60} = 0.8$

Hence, the probability that a point is chosen at random in the square is in the blue region is 0.8.

What basic trigonometry identity would you use to identify that sin x cos x tan x = 1 - cos^2x

arsen [322]

Answer:

tanx = sinx/cosx

Step-by-step explanation:

Given the expression

sin x cos x tan x = 1 - cos^2x

According to trigonometry identity

tan x = sinx/cosx

Substitute into the expression. From LHS

sin x cos x tan x

= sin x cos x (sinx/cosx)

= sin²x

Also since sin²x+cos²x = 1

Hence sin²x = 1 - cos²x (RHS)

The correct option is therefore tanx = sinx/cosx

dem82 [27]

Answer:

D) 80

Step-by-step explanation:

Your answer is 80 because to find median you must Add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. Which I did and got 80 Your welcome

Hope this helped if it did plz give me brainiest Thanks <3

Find the surface area of the figure using the net shown. The area of the figure is yd2

geniusboy [140]

Answer:

Surface area = 233 yards²

Step-by-step explanation:

The surface area of the figure below is the sum of the area of each faces. This means the total surface area of the figure.

The figure has 4 triangle and 1 rectangle. The surface area will be the sum of area of the rectangle and the area of the 4 triangles.

surface area = base area(rectangle) + 2(area of similar triangle) + 2(area of similar triangle)

Base area

area of the rectangle = length × breadth

area of the rectangle = 16 × 5 = 80 yards²

Area of the 2 similar triangle

area of triangle = 1/2 × base × height

area of triangle = 1/2 × 5 × 5

area of the triangle = 25/2 = 12.5

For the 2 similar triangle = 12.5 × 2 = 25 yard²

Area of the other 2 similar triangle

area of a triangle = 1/2 × base × height

area = 1/2 × 16 × 8 = 128/2 = 64 yards²

For the 2 similar triangle = 64 × 2 = 128 yards²

Surface area = 80 yards² + 25 yard²+ 128 yards² = 233 yards²
