Step-by-step explanation:
If the area of a rectangle is 30 cm what can the possible length and breadth of the rectangle be?
(Hint: The area of a rectangle = length x breadth)
Answer:
The length could be 6, 10, or 15 and the breadth; 5, 3 and 2 respectively
This is because, length x breadth = area
6x5=30
10x3=30
15x2=30
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.

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.

If you find a common number of hours between the two expressions such as 24 hours you will see that the pay isn't the same. $24 for 6 hours of work ($4:1hr) can be turned into $96 for 24 hours of work and $36 hours for 8 hours of work ($4.5:1) turns into $108 for 24 hours of work.
Equation 1:

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!
Find the inverse of f (x) = x + 2 + 9
Answer:
y = x - 11
Step-by-step explanation:
First, turn the f(x) into a y:
y = x + 2 + 9
Now, switch the x and y.
x = y + 2 + 9
Add like terms.
2 + 9 = 11
x = y + 11
Now, solve for y. Subtract 11 on both sides.
y = x - 11
A recipe for pie dough calls for a ratio of butter to flour of 23 : 134. If you plan to use 7 cups of flour, how much butter should you use to keep the same ratio?
Answer:
You might have to round, but ≈1.2015
Step-by-step explanation:
butter: flour
23 : 134 is really just a:b
b = 7, so: a : 7
Divide both sides by 134, so
≈0.172 : 1
Multiply by 7 to get 7 cups of flour
≈1.2:7

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

What is the cosine law?The squared of the size of any solitary side of either a triangle is equal, by the cosine rule, to the total of the squares of the lengths of the other two sides, times by the cosine of something like the angle they are a part of.
Let the triangle ΔABC, then the cosine law is given as,
c² = a² + b² - 2 a·b cos C
From the graph, the measure of the length 'x' is calculated as,
x² = 5² + 8² - 2 (5)·(8) cos 55°
The equations correctly set up the law of cosines to solve for x will be x² = 5² + 8² - 2 (5)·(8) cos 55°. Then the correct option is B.
