Answer:

Step-by-step explanation:

Givens

Let the number in the Spanish Class = x

Then the number in the Geometry Class = (4/5) x

Equation

x + (4/5)x < 54

Solution

x + (4/5)x < 54

4/5 = 0.8

x + 0.8x < 54

1.8x < 54 Divide both sides by 1.8

1.8x / 1.8 < 54/1.8

x < 30

The sign used in the equation is less than, not less than or equal to.

The number of students taking Spanish cannot equal 30. There must be 29 in the Spanish Class.

Answer:

1a. 0.5291

1b. 2.0370

1c. 4.2661

2a. 25.7693

2b. 1.8665

2c. 24.0420

2d. 5

Step-by-step explanation:

sin(34) = 0.5290826861 ≈ 0.5291

12 tan(63) = 2.036997025 ≈ 2.0370

5 cos(56) = 4.2661005386 ≈ 4.2661

2a. You have to use tan because tan is opposite over adjacent.

You have $tan(x)=\frac{14}{29}$

You have to use inverse tangent.

$tan^{-1}(\frac{14}{29})=25.76932762 = 25.7693$

2b. You have to use cos because cos is adjacent over hypotenuse.

You have $cos(39)=\frac{x}{7}$

0.2666429324 = $\frac{x}{7}$

x = 1.8665005268 ≈ 1.8665

2c. You have to use sin because sin is opposite over hypotenuse.

$sin(x) = \frac{11}{27}$

$sin^{-1}(\frac{11}{27})=24.04207591=24.0420$

2d. Use the pythagorean theorem.

24x=15x×3 plz answer this

Ira Lisetskai [31]

The answer is x=3.

Subtract 15x from 24x which makes:
9x=3

Divide 9 by 3 which makes 3.

Evan and Carter are making chocolate milk which mixes milk with chocolate syrup. Evan's recipe calls for 5 cups of milk for ever

Alex73 [517]

Answer:

Evan's recipe

Step-by-step explanation:

Given that:

Evan's recipe :

5 cups of milk for every 4 teaspoons of chocolate syrup

Carter's recipe:

3 cups of milk for every 2 teaspoons of chocolate syrup.

Recipe with the stronger tasting chocolate milk:

Take the ratio of cups of milk to teaspoons of chocolate syrup:

Evan's :

5 / 4 = 1.25

Carter's :

3 /2 = 1.5

Evan's recipe has the stronger tasting chocolate milk recipe :

5 milk cup = 4 chocolate spoons

Number of chocolate milks for 3 milk cups = x in Evan's recipe

5 = 4

3 = x

5x = 12

x = 12/5

x = 2.4 teaspoons

This is 2.4 spoons compared Carter's recipe which uses 2 spoons for every 3 milk cups
