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

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.

Find f(2) if f(x)=5x⁵-3x⁴- 17x³-4x²+10x+21 F(2)=
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
f(2)=160-48-136-16+20+21
f(2)=1

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

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.

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:
