Answer:
The final price of the textbook rounded to the nearest dollar is $167
Step-by-step explanation:
To solve this problem, we need to find out what 13.5% of $147 equals.
13.5% = 0.135
0.135 x $147 = $19.845
$147 + 19.845 = 166.845
Round to the nearest dollar to get $167

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 2 large boxes and 12 small boxes has a total weight of 223 kilograms. A delivery of 5 large boxes and 3 small boxes has a total weight of 139 kilograms. How much does each type of box weigh?
Answer:
A large box weighs 18.5 kilograms and a small box weighs 15.5 kilograms
Step-by-step explanation:
Create a system of equations where l is the weight of one large box and s is the weight of one small box.
2l + 12s = 223
5l + 3s = 139
Solve by elimination by multiplying the bottom equation by -4:
2l + 12s = 223
-20l - 12s = -556
Add these together and solve for l:
-18l = -333
l = 18.5
So, a large box weighs 18.5 kilograms. Plug in 18.5 as l into one of the equations, and solve for s:
5l + 3s = 139
5(18.5) + 3s = 139
92.5 + 3s = 139
3s = 46.5
s = 15.5
A large box weighs 18.5 kilograms and a small box weighs 15.5 kilograms.
9514 1404 393
Answer:
large: 18.5 kgsmall: 15.5 kgStep-by-step explanation:
Two equations for the total weight can be written in general form as ...
2L +12S -223 = 0
5L +3S -139 = 0
These can be solved using the "cross multiplication method" by computing three differences:
d1 = (2)(3) -(5)(12) = 6 -60 = -54
d2 = (12)(-139) -(3)(-223) = -1668 +669 = -999
d3 = (-223)(5) -(-139)(2) = -1115 +278 = -837
Then the weighs of the boxes are ...
1/d1 = L/d2 = S/d3
L = d2/d1 = -999/-54 = 18.5
S = d3/d1 = -837/-54 = 15.5
The large box weighs 18.5 kg; the small box weighs 15.5 kg.
_____
Additional comment
If the coefficients are written in two rows of four numbers, with the first repeated at the end, the pattern of differences can be seen to be (ad -cb) for [a, b] in the first row and [c, d] in the second row of a pair of adjacent columns. This method of solution is fully equivalent to solution using Cramer's Rule for a system of equations represented by a matrix equation.
Add the first 12 terms of this sequence:

Answer:
Step-by-step explanation:
a₁ = 15
a₂/a₁ = 45/15 = 3
a₃/a₂ = 135/45 = 3
...
It is a geometric sequence with a common ratio r=3.
Sum of first 12 terms = a₁·(1-r¹²)/(1-r)

Desde cierto paradero se transportan 300 pasajeros en
4 microbuses. ¿Cuántos micros se deben aumentar para
que por cada 3 micros se transporten 90 pasajeros?
Se necesitan 10 micros si queremos que cada 3 micros transporten 90 pasajeros.
En principio, sabemos que 300 pasajeros pueden transportarse en 4 microbuses.
Entonces, el numero de pasajeros que va por cada micro será el cociente entre el numero de pasajeros y el numero de micros:
N = 300/4 = 75
Queremos responder:
¿Cuántos micros se deben aumentar para que por cada 3 micros se transporten 90 pasajeros?
Definamos X como el numero de grupos de 3 micros que tendriamos en esta situación.
Entonces 300 sobre X, debe ser igual a 90 (el numero de pasajeros que va en cada grupo de 3 micros)
300/X = 90
300 = 90*X
300/90 = X = 3.33...
Notar que el número total de micros sera 3 veces X:
3*X = 3*3.33.... = 10
Se necesitan 10 micros.

One number is eight less than a second number. Five times the first is 6 more than 6 times the second. Find the numbers.
The value of the first number is -
Answer:
-42/11
Step-by-step explanation:
x = y - 8
5x = 6 - 6y
So now solve the system of equations, divide everything in the second equation by 5 to get it to x = 6/5 - 6y/5
Now...
x = y - 8
x = 6/5 - 6y/5
Now substitute first equation into the second and x is gonna be -42/11 or the first number

Step-by-step explanation:
[tex](2 - 1 \frac{3 {3}^{2} }{?} [/tex]
Answer:
[tex]y=2[/tex]
Step-by-step explanation:
To solve this question, we can use the point-slope formula as we are given points on the line. This is the format:
[tex]y-y_{1} =m(x-x_{1} )[/tex]
The first step is to find the slope by substituting in two of the points. Let's try using (7,2) and (3,2):
[tex]2-2=m(7-3)\\0=4m\\m=0[/tex]
So now we have found that our slope is 0 meaning it is a flat line (shown by the unchanging y values through all three points).
The form for line equations is:
[tex]y=mx+c[/tex]
However, since our m=0, it is simplified to this:
[tex]y=c[/tex]
The y-value for all the points is 2, meaning c=2 (as it is also the y-intercept)
Therefore our final equation is:
[tex]y=2[/tex]

26. A dealer was paid 5% commission on all the recharge cards he sold. If he sold N50,000.00 worth of cards, how much commission did he get?
Answer:
Its N2500
Step-by-step explanation:
5% of 50000 is 2500, so thats how much commision he got
The dealer earned a commission of N2,500.00 on the sale of recharge cards worth N50,000.00.
To calculate the commission earned by the dealer, we need to determine 5% of the total value of the recharge cards sold.
Given that the dealer sold N50,000.00 worth of cards, we'll calculate the commission using the following formula:
Commission = (Percentage/100) * Total Value
In this case, the percentage is 5% and the total value is N50,000.00.
Using the formula, we have:
Commission = (5/100) * N50,000.00
Simplifying the equation:
Commission = 0.05 * N50,000.00
Commission = N2,500.00

Determine if the triangles below are similar. If they are, give the rule that you used to determine similarity.
The triangles are similar due to SAS congruence postulate rule.
What are Similar Triangles?Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides. The triangles that like one another but may not be exactly the same size are said to be similar triangles. When two objects have the same shape but different sizes, they can be said to be similar. This indicates that identical shapes superimpose one another when enlarged. The term "Similarity" refers to this characteristic of like shapes.
Given triangles are similar due to SAS congruence postulate rule.
SAS or Side-Angle-Side Similarity Criterion,
According to the SAS similarity theorem, If any two of the first triangle's sides are exactly proportional to those of the second triangle, and if the angle created by these two sides of each individual triangle is equal, then the two triangles must be similar triangles.

If
A. x = 62; mZROS = 31°
B. x = 60; mZROS = 28°
C. x= 31; mZROS = 62°
D. X = 28; mZROS = 60°
Answer:
x = 31
ROS = 62
Step-by-step explanation:
QOR + ROS = 90 degrees as indicated by the box
28+ 2x = 90
Subtract 28 from each side
2x = 90 -28
2x = 62
Divide by 2
2x/2 = 62/2
x = 31
ROS = 2x = 2*31 = 62
Answer:
C. x= 31; mZROS = 62°
Step-by-step explanation:
90=28+2x
2x= 90-28
2x= 62
x= 62/2
x=31°
2(x)= 2× 31 = 62

A central angle of a circle is an angle formed by any two radii of the circle. These radii each intersect the circle on a point, and the portion of that circle between the two points is called an arc.
As can be seen from the given figure, Q is the center of the circle and RQ and QT are radii of the circle. Clearly, the central angle ∠RQT is formed by the radii RQ and QT.
The points where these radii intersect the circle are R and T respectively. Then, the portion of the circle between R and T is the required arc.
However, this portion can be taken in two ways; the bigger portion between them (found by moving anti-clockwise from R towards T) and the smaller portion between them (found by moving clockwise from R towards T). These are called the major arc and the minor arc between R and T respectively.
Since it is not explicitly mentioned which arc is required, we will tacitly assume that the minor arc is required.
The minor arc between R and T is named by their end points, that is, as RT.
While not required, it should be noted that the major arc between R and T should be named by their end points and a point between them on the arc (for example RVT or RUT)
Thus, the arc formed by the central angle ∠RQT is RT.
