Answer:
Length of the rectangle = 43 inches
Width of the rectangle= 20 inches
Step-by-step explanation:
Let the width (w) of the rectangle be = x inches-> Length (l) of the rectangle will be = (2x + 3) inches.Perimeter of the rectangle = 126 inches-> 2(l + w) = 126-> l + w = 126/2-> l + w = 63 -> x + (2x + 3) = 63-> 3x = 63 - 3-> 3x = 60-> x = 60/3-> x = 20 -> 2x + 3 = 2(20) + 3 = 43 Thus, Length of the rectangle = 43 inchesWidth of the rectangle= 20 inchesI’ll give points + brainalist!!

They wrote the model `n=40\cdot1.5^{t}` , where `n` is the total number of squirrels and `t` is the number of years since the biologists started counting. How many squirrels do the biologists predict there will be `2` years after they started counting
The number of squirrels that the biologists predict there will be 2 years after they started counting will be 43 squirrels.
How to illustrate the information?It should be noted that a function is used to show the relationship between the variables.
It should be noted that the function that's given is illustrated as:
n = 40 + 1.5t
In this case, it should be noted that t = 2 years.
Therefore, the number of squirrels that the biologists predict there will be 3 years after they started counting will be:
n = 40 + 1.5t
n = 40 + 1.5(2)
n = 40 + 4
n = 43

I started golfing again recently and I've played 5 rounds of golf with the following scores: 92, 88, 85, 90, and 89. What score would I need the next time I play to have an average below 88.
The next score should by less than 84 to have an average below 88.
What is an average?The term average is the sum of all the numbers divided by the total number of values in the set.
Mathematically,
Average = Sum of the observations/number of observations
Now given that,
Scores = 92, 88, 85, 90, and 89
Rounds = 5
Let x be the score the score for next round or sixth round.
So, According to question,
Average < 88
So, Average = Sum of the scores/number of rounds
⇒ Average = (92 + 88 + 85 + 90 + 89 + x)/6
⇒ Average = (444 + x)/6
⇒ (444 + x)/6 < 88
⇒ (444 + x) < 528
⇒ x < 528 - 444
⇒ x < 84
Thus, the next score should by less than 84 to have an average below 88.

7. There are 7 pairs of green socks, 6 pairs of white socks, 5 pairs of red socks and 4 pairs of blue socks. One person is asked to close his eyes, and draw the socks 1 pair at a time. At least how many pairs of socks should be drawn so that among the drawn socks, 4 pairs of those have the same color?
Answer:
13
Step-by-step explanation:
We can think of this as drawing 3 pairs of each color, and then the next pair will guarantee we have 4 of one color.
This is 3(4)+1=13 pairs.
Step-by-step explanation:
let me see, if I understand this right.
7 pairs of green socks = 14 green socks.
6 pairs of white socks = 12 white socks.
5 pairs of red socks = 10 red socks.
4 pairs of blue socks = 8 blue socks.
in total : 44 socks (or 22 pairs).
the person is pulling socks always 2 at a time. but each sock can be any color.
or are the pairs still connected, and each draw pulls a pair of equal socks ?
and then the question also really is, what is meant by 4 pairs have the same color ? that i find 4 groups of 2 socks each with the save color inside the group (making them pairs), or truly 4 pairs with the same color (e.g. 4 red pairs, or 4 green pairs) ?
if the pairs are still connected, only the second question makes sense.
the worst that can happen in that scenario is drawing
3 pairs of blue socks.
3 pairs of red socks.
3 pairs of white socks.
3 pairs of green socks.
this now like in Baseball : the bases are loaded. any additional runner will cause a score.
because any additional draw must complete one of the groups of 4 pairs.
so, latest after the 4×3 = 12 draws, we get a 13th draw. that gives us 4 equally colored pairs of socks for sure.
so, we need 13 draws.
if each sock is in there individually, and we still want to have 4 pairs of socks all with the same color, then it starts similarly :
the socks get pulled 2 by 2 but that means each drawn pair can have different colors of the individual socks.
in the worst case after drawing 24 socks (12 groups of 2 socks), we have the same situation as in the previous case.
but now, pulling 2 more socks does not guarantee a full set of 4 pairs. we could get 2 different socks that add only half a pair to 2 color groups.
the same with the next pulled group of 2. they fill up the other 2 color groups with half-pairs.
but now the base are loaded. by pulling the next (3rd) additional group of 4, we complete at least one color group with 4 full pairs.
so, we need 12 + 3 = 15 draws to make absolutely sure.
now, if we have individual socks, and want to get 4 pairs of socks that have just the same color inside their pair, we need to think a little bit differently.
after 2 draws (4 socks) we have in the worst case 4 individual socks with different colors.
after the next 2 draws we can be already lucky, but in the worst case we are not but have now either 2.5 full pairs of one color and 3 individual socks, or 2 full pairs in one color, 1 full pair in a second color, and 2 individual socks, or 1.5 pairs in one color, 2×1 full pairs in 2 other colors, and 1 individual sock.
with the next draw in the worst case we could only extend the second case and get 2.5 pairs in one color, 1.5 pairs in the second color and still 2 individual socks.
but now the bases are loaded, and the next draw of 2 socks guarantees that we have 4 real pairs of socks (either 3 and 1 and still 2 individual socks, or 3 and 2 pairs and 2 individual socks, or 2 and 2×1 and wherever the second sock goes, it does not matter, or any other combination where at least one of the individual socks have been combined to a pair.
so, we need
2+2+1+1 = 6 draws.
h is a trigonometric function of the form h(x) = a sin(bx + c) + d.
Below is the graph h(x). The function intersects its midline at (-4pi,2.5) and has a maximum
point at(-5pi/2,6)
Find a formula for h(x). Give an exact expression.
The expression acquired is h(x) = 3.5 sin(1/3x ₊ 4π/3)₊2.5
Given h(x) = a sin(bx ₊ c) ₊ d
The h(x) function intersects its mid line at (₋4π , 2.5)
and has its maximum points at (₋5π/2 , 6)
therefore, x₂ ₋ x₁ = ₋5π/2 ₋ (₋4π)
= ₋5π/2 ₊ 4π
= 3π/2
⇒ 2π/b = 3π/2 4
⇒ 2π/b = 6π
⇒b = 1/3
hence, a = b ₋ 2.5
a = 3.5
now h(x) = 3.5 sin(1/3x ₊ c) ₊ 2.5
x = ₋4π
h(₋4π) = 3.5 sin( ₋4π/3 ₊ c) ₊ 2.5
₋4π/3 ₊ c = 0
c = 4π/3
therefore, h(x) = 3.5 sin(1/3x ₊ 4π/3)₊2.5
hence after solving the equation we get the expression for h(x) as
h(x) = 3.5 sin(1/3x ₊ 4π/3)₊2.5

Bill's school is selling tickets to a fall musical.
On the first day of ticket sales the school sold 1 adult ticket
and 6 child tickets for a total of $52.
The school took in $66 on the second day by selling 1 adult
ticket and 8 child tickets.
Find the price of an adult ticket.
•$3
•$10
•$7
•$9
By solving a system of equations, we can see that the adult ticket costs $10.
How to find the price of the adult ticket?
Let's define the two variables:
x = price of the adult ticket.y = price of the child ticket.With the given information, we can write a system of equations:
1*x + 6*y = $52
1*x + 8*y = $66
By taking the difference between the two equations we get:
(1*x + 8*y) - (1*x + 6*y) = $66 - $52
2y = $14
y = $14/2 = $7
Now that we know the value of y, we can find the value of x.
Replacing the value of y in the first equation we get:
1*x + 6*$7 = $52
x = $52 - 6*$7 = $10
With this, we know that the adult ticket costs $10.

The length of a rectangular garden is 10 feet longer than its width. The garden's perimeter is 188 feet. Find the width of the garden.
Answer: width of the garden is 42
Step-by-step explanation:
let's say "x" = the garden's length
and "y" = the garden's width
the length of the garden is 10 feet longer than its width
x-10=y
the garden's perimeter is 188 feet
we can set up a new equation like this:
2x+2y=188
now we have two equations and we can solve using the system of equations.
x-10=y
add 10 on both sides to isolate "x"
x=y+10
2x+2y=188
substitue x for y+10 in the second equation
2(y+10)+2y=188
expand
2y+20+2y=188
combine like terms
4y+20=188
subtract 20 from both sides
4y=168
divide by four on both sides
y=42
the width of the garden is 42 feet

Landon was making snacks for his family for the week. He used 25/35 of a pound of peanuts. Additionally he use 1/7 of a pound of almonds. At the end of the week, he determined that 3/5 of the snacks were leftover. At the end of the week, how much snacks, in pounds, was used?
Landon used an amount of 4 / 7 of a pound of snacks for his family of the week.
How to estimate the amount of snacks spent per week
In this problem we must determine the total amount of snacks used by Landon in a period of a week, which is found by the summing fractions. Then, we must solve the following linear equation:
(3 / 5) · x = x - 25 / 35 - 1 / 7
(3 / 5) · x = x - 25 / 35 - 5 / 35
(3 / 5) · x = x - 20 / 35
x - (3 / 5) · x = 20 / 35
(2 / 5) · x = 20 / 35
7 · x = 10
x = 10 / 7
And the amount of snack used is determined by the following subtraction:
z = (2 / 5) · (10 / 7)
z = 20 /35
z = 4 / 7

What is the distance between (4, 2) and (8, 5)
The distance between (4, 2) and (8, 5) is 5 units.
The distance between two given points can be calculated using the following formula :
Distance, D = [ ( x2 - x1 )^2 + ( y2 - y1 )^2 ]^1/2
Coordinates of point A = (4,2)
Coordinates of point B = (8,5)
For the above mentioned formula, we get
x1 = 4
x2 = 8
y1 = 2
y2 = 5
Substituting these values in the distance formula, we get
D = [ ( 8 - 4 )^2 + ( 5 - 2 )^2 ]^1/2
=> D = [ ( 4 )^2 + ( 3 )^2 ]^1/2
=> D = [ 16 + 9 ]^1/2
=> D = [25]^1/2
=> D = 5
Therefore, using the distance formula, we get the distance between (4, 2) and (8, 5) as 5 units.
