A trapezoid is a geometric figure with 4 sides, of which two are parallel.
The area is the measure of a figure, that is, the measure of its interior region.
Before starting to calculate the area of the trapezoid, we have as data:
Minor base (b) = 15 ftMajor base (B) = 23 ftHeight (H) = 11 ftThe formula to calculate the area of the trapezoid is:
\(\boldsymbol{\sf{A=\dfrac{(B+b)*h}{2} \ \ \longmapsto \ Formula }}\)
We substitute the data in the formula, this means that instead of the letters I am going to add the value.
\(\boldsymbol{\sf{A=\dfrac{(23 \ ft+15 \ ft)*11 \ ft}{2} }}\)
We add the Major Base + The Minor Base, and we are left.
\(\boldsymbol{\sf{A=\dfrac{38 \ ft*11 \ ft}{2} }}\)
We multiply the sum of both bases, by the height.
\(\boldsymbol{\sf{A=\dfrac{418 \ ft^{2} }{2} }}\)
We divide both sides of the equation by 2.
\(\boxed{\boldsymbol{\sf{A=209 \ ft^{2} }}}\)
Answer: The area of the trapezoid is 209 ft². The correct option is the alternative "C".

Which equation is shown by the model?
See picture below
Based on the information we can infer that the equation shown in the image is 1.23 - 0.35 = 0.88 (option B).
How to identify the correct equation?To identify the correct equation we must look at the graph and identify the information it provides. In this case we have two squares divided into 100 squares each. Additionally, the square on the left has 88 squares painted in red and 12 squares with an X inside. In the case of the square on the right, it has 23 squares colored in red with an X inside.
In total we have 123 squares painted in red, which in decimal number is equivalent to 1.23. On the other hand, the number of squares painted red and with an X inside is 35, this value would be 0.35.
On the other hand, the squares painted only in red are 88, so the equivalent in decimal numbers would be 0.88. Therefore, the correct way to express this relationship through an equation would be:
1.23 - 0.35 = 0.88 (option B).Learn more about equations in: https://brainly.com/question/29538993

Cierta clase de microbio se duplica en cada minuto. Si se coloca un microbio en un recipiente de una capacidad determinada, este se llena a los 30 min. ¿En que tiempo se llenará el recipiente si se colocan 2 microbios?
Answer:
En este problema se trata de una función exponencial, donde la cantidad de microbios en el recipiente se duplica cada minuto.
Si x representa el número de minutos transcurridos y y la cantidad de microbios en el recipiente, entonces se puede expresar la función exponencial como:
y = a * (2)^x
Donde "a" es la cantidad inicial de microbios en el recipiente, en este caso a = 1.
Después de 30 minutos, la cantidad de microbios en el recipiente es:
2^30 = 1,073,741,824
Esto significa que si se coloca un solo microbio en el recipiente, se tardará 30 minutos en llenarlo.
Si se colocan 2 microbios en el recipiente, entonces la cantidad inicial de la función exponencial es a = 2, y se busca el valor de x tal que:
2 * (2)^x = 1,073,741,824
Dividiendo ambos lados por 2, se tiene:
(2)^x = 536,870,912
Tomando logaritmos base 2 en ambos lados, se tiene:
x = log2(536,870,912) = 29
Por lo tanto, si se colocan 2 microbios en el recipiente, se tardará 29 minutos en llenarlo.

Jon is hanging a picture. He wants to center it horizontally on the wall. The picture is 32 1/2 inches long, and the wall is 120 3/4 inches long. How far from each edge of the wall should he place the picture? Please answer quickly.
Answer:
44.125 inches
Step-by-step explanation:
Given that:
Length of picture = 32 1/2 inches
Length of wall = 120 3/4 inches
Hence, to center picture horizontally ;
Distance from the edge of the wall in which the picture should be placed :
(Length of wall - length of picture) / 2
(120 3/4 - 32 1/2) / 2
(483/4 - 65/2) / 2
Take the L. C. M of 4 and 2 = 4
((483 - 130) / 4) ÷ 2
(353 / 4) ÷ 2
(353 / 4) * (1 / 2)
= 353 / 8
= 44 1/8
= 44 1/8
= 44.125 inches
The space that will be left in each side of the picture from the edge of the wall if Jon is to hang the picture at the center of the wall horizontally is: 44.125 inches.
The wall that Jon wants to hang the picture has been sketched in the diagram attached below (see attachment).
Given the following:
Length of the wall = 120 3/4 inches = 120.75 inchesLength of the picture = 32 1/2 inches = 32.5 inchesThe space in each edge of the wall = xTotal length of space to be left = x + x = 2xTherefore, the following equation can be derived as follows:
\(2x + 32.5 = 120.75\)
Solve for x\(2x = 120.75 - 32.5 \\\\2x = 88.25\\\\x = \frac{88.25}{2} \\\\\mathbf{x = 44.125 $ inches}\)
Therefore, the space that will be left in each side of the picture from the edge of the wall if Jon is to hang the picture at the center of the wall horizontally is: 44.125 inches.

a contracter purchases 7 dozen pair of padded work glovs for $103.32. he incorrectly calculates the unit price at $14.76 what error did th contractor make
Answer:
The contractor made an error in calculating the unit price of the padded work gloves.
Step-by-step explanation:
To find the unit price of an item, we need to divide the total cost of the item by the number of units purchased. In this case, the contractor purchased 7 dozen pair of padded work gloves, which is equal to 7 x 12 = 84 pair of gloves. Therefore, the unit price of the padded work gloves is $103.32 / 84 pair = $1.23 per pair.
The contractor incorrectly calculated the unit price as $14.76, which is an error of $14.76 - $1.23 = $13.53. This error occurred because the contractor did not correctly take into account the number of units purchased when calculating the unit price.

A milk truck carries milk with density 64.6 lb/ft3 in a horizontal cylindrical tank with diameter 8 ft.
(a) Find the force exerted by the milk on one end of the tank when the tank is full. (Round your answer to the nearest integer.) lb
(b) What if the tank is half full?
Answer:
a) 12989 Ib
b) 2756.3 Ib
Step-by-step explanation:
Density of milk = 64.6 Ib/ft^3
Diameter of tank = 8 ft
radius = 4 ft
a) Calculate force exerted by milk on one end of tank when Tank is full
pressure on strip ≈ 64.6 ( 4 - yi ) i.e. surface of milk = 4
Total force = 129.2 * \(\int\limits^4_4 {4-y} \sqrt{16-y^2} \, dx\)
∴Force exerted = 129.2 * Area of semicircle( radius =4 ) * radius
= 129.2* 8π * 4 ≈ 12989 Ib
b) Force exerted when Tank is half full
pressure on strip ≈ 64.6 ( 0 - yi ) i.e. surface of milk = 0
Total force = 129.2 * \(\int\limits^0_4 {0-y} \sqrt{16-y^2} \, dx\)
∴ Force exerted ≈ 2756.3 Ib

On analyzing the data given in question we get to know that the sensitivity is negative.
Our function is 40 + 24 x 2.4 /1 + 4x to the point.
For the time being, our first task is to determine the sensitivity, which is the derivative of our discovery. The quotient rule, whose derivative we shall be utilizing, says that the derivative of F org equals G f prime minus f g prime all over g squared.
The bottom function is one plus four times the top function's derivative, or 40.4 times. 40 has a derivative of zero.
When a light source is x cm away from a light probe, the light's intensity is measured as y microwatts per square cm. The outcomes are displayed as ordered pairs( x , y).
So we just need to multiply 24 x240.4.
Using the power rule, we can reduce the 0.4 point to 9.6 x to the minus 0.6.
We subtract one from the initial exponents minus the top function 40 + 24 x to the point for times the bottom function's derivative 10 So we have the derivative of four additional 40.4 by the power rule,
we bring down the 0.4 multiplied by four against 1.6 next to the minus 0.6, and we divide all of that by one plus four x to the 40.4 squared.

The length of WZ is 7.5 inches and the measurement of angle Y is 45 degrees for the similar shapes QRST and WXYZ.
What are similar shapesSimilar shapes are two or more shapes that have the same shape, but different sizes. In other words, they have the same angles, but their sides are proportional to each other. When two shapes are similar, one can be obtained from the other by uniformly scaling (enlarging or reducing) the shape.
If Lynn's quadrilateral WXYZ is a smaller shape of QRST, and they are similar, then:
the side QR corresponds to WX and QR corresponds to WX, so:
QR/WX = QT/WZ
2/5 = 3/WZ
WZ = (3 × 5)/2 {cross multiplication}
WZ = 15/2
WZ = 7.5

At a restaurant, two salads, two sandwiches, and one drink cost $23. Three salads, one sandwich, and three drinks cost $24.50. A salad costs twice as much as a drink. How much does each item cost?
Answer:
Salad cost = $4
Sandwiches cost= $6.5
Drinks cist= $2
Step-by-step explanation:
Let salad = x
Sandwiches= y
Drinks= z
2x+2y+z= 23...... equation one
3x+y+3z= 24.5 .... equation two
X= 2z.... equation three
Substituting equation three into equation one and two
2(2z) +2y +z= 23....
3(2z)+y +3z= 24.5....
2y +5z= 23.... equation 4
y + 9z= 24.5...equation 5
Multiplying equation 5 with 2
2y +5z= 23
2y + 18z= 49
Solving simultaneously
13z= 26
Z= 26/13
Z= 2
2y +5z= 23
2y +5(2)= 23

How to find the value of x?Here we know that the lines G and M are parallel, meaning that the two shown angles are alternarte exterior angles, and thus, have the same measure, then we can write:
5*(x + 6) = 9*(x - 6)
We can solve that linear equation for x:
5x + 30 = 9x - 54
30 + 54 = 9x - 5x
84 = 4x
84/4 = x
