A clothing store purchases T-shirts for
$4.00 each and then marks up the price
of each by 55%. What is the markup and
new price of each T-shirt?
Answer:
The mark up is $2.20 and the new price of each T-shirt is $6.20.
Step-by-step explanation:
Before we find the new price of each T-shirt we must find the markup (by how much were raising the price).
The problem states each T-shirt costs $4.00, but then marks up the price of each by 55%.
Step 1 would be to find 55% of $4.00.
0.55 * 4 = 2.2
So that is the mark up, the price is going up by $2.20. To find the new price of each T-shirt, you take that $2.20 and add it to the original $4.00.
$4.00 + $2.20 = $6.20
So the mark up is $2.20 and the new price of each T-shirt is $6.20.
6 PERSONAS DEBEN VIAJAR EN UN AUTO DE 7 PASAJEROS. PERO SOLO 3 SABEN MANEJAR, DE CUANTAS MANERAS DIFERENTES SE PUEDEN ACOMODAR?
Answer:
3C1 * 7C6 * 3C2 * 3C3
Step-by-step explanation:
Dado que solo tres saben cómo conducir, de estos tres uno estará en la posición de conducción, por lo tanto, el número de formas en que este conductor puede elegir entre estos tres es 3C1 * 7C6
Ahora, 2 de los conductores se sentarán en los asientos de los pasajeros junto con otros tres 3C2 * 3C3
Número total de oportunidades = 3C1 * 7C6 * 3C2 * 3C3
4.Beyunka is creating a diagram to prove that a certain triangle is a right triangle.

diagram could be the one that Beyunka is creating?
Option 'D' is the correct option.
The correct diagram for Beyunka creating is given in option D.
What is Right triangle?
When an angle of a triangle is measure 90 degree then the triangle is called a right triangle.
Given that;
Beyunka is creating a diagram to prove that certain triangle is a right triangle.
Since, The right triangle is satisfy the Pythagoras theorem.
Now, By option D;
Let sides of a triangle are,
Hypotenuse (H) = c
Perpendicular side (P) = a
Then, The base of the right triangle = √H² - P² = √c² - a²
And, All other diagrams are not satisfy the Pythagoras theorem.
Thus, The correct diagram for Beyunka creating is given in option D.

Which equation represents the graphed function? O y = -3x + 3 O y = 3x - 3 O y = 3x - 2 / 2 O y=-*x+3
Answer:
y=1/3x+3
Step-by-step explanation:
the general equation for a straight line is y=mx+c.where c is the y cut therefore the y cut on our graph is at (0,3)therefore c is 3
we then find the gradient which is "m" on our equation using the formula m=y2-y1/x2-x1
then we substitute the m and c then tha is the equation.

Solve for a. 2.4a + 8 = 27.2
Answer:
Hello! answer: a = 8
Step-by-step explanation:
2.4 × 8 = 19.2
19.2 + 8 = 27.2 therefore a = 8 hope that helps!
Answer:
a = 8
Step-by-step explanation:
2.4a + 8 = 27.2
2.4a + 8 - 8 = 27.2 - 8

If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of sides? A.20cm B.16cm C.22cm D.23cm
Complete question:
If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of the third sides? A.20cm B.16cm C.22cm D.23cm
Answer:
B. 16 cm
Step-by-step explanation:
Given;
two lengths of the triangle as 15 cm and 4 cm
The length of the third side of the triangle must be less than the sum of the two given sides.
Length of third side < 15 cm + 4 cm
Length of third side < 19 cm
The only option less than 19 cm is B. 16 cm
Therefore, the correct option is B. 16 cm

Solve using the quadratic formula. Approximate answers to the nearest tenth.
Help
Answer:
x = 2.4 or x = 0.3
Step-by-step explanation:
3x² - 8x + 2 = 0
Quadratic formula
x = {-b ±√b² - 4ac} / 2a
a = 3
b = -8
c = 2
x = {-b ±√b² - 4ac} / 2a
= {-(-8) ±√(-8)² - 4*3*2} / 2*3
= (8 ± √64 - 24) / 6
= (8 ± √40) / 6
= (8 ± 2√10) / 6
= 8/6 ± 2√10/6
= 4/3 ± √10 / 6
x = 4/3 + √10 / 6 or 4/3 - √10 / 6
x = 2.4 or x = 0.3

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).
when
[tex] {x}^{3} + a {x}^{2} + 5x + 3[/tex]

the remainder is b. Determine the value of b
x³ + ax² + 5x + 3. x + 2 = 0
x = -2
(-2)³ + a(-2)² + 5(-2) + 3 = 0
-8 + 4a - 10 + 3 = 0
4a - 15 = 0
4a = 15
a = 15/4
Given that a = two and b = 3, what is the value of (ab)?
Answer:

Step-by-step explanation:
a = 2 and b = 3

Answer:
81.25
Step-by-step explanation:
Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.
Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.
Finally, add those two distances together so that you know the total distance:
49.75+31.5 = 81.25
