The weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles was 3:4

Let 3x and 4x are the seeds from the smaller and bigger pile.

= 4x + 2  (greedy hamster placed another 2 pounds of seeds in the bigger pile)

= 3x - 1/4 (ate 1/4 pound from the smaller pile)

4x + 2 = 5x

Because the quantities of seeds in those piles is in the ratio of 5:16

After solving:

x = 2

Smaller pile weight = 3x = 3(2) = 6

Bigger pile wieght = 4x = 4(2) = 8

Thus, the weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

The compound amount and the interest earned are $13,222.17 and $2,222.17 respectively.

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

We know the formula for continuous compounding:

[tex]\rm A = P(e)^{rt}[/tex]

[tex]\rm A = 11000(e)^{0.023\times8}[/tex]

A = $13,222.17

I = A - P = 13,222.17 - 11000

I  = $2,222.17

Thus, the compound amount and the interest earned are $13,222.17 and $2,222.17 respectively.

a. The exact value of cosθ = -5/√74

b. The exact value of secθ = -√74/5

c. The exact value of cotθ = 5/7

Since the terminal side of the θ is the point, (-5, -7), we need to find the length of the terminal side.

So, r = √(x² + y²) where

So, r = √(x² + y²)

r = √((-5)² + (-7)²)

r = √(25 + 49)

r = √74

Since the trigonometric ratio cosθ = x/r

Substituting the values of x and r into the equation, we have

cosθ = x/r

cosθ = -5/√74

So, the exact value of cosθ = -5/√74

Since the trigonometric ratio, secθ = r/x

Substituting the values of x and r into the equation, we have

secθ = r/x

secθ = √74/-5

secθ = -√74/5

So,  the exact value of secθ = -√74/5

Since the trigonometric ratio cotθ = x/y

Substituting the values of x and y into the equation, we have

cotθ = x/y

cotθ = -5/-7

cotθ = 5/7

The final displacement is 2cm in the right.

Given that the object begins from 0 and moves 3 cm towards the left side and then, 5 cm towards the right side.

The displacement is known as shortest distance between the initial and final positions.

Let the x-axis be the positive, +ve, and on the right side and negative -ve on the left side.

Thus, displacement would be:

D= 0 -3 +5

D= 2 cm

This implies that the object displaces 2cm towards the right side

Hence, the final displacement when object moves from 0 and 3 cm to the left and then 5 cm to the right is 2cm in the right side.

Answer: x < 3

Step-by-step explanation:

      To solve this inequality, we will simplify and isolate the x variable.

   Given:

5x - 4 < 2x + 5

   Add 4 to both sides:

5x < 2x + 9

   Subtract 2x from both sides:

3x< + 9

   Divide both sides by 3:

x < 3

Answer:

x < 3

Step-by-step explanation:

Well you want to isolate x so start by subtracting 2x from both equations that way you remove it from the right side and it's only on the left side.

subtract 2x from both equations

[tex]3x-4 < 5[/tex]

add 4 to both equations

An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Given:

Yasmin purchased 6 heads of cabbage that each weighed 2 and  3/8 pounds.

So,

2 and 3/8 = 19/8

1 cabbage = 19/8 pounds

6 cabbages = x pounds

1 * x = 6 * 19/8

x = 114/8

The slope and the y-intercept of the function are: A. Slope = -2/5; y-intercept = -1/3.

Slope (m) = change in y / change in x.

Using two pairs of points form the table value, (1/4, -13/30) and (2/3, -3/5)"

Slope (m) = (-13/30 - (-3/5))/(1/4 - 2/3)

Slope (m) = (-13/30 + 3/5))/(1/4 - 2/3)

Slope (m) = (1/6)/(-5/12)

Slope (m) = (1/6)(12/-5) = 12/-30

Slope (m) = -2/5

Plug in m = -2/5 and (x, y) = (2/3, -3/5) into y = mx + b to find the y-intercept (b).

-3/5 = -2/5(2/3) + b

-3/5 = -4/15 + b

-3/5 + 4/15 = b

The total amount of the drink is 2L. Strawberry concentrate will be X amount, and lemon concentrate will be the other part which is 2 - X.

---Note that we can only use one variable because there is only one equation to be set up here. That's why "the other part" is simply the total amount minus the strawberry amount.

0.4(2) = 0.3(x) + 0.55(2 - x)

---0.4, 0.3 and 0.55 are the decimal equivalents of 40%, 30% and 55%

0.8 = 0.3x + 1.1 - 0.55x

0.8 = -0.25x + 1.1

-0.3 = -0.25x

x = 1.2

Therefore, Chris should use 1.2L of strawberry concentrate and 0.8L of lemon concentrate to get 2L of a 40% concentrate mixture.
