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.

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.

Answer:
m∠M = 47°
m∠R = 124°
Step-by-step explanation:
HOME = TRAP
Judging buy the picture there is only one corner that sticks out compared to the rest of the angles. Meaning that A and M are the same because they are the only angles that are easily identical to each other. Then match the letters using this information
m∠A = m∠M
m∠R = m∠O
m∠T = m∠H
m∠P = m∠E
Now all you need to find is m∠R and m∠M
m∠A = m∠M means m∠M = 47° since m∠A is 47°
Same concept goes for m∠R = m∠O.

You can text 44 words in 1 minute. Write a proportion to help you find
how many words you can type in 4 minutes. Which choice sets up the
proportion correctly and has the correct solution?
Answer:
176 words
Step-by-step explanation:
1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:
44 words = x
1 minutes = 4 minutes
2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.
3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!
4) multiplying 44 by 4 would get us our answer which is 176

Answer: f(2)=1
Step-by-step explanation:
This is a function-related problem. In order to solve f(2), you need to substitute the value into the original function.
-----------------------------------------------------------------------------------------
f(x)=5x⁵-3x⁴- 17x³-4x²+10x+21
f(2)=5(2)⁵-3(2)⁴- 17(2)³-4(2)²+10(2)+21

Which box plot represents the dot plot data?
I have pictured the possible answers.
Answer:
The first box plot is correct
Step-by-step explanation:
Answer:
A. With numbers 18, 21, 22, 23 and 25Step-by-step explanation:
Lets analyze the dot plot and work out 5 numbers.
We see the minimum score is 18 and maximum score is 25, these are the two numbers.
The scores
18 , 19, 19, 19, 21, 21, 21, 21, 22, 22, 22, 22, 23, 23, 23, 24, 24, 25Median of the data:
(22 + 22)/2 = 22Lower half
18 , 19, 19, 19, 21, 21, 21, 21, 22Median of lower half = 21Upper half
22, 22, 22, 23, 23, 23, 24, 24, 25 Median of upper half = 23We now have 5 number summary:
18, 21, 22, 23 and 25Looking at the box plots, we see the first one is reflecting the numbers we got.
a line is reflected. which of these could be the result?
Answer:
A
Step-by-step explanation:
I chose C on A P E X but it said the answer was A
The line is reflected it could be a result of the line or the point is congruent to the preimage. Hence the option A is correct.
Waht is relfected line ?A reflected line is a figure such as an image that is reflected when the image is congruent to the preimage. It point in the figure to the image across the fixed line. This fixed line is caleld as line of reflectance. It can done by coordinating the using the planes.

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]
