Given 10 is a leg of a right triangle and 11 is the hypotenuse, what is the length of the other leg of the right triangle? Round
Vou answer to the nearest hundredi derinals
Answer:
The length of other leg is 4.58
Step-by-step explanation:
It is given that:
One leg of triangle = 10
Hypotenuse = 11
Using Pythagorean theorem,
[tex]a^2+b^2=c^2\\(10)^2 + b^2 = (11)^2\\100+b^2 = 121 \\b^2 = 121-100 \\b^2 = 21[/tex]
Taking square root on both sides
[tex]\sqrt{b^2}=\sqrt{21}\\b=4.58[/tex]
Therefore,
The length of other leg is 4.58

Mr. Smith has 7 1/5 pounds of clay and wants to give 3/5 of a pound to each of her
students. How many students does Ms. Smith have enough clay for?
A.9. B.12
C.15 D.18
Answer:
B. 12
Step-by-step explanation:
you convert 7 1/5 into an improper fraction which gives you 35/5
then you add the 1/5 giving you 36/5.
you divide 36/5 ÷ 3/5 and that gives you 12.
What is the diameter of the inscribe circle of the triangle?
============================================
Work Shown:
The two angle bisectors intersect to form the incenter. The incenter is the center of the inscribed circle (aka "incircle"). This circle is the largest possible, but is completely inside the triangle. No portions of the circle spill outside the triangle.
The two segments marked with lengths x+8 and 2x-5 are two radii of the incircle. This is because the sides of the triangle are tangent to the incircle.
Since all radii are the same length, we can set those expressions equal to one another and solve for x
x+8 = 2x-5
x-2x = -5-8
-x = -13
x = 13
This x value then leads to
x+8 = 13+8 = 212x-5 = 2*13-5 = 26-5 = 21Both radii are 21 units long, which helps confirm we have the proper x value. We double the length of the radius ot get the diameter.
So the diameter of the incircle is 2*21 = 42 units long.

Use the Factor Theorem to show that (x - 3) is a factor of the polynomial
P(x) = x^5-3x^4+5x^3-15x^2-6x+18
Answer:
P(3) = 0
Step-by-step explanation:
Factor Theorem is a consequence of Remainder Theorem.
Remainder Theorem states that if polynomial f(x) is divided by a binomial (x - a) then the remainder is f(a).
Factor Theorem states that if f(a) = 0, then the binomial (x - a) is a factor of f(x).
We have the polynomial
[tex]P(x) = x^5-3x^4+5x^3-15x^2-6x+18[/tex]
To prove that x-3 is a factor of P, we calculate P(3):
[tex]P(3) = 3^5-3*3^4+5*3^3-15*3^2-6*3+18[/tex]
[tex]P(3) = 243-243+135-135-18+18[/tex]
[tex]P(3) = 0[/tex]
Thus, x-3 is a factor of P(x)
20+20=40 because if u add ten again then it would be 10+10 and that. Would be 20 then 20+10 is 30 then 30+10 then that would be 40 so then 20+20= cause 2+2=4 then add the zero to get 40

the angle of a triangle are in ration 1:3:5 then what is the sum of all find the messure of each angle
Answer:
1 : 3 : 5 = 20° : 60° : 100°
Step-by-step explanation:
Let the angle of the triangle be x
Given the following data;
1 : 3 : 5 = x : 3x : 5x
We know that the sum of the sides of a triangle is equal to 180 degrees.
x + 3x + 5x = 180
9x = 180
x = 180/9
x = 20°
Now, to find the measure of each angle.
For the first side;
x = 20°
For the second side;
3x = 3*20 = 60°
For the third side;
5x = 5*20 = 100°

Jordan has a $150,000 home financed with a 30-year loan at 5%. If she
wished to pay one extra monthly payment each year, how many months will it
take her to pay off her mortgage?
A. 187 months
B. 230 months
C. 200 months
D. 304 months
Answer:
304 mo
Step-by-step explanation:
It would take her 304 months to pay off her mortgage, option D is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To calculate the number of months it will take to pay off the mortgage with one extra monthly payment per year, we can use the formula for the loan payoff period:
N = -log(1-(r/12)P)/log(1+r/12)
where N is the number of months, r is the monthly interest rate, and P is the monthly payment.
r = 0.05/12 = 0.004167
P = r(1+r¹²³⁰/(1+r)¹²³⁰-1) × 150,000
= $805.23
Now, we can calculate the number of months it will take to pay off the mortgage with one extra monthly payment per year:
N = -log(1-(r/12)P)/log(1+r/12)
N = -log(1-(0.004167/12)×805.23)/log(1+0.004167/12)
N = 303.85
Hence, it would take her 304 months to pay off her mortgage, option D is correct.

Answer:
The answer is [tex]120a\sqrt{7a}[/tex]
Step-by-step explanation:
This question can be solved simplifying the square roots, and then multiplying what is inside and what is outside the roots. So
[tex]3\sqrt{5a}*8\sqrt{35a^2}[/tex]
Square root of [tex]a^2[/tex] is a. So
[tex]3\sqrt{5a}*8\sqrt{35a^2} = 3\sqrt{5a}*8a\sqrt{35} = 24a\sqrt{5a}\sqrt{35}[/tex]
Now we simplify the square roots. 35 = 5*7. So
[tex]24a\sqrt{5a}\sqrt{35} = 24a\sqrt{5a}\sqrt{5*7} = 24a\sqrt{a*5^2*7} = 24a*5\sqrt{7a} = 120a\sqrt{7a}[/tex]
The answer is [tex]120a\sqrt{7a}[/tex]
