Help w Geometry !!!!
Answer:
[tex]x=21[/tex]
Step-by-step explanation:
Hi there!
We're given that angle POR measures 90 degrees. Ray OQ bisects it, meaning it splits it into two equal angles.
90 ÷ 2 = 45.
This means that each of those individual angles are 45 degrees. This means:
[tex]2x+3=45[/tex]
Solve:
[tex]2x=42\\x=21[/tex]
Therefore, x=21.
I hope this helps!

The correct answer is : -0.7
A correlation coefficient is a statistical indicator of how well changes in one variable's value predict changes in another. There is a common tendency to assume that a change in one variable must be the result of a change in the other when the fluctuation of one variable predicts a similar fluctuation in another variable with high accuracy.
Correlation does not necessarily indicate cause, though. For instance, there might be an unidentified factor that has a similar impact on both variables. When it comes to consumer data patterns, being able to distinguish between correlation and causation can be useful and provide insightful information. In the context of marketing, the beer and diapers example is frequently used to illustrate this.
The correlation coefficient is close to: -0.7 (negative because there is an inverse relationship)
Based on this information, we can conclude that Amélie's cake sales are affected by the daily temperature.
Therefore, the final answer is : -0.7.

A recipe for lemonade calls for 14 lemons for every 2 cups of sugar. If you have 84 lemons to use for making lemonade, how many cups of sugar will you need?
Answer: about 15 because 14x7=78 and 2 cups for every 14 so 7x2 is 14 and there is 6 remaining so 15 is about right
thank biggie not me
12 cups of sugar needed.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
for 14 lemons= 2 cups of sugar need.
for 1 lemon= 2/14 cups of sugar need.
Now, for 84 lemons
=84*2/14
=6*2
=12 cups of sugar need.
Hence, 12 cups of sugar needed.

Answer:
x=50°
Step-by-step explanation:
x+3°+x+20°+x+7°=180°
or,3x+30°=180°
or,3x=150°
or,x=50°
Answer:
50
Step-by-step explanation:
→ First add all the angles together as angles on a straight line add to 180°
x + 3 + x + 20 + x + 7 = 180
→ Simplify
3x + 30 = 180
→ Minus 30 from both sides
3x = 150
→ Divide both sides by 3
x = 50

Alyssa bought 2 packs of football cards for $4.52 each, and a deck of Digimon Cards
for $11.47 with two $20 bills. Alyssa found $7.72 in her pocket. How much change
did Alyssa get?
Hello :D
2 x $4.52 = $9.04
$9.04 + $11.47 = $20.51
2 x $20 = $40.00
$40.00 - $20.51 = $19.49
With change:
$40.00 + $7.72 = $47.72
$47.72 - $20.51 = $27.21

If the geometric mean of a and 34 is 6 sqrt(17) find the value of a
Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements, [tex](n_1, n_2, ..., n_n)[/tex], is given by:
[tex]G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}[/tex]
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
Two elements(n = 2), a and 34.[tex]G = 6\sqrt{17}[/tex]Thus:
[tex]\sqrt{34a} = 6\sqrt{17}[/tex]
We find the square of each side, so:
[tex](\sqrt{34a})^2 = (6\sqrt{17})^2[/tex]
[tex]34a = 36\times17[/tex]
Simplifying both sides by 17:
[tex]2a = 36[/tex]
[tex]a = \frac{36}{2}[/tex]
[tex]a = 18[/tex]
The value of a is 18.

2. The area of Mr. Bodus rectangular farm is 5500 cm², its width is 11 m find the length of the farm
Answer:
5 m
Step-by-step explanation:
We convert m to cm by adding 2 zeroes. So 11m = 1100 cm
A = l*w
where l = length and w = width
so w = 11 m
we are looking for l (length)
so set up an equation,
5500 = 11 * l
and divide by 11 on both sides
5500 / 11 = l = 500 cm
Check: 11 * 500 = 5500
We can remove two zeroes to get the value in meters.
500 cm = 5 m
