in order for them to be triangle lengths the two shorter size added together have to be greater than the longest side and in each answer choice if you add the two shorter sides none of them are greater than the longer side if that makes sense
Answer: what you need to find is the one where the two lowest numbers add up to be bigger than the biggest number. For example, if it was 3,7,5 then those could be right because 5+3=8 and 8 is bigger than 7. It is supposed to be that any two added is bigger than the third, but it's mist important that the smaller numbers equal more than the third

This year Goran watched movies. He thought that of them were very good. Of the movies he watched, what percentage did he rate as very good?
Answer: 80%
Step-by-step explanation:
Goran watched 55 movies. Out of those movies, he thought 44 were very good.
The question needs to know what percentage this 44 very good movies comprised of the total number of movies.
= Number of very good movies / Total movies * 100%
= 44 / 55 * 100%
= 0.8 * 100%
= 80%

A bag contains 9 red tiles, 10 blue files, and 6 green tiles. A tile is randomly drawn from the bag. Which statement is true?
A. The probability of drawing a red tile is 36% and the probability of NOT drawing a red tile is 64%.
B.
The probability of drawing a blue tile is 30% and the probability of NOT drawing a blue tile is 70%.
C. The probability of drawing a green tile is 25% and the probability of NOT drawing a green tile is 75%.
D. The probability of drawing a red tile is greater than the probability of NOT drawing a green tile. David hiked 24 miles in Ahon-
Answer: A. The probability of drawing a red tile is 36% and the probability of NOT drawing a red tile is 64%
Step-by-step explanation:
Number of red tiles = 9
Number of blue files = 10
Number of green tiles = 6
Total number of tiles = 9 + 10 + 6 = 25
Probability of drawing red tile = 9/25 = 0.36 = 36%
Probability of drawing blue tile= 10/25 = 0.40 = 40%
Probability of drawing green tile = 6/25 = 0.24 = 24%
Based on the explanation above, the correct answe is option A "The probability of drawing a red tile is 36% and the probability of NOT drawing a red tile is 64%".

SOMEONE HELP ME PLEASE I NEED IT, it needs to be in radical form
Step-by-step explanation:
step 1. let's call the line in the middle y.
step 2. y = sqrt(5^2 + 7^2) = sqrt(74). pythagorean theorem.
step 3. x^2 + y^2 =100 (pythagorean theorem))
step 4. x^2 + (sqrt(74))^2 = 100.
step 5. x^2 = 100 - 74
step 6. x^2 = 26
step 7. x = sqrt(26). note: sqrt is the square root.
The value of the x is [tex]\sqrt{26}[/tex].

Sec^2x+4secx=-4
Answer:
x = 120°
Step-by-step explanation:
We are given;
sec²x + 4secx = -4
Rearranging gives;
sec²x + 4secx + 4 = 0
Factorizing the left hand side gives;
(sec x + 2)(sec x + 2) = 0
This means that;
(sec x + 2) = 0
From trigonometry, we know that sec x = 1/cos x
Thus;
(1/cos x) + 2 = 0
1/cos x = -2
cos x = -1/2
cos x = -0.5
x = cos^(-1) -0.5
x = 120°

Here is 16 divided by 1/4 displayed mathematically in colors:
16
÷
1
4
The numbers in 16 divided by 1/4 are labeled below:
16 = whole number
1 = numerator
4 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
16 x 4
1
=
64
1
Thus, the answer to 16 divided by 1/4 in fraction form is:
64
1
To make the answer to 16 divided by 1/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
64 / 1 = 64
The answer is rounded to the nearest two decimal points if necessary.
64/1 is an improper fraction and should be written as 64.

Determine the area of the triangle when tana=1 the image is in the picture above
Answer:
The area will be:
[tex]A=18(1+\sqrt{3}) \: u^{2}[/tex] or [tex]A=49.18 \: u^{2}[/tex].
Step-by-step explanation:
Using the definition of tangent, we have:
[tex]tan(\alpha)=\frac{6}{\vec{AB}}[/tex]
We know that tan(α) = 1, then we can find AB
[tex]1=\frac{6}{\vec{AB}}[/tex]
[tex]\bar{AB}=6\: u[/tex]
u means any unit.
Now, we need to find the distance BC. If the angle ∠D is 60°, then ∠C must be 30°. Using the tangent definition in the triangle BCD we have:
[tex]tan(30)=\frac{6}{\bar{BC}}[/tex]
[tex]\bar{BC}=\frac{6}{tan(30)}[/tex]
[tex]\bar{BC}=\frac{6}{1/\sqrt{3}}[/tex]
[tex]\bar{BC}=6\sqrt{3} \: u[/tex]
So, the base of the triangle will be:
[tex]b=\bar{AB}+\bar{BC}=6+6\sqrt{3}=6(1+\sqrt{3}) \: u[/tex]
The area of a triangle is given by the following equation:
[tex]A=\frac{b*h}{2}[/tex]
b is the base ([tex]b=6(1+\sqrt{3})\: u[/tex])h is the height (h=6 u)[tex]A=\frac{6(1+\sqrt{3})*6}{2}[/tex]
[tex]A=18(1+\sqrt{3})[/tex]
Therefore, the area will be [tex]A=49.18 \: u^{2}[/tex].

2. Determine the value of each variable for parallelogram INDY has diagonals that intersec at P.1P=3x DP = 6x - 2 NP = 3y and YP=7x-2,
Answer:
x = 2/3 and y = 8/9
Step-by-step explanation:
If a parallelogram INDY has diagonals that intersects at P, then O bisects ID and YN
Hence IP = PD and NP = YP
Given
IP=3x
DP = 6x - 2
NP = 3y and
YP=7x-2,
Substitute
3x = 6x-2
3x-6x = -2
-3x = -2
x = 2/3
x = 0.67
Also NP = YP
3y = 7x-2
3y = 7(2/3) - 2
3y = 14/3 - 2
3y = 14-6/3
3y = 8/3
9y = 8
y = 8/9
Hence x = 2/3 and y = 8/9

a. If I doubled the money in my savings account, I would have $150.62.
b. three times the hourly wage plus $7.65 in tips equals $27.90
Answer: See explanation
Step-by-step explanation:
a. Let the money in m savings account be represented by x.
If I doubled the money in my savings account, I would have $150.62. This means that:
(2 × x) = $150.62
2x = $150.62
Divide both side by x
2x/2 = $150.62/2
x = $75.31
The amount in the savings account is $75.31
b. Let the hourly wage be represented by x.
Three times the hourly wage plus $7.65 in tips equals $27.90. This will be:
(3 × x) + 7.65 = 27.90
3x + 7.65 = 27.90
3x = 27.90 - 7.65
3x = 20.25
x = 20.25/3
x = 6.75
The hourly wage is $6.75

The circumference when the area of a circle is 16π ft² is 8π feet.
How to calculate the area?The area of a shape simply means the total space that is taken by the shape. It simply expresses the extent of the region on a particular plane as well as a curved surface.
From the information given the area of a circle is 16π ft² be we want to calculate the circumference, in feet. This will be Illustrated this:
Circumference of a circle = 2πr
Area of a circle = πr²
r = radius.
Therefore, based on the information regarding the area given, the radius will have to be calculated first.
Area = 16π
πr² = 16π
r² = 16π / π
r² = 16
r =✓16
r = 4
Radius = 4ft.
Therefore, the circumference will be:
= 2πr
= 2 × π × 4
= 8π
Circumference is 8π feet.

3. What is the greatest common factor of 6 and 16? *
Answer:
2
Step-by-step explanation:
2 is the only factor that goes into 6 and 16. (6th's Factors) 1, 2, 3 and 6
(16th Factors) 1, 2, 4, 8 and 16.
The greatest common factor of 6 and 16 is 2.
To find the greatest common factor (GCF) of 6 and 16, we need to determine the largest number that can divide both 6 and 16 without leaving a remainder.
First, we find the factors of each number:
Factors of 6: 1, 2, 3, 6
Factors of 16: 1, 2, 4, 8, 16
By comparing the factors, we can identify that both 6 and 16 have a common factor of 2. However, 6 also has a factor of 3, which is not a factor of 16.
To determine the GCF, we select the highest common factor, which is 2.
Therefore, the greatest common factor of 6 and 16 is 2.
The GCF is an essential concept in mathematics as it helps simplify fractions, factorize expressions, and solve various mathematical problems. It allows us to identify the largest number that can evenly divide two or more given numbers.
