When graphing an ordered pair, what is the second number and what does it tell you to do?

Schach [20]

The second number after the comma is the y value of the point of a coordinate grid. (x, y) It represents how far up or down the point is (controls the vertical position of the point).

Brianna has a container with a volume of 1.5 L she estimates the volume to be 2.1 m what is the percent error

Anuta_ua [19.1K]

<h3>Answer: 40%</h3>

===================================================

Work Shown:

Subtract the values to get 2.1-1.5 = 0.6

Brianna is off by 0.6 liters

Divide that error by the true value 1.5 to get 0.6/1.5 = 0.40

Then move the decimal point 2 spots to the right to arrive at 40%

Therefore, the percent error is 40%

------------------

The formula you can apply is:

$P = \frac{|G-T|}{T}*100\%$

where

P = percent error

G = guess value (in this case it is 2.1)

T = true value (which is 1.5 in this case)

If we were to apply the formula, then we get:

$P = \frac{|G-T|}{T}*100\%\\\\P = \frac{|2.1-1.5|}{1.5}*100\%\\\\P = \frac{|0.6|}{1.5}*100\%\\\\P = \frac{0.6}{1.5}*100\%\\\\P = 0.40*100\%\\\\P = 40\%\\\\$

Please help me with this

mafiozo [28]

Answer:

Step-by-step explanation:

Let:

s - side of the square

d - diameter of the circle

r - radius of a circle

C - circumeference of the circle

AC - area of the circle

AS - area of a square

The formula of a perimeter of a square:

P = 4s

We have P = 40cm.

Substitute:

4s = 40 divide both sides by 4

s = 10 cm

The length of the diameter of the circle inscribed in the square is equal to the length of the side of the square.

Therefore d = s → d = 10 cm.

The length of the circle diameter is two lengths of the circle radius.

Therefore d = 2r → r = d : 2 → r = 10 : 2 = 5 cm.

The formula of a circumference of a circle:

C = dπ.

Substitute d = 10cm, and π = 3.14.

C = 10(3.14) = 31.4 cm.

The formula of an area of a circle:

AC = πr²

Substitute r = 5cm and π = 3.14

AC = 3.14(5²) = 3.14(25) = 78.5 cm².

The formula of an area of a square:

AS = s²

Substitute s = 10 cm

AS = 10² = 100 cm²

sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 70cm and the short side is 40cm.

Strike441 [17]

Answer:

$220$ cm

Step-by-step explanation:

We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be $2(l+w)$ , where $l$ is the rectangle's length and $w$ is the rectangle's width. We are given that $l=70$ and $w=40$ . Therefore, $2(70+40)=2*110=220$ cm of ribbon will be needed. Hope this helps!
