Jessica went to dinner and her bill was $15.60. If she wants to leave a 15% tip, how much is the tip? How much did she spend total after the tip?
Answer:
A) $2.34
B) $17.94
Step-by-step explanation:
First in order to find the tip you need to set up a proportion:
15/100 = x/15.6
Step 1: Cross-multiply.
15/100 = x/15.6
(15)*(15.6) = x*(100)
234 = 100x
Step 2: Flip the equation.
100x=234
Step 3: Divide both sides by 100.
100x/100 = 234/100
x = 117/50 (2.34)
The tip is $2.34
Now to find the total, add the tip to the bill.
15.6+2.34
= 17.94
The total bill was $17.94

Find the value of x in each diagram.
Answer:
4. 25 5. 80 6. 30
Step-by-step explanation:
All triangles add up to 180.
The triangle in #4 is right, so 90° + 65° = 155°
180° - 155° = 25°
x=25
#5.
50° + 50° = 100°
180° - 100° = 80°
x=80
In #4 the triangle is an equilateral, so all the angles will be equal. 2x + 2x + 2x = 180
6x = 180
x = 30
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
Two of the angle measures are given in each triangle so to find the third angle measurement we need to subtract the sum of two of the interior angles
4.
180 - (65 + 90) = x
180 - 155 = x
25 = x
5.
180 - (50+5) = x
180 - 100 = x
80 = x
For the 6th question all side lengths are equal so the angle measures also equal and 60 each
2x = 60
x = 30

Yan na sagut ko sa module
Sana makatulong
follow me for more math answer
Answer:
3 4/5
Step-by-step explanation:
7 3/10 - 3 9/10=
In this case 3/10 - 9/10 is cannot be so we have to borrow 1 whole from 7
so, 7 3/10 will become 7 3/10 + 1 or to add we have to change 1 as 10/10, any way 1 and 10/10 is equal but in this case we will use 10/10 to add 1 whole to 3/10 and minus 1 whole to 7
so, 3/10 + 10/10 = 13/10
and 7 - 1 = 6
so, 7 3/10 as 6 13/10
any way 7 3/10 and 6 13/10 is equal but, in this case we have to use 6 13/10 to minus, because 7 3/10 is cannot be
so, 6 13/10 - 3 9/10 =
=3 4/10 or 3 2/5

Answer:
A = 81
Step-by-step explanation:
When there is a number above the other. You will need to multiply it.
There is a 4 so its 4 times.
-3 x -3 = 9
9 x -3 = -27
-27 x -3 = 81
------
When you multiply a negative number by a negative number it will be a positive.
If you multiply a positive number by a negative it will be negative.

the arrow always points to the smallest side
D) the opening of the arrow is always on the smallest side.
Answer:
C) the arrow always points to the smaller side
Step-by-step explanation:
if you struggle to remember think of it as a crocodile going for the highest amount of 'food', in this case the food is the number
Answer: C, the arrow always points to the smallest side.
Step-by-step explanation:
A way of remembering which way the '>' sign goes is to think of it as a crocodile mouth (the open bit) and the crocodile wants the most food (the biggest number).

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

major arc BRA is 3/2 the length of minor arc BSA. the length of major arc BRA is 6pi centimeters. what is the radius of the circle?
9514 1404 393
Answer:
5 cm
Step-by-step explanation:
The given arcs have the ratio ...
BRA : BSA = (3/2) : 1 = 3 : 2
Then BRA is 3/(3+2) = 0.6 of the total circumference of the circle.
0.6(2πr) = 6π . . . . . BRA is 6π long
r = 6π/(1.2π) . . . . . . divide by the coefficient of r
r = 5 . . . . centimeters

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
