Answer:
[tex]-3^{\circ \:}x\left(-3\right)=\left(-3\right)\cdot \:14 : x = \frac{840}{180^{\circ \:}}[/tex]
Decimal Form:
[tex]x = -267.38030...[/tex]
Step-by-step explanation:
[tex]-3^{\circ \:}x\left(-3\right)=\left(-3\right)\cdot \:14[/tex]
Remove Parentheses: [tex](-a) = -a[/tex]
[tex]-3^{\circ \:}x\left(-3\right)=-3\cdot \:14[/tex]
Multiply the numbers: [tex]3 * 14 = 42[/tex]
[tex]-3^{\circ \:}x\left(-3\right)=-42[/tex]
Divide both sides by: [tex]-3^{\circ \:}\left(-3\right)[/tex]
[tex]\frac{-3^{\circ \:}x\left(-3\right)}{-3^{\circ \:}\left(-3\right)}=\frac{-42}{-3^{\circ \:}\left(-3\right)}[/tex]
Simplify:
[tex]x=-\frac{840}{180^{\circ \:}}[/tex]

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]
-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
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]

8 ft
/8 ft
6 ft
6 ft
8 ft
144f
9514 1404 393
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.

Find the area of the trapezoid.
The trapezoid has an area of
m2.
4 m
1
16m
-
-
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].
Answer:
first one right
Step-by-step explanation:
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
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".

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.

If there are 13 people in club a and 20 people in club b and 25 students in total, how many people are in both clubs?
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
2 students are in both clubs

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

- 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.
