Answer:

B

Step-by-step explanation:

let the price of pizza and soda( per 2 litre bottle) be x and y

from 1st condition

12x+2y=137.6.....(1)

from 2nd condition

x+y =11.95.......(2)

multiply eq. (2) by 2

2x+2y=23.9.....(3)

subtracting (1) and (3)

12x+2y=137.6

2x+2y= 23.9

10x = 113.7

x=113.7/10

x=11.37

2(11.37)+2y=23.9

22.74+2y=23.9

2y=23.9-22.7

2y=1.2

y=0.6

So the prices of  the pizza and soda are 11.37 and 0.6 dollars.

Each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

Let x be the cost of one pizza, and y be the cost of one 2-liter of soda.

According to the information given, we can write the following two equations:

1. For the pizza and soda purchased for the theater party:

12x + 6y = 137.64

2. For the pizza and soda purchased for Katya's family:

1x + 1y = 11.95

Now, we have a system of two equations with two variables. We can solve it to find the values of x and y.

First, let's solve the second equation for y:

y = 11.95 - x

Next, substitute this value of y into the first equation:

12x + 6(11.95 - x) = 137.64

Now, simplify and solve for x:

12x + 71.7 - 6x = 137.64

Combine like terms:

6x + 71.7 = 137.64

Subtract 71.7 from both sides:

6x = 65.94

Finally, divide by 6:

x = 65.94 / 6

x ≈ 10.99

Now that we have the value of x, which is the cost of one pizza, we can find the cost of one 2-liter of soda using the second equation:

y = 11.95 - x

y ≈ 11.95 - 10.99

y ≈ 0.96

So, each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

Answer:

- 7, - 3, 1, 5

Step-by-step explanation:

Using the recursive rule and a₁ = - 7, then

a₂ = a₁ + 4 = - 7 + 4 = - 3

a₃ = a₂ + 4 = - 3 + 4 = 1

a₄ = a₃ + 4 = 1 + 4 = 5

The first four terms are - 7, - 3, 1, 5

Answer:

the value is 0.707

Step-by-step explanation:

The computation is shown below:

Tan (x) = sen (x) ÷ cos (x)

Tan 45° = sen 45° ÷ cos 45° = 1

Now

Sen^2 (x) + cos^2 (x) = 1

Sen^2 (x) + sin^2 (x) = 1 (As sen (x) = u)

2u^2 = 1

u = √1 ÷ √2

= √2 ÷ 2

= 0.707

Hence, the value is 0.707

Answer:

For 2 portions, our Ingredients include

80g of oats, 0.48L of milk and 24g of sugar

Step-by-step explanation:

For 5 portions of ingredients

We need 200g of oats, 1.2L of milk and 60 g of sugar

Hence, for 2 portions of Ingredients, the measure of ingredients is calculated as:

For Oats

5 portions = 200g oats

2 portions = x

Cross Multiply

5x = 2 × 200g

x = 2 × 200g/5

x = 80g of oats

For Milk

5 portions = 1.2L milk

2 portions = x

Cross Multiply

5x = 2 × 1.2L

x = 2 × 1.2L/5

x = 0.48 L of milk

For Sugar

5 portions = 60g of sugar

2 portions = x

Cross Multiply

5x = 2 × 60g

x = 2 × 60g/5

x = 24g of sugar

Therefore for 2 portions, our Ingredients include

80g of oats, 0.48L of milk and 24g of sugar

Step-by-step explanation:

Whole numbers between 20 and 50 will have 10s digits in the range 2–5.

When 4 is added to these numbers, we get ...

  2+4 = 6

  3+4 = 7

  4+4 = 8

  5+4 = 9

When 4 is subtracted from these numbers, we get ...

  2-4 = -2

  3 -4 = -1

  4 -4 = 0

  5 -4 = 1

__

The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...

  26, 37, 40, 48

__

We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.

Lacey need to add 5250 cubic centimeter of water into the fish tank to raise the water level up to the minimum line

Step-by-step explanation:

The bottom dimension of the tank is 75 cm and 35 cm

Water in the tank is 2 cm lower than the minimum line of the tank.

In order to raise the water in tank above the minimum level, we need to add 75 cm * 35 cm * 2 cm

Hence, the total water to be added is

[tex]75 *35 *2 = 5250[/tex] cubic centimeter

Answer:

The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

Brainlist Pls!

Answer:

Step-by-step explanation:

A landscaping company placed two orders with a nursery. Sam tried to use system of equation to solve the problem.

Let us represent

Cost of bushes = x

Cost of trees = y

The first order was for 13 bushes and 4 trees, and totaled $327.50.

Hence

13x + 4y = 327.5......Equation 1

The second order was for 6 bushes and 2 trees, and totaled $142.96.

Combined both Equations

13x + 4y = 327.5......Equation 1

6x + 2y = 142.96 ........ Equation 2

We solve using Elimination method

We Multiply Equation 1 by 2 and Equation 2 by 4 to Eliminate y

26x + 8y = 655 ..... Equation 3

24x + 8y = 571.84 ..... Equation 4

We substract Equation 4 from Equation 3

2x = 83.16

x = 83.16/2

x = $41.58
