Answer:

y = -0.525

Step-by-step explanation:

2.2y - y + 7.3 / 10 = 0.1

1.2y + 0.73 = 0.1

1.2y = -0.63

y = -0.525

Answer:

your answer is 1

Step-by-step explanation:

1. 2.2y-(y-7.3)÷10=0.1

2. 2.2y- y-7.3÷10= 0.1

3. 2.2y- y-7.3÷10 · 10= 0.1 ·10

4. 2.2y·10- y-7.3÷10 · 10

simplify: 22y - (y-7.3)= 1

Answer:

4 + 2.5c = 16

Step-by-step explanation:

Let c = number of candy bars

All soda cost $4.00

Each candy bar costs $2.50, so c number of candy bars cost 2.5c.

The total cost is the sum of the costs of the soda and candy bars.

Total cost is 4 + 2.5c

To write the equation we set the total cost expression above equal to the given total cost.

4 + 2.5c = 16

A 22-ft ladder leans against a building so that the angle between the ground and the ladder is 64°. How high does the ladder rea

vodka [1.7K]

The height of the ladder on the building is 19.77 feet

<h3>How high does the ladder reach on the building?</h3>

Represent the height of the ladder on the building with h

So, the given parameters are:

Angle, x = 64 degrees

Length of ladder, l = 22 feet

The height of the ladder on the building is calculated using

sin(x) = h/l

Substitute the known values in the above equation

sin(64) = h/22

Multiply both sides by 22

h = 22 * sin(64)

Evaluate the product

h = 19.77

Hence, the height of the ladder on the building is 19.77 feet
