Answer:
Espero y esto te ayude :) si me falto algo lo siento.
Step-by-step explanation:
Si se oferta un producto al 10% de descuento, esto significa que el precio final del producto será 90% del precio original. Para hallar estos datos, debemos usar una regla de tres, de la siguiente forma:
100% 90%
-------------------- → ---------------------------
Precio Original Precio con Descuento?
SARAPES
- Ana: descuento (14), precio rebajado 126
Precio rebajado = 140.90 / 100 = 126
Descuento: 140 - 126 = 14
- Javier: descuento (8), precio rebajado 72
Precio rebajado = 80.90 / 100 = 72
Descuento: 80 - 72 = 8
ARETES
- Luis: descuento (5), precio rebajado 72
Precio rebajado = 50.90 / 100 = 45
Descuento: 50 - 45 = 5
- Ana: Precio original (60) , descuento (6), precio rebajado 54
Precio original: X.0,10 = 6
X = 60
Precio rebajado: 60 - 6 = 54
- Javier: Precio original (40) , descuento (4), precio rebajado 36
Precio original: X.0,10 = 4
X = 40
Precio rebajado: 40 - 4 = 36
Samantha has $300 for guitar lessons to learn her favorite song. Mrs. Jones charges $80 per lesson and requires three lessons to teach Samantha the song. Mr. Beliz charges $62 per lesson and requires four lessons to teach Samantha the song. Use integers to represent what each teacher charges. Which is the better deal for Samantha?
Answer:
Mrs. Jones has the better deal
Step-by-step explanation:
Samantha has $300
Mrs. Jones charges $80 per lesson and she requires three so we do 80* 3 (the lessons) which equals 240
Mrs. Beliz charges $62 per lesson and requires 4 lessons so we do 62*4 (the lessons) which equals 248
240<240 (so Mrs. Jones has the better deal, she wants less money)
Answer:
Mrs. Jones

find angle prq
please solve this
Answer:
∠ PRQ = 55°
Step-by-step explanation:
The angle subtended at the centre by an arc is twice the angle subtended at the circumference by the same arc, thus
∠ PQR = 0.5 × 110° = 55°

Answer:
There is 2145.52 cubic inches of air in the ball
Step-by-step explanation:
A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.
Given
Radius = r = 8 in
The volume of sphere is given by:
[tex]V = \frac{4}{3} \pi r^3[/tex]
Putting the values we get
[tex]V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3[/tex]
Hence,
There is 2145.52 cubic inches of air in the ball

X=9.5
So x is less than 10
Answer:
Step-by-step explanation:
Because of the plus 5. You know for a fact that 10 times 10 is 100 but you need something less than 10 for the equation to be true since you're adding onto the answer to get 100
Write the slope-intercept form of an equation for the line that passes through (2, 3) and is parallel to the graph of y = 2x -1
Answer:
ok
Step-by-step explanation:
Answer:
y = 2x -1
Step-by-step explanation:
when a two lines are parallel to each other that means they have the same slope.
you use point slope formula to find a line with the same slope and passes through (2,3)
y - y' = m(x - x') is the general form so you plug in (2,3) and the slope and you get
y - 3 = 2(x -2)
first your distribute the 2 into the parenthesis and you get
y-3 = 2x -4
now add 3 to both sides
y = 2x -1

How many 2 3 -quart portions are in 7 1 2 quarts of soup?
Answer:
[tex]Number = 11\frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]Soup = 7\frac{1}{2}[/tex] quarts
[tex]Portion = \frac{2}{3}[/tex] quarts
Required
Determine the number of portions in the soup
The question illustrates division of fractions and to solve this question, we simply divide the size of the soup by the size of the given portion
[tex]Number = Soup/Portion[/tex]
Substitute values for Soup and Portion
[tex]Number = 7\frac{1}{2}\ quarts /\frac{2}{3} \ quarts[/tex]
[tex]Number = 7\frac{1}{2}/\frac{2}{3}[/tex]
Convert mixed fraction to improper fraction
[tex]Number = \frac{15}{2}/\frac{2}{3}[/tex]
[tex]Number = \frac{15}{2} * \frac{3}{2}[/tex]
[tex]Number = \frac{15*3}{2*2}[/tex]
[tex]Number = \frac{45}{4}[/tex]
[tex]Number = 11\frac{1}{4}[/tex]
Hence, there are [tex]11\frac{1}{4}[/tex] of [tex]\frac{2}{3}[/tex] quarts in [tex]7\frac{1}{2}[/tex] quarts of soup

Answer:
(3/5, 1/5)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationSolving systems of equations using graphingStep-by-step explanation:
Step 1: Define systems
3x + y = 2
4x + 3y = 3
Step 2: Rewrite systems
y = 2 - 3x
4x + 3y = 3
Step 3: Solve for x
Substitute in y: 4x + 3(2 - 3x) = 3Distribute 3: 4x + 6 - 9x = 3Combine like terms: -5x + 6 = 3Isolate x term: -5x = -3Isolate x: x = 3/5Step 4: Solve for y
Define original equation: 3x + y = 2Substitute in x: 3(3/5) + y = 2Multiply: 9/5 + y = 2Isolate y: y = 1/5Step 5: Check
Graph the systems of equations.
Answer:
x = 3/5, y = 1/5
Step-by-step explanation:
Starting with:
3x + y = 2
4x + 3y = 3
Multiplying the first equation by -3:
-9x - 3y = -6
4x + 3y = 3
Adding the equations:
-5x = -3
Simplifying:
x = 3/5
Substituting x = 3/5 into the first equation:
9/5 + y = 2
Subtracting:
y = 1/5
How do I solve this equation?
Answer:
no solution
Step-by-step explanation:
[tex]|x+1|+6 = 2[/tex][tex]|x+1|=-4[/tex]Therefore, there is actually no solution! No solution of x, when added to 1, can make negative 4. This is because the absolute sign (the symbol that looks like bars: |#|) automatically makes a number positive.Answer:
no solution
