Step 1: Identify
Leg a = 35
Leg b = 12
Hypotenuse c
Step 2: Solve for c
Substitute in variables [Pythagorean Theorem]: 35² + 12² = c²[Hypotenuse] Rewrite: c² = 12² + 35²[Hypotenuse] Evaluate exponents: c² = 144 + 1225[Hypotenuse] Add: c² = 1369[Hypotenuse] [Equality Property] Square root both sides: c = 37Plz help!!! I need the answer quickly

Simplify the rational Expression
Answer:
[tex]\frac{x^2+2x}{x-3}[/tex]
Step-by-step explanation:
We need to factor out numerator and denominator in order to simplify the rational expression by cancelling common factors.
Numerator : x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)
Denominator (factoring by grouping):
x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)
Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:
x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)

If 6x-4 is 11 less than 25,what is the value of 9x
Answer:
27
Step-by-step explanation:
If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:
6x-4=25-11, what is the value of 9x?
Let's solve for x first by using the given information: 6x-4=25-11
1. 6x-4=25-11
2. 6x-4=14
3. (isolate x by adding 4 on both sides) 6x=18
4. x=3
The question asks for the value of 9x. Since we know x=3...
9x=9 times 3=27
9x=27

Select all expressions that are equal to 64 3/2
Answer:
(c)512 because64 times 1.5 equal 512.
Step-by-step explanation:
(c) 512
(b) 8 to the third power
(E) √64 to the third power
all of these equal 512
The equivalent expression to [tex]64^{3/2[/tex] is 8³, 512 and √64³.
What is exponent and power?Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.
The number of times a number is multiplied by itself is defined by the exponent. A mathematical term called the power illustrates the repeated multiplication of the same integer or factor.
Given:
[tex]64^{3/2[/tex]
Now, we know that 64 is square of 8.
so, [tex]64^{3/2[/tex]= [tex](8^2)^{3/2[/tex]
= 8³
= 512
So, the equivalent expression to [tex]64^{3/2[/tex] is 8³, 512 and √64³

you can buy 5 cans of green beans at the Village Market for $2.30 or you can buy 10 of them of best food for $5.10 which place is the better buy
Answer:
village market
Step-by-step explanation:
5 times 2.30 =11.5
10 times 5.10 =51
11.5 times 2 =23
51 to 23
brainliest please thank you
Answer:
Answer vary:
The better buy is 5 cans of green beans at the Village Market.
Step-by-step explanation:
honestly in my opinion that‘s my answer.
if 10 cans cost $5.10 and 5 cans cost $2.30, think about if you add another $2.30 for another 5 cans the cost is $4.60 and you get 10 cans. and that’s obviously cheaper than the other buy.
10 cans = $5.10
5 cans = $2.30.
(the 5 can offer)
2.30+2.30= $4.60
Find the equation of the exponential function that passes through the points (- 1, 1/6) and (1, 2/3) and Use the form y = c * a ^ x and show how you find the values of and a. Show all work , not just the final equation.
Will give Brainliest to the right answer with steps
Answer:
y = 1/3*2^xStep-by-step explanation:
Given function
y = c*a^xThe points (-1, 1/6) and (1, 2/3) lie on the graph
Substitute the values of x and y to get the system of equations:
1/6 = c*a^(-1) ⇒ 1/6 = c/a ⇒ a = 6c2/3 = c*a^1 ⇒ 2/3 = acSubstitute a and solve for c:
2/3 = 6c*c1/9 = c²c = √1/9c = 1/3Find a:
a = 6c = 6*1/3 = 2The equation of the function:
y = 1/3*2^x5(6p-3)-2 = 2(15p - 11)+5 one solution, no solution, infinite solution

Whenever he visits Hillsdale, Jason has to drive 33 miles due north from
home. Whenever he visits Arcadia, he has to drive 44 miles due east
from home. How far apart are Hillsdale and Arcadia, measured in a
straight line?
Answer:
We'll use the Pythagorean Theorem.
1.)Substitute in values from the text
33^2+44^2= X^2
2.)Add like terms
1,089+1,936= X^2
3.)Now, we have 3,025=X^2

A farmer packs eggs into cartons of 12. The farmer has 109
eggs. She wants to keep 13 of those eggs for her family.
How many cartons will the farmer be able to sell?
Answer:
109 divided by 12 is about 9.3 carton thingys so she would most likley sell 8
so she can keep some
Step-by-step explanation:
The farmer sells 6 cartoons.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total Eggs= 109
A carton contain= 12 eggs
If the farmer takes away 13 eggs, the eggs left
= 109 - 13
= 96 eggs.
So, the number of cartoons will famer sell
= 96 / 12
= 6 cartoons.
Hence, the farmer sells 6 cartoons.

The admission fee at a park is $1.25 for children and $5.40 for adults. On a certain day, 319 people entered the park, and the admission fees collected totaled $1125. How many children and how many adults were admitted?
Answer:
So 900 children went that day and
225 adults went that day
Step-by-step explanation:
1125 divided by 1.25=900 children
so then if you want to find out adults then just subtract
1125-900=225 adults
