An airline charges an extra fee if a carry-on bag weighs more than 30 pounds. After packing, Lorrie’s carry-on weighs 21.2 pounds. The inequality represents the amount of weight Lorrie can add to the carry-on without going over the 30-pound limit.
21.2 + w less-than-or-equal-to 30
How much weight can Lorrie add to the carry-on without going over the 30-pound limit?
Answer: No more than 8.8 pounds.
Step-by-step explanation: Let x be the weight that Lorrie can add to carry-on.
We are told that an airline charges an extra fee if a carry-on bag weighs more than 30 pounds. After packing, Lorrie’s carry-on weighs 21.2 pounds. The inequality that will represent the the amount of weight Lorrie can add to the carry-on without going over the 30-pound limit is:
Let us solve for x by subtracting 21.2 from both sides of our inequality.
We can see that the weight Lorrie can add to the carry-on should be less than or equal to 8.8 pounds without going over the 30 pound limit. Therefore, the weight that Lorrie can add to the carry-on should be no more than 8.8 pounds.
A triangle has two side lengths: 18 in and 12 in. Which of the following could be the length of the third side?
Answer:
6<L<30
Step-by-step explanation:
because we know that the third side needs to be in between the sum of the other two it has to be less than 30 and then because it needs to apply to the other sides it is greater then 18-12 or 6.

Answer:
Use tan trig ratio:
[tex]\sf tan(\theta)=\dfrac{O}{A}[/tex]
where [tex]\theta[/tex] is the angle, O is the side opposite the angle, and A is the side adjacent the angle
Given:
[tex]\theta[/tex] = 39°O = 10[tex]x[/tex] = ASubstituting these values into the formula:
[tex]\implies \tan(39)=\dfrac{10}{x}[/tex]
Multiplying both sides by [tex]x[/tex]:
[tex]\implies x\tan(39)=10[/tex]
Dividing both sides by [tex]\tan(39)[/tex] :
[tex]\implies x=\dfrac{10}{\tan(39)}[/tex]
[tex]\implies x=12.34897157...[/tex]

Two sides of an isosceles triangle have lengths 12 and 18. What
is the greatest possible value of the perimeter of the triangle?
Please help me.
The greatest possible value of the perimeter of the triangle is 48
What is the perimeter of a triangle?The perimeter of a triangle is the sum of the lengths of the three sides of the triangle.
An isosceles triangle has 2 equal sides and the length of the 2 sides must be greater than the length of one.
Perimeter A= 12×2+18=42
Perimeter B= 12+18×2=48
Therefore the greatest possible perimeter of the triangle is Perimeter B (48) since the sum of lengths of the two equal sides(18) is greater than the third side (12) and 48 is greater than 42.

A number plus nine is the same as two-fifths of nine.
Answer:
Nine more than two-fifths of a number is nine.
Step-by-step explanation:
we know that the total will be 9, and that 2/5x is equivalent to 2/5 of a number (so it should be 2/5n) and we are adding 9 more.

HELP!!! The diameter of a circular wall hanging is 4 ft. What is the area of the wall hanging to the nearest tenth? Use 3.14 for π.
A: 3.1 ft2
B: 12.6 ft2
C: 9.4 ft2
D: 6.3 ft2
Help it’s do in 5 minutes
Answer:
B
Step-by-step explanation:
Area of circle= πr²
Start by finding the radius:
Diameter= 2(radius)
4= 2(radius)
radius= 4 ÷2
radius= 2 ft
Area of circular wall hanging
= 3.14(2²)
= 3.14(4)
= 12.56
= 12.6 ft² (nearest tenth)
Thus, option B is correct.

Wanda spun a spinner 30 times, and the results were recorded in the following tally chart
Answer:
30%
Step-by-step explanation:
So she spun the spinner 30 times so we divide the number of times she got solid by the 30 to get the answer in a percentage :)
9/30 = 0.3
Now we multiply the 0.3 by 100 to get it as a percent!
0.3 x 100 = 30%
Now you know how to find the probability of an object!
Have a great day!!
Please rate and mark brainliest!!
Explanation:
Count the tally marks for the "solid" in the middle row. The first portion is a group of 5 as shown by the slash mark. The second portion of that row is one short of five, so it's another 4 tallies. Overall, we have 5+4 = 9 tallies for the "solid".
This is out of 30 spins total. Therefore, we arrive at 9/30 = (3*3)/(3*10) = 3/10
