Answer:
Ben spent $9.32 on stamps total
Step-by-step explanation:
19x0.39= 7.41 because it says he bought 19 of these and they each cost $0.39 so you just multiply the two
8x0.24= 1.92 because of the same reason for the other it says he bought 8 of these and each costs $0.24 so you just multiply the two which gets you 1.92
next you add together the two totals of the stamps which is 7.41 and 1.92
7.41+1.92= 9.32
A school carnival sold 90 early-admission tickets and 810 regular tickets. What percentage of the tickets sold were early-admission tickets?
Answer:
11.12 %
Step-by-step explanation:
Given that,
There are 90 early admission tickets.
There are 810 regular tickets.
We need to find the percentage of the tickets sold were early-admission tickets.
[tex]P=\dfrac{90}{810}\times 100\\\\=11.12\%[/tex]
So, the required percentage is 11.12 %.

Alejandro put down a deposit of $75.00 on a graduation ring, and he then began making weekly payments of $12.50 until the ring was fully
paid for.
If the price of the graduation ring was $225.00, how many weekly payments of $12.50 did Alejandro make?
Answer:
12 weekly payments
Step-by-step explanation:
Here, we want to get the number of weeks in which he made payment for the ring
We start by subtracting the deposit,
That would be;
225-75 = 150
Now, we proceed to divide what ie left by the weekly payment to get the number of weeks
That would be;
150/12.5 = 12

12 weekly payments

Step-by-step explanation:
The parameters of the triangle having bisected angle are;
The length of the opposite and adjacent side of one of the halves of the bisected angle = 6 and 14 respectively
The length of the opposite and adjacent side of the other half of the bisected angle = (3·x - 12) and 21 respectively
By the angle bisector theorem, we have;
[tex]\dfrac{14}{6} = \dfrac{21}{3\cdot x - 12}[/tex]
Simplifying, we get;
[tex]\dfrac{14}{6} = \dfrac{2 \times 7}{2 \times 3} = \dfrac{7}{3}[/tex]
[tex]\dfrac{21}{3\cdot x - 12} = \dfrac{3 \times 7}{3 \times (x - 4)} = \dfrac{7}{x - 4}[/tex]
[tex]\dfrac{7}{3} = \dfrac{7}{ x - 4}[/tex]

Answer: The next fraction in the sequence will be 5/20.
Step-by-step explanation:
9/20 is the first fraction.
2/5 is equal to 8/20, so that is the second fraction.
7/20 is the third fraction.
3/10 is equal to 6/10, so that is the fourth fraction.
By now we can see that there is a pattern, because the first fraction's numerator began with 9, the next 8, then 7, and 6. We also simplfied all he fractions so that they had the denominator 20. Because of this, the next fraction in the sequence will be 5/20.

7 (10pts) In △ABC, m∠B = 90°, m∠C = 15°, M ∈ BC . If m∠BAM = 60°, AM = 10 in. Find: AB and MC. B (5pts) Find MC. Answer: MC = in. SAVE ANSWER Need help with formatting? Next
Answer:
MC is 10 in.
Step-by-step explanation:
The given parameters for the triangle ΔABC are;
m∠B = 90°
m∠C = 15°
M ∈ BC
m∠BAM = 60°
AM = 10 in.
From the given information, ΔABC is drawn using Microsoft Visio, from which we have ΔACM
m∠CAM = 75° - 60° = 15° (By angle addition postulate)
m∠CAM = 15° = m∠C, therefore, ΔACM is an isosceles triangle with base angles, m∠CAM and m∠C each equal to 15°
AM = 10 in. = MC, by definition of isosceles triangle
∴ MC = 10 in.

Simplify the following expression 3°?
Answer: 1
Anything to the 0 power is 1
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
As you may already know, the number (the base) to the power (the exponent) is how many times you multiply the base. For instance:
3² = 3 * 3
3³ = 3 * 3 * 3
However, anything to the zeroth power is 1.
Why?
Well, for those above examples, take 3², you can also write it as:
3² = 1 * 3 * 3
It's just 1 times how many of that number. In 3 squared, there are twos 3's, not to be confused with 3 * 2.
In 3 to the zeroth power, there are zero 3's:
3° = 1
Now it has only the one.
This is just the way I was taught to think about it, but I'm sure there's a better explanation than mine.

Answer:
x = 4, BC = 17
Step-by-step explanation:
AC = AB + BC , substitute values
7x - 3 = 2x + 3x + 5
7x - 3 = 5x + 5 ( subtract 5x from both sides )
2x - 3 = 5 ( add 3 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4

Answer:
1. x = 3
2. x = 6
3. not sure
Step-by-step explanation:
5x +2 (x+7) =14x -7
First expand the expandables
5x +2x +14 =14x-7
7x +14 =14x -7
14x -7x =14+7
7x=21 . Divide both sides by 7
x=3.
Step-by-step explanation:
1. 5x +2x + 2*7 =14x-7
7x + 14 = 14x - 7
14 +7 = 14x - 7x
21 = 7x
21/7 =x
4 =x

A) ¿Cuántos arboles tiene cada hilera? B) ¿Cuántas hileras necesita?
Answer:
A) Se requiere 10 árboles por hilera.
B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.
Step-by-step explanation:
A) A continuación, realizamos la descomposición factorial de cada número:
Naranjos
[tex]720 = 2 \times 2 \times 2 \times 2 \times 3\times 3\times 5[/tex]
[tex]720 = 2^{4}\times 3^{2}\times 5[/tex]
Mandarinos
[tex]250 = 2\times 5\times 5\times 5[/tex]
[tex]250 = 2\times 5^{3}[/tex]
Mamoneros
[tex]360 = 2\times 2\times 2\times 3\times 3\times 5[/tex]
[tex]360 = 2^{3}\times 3^{2}\times 5[/tex]
Nísperos
[tex]480 = 2\times 2\times 2\times 2 \times 2\times 3\times 5[/tex]
[tex]480 = 2^{5}\times 3\times 5[/tex]
El máximo común divisor de los cuatro números representa el número de árboles de cada hilera considerando el menor número posible de hileras, cuyo valor es [tex]2\times 5 = 10[/tex]. Se requiere 10 árboles por hilera.
B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por el resultado del punto anterior:
Naranjos
[tex]x = \frac{720}{10}[/tex]
[tex]x= 72[/tex]
Mandarinos
[tex]x = \frac{250}{10}[/tex]
[tex]x = 25[/tex]
Mamoneros
[tex]x = \frac{360}{10}[/tex]
[tex]x = 36[/tex]
Nísperos
[tex]x = \frac{480}{10 }[/tex]
[tex]x = 48[/tex]
El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.
Teniendo en cuenta la definición de m.c.m:
A) Se requieren 10 árboles por hilera.
B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.
A) Para hallar la cantidad de árboles que posee cada hilera debes hallas el m.c.d entre 720, 250, 360 y 480.
El máximo común divisor, m.c.d., de dos o más números es el mayor número que divide a todos de manera exacta, es decir, es el mayor de los divisores que tienen en común dos o más números.
El mínimo común múltiplo se suele expresar con las siglas m.c.d. (a, b), siendo a y b los números.
Para calcular el mínimo común múltiplo de dos o más números, de debe descomponer los números en factores primos (son los números que sólo son divisibles por sí mismos o por el número 1). En este caso:
720= 2×2×2×2×3×3×5= 2⁴×3²×5
250=2×5×5×5= 2×5³
360=2×2×2×3×3×5= 2³×3²×5
480=2×2×2×2×2×3×5= 2⁵×3×5
El mínimo común múltiplo se obtiene escogiendo todos los factores comunes, elevados a la menor potencia. Es decir, se escoge aquellos factores que aparecen en todas las descomposiciones la menor cantidad de veces. En este caso:
mcd (720,250,360, 480)= 2×5= 10
Entonces, se requiere 10 árboles por hilera.
B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por la cantidad de árboles que se requiere por hilera:
Naranjos: 720÷10= 72
Matas de mandarina: 250÷10= 25
Mamon: 360÷10= 36
Níspero: 480÷10= 48
El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

Answer:
If Carter bikes 1/4 mile in 5/6 minutes, he bikes 1/4 mile in 50 seconds. (5/6 of a minute is equal to 50 seconds)
At this rate, if Carter bikes 1/4 mile in 50 seconds, he will be able to bike 2/4 of a mile in 100 seconds, 3/4 of a mile in 150 seconds, and a whole mile (4/4) in 200 seconds.
Converting 200 seconds to minutes, we have that it takes Carter 3 1/3 minutes to bike 1 mile.
