Raquel needs to rent a car while on vacation. The rental company charges $19.95, plus 19 cents for each mile driven. If Raquel only has $40 to spend on the car rental, what is the maximum number of miles she can drive?
__________ miles
Answer:
105
Step-by-step explanation:
$40 - $19.95 = $20.05
$20.05 divided by 0.19 (19¢) = 105.526316
Answer:
105 miles
Step-by-step explanation:
40-19.95= 20.05
20.05/.19= 105.5263157895
round down to 105 miles

h(x)=6/(x-3), find h(5)
h(5) means the value of h(x) at x = 5. So what we have to do is to substitute x = 5 in the function.
We are given the function h(x) below:
[tex] \large{h(x) = \frac{6}{x - 3} }[/tex]
Substitute x = 5 in the equation.
[tex] \large{h(5) = \frac{6}{5 - 3} \longrightarrow \frac{6}{2} }[/tex]
Simplify in the simplest form.
[tex] \large{h(5) = \frac{3}{1} \longrightarrow 3}[/tex]
Thus h(5) is 3.
Answer
h(5) = 3Hope this helps! Let me know if you have any doubts.
To rent a car, Cesar must pay $15 a day plus 5 cents for every mile he drives. In dollars, what is his final bill if he rents a car for 3 days and drives a total of 50 miles?
Answer:
$70
Step-by-step explanation:
What we know:
⇒ He must pay 15 dollars a day
⇒ He needs to pay an additional 5 cent for every mile he drives
⇒ He drives 50 miles for 3 days
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Since he pays $15 a day and he is driving this car for 3 days, we have to multiply 15 by 3.
15*3=45
He drove 50 miles and each mile is 5 cents so we have to multiply those as well.
50*.5=25
Now we add both the sums togather~
25+45= $70
∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞∞The amount he has to spend for his car rental is $275.

Answer:
x = 18
Step-by-step explanation:
so we know that 128* and (6x+20)* have the same value so
128* = (6x+20)*
lets subtract both sides by 20
108* = 6x*
divide both sides by 6:
108/6 = 18
6x/6 = x
18 = x
Have a nice day!

Answer:
It does not make a right triangle
Step-by-step explanation:
To know if these measurements make a right triangle, let's square all values,
15² = 225
20² = 400
24² = 576
Looking at these values, no two values add up that would be equal to one of the values.
Therefore, it does not make a right triangle.

A. 3007 units
B. 12367 units3
C. 9007 units3
D. 1200 units 3
Answer:
A. 300π units³
Step-by-step explanation:
Formula for volume of a cone = ⅓πr²h
Where,
radius (r) = ½(10) = 5 units
height (h) = 36 units
Plug in the values and find the volume in terms of π
Volume of the cone = ⅓*π*5²*36
Volume of the cone = 300π units³

Answers:
First box = 864
Second box = 3136
=================================================
Explanation:
The weird looking E symbol is the greek uppercase letter sigma which stands for "sum". You'll be adding everything in the x^2 column to find that 64+144+256+400 = 864, which is already done for you in the table (as the 864 is at the bottom of the second column, in the "total" row).
In short, you just copy the 864 into the first box.
-------------
For the second box, you'll square the 56 to get 3136
This is because the table shows that adding up all the x values leads to 56
(8+12+16+20 = 56)
So that means [tex]\sum x = 56[/tex] and [tex]\left(\sum x\right)^2 = (56)^2 = 3136[/tex]
The mean height for American adult men is 5 feet 10 inches (5’10"). The standard deviation is roughly 3 inches. Is a 5’7" man considered abnormally short? Discuss your reasons.
Solution :
Given :
The mean height of an American adult = 5 feet 10 inches
Therefore converting feet into inches,
We know, 1 feet = 12 inches
So, 5 feet = 5 x 12 = 60 inches
The mean height in inches = 60+10
= 70 inches
The standard deviation = 3 inches
x = 5 feet 7 inches
= 5 x 12 + 7
= 67 inches
∴ z score = [tex]\frac{x-mean}{sd}[/tex]
[tex]$=\frac{67-70}{3}$[/tex]
[tex]=\frac{-3}{3}[/tex]
[tex]$=-1$[/tex]
Therefore, the man's height is 1 standard deviation below mean
Any score above greater than 3 or less than -3 is considered to be an outliner.
Here its only -1 and it is less than -3.
Therefore, the height of the man 5'7'' is not considered abnormally short.

How many and what type of solutions does 7x^2−4x+3 have? 1 rational solution 2 rational solutions 2 irrational solutions 2 nonreal solutions
Answer:
2 non real solutions.
Step-by-step explanation:
We need to use discriminant,
for ax²+bx+c=0
The discriminat is b²-4ac
If the discriminant is,
→ less than 0, then 0 real solutions
→ equal to 0, then 1 real solutions
→ more than 0, then 2 real solutions
Given that,
7x²−4x+3=0
a=7, b=-4, and c=3
→ (-4)²-4(7)(3)
→ 16-84
→ -68
You can see this is less than 0, then non real solutions. [2 nonreal solutions]
Answer:
Solution given:
7x²-4x+3=0
taking common 7
7(x²+4/7*x+3/7)=0

If the pool is to be 24 ft on each side, what is the length of one side of the hot tub?
Answer:
the side length of the hot tub = 4.8ft
Step-by-step explanation:
Scale Factor = 5
Also,
B'C' = 24 feet
Since both are squares so both have all sides equal.
Square A'B'C'D' is dilated by a scale factor of 5
So,
AB = BC = CD = DA = 24/5 = 4.8 ft.
i hope this helps you
The length of the one side of the hot tub is 4.8 ft.
What is Scale Factor?
The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
Here, Richardo wants to build a square pool of the hot tub using a scale factor of 5.
If the each side of the pool is 24 ft.
The length of one side of hot tub = 24/5 = 4.8 ft.
Thus, the length of the one side of the hot tub is 4.8 ft.

Mrs. Bollo's second grade class of thirty students conducted a pet ownership survey. Results of the survey indicate that 8 students own a cat, 15 students own a dog, and 5 students own both a cat and a dog. How many of the students surveyed own only a cat?
a) 18
b) 15
c) None of these answers
d) 8
Answer:
c) None of these answers
Step-by-step explanation:
8 students own a cat
In this, we count the students who own both a dog and a cat, and the students who own only a cat.
5 students own both a cat and a dog.
So of the 8 who own a cat, 5 own both a cat and a dog, and 8 - 5 = 3 own only a cat.
So the correct answer is given by option c, as 3 is not an option.
Find the largest possible rectangular area you can enclose, assuming you have 128 meters of fencing. What is the (geometric) significance of the dimensions of this largest possible enclosure?
Answer:
Step-by-step explanation:
let the length=x
width=y
P=2(x+y)=128
x+y=128/2=64
y=64-x
area A=xy=x(64-x)=64x-x²
[tex]\frac{dA}{dx} =64-2x\\\\\frac{dA}{dx} =0,gives~64-2x=0,x=32\\\frac{d^2A}{dx^2} =-2<0 ,at ~x=32[/tex]
so A or area is maximum if x=32
y=64-32=32
or it is a square of edge=32 meters.

If the surface area of the box in the diagram is 204.25 square feet, what is the value of ‘x’?

the height is 6.5ft
what would x
A. 3 ft
B. 2.25 ft
C. 4.5 ft
D. 5 ft
Note: Consider x be the breadth of the box.
Given:
The surface area of the box is 204.25 square feet.
Length of the box = 10 ft
Breadth of the box = x ft
Height of the box = 6.5 ft
To find:
The value of x.
Solution:
The surface area of a cuboid is:
[tex]SA=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height of the cuboid.
Putting [tex]SA=204.25, l=10,\ b=x,\ h=6.5[/tex] in the above formula, we get
[tex]204.25=2(10\times x+x\times 6.5+6.5\times 10)[/tex]
[tex]204.25=2(10x+6.5x+65)[/tex]
[tex]204.25=2(16.5x+65)[/tex]
Using distributive property, we get
[tex]204.25=2(16.5x)+2(65)[/tex]
[tex]204.25=33x+130[/tex]
[tex]204.25-130=33x[/tex]
[tex]74.25=33x[/tex]
Divide both sides by 33.
[tex]\dfrac{74.25}{33}=x[/tex]
[tex]2.25=x[/tex]
Therefore, the correct option is B.
