Jackson’s backpack weighs 734 pounds. After he adds food and water to his backpack, it weighs 1134 pounds. If the water weighs 134 pounds, how much does the food weigh?
Answer: 266 lbs.
Step-by-step explanation:
First, you subtract 734 from 1134 to get 400. Then, you subtract the number of pounds the water weighs from how much the food and water weighs. So you basically do 400 - 134 to get 266.

Answer:
16850.58 (2DP)
Step-by-step explanation:
Compound Interest Formula = P(1 + [tex]\frac{r}{100}[/tex])^t
P = 10,000
Rate = 11%
Time = 5 years
10000(1.11)^5 = $16850.58
Big Red Gymnastics Academy charges an initial fee of $ 200 to rent its gym for birthday parties. The academy then charges an additional $75 per hour. Write an equation that gives the total cost of the gym as a function of gym time (in hours).
A. y= 75x - 200
B. y= 200x + 75
C. y= 75x + 200
D. y= 200 - 75x
Answer: C. y= 75x + 200
Step-by-step explanation:
Since they charge $75 an hour x represents the house and they charge an initial fee of $200 so you add that to the $75 an hour
Answer:
C
Step-by-step explanation:
The equation y = mx + b helps use to solve this type of problem
We know the initial amount to rent the gym is $200, that will be our b for this case since it is the y-intercept. This is the y-intercept since that is the initial amount.
The slope for this equation will be 200 represented by m. The key term that represents this is out slope is per. "$75 per hour." Since the function is in hours we don't need to convert hours into another unit.
Now if we plug in the variables, we get the equation y = 75x + 200 which is what C is.

Answer:
112%
Step-by-step explanation:
percentage change value formula
c2 = X2 - X 1 X 100
X1 1
WHERE,
C2 = RELATIVE VALUE
X2 = FINAL VALUE ( TODAY'S VALUE) = 32,860
X1 = INITIAL VALUE (1992 VALUE) = 15,500
PERCENTAGE CHANGE = 100
C2 = 32860 - 15500 X 100
15500 1
= 17, 360 X 100
15,500 = 1.12 X 100 = 112%.

d. Using the diagram at the right,
determine the measure of AEC,
DEB, and CEB if x = 23°. Show
all your work.
Answer:
AEC=BED=157°
Step-by-step explanation:
AEC + CEB + BED + x = 360°
since CEB and x are vertical angles, they are equal.
Also, AEC = BED (same reason)
therefore,
2AEC+ 23° + 23° = 360°
2AEC + 46° = 360°
2AEC = 360° - 46°
2AEC = 314°
AEC = 157°
BED also = 157°
Nancy and Elsa like to ride bikes. The equation m=12h represents the approximate number of miles m Nancy bikes in h hours. The equation m=9h represents the approximate number of miles m Elsa bikes in h hours. How much longer will it take Elsa to bike 72 miles than Nancy?
Answer:
2 hours
Step-by-step explanation:
substitute m = 72 into both equations and solve for h
72 = 12h ( divide both sides by 12 )
6 = h
Takes Nancy 6 hours to cycle 72 miles
72 = 9h ( divide both sides by 9 )
8 = h
Takes Elsa 8 hours to cycle 72 miles
Elsa takes 2 hours longer than Nancy to cycle 72 miles
Answer:
2
Step-by-step explanation:
Answer:
2 hours
Step-by-step explanation:
substitute m = 72 into both equations and solve for h
72 = 12h ( divide both sides by 12 )
6 = h
Takes Nancy 6 hours to cycle 72 miles
72 = 9h ( divide both sides by 9 )
8 = h
Takes Elsa 8 hours to cycle 72 miles
Elsa takes 2 hours longer than Nancy to cycle 72 miles
A wire is attached 35 feet above the ground to a telephone pole. The wire makes an angle of 45° with the ground, as shown below. What is the length of the wire?
Answer:
The length of the wire will be 44.83 feet.
Step-by-step explanation:
From the information given, the wire is attached from the top of a 30 foot telephone pole to a stake in the ground. if the angle formed by the wire and the pole is 48°.
Therefore, the length of the wire will be:
cos 48° = 30/x
x = 30/cos 48°
x = 44.83
The length is 44.83 feet.
Length of the wire is equals to 35√2 feet.
What is angle of elevation?"Angle of elevation is defined as the angle between the horizontal plane and the line drawn through the point of observation."
Formula used
sinθ = (Opposite side) / Hypotenuse
According to the question,
Given,
Length of the pole = 35feet
Angle of elevation = 45°
Length of the wire = Hypotenuse
'l' represents the length of the wire
Substitute the value in the formula we get,
sin 45° = (35 / l )
⇒ (1 / √2) = (35 / l )
⇒l = 35√2 feet
Hence, length of the wire is equals to 35√2 feet.

The point StartRoot x EndRoot is plotted on the number line. A number line going from 9. 8 to 10. 7. StartRoot x EndRoot is plotted slightly to the left of 10. 2. What whole number best approximates the value of x? 100 102 103 104.
Function assigns the value of one set to another. The whole number that best approximates the value of x is 10.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given that the point √x is plotted on the number line. therefore, the value of x is in square root. Now, in order to get a whole number out of this point function, we need the value of x should be such that when it goes through the function the outcome must be a whole number. therefore, let's substitute the value of x in the function,
A.) 100
[tex]\sqrt{x} = \sqrt{100} = 10[/tex]
B.) 102
[tex]\sqrt{x} = \sqrt{102} = 10.099[/tex]
C.) 103
[tex]\sqrt{x} = \sqrt{103} = 10.149[/tex]
D.) 104
[tex]\sqrt{x} = \sqrt{104} = 10.198[/tex]
As we can see, when the value of x is 100, only then the outcome of the point function is a whole number.
Hence, the whole number that best approximates the value of x is 10.

What is the average rate of change of f over the interval [1,6] ?
Answer:34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ], thus
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8

Find the cost of leveling a badminton court 132m long and 58 m broad at the rate of Rs. 80 per sq. m.
Answer:
Rs. 612,480
Step-by-step explanation:
Hi there,
Here the question asks us to find the cost of leveling a badminton court at the rate of Rs.80 per sq..
So by the word leveling we know that we have to find the area of the court in order to proceed further.
(I am assuming the court to be rectangular in shape).
Area of a rectangle = Length * Breadth
*Length = 132 meters
*Breadth = 58 meters
==> 132*58= 7656 m^2
So now that we got the area of the badminton court lets find the cost of leveling it ==>
Cost of leveling per meter^2 = Rs. 80
Area = 7656 m^2
==> 7656 * 80 = 612,480
So the cost would be Rs. 612,480
