Answer:
Option
B $146
Step-by-step explanation:
Step one:
given data
An airport parking lot charges a basic fee of $2 plus $1 per half-hour
this means that for 30 mins the airport will charge an extra $1
hence for 1 hour they will charge $2
so, let the total charge be y and the number of time be x
Step two:
The expression for the situation is given as
y= 2+2x
for x= 72hours
y= 2+72*2
y=2+144
y= $146
Answer:
the answer it 146

----------- = 30/50 = 0.6
50
answer:
- the change is an increase by 60%
Answer:
increase of 60%
Step-by-step explanation
The change from 50 to 80 is an increase of 30
To calculate percentage increase
[tex]\frac{change}{original}[/tex] × 100%
= [tex]\frac{30}{50}[/tex] × 100%
= 60% increase

Step-by-step explanation:
A 3-foot-wide wood deck will be built around a rectangular-shaped pool that measures 15 feet by 30 feet. The resulting shape is also rectangular. If the lumber costs $10 per square yard, If the lumber costs 10 dollars per square yard, what is the cost of the wood for the deck?
Answer:
$340
Step-by-step explanation:
We are told that the pool measures 15 feet by 30 feet,
Since the cost of the wood around it is per yards, let's convert this measurement to yards.
15 ft = 5 yards
30 ft = 10 yards
The deck is 3 ft wide. Converting to yards it is 1 yard.
Since the deck is round the pool, it means when we add it to the pool dimensions, we now have a dimension of; width: 7 yards by length: 12 yards
Thus, total area of pool and deck is;
A_t = 7 × 12 = 84 Sq.yds
Area of only pool is;
A_p = 5 × 10 = 50 Sq.yds
Finally, area of the deck will be;
A_d = 84 Sq.yds - 50 Sq.yds = 34 Sq.yds
We are told that the costs of the wood is $10 per Sq.yds
Thus, total cost is;
C = 10 × 34
C = $340

Please help im not smart at all lol
Answer:
1/2 ( 10x + 8 )
Step-by-step explanation:
first make sure everything in the parenthesis is addition. by doing this you make the 6 and 8x negatives. so it's 1/2 ( 13x + 5x + -6 + -8 + 14 ) then combine the numbers with the variable x so 13x + 5x + -8x = 10x . then the ones without variables -6 + 14 = 8. so 1/2 ( 10x + 8)
A leaf is falling from the top of a tree. The height of the leaf in feet, y, can be found using the function y = -3.5x + 28, where x is the time in seconds the leaf has been in the air. How many seconds did it take the leaf to reach the ground?
Answer:
It took 8 seconds for the leaf to reach the ground.
Step-by-step explanation:
The height of the leaf in feet can be found using the function:
y = -3.5*x + 28
where x is the time in seconds the leaf has been in the air.
You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:
0= -3.5*x + 28
and solving you get:
-28= -3.5*x
(-28)÷ (-3.5)=x
8=x
It took 8 seconds for the leaf to reach the ground.
Equation 1:
X-3 = 2-4x
Which of these have the same solution as Equation 1?
Explain your reasoning.
Equation A:
2x-6 = 4-8x
Equation B:
X-5 = -4x
I
Equation C
2(1-2x) = x-3
Equation D:
-3 = 2-5x
Answer:
since equation 1 says that X= 1
any other equation saying x=1 will be valid!
Equation A
Equation B
Equation C
Equation D
all correct
You have $4.10 and would like to buy some almonds .if a pond costs $8, how many ounces can you buy ?
Answer:
Step-by-step explanation:

The angle of elevation to an airplane viewed from the control tower at an airport is 15°. The tower is 100 feet high and Pilot Cory reports that the altitude of the airplane is 5100 feet (5000 feet higher than the control tower). How far away (ground distance) from the control tower is the airplane?
Answer:
Given: Angle of elevation 15°AB (height of tower)=100AE=?CE = 5100 (5000 feet heigher than the tower)Now,
tan15°=
[tex] \frac{5100}{ae} [/tex]
ae=
[tex] \frac{5100}{tan15} [/tex]
.: ae = 19033.45
.: the aeroplane is 19033.45 m away from the control tower.
which equation is parallel to the line y= -5/7x - 7
Answer:
5x + 7y = -42
Step-by-step explanation:
This question will be a little easier to answer if we change the form of the original equation from slope intercept to standard form:
[tex]y=(-5/7)x-7\\(5/7)x+y=-7\\5x+7y=-49[/tex]
All parallel lines have the same slope, but what does that mean when our equation's in standard form. Well, slope only depends on the coefficients of the x and y terms, so any equation of a line in standard form with 5x + 7y on the left side will be parallel to the one in the problem. Looking through the possible choices, B. 5x + 7y = -42 is the only one that works.
Using desmos to check our work, we can see that the two lines are actually parallel!
What is area of circle that has circumference of 12pi
Answer:
36pi
Step-by-step explanation:
Since the formula for the circumference is C=2*pi*r
12pi=2*pi*r we can divide and get r=6 cm
Then, we can use the formula for the area of a circle: Area=pi*r^2 and get Area=pi*6^2=36*pi.
