Answer:

7.9 ft

Step-by-step explanation:

The hypotenuse is the side opposite of the right angle, hence the hypotenuse for this triangle is 11 ft.

Side $x$ is adjacent to the angle given. So we need adjacent and we have hypotenuse. Which trigonometric ratio relates adjacent and hypotenuse? It is COSINE.

Thus, we can write:

$cos(A)=\frac{adjacent}{hypotenuse}\\cos(44)=\frac{x}{11}$

Cross multiplying, we can solve for $x$ :

$cos(44)=\frac{x}{11}\\x=cos(44)*11\\x=7.91$

Rounding to nearest tenth, we have $x=7.9$ ft.

A rectangular tank is 100 cm long, 30 cm wide and 12 cm deep. What is the estimated capacity of the tank half full? Hint: 1000 c

Licemer1 [7]

To figure this out, you need to multiply all the dimensions together. 100x30=. 3,000cm and 3,000x12= 36,000 cubic centimeters. So now you can divide the 36,000 by 1000 to get the amount of liters the entire tank can hold. 36,000/1000= 36 liters. And because you want to know how much half of the tank is, you divide 36 by 2 and get 18 liters

Erin planted t tomato plants. Leo planted 5 fewer tomato plants than Erin. Filipe planted 10 fewer tomato plants than Erin. Drag

Setler [38]

Answer:

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Explanation:

We are given that:

Erin planted t tomato plants

Leo planted 5 fewer tomato plants than Erin, this means that:

Leo planted = t - 5 tomato plants

Fillip planted 10 fewer tomato plants than Erin, this means that:

Fillip planted = t - 10 tomato plants

Now, we want to find the total number of tomato plants

This means that we will add the number of plants planted by Erin, Leo and Fillip

Therefore:

Total number of plants = t + t - 5 + t - 10

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Hope this helps :)
