Answer: 18
Step-by-step explanation: The ratio 3:9 is equivalent to 1:3. This means that whatever number on the left side of the ratio should be multiplied by 3 to get the one on the right. 6 x 3 = 18.
The value of the unknown number for the fraction is equal to 18.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio is 3:9 then the value of the unknown number will be calculated as,
The ratio 3:9 is equivalent to 1:3. This means that whatever number is on the left side of the ratio should be multiplied by 3 to get the one on the right.

solve for x? please help
Answer:
x = [tex]\sqrt{10}[/tex]
Step-by-step explanation:
The 2 right triangles and the outer right triangle are similar, then ratios of corresponding sides are equal, that is
[tex]\frac{x}{5}[/tex] = [tex]\frac{2}{x}[/tex] ( cross- multiply )
x² = 10 ( take the square root of both sides )
x = [tex]\sqrt{10}[/tex]
Answer:
√10
Step-by-step explanation:
taking the smallest triangle;
y as the hypotenuse, x as the adjacent side, 2 as the opposite side
then: y²=x²+2²
x²=y²-2²= y²-4
taking the other triangle;
z as the hypotenuse, x as the adjacent side, 5 as the opposite side
then: z²=x²+5²
x²=z²-5² = z²-25
take both equations,
x²= y²-4
x²= z²-25
y²-4= z²-25
y²= z²-25+4 = z²-21
taking the biggest triangle (whole triangle);
(5+2)= 7 as the hypotenuse, z as the adjacent side, y as the opposite side
then; 7²=z²+y²
z²+y²=7² =49
but y²= z²-21;
z²+y² =49
z²+ z²-21 =49
2z²-21=49
2z²=49+21= 70
z²= 70/2 = 35
take x²= z²-25
x²= 35-25 = 10
[tex]x = \sqrt{10} [/tex]

Chipotle Burritos are normal distributed with a mean length of 200mm and a standard deviation of 8mm. What is the probability that a burito picked at random is shorter than 190mm?
Answer: 0.1056
Step-by-step explanation:
Given: Chipotle Burritos are normal distributed with
Mean = 200 mm
Standard deviation = 8 mm
Let x be the length of a random burrito.
The probability that a burrito picked at random is shorter than 190mm will be :
[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]
Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

Of the seeds Quincey planted in his tomato garden, 75% grew into mature plants. If Quincey has 39 tomato plants in his garden, how many seeds did he plant?
PLEASE HELP WORTH 70 POINTS
Answer:
52 seeds.
Step-by-step explanation:
So, 3/4 of his plants have grown. SO, 3/4 = 39 plants, and if we divide by 3, we get 1/4 of the plants are 13 plants. SO, if we want to find 4/4, we can multiply 13*4=52 seeds.
Quincey planted 52 seeds in total.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
75% grew into mature plants.
If Quincey has 39 tomato plants in his garden.
let x number of seed he planted.
So, 75% of x= 39
75x/100= 39
75x = 3900
x = 52
Hence, He planted 52 seeds.
