Florencia preparó un kilo 3/4 kg de dulce de leche y quiere dividirlo en porciones iguales en 5 frascos Cuántos kg de Dulce pondrá en cada frasco A cuántos gramos equivalen
Answer:
Each jar contains 150 g.
Step-by-step explanation:
Florencia prepared a kilo 3/4 kg of dulce de leche and wants to divide it into equal portions in 5 jars How many kg of Dulce will she put in each jar How many grams are equivalent?
Amount prepared = 3/4 kg
Total number of jars = 5
The amount in each jar is given by
[tex]\frac{3}{4}\times \frac{1}{5}\\\\=\frac{3}{20} kg\\\\= \frac{3}{20}\times1000g = 150 g[/tex]
Find the value of x in x + y= 9 and x - y= 3.
6
-6
3
-3
x + y= 9 and x - y= 3
rearrange the second equation:
x - y= 3
x = 3 + y
x -3 = y
substitute y with "x-3" in the first equation and solve
x + y= 9
x + (x-3)= 9
2x -3 = 9
2x = 12
x = 6
you could also start with the first equation and substitute y in the second.
graphically speaking, it's the intersection point of to lines, at least the six-part of the point.
The sum of four consecutive numbers is two more than three times the greatest of these numbers. Find the numbers.
Answer:
9, 10, 11, 12
Step-by-step explanation:
Let the consecutive numbers be:
x, x+1, x+2, x+3
Greatest of the numbers will be: x + 3
x+x+1+x+2+x+3 = 3(x+3) + 2
4x + 6 = 3(x+4) + 2
4x + 6 = 3x + 12 + 2
4x + 6 = 3x + 14
Collect like terms
4x - 3x = 14 - 6
x = 8
x +1 = 8+ 1 = 9
x + 2 = 8 + 2 = 10
x + 3 = 8 + 3 = 11
x + 4 = 8 + 4 = 12
Be sure to show your work and solve for h:
13 = h - 18 - 5
Answer:
h = 36
Step-by-step explanation:
13 = h - 23 (subtract)
13 + 23 = h (move to the other side)
36 = h (add)

To the nearest square metre, calculate the curved surface area of the half pipe if it is 9m long? (With a radius of 2.5m)
Answer:
70.686 [tex]m^{2}[/tex]
Step-by-step explanation:
A=2πrh (area of cylinder without top or bottom)
A = 2[tex]\pi[/tex](2.5)(9)
A = 141.372
divide by two for half of pipe.
A = 70.686

In a paragraph, explain what the domain and range is for the function, and how you found your answer: f(x) = x2 + 6x - 25.
Answer:
Domain(-infinity,+infinity)
Range=f(x) >or= - 34
Step-by-step explanation:
Domain for every parabola the domain is (-infinity, +infinity) unless there are any restrictions
Range we look at the y value of the maximum point or minimum points
We find it by finding the turning point
F'(x) =2x+6
0=2x+6
-6=2x
x=-3
F(-3)=(-3)^2+6(-3)-23
=-34
So all value that exist on the f(x) must be greater or =-34

HELP PLEASE (CIRCLES) (40 points)
the line 3y - x = 5 is the tangent to a circle at the point A(1,2). (1) Find the equation of the line passing through A and the centre of the circle. The equation of another line passing through the centre of the circle is x + 3y = 15. (2) Find the equation of the circle.
Answer:
x² + (y - 5)² = 10Step-by-step explanation:
Tangent line is:
3y - x = 5 ⇒ 3y = x + 5 ⇒ y = 1/3 x + 5/3, the slope is 1/3Perpendicular line to this has a slope of -3 and passes through point (1, 2).
Its equation is:
y - 2 = -3(x - 1) ⇒ y = -3x + 3 + 2 ⇒ y = -3x + 5Using the second line passing through the center, find the coordinates of the center:
x + 3y = 15 ⇒ 3y = -x + 15 ⇒ y = -1/3x + 5Solve the system by elimination:
-3x + 5 = -1/3x + 5 ⇒ x = 0Then
y = 5The center is (0, 5) and radius is the distance from center to point (1, 2):
r² = (0 - 1)² + (5 - 2)² = 1 + 9 = 10The equation of circle:
(x - h)² + (y - k)² = r²(x - 0)² + (y - 5)² = 10 ⇒ x² + (y - 5)² = 10pls help will mark brainliest
Answer:
C
Step-by-step explanation:
The other answers have inputs (x) that have multiple outputs (y) which goes against the definition of a function. For example in answer D zero has both the outputs of 7 and 52 which can not happen in order to be a function. However outputs can have multiple inputs just not the other way around.

i need help plzzzz!!!!!! find the area
Answer:
3
Step-by-step explanation:
Area = 1/4 * √(5(5+2√5)) * a^2
Area ≈387.11
because each bag only covers 150 we need 3 bags
Answer:
area = 387 ft^2
3 bags
Step-by-step explanation:
See the picture below.
The pentagon is made up of 5 congruent triangles. One triangle is shown on the bottom right figure.
The left figure shows half of the triangle. We need to find h, the height of the triangle.
For a regular pentagon, the measure of each interior angle is
(n - 2)180/5 = 108
Half of the angle is 54 deg.
tan A = opp/adj
tan 54 = h/7.5
h = 7.5 * tan 54
h = 10.32 ft
Area of half triangle = bh/2 = 7.5 ft * 10.32 ft/2 = 38.7 ft^2
The pentagon is made up of 5 larger triangles or 10 half triangles.
Area of pentagon = 10 * 38.7 ft^2
Area of pentagon = 387 ft^2
1 bag is good for 150 ft^2.
387 ft^2/150 ft^2 = 2.6

plss answer someone the bottom question qracias
0.6(180) is the same as asking the question - What is 60% of 180?
To find that answer, we can multiply 0.6 by 180. We use the decimal 0.6 because that is the decimal form of 60%.
0.6 x 180 = 108
Another way we can find this answer is to find 1/10 of 180 and multiply this answer by 6 because 60/100 is the same thing as 6/10.
1/10 of 180 = 18
18 x 6 = 108
Hope this helps!
What is the equation of the following line?
Answer:
The equation of the line is y=7x
Which answers are written in function notation
Step-by-step explanation:
An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”; that is, y = f ( x). This last expression is read as “ y equals f of x” and means that y is a function of x.

Answer:
For this exercise, we need to add to the $200 the cost of the hours the DJ has been working
If each hour costs 12.50 $ and he worked 8.5 hours, we can just multiply to see the price of their work: 12.5 * 8.5 = $106.25
Now, we can do the sum: 200 + 106.25 = $306.25
