xenn [34]

Answer:

15, 17, 19

Step-by-step explanation:

x + x+2 + x+4 = 15 + (x+2 + x+4)

3x + 6 = 15 + 2x + 21

x = 15

x+2 = 17

x+4 = 19

Mr. Lawrence used 100 tiles when he put a new floor in the kitchen 34 tiles are squares and 16 tiles are rectangles write the to

Oliga [24]

<h3>Fraction of square tiles = $(\frac{4}{25}) = 0.16$ </h3><h3>Fraction of rectangle tiles = $(\frac{17}{50}) = 0.34$ </h3>

Step-by-step explanation:

Total number of tiles to be used in the kitchen = 100

The total number of square tiles = 34

The total number of rectangle tiles = 16

Now, calculating the total fraction of square tiles:

The fraction of square tiles = $\frac{\textrm{Total number of square tiles}}{\textrm{Total number of tiles}} = \frac{16}{100} = \frac{4}{25}$

Also, solving the fraction, we get $\frac{4}{25} = 0.16$

So, the decimal value of square tiles = 0.6

Calculating the total fraction of rectangle tiles:

The fraction of rectangle tiles = $\frac{\textrm{Total number of rectangle tiles}}{\textrm{Total number of tiles}} = \frac{34}{100} = \frac{17}{50}$

Also, solving the fraction, we get $\frac{17}{50} = 0.34$

So, the decimal value of rectangle tiles = 0.34

Find the perimeter of the semicircle when diameter is 3.5 cm. (1 Point)

Feliz [49]

● Answer:

8.995 cm

● Step-by-step explanation:

P = d + L/2

d = 3.5 cm

L/2 = 2pi×r/2

= pi×d/2

= 3.14×3.5/2

= 5.495 cm

P = 3.5cm + 5.495

= 8.995 cm

A box contains 8 red markers, 5 green markers, and 5 blue markers. Once a marker is pulled from the box, it is replaced, and the

Andru [333]

Well. add all of these up 8+5+5. we know 5+5 is 10. and 10+8 is 18. so 18 is the denominator. There are 8 red markers and 5 blue markers at 8 and 5 up. 8+5 is 13 right? So the numerator will be 13. but the probability of picking a blue then a red is 13 alone or if you are ask for out of the amount of markers there are, its 13/18. so the probability is 13 or 13/18.
