Please help! And make sure to add a let statement!
Reptile [31]

Answer: See explanation

Step-by-step explanation:

1. Let the small number be x

Then, the bug number will be: x + 25

Therefore, x + x + 25 = 131

2x + 25 = 131

2x = 131 - 25

2x = 106

x = 106 / 2

x = 53

Small number= 53

Big number = x + 25 = 53 + 25 = 78

2. Let the small number be x

Then, the bug number will be: x + 14

x + x + 14 = 58

2x + 14 = 58

2x = 58 - 14

2x = 44

x = 44/2

x = 22

Small number = 22

Bug number = 22 + 14 = 36

The numbers are 22 and 36.

3. Let number of basketball sold be x

Therefore, number of football sold will be x+3.

Therefore, x + x + 3 = 27

2x + 3 = 27

2x = 27 - 3

2x = 24

x = 24/2

x = 12

12 basketball were sold

Number of footballs sold = 12 + 3 = 15

4. Let calories in bowl of soup x

Hamburger = 2 × x = 2x

Therefore, x + 2x = 738

3x = 738

x = 738/3

x = 246

There are 246 calories in bowl of soup

Calories in hamburgers = 246 × 2 = 492 calories

Noah wants to clean his second story windows and plans to buy a ladder that will reach at least
Lina20 [59]

Answer:

Noah should buy a ladder of length greater than <u>28.1 ft</u> to reach at least 22 feet height.

Step-by-step explanation:

Given:

Noah has to reach at least 22 ft height.

Angle made by the base of ladder with the ground = 51.5°

To find the length of the ladder.

Solution:

On drawing the situation, we get a right triangle. The hypotenuse of the triangle represents the length of the ladder.

In triangle ABC.

∠C = 51.5°

AB = 22 ft

Applying trigonometric ratio to find AC (length of the ladder).

\sin\theta = \frac{Opposite\ side}{Hypotenuse}

\sin C=\frac{AB}{AC}

Plugging in values.

\sin 51.5\°=\frac{22}{AC}

Multiplying AC both sides.

AC\sin 51.5\°=\frac{22}{AC}\times AC

AC\sin 51.5\°=22

Dividing both sides by \sin 51.5\°

\frac{AC\sin 51.5\°}{\sin 51.5\°}=\frac{22}{\sin 51.5\°}

AC=\frac{22}{\sin 51.5\°}

AC=28.1\ ft

Thus, Noah should buy a ladder of length greater than 28.1 ft to reach at least 22 feet height.
