Answer:

The probability of picking a purple marble and spinning green is $\frac{3}{28}$ .

Step-by-step explanation:

Since there are 7 marbles and 8 possible tiles to spin, the total amount of possible outcomes are 56. Out of the 56 different outcomes, 6 of them meet the requirement of picking a purple marble and spinning green, so the fraction to represent the situation is $\frac{6}{56}$ or $\frac{3}{28}$ .

Can someone please help me?

Answer:

2. x = 3

3. x = 10 and y =2

Step-by-step explanation:

From inspection, we can see that EF = 10 and KL = 5

Therefore the ratio KL : EF = 5 : 10 = 5/10 = 1/2

This means that the side measures of ΔJKL are 1/2 the corresponding side measures of ΔGEF

Therefore, if GF = 22, then JL = 22 ÷ 2 = 11

So: 2x + 5 = 11

⇒ 2x = 11 - 5 = 6

⇒ x = 6 ÷ 2 = 3

x = 3

From inspection, we can see that DF = 12 and HJ = 9

Therefore the ratio DF : HJ = 12 : 9 = 12/9 = 4/3

This means that the side measures of ΔDEF are 4/3 times the corresponding side measures of ΔHGJ

Therefore, if HG = 6, then DE = 6 x 4/3 = 8

So: 2y + 4 = 8

⇒ 2y = 8 - 4 = 4

⇒ y = 4 ÷ 2 = 2

y = 2

Similarly, if GJ = 24, then EF = 24 x 4/3 = 32

So: 4x - 8 = 32

⇒ 4x = 32 + 8 = 40

⇒ x = 40 ÷ 4 = 10

x = 10

Marta is making two different charms for necklace one charm has a 1 cm diameter and a 3.14 cm circumference of a similar charm h

EastWind [94]

From what I can pick up from your problem statement, you want to know "<span>a similar charm has a diameter of 4 cm what is the circumference." Please, would you use proper punctuation in your writing, for greater clarity:

"A</span><span> similar charm has a diameter of 4 cm. What is the circumference?"

The formula for the circumference of a circle, when the diameter is known, is

C=</span> $\pi$ d or C=pi*d

In this case, with diamter 4 cm, the circumference, C, is 4pi cm.
