Sara’s mother is now four times as old as Sara. In five years, she will be three times as old as Sara. What are their ages now?
Answer:
Sara's mother age : 40 years
Sara's age : 10 years
Step-by-step explanation:
Let Sara's mother age be x
and Sara age be y
Given , Sara's mother is now four time as old as Sara
• x = 4y ...1
also, in five years , she will be three times as old as Sara
In five years , Sara's mother age :- ( x + 5 )
Sara age :- ( y + 5 )
according to the question,
x + 5 = 3 ( y + 5 )
x + 5 = 3y + 15
x - 3y = 10 ... 2
putting value of x from 1 into 2
4y - 3y = 10
y = 10
putting y value in 1
x = 4y = 4 ( 10 ) = 40
So, Sara's mother age is 40years
and Sara's age is 10years .
can you find x and y

find the exponential growth formula
Using an exponential equation, it is found that the estimate for the park's elephant population for the year 2020 is of 12967.
An increasing exponential equation is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem:
In 2010, there were 8350 elephants, hence [tex]A(0) = 8350[/tex].Growth rate of 4.5%, hence [tex]r = 0.045[/tex]Then:
[tex]A(t) = 8350(1 + 0.045)^t[/tex]
[tex]A(t) = 8350(1.045)^t[/tex]
2020 is 10 years after 2010, hence, we have to find A(10).
[tex]A(10) = 8350(1.045)^{10} = 12967[/tex]
The estimate for the park's elephant population for the year 2020 is of 12967.

Step-by-step explanation:
In which quadrant(s) do the graphs of y=x^2 and y=3x+10 intersect?
Answer:
Quadrants I and II
Step-by-step explanation:
y = x²
y = 3x + 10
x² = 3x + 10 Substitute x² for y
x² - 3x - 10 = 0 set the equation = 0
(x - 5) (x + 2) Factoring
x - 5 = 0 ; x + 2 = 0
x = 5 or x = -2
Now solving the y
y = x² or y = x²
y = (5)² or y = (-2)²
y = 25 or y = 4
The points of interception is points (5, 25) or (-2, 4)
(5, 25) in Quadrant I ; (-2, 4) in Quadrant II

Kilogramo= $20.50
100 Kilogramos= $2050.00
20.50×100=2050.00
1) Todo número entero multiplicado por un múltiplo de 10 hereda los ceros de aquel múltiplo.
2) Si el número es decimal, entonces la coma es desplazada una cantidad de posiciones a la derecha equivalente a esos ceros heredados.
3) 100 kilogramos de frijol cuestan $ 2050.
1) Los casos a realizar sin necesidad de calculadora están correctamente desarrollados, puesto que observan la regla mnemotécnica de que todo número entero multiplicado por un múltiplo de 10 hereda los ceros de aquel múltiplo.
2) De manera semejante a 1), los casos a realizar sin necesidad de calculadora están correctamente desarrollados. Si el número es decimal, entonces la coma es desplazada una cantidad de posiciones a la derecha equivalente a esos ceros heredados.
3) La cantidad total ([tex]C[/tex]), en pesos, por 100 kilogramos de frijol es igual al precio unitario ([tex]c[/tex]), en pesos por kilogramo, por la masa comprada ([tex]m[/tex]), en kilogramos, es decir:

2. Given h(x) = x2 +11 and g(x) = √ x-2 evaluate : (g∘ h) (0)
Step-by-step explanation:
I understand from the corrupted typing of the problem text that we have 2 functions :
h(x) = x² + 11
g(x) = sqrt(x - 2)
we are looking for (g○h)(0).
first of all, (g○h)(0) is the same as g(h(0)).
don't get in panic because of this one iteration sign.
it just means we are running the second function first, and use that result as argument for the first function. that's all.
so,
h(0) = 0² + 11 = 11
11 is now the argument for g(x).
g(11) = sqrt(11 - 2) = sqrt(9) = 3
(g○h)(0) = 3

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x-15)^{\circ}∠A=(7x−15)
∘
and m\angle B=(2x-3)^{\circ}∠B=(2x−3)
∘
, then find the measure of \angle A∠A.
Answer:
m ∠ A = 139° ; m ∠ B = 41°
Step-by-step explanation:
Supplementary angles sum = 180°
m ∠A + m ∠ B = 180°
(7x - 15) + (2x - 3) = 180°
9x - 18 = 180°
9x = 180 + 18
9x = 198°
x = 22
m ∠A = 7x - 15 = (7·22) - 15 = 154 - 15 = 139°
m ∠ B = 2x - 3 = (2·22) - 3 = 44 - 3 = 41°
Check: m ∠ A + m ∠ B = 180°
139° + 41° = 180
