Water World charges customers $50 per day to rent a canoe and $25 as a nonrefundable insurance fee.
Which function represents the total cost, y, of renting a canoe for x days at Water World?
Answer:
y=50x+25
The x days would multiply by 50 and adding 25 to 50x to get y.

Help please this is 6th-grade math
Step-by-step explanation:
✰ [tex] \underline {\underline{ \large{ \tt{G \: I \: V \: E \: N : }}}} \: [/tex]
Area of a triangle ( A ) = 49 inches²Let height of the triangle be ' x '. According to question , base of the triangle is twice the height ( i.e 2x ).✰ [tex] \underline{ \underline{ \large{\tt{S \: O \: L \: U\: T \: I \: O\: N : }}}}[/tex]
[tex] \boxed{ \large{ \tt{Area \: of \: a \: triangle = \frac{1}{2} \: b \: \times \: h}}}[/tex]
Plug the values and then simplify!
⟶ [tex] \large{ \tt{49 = \frac{1}{2} \times 2x \times x}}[/tex]
⟶ [tex] \large{ \tt{49 = {x}^{2} }}[/tex]
⟶ [tex] \large{ \tt{ {x}^{2} = 49}}[/tex]
⟶ [tex] \large{ \tt{x = \sqrt{49}}} [/tex]
⟶ [tex] \large{ \tt{x = \sqrt{ {(7)}^{2} } }}[/tex]
⟶ [tex] \boxed{\large{ \tt{x = 7 \: inches}}}[/tex]
Again , Replacing values , we get :
[tex] \large{ \tt{Base \: ( \: b \: ) = 2x = 2 \times 7 = \boxed{ \large { \tt{14 \: inches}}}}}[/tex]
Therefore ,
The base of the triangle is [tex] \large{ \underline{ \tt{14 \: inches}}}[/tex].The height of triangle is [tex] \underline{ \large{ \tt{7 \: inches}}}[/tex]And we're done ! ✔

Which ordered pair is a solution to the graphed inequality?
Given:
The graph of a system of inequalities.
To find:
The ordered pair which is a solution to the graphed inequality.
Solution:
The boundary lines are:
[tex]x-2y=4[/tex]
[tex]2x-y=4[/tex]
From the given graph it is clear that only point (3,1) lies in the shaded region.
Points (2,-1) and (4,0) lie on the boundary line [tex]x-2y=4[/tex] but the boundary line is dotted. It means the points on the line are not in the solution set.
point (0,-1) does not belong to the shaded region.
Therefore, the correct option is A.

how many years to double investment if interest rate is .10%
Answer:
How the Rule of 72 Works. For example, the Rule of 72 states that $1 invested at an annual fixed interest rate of 10% would take 7.2 years ((72/10) = 7.2) to grow to $2. In reality, a 10% investment will take 7.3 years to double ((1.107.3 = 2). The Rule of 72 is reasonably accurate for low rates of return.
Step-by-step explanation:
For example, if you invest $10,000 at 10 percent compound interest, then the “Rule of 72” states that in 7.2 years you will have $20,000. You divide 72 by 10 percent to get the time it takes for your money to double. The “Rule of 72” is a rule of thumb that gives approximate results

Answer:
The answer is C.
Step-by-step explanation:
825-735 is 90.
830-755 is 75.
90-75 is 15 meaning Drew beat Kurt by 15 minutes.
Answer:
Drew: 15 Minutes Faster
Step-by-step explanation:
All we have to do is subtract 8:25 by 7:35 to figure out the time kurt took to get to school, which would equal to 90 minutes. Then we have to subtract 8:30 by 7:55 to get the amount of time it took for Drew to get to school which is 75 minutes. We can see that Drew has the lowest number which means he got to school faster so last step is to subtract the two times 90-75 which equals to 15. Which means drew got to school 15 minutes faster.

Gwendolyn is asked to solve the equation –4(x – 3) = 20. She shows the work below and states that the solution is x = –8. –4(x – 3) = 20 –4x + 12 = 20 –4x = 32 x = –8 Unfortunately, Gwendolyn's work is flawed. Explain the flaw in Gwendolyn's work. Determine the correct solution to the equation.
Answer:
[tex]x=-2[/tex]
Step-by-step explanation:
Given: Equation is [tex]-4(x-3)=20[/tex]
To find: flaw in Gwendolyn's work and the correct solution to the equation.
Solution:
In the given question,
the first step is [tex]-4(x-3)=20[/tex]
The second step is [tex]-4x+12=20[/tex]
(This step is obtained on multiplying [tex]-4[/tex] by [tex]x-3[/tex])
The third step is [tex]-4x=32[/tex]
This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:
[tex]-4x=20-12\\-4x=8\\x=-2[/tex]
So, the correct solution is [tex]x=-2[/tex]

please help !! Use Pythagorean theorem :) and show your work if you can thanks :”) will give b
Answer:
[tex]b=\sqrt{1575}[/tex] ≈ 39.7ft
Step-by-step explanation:
The Pythagorean theorem:
[tex]a^{2}+ b^{2}= c^{2}[/tex]
(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)
First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.
[tex]45^{2}+ b^{2}= 60^{2}[/tex]
[tex]2025+b^{2} =3600[/tex]
To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:
[tex]b^{2} =1575[/tex]
[tex]b=\sqrt{1575}[/tex] ≈ 39.7ft
Which list shows the sides in order from shortest to longest

The measure of the angle ∠JKL is 230°, the area of the shaded and unshaded region is (230/18) × 5π and (325/9) × π. Then statements 1 and 3 are true and statement 2 is false.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The figure is given.
Radius (r) = 10 units
Then the sum of the angle should be 360 degrees for a circle. Then
130° + ∠JKL = 360°
∠JKL = 230°
The area of the shaded region will be
[tex]\rm Shaded \ area = \dfrac{230}{360}\times \pi 10^2\\\\Shaded \ area = \dfrac{230}{360}\times \pi 100\\\\Shaded \ area = \dfrac{230}{18}\times 5\pi \\[/tex]
Then the area of the unshaded region will be
[tex]\rm Unshaded \ area = \dfrac{130}{360}\times \pi 10^2\\\\Unshaded \ area = \dfrac{130}{360}\times \pi 100\\\\Unshaded \ area = \dfrac{325}{9}\times \pi \\[/tex]
