What is 3/4 and 7 3/4 in decimal form?

Answers

To find the decimal form of a fraction

You must divide the top number by the bottom number

3/4= 0.75

7 3/4 = 31/4 = 7.75

I hope that's help:0

3/4 in decimal form is .75 and 7 3/4 in decimal form is 7.75

Nina put together 6 squares to make a rectangle. There are 3 rows of squares. Each row has 2 squares. How many small and large squares in all are in the rectangle. Explain your answer.

Answers

Dear Bethanyawadle, you can find 8 squares, large and small. You have the six small squares total (6), and you have two large squares grouping two squares that are 2x2. (2). Add 6 and 2 to get 8 squares.

Identify the vertex, the axis of symmetry, the maximum or minimum value, and the range of the parabola.yequalsxsquaredplus2xplus1
The vertex is
nothing. (Type an ordered pair.)

Answers

Answer:

Vertex = (-1, 0)

The axis of symmetry is x = -1

Minimum point is (-1, 0)

Range is y ≥ 0

In the interval notation [0, ∞)

Step-by-step explanation:

The given function is y = x^2 +2x + 1.

Write the given equation in the form of y = (x -h)^2 + k.

Here (h,k) is the vertex.

y = x^2 + 2x + 1

y = (x + 1)^2

Vertex = (-1, 0)

Axis of symmetry

The axis of symmetry splits the parabola in 2 equal parts.

In this equation, the axis of symmetry is x = -1

Maximum/minimum value

The parabola goes maximum when there is negative sign, it goes minimum when there is positive sign.

Here we have positive sign in front of (x + 1)^2, therefore, it is minimum at

y= 0

When y =0, x = -1

Therefore, minimum point is (-1, 0)

Range

Y- axis represents the range.

Here the minimum is 0, the maximum goes upto infinity.

Range is y ≥ 0

In the interval notation [0, ∞)

Herewith I have attached the graph of the function.

Y = x^2 + 2x + 1
Convert to vertex form by completing the square
(2/2)^2 = 1
(X^2+2x+1) -1 +1
Y = (X + 1)^2
The vertex is (1,0) because we have no + q, and we have 1 as our p, and since I don’t know any of the points in order to figure out the vertical stretch, this is the final answer.

Hope this helped!!!

What times what equals 20

Answers

There can be multiple answers to this question.

20 × 1 = 20
10 × 2 = 20
5 × 4 = 20

The solution is:

1 times 20 equals 20

2 times 10 equals 20

4 times 5 equals 20

Here, we have,

given that,

we have to find what times what equals 20.

now, let the numbers be x and y

so, we get, x × y = 20

now, we know that,

the numbers that make 20 are: 1, 2, 4, 5, 10, 20

so, we get,

There can be multiple answers to this question.

as, we have,

20 × 1 = 20

10 × 2 = 20

5 × 4 = 20

Hence, The solution is:

1 times 20 equals 20

2 times 10 equals 20

4 times 5 equals 20

The sum of Sally's age plus twice Tomas's age is 12. The difference of Sally's age and Thomas's age is 3. Write and solve a system of equation to find their ages. Interpret the solution.

Answers

s=sally
tomas=t

s+2t=12
s-t=3
add t to both sides
s=3+t
subtitute 3+t for s in first equation
3+t+2t=12
3+3t=12
subtract 3
3t=9
divide by 3
t=3
tomas=3

subsitute
s=t+3
s=3+3
s=6

sally=6
tomas=3

Sally is older because:Sally:6Thomas:3Twice Thomas's age is 6.6+6=12Equation:6+3x2 or (6+3)x2 hint:PEMDASSolved:12
