8 m
Answer:
The area of trapezoid is 36 [tex]m^2[/tex].
Step-by-step explanation:
To find the area of a trapezoid, you need this formula:
[tex]A = \frac{(a+b)}{2} \times h[/tex]
[tex]a =[/tex] long base
[tex]b =[/tex]short base
[tex]h =[/tex] altitude (height)
-Use the following measures of trapezoid for the formula:
[tex]A = \frac{(8+4)}{2} \times 6[/tex]
-Then, you solve the formula:
[tex]A = \frac{(8+4)}{2} \times 6[/tex]
[tex]A = \frac{12}{2} \times 6[/tex]
[tex]A = 6 \times 6[/tex]
[tex]A = 36[/tex]
So, therefore, the area of a trapezoid is 36 [tex]m^2[/tex].

Determine between which consecutive integers the real zeros of f(x) = x^3 - 2 are located.
a. between 1&2
c. between 0&1
b. between -1&0
d. between -2&-1
Answer:
Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".
Step-by-step explanation:
In order to find the zeros of a function we need to find at which values for "x" make f(x) equal to zero. Therefore we have:
[tex]f(x) = x^3 - 2 \\0 = x^3 - 2\\x^3 - 2 = 0\\x^3 = 2\\x = \sqrt[3]{2} = 1.2599[/tex]
Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".
The space capsule is on its way back to earth after deploying its first two parachutes falls at a speed of 100 mph what is the space capsules velocity?
Answer:
Step-by-step explanation:
Velocity is the speed of an object in a definite direction. In mechanics, velocity is a vector quantity. It requires magnitude and direction to make any sense. Velocities are expressed per unit time.
The SI unit of time is the second.
Now, suppose we need the velocity in feet per second. A simple calculation will help:
feet per second = miles per hour × 1.466667 [ in other words, one mile per hour equals 1.466667 feet per second]
For a space capsule moving at 80 miles per hour, the velocity is given by
= 100 × 1.466667
= 146.67 ft/s [feet per second]
Alculate the amount of heat transferred when 710 grams of water warms from an initial temperature of 4.0 ºC to a final temperature of 25.0 ºC. The specific heat capacity of liquid water is 4.184 J/g ºC. Please express you answer as a number in units of kJ, and be careful about the sign (is the answer a positive or negative number?) since that shows the direction of heat flow.
Answer:
The Quantity of heat require is [tex]0.062kJ[/tex]
Step-by-step explanation:
This problem bothers on the topic of heat capacity.
Given data
mass of water m= [tex]710 grams[/tex]
converting from grams to kg we have =[tex]\frac{710}{1000} = 0.71kg[/tex]
initial temperature T1= 4°C
final temperature T2= 25°C
heat capacity of water = [tex]4.184 J/g[/tex]
The expression for the quantity of heat required is given has
[tex]Q= mc(T2-T1)[/tex]
substituting our given data we have
[tex]Q= 0.71*4.184*(25-4)\\Q= 2.97*(21)\\Q= 62.38J\\[/tex]
In kilograms we have to divide by [tex]1000[/tex]
[tex]Q= \frac{62.38}{1000} = 0.062kJ[/tex]

Step-by-step explanation:
A cash card has a starting value of $25. If the card is not used within the first year of its purchase, the value on the card begins to decrease by $2.50 per month.
The relationship between the number of months after the first year and the amount remaining on the card is ____________. (continuous, discrete)
The independent variable is the ___________. (amount remaining on the card, numbers of months after the first year)
The dependent variable is the _____________. (amount remaining on the card, numbers of months after the first year)
Answer:
The relationship between the number of months after the first year and the amount remaining on the card is discrete.
The independent variable is the
number of months after the first year.
The dependent variable is the
amount remaining on the card.
The answers are; The relationship between the number of months after the first year and the amount remaining on the card is discrete.
The independent variable is the number of months after the first year.
The dependent variable is the amount remaining on the card.
What is dependent and independent variables?The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Given that, A cash card has a starting value of $25. If the card is not used within the first year of its purchase, the value on the card begins to decrease by $2.50 per month.
The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse, which meant that, when the number of months after the first year increases, the amount on the remaining car decreases, linearly.
The Independent variable is the numbers of months after the first year.
The Dependent variable is the amount on the remaining card, because this amount depends on the time it has passed since the first year, which is our independent variable.
If we call "Y" our dependent variables and "X" our Independent variable, This relationship can be written as Y= 25 - 2.5x.
If no months had passed since the first year, then x= 0 and the amount in the card equals $25, while if one month has passed since the first year, x= 1 and y= 22.5 (The amount in the card in this case is $22.5.)
Hence, The answers are a) discrete b) numbers of months after the first year c) amount remaining on the card

You want to buy DVDs and are searching for the best price. You found two stores having sales on DVDS. Which is the one that offers the best percentage off? Then explain your reasoning.
Store 1 - Buy 2 for the price of one!
Store 2 - Buy 3 for the price of two!
Answer:
Store 1 Has a better deal as your paying 1.50 less which is 50 percent off
Step-by-step explanation:
Lets say a DVD costs 1.50
so if you bought 2 for the price of one it would be 1.50
3 for the price of 2 would be 3 dollars.
If you were to buy 2 CDS for the Price of 2 that would be 3 Dollars
3 CDS for the price of 3 would be 4.50
The Amount of money depends on the cost of 1 CD.
Store 1 has a 50 percent discount while Store 2 has roughly a 35 percent discount.

Answer:
x =5
y = 35
Step-by-step explanation:
y = 7x
y = 3x+20
Since they both equal y, we can set them equal to each other
7x = 3x+20
Subtract 3x from each side
7x-3x = 3x+20-3x
4x= 20
Divide each side by 4
4x/4 =20/4
x = 5
Now find y
y = 7x
y = 7(5)
y = 35

-32=-7x-8y slope intercept form
Answer:
y = [tex]-\frac{7}{8}[/tex]x + 4
Step-by-step explanation:
-32 = -7x - 8y
Slope-intercept: y=mx+b
First, we can add 8y on both sides so we can get u by itself.
8y - 32 = -7x
Now, we can add 32 to both sides.
8y = -7x + 32
Now, we divide 8 on both sides of the equation so we can get y by itself just like in the slope-intercept formula.
y = [tex]\frac{-7}{8}[/tex]x + [tex]\frac{32}{8}[/tex]
Lastly, we can simplify and you will have your answer.
y = [tex]-\frac{7}{8}[/tex]x + 4

- Ms. McNeil buys 2.4 gallons of gasoline. The total cost is $7.56. The
equation 2.4p = 7.56 can be used to find the price p in dollars of
one gallon of gasoline. What is the price of one gallon of gasoline?
Answer:
The price of one gallon of gasoline is $3.15
Step-by-step explanation:
If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":
2.4 p = 7.56
then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:
p = 7.56/2.4
p = $3.15
so this is the price per gallon of gasoline.

EF is a median of trapezoid ABCD. The length of AB is 12, and the length of CD is 18. The length of BF is 4. What is the length of FC?
Answer:
Step-by-step explanation:
The diagram representing the trapezoid is shown in the attached photo. The median EF is a line segment that is half way between the 2 bases. The length of the median is the average of the two bases. Therefore,
EF = (12 + 18)/2 = 15
Two similar trapezoids are formed. They are ABFE and EFCD
By comparing both trapezoids, it means that
4/15 = FC/18
Cross multiplying, it becomes
4 × 18 = 15FC
72 = 15FC
FC = 72/15
FC = 4.8

Answer:
(d) 528 ft³
Step-by-step explanation:
The shape is that of a trapezoidal prism. The front face is a trapezoid with bases 8 ft and 14 ft, and height 6 ft. Its area is ...
A = (1/2)(b1 +b2)h = (1/2)(8 +14)(6) = 66 . . . . square feet
Then the volume is given by ...
V = Bh
where B is the area of the (trapezoidal) base, and h is the height of the prism (8 ft). Filling in the values, we find ...
V = (66 ft²)(8 ft) = 528 ft³
The pool can hold 528 ft³ of water.

Answer:
2 students are in both clubs
Step-by-step explanation:
x = 1 student (this number may be more than the total because one student can be in 2 clubs)
Club a = 13
Club b = 20
13 + 20 = 27x
Total members of clubs - total number of students = 27x - 25 = 2
