The Science Club went on a two-day field trip. The first day the members paid $50 for transportation plus
$18 per ticket to the planetarium. The second day they paid $95 for transportation plus $15 per ticket to
the geology museum. Write an expression to represent the total cost for two days for the n members of
the club.
An expression that represents the total cost in dollars for two days for the n members of the club is given
by
HARD! [Ma
Answer:
145 + 33n
Step-by-step explanation:
Let
n = number of members in the club
Day 1:
Cost = 50 + 18n
Day 2:
Cost = 95 + 15n
Total cost two-day field trip = day 1 + day 2
= (50 + 18n) + (95 + 15n)
= 50 + 18n + 95 + 15n
= 145 + 33n
Total cost two-day field trip = 145 + 33n
An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n

Angle 1 and Angle 2 are supplementary. Which equation could you use to find the measure of Angle 2?
Angle 1: 67°
Angle 2: x degrees
Answer: 67 + x = 180
Step-by-step explanation:
Since the angles are supplementary, together they'd add up to 180. Since we do not know the degrees of Angle 2, we arrange x in the equation.
Hope this helps you! Good luck! <3
An item is regularly priced at $31 . It is on sale for 65% off the regular price.
65% off means the sale price would be 35% of the original price ( 100% - 65% = 35%)
To find the sale price multiply the original price by 35%
31 x 0.35 = 10.85
The sale price is $10.85
Solve for the value of e.
please help
Answer:
44
Step-by-step explanation:
Angles that form a straight line add up to equal 180 degrees
Hence, e + 8 + 3e - 4 = 180
^ ( note that we just created an equation that we can use to
solve for e )
Using the equation created, we then solve for e
e + 8 + 3e - 4 = 180
step 1 combine like terms
3e + e = 4e
8 - 4 = 4
we now have 180 = 4e + 4
step 2 subtract 4 from each side
180 - 4 = 176
4 - 4 cancels out
we now have 176 = 4e
step 3 divide each side by 4
176 / 4 = 44
4e / 4 = e
we're left with e = 44

Earth has a diameter of approximately 8,000 miles. If the circumference of a circle can be found using the formula C = πd, what is the circumference of Earth? (Use 3.14 for π)
Answer: Circumference of Earth= 25120 miles
Step-by-step explanation:
Given: The circumference of a circle can be found using the formula [tex]C = \pi d[/tex], where d= diameter of the circle.
Earth's diameter = 8000 miles (approx)
The circumference of circle = [tex]3.14\times 8000[/tex] [substitute values in formula]
The circumference of circle = 25120 miles (approx)
Hence, the circumference of Earth= 25120 miles (approx)

Step-by-step explanation:
Question-4:from the graph we acquire that
length:4width:3.5remember that,
[tex] \displaystyle A _{ \text{rect}} = l \times w[/tex]
thus substitute:
[tex] \displaystyle A _{ \text{rect}} = 4 \times 3.5 \: [/tex]
simplify multiplication:
[tex] \displaystyle A _{ \text{rect}} = 14\: [/tex]
14 means that the rectangle has 14 squares
so,
[tex] \displaystyle 1 \: \text{square} \implies 4 \: { \text{yards}}^{2} \\ 14 \: \text{square} \implies 14 \times 4 \: { \text{yards}}^{2} \\ \qquad = 56 \: { \text{yards}}^{2} [/tex]
Question-5:likewise
from the graph we acquire that
length:6 wide:3.5likewise
[tex] \displaystyle A _{ \text{rect}} = 6 \times 3.5 \: [/tex]
simplify multiplication:
[tex] \displaystyle A _{ \text{rect}} = 21[/tex]
so,
[tex] \displaystyle 1 \: \text{square} \implies 16 \: { \text{yards}}^{2} \\ 21 \: \text{square} \implies 16 \times 21 \: { \text{yards}}^{2} \\ \qquad = 336\: { \text{yards}}^{2} [/tex]

Create a polynomial function in factored form that crosses through the x-axis at -2 and touches the x-axis and turns around at 4.
Given:
A polynomial crosses through the x-axis at -2 and touches the x-axis and turns around at 4.
To find:
The polynomial function in factored form.
Solution:
If the graph of a polynomial intersect the x-axis at [tex]x=a[/tex], then [tex](x-a)[/tex] is a factor of the polynomial.
If the graph of a polynomial touches the x-axis at [tex]x=b[/tex], then [tex](x-b)[/tex] is a factor of the polynomial with multiplicity 2. In other words [tex](x-b)^2[/tex] is the factor of the polynomial.
It is given that the polynomial crosses through the x-axis at -2. So, [tex](x+2)[/tex] is a factor of required polynomial.
It is given that the polynomial touches the x-axis and turns around at 4. So, [tex](x-4)^2[/tex] is a factor of required polynomial.
Now, the required polynomial is:
[tex]P(x)=(x+2)(x-4)^2[/tex]
Therefore, the required polynomial is [tex]P(x)=(x+2)(x-4)^2[/tex].

The question is incorrect. Please see the correct question
Jill, an employee at Old Navy, budgets 1/3 of her yearly salary for clothing. Jill's total clothing bill for the year is $8,220. What is her yearly salary
Answer:
24,660
Step-by-step explanation:
Let y represent her yearly salary
1/3 × y
1/3y
1/3y= 8220
Cross multiply
y= 8220 ×3
= 24,660
Hence Jill yearly salary is 24,660

What is 6 fewer than 3 times a number
Answer:
3x - 6
Step-by-step explanation:
Using the keywords "a number" and "few than" and "times" we can identify the expression.
Answer:
Let the number be x
Basically, 3 times a number is 3x and 6 fewer than 3 times a number is 3x-6 (that is, 6 is less than 3x)
Hence the required expression is 3x-6.

Answer:
5
Step-by-step explanation:
Both angles together will equal as they are opposite of each other
therefore
15x=16x-5
15x+5=16x
5=x
Answer:
x = 5
Step-by-step explanation:
The two angles are congruent because of the Vertical Angles Theorem. Since we now know that they're congruent, we can set up an equation to like this:
15x = 16x - 5
Now that we have an equation, we can solve for x.
First, we subtract 15x from both sides. Now we're left with an equation that should look like this:
0 = x - 5
Now we add 5 to both sides to get our solution. It should look like this.
5 = x
And there's your answer! Hope this helps.

Vincent is building a rectangular pen for his new pet rabbit. The area of the pen is 36 square feet. The length of the fence is 5 feet longer than its width. Write the equation that can be used to model the relationship between the area of the gate and side length
Answer:
w² + 5w = 36
Step-by-step explanation:
Since the pen is a rectangle, its area, A = lw where l = length and w = width.
Since the length of the fence is 5 feet longer than its width, we have l = w + 5
So, A = lw = (w + 5)w = w² + 5w
Since A = 36 ft², we have that
36 = w² + 5w
w² + 5w = 36
Which is the required equation.
