5 0

Answer:

\boxed{u = 6.0}

Step-by-step explanation:

Using the cosine rule

c^2= a^2+b^2-2abCosC

Here c = u , a = 11 , b = 12 and C = 30

u^2 = 11^2+12^2-2(11)(12)\ Cos 30\\u^2 = 121+144-2(132)(0.866)\\u^2 = 265-228.6\\u^2 = 36.37

Taking sqrt on both sides

u = 6.0   (To nearest tenth)

A taco stand sells tacos for $3.25 each the stands expenses for the day are $210. define your variables and write an inequality
iogann1982 [59]
If we're going to use an inequality to solve this, then we'd probably be saying that 3.25 x ? >210. The 3.25 is the selling price per taco and the ? is the number of tacos that you sell. According to the equation, the number of tacos times the selling price has to be greater than 210, which are the expenses, in order to gain a profit. If we solve this, we simply divide 210 by 3.25. We will get an answer of 65. So we can conclude that if the taco business wants to have a profit, then they have to sell more than 65 tacos so that they can be able to cover their expenses.

One of the students wanted to know the material in the four propeller
Lyrx [107]

The material is made of carbon composite since the density of this material is similar to the drone

<h3>What is density?</h3>

Density is mass per unit volume. It is is an important property of a material that helps in saying other features of the material. It also says substance that has more weight as a highly dense substance will have more weight when compared with a less dense substance.

<u>Given data</u>

Initial volume of water = 1000ml

the drone displaced the water to 2290 ml

mass of the drone = 2 kg = 2000 g

<h3>Density of the drone</h3>

volume of the drone equals the volume of water displaced

2290 ml - 1000 ml = 1290 ml

density in g/cm*3

= mass / volume

= 2000 / 1290

= 1.550 g/ml

The density of the drone is similar to density of carbon composite hence the drone of made of carbon composite

The bakers fits 26 rolls on to a pan that measures 1 5/8ft2. How many square feet does the baker use for each roll
mihalych1998 [28]

Answer: 1/16 ft²

Step-by-step explanation:

The baker put 26 rolls into a pan that has an area of 1⁵/₈ ft².

Each roll is therefore taking up a space of:

= Area/ Number of rolls

Convert the fraction to an improper fraction:

1 ⁵/₈ = 13/8

= 13/8 ÷ 26

= 13/8 * 1/26

= 13/208

= 1/16 ft²

A compound experiment consists of tossing a coin, drawing a letter at random from the alphabet, and then tossing two coins. What
Artemon [7]
We should each take these probabilities first individually.
Probability of tails in a coin toss = 1/2
Probability of <span>drawing letter T from the alphabet = 1/26
Probability of 2 tails in 2 coin toss = 1/4
Sample space = {HH, TT, HT, TH}

Add these together since these events happen after another = 1/2 + 1/26 / + 1/4 = 41/52

The final probability is 41/52</span>
