Answer:
The length of the side JH is approximately 31.5 feet long.
Step-by-step explanation:
There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{88} =\frac{sin(21^{o})}{x}[/tex] ⇒ [tex]\frac{88}{sin(90^{o})} =\frac{x}{sin(21^{o})}[/tex] ⇒ [tex]x = \frac{88*sin(21^{o})}{sin(90^o)}[/tex] ⇒ [tex]x=31.5ft.[/tex]
Evaluate each expression for n = 5. 6n + n2
Answer:
40
Step-by-step explanation:
1. Plug in the given value for n
6(5) + (5)2
2. Solve using PEMDAS
(I'm not sure if the 2 after the n is supposed to be squared, but if it was n^2 then the correct answer would be 55, I think)
30 + 10 = 40
Therefore, the answer is 40
Hope this helps :)
Which are rational numbers check all that are true
Answer:
All of them except the second one and third one are true .
Answer:
1/3, 3, -1/3
Step-by-step explanation:
A rational number is a number that can be expressed with a fraction. In this case we have:
1/3 , 3 (all natural numbers are also rational: in fact for example 3 can be expressed with the fraction: 3/1) , -1/3
333/0 is not a rational number because the division is impossible
√3 is not rational because can’t be expressed with a fraction
Which of the following could be the graph of y = –xn where n is odd?
Answer:
Step-by-step explanation:
I think you meant y = -x^n, where ^ denotes exponentiation.
If n is odd, the graph begins in Quadrant II and decreases through the origin into Quadrant IV. This is true of -x, -x^3, -x^5, and so on.

How do I find the measurement of Angle x?
Answer:
26°
Step-by-step explanation:
The angle 123° is on a straight line. All angles on a straight line add up to 180°, so the first thing you should do is subtract 123 from 180.
(180-123)
Now, your answer should be 57°, and that is equal to angle W.
You now know two angles. Angles in a triangle add up to 180°, too, so all you do now is the following:
97 + 57 = 154
180- 154 + 26
And there's your answer!
what's the volume of the cone
[tex] \bullet [/tex] Radius (r) of the cone is 3 ft.
[tex] \bullet [/tex] Height (h) of the cone is 9 ft.
To Find:-The volume of the cone.
Solution:-We know,
Formula of Volume of cone is [tex] \frac{1}{3} [/tex]πr²h
So, Volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × (3)² × 9
Volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × 3 × 3 × 9
Volume of the cone = [tex] \frac{22 \: × \: 3 \: × \: 3 \: × \: 9}{3 \: × \: 7} [/tex]
Volume of the cone = [tex] \frac{1782}{21} [/tex]
Volume of the cone = 84.86 cubic ft.
The volume of the cone is 84.86 cubic ft. [Answer]Im stuck on this question, can someone help:)

Help!
A bakery advertised a bag of cookies today for $3.99. Why did the bakery set the price at $3.99 instead of $4.00?
a The bakery needs to get rid of old cookies.
b The bakery wants to improve the reviews on that brand.
c Our brains tend to notice the first digit first.
d We may pay an extra penny at the register.
Answer:
C.
Step-by-step explanation:
If you think about it, it makes a little bit of sense. You pay $3.99 for the bag of cookies when the initial price was $4. To you, it sounds cheaper. But you're technically paying the same amount of cash as you would for the previous amount of cookies, as nobody in America keeps 99 cents in their pockets at all times, and 99 cents obviously rounds up to a dollar, so it's technically the same price as before. Overall, this would be essentially just a cheap marketing technique that they're using to get more money out of a larger group of people. If they're trying to get rid of old cookies, they wouldn't lower the price by just a cent, lowering the price by just a cent in order to improve the reviews might as well do the opposite, and paying an extra cent doesn't make much of a difference considering the old price. So thus the answer is C.

Elizabeth has $680 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax.
• She buys a new bicycle for $437.63.
• She buys 2 bicycle reflectors for $17.63 each and a pair of bike gloves for $18.11.
She plans to spend some or all of the money she has left to buy new biking outfits
for $35.19 each.
What is the greatest number of outfits Elizabeth can buy with the money that's left
over?
Answer: 5 outfits
Step-by-step explanation: 17.63x2=35.26
437.63+35.26+18.11=491
680-491=189
189 divided by 35.19= 5 (rounded)
What is the surface area of cereal box whose length , breath, and height are 20cm , 8cm,30cm ,also find its volume
Answer:
V = 4800 cm^3
SA = 2000 cm^2
Step-by-step explanation:
V = l x w x h
V = 20 x 8 x 30
V = 4800 cm^3
20 x 8 x 2 = 320 cm^2
20 x 30 x 2 = 1200 cm^2
8 x 30 x 2 = 480 cm^2
320 + 1200 + 480 = 2000 cm^2

Frank reverses the ordered pairs to show the heights and ages of the same six students. Is age a function of height? Explain.
The natural world is full of relationships between quantities that change. When we see these relationships, it is natural for us to ask “If I know one quantity, can I then determine the other?” This establishes the idea of an input quantity, or independent variable, and a corresponding output quantity, or dependent variable. From this, we get the notion of a functional relationship in which the output can be determined from the input. For some quantities, like height and age, there are certain relationships between these quantities. Given a specific person and any age, it is easy enough to determine their height, but if we tried to reverse that relationship and determine age from a given height, that would be problematic, since most people maintain the same height for many years.
Therefore.....age is not a function of height!!
