Answer:
A. 9,006
Step-by-step explanation:
First we need to find 25% of 4,000
4,000/4 = 1000
So we know there are 1,000 mosquitoes a month.
So In 4 months it would be 4,000 more mosquitoes.
That would be 8,000 but i don't see that so I would say A.
Let me know if I'm correct.

Answer:
8π cm^2
Step-by-step explanation:
Here's your solution
=> Area of biggest circle = πr^2
=> Area = 16π cm^2
=> Area of small circle = 4π cm^2
=> there are two circles hence both area =
8π cm^2
=> now, Area of shaded region = 16π cm^2 - 8π cm^
=> Area = 8π cm^2

If I roll a dice 120 times how many times I expect to get a 2
Answer:
If one rolls a dice 120 times, he/she expect to get a 2, 20 time
Step-by-step explanation:
The probability of getting a 2 when the dice is rolled 1 time is [tex]\frac{1}{6}[/tex]
Given - The dice is rolled for 120 times
Probability of getting a 2 is
[tex]\frac{1}{6} *120\\= 20[/tex]
Thus, if one rolls a dice 120 times, he/she expect to get a 2, 20 time

Carrie will spin the arrow on the spinner four times. What is the probability that the arrow will stop on A, then B, then C, Then D?
Answer:
1 / 256
Step-by-step explanation:
Sample space Total sections of spinner = (A, B, C, D) = 4
P(spinner stops on A) = 1 /4
Second spin :
P(stops on B) = 1/4
Third spin :
P(stops on C) = 1/4
Fourth spin :
P(stops on D) = 1/4
Hence,
P(A then B then C then D)
1/4 * 1/4 * 1/4 * 1/4 = 1
At a computer store, a tablet computer was on sale for 10% off. If the original price of the tablet
was P, what is the sale price in terms of P?
P-10
P-0.10
0.90P
0.10P
Answer:
the discounted price by 10% is P(x) = 0.9x. the price minus a $150 coupon is C(x) = x - 150. so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!
The sale price of a tablet computer is option (C) 0.90P is the correct answer.
What is sale price?Sale price is the price that a customer pays to purchase a product or a commodity. It is a price above the cost price and includes a percentage of profit also. The price after the original price has been reduced by a discount.
For the given situation,
The discount of a tablet computer = 10% = 0.10
The original price of the tablet = P
Sale price = original price - original price(discount)
⇒ [tex]P-P(0.10)[/tex]
⇒ [tex]P(1-0.10)[/tex]
⇒ [tex]P(0.90)[/tex]
Hence we can conclude that the sale price of a tablet computer is option (C) 0.90P is the correct answer.

b = [?]
Answer:
b = 6
Step-by-step explanation:
here's your solution
=> 7/21 = b/18
=> by cross multiplication
=> 21b = 7*18
=> b = 126/21
=> b = 6
hope it helps
Answer:
b = 6
Step-by-step explanation:
To find the answer, find the GCF of 7 and 21, which is 7, and divide it by 7/7 to get 1/3, now the equation is 1/3 = b/18. How many times does 3 multiply to get 18? 6, multiply the first side of the equation by 6/6 to get 6/18, now we have 6/18 = b/18, since they are the same, b = 6

The measure of angle L from the given triangle KLM is 57°.
What is sine rule?Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The formula for sine rule is sinA/a=sinB/b=sinC/c. Where, A=angle A, a=length of side a, B=angle B, b=length of side b, C=angle C and c=length side c.
Given that, in ΔKLM, l = 570 cm, k = 490 cm and ∠K=46°.
By using sine rule in the triangle KLM, we get
sinL/l=sinK/k
sinL/570=sin46°/490
Here, sin46°=0.7193
sinL/570=0.7193/490
sinL/570=0.001467
sinL=0.8367
∠L=sin⁻¹(0.8367)
∠L=57°
Therefore, by using sine rule the measure of angle L is 57°.

Answer:
The answer is J.
Step-by-step explanation:
To find the slope of the line, pick two dots on that are EXACTLY on the grid.
I picked (0,3) and (2,2)
First, count how many units down the two points are from each other
I counted one.
Then, count how many units they are away from the side.
I got 2.
Slopes are rise over run or y over c so the slope is 1/2
The line is negative, too as it is going down so the slope is negative.
Therefore, the slope is -1/2 and only one option have a slope of -1/2 and it’s J
Also, to know which number is the slope look for the number before the x. In slope intercept form, that is the slope.

The area of a rectangular garden is 96 square feet. The width is 4 feet less than the length. What is the length of the garden?
9514 1404 393
Answer:
12 ft
Step-by-step explanation:
We can let x represent the average of length and width. Then the length is x+2, and the width is x-2. Then the area is ...
(x +2)(x -2) = 96
x^2 = 100
x = √100 = 10
The length is x+2, so ...
the length of the garden is 12 feet.
On a coordinate plane, parallelograms A B C D and E F G H are shown. Parallelogram A B C D has points (4, 2), (7, 2), (4, 6), (1, 6). Parallelogram E F G H has points (negative 2, 2), (negative 5, 2), (negative 6, 6), and (negative 3, 6). How do the areas of the parallelograms compare? The area of parallelogram ABCD is 4 square units greater than the area of parallelogram EFGH. The area of parallelogram ABCD is 2 square units greater than the area of parallelogram EFGH. The area of parallelogram ABCD is equal to the area of parallelogram EFGH. The area of parallelogram ABCD is 2 square units less than the area of parallelogram EFGH.
Answer:
The area of parallelogram ABCD is equal to the area of parallelogram EFGH.
Step-by-step explanation:
Given
Parallelogram ABCD
[tex]A = (4,2)[/tex]
[tex]B = (7,2)[/tex]
[tex]C =(4,6)[/tex]
[tex]D = (1,6)[/tex]
Parallelogram EFGH
[tex]E =(-2,2)[/tex]
[tex]F = (-5,2)[/tex]
[tex]G = (-6,6)[/tex]
[tex]H = (-3,6)[/tex]
Required
Compare the areas of both parallelograms
The area of a parallelogram is:
[tex]Area =Base * Height[/tex]
So: To do this, we plot ABCD and EFGH on a grid, then we measure the base and the height of both.
See attachment 1 for ABCD
In (1), we have:
[tex]Base = 3\ units[/tex]
[tex]Height = 4\ units[/tex]
So, the area is:
[tex]A_1 = 3 * 4[/tex]
[tex]A_1 = 12[/tex]
See attachment 2 for EFGH
In (2), we have:
[tex]Base = 3\ units[/tex]
[tex]Height = 4\ units[/tex]
So, the area is:
[tex]A_2 = 3 * 4[/tex]
[tex]A_2 = 12[/tex]
By comparison, they both have the same areas

Olive is allowed to bring one friend on a trip with her.
She does not want to play favorites.
What is NOT a random method of choosing a friend? what’s is NOT a random method of choosing a friend
Answer:
Process of elimination
Step-by-step explanation:
If Olive wants to choose a friend while not playing favorites, while also not being random, she has to eliminate the ones she knows she will NOT take on the trip. She can choose this by selecting the one she knows that will be best on the trip with her, depending on the situation.
Or, if Olive only has one friend, then it wouldn't be surprising that she would take that one friend on the trip, since she has no one else to choose. This way, it is not playing favorites, nor is it random. Hope this helps you!
Mary makes trait mix with bulk nuts and dried fruit. She spends on the dried fruit Mixed nuts cost $2.50 per pound. She has a total of $12 to spend
How many pounds of nuts can she buy?
Answer:
4 pounds
Step by Step Explaintion
The required Mary can buy 4 pounds of mixed nuts with her remaining budget.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
If Mary has a total of $12 to spend and she spends $2.50 on dried fruit, then she has $12 - $2.50 = $9.50 left to spend on mixed nuts.
If mixed nuts cost $2.50 per pound, then Mary can buy $9.50 / $2.50 per pound = 3.8 pounds of mixed nuts.
However, since Mary cannot buy a fraction of a pound, the actual amount of mixed nuts she can buy will be limited to the nearest whole number.
Therefore, Mary can buy 4 pounds of mixed nuts with her remaining budget.
