Answer:

b = 33

Step-by-step explanation:

y = number of years from now

b = total number of lunch boxes in her collection

b = 1y + 27

b = 1(6) + 27

b = 6 + 27

b = 33

This means by the 6th year, Nancy will have 33 lunch boxes in her collection.

Hope this helps!

Sin(2x+30°)=1 <br> Tìm x <br> Cảm ơn vì giúp đỡ
Pie

Answer:

Step-by-step explanation:

This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):

sin^{-1}[sin(2x+30)]=sin^{-1}(1)

On the left, the inverse sin "undoes" or cancels the sin, leaving us with

2x + 30 = sin⁻¹(1)

The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:

2x + 30 = 90 and

2x = 60 so

x = 30

You're welcome!

Jackson drinks 0.44 liters of water, which was 55% of the water in the bottle. How much water was in the bottle to start?
Delicious77 [7]

Answer:

He had 0.8 liters to start with...

Step-by-step explanation:

0.44 is 55% of what? (what = x)

Equation: Y = P% * X

X = Y/P%

X = 0.44/55%

55% = 0.55

X = 0.44/0.55

X = 0.8

Answer:

The building is 187.5 feet tall.

Step-by-step explanation:

A nearby person is 6 feet tall, and casts a shadow that is 8 feet long.

This means that the relation between the real height and the shadow is given by:

\frac{6}{8} = \frac{3}{4}

A tall building casts a shadow that is 250 feet long. How tall is the building?*

The real height is three fourths of the shadow. So

\frac{3}{4}*250 = 187.5

The building is 187.5 feet tall.
