Answer:
Option B is correct.
Step-by-step explanation:
Total bill = $48
Tip = 20%
Amount of tip = 20% of 48
Amount = [tex]\frac{20}{100}*48[/tex]
Amount = 0.2 * 48
Amount = $9.60
Total bill with tip = 48 + 9.60 = $57.60
Dividing by 2 as they are spliting the bill.
Each pays = [tex]\frac{57.60}{2}=28.80[/tex]
Therefore,
Option B is correct.

Answer:
124.8 and 39.6
Step-by-step explanation:
120 * .04 = 4.8
it says to increase so 120 + 4.8 = 124.8
45 * .12 = 5.4
it says to decrease so 45 - 5.4 = 39.6
Select all the inequalities that relate the sides of the figure shown.

c>a
c
b>a
a
Answer:
b
Step-by-step explanation:
According to the given angles in the question, angle b is greater than angle a.
What is inequality?Mathematical equations with inequalities on both sides are known as inequalities. In an inequality, we compare these two values as opposed to equations. Somewhere between, the equal sign is changed to a less than (or less than or similar to), bigger than (or greater or equal to), or just not equal to sign.
As per the given data from the question,
The side which has got a larger angle has the largest side.
The side c is greater than a and side b is also greater than a.
The remaining angle can be calculated as:
The sum of all angles will be equal to 360.
x + 75 + 90 + 105 = 360
x = 90°.

Which is true about quadrant equations
Answer: In algebra, a quadratic equation (from the Latin quadratus for " square ") is any equation having the form where x represents an unknown, and a, b, and c represent known numbers, with a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Hey there !!!
the question is incomplete the full question is Which of the following statements is TRUE/CORRECT about Quadratic Equations? A quadratic equation is _____
with options
A) an expression with a single variable and degree 2
B) an equation with a single variable and degree 2
c) an equation with only degree to 2
D) an equation with single variable only
and the correct answer is B
because Quadratic Equation states that An equation with one variable and degree 2 is a Quadratic Equation. Only option b satisfies the two basic conditions of a quadratic equation i.e. one/single variable and degree 2. Hence b is the correct answer.

D
Answer:
x = 20°
Step-by-step explanation:
An equilateral triangle has three equal angles of 60° each.
Since ∆BCD is an equilateral triangle, it follows that:
<CBD = <BCD = <CDB = 60°
m<ACD = 40° + <BCD
m<ACD = 40° + 60° (substitution)
m<ACD = 100°
x + m<ACD + CDB = 180° (sum of triangle)
x + 100° + 60° = 180° (substitution)
x + 160 = 180
Subtract 160 from each side
x = 180 - 160
x = 20°

Answer:
ok so you first point is the y intercept =5 plot this at 5 on the y axis/vertical line from there you plot your slope =1/2 you go up 1 and over 2
Answer: you calculate where the points are and place them in the coordinated spots
Step-by-step explanation:
When looking at coordinates, the first number is on the x axis(horizontal/ side to side line) and the second in on the y axis(vertical/ up and down line) then counting the lines of the point over to the given x axis number, then up the given y axis number
What is m∠DEF?
Enter your answer in the box.
There is a triangle DEF in which side DE is congruent to side EF and G is the midpoint of the side DF. Segment EG intersect the side DF at point G. The measure of angle DEG is (3y+4) degrees and the measure of angle FEG is (5y-10) degrees.
Answer:
m<DEF = 8y - 6
Step-by-step explanation:
Given that: DEG = [tex](3y +4)^{o}[/tex], and FEG = [tex](5y-10)^{o}[/tex].
The given triangle is an isosceles triangle with sides DE ≅ DF.
But,
m<DEF = DEG + FEG
= [tex](3y +4)^{o}[/tex] + [tex](5y-10)^{o}[/tex]
= 3y + 4 + 5y - 10
= 8y - 6
m<DEF = 8y - 6
Therefore, the measure of < DEF is 8y - 6.

Definition of equilateral triangle
Answer:
An equilateral triangle has all its 3 angles the same.
Hope this helped. :)
Equilateral triangle:
An equilateral triangle is a triangle having three equal sides, or what is sometimes referred to as a "regular" triangle. Because all three sides of an isosceles triangle are equal, an equilateral triangle is a particular case of an isosceles triangle.
Additionally, an equilateral triangle has three equal angles of 60 degrees.
Equilateral Triangle Perimeter:
In geometry, any polygon's perimeter is equal to the sum of its sides. The perimeter of an equilateral triangle is equal to the sum of its three sides.
In the event that ABC is an equilateral triangle, then its perimeter is;
Perimeter = AB + BC + AC
P = a + a + a
P = 3a [where "a" is the triangle's side length.]

y = 3^xRaquel and her brother Marcus are huge sports fans. Combined they own 15 sports jerseys. Raquel owns double the amount of Marcus's jerseys plus an additional three. Use x to represent Marcus's amount of jerseys and y to represent Raquel's amount of jerseys.
Answer:
[tex]x = 4[/tex] -- Marcus
[tex]y = 11[/tex] -- Raquel
Step-by-step explanation:
Given
[tex]x =Marcus[/tex]
[tex]y = Raquel[/tex]
[tex]x + y = 15[/tex] -- Both
[tex]y = 2x + 3[/tex] -- Raquel
Required
Determine x and y
Substitute 2x + 3 for y in [tex]x + y = 15[/tex]
[tex]x + 2x + 3 = 15[/tex]
[tex]3x + 3 = 15[/tex]
Collect Like Terms
[tex]3x = 15-3[/tex]
[tex]3x = 12[/tex]
Divide both sides by 3
[tex]x = 4[/tex]
Substitute 4 for x in
[tex]y = 2x + 3[/tex]
[tex]y = 2 * 4 + 3[/tex]
[tex]y = 8 + 3[/tex]
[tex]y = 11[/tex]
