Answer:
Step-by-step explanation:
Given that:
A professional climber makes his way up to 828 meters in 6 hours in Burj Khalifa.
Therefore; in two hours, he would have climbed:
x = (828 m × 2hrs)/6 hrs
x = 276 miles
In five hours, he would have climbed;
y = ( 828 m × 5 hrs)/6 hrs
y = 690 miles
SInce 60 minutes = 1 hour
Then 15 minutes will be ( 15)/60 = 0.25 hours
Thus, in the last 15 minutes;
He climbed = (828 m × 0.25 hrs)/6 hrs = 34.5 miles

Each unit on the map represents 1 mile. To the nearest tenth of a mile, what is the distance from the
library to the supermarket?
Answer:
5.8 miles
Step-by-step explanation:
Distance of library(3, 2) to the supermarket (6, 7) using distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Where,
[tex] (3, 2) = (x_1, y_1) [/tex]
[tex] (6, 7) = (x_2, y_2) [/tex]
Plug in the values into the formula
[tex] d = \sqrt{(6 - 3)^2 + (7 - 2)^2} [/tex]
[tex] d = \sqrt{(3)^2 + (5)^2} [/tex]
[tex] d = \sqrt{9 + 25} [/tex]
[tex] d = \sqrt{34} = 5.8 miles [/tex] (nearest tenth).

Karra is at the dollar store buying bags of chips for her sleepover party. For every 5 bags of chips she buys, she pays $6. What is the price per bag of chips? *Money always has two numbers after the decimal.
Answer:
$1.20
Step-by-step explanation:
Given that:
Price paid to buy 5 bags of chips = $6
To find:
Price per bag of chips in two digits after the decimal.
Solution:
To find the price of each bag of chips, we need to divide the price of 5 bags of chips with 5.
i.e. we need to divide $6 with 5, then we will get the price of each bag of chips.
[tex]\text{Price of each bag of chips}=\dfrac{\text{Price of 5 bags of chips}}{5}\\\Rightarrow \dfrac{\$6}{5} = \bold{\$1.2}[/tex]
Therefore, the answer is:
Price of each bag of chips is $1.2.

Answer:
95%
Step-by-step explanation:
Answer:
95%
Step-by-step explanation:
Multiply both 80 and 76 by 100, to get 800 and 760. Then divied both by 8 to get 100 and 95. 95 is 95% of 100, and so 76 is 95% of 80. Hope this helps!

Step-by-step explanation:
Suppose the man in the St. Ives poem has x wives, each wife has x sacks, each sack has x cats, and each cat has x kits. Write an expression using exponents that represents the total number of kits, cats, sacks, and wives going to St. Ives.
Answer: [tex]x+x^2+x^3+x^4[/tex]
Step-by-step explanation:
As per given,
Number of wives = [tex]x[/tex]
Number of sacks = [tex]x (\text{Number of wives} )= x\times x = x^2[/tex]
Number of cats = [tex]x(\text{Number of sack})[/tex][tex]= x \times x^2=x^3[/tex]
Number of kits = [tex]x(\text{Number of cats} )=x\times x^3=x^4[/tex]
Now , the total number of kits, cats, sacks, and wives going to St. Ives = [tex]x+x^2+x^3+x^4[/tex]
Hence, the required ex[pression: [tex]x+x^2+x^3+x^4[/tex]
Two sides of an obtuse triangle measure 9 inches and 14 inches. The length of longest side is unknown. What is the smallest possible whole-number length of the unknown side? 16 inches 17 inches 24 inches 25 inches
Answer:
17 inches
Step-by-step explanation:
An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.
Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.
Now we know that for an obtuse triangle,
[tex]$c^2 > a^2 +b^2$[/tex]
[tex]$c^2 > (9)^2 +(14)^2$[/tex]
[tex]$c^2 > 81 +196$[/tex]
[tex]$c^2 > 277$[/tex]
c > 16.64
Therefore the smallest possible whole number is 17 inches.
It should be noted that the length of the unknown side will be 17 inches.
From the information given, we are informed that the sides of an obtuse triangle measure 9 inches and 14 inches.
Therefore, the third side will be:
c² = 9² + 14²
c² = 81 + 196
c² = 277
c = ✓277
c = 16.64
c = 17
In conclusion, the correct option is 17 inches.

8. The value of y is directly proportional to the value of x. If y = 35 when x = 140, what is the value of y when x = 70? Record your answer and fill in the bubbles on your answer document.
Answer:
y = 17.5
It says y is proportional to x, and y = 35 when x = 140, but we don't know what y is when x = 70. So since y is proportional to x and x = 140 we have to find out how 140 gets to 70, and that is dividing by 2 because 70 is half of 140. So then you would just divide the previous y value, 35, by 2, and you would get 17.5. And there you go, you've got you're answer.

Answer:
The maximum number of mosquitoes is 7
Step-by-step explanation:
Given
[tex]m(x)= x^2 + 14x[/tex]
Required
Determine the maximum number of the function
First, we differentiate the given function w.r.t x
[tex]m'(x) = -2x + 14[/tex]
Then, we equate m'(x) to 0
[tex]0 = -2x + 14[/tex]
Lastly, we solve for x
