Joshua is going kayaking with a group during one of his vacation days. In his vacation planning, he budgeted $50 for a kayak rental. How can Joshua determine the number of hours he can rent a kayak for himself?
Answer: Divide Kayak budget by rental rate
Step-by-step Explanation:
As Joshua is renting for himself alone, the two available options would be the Single Kayak and the Single Sea Kayak.
He can determine the number of hours to rent a Kayak for by dividing his Kayak Budget by the rental rate per hour of the 2 options available to him.
Single KayakBudget available = $50
Rental rate = $15 per hour
Hours he can rent = 50/15
= 3.33 hours
Single Sea KayakBudget available = $50
Rental rate = $18 per hour
Hours he can rent = 50/18
= 2.78 hours

CAN SOMEONE PLEASE HELP ME ASAP PLEASEEEE!!!
Answer:
11.4
Step-by-step explanation:
So we know that Triangle ACB is similar to Triangle EFD.
This means that their sides are proportional to each other.
We want to find x or side AB. To do so, we can set up a proportion.
The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:
[tex]\frac{AB}{ED}=\frac{BC}{DF}[/tex]
Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:
[tex]\frac{x}{3.8}=\frac{15}{5}[/tex]
Reduce the right:
[tex]\frac{x}{3.8}=\frac{3}{1}[/tex]
Cross multiply:
[tex]x=11.4[/tex]
So, the value of x is 11.4
And we're done!

If g(x) = x^2 – 2x – 6 and h(x) = 2x^2 – 5x + 2 find (h – 9) (-2)
Answer: (h-g)(-2)=18
Step-by-step explanation:
(h – g) (-2) means the same as subtracting h(-2) and g(-2). Since we are given h(x) and g(x), we can use them to solve. There are two ways to solve. One is to find h(-2) and g(-2), and then subtract them. Another way is to do (h-g)(x), then plug in x=-2. I will show both methods.
Method 1
h(-2)=2(-2)²-5(-2)+2 [exponent]
h(-2)=2(4)-5(-2)+2 [multiply]
h(-2)=8+10+2 [add]
h(-2)=20
g(-2)=(-2)²-2(-2)-6 [exponent]
g(-2)=4-2(-2)-6 [multiply]
g(-2)=4+4-6 [add then subtract]
g(-2)=2
(h-g)(-2)=20-2 [subtract h(-2) and g(-2)]
(h-g)(-2)=18
--------------------------------------------------------------------------------------------------------
Method 2
(h-g)(x)=2x²-5x+2-(x²-2x-6) [distribute -1]
(h-g)(x)=2x²-5x+2-x²+2x+6 [combine like terms]
(h-g)(x)=x²-3x+8
(h-g)(-2)=(-2)²-3(-2)+8 [plug in x=-2, exponent]
(h-g)(-2)=4-3(-2)+8 [multiply]
(h-g)(-2)=4+6+8 [add]
(h-g)(-2)=18
--------------------------------------------------------------------------------------------------------
Now, we know that (h-g)(-2)=18. We confirmed this with both methods.

What the square root of 50/ 250 (rounded to 2 decimal places)? * 0.45 0.44 0.47 0.46
Answer:
[tex]Root = 0.44[/tex]
Step-by-step explanation:
Required
Determine the square root of [tex]\frac{50}{250}[/tex]
Start by simplifying the fraction
[tex]Digit = \frac{50}{250}[/tex]
Divide the numerator and denominator by 50
[tex]Digit = \frac{1}{5}[/tex]
Next, determine the square root;
[tex]Root = \sqrt{\frac{1}{5}}[/tex]
Split the squarer root
[tex]Root = \frac{\sqrt{1}}{\sqrt{5}}[/tex]
[tex]Root = \frac{1}{\sqrt{5}}[/tex]
Rationalize
[tex]Root = \frac{1}{\sqrt{5}} * \frac{\sqrt{5}}{\sqrt{5}}[/tex]
[tex]Root = \frac{\sqrt{5}}{5}[/tex]
[tex]Root = \frac{2.2360679775}{5}[/tex]
[tex]Root = 0.4472135955[/tex]
[tex]Root = 0.44[/tex] --- Approximated

What is 75% of 35 feet?
Answer:
26.25 feet
Step-by-step explanation:
A percentage is simply a ratio of the whole. If we assume 35 feet to be 100%, or the whole, then we can say the following:
0.75 * 35 == 26.25
Hence, 75% of 35 feet is 26.25 feet.

Two angles are supplementary if their sum is 180 degrees. The larger angle is 6 degrees more than five times the measure of the smaller angle. Let
x
represent the measure of the smaller angle and these two angles are supplementary, find the measure of each angle.
Answer:
Step-by-step explanation:
x+y=180
y=5*x+6
so
x+5x+6=180
6x=180-6
6x=174
x=174/6
x=29 degrees
y=29*5+6
y=145+6=151
y=151 degrees

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line.
y = 5√49 − x2
y = 0
x = 2
x = 4
Answer:
V = 4316.75 π
Step-by-step explanation:
Given that:
[tex]y = 5 \sqrt{49 -x^2}[/tex] y = 0, x = 2, x = 4
[tex]V = \pi \int \limits ^{x=4}_{x=2} y^2 \ dx[/tex]
where;
y² = 25 (49 - x²)
[tex]V = 25 \pi \int \limits ^4_2 (49-x^2) dx[/tex]
[tex]V = 25 \pi [ (49x-\dfrac{x^3}{3}]^4_2[/tex]
[tex]V = 25 \pi [ 49\times 4 -\dfrac{4^3}{3} - 2][/tex]
[tex]V = 25 \pi [ 196-21.33 - 2][/tex]
[tex]V = 25 \pi [ 172.67][/tex]
V = 4316.75 π

Give the next three terms in each Arithmetic Sequence and the common difference
Answer:
A) Sequence: -5, -10, -15, -20, -25, -30, -35, -40 cd = -5
B) Sequence: -1, 2, 5, 8, 11, 14, 17, 20 cd = 3
C) Sequence: 17, 19, 21, 23, 25, 27, 29, 31 cd = 2
D) Sequence: 11, 16, 21, 26, 31 , 36, 41, 46 cd = 5
E) Sequence: -9, -6, -3, 0, 3, 6, 9, 12 cd = 3
Step-by-step explanation:
A) Sequence: -5, -10, -15, -20, -25
The common difference (cd) - which is the number that we need to add to each term in order to get the next - is -5
and the next three terms are: -30, -35, -40.
B) Sequence: -1, 2, 5, 8, 11,
The common difference is 3, cd = 3
so the next three terms in the sequence are; 14, 17, 20
C) Sequence: 17, 19, 21, 23, 25,
the common difference is 2, cd = 2
so the next three terms in the sequence are: 27, 29, 31
D) Sequence: 11, 16, 21, 26, 31
the common difference is 5, cd = 5
so the next three terms of the sequence are: 36, 41, 46
E) Sequence: -9, -6, -3, 0, 3,
the common difference is 3, cd = 3
so the next three terms in the sequence are: 6, 9, 12

two consecutive integers who sum of 111
Answer:
55 and 56
Step-by-step explanation:
Let the first number = k
the second number = k + 1
k + k + 1 = 111
2k + 1 = 111
2k = 111 - 1
2k = 110
k = 110/2
k = 55
The two numbers are 55 and 56

Tell which set or sets the number below belongs to: natural numbers, whole numbers, integers, rational numbers, irrational numbers, or real numbers. 8/9
Answer:
Rational numbersStep-by-step explanation:
A rational number is a number that can be written as a ratio of two integers. The are expressed as fractions. Given the value 8/9, this value is a fraction and is written as a ratio of two integers 8 and 9.
The value is neither a real number, nor an integer because integers and whole numbers are not expressed as fractions.
Natural numbers are also whole numbers starting from 1 and above. Hence 8/9 is not a natural number as well.
Note that irrational numbers are also classified as real numbers and they can not be written as a ratio of two integers.
Conclusively, 8/9 is only classified as a rational number

Use the simple interest formula to determine the missing value. p =$1325, r =?t=2 years I=$37.10 r=?% (Do not round until the final answer. Then round to one decimal place as needed.)
Answer:
r = 1.4 %
Step-by-step explanation:
given p(principle) is 1,375$, r(interest rate) is unknown, t(time in years) is 2, and I(Interest / final balance) is 37.10$. The simple interest formula: I = prt can be rewritten as: r = I/pt to solve for r. 37.1 / ( 1325 × 2 ) = 37.1 / 2650 = 0.014 = ( 0.014 * 100 ) % = 1.4 %
