a. What is the cost per ounce for the 10-ounce packages of cashews?




b. What is the cost per ounce for the 16-ounce packages of cashews?




c. Which package is the better buy?

Answer:

base :6 units

height:4units

area of a triangle: 1/2 ×b×h

1/2× 6×4=12

12sqaure units should be the area

Step-by-step explanation:

you don't know the Pythagoras formula yet ?

this is something you need to remember for life. this you will encounter everywhere (not just in school) :

c² = a² + b²

in a right-angled triangle c is the Hypotenuse (the side opposite of the 90° angle). a and b are the legs of the triangle.

4.

the legs of this right-angled triangle are the pole and the ground distance to the cable fixture on the ground.

the cable itself is the Hypotenuse (as the right angle is the angle between the pole and the ground distance).

so,

cable² = 8² + 6² = 64 + 36 = 100

cable = sqrt(100) = 10 m

5.

here we have a right-angled triangle with the direct distance between the points being the Hypotenuse, and the x and y coordinate differences are the legs.

so, we have

distance² = (3 - -3)² + (0 - -1)² = 6² + 1² = 36 + 1 = 37

distance = sqrt(37)

please note that since we are squaring, the direction of the differences and their signs do not matter. the square will turn positive and negative distances into positive numbers.

The shaded section is the difference of sector OAB and triangle OAC.

Use Pythagorean

Given that ∠1 and ∠2 are supplementary, the measure of ∠1 is 79 degree.

Hence, option D)79° is the correct answer.

Supplementary angles refer to the pair of angles that sum up to 180 degree.

Given the data in the question;

Since ∠1 and ∠2 supplementary angles, they will  sum up to 180 degree.

∠1 + ∠2 = 180°

(2y + 9) + (3y - 4) = 180

Solve for y

2y + 9 + 3y - 4 = 180

5y + 5 = 180

5y = 180 - 5

5y = 175

y = 175/5

y = 35

Hence, the measure of ∠1 will be;

∠1 = 2y + 9

∠1 = 2(35) + 9

∠1 = 70 + 9

∠1 = 79°

Given that ∠1 and ∠2 are supplementary, the measure of ∠1 is 79 degree.

Hence, option D)79° is the correct answer.

The expressions that can be used to determine the area of the rectangle are:

12 x 7

7 . 10 + 7 . 2

The expressions that can be used to determine the perimeter of the rectangle are:

2 x (12 + 7)

7 + 12 + 7 + 12

2 . 7 + 2 . 12

The expression that cannot be used to find either the area or the perimeter of a rectangle is: 7 + 12

A rectangle is a 2-dimensional quadrilateral with four right angles that sum up to 360 degrees. A rectangle has two diagonals which bisect each other at right angles.

The area of a rectangle is the product of the width and the length.

Area of a rectangle = length x width

12 x 7 = 84 units²

7 . 10 + 7 . 2

70 + 14 = 84

The perimeter of a rectangle is the distance round the rectangle.

Perimeter of a rectangle = 2 x (length + width)

2 x (12 + 7)

2 x 19 = 38 units

7 + 12 + 7 + 12 = 38

2 . 7 + 2 . 12

The distance the slower and faster car travelled are 360 km and 432 km respectively.

Two cars start at the same time from two towns 792 kilometres apart and meet in 9 hours.

One car can travel 8 km faster than the other car.

let

x = speed of the slower car

x + 8 = speed of the faster car

The cars meet in 9 hours and both cover a distance of 792 km.

Therefore,

speed = distance / time

distance = time × speed

Hence,

9x + 9(x + 8) = 792

9x + 9x + 72 = 792

18x = 792 - 72

18x = 720

divide both sides by 18

x = 720 / 18

x = 40

Therefore,

speed of the slower car = 40 km per hour

speed of the faster car = 48 km per hour

Hence,

how far the slower car go(distance) = 40 × 9 = 360 km

how far the faster car go(distance) = 48 × 9 = 432 km

The value of the expression (g ₀ f) (1/2) is 15/4

In this question, we have been given two functions f(x) = x² + 1 and             g(x) = 3x.

We need to evaluate an expression. (g ₀ f) (1/2)

We know that the composite function is a function where the output of one function becomes the input of another function.

First we find the composite function (g ₀ f) (x)

(g ₀ f) (x)

= g(f(x))

= 3(f(x))

= 3 (x² + 1 )

= 3x² + 3

So, (g ₀ f) (x) = 3x² + 3

Now, we find the value (g ₀ f) (1/2)

(g ₀ f) (1/2)

= 3(1/2)² + 3

= 3(1/4) + 3

= 3/4 + 3

The simplification of the expression 3(x + 3y) - 5(x -y) is  -2x + 14y.

According to the given question.

We have an expression

3(x + 3y) -5(x -y)

As we know that, the simplification of an expression means to write an equivalent expression which contains no similar terms.

Therefore, the simplificantion of the expression  3(x + 3y) - 5(x -y) is given by

3(x + 3y) - 5(x -y)

= 3x + 9y - 5x + 5y     (by distributive rule)
