Answer:
x = -4
Step-by-step explanation:
x(x + 4) = 0

The number of mosquitoes in Anchorage, Alaska (in millions of mosquitoes) as a function of rainfall (in centimeters) is modeled by: m(x)=-x^2+14xm(x)=−x 2 +14xm, left parenthesis, x, right parenthesis, equals, minus, x, squared, plus, 14, x What is the maximum possible number of mosquitoes?
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
[tex]0 = -2x + 14[/tex]
Make 2x the subject
[tex]2x = 14[/tex]
Make x the subject
[tex]x = 14/2[/tex]
[tex]x = 7[/tex]

5/8
of Mrs. Jackson’s class have ear buds.
2/3
of the ear buds in her class are black. What fraction of
the scholars have black ear buds?
Answer:
5/12
Step-by-step explanation:
Total ear buds in Mrs. Jackson’s class = 5/8
Number of black ear buds in Mrs. Jackson’s class = 2/3
What fraction of
the scholars have black ear buds?
2/3 of the scholars have black ear buds in Mrs. Jackson’s class
2/3 of 5/8
= 2/3 × 5/8
= 10/24
= 5/12
Fraction of the scholars that have black ear buds = 5/12

2000x+6000=3600-40000
Answer:
x = -21.2
Step-by-step explanation:
2000x + 6000 = 3600 - 40000
2000x = -36400 - 6000
x = -42400 / 2000
x = -21.2
Hope this helped!
Answer:
x = − 106/5Step-by-step explanation:
How to solve your question
Your question is
2000x+6000=3600−40000
Subtract the numbers
2000x+6000=3600−40000
2000x+6000=−36400
Subtract
6000
60006000
from both sides of the equation
2000+6000=−36400
2000x+6000=-364002000x+6000=−36400
2000+6000−6000=−36400−6000
Divide both sides of the equation by the same term
2000=−42400
2000x=-424002000x=−42400
20002000=−424002000
\frac{2000x}{{\color{#c92786}{2000}}}=\frac{-42400}{{\color{#c92786}{2000}}}20002000x=2000−42400

Answer:
4x+9+x+17=180-29
5x+26=151
5x=125
x=25
3/4 of 24 is 3 groups of 6, which is 18. So Han ate 18 less than Tyler, or Han at 6. So you take the 24(x) and you subtract 24 of 24(-3/4x) to get to Han total.
Answer:
Step-by-step explanation:
Let the total amount ate by Tyler and Han be 24
Let the amount Tyler ate be x
Amount Han ate be y
If Tyler ate 3/4 of the total, then Amount ate by Tyler is expressed as;
x = 3/4of 24
x = 3/4×24
x = 3×6
x = 3(6)
x = 18
Hence the amount Tyler ate is 18
If Han ate 18 less than Tyler, the amount ate by Han will be;
Han y = 24-(3/4(24)
y = 24-{3(6)}
y = 24-18
y = 6
Hence the total Han ate is 6
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.

A parachute speed during a free fall reaches117 miles per hour What is the speed in feet per second At the speed how many feet will the parachute fall during 10sec in your
Answer:
Speed is 171.6 ft/s and distance is 1716 feet
Step-by-step explanation:
Given that,
The speed of a parachute = 117 miles per hour.
1 mph = 1.47 ft/s
117 mph = 171.6 ft/s
We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,
d = vt
[tex]d=171.6\ ft/s\times 10\ s\\\\=1716\ \text{feet}[/tex]

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.

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.
