2.25(14.3m + 6 + 2.7m)

Answer:

Below in bold.

Step-by-step explanation:

10x² + 3x -2 = -1

10x^2 + 3x  - 1 = 0            Taking 10 out from the first 2 terms:-

10(x^2 + 0.3) - 1 = 0           Completing the square:

10[(x + 0.15)^2 - 0.15^2] - 1 = 0

10[(x + 0.15)^2 - 0.0225] - 1 = 0

10(x + 0.15)^2 - 0.225 - 1 = 0

10(x + 0.15)^2 - 1.225 = 0  is vertex form.

The vertex (turning point is at (-0.15, -1.225).

y- intercept is at the point where x = 0,

- that is at y = 10(0.15)^2 - 1.225 = -1

So at (0, -1).

Solving for x:

10(x + 0.15)^2 - 1.225 = 0

(x + 0.15)^2 = 0.1225

x + 0.15 = +/- sqrt 0.1225

x = -0.15 +/- sqrt 0.1225

The roots are  -0.5, 0.2

C is the answer. Hope it helps

Answer: Red ribbon.

Step-by-step explanation:

When it comes to fractions, if all the fractions being compared have the same numerator, the fraction with the smallest denominator is the largest.

In this question, all the fractions have a numerator of 1 so the longest one will be the one with the smallest denominator which is 1/3. The red ribbon is the longest.

Another way is to convert them to percentages:

1/6 * 100% = 16.7%

1/3 * 100% = 33.3%

1/4 * 100% = 25%

Red ribbon is again the largest.

Answer:

x=−y+1

Step-by-step explanation:

Let's solve for x.

4x+4y=4

Step 1: Add -4y to both sides.

4x+4y+−4y=4+−4y

4x=−4y+4

Step 2: Divide both sides by 4.

4x        =    −4y+4

4          =        4

x=−y+1

Answer:

Selling price : $52

Step-by-step explanation:

First, find 30% out of 40.

x= (40)(30)=1200/ 100= 12

x=12

Add 30% to the original selling price.

So then you add $12 to $40 to get $52.

Answer: 32 and 42

Step-by-step explanation:

5j +12

j= 4

j = 6

5(4) + 12

5 times 4 = 20

20 + 12 = 32

5(6) + 12

5 times 6 = 30

30 + 12 = 42

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Answer:

the answer is d

Step-by-step explanation:

we can use point-slope form to find this answer.

first, make this equation

y-y 1=m(x-x1)

y-4=-6(x-1)

m=-6 because you can use slope intercept form to find the slope (as the name states lol)

then just distribute!!

y-4=-6x+6

add four to both sides

y=-6x+10

whoops, i did a little too much the answer is in bold!!!

good luck!! hope this helped! <3

Step-by-step explanation:

Answer:

Yes you have enough money because with the dicound the crocs are $45.50

Step-by-step explanation:

u have $50 the crocs is $65 but have 30% off

$65 with 30% off is $45.50

Answer:

YAY, you can buy the Crocs!

Step-by-step explanation:

First we divide $65/100% to find one percent.

1% = 0.65

100% (original price) - 30% (sale) = 70% --> so the Crocs cost 70% their original price.

0.65 (1%) x 70 = $45.50 (final price of Crocs)

Answer:

In order to get the number of hours spent by the students on homework, a survey would be conducted where information would be collected from the students.

Step-by-step explanation:

In order to acquire the information directly from the users which cannot be measured otherwise, surveys are the best option. These provide an appropriate way of reaching out to large masses at a small-time with little or no prior investment.

Answer:

Volume of the cylinder is 588π cm³ Or 1846.32 cm³

Step-by-step explanation:

Area of a cylinder is given by the formula,

Volume = πr²h

Here, r = Radius of the circular base

h = Height of the cylinder

From the picture attached,

Radius of the given cylinder = 7 cm

Height of the cylinder = 12 cm

By substituting these values in the formula,

Volume of the cylinder = π(7)²(12)

                                      = 588π cm³

                                      ≈ 1846.32 cm³

Therefore, volume of the cylinder is 588π cm³ Or 1846.32 cm³.
