Answer:
The inequality 7.50c - 350 ≥ 700 can be used.
Step-by-step explanation:
Given that:
Amount spent on materials = $350
Amount the council needs to earn = $700
Selling price per corsage = $7.50
Number of corsages sold = c
Selling price per corsage * Number of corsages sold - amount spent on materials ≥ amount needs to be earned
Hence,
The inequality 7.50c - 350 ≥ 700 can be used.
Answer:
Tamara incorrectly factored the whole expression.
Step-by-step explanation:
Note that
- 21x=3·7·x;
- 56xy=2·2·2·7·x·y.
Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.
Thus,
21x+56xy=7x(3+8y).
Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.
Answer: Never true.
Step-by-step explanation: Distribute the numbers: 4 times x is 4x, 4 times 3 is 12. Then you have the equation: -x+4x +12 = -12. Now, choose a random number, maybe -4. A negative plus a negative cancels out so you are left with 4-16(Because you distribute the number) +12 = -12. 4-16 is -12. -12 plus 12 equals 0.
The EXACT ratio is 7.7:1, but you can round it up to about 8:1
Answer:
Radius of tire=0.58 meter
Step-by-step explanation:
as we know that the
Circumference of the tire=2*3.14*r
and it needs to rotate 30 times to cover the street distance of 360 feet
So, the below equation would be used to find the radius of tire in the meters
360/3.28084=30*2*3.14*r
r=0.5824203822 meters
Hence
