Answer:
fourth and fifth
Step-by-step explanation:
If George gets a 20% raise, that means he will now earn
$445 + $445*20% = $445 + $445*0.2 = $445*1 + $445*0.2 = $445*(1 + 0.2) = $445 * 1.2
So we know the fourth is correct.
We also know that current pay is 100% of current pay and the new pay will be 120% of current pay, so x/455 must be equal to 120% / 100% which is equal to 120/100, so fifth is correct too.

If ab = 9 and a² + b² = 81, then (a+b)² = ?
Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that
[tex](a+b)^2=a^2+2ab+b^2[/tex]
We have the a² and the b² in the equation [tex]a^2+b^2=81[/tex], and we almost have a 2ab in the equation [tex]ab=9[/tex]. To get that 2ab, we can simply double both sides of the first equation to get [tex]2ab=18[/tex]. From there, we'll add the first two equations together, giving us the summed equation
[tex]a^2+b^2+2ab=81+18\\a^2+2ab+b^2=99[/tex]
And since [tex](a+b)^2=a^2+2ab+b^2[/tex], we can equivalently say that
[tex](a+b)^2=99[/tex]

An isosceles triangle is one with two equal-length sides. The value of x is 58°.
What is an isosceles triangle?An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.
Since the given triangle is an isosceles triangle, therefore, the angle opposite to side 6.25 units will be equal, therefore, the sum of all the angles of the triangle will be,
61° + 61° + x = 180°
x = 58°
Hence, the value of x is 58°.

What is an arc?An arc is a part of a curve that is a continuous portion of the circumference of a circle or an ellipse. It is defined by two endpoints and the arc itself, which is the curved section between the endpoints.
Given:
arc QU = 88 and <QUA = 111
So, QDA = 2 <QUA
= 2 X 111
= 222
Now, QUA = 360- 222 = 138
and, arc AU = QUA - arc QU
= 138- 58
= 50
Hence, the measure of AU is 50.

What is the answer to (2³)³? Explain or show your work.
Answer:
(2³)³=512
because, 2³=8 & 8³=512
Answer:
512
Step-by-step explanation:
Ok, let's start by deciphering how powering works:
[tex]a^3 = a \cdot a \cdot a\\a^b * a^c = a^{b+c}\textrm{; because it's "multiply a b times" multiplied by "multiply a c times"}\\(a^b)^c = a^{b\cdot c}\textrm{; because of the above}\\[/tex]
[tex](2^3)^3 = 2^{3\cdot3} = 2^9\\[/tex]
and because of KibiBytes existing, we know that 2^10 = 1024, so 2^9 will be equal to 1024/2=512

Maria is shopping for party supplies. She finds that paper plates come in packages of eight, napkins come in packages of 10, and paper cups come in packages of 12, what is the least number of packages of plates napkins and cups she has to buy so that she has the same number of each Item for her birthday party.
Answer
15 plates, 12 napkins and 10 cups
Step-by-step explanation:
To find the least amount, you have to find the lcm of all three numbers. In this case the lcm of 8,10, and 12 is 120. Afterwards you need to divied 120 by all numbers. So 120 divided by 8 is 15, so 15 plates. 120 divided by 10 is 12, so 12 napkins and finally 120 divided by 12 is 10, so 10 cups
The least number of packages of plates, napkins, and cups Maia has to buy so that she has the same number of each Item for her birthday party is 15, 12, and 10, respectively.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given that paper plates come in packages of eight, napkins come in packages of 10, and paper cups come in packages of 12. Therefore, to find the least number of packages of plates napkins and cups Maria has to buy so that she has the same number of each Item for her birthday party, we need to take the LCM of the following.
LCM of 8, 10, and 12 = 120
Now, the number of packages,
[tex]\text{Number of paper plate packs} = \dfrac{120}{8}=15[/tex]
[tex]\text{Number of napkins pack} = \dfrac{120}{10}=12[/tex]
[tex]\text{Number of paper cups pack} = \dfrac{120}{12}=10[/tex]
Hence, the least number of packages of plates, napkins, and cups Maia has to buy so that she has the same number of each Item for her birthday party is 15, 12, and 10, respectively.

Find the value of x. Round your answer to the nearest tenth.
That's a question about the Pythagorean Theorem.
We use the Pythagorean Theorem to find the value of one side in a right triangle.
This theorem says that:
[tex]\boxed{a^2 = b^2 + c^2}[/tex]
a is the hypotenuse (It's the opposite side the right angle).b and c are cathetus (They're the adjacent sides the right angle).Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of x (the hypotenuse). Let's change this information in that formula.
[tex]a^2 = b^2 + c^2\\x^2 = 10^2 + 7^2\\x^2 = 100 + 49\\x^2 = 149\\x = \sqrt{149}[/tex]
Therefore, the value of x is [tex]\sqrt{149}[/tex].

[tex]\Huge\boxed{76}[/tex]
Step-by-step explanation:
Hello There!
The first thing we want to do is find the proportional relationship between to two triangles
The smaller triangles longest side is 18
Given the longest side of the similar triangle we can divide the longest side of the preimage by the longest side of the similar triangle
So the proportional relationship would be
36/18 or 2
Our next step is to find the the sides of the similar triangle
To do so we multiply the sides of the preimage by 2 (because 2 is the proportional relationship between the two triangles)
12x2=24
8x2=16
and we already know that the longest side measures 36
Now we can find the perimeter by adding all of the side lengths
36+24+16 = 76
So we can conclude that the perimeter of the dilated image is 76
The perimeter of the dilated triangle is 81.
