if a = 5, what is a +6?
Answer:
B.11 correct
Step-by-step explanation:
a=5
a+6
5+6=11
11 is the correct answer so B.11 is correct
Answer:
11
Step-by-step explanation:
If a=5 and there is a+6 you need to plug in the 5 from the a=5 in the equation a+6 to get 5+6 which equals 11 :D

What is measurement angle B?
Answer: 80 degrees
Step-by-step explanation:
Answer:
B = 54 to the nearest degree.
Step-by-step explanation:
Remark
This is a sine law question. They can be rather nasty because no answer or 2 answers are possible. This one is well behaved because B, you are told, is acute. The two answer kind needs the supplement of an acute angle.
Sorry this blabs on and shouldn't. You are looking for <B
Formula
Sin(<B)/the side opposite = Sin(<A) / side opposite it
Simplified
Sin(<B) / 9 = Sin(A)/11
Sin(<B) / 9 = Sin(80) / 11 Multiply both sides by 9
9*Sin(B) / 9 = 9 * Sin(80) /11 The 9s Cancel
Now all you need to do is put it in your calculator. Do you need the steps?
Sin(B) = 9*sin(80) / 11
Sin(B) = 9 * 0.9848 /11
Sin(B)= 0.8058
B = Sin-1(0.8058)
B = 53.68
B = 54
1. A ball is kicked up from a platform 36 feet above the ground. The height of
the ball h(t) above the ground (measured in feet) can be modeled by the
function h (t)
-3t2 + 12t + 36, where t represents the amount of time
(in seconds) since the ball was kicked. How long to the nearest second did it
take the ball to hit the ground?
-
seconds to hit the ground
Answer:6
Step-by-step explanation:
So when the ball hits the ground -3t^2+12t+36 must equal 0
So you can factor a -3 out
-3(t^2-4t-12)=0
Factor -3(t-6)(t+2)=0
T-6=0 t+2=0
T=6 t=Negative 2
And since time can’t be negative the answer is 6

I need helppp!! This is confusing !
Answer:
9
Step-by-step explanation:
So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines
and A to B and D to C have two arrows meaning those two lines are the same
so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9
Hopefully this wasn't too confusing
Answer:
mCD = 9
Step-by-step explanation:
Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:
AB ║ DC
BC ║ AD
Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.
This also means that because AB = 9 and AB = DC, DC = 9.
Here's a mini two-column proof:
Statements → Reasons
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
mAB = 9 → Given
AB ║ DC, BC ║ AD → Given
ABCD is a parallelogram → Definition of a Parallelogram
AB ≅ DC → Opposite sides of a parallelogram are congruent.
mAB = mDC → Definition of Congruent Segments
9 = mDC → Substitution Property of Equality
mCD = mDC → Reflexive Property of Equality
mCD = 9 → Substitution Property of Equality

what is -2 x 3 i do not understand this and this is my last problem
Answer:
-6
Step-by-step explanation:
if they were both positive numbers, it would be 6. But when you multiply a negative by a positive, the answer is negative.
Answer:
-6
Step-by-step explanation:
When you multiply a positive number by another positive number, you will always get a positive number as your answer. Same thing for negative. If you multiply a negative by a negative, you will always get a positive. However, when you multiply a negative by a positive, you will always get a negative number.
Since you know this, you can multiply 2 by 3, which is 6. Because 2 is negative and 3 is positive, you know that the answer must be negative. Therefore, you add the negative symbol to 6, giving you -6.
I hope this isn't too confusing. Please let me know if you have any more questions. Good luck!

Answer:
x=115
Step-by-step explanation:
Straight angle = 180 degrees...
65 is accounted for so...
180-65=115
115 degrees is your final answer :)
Answer:
115
Step-by-step explanation:
x° = 180° - 65°
(Linear pair angles)
x° = 115°
x = 115

A scale drawing of a rectangle painting is 12 inches long and 8 inches tall. The actual painting is 12 feet tall. What is the scale of the drawing? What is the perimeter of the actual painting? What is the area of the actual painting?
Answer:
x = 18
Step-by-step explanation:
[tex]\frac{8}{12} = \frac{12}{x}[/tex]
then cross-multiply8x = 12 * 12
8x = 144
[tex]\frac{8x}{8} = \frac{144}{8}[/tex]
x = 18
