Step-by-step explanation:
Expresar lo siguiente como fracciones.
a) Los 4 meses del año
Hay 12 meses en un año. Entonces, la fracción de 4 meses de 12 meses en un año es:
= 4/12
= 1/3
b) Un día de la semana
Hay 7 días en una semana.
Así, la fracción de 1 día en una semana será:
= 1/7
c) Las tres provincias de la región Costa ecuatoriana
En la región de la Costa Ecuatoriana, hay cinco provincias presentes.

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal
costs $78.86 before the discount, and they leave a 20% tip. If the tip applies to the cost of
the meal before the discount, what is the total cost of the meal? Round your intermediate
calculations and answer to the nearest cent.
Answer: $80.44
Step-by-step explanation:
First of all, find 20% of 78.86, which is approximately 15.77.
Then, add it to the cost of the meal.
Finally, discount 15% of 94.63, which is approximately $14.19, and then subtract it from $94.63, and there's your answer.
A cylinder has a base radius of 10m a height of 18m. What is its volume in cubic
m, to the nearest tenths place?
Answer:
5656 m^3
Step-by-step explanation:
Volume of a cylinder can be calculated using below formula
V = πr²h
Where
h= height =18m
r= radius= radius = 10m
If we substitute the values we have
V = π × (10)²× 18
= 5655.6 m^3
= 5656 m^3
Answer: 5654.9

Answer:
A. f(x) = (x -3)² -1
B. vertex: (3, -1); axis of symmetry: x=3; x-intercepts: {2, 4}; y-intercept: 8
C. see attached for a graph
Step-by-step explanation:
A. Put the function in vertex form by completing the square. Start by putting parentheses around the terms containing x.
f(x) = (x² -6x) +8
Now, identify the coefficient of x (-6) and square half of that. (-6/2)² = 9. Add this value inside parentheses, and subtract this value outside parentheses.
f(x) = (x² -6x +9) +8 -9
Rewrite the trinomial in parentheses as a square. The constant in the binomial will be the value you squared in the previous step.
f(x) = (x -3)² -1 . . . . . vertex form; a(x -h)²+k for vertex (h, k)
__
B. The vertex and the axis of symmetry can be read from the equation. Here, the vertex is (3, -1). The axis of symmetry is the vertical line through the vertex: x = 3. The x-intercepts are found by solving f(x) = 0.
f(x) = 0
(x -3)² -1 = 0
(x -3)² = 1 . . . . . add the opposite of the 'k' value
x -3 = ±√1 . . . . take the square root. We need both signs.
x = 3 ± 1 . . . . . add 3 to get x by itself. These are the x-intercepts.
x = 3-1 = 2 and x = 3+1 = 4
The x-intercepts are 2 and 4, points (2, 0) and (4, 0).
The y-intercept is the value of f(0). It is the constant in the original form of the function. f(0) = 8 . . . . y-intercept
__
C. The graph is attached. The various points above are marked, and the axis of symmetry is shown.

Step-by-step explanation:
A bicycle shop is selling $500 bikes at 10% off. If the sales tax is 7%, how much will the bike cost?
Answer:
The bike will cost $481.50
because
10% off of 500 is 50
so 500 - 50 = 450
Now include the sales tax which is
450 * 0.07 = 31.5
Now add the two totals to get
$481.50

7x + 4 = 25, then x is equal to
a) 29/ 7 b) 100/7 c) 2 d/ 3
Answer:
d) 3
Step-by-step explanation:
7x+4=25
7x=21
X=3
Answer: D. 3
Step-by-step explanation:
Given
7x+4=25
Subtract 4 on both sides
7x+4-4=25-4
7x=21
Divide 7 on both sides
7x/7=21/7
x=3

What is the area of this composite figure??
Please help! I am so confused!
Answer:
180 cm²
Step-by-step explanation:
Area of Triangle: 1/2bh
You can divide the figure into two parts: top and bottom.
Top:
1/2(4)(12)
1/2 (48)
24
24 • 2 (two triangles) = 48 cm²
Bottom:
1/2(12)(11)
1/2 (132)
66 • 2 (two triangles) = 132 cm²
Add them up: 48 cm² + 132 cm² = 180 cm²

Nico gives himself $90 a month to spend on fast food. He spends
$30 a week. The graph represents the amount of money Nico
has left after each week.
well if he spends $30 a week the the money should last about 3 weeks. so there wold be 3 weeks worth of money each month. so you can assume that he uses $1080 a year. and he buys fast food for 36 weeks.
