Answer:

No matter what scale factor is dilated, the angles will not change.

My explanation:

A 30-60-90 right triangle (literally pronounced "thirty sixty ninety") is a special type of right triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees. The triangle is significant because the sides exist in an easy-to-remember ratio: 1:√3:2.

That is to say, the hypotenuse is twice as long as the shorter leg, and the longer leg is the square root of 3 times the shorter leg. You might also remember it as "X, 2X, and X roots of 3", which is how I remember it, but then you have to remember that 2X is actually the longest side, not X roots of 3.

Which side is which? The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be √3

times as long, and the side opposite the 90 degree angle will be twice as long. The triangle below diagrams this relationship. Remember that the longest side will be opposite the largest angle, and the shortest opposite the smallest angle.

Hopefully this helped, if not HMU and I will try to get you a better answer! :)

You are buying packages of beads to make bracelets. Each package costs $3 plus 7% tax. You have a gift card for $15, and you pla
julia-pushkina [17]

Answer:

Step-by-step explanation:

The funtion is:

C(p)= 3(p)+1.07 (1)

where: 3 is the package cost, p is the number of packages and 1.07 is the taxes

the cost could be equal or less than the gift card value so:

CC \leq 15 (2)

Replace 2 en 1

15\leq 3(p) x 1.07

3(p)\leq \frac{15}{1.07}

3p [tex]\leq14.02\\\\p\leq \frac{14.02}{3} \\\\p\leq 4.67[/tex]

It´s important to aprox the quantity to the minimum value so I can buy 4 packages

The reasonable domain is for all R because any number is a possible value of the independent variable

You were testing orange juice recipes it’s recipe calls for orange juice concentrate and water mix one has 4 cups of concentrate
Sav [38]

Answer:

First mixed is the most orangey.

Step-by-step explanation:

First:

Orange\ juice\ concentrate=4\ cups\\\\Water=6\ cups\\\\Tota\ content=4+6=10\ cups\\\\Percentage\ of\ orange\ juice\ concentrate=\frac{Orange\ juice\ concentrate}{Total\ amount}\times 100\\\\Percentage\ of\ orange\ juice\ concentrate=\frac{4}{10}\times 100=40\%

Second:

Orange\ juice\ concentrate=1\ cups\\\\Water=3\ cups\\\\Tota\ content=1+3=4\ cups\\\\Percentage\ of\ orange\ juice\ concentrate=\frac{Orange\ juice\ concentrate}{Total\ amount}\times 100\\\\Percentage\ of\ orange\ juice\ concentrate=\frac{1}{4}\times 100=25\%

Third:

Orange\ juice\ concentrate=2\ cups\\\\Water=4\ cups\\\\Tota\ content=2+4=6\ cups\\\\Percentage\ of\ orange\ juice\ concentrate=\frac{Orange\ juice\ concentrate}{Total\ amount}\times 100\\\\Percentage\ of\ orange\ juice\ concentrate=\frac{2}{6}\times 100=33.33\%

First mixed has highest percentage of orange juice. Hence first mixed is the most orangey.
