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?
Answers
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 .

A stuntman falls from the top of a building 26 ft above the ground. The function h (t) -16t^2+26
gives the height of the man in feet after t seconds.
Answers
Answer:
let h(t)= 0 (because when it reaches the ground h=0)
0=-16t^2+116
16t^2=116
divide both sides by 16
t^2= 7.25
square root both sides to find t

∠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.
Answers
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

Answers
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:

In which quadrant(s) do the graphs of y=x^2 and y=3x+10 intersect?
Answers
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
