Answer:
I'm pretty sure it's D.40 because it's the biggest number and 6+13+17 is only a bit bigger than 24. Also, all the numbers add up to 60 and 27 is only a bit less than 50% of 60
A quarter falls off a building that is 144
feet tall. If the equation for height as a
function of time is
h(t) = -16t2 + initial height where t is
time in seconds and h(t) is height in
feet, how many seconds will it take for
the quarter to hit the ground?
Answer:
3 seconds
Step-by-step explanation:
Initial height = 144 feet
t = Time taken
The equation of the height from the ground is
[tex]h(t)=-16t^2+\text{Initial height}[/tex]
The time taken to reach the ground is needed. Here the ground is taken as reference so [tex]h(t)=0[/tex]
[tex]0=-16t^2+144\\\Rightarrow -144=-16t^2\\\Rightarrow t=\sqrt{\dfrac{144}{16}}\\\Rightarrow t=3\ \text{s}[/tex]
So, time taken by the quarter to reach the ground is 3 seconds.
can anyone help me pls? i will give brainliest :)
EFGH is a parallelogram. Find the measure of FG and EG
Answer:
FG = 44
EG = 80
Step-by-step explanation:
For FG:
1) 5z - 16 = 3z + 8
2) 5z = 3z + 24
3) 2z = 24
4) z = 12
5) 3(12) + 8 = 44
For EG:
1) 2w + 22 = 4w + 4
2) 2w = 4w - 18
3) -2w = -18
4) w = 9
5) 4(9) + 4 + 2w + 22 = 80
Pls help!! I can’t understand this
Answer: The answer is 4 units to the left of 11
Step-by-step explanation: First you get the answer -4+11=7 so then on the number line you have to find which of those options gets you 7 which will be 4 units to the left of 11 since the left is going less then 11 in the end you will get 2 places more to the right of the 5 on the number line making the number 7 there.
jay has an album that holds 600 coins. Each page of the album holds 6 coins. If 39% of the album is empty, how many pages are filled with coins ?
____ pages are filled with coins
Pls help me with this
9514 1404 393
Answer:
61
Step-by-step explanation:
If there are 6 coins on each page, then the number of pages for 600 coins is ...
(600 coins)/(6 coins/page) = 100 pages
__
If 39% are empty, then 100% -39% = 61% are filled.
The number of filled pages is ...
61% × 100 = 61/100 × 100 = 61 . . . . pages filled
_____
Comment about percent
You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100
("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)
Deduce the minimum value of sinx+cosx and give the corresponding values of x, for x E [-360;360]
The minimum value of both sine and cosine is -1. However the angles that produce the minimum values are different, [tex]-\pi/2, \pi[/tex] for sine and cosine respectively.
The question is, can we find an angle for which the sum of sine and cosine of such angle is less than the sum of values at any other angle.
Here is a procedure, first take a derivative
[tex]\frac{d}{dx}(\sin x+\cos x)=\cos x -\sin x[/tex]
Then compute critical points of a derivative
[tex]\cos x-\sin x=0\implies x_1=\frac{\pi}{4},x_2=\frac{5\pi}{4}[/tex].
Then evaluate [tex]\sin x +\cos x[/tex] at [tex]x_1,x_2[/tex].
You will obtain global maxima and global minima [tex]\sqrt{2}, -\sqrt{2}[/tex] respectively.
The answer is [tex]-\sqrt{2}[/tex].
Hope this helps.

Step-by-step explanation:
Show that 2/4-x = 10/4+x
is equivalent to 12x = 32 for all values of x not equal to 4 or -4
Answer:
See proof below
Step-by-step explanation:
Given the expression 2/4-x = 10/4+x
Cross multiply
10(4-x) = 2(4+x)
10(4) - 10x = 2(4)+ 2x
40 - 10x = 8 + 2x
-10x - 2x = 8 - 40
-12x = -32
Multiply both sides by -1
-1(-12x) = -1(-32)
12x = 32
This shows the required expression

what is 2/3(9+x)=-5(4-x)
Answer:
x=78
Step-by-step explanation:
2/3(9+x)=-5(4-x)
6+2/3=-20+x
6=-20+1/3x
x=78
Answer:
x=6
Step-by-step explanation:
Distribute.
2/3 * 9 = 6
2/3 * x = 2/3x
Distribute other side.
-5*4 = -20
-5 * -x = 5x
Rewrite.
6 + 2/3x = -20 + 5x
Subtract 5x from both sides.
-13/3x + 6 = -20
Subtract 6 from both sides.
-13/3x = -26
Multiply -3/13 to both sides.
x=6
-3 > t+5/-1

HELP WILL GIVE BRAINLIST: Answers A: $26.81 b: $22.98 c: $19:98 D $3.83
Answer:
B 22.98
Step-by-step explanation:
divided 11.49 by 3, you get 3.83, then multiply it by 6. thats your answer
Answer:
B: $22.98
Step-by-step explanation:
The first thing we need to do for this question is find a pattern. Find a pattern between the prices of 3 pizzas, 4 pizzas, and 5 pizzas. Once we have this pattern, we can solve for x.
To find the pattern, we must first subtract the price of 4 pizzas from the price of 3 pizzas. This difference is 3.83, so we know the price went up $3.83. Next, subtract the price of 5 pizzas from the price of 4 pizzas. This is also 3.83, so we know that for every extra pizza added, the price goes up $3.83.
Now that we have our pattern, we can solve for x. Because the price goes up $3.83 for every extra pizza added, we can add $3.83 to the price of 5 pizzas. This will give us $22.98. We now know the value of x and the price of 6 pizzas.
I hope this helps. Please let me know if you need any more help. Have a great day and good luck!

Answer:
56.1
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos N = PN / NO
cos 27 = 50/ x
x cos 27 / 50
x = 50/cos 27
x=56.11631188
Rounding to the nearest tenth
x = 56.1

Given that ABCD ~ EFGH, find the value of x
Answer:
x = 8
Step-by-step explanation:
Recall: Ratio of the corresponding side lengths of two similar figures are equal.
Therefore,
EF/AB = GH/CD
6/4 = 12/x
Cross multiply
6*x = 12*4
6x = 48
Divide both sides by 6
6x/6 = 48/6
x = 8

B. 186 square units
C. 131 square units
D. 66 square units
Answer:
○ B. [tex]\displaystyle 186\:square\:units[/tex]

What is the value of the interquartile range of the data below?
25

35
40
45 50
Answer:
5
Step-by-step explanation:
The value of the interquartile range of the data below is 5.
What is Interquartile Range?The difference between the third and the first quartile is defined by the interquartile range. There are so three quartiles.
The first quartile, also known as the lower quartile, is marked by Q1, the second quartile by Q2, and the third quartile, sometimes known as the upper quartile, is denoted by Q3. The lower quartile less the upper quartile equals the interquartile range.
From the Plot we can write
Minimum = 27
Lower quartile = 32
Median = 36
Upper Quartile = 37
Maximum = 40
So, Interquartile range (IQR)
= Third Quartile (Q3) - First Quartile (Q1)
= 37 - 32
= 5
