In a box containing 20 cans, 12 of the cans contain vegetables. In the box, 5 of the cans are dented, with 2 of the dented cans containing
vegetables
What is the probability that a randomly selected can in the box is dented or contains vegetables?
OA 65%
OB. 75%
OC. 95%
OD 85%
Answer: B.) 75%
Step-by-step explanation:
12 cans contain veggies and 5 cans are dented, since two of the dented cans contain veggies don't count those two. This means you'll add 12 and 3 which equals 15. 15 out of 20 is an example of three fourths or 75%.

What is the value of n in the equation 3n + 2(n + 2) = 9n + 12? (4 points)
a. −4
b. −2
c. 2
d. 4
Can someone please give me a step by step I am really struggling <3
Answer: n = -2
Step-by-step explanation:
3n +2(n + 2) = 9n + 12
(simplify 2(n + 2)) =
3n + 2n + 4 = 9n + 12
(subtract 9n from both sides)
3n + 2n - 9n + 4 = 12
-4n + 4 = 12
(subtract 4 from both sides)
-4n = 8
(divide -4 from both sides)
n = -2

Answer:
$207.66
Step-by-step explanation:
30% off is the same as saying there is 70% not off, and 70% is the same as 0.70
0.70*349= 244.30
15% off is the same as saying 85% is not off, and
85% is the same as 0.85
0.85*244.30=207.655
because it's money, you round to 2nd decimal place

if x+x-¹ = 11, evaluate x²+x-²
A. 119
B. 120
C. 121
D. 122
no spam answers please and kindly explain ur answer.
Given x+x-¹ = 11
now square both the side
(x+x-¹)² = 11²
now open the bracket of RHS and apply (a+b)²
you'll get,
x²+2x/x+ 1/x² =121
simplify above equation you'll get,
x²+ 2 + x-² = 121
shift the equation,
x² + x-² = 121 - 2
x² + x-² = 119 !
There are two numbers, one is 7 more than twice the other. The sum of the numbers is 43. Make the equation to find the smaller number. Find the two numbers. Answer: If the smaller number is x, the equation will be . The numbers in ascending order are:
BRAINLIEST IF CORRECT
Answer:
Smaller number: 12
Greater number: 31
Step-by-step explanation:
Hi there!
Let x equal to the smaller number.
Let y be equal to the greater number.
1) Translate the information into equations
"One is 7 more than twice the other"
⇒ [tex]y=2x+7[/tex]
"The sum of the numbers is 43"
⇒ [tex]x+y=43[/tex]
2) Use substitution to solve for the smaller number
[tex]x+y=43[/tex]
Plug the equation [tex]y=2x+7[/tex] into the above equation
[tex]x+(2x+7)=43\\x+2x+7=43\\3x+7=43[/tex]
Subtract both sides by 7
[tex]3x+7-7=43-7\\3x=36[/tex]
Divide both sides by 3 to isolate x
[tex]\frac{3x}{3} = \frac{36}{3} \\x=12[/tex]
Therefore, the smaller number equates to 12.
3) Use substitution to solve for the greater number
[tex]x+y=43[/tex]
Plug in x as 12
[tex]12+y=43[/tex]
Subtract both sides by 12 to isolate y
[tex]12+y-12=43-12\\y=31[/tex]
Therefore, the greater number equates to 31.
I hope this helps!

-(7*3)*(-2) = -(21)*(-2) = (-21)*(-2) = +(21*2) = +42
b) -4*( + 3 - 2 + 5)
= (-4)*(3) + (-4)*(-2) + (-4)*(5)
= - 12 + 8 - 20 = 8 - 32 = -24

Statement 1 and statement 3 contradict
======================================================
Explanation:
We'll start with statement 1 and try to build to statement 3, and you'll find that a contradiction happens.
If angle 1 and angle 2 are supplementary, then that must mean [tex]m \angle 1 + m \angle 2 = 180[/tex] because the angles can be combined to form a straight angle.
Add the measure of angle 3 to both sides
[tex]m \angle 1 + m \angle 2 = 180\\\\m \angle 1 + m \angle 2+m\angle 3 = 180+m\angle 3[/tex]
The left side matches with the left side in statement 3, but the right side is a bit off. That [tex]m\angle 3[/tex] term needs to be zero, so that the right side boils down to simply 180. However, statement 3 specifically mentions that angle 3 is nonzero. So angle 3 is some positive value.
That's why choice C is the answer.
------------------
Here's an example:
Let's say angles 1 and 2 are 50 and 130 degrees. The order doesn't really matter, but I'll make angle 1 to be the smaller angle.
This means,
[tex]m \angle 1 + m \angle 2 = 180\\\\50 + 130 = 180\\\\[/tex]
So we've made statement 1 to be true. The angles 50 and 130 are indeed supplementary.
Now let's add some nonzero value to both sides. This will represent the measure of angle 3. If we add say 10 degrees to both sides, then,
[tex]50 + 130 = 180\\\\50 + 130+10 = 180+10\\\\50 + 130+10 = 190\\\\m\angle 1 + m\angle 2 + m\angle 3 = 190\\\\[/tex]
we don't get 180 like we want in the equation of statement 3. This is where the contradiction happens, more or less. One right side is 180, the other right side is 190. The 190 will change if you use some other value for angle 3, but hopefully you can see that it's impossible to add up angles 1 through 3 to get 180. It's only possible if angle 3 were zero degrees.
We can think of it like angles 1 and 2 hog up all the oxygen, and use up 180 points of it, leaving no air for angle 3 to breathe so that's why angle 3 must be 0. Furthermore, it means that a triangle is not possible if exactly two angles are supplementary.
----------------------
Extra info:
Statements 1 and 2 can coexist just fine without any contradictions happening. If angle 1 is 110 degrees, then that makes angle 2 to be 70 degrees (110+70 = 180). That rules out choice A.Statements 2 and 3 are just fine as well, for similar reasoning as above. We can plug in 110 for angle 1, then subtract that from 180 to get 180-110 = 70. Then from here, just ensure that angles 2 and 3 add to 70. So there are infinitely many ways to do this. Choice B can be ruled out.Choice D is ruled out because we found choice C to be the answer, ie the contradicting two statements.Answer:
C) l and lll
Step-by-step explanation:
m∠1+∠2=180
m∠1+m∠2+m∠3=180
180+m∠3=180
m∠3=0 but m∠3=∦0

Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
12, 6, 3, ...
Answer:
The sequence is geometric
The common ratio is 0.5
Step-by-step explanation:
In the arithmetic sequence, there is a common difference between each two consecutive terms
In the geometric sequence, there is a common ratio between each two consecutive terms
Let us check the given sequence
∵ The first 3 terms are 12, 6, 3
∵ 6 - 12 = -6
∵ 3 - 6 = -3
∵ There is no common difference between the consecutive terms
∴ The sequence is not an arithmetic sequence
∵ 6 ÷ 12 = 0.5
∵ 3 ÷ 6 = 0.5
∴ There is a common ratio between each two consecutive terms
∴ The sequence is a geometric sequence
∴ The common ratio is 0.5

I need answer ASAP
No links please
Answer:
The answer is B
Step-by-step explanation:
Since we already know that angle A and D are congruent, if angles C and F were also congruent, we can prove the triangles are similar through AA, meaning the triangles have 2 sets of corresponding congruent angles. The other option D doesn’t work because if we were going off on using the sides as a way to prove similarly, than all 3 sides of one triangle would need to be proportional and corresponding to the other 3 of the other triangle (which is not given, so that info isn’t enough, option D only gives us 2 sides of each triangle)

The three inside angles (A,B and C) of a right-angled triangle are in the ratio 7:18:11. Th smallest angle is 35. Work out angles A, B and C
Answer:
<A = 35degrees
<B =90degrees
<C = 55degrees
Step-by-step explanation:
Given the ratios of a triangle as 7:18:11
Total ratio = 7+18+11
Total ratio = 36
Since the smallest angle is 35degrees, hence <A = 35degrees
Get angle B;
<B = 18/36 * 180 (sum of angle in a triangle is 180degrees)
<B = 1/2 * 180
<B = 90degrees
Get angle C;
<C = 11/36 * 180
<C = 11 * 5
<C = 55degrees
Hence the value of A, B and C are 35, 90 and 55 degrees repectively
