Answer:
25
Step-by-step explanation:
Given the function that represents the amount of mosquitoes as;
M(x) = -(x-5)² + 25
To get the maximum mosquitoes possible, we need to first find x;
At the maximum dM/dx = 0
dM//dx = -2(x-5)
0 = -2(x-5)
-2(x-5) = 0
-2x + 10 = 0
-2x = -10
x = 10/2
x = 5
Substitute x = 5 into the function;
M(5) = −(5−5)² +25
M(5) = 0+25
M(5) = 25
Hence the maximum number of mosquitoes is 25
Answer:
25 Million Mosquitoes

The equation is 15*w*14 = 2730
We simply multiply length, width and height to get the volume of the rectangular block.
That equation becomes 210w = 2730 because 15*14 = 210
From here, we divide both sides by 210
You should end up with w = 13
As a check, 15*w*14 = 15*13*14 = 2730 which confirms we have the correct replacement for w.
Tenemos 2 garrafas una al 20% y otra al 30%. Cual es su capacidad de las garrafas si tenemos 12 litros de agua
Answer:
Cada garrafa tiene una capacidad de 24 litros.
Step-by-step explanation:
Tenemos dos garrafas, definamos V como el volumen que cada garrafa tiene.
Sabemos que una de las garrafas tiene el 20%, entonces el volumen de agua que tiene esta garrafa es:
(20%/100%)*V
Y la otra garrafa tiene el 30%, entonces esta garrafa tiene:
(30%/100%)*V
El volumen total de agua es la suma de esos dos volúmenes, que nos da:
(20%/100%)*V + (30%/100%)*V
Y sabemos que tenemos 12 L de agua, entonces podemos escribir la ecuación:
12 L = (20%/100%)*V + (30%/100%)*V
Ahora podemos resolver esto para V.
12L = 0.2*V + 0.3*V
12L = 0.5*V
12L/0.5 = V
24L = V
Cada garrafa tiene una capacidad de 24 litros.
1. Find measure of angle GBC
A. 55°
B. 125°
C. 45°
D. 60°
(Show work)
Answer:
A. 55°
Step-by-step explanation:
So the line goes through two angles, 125° and 55°
Lets check, does the angle look larger than 90°
Remember, 90° mean the line is perpendicular, or goes straight up.
I see that it is not. The angle that is less than 90° (55°) is correct.
If my answer is incorrect, pls correct me!

Select the letter that correctly identifies the base of the prism.
The letter that correctly identifies the base of the prism is "a".
The prism shown in the above diagram is a triangular prism.The two distinctive sides that give a prism its name are its bases.So, the base of the prism should be in the shape of a triangle.The faces "b", "c", and "d" are rectangular, so they can not be the base of the prism.The faces "a" and "e" are triangular, so they are both the bases of the prism.Checking the options, we conclude that face "a" is the base of the given prism.Thus, the letter that correctly identifies the base of the prism is "a".To learn more about prisms, visit :

Jasper drinks a total of 1,500 ML of water every day. How many days would it take Jasper to drink 9L of water?
Answer:
6 days
Step-by-step explanation:
1 L has 1,000 mL
therefore you can create a proportion:
1500 mL / 1 = 9000 mL / d
cross-multiply to get:
1500d = 9000
d = 90/15 or 6

Classify the following triangle. Check all that apply
8.4
A. Equilateral
B. Acute
C. Obtuse
D. Scalene
E. isosceles
F. Right
Answer:
E and F but read below.
Step-by-step explanation:
I'm reading the legs as 6 and 6 so the triangle is at least isosceles.
The question is, is it also a right angle? If it is, then the Hypotenuse is incorrectly rounded. When you calculate the hypotenuse, it comes to 8.485 which should be rounded to 8.5
Regardless of that, I think the answer is intended to by a right triangle, but don't be surprised if your marker does not agree.

(c) Which number, 10, 11, or 12, will solve the equation in Part (b)? Show your work.
(d) How many pounds of potting soil did Emmanuel buy last week?
Answer:
plz help me I beg you
Answer:
1.) Amount of potting soil purchased last week.
2) 2p + 4 = 28
3.) 12 lbs
Step-by-step explanation:
1.) The unknown information is what we intend to find out using the information given, which is the amount of potting soil Emmanuel bought last week.
2.)
Let amount of potting soil bought last week = p
Amount bought this week = 2p + 4
Since amount bought this week = 28
Hence, we have ;
28 = 2p + 4
28 - 4 = 2p
24 = 2p
p = 24 / 2
p = 12
If a six-sided die(1-6) and a ten-sided die(1-10) are rolled simultaneously, then what is the probability of rolling both with a number greater than four
Answer:
[tex]Pr = 0.20[/tex]

Given
[tex]n_1 = 10[/tex] ---- 10 sided
[tex]n_2 = 6[/tex] --- 6 sided
Required
[tex]P(x_1,x_2 > 4)[/tex]
First, list out the sample space
[tex]S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)[/tex]
[tex](3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)[/tex]

Answer:
y= -2x
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -4- -2)/(2-1)
= ( -4+2)/( 2-1)
-2/1
-2
Using y = mx+b where m is the slope and b is the y intercept
y = -2x+b
Substitute a point into the equation
-2 = -2(1)+b
-2 = -2+b
b=0
y= -2x

Answer:
4845
.020639% (or 1/4845)
Step-by-step explanation:
For the first one we have to use combinations (because the order doesn't matter)
The formula is as follows:
for ACB
[tex]\frac{A!}{(A-B)!*B!}\\\\\frac{20!}{(20-4)!*4!}=4845[/tex]
2.
for probabilty the odds of an outcome is just: number of times the requirement is satisfied/total number of possibliites
we know that there are 4845 possbile groups and only one in which we get all of our friends so it's just
1/4845= .020639%
Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice. The product of Andrew's age and Chris' age is 66. How old is Beatrice?
Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9
