I don't know what the dropdown menus are, but Mike is half-correct. The opposite of a number is the number with the opposite sign, so the opposite of 5 is -5. But the absolute value of a number is its distance from zero on a number line, and distances can't be negative, so the absolute value of 5 is 5, not -5.
Li Na is preparing for a party. She will have at least 100 guests attending. The venue has small tables that seat 4 people and large tables that seat 6 people.
Write an equation or inequality to represent how many small and large tables Li Na could use
to seat all her guests.
Answer: 100 = 4x + 6y
Step-by-step explanation:
We have a total of 100 guests, small tables seat 4, and large tables seat 6. So for each small table used, 4 guests are subtracted from the total.
x = small tables
y = large tables

We have to calculate the number of seconds for the flare to return to the sea.
We have an initial vertical speed of 448 ft/s.
The only force acting on the flare is gravity.
Then, we can model the heigth in function of time using the equation:
[tex]h(t)=h_0+v_yt-\frac{g}{2}t^2[/tex]where h0 = 0 ft, vy = 448 ft/s and g = 32 ft/s².
Then, we can replace and calculate t for h(t) = 0, that is the time it took the flare to come back to the initial height (that is 0 ft):
[tex]\begin{gathered} h(t)=0 \\ h_0+v_yt-\frac{g}{2}t^2=0 \\ 0+448t-\frac{32}{2}t^2=0 \\ 448t=16t^2 \\ 448=16t \\ t=\frac{448}{16} \\ t=28 \end{gathered}[/tex]Answer: it will take 28 seconds for the flare to return to the sea [Third option].

Choose by clicking the graph. Find <0 if sec0= -13/5 and tan0 is negative
Using the definition of the secant, the angle is given as follows:
θ = 112.6º.
How to calculate the secant of an angle?The secant of an angle θ is given by one divided by the cosine of the angle θ, that is:
sec(θ) = 1/cos(θ).
In the context of this problem, the numeric value of the secant of the angle is given as follows:
sec(θ) = -13/5.
This means that the following relation can be established:
1/cos(θ) = -13/5.
Hence we can solve to find the angle measure as follows, applying cross multiplication:
-13cos(θ) = 5
cos(θ) = -5/13.
Applying the inverse cosine, we have that:
θ = arccos(-5/13).
θ = 112.6º.
This angle has equivalent on other quadrants, as for example, in the third quadrant the cosine is also negative. However, in the third quadrant, the tangent is positive and we want a negative tangent, which is why the measure is of θ = 112.6º.

To make coffee, one small scoop of coffee grounds is added to 2 cups of water. You can draw a ratio table or make a proportion to help find how many cups of water to use for 5 scoops of coffee.
The proportional relation:
y = 2*x
Tells us how many cups of water we need for x scoops of coffee, with this we can see that for 5 scoops we need 10 cups.
How many cups of water do we need for 5 scoops of coffee?We know that for one small scoop of coffee, you need to add 2 cups of water. Then we can write the proportional relation:
y = 2*x
Where x is the number of scoops of coffee and y is the number of cups of water.
if x = 5, then:
y = 2*5 = 10
y = 10
So for 5 scoops of coffee, you need 10 cups of water.

A skydiver is planning her jump out of an airplane. Typically, she will jump at a height
of 13,500 feet and she will pull the cord when she is 5000 feet above the ground. If the
equation for distance traveled during freefall is given as d(t) = 16t², how long should
she wait before pulling the cord?
If she will jump at a height of 13500 feet and she will pull the cord when she is 5000 feet above the ground, the equation for distance traveled during freefall is d(t)= [tex]16t^{2}[/tex], then she has to wait 23.05 seconds to pull the cord
The initial height = 13500 feet
The height at which she has to pull the cord = 5000 feet above the ground
The distance traveled to reach 5000 feet above the ground = 13500-5000
= 8500 feet
The equation for the distance traveled during the freefall d(t)= [tex]16t^{2}[/tex]
where d is the distance traveled
t is the time taken
Substitute the values in the equation
8500 = 16 × [tex]t^{2}[/tex]
[tex]t^{2}[/tex] = 8500/16
[tex]t^{2}[/tex] = 531.25
t = [tex]\sqrt{531.25}[/tex]
t = 23.05 seconds
Hence, If she will jump at a height of 13500 feet and she will pull the cord when she is 5000 feet above the ground, the equation for distance traveled during freefall is d(t)= [tex]16t^{2}[/tex], then she has to wait 23.05 seconds to pull the cord

EXPLANATION:
Prior Knowledge Problems:
1. On the first math test, Jamaya
answered 19 out of 25 questions
correctly. On the second test she got
17 out of 20 correct. On which test did
she get a better grade?
a. Write a ratio in fraction form to
compare the number correct to the
total questions for each test.
b. Can you compare these two ratios
as they are written?
a) Ratio in fraction form to compare the number correct to the total questions for each test is [tex]\frac{17}{20}[/tex].
b) Yes, we compare these two ratios as they are written.
How to calculate the above question?Jamaya got a better answer on the test on her second test, and you could compare these two ratios as they are written.
a)
First: Convert the each of scores into the percentages:
How do you convert the ratios to percentages? Well, first we have to convert ratio to a decimal or a fraction. Let's convert it to fraction. So, 19 out of 25 will become fraction [tex]\frac{19}{25}[/tex], and 17 out of 20 will become fraction [tex]\frac{17}{20}[/tex] . To convert fraction to percentage:
Divide numerator by denominator:
19 ÷ 25 = 0.76 AND 17 ÷ 20 = 0.85
Multiply the quotient by 100
0.76 x 100 = 76 AND 0.85 x 100 = 85
Add percent sign
76% AND 85%
Now, two quantities are easier to compare. We can obviously see that 85% is the bigger [and better] than 76%. So, ratio that equals 85% - 17 out of 20 - is a better grade.
b)
Yes, you can compare the these two ratios, just find [positive] difference between the amount that she scored and the total number of scores that could be gained.
25 - 19 = 6
20 - 17 = 3
Since equation with 20 and 17 in it has a smaller difference, it is most likely to have a greater value [because that means that Jamaya got more right and less wrong, which means a greater mark which is also greater quantity].

How to simplify the given expression?Here we have the mathematical expression:
[tex]\frac{(5 + \sqrt{3})*(5 - \sqrt{3} ) }{\sqrt{22} }[/tex]
Remember the rule:
[tex](a + b)*(a - b) = a^2 + b^2[/tex]
Then the numerator can be rewritten as:
[tex]\frac{(5 + \sqrt{3})*(5 - \sqrt{3} ) }{\sqrt{22} } = \frac{5^2 - \sqrt{3}^2 }{\sqrt{22} } = \frac{25 - 9}{\sqrt{22} } = \frac{16}{\sqrt{22} }[/tex]

The image of the setting sun most likely not described in great detail in "Because I Could Not Stop for Death" because it is a common symbol of death that requires little description.
Emily Dickinson's lyrical poem "Because I could not stop for Death" was originally printed in Poems: Series 1 in 1890, after her death. We don't know if Dickinson finished "Since I could not stop for Death" or if it was "abandoned" because her writing was never granted permission to be published.
In the poem "Because I could not stop for death the personified Death appears to Dickinson's poem's speaker. The poet's character speaks calmly about Death, the Afterlife, and the tranquility that comes with it. She represents Death as a young guy accompanying her in a carriage. She gives us a quick overview of her previous life while still living as she passes through to the afterlife.

If a scale of a map is 1:10000 what will be the length on this map of a road which is 5 km long?
Step-by-step explanation:
1:10000
means we are using the same metric on the map and in reality.
just 1 unit in the map corresponds to 10000 units in reality.
so, e.g. 1 cm on the map = 10000 cm in reality.
1 m = 100 cm
so, 10000 cm = 100 m.
therefore, 1 cm on the map = 100 m in reality.
but we need 5 km = 5000 m.
that is 50 times 100 m in reality or 1 cm on the map.
so, the length on the map is 50 cm.
