Step-by-step explanation:

At the end of the 2 week, both Mary and Ardella has an equal amount of saving i.e. $140.

Mary and Ardella are saving money for a trip. Mary started her savings with $20 and is now saving $12 each week. Ardella started her savings with $40 and is now saving $10 each week. After how many weeks will Mary and Ardella have saved the same amount of money To determine,

In mathematics, it deals with numbers of operations according to the statements.

Let the number of weeks is x and total saving is y.
Now equation for Mary started her savings with $20 and is now saving $12 each week.
y = 12x +20 - - - (1)

The equation for Ardella, started her savings with $40 and is now saving $10 each week.
y = 10x + 40   - - - - (2)

Equating equation 1 and 2
12x +20 = 10x +40
12x -10x = 40 -20
2x = 20
x = 20/2
x = 10

Now put this x in equation 1
y = 12 * 10 + 20
y = 140

Thus, at the end of the 2 week both Mary and Ardella has an equal amount of saving i.e. $140.

Answer:

slope - 1  y int - (0,0)

Step-by-step explanation:

to find the y intercept you go to where x equal 0 and when x equals 0 y also equals 0 so the y intercept is (0,0)

the slope is change in y over change in x and as y goes up 1 x goes up 1 1/1=1 so the slope is 1

where B and C are the base and height of the triangle, respectively.

I take it as you want to learn about the formula.

The quadratic formula is a formula where you can solve x for any quadratic equation in form  ax^2+bx+c=0.

The formula is x= [tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex].

The +- means + or - for the 2 solution in each equation.

*All above information is what you need to know about the quadratic formula and solve for answer, but I will go a step further in my answer to prove the quadratic formula always work.

[tex]0=ax^2+bx+c[/tex]

[tex]0=(ax+\frac{b}{2})^2-\frac{b^2}{4}+c[/tex] (This step is completing the square)

[tex](ax+\frac{b}{2})^2=\frac{b^2}{4}-c[/tex]

[tex](2ax+b)^2=b^2-4ac[/tex]

[tex]2ax+b=+or-\sqrt{b^2-4ac}[/tex]

[tex]2ax=-b+ or -\sqrt{b^2-4ac}[/tex]

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

This is my way of proving this formula although there are many other ways to do it too, if there is any questions, feel free to ask me in the comment :-).

Answer:

the answer is 6.75

Step-by-step explanation:

12 x 5 = 60 60 = 1 hour so 1.35 x 5 = 6.75

The running speed is 8.1 miles/ second.

Speed is the rate at which something is covering a distance in a fixed period of time.

It is measured in miles/ min or miles/sec.

It is given that

Speed = 1.35 miles per minute

1 minute = (1/60) hour

Therefore the speed = 1.35 *60

Speed = 8.1 miles/second

Therefore the speed is 8.1 miles/ second.

Answer: y = 11.25

Step-by-step explanation:

Mi espanol es terrible :l

Todos los angulos terminaran acompletando 90° grados

Entonces hagamos una ecuacion

3y + 4y + y = 90

8y = 90

Divide por 8

y = 11.25

Para ver si es verdad hagamos el math

3(11.25) = 33.75

4(11.25) = 45

y = 11.25

33.75 + 45 + 11.25 = 90

Answer:

Each red block has an area of     1/18     square unit.

2/3 * 5/6  = 2/3 * 5/6 = 10/18

Step-by-step explanation:

The area of each red rectangle block is 1/12 sq units.

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral. Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.

Given that, there is rectangular box, in which there are 24 blocks,

The area of the rectangular box is 2 sq units,

We need to find the area of each block,

We can say,

24 blocks = 2 sq units

1 block = 2/24 = 1/12 units

Since, all the blocks inside the box are identical, therefore, each red block will also have area = 1/12 units

Hence, the area of each red rectangle block is 1/12 sq units.

Step-by-step explanation:

Answer:

18 tablespoons of blue paint; 3 batches

Step-by-step explanation:

For 1 batch of paint, she uses 2 cups of white paint and 6 tablespoons of blue paint.

She needs to mix blue paint using 6 cups of white paint.

6 cups is 3 times 2 cups, so she will be making 3 batches.

She also needs to use 3 times the amount of blue paint that she would use for 1 batch.

Since she uses 6 tablespoons of blue paint in 1 batch, she needs to use 3 times as much blue paint.

3 * 6 tablespoons = 18 tablespoons.

Answer:

15/14

Step-by-step explanation:

I am assuming you meant. 3(x+1/2)

10x-6=3x+3/2

7x=3/2+12/2

7x=15/2

x=15/2*1/7

x=15/14

The value of x from the given equation is 15/14.

The given equation is 10x-6=3(x+1/2)

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows

10x-6=3x+3/2

⇒ 10x-3x=3/2 +6

⇒ 7x = (3+12)/2

⇒ 7x = 15/2

⇒ x=15/14

Hence, the value of x from the given equation is 15/14.

Givens

angle = 27

opposite side = 18

hypotenuse = ?

Solution

Sin(27) = opposite side / hypotenuse

Sin(27) = 18 / hypotenuse                         Multiply by the hypotenuse

hypotenuse * sin(27) = 18                         Divide by sin(27)

hypotenuse = 18 / sin(27)

hypotenuse = 18 / 0.45699

This is a very difficult question to pick an answer for. Everything depends on what you have been told about 5 when rounding. I always use a very simple method. It the rounded number is a 5 then you bounce the answer up. Otherwise leave it alone.

I think the correct answer (according to my rule) is that the answer is C, but your teacher could actually use a rule which would round it up to 39.7. I'm going to answer C but if you get it wrong, then D is the answer.
