¿Un camión de carga lleva 32 costales de maíz de 20.5 Kg. Cada uno y 19 con un peso de 48.75 Kg. Cada uno. ¿Cuántos kilogramos de maíz lleva el camión?
Answer:
1,582.25 kilogramos
Step-by-step explanation:
Para determinar los kilogramos de maíz que lleva el camión, se debe multiplicar el peso de los dos tipos de bultos que lleva por la cantidad de cada uno y sumar estos valores para obtener la respuesta:
(20.5*32)+(48.75*19)=656+926.25=1,582.25
De acuerdo a esto, el camión lleva 1,582.25 kilogramos de maíz.

Water boils at different temperatures at different elevations. The boiling temperature of water is 212 degrees * F sea level (0 feet ) but drops about 1.72 degrees * F for every 1,000 feet of elevation. Write a formula for the boiling point at a given elevation. Then solve the formula for the elevation when the boiling point for water is 190 degrees F.
Answer:
The elevation when the boiling point of water is [tex]190[/tex] °[tex]F[/tex] is 12790.70 feet
Step-by-step explanation:
Let every 1,000 feet of elevation be [tex]x[/tex]. Hence, we can write
[tex]T = 212[/tex] [tex]- 1.72x[/tex]
Where [tex]T[/tex] is the boiling temperature of water at different elevations
Now, to the determine the elevation when the boiling point of water is [tex]190[/tex] °[tex]F[/tex].
We will determine [tex]x[/tex] by putting [tex]T = 190[/tex] °[tex]F[/tex].
Hence,
[tex]T = 212[/tex] [tex]- 1.72x[/tex]
[tex]190[/tex] [tex]= 212[/tex] [tex]- 1.72x[/tex]
[tex]190 - 212[/tex] [tex]= - 1.72x[/tex]
[tex]- 22[/tex] [tex]= - 1.72x[/tex]
[tex]22 = 1.72x\\x = \frac{22}{1.72} \\x = 12.79070[/tex]
Since [tex]x[/tex] represents every 1,000 feet of elevation, then the elevation when the boiling point of water is [tex]190[/tex] °[tex]F[/tex]
[tex]12.79070[/tex] × [tex]1000\\[/tex] [tex]= 12790.70[/tex] feet
Hence, the elevation when the boiling point of water is [tex]190[/tex] °[tex]F[/tex] is 12790.70 feet
*DIFFICULT QUESTION PLEASE PLEASE ANSWER* An ice cream machine offers three flavors: vanilla, chocolate, and strawberry. Each flavor can be served as a milkshake, in a cone, or in a cup. What is the probability of a customer choosing either a strawberry milkshake or cone? a.) 60% b.) 40% c.) 12% d.) 20%
Answer:
c.) 20%
Step-by-step explanation:
•1/3 chnace of picking Strawberry flavor
•2/3 chance of picking a milkshake or cone serving
(1/3)*(2/3)=2/9=0.222...(approx.)=0.20=20%
Edit for more clarification:
If you have a situation where multiple outcomes are favorable ("or" statements) then you add the odds together. The customer here wouldn't have minded a milkshake or a cone, so we add their odds together to get 2/3.
If you have a situation where a specific combination of outcomes is favorable ("and" statements) then we multiply the odds. The customer would be getting a flavor and a type of serving, so we multiply the odds of each combination together.
(Note that this is technically a simplified version of the general formulas/equations for probabilities so if you go look them up on the internet they might include some other ideas.)

What is the image of the point (8, -3) after a rotation of 90° counterclockwise about
the origin?
Answer:
[tex]\huge\boxed{(3, 8)}[/tex]
Step-by-step explanation:
When we rotate a point 90° counterclockwise around the origin, it's the same as rotating it 270° clockwise around the origin.
When we rotate something 270° clockwise around the origin, the original coordinates (x, y) becomes (-y, x).
y is -3, and -(-3) is just 3, since two negatives make a positive.
x just remains x, but it's in a different position.
This makes the new coordinate [tex](3, 8)[/tex].

It is a customer appreciation week at the vans shoe outlet, Which means all customers are given a 20% discount on all items. A customer comes in with an birthday coupon for an additional 10% off any shoe item, once the first discount has been applied. The customer buys 3 pairs of shoes for $120.00 each. After the two discounts how much does the customer pay?
Answer:
$278.40
Step-by-step explanation:
Note: "...an additional 10% off any shoe item, once the first discount has been applied." (emphasis added).
Note that the customer is buying 3 pairs of shoes for $120 each: 120 x 3 = $360
The first discount is the 20% discount (on every single item), the second discount is the 10% discount coupon of of any item (which signifies one item only).
Solve for the first discount:
$360 x 0.20 = $72
$360 - 72 = $288.
Next, divide $288 by 3 (to get the individual prices of the shoes:
$288/3 = $96.
The customer then uses a birthday coupon for one of the shoes, which gives an additional 10% off.
$96 x 0.10 = 9.6
$96 - 9.6 = $86.4
Remember, the other two shoes still cost $96 each. Add the price together:
$96 + $96 + $86.4 = $278.40
$278.40 will be the total.

In a theater, there are 20 chairs in the first row, each row has 4 more chairs than the previous row, and there are 15 rows. How many chairs are there in the theater?
Answer:
There are a total of 720 chairs in the theater
Step-by-step explanation:
First row = 20 chairs
Second row = 24 chairs
Third row = 28 chairs
The given is an arithmetic progression (A.P)
First term
a = 20
Common difference
d = 4
Number of terms
n=15
Sum of the chairs in the theater with a total of 15 rows
Sum of an A.P = n/2 { 2a + (n-1) d}
= 15/2{ 2*20 + (15-1) 4}
= 7.5 { 40 + (14) 4 }
= 7.5 { 40 + 56}
= 7.5(96)
=720 chairs

solve the simultaneous equation 3x-2y=7 7x+2y=13
Answer: x= 2, y= -1/2
Step-by-step explanation:
The value of x is 2 and y is -1/2
equations are 3x-2y=7 --1
7x+2y=13 --2
lets consider 3x-2y=7 as equation 1,
consider 7x+2y=13 as equation 2
by putting both the equations :-
3x-2y=7
7x+2y=13
we get 10x=20
x=20/10
x=2
Now by putting the value of x in equation 1;
3(2)-2y=7
6-2y=7
-2y=1
y=-1/2
What is a simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y. They are called simultaneous equations because the equations are solved at the same time. Each of these equations on its own could have infinite possible solutions.
What is meant by algebraic equation?algebraic equation, a statement of the equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root.

Subtract 1 from each side
1-1+3|x-5|=10-1
3|x-5|=9
Divide by 3
3/3|x-5|=9/3
|x-5|=3
There is a positive and negative solutions
x-5 =3 x-5 = -3
Add 5 to each side
x-5+5 = 3+5 x-5+5 = -3+5
x = 8 x = 2
Answer:
[tex]x=2,8[/tex]
Step-by-step explanation:
So we have the equation:
[tex]1+3|x-5|=10[/tex]
First, subtract 1 from both sides:
[tex]3|x-5|=9[/tex]
Now, divide 3 from both sides:
[tex]|x-5|=3[/tex]
Definition of absolute value:
[tex]x-5=3\text{ or }x-5=-3[/tex]
For the left, add 5 to both sides.
For the right, add 5 to both sides:
[tex]x=3+5\text{ or } x=-3+5\\x=8\text{ or }x=2[/tex]
Thus, the answers are:
[tex]x=2,8[/tex]
2 feet to 40 inches (ratios)
[tex]\boxed{3:5}[/tex]
We need to first change the measurement of 2 feet to inches, and then find the most simplified version of the resulting ratio.
2 feet = 24 inches (1 foot = 12 inches)
Ratio: 24:40
Simplify ratio:
24/8 = 3
40/8 = 5
Ratio: 3:5
Therefore, the simplified ratio is 3:5 inches.

Answer:
x = 4 + √3 and x = 4 − √3
Step-by-step explanation:
(a−b)^2=a^2−2ab+b2
a^2−b^2=(a−b)(a+b)
−2x^2+16x−26
=−2(1x^2−8x+13)
=−2(x^2−8x+13+3−3)
=−2(x^2−8x+16−3)
=−2(x^2−2(4)x+4^2−3)
=−2((x−4)^2−3)
=−2((x−4)^2−(√3)^2)
=−2((x−4)−√3)((x−4)+√3)
=−2((x−(4+√3)((x−(4−√3))
The zeros of the given algebraic expression are:
−2x^2+16x−26=0
−2((x−(4+√3)((x−(4−√3))=0
x = 4 + √3 and x = 4 − √3
