Answer:
36.8 or 37 yards of fabric
Step-by-step explanation:
23 yards of fabric = five dresses
23 divided by five equals four point six
four point six multiplied by eight dress equals 36.8
23 yds of fabric = 5 dresses
23÷5=4.6
If you need to know how many yards of fabric, then you'd do:
4.6×8
4.6 is the amount of each yards 5 dresses are in and so if you times that by how many dresses you need now, you'll get:
36.8 yards of fabric
To round, it'd be 37 yards of fabric
Answer:
no
Step-by-step explanation:
this is because when dealing with the power, it involves multiplication
Answer: y>-3 and x is all real numbers
Answer:
1/50* 1/2 =0 .01
Step-by-step explanation:
First, the probability that the spinner lands on 20 is
1
/50
, as 20 is one of the 50 numbers on the wheel, and each number has an equal probability of being selected.
Second, the probability that the spinner lands on an odd number is
1/2
. This is because of the 50 numbers on the wheel, half are even and half are odd.
Answer:
13 is the number.
Step-by-step explanation:
Given:
Twice the difference of a number and 9 equals 8.
Let the unknown number be 'x'.
Therefore, as per question:
The difference of 'x' and 9 = ![x-9](https://tex.z-dn.net/?f=x-9)
Twice the difference means 2 times the difference. So, we multiply 2 to the difference. Therefore,
![2(x-9)](https://tex.z-dn.net/?f=2%28x-9%29)
Now, the above expression is equal to 8. So, we equate the above expression to 8. This gives,
![2(x-9)=8](https://tex.z-dn.net/?f=2%28x-9%29%3D8)
Solving for 'x', we get:
Using distributive property of addition and distributing 2 inside the bracket. This gives,
![2\times x-2\times 9=8\\\\2x-18=8\\\\2x=8+18\\\\2x=26\\\\x=\frac{26}{2}=13](https://tex.z-dn.net/?f=2%5Ctimes%20x-2%5Ctimes%209%3D8%5C%5C%5C%5C2x-18%3D8%5C%5C%5C%5C2x%3D8%2B18%5C%5C%5C%5C2x%3D26%5C%5C%5C%5Cx%3D%5Cfrac%7B26%7D%7B2%7D%3D13)
Therefore, the unknown number is 13.
Now, we can verify our answer.
![2(13-9)=26-18=8](https://tex.z-dn.net/?f=2%2813-9%29%3D26-18%3D8)
Therefore, the answer is correct.
