Answer:
913x - 96Step-by-step explanation:
Given
The expression of number of people entering on Saturdays = 508x-70
The expression of number of people entering on Sundays = 405x-26
total amount of people entering the theme park that weekend = Total entering on Saturday + total entering on Sunday
Substitute the expression;
total amount = 508x - 70 +(405x-26)
total amount = 508x+405x-70-26
total amount = 913x - 96
Hence the total amount of people entering the theme park that weekend is 913x - 96
A population of bees is decreasing. The population in a particular region this year is 1250. After year 1, it is estimated that the population will be 1000. After 2 years it is estimated that the population will be 800. How many years will it take for the bee to be below 100?
Answer:
1250 => 250 ( subtracted from the balance population )
1000 => 300
800 => 350
450. => 400
50.
So it will take around 5 years I think to be below 100.

production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). There are two production methods it could use. With one method, the one-time fixed costs will total $19,593, and the variable costs will be per book. With the other method, the one-time fixed costs will total $63,702, and the variable costs will be $10 per book. For how many books produced will the costs from the two methods be the same?

Your dad is designing a new garden for your backyard. He has 20 feet of fencing to go around the garden. He wants the length of the garden to be 2 1/2 feet longer than the width. How long should he make the garden?
Answer:
Length = 6.25 feet
Step-by-step explanation:
Your dad is designing a new garden for your backyard. He has 20 feet of fencing to go around the garden.
Let the width is x.
Length is 2 1/2 feet longer than the width i.e. (x+2 1/2) = (x+2.5) feet
Perimeter = 20 feet
2(l+b) = 20
(l+b) = 10
(x+2.5+x) = 10
2x+2.5 = 10
2x = 7.5
x = 3.75 feet
Length = (x+2.5)
= (3.75+2.5)
= 6.25 feet
So, the length of the garden is 6.25 feet.

Answer:
F. [tex] 4, 4\sqrt{3} [/tex]
Step-by-step explanation:
✔️Finding length of side s using:
[tex] cos(\theta) = \frac{adjacent}{hypotenuse} [/tex]
Where,
[tex] cos(\theta) = cos(60) = \frac{1}{2} [/tex]
Adjacent = s
Hypotenuse = 8
Plug in the values
[tex] \frac{1}{2} = \frac{s}{8} [/tex]
Multiply both sides by 8
[tex] \frac{1}{2} \times 8 = \frac{s}{8} \time 8 [/tex]
[tex] \frac{8}{2} = s [/tex]
[tex] 4 = s [/tex]
s = 4
✔️Finding length of side q using:
[tex] sin(\theta) = \frac{opposite}{hypotenuse} [/tex]
Where,
[tex] sin(\theta) = sin(60) = \frac{\sqrt{3}}{2} [/tex]
Opposite = q
Hypotenuse = 8
Plug in the values
[tex] \frac{\sqrt{3}}{2} = \frac{q}{8} [/tex]
Multiply both sides by 8
[tex] \frac{\sqrt{3}}{2} \times 8 = \frac{q}{8} \times 8 [/tex]
[tex] \frac{\sqrt{3}}{1} \times 4 = q [/tex]
[tex] 4\sqrt{3} = q [/tex]
[tex] q = 4\sqrt{3} [/tex]
A washer and a dryer cost $834 combined. The washer costs $84 more than the dryer. What is the cost of the dryer?
Answer:
The dryer cost $375
Step-by-step explanation:
834/2 = 417
84/2 = 42
417 - 42 = 375
834 - 375 = 459
459 - 84 = 375
PROOF: 417 - 375 = 42 then double that answer to get 84

What value of R makes r/ -11 = (-3) true
Answer:
The value of [tex]r=33[/tex] which makes the equation true.
Step-by-step explanation:
Given the equation
[tex]\frac{r}{-11}=-3[/tex]
We have to find the value of r for which the equation must be true.
solving the equation
[tex]\frac{r}{-11}=-3[/tex]
Multiply both sides by -11
[tex]\frac{r\left(-11\right)}{-11}=\left(-3\right)\left(-11\right)[/tex]
[tex]r=33[/tex]
Therefore, the value of [tex]r=33[/tex] which makes the equation true.
VERIFICATION:
Putting [tex]r=33[/tex] in the equation
[tex]\frac{r}{-11}=-3[/tex]
[tex]\frac{33}{-11}=-3[/tex]
[tex]-3=-3[/tex] ∵ [tex]\frac{33}{-11}=-3[/tex]
L.H.S = R.H.S
Therefore, the value of [tex]r=33[/tex] which makes the equation true.
Alberto is painting a square canvas. What is the length of each side?
Which equation is equivalent to y = -9/4(x - 8) + 6 when solved for x?
Answer:
X = -4Y/9 + 32/3
Step-by-step explanation:
you can solve for X by simplifying both sides of the equation then isolating the variable
The value of the given equation y = -9/4(x - 8) + 6 for the x will be x = -(4/9)y + 96/9
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given the equation,
y = -9/4(x - 8) + 6
By taking LCM in right-hand side
y = [-9(x - 8) + 24]/4
Cross multiply
4y = -9(x - 8) + 24
Interchange
9(x - 8) = 24 - 4y
9x - 72 = 24 - 4y
x = (4/9)y + 96/9
Hence "The value of the given equation y = -9/4(x - 8) + 6 for the x will be x = -(4/9)y + 96/9".

A sequence is shown below. 4, 8, 16, 32, . . . Which formula can be used to determine the nth term in the sequence? Use the formula to find a8.
Answer:
a8 = 512.
Step-by-step explanation:
This is geometric sequence with common ratio r = 2 and first term a1 = 4.
nth term = a1 r^(n-1)
So a8 = 4 2(^8-1)
= 4 * 2^7
= 4*128 = 512.
Kiran walked at a constant speed. He walked 1 mile in 15 minutes. Which of these equations represents the distance d (in miles) that Kiran walks in t minutes?
Answer: [tex]d=\dfrac{t}{15}[/tex], where d= distance that Kiran walks in t minutes.
Step-by-step explanation:
Given: Kiran walked at a constant speed.
He walked 1 mile in 15 minutes.
The, distance walked by Kiran in 1 minute = [tex]\dfrac1{15}[/tex] mile
The distance that Kiran walks in t minutes = [tex]t\times\dfrac{1}{15}[/tex] miles
If d= distance that Kiran walks in t minutes
The required equation: [tex]d=\dfrac{t}{15}[/tex]

Step-by-step explanation:
Step one:
given data
let the shirts be x
and the pants be y
Required
the number of shirts and pants
the systems of the equation for the situation is
2x+6y=11-------------1
5x+8y=18.75-------2
2x+6y=11-------------1X 5
5x+8y=18.75-------2 X2
10x+30y=55-------------1
-10x+16y=37.5-------2
0x+14y=-17.5
divide both sides by 14
y=17.5/14
y=1.25
pants= $1.25
put y=2.32 in eqn 1 2x+6y=11
2x+6(1.25)=11
2x+7.5=11
2x=11-7.5
2x=3.5
x=3.5/2
x=$1.75

A side of the triangle below has been extended to form an exterior angle of 125°. Find the value of X
Answer:
x = 19°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 106° = 125° ( subtract 106° from both sides )
x = 19°
Accessories Central is having a summer clearance on sunglasses. Maria wants to buy a pair of sunglasses that cost $48 with a 65% discount. The same pair of sunglasses costs $38 with a 55% discount at Shades, Inc. What is the price difference between Accessories Central and Shades, Inc?
Answer:
Step-by-step explanation:
First, find the cost of both pairs of sunglasses after the discounts
65% = 65/100 = 0.65
($48)(0.65) = $31.20
55% = 55/100 = 0.55
($38)(0.55) = $20.90
Then subtract the bigger cost (31.20) from the smaller cost (20.90)
$31.20 - $20.90 = $10.30
$10.30 is your price difference.

Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle. If the sum of their ages is 77, how old is Gina?
Answer:
Answer : Gina's age is 19 years.
Step-by-step explanation:
Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle.
Let Gina's age be x years
So Kamal’s age will be = x + 17
Rachelle’s age = x + 3
the sum of their ages is 77, Accordingly
x + x + 17 + x + 3 = 77
3x + 20 = 77
3x = 77 - 20
3x = 57
x = 57/3
x = 19
Thus Gina's age is 19 years,
Kamal’s age x + 17 = 19 + 17 = 36 years
Rachelle’s age x + 3 = 19 + 3 = 22 years
Gina = 19 years old
The sand pit for the long jump has a width of 2.7 meters and a length of 9.54 meters. Just in case it rains, the principal wants to cover the sand pit with a piece of plastic the night before the event. How many square meters of plastic will the principal need to cover the sand pit?
Answer:
A = 25.758 m²
Step-by-step explanation:
Width of the sand pit, b = 2.7 m
Length of the sand pit, l = 9.54 m
We want to cover the sand pit with a piece of plastic. We need to find how many square meters of plastic will be needed to cover the sand pit. It is equal to the area of sand pit. It is in the shape of rectangle. Its area is given by :
A = l × b
A = 2.7 × 9.54
A = 25.758 m²
So, 25.758 m² of plastic will be needed to cover the sand pit.
