Answer:
39
Step-by-step explanation:
To solve this problem we can use a proportion:
150 : 100 = x : 26
x = (26*150)/100 = 39
Answer:
39
Step-by-step explanation:
150% of 26 is 39
on a calculator do 26 times 150% and it equally 39
another way to do it is do 26 divided by 2 which equals 13, then add 13 to 26 and you get 39

h(x) = x ^ 2 - 7x - 8 1) What are the zeros of the function? Write the smaller first, and the larger second smaller I largerx = 2 ) What is the vertex of the parabola ?
Answer:
The zeros are x = -1 and x = 8
The vertex is (3.5, -20.25)
Step-by-step explanation:
When we have a quadratic equation like:
y = a*x^2 + b*x + c
The zeros of the function are the values of x such that:
a*x^2 + b*x + c = 0
And the solutions are given by the Bhaskara's equation, which is:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
And the vertex is at:
x = -b/2a
The y-value at the vertex is the function evaluated in that point.
In this case, we have the equation:
h(x) = x^2 - 7*x - 8
Then:
a = 1
b = -7
c= -8
Replacing these in the Bhaskara's equation we get:
[tex]x = \frac{-(-7) \pm \sqrt{(-7)^2-4*1*(-8)} }{2*1} = \frac{7 \pm 9 }{2}[/tex]
Then the two solutions are:
x = (7 - 9)/2 = -2/2 = -1 (this is the smaller one)
and
x = (7 + 9)/2 = 16/2 = 8 (this is the larger one)
And we will have the vertex at:
x = -(-7)/2*1 = 7/2 = 3.5
Evaluating h(x) in 3.5 we get:
h(3.5) = (3.5)^2 - 7*(3.5) - 8 = -20.25
Then the vertex is the point:
(3.5, -20.25)

2. Currently, Yamir is twice as old as Pato. In three years, the sum of their ages will be 30. If Pato's current age
is represented by a, which of the following equations could be used to correctly solve for a?
(1) a + 2a + 3 = 30
.(2) a + 2a +6 = 30
(3) (a +3)+2(a +3) = 30
(4) a +2(a +6)= 30
Given:
Yamir is twice as old as Pato.
In three years, the sum of their ages will be 30.
Pato's current age is represented by [tex]a[/tex].
To find:
The equation that could be used to correctly solve for [tex]a[/tex].
Solution:
We know that, Pato's current age is represented by a, then
Yamir's age = [tex]2a[/tex]
After three years,
Pato's age = [tex]a+3[/tex]
Yamir's age = [tex]2a+3[/tex]
In three years, the sum of their ages will be 30.
[tex](a+3)+(2a+3)=30[/tex]
[tex](a+2a)+(3+3)=30[/tex]
[tex]a+2a+6=30[/tex]
Therefore, the correct option is 2.

the profit a company earns every month depends
Answer:
The profit that a company earns each month depend on the amount of product sold, p, for $855 each and the amount of money spent on rent, utilities, and other expenses, which always totals to $6,780. The CEO earns 15% of the profit.
ncome: p*855
Expenses: 6780
Profit = Income - expenses = 855p - 6780 = 855*250 - 6780 = 213750 - 6780 = 206970
CEO's earn = 15% * 206970 = 0.15*206970 = 31,045.5

That's the circumference. Now you want to take pi/6 part of the circumference.
pi / 6 part of the circumference / 2pi is what you are looking for.
(pi / 6 // 2 pi) * 18 pi = 1/12 * 18 pi = 3/2 pi

need help with working perimeter and area please
Answer:
Area = 228 m²
Perimeter = 60 m
Step-by-step explanation:
The figure given shows a rectangle that has a cut triangular portion.
✔️Area of the figure = area of rectangle - area of the triangular cut portion
= L*W + ½*bh
Where,
L = 20 m
W = 12 m
b = 20 - (8 + 8) = 4 m
h = 6 m
Plug in the values
Area = 20*12 - ½*4*6
Area = 240 - 12
Area = 228 m²
✔️Perimeter = perimeter of rectangle - base of the triangular cut portion
= 2(L + W) - b
L = 20 m
W = 12 m
b = b = 20 - (8 + 8) = 4 m
Plug in the values
Perimeter = 2(20 + 12) - 4
= 2(32) - 4
= 64 - 4
Perimeter = 60 m

Two of the angles in a triangle measure 81° and 86°. What is the measure of the third angle?
Answer:
13°
Step-by-step explanation:
The reason is because the sum of all the angles in a triangle add up to 180°, so to find the last angle you add 81°+86°=167°
Subtract: 180°-167°=13°

HELP ASAPPPPPP( i need it before 5:30)
Answer: I would say that x = 10 degrees
Step-by-step explanation:
The angle has a square, meaning it is a right angle. Right angles are 90 degrees, and you're given 80 degrees + x.
90 - 80 = 10
Hope this helps!
Answer:
10 degrees
Step-by-step explanation:
First off complementary angles require the sum of both adjacent angles to equal 90 degrees. You are already given the degrees of one of the adjacent angles so all you need to do is a geometric proof. 90 = 80 + x and subtract 80 from each side to get 10 = x.

Hasina and her sister Jaqa ride their bikes to school.
Hasina starts first. The equations show the distance
each girl is from home m minutes after Jada starts.
What is the solution of the system of equations? What
does this mean in this situation?
Hasina: d = 300m + 1,500
Jada: d= 300m
The solution to the system of equations is d = 300m, which means that after Jada starts, both Hasina and Jada will be 300m away from home.
The solution to the system of equations is d = 300m. This means that after Jada starts, both Hasina and Jada will be 300m away from home. This is because the equation for Hasina states that she is 300m + 1500m away from home. Since Jada is starting second, she will only be traveling 300m from home. Therefore, the solution of the system of equations is d = 300m.
To solve the system of equations, we can use substitution. First, we can substitute 300m for d in Jada's equation. This gives us 300m = 300m, which is a true statement. We can then substitute this value for d in Hasina's equation, which gives us 300m + 1500m = 300m. To solve for m, we can subtract 1500m from both sides, giving us 0 = -1500m. To isolate m on one side, we can divide both sides by -1500, giving us -1 = m. This means that after Jada starts, both Hasina and Jada are 300m away from home.
