I did the test and got a 100%

Answer:

8 chicken, 4 beef

Step-by-step explanation:

No. of chicken: x

No. of beef: y

x + y = 12

x = 12 - y

10x + 14y = 136

10(12 - y) + 14y = 136

120 - 10y + 14y = 136

4y = 16

y = 4

x = 12 - 4

x = 8

Answer:

w=5

Step-by-step explanation:

the triangle has the same size of area as the side of the rectangle so therefore 5

Answer:

The area of a triangle is [tex]A\Delta=\frac{1}{2}(base)(height)[/tex]

So, the area of the given triangle is:

[tex]A\Delta=\frac{1}{2}(5)(6)\\A\Delta=\frac{1}{2}(30)\\A\Delta=15cm^2[/tex]

The area of a rectangle is

[tex]A=(length)(width)\\A=(6)w\\A=6wcm^2[/tex]

Once the area of both are the same:

[tex]6w=15\\w=\frac{15}{6} \\w=2.5cm[/tex]

Answer:

52.5 lbs

Step-by-step explanation:

We can use a ratio to solve

30 ft              75 ft

-------------- = ------------

21 lbs              x lbs

Using cross products

30x = 75*21

30x = 1575

Divide each side by 30

30x/30 =1575/30

x =52.5 lbs

Answer:

32.60/100*15 = $4.89 = 15%

Step-by-step explanation:

Answer:

$4.89

Step-by-step explanation:

To find the tip, multiply the tip rate by the price of the bill

tip rate * bill

15% * 32.60

Convert 15% to a decimal by dividing by 100, or moving the decimal 2 spaces to the left

15%/100=0.15

15.0 -->0.15

Substitute the decimal in for the percent and multiply

0.15* 32.60=4.89

So, a 15% tip on $32.60 is $4.89

Answer:

A) 65.87

Answer:

Perpendicular

Step-by-step explanation:

Parallel lines have equal slopes.

The product of perpendicular slopes = - 1

Calculate the slopes of u and v using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 51, 65) and (x₂, y₂ ) = (- 46, 96)

m = [tex]\frac{96-65}{-46+51}[/tex] = [tex]\frac{31}{5}[/tex]

Repeat with (x₁, y₁ ) = (- 37, 85) and (x₂, y₂ ) = (- 6, 80)

m = [tex]\frac{80-85}{-6+37}[/tex] = - [tex]\frac{5}{31}[/tex]

Since [tex]\frac{31}{5}[/tex] × - [tex]\frac{5}{31}[/tex] = - 1

Then the lines are Perpendicular

Answer:

Sin A = 1/2 means taking the inverse of Sin which is arcsin and then solving for A.

Do the same thing for Cos A = 1/2. The inverse of Cos is arccos and then solve for A.

The answer is pi/3. Knowing the unit circle helps too.

Good luck!

If sin A is 1/2. Then the value of cos A will be √3 / 2.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

If sin A is 1/2. Then the value of cos A will be

We know that

sin² A + cos² A = 1

Then we have

(1/2)² + cos²A = 1

cos² A = 1 - 1/4

cos² A = 3/4

cos A = √(3/4)

cos A = √3 / 2

Answer:

2/60

Step-by-step explanation:

Answer:

3i + 2j

Step-by-step explanation:

Acceleration = change in velocity/time

Change in velocity

(14i + j) - (2i - 7j)

= 12i + 8j

Divide by time (t = 4)

3i + 2j

The acceleration of the drone in terms of i and j is 3i+2j.

Acceleration is the amount by which the velocity of something changes over a set period of time.

The formula to find the acceleration is a=(v-v₀)/t, where a=average acceleration, v=final velocity, v₀=initial velocity and t=time.

Given that, a drone is flown, with constant acceleration, in a horizontal plane. When initially observed, at a point P, it has a velocity of (2i-7j) ms⁻¹.

Four seconds later the drone is at a point Q and has a velocity of (14i+j) ms⁻¹.

Acceleration = change in velocity/time

Change in velocity

(14i + j) - (2i - 7j)

= 12i + 8j

Divide by time (t = 4)

= 4(3i+2j)/4

= 3i+2j

Therefore, the acceleration of the drone in terms of i and j is 3i+2j.

Step-by-step explanation:

The only solution to the equation |x+1|+|x-2|=3 is x=2. To find this, we broke the problem into cases based on the nature of absolute values and verified the solution by substitution.

To solve the equation |x+1|+|x-2|=3, we need to consider the different cases due to the absolute value functions.

If x = 2, both x+1 and x-2 are non-negative, and our equation simplifies to x+1+x-2=3, which results in x=2.

If -1 \\leq x < 2, x+1 is non-negative, and x-2 is negative, so the equation becomes x+1-(x-2)=3, which is an identity and does not yield a solution.

If x < -1, both x+1 and x-2 are negative, so the equation becomes -(x+1)-(-x+2)=3, simplifying down to -1=3, which is false and cannot be a solution.

Therefore, the only solution is x=2. We can verify this by substituting back into the original equation. This is consistent with the properties of absolute value equations. Always verify your solutions to ensure they hold in the original equation.

Answer:

[tex]\frac{25}{7}[/tex]

Step-by-step explanation:

Given:

1 gallon = 4.5 liters

Question asked:

What fraction of 150 gallons is 189 liters ?

Solution:

First of all we will convert gallons to liters:-

1 gallon = 4.5 liters

150 gallons = 4.5 [tex]\times[/tex] 150 = 675 liters

Now, to know the fraction :-

675 gallons [tex]\div[/tex] 189 liters

[tex]=\frac{675}{189} \\ \\ Dividng\ both\ numerator\ and\ denominator\ by\ 9\\ \\ =\frac{75}{21} \\ \\ Dividng\ both\ numerator\ and\ denominator\ by\ 3\\ \\ =\frac{25}{7}[/tex]

Therefore, 150 gallons (675 liters)  is [tex]\frac{25}{7}[/tex] of 189 liters.

Option D, f(x) = 3(2)^x, represents an exponential function.

The equation that represents an exponential function is f(x) = 3(2)x. The exponential function has the form y = ab^x, where a and b are constants, and b is greater than 0 and not equal to 1. In this equation, b is equal to 2, which satisfies the condition. Therefore, option D, f(x) = 3(2)x, represents an exponential function.

Mr. Peterson has traveled approximately 376.8 feet after making one full rotation in a lazy river with a diameter of 120 feet, by calculating the circumference of the circle using the formula C = πd.

The question asks how many feet Mr. Peterson has traveled after making one full rotation in a lazy river shaped like a circle with a diameter of 120 ft. To find the distance traveled, we need to calculate the circumference of the circle, which is the total distance around the circle.

The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter of the circle. Using π approximately equal to 3.14 and the given diameter of 120 feet, we calculate the circumference as follows:

C = πd = 3.14 × 120 ft = 376.8 ft

Therefore, Mr. Peterson has traveled approximately 376.8 feet after making one full rotation around the lazy river.
