Find m < b
Picture Included
Answer:
<b= 48 degree
Step-by-step explanation:
<A + <B + <C = 180 degree (Sum of angles in a triangle)
<A = 90 degree
<B = 2x + 14 degree
<C = 4x - 26 degree
[tex]90+2x+14+4x-26=180 degree\\2x+4x=180+26-90-14\\6x=102\\x=\frac{102}{6} \\x=17 degree\\[/tex]
Therefore, <B = 2x + 14 = 2(17) + 14 = 34 + 14 = 48
<b = 48 degree
Please help!!! I’ll mark brainliest!!!!!!! Please explain!
Answer:
[tex]y = 2x + 12[/tex]
By the fiftieth year, there will be 112 wolves ([tex]y = 2[/tex] × [tex]50 + 12[/tex])
Step-by-step explanation:
You start with 12 wolves in the population.
Each year, the wolf population will increase by 2 years.
Let x represent the number of years.
Let P represent the total population.
Considering all this, P = 2x + 12.
In this case, we want to find how many wolves will be in the population in 50 years. Therefore, we will need to plug 50 into the equation in place of x.
P = 2(50) + 12

Вася вырезал из картона треугольник и пронумеровал его вершины цифрами 1, 2, 3. Оказалось, что если Васин треугольник повернуть 18 раз по часовой стрелке вокруг его вершины под номером 1 на угол, равный углу при этой вершине, то он вернется в исходное положение. Если Васин треугольник повернуть 3 раза по часовой стрелке вокруг его вершины под номером 2 на угол, равный углу при этой вершине, то он вернется в исходное положение. Вася утверждает, что если повернуть его треугольник n раз вокруг вершины под номером 3 на угол, равный углу при этой вершине, то он вернется в исходное положение. Какое минимальное n мог назвать Вася так, чтобы его утверждение было правдивым хотя бы для какого‑то картонного треугольника?

(ar^b)³ = 125r²⁴
where a and b are positive integers
work out a and b
I dont really care about the answer I just want the working out and the reason why
Answer:
a=5 b=8
Step-by-step explanation:
[tex] {(a {r}^{b} )}^{3} = 125 {r}^{24} [/tex]
[tex] {(a {r}^{b} )}^{3} = {5}^{3} {r}^{24} [/tex]
{125 = 5×5×5 = 5³}
[tex]{(a {r}^{b} )}^{3} = {(5 {r}^{8}) }^{3} [/tex]
{Taking 3 power outside to get 5r⁸}
{Then match the positive integer with a and b}
Therefore,
a= 5
b= 8

You have a pile of 45,000 candies. You are going to give away 18% every day. USING THE EXPLICIT EQUATION how many candies will you have left after 5 days. Round you answer to the nearest whole candy
Answer:
16683 candiesStep-by-step explanation:
Given:
Initial value is 45000.Reduction per day is 18%.The equation would be:
[tex]C(t) = 45000*(1 - 0.18)^t=45000*0.82^t[/tex], where C(t) is the number of candies left after t daysFind the value of C(5):
C(5) = 45000*0.82⁵ ≈ 16683 rounded[tex]\\ \sf\longmapsto C(t)=P\left(1-\dfrac{R}{100}\right)^t[/tex]
[tex]\\ \sf\longmapsto C(t)=45000\left(1-\dfrac{18}{100}\right)^t[/tex]
[tex]\\ \sf\longmapsto C(t)=45000(1-0.18)^t[/tex]
[tex]\\ \sf\longmapsto C(t)=45000(0.82)^t[/tex]
Now
[tex]\\ \sf\longmapsto C(5)=45000(0.82)^5[/tex]
[tex]\\ \sf\longmapsto C(5)=45000(0.37)[/tex]
[tex]\\ \sf\longmapsto C(5)\approx16650[/tex]
I have one more to goooo
Answer:
Your answer should be B) a =2 I hope this helps you! Goodluck! :D
a - 17 = -15
Add 17 to both sides
a - 17 + 17 = -15 + 17
(-15 + 17 is the same as 17 - 15)
a = 2
Hope this helps!! :)

A small school has 78 students. If 24 students are boys what is the ratio of girls to boys
Answer:
54 : 24
Step-by-step explanation:
Total: 78 students
Part (boys): 24 students
We can find the number of girls in the school by subtracting the number of boys from the total number of students.
Part (girls): Total - Part (boys) = 78 - 24 = 54
We now have the amount of girls and boys, so we can rewrite as a ratio of girls to boys.
Girls: 54
Boys: 24
Girls : Boys = 54 : 24
