Alberto pagó el año pasado 350 euros por un servicio de teléfono móvil. Si este año ha pagado 378 euros, ¿qué tanto por ciento ha aumentado en el gasto de teléfono móvil?
Answer:
the percentage increase is 5.3%
Step-by-step explanation:
The computation of the percentage increase is shown below:
= (Current year - last year) ÷ (last year)
= (378 euros - 359 euros) ÷ (359 euros)
= 19 euros ÷ 359 euros
= 5.3%
hence, the percentage increase is 5.3%
A candy factory makes 292,827 candies each day. About how many candies will it make in two weeks?
Answer:
4099578
Step-by-step explanation:
There are 7 days in a week. So in two weeks there will be 14 days. If the factory can make 292827 candies a day, we get 14 * 292827 = 4099578 in two weeks.
Step-by-step explanation:
2 weeks = 14 days
No. of candies in two weeks = 14× 292,827= 4,099,578
Write and solve an equation to find the value of x and a missing angle in the triangle below.
Answer:
angle UTS +TSU =TUV
THEREFORE, 81 + 12X =24X+9
THEREFORE, 81 - 9 = 24X - 12X
THEREFORE, 72 = 12X
THEREFORE, 72/12 =X
THEREFORE, x = 6
THEREFORE, ANGLE TSU = 12 * X
= 12 *6
= 72
YOUR ANSWER IS
X=6
TSU=72

2(4a+1)=3a
a=? Help plz
Answer:
a=-0.4
Step-by-step explanation:
2(4a+1)=3a
8a+2 = 3a
5a+2=0
5a=-2
a=-0.4
Answer:
a = -2/5
Step-by-step explanation:
2 (4 [-2/5] + 1) = 3 (-2/5)
2 (-8/5 + 1) = -6/5
2 (-3/5) = -6/5
-6/5 = -6/5

a teacher invested $600 in an account that paid 2% annual simple interest the teacher did not maker any additional deposits or withdrawals. What is the total amount of interest paid by this investment at the end of 3 years?
Answer:
$36.00
Step-by-step explanation:
The formula for simple interest is I = P x r x t where P is the principal amount, $600.00, r is the interest rate, 2% per year, or in decimal form, 2/100=0.02, and t is the time involved, 3....year(s) time periods. So t is 3....year time periods. To find the simple interest, we multiply 600 × 0.02 × 3 to get that the interest is $36.00 . Usually now, the interest is added onto the principal to figure some new amount after 3 year(s), or 600.00 + 36.00 = 636.00.
If f(x)=x^3-12x^2+35x-24f(x)=x 3 −12x 2 +35x−24 and f(8)=0f(8)=0, then find all of the zeros of f(x)f(x) algebraically.
Answer:
The zeros of f(x) are: (x - 1), (x - 3) and (x - 8)
Step-by-step explanation:
Given
[tex]f(x)=x^3-12x^2+35x-24[/tex]
[tex]f(8) = 0[/tex]
Required
Find all zeros of the f(x)
If [tex]f(8) = 0[/tex] then:
[tex]x = 8[/tex]
And [tex]x - 8[/tex] is a factor
Divide f(x) by x - 8
[tex]\frac{f(x)}{x - 8} = \frac{x^3-12x^2+35x-24}{x - 8}[/tex]
Expand the numerator
[tex]\frac{f(x)}{x - 8} = \frac{x^3 - 4x^2 -8x^2 + 3x + 32x - 24}{x - 8}[/tex]
Rewrite as:
[tex]\frac{f(x)}{x - 8} = \frac{x^3 - 4x^2 + 3x - 8x^2 +32x - 24}{x - 8}[/tex]
Factorize
[tex]\frac{f(x)}{x - 8} = \frac{(x^2 - 4x + 3)(x - 8)}{x - 8}[/tex]
Expand
[tex]\frac{f(x)}{x - 8} = \frac{(x^2 -x - 3x + 3)(x - 8)}{x - 8}[/tex]
Factorize
[tex]\frac{f(x)}{x - 8} = \frac{(x - 1)(x - 3)(x - 8)}{x - 8}[/tex]
[tex]\frac{f(x)}{x - 8} = (x - 1)(x - 3)[/tex]
Multiply both sides by x - 8
[tex]f(x) = (x - 1)(x - 3)(x - 8)[/tex]
Hence, the zeros of f(x) are: (x - 1), (x - 3) and (x - 8)

jules has rectangular garden that measures 10feet by 12feet . he wants to plant apples in his garden . his uncle said that one seed packet will be enough to fill in a space 40 square feet will jules garden have enough space to plant 3 seed
Answer:
Yes
Step-by-step explanation:
If the garden is 1O by 12 feet then the entire area is 120 feet. If one seed packet needs 40 feet then there will have to be 120 feet to have enough space for all three.
120 = 120, so Jules has enough space.

What is the proportion of times did you roll a 1? (Already answered)
15 Times (This will be your value of p-hat)
1. Say you want to analyze how likely it is that you rolled the proportion of 1s that you did. Would it be appropriate to use a normal model to figure this out? why or why not?
2. Find the probability that the proportion of 1s that you rolled is less than your value of p-hat. Interpret what you find in context.
Answer:
1. I would think it would be a appropriate to use a normal model to figure this out because sometimes when you are using stuff online you can get the same number like 20 times in a row, whereas, if you use a real dice, you most likely won't roll the same number 20 times.

When randy works 5 hours as a baseball umpire. he earns $77.50. when he works 18 hours, he earns $279.00. which equation represents randy’s earnings(m) for any number of hours(h)?
Answer:
m=15.5h
Step-by-step explanation:
279 divided by 18 and 77.5 divided by 5 equal 15.5 so that is how much randy gets paid per hour (h)
Answer:
h(15.50)=m
Step-by-step explanation:
He earns 15.50 dollar per hour
77.50/5=15.5
279/18=15.5
one angle of a triangle measures 35°. A second angle measures (3x)°, and the third angle measures 2x - 20)°. what is the value of x?
Answer:
x = 33
Step-by-step explanation:
Sum of the angles in a triangle is 180 so,
35 + 3x + 2x - 20 = 180
35 + 5x - 20 = 180
15 + 5x = 180
5x = 180 - 15
x = 165/5
x = 33

Distribute, multiply each term in the parenthesis with the term outside of the parenthesis. Don't forget the laws of exponents, when one multiplies two exponents, with the same base, then one adds the two exponents. A number with no exponential term is two the first degree meaning that it is to the power of one.

The costs of general admission and student tickets to a high school football game are $7 and $4 respectively. The ticket sales for one game totaled $11,200. Write an equation which models the situation.
Answer:
7x + 4y = 11,200
Step-by-step explanation:
Let
Number of Admission tickets A = x
Number of Admission tickets B = y
Cost of Admission tickets A = $7
Cost of Admission tickets B = $4
Total cost = $11,200
The equation is:
7x + 4y = 11,200

Given:
The functions are
[tex]f(x)=x^2[/tex]
[tex]g(x)=x+6[/tex]
To find:
The value of g(f(0)).
Solution:
We have,
[tex]f(x)=x^2[/tex]
Putting x=0, we get
[tex]f(0)=0^2[/tex]
[tex]f(0)=0[/tex]
Now,
[tex]g(f(0))=g(0)[/tex] [tex][\because f(0)=0][/tex]
[tex]g(f(0))=0+6[/tex] [tex][\because g(x)=x+6][/tex]
[tex]g(f(0))=6[/tex]
Therefore, the value of g(f(0)) is 6 and the correct option is B.

PLEASE I NEED SOMEONE TO HELP MY ASSIGNMENT, DUE IS TOMMOROW. (´;︵;`)
Answer:
Step-by-step explanation:
A) In ΔONE & ΔEST
ON // ST (Construction) and NS is transversal.
∠1 = ∠4 {alternate interior angles}
NE =ES {Given E is midpoint}
∠2 = ∠3 {Vertically opposite angle}
ΔONE ≅ ΔEST { A S A congruent}
OE ≅ TE {CPCT}
ON = ST {CPCT} ---------(I)
ON = OH -----------------(II)
From (I) & (II)
OH = ST & OH // ST (construction)
OHST is a parallelogram.
So, OE // HS -----------------(A)
OE = TE
OT = 2OE
OE = (1/2)OT
OE = (1/2)HS ------------------(B)
From A & B , midpoint theorem is proved

The value of x in the expression
2x/3 - 7 = 5 is
Answer:
The answer is X = 18
Step-by-step explanation:
2x/3 - 7 = 5
Multiply both sides if the equation by 3 : 2x - 21 = 15
Move the constant to the right hand side and change its sign : 2x = 15 + 21
Calculate 2x = 15 + 21
2x = 36
Divide both sides of the eqaution by 2 : 2x = 36
x = 18
Answer X = 18
If the perimeter of a rectangle garden with a width of 15 is 125, what is the perimeter of the daily record it if the scale factor is 60%
Answer:
(here i assume that the daily record is another rectangle)
For a rectangle with width W and length L, the perimeter is:
P = 2*W + 2*L
in this case we know that:
P = 125
W = 15
Replacing these in the perimeter equation we get:
125 = 2*15 + 2*L
125 = 30 + 2*L
125 - 30 = 2*L
95 = 2*L
95/2 = L = 47.5
Now we know that the daily record has a scale factor of 60%.
This means that each measure of this rectangle is (60%/100%) times the equivalent measure of the rectangle garden.
Then if the width of the daily record is W' and the length of the daily record is L'
This means that:
L' = (60%/100%)*L = 0.6*L = 0.6*47.5
W' = (60%/100%)*W = 0.6*W = 0.6*15
Then the perimeter is:
P' = 2*0.6*47.5 + 2*0.6*15 = 75
(notice that is exactly the same than multiplying the original perimeter by (60%/100%) = 0.6)
Parallel lines cut by a transversal...I need X, no decimals.
(Hint: The answer is either 9 or 26)
Answer:
x = 26
Step-by-step explanation:
These angles are equal b/c of alt exterior angles
9x + 18 = 10x - 8
9x - 10x = -8 - 18
-x = -26
x = 26
