Marc is planning a holiday for 4 people for 7 days.
Here are the costs for the holiday for each person.
Travel
£250
Hotel
£50 for each day
Spending money £350
Work out the total cost of the holiday for 4 people for 7 days.
Answer:
£3,800
Step-by-step explanation:
The computation of the total cost is shown below;
Each person cost is
Travel cost £250 (assume for 7 days)
Hotel cost £50 × 7 days = £350
Spending money £350 (assume for 7 days)
Cost for each person is £950
Since there are four persons, so the total cost would be
= £950 × 4 peoples
= £3,800

The volume of a golf ball is approximately 4in.3 what is the diameter round you answer to the nearest whole number
A 4 in
B 6 in
C 1 in
D 2 in
Answer:
D. 2 inches.
Step-by-step explanation:
Given the following data;
Volume of golf (sphere) = 4 in³
A golf ball is spherical in shape. Thus, to find its volume we would use the formula for the volume of a sphere.
[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]
Substituting into the equation, we have;
[tex] 4 = \frac {4}{3} * 3.142* r^{3} [/tex]
Cross-multiplying, we have;
[tex] 12 = 4 * 3.142* r^{3} [/tex]
[tex] 12 = 12.568 * r^{3} [/tex]
[tex] r^{3} = \frac {12.568}{12} [/tex]
[tex] r^{3} = 1.0473 [/tex]
Taking the cube root of both sides, we have;
Radius, r = 1.016 inches.
To find the diameter;
Diameter = radius * 2
Diameter = 1.016 * 2
Diameter = 2.03 ≈ 2 inches.
Answer:
the answer is 2.

X+2y=10
X+y=6
Using eliminations to solve each system
Answer:
x= 2
y=4
Just subtract by like numbers.
x + 2y = 10
x + y = 6
Both x's in the equation are equal. We want the x of the last equation to be negative so we can eliminate.
x + 2y = 10
-x - y = -6
Subtract.
y = 4
Now that we figured out y, we have to figure out x. Substitute y into one on the equations.
x + 4 = 6
x = 2
Now we figured out x. The answer is (2,4). I hope this helps! Let me know if I got anything wrong or if you need any more help with this problem.

3. If you buy a new car for $6,000 which depreciates at 4%/year,
what will the value be after 3 years?
Answer:
$5,308.42
Step-by-step explanation:
(see attached for reference)
recall that the formula for Depreciation
is given by
A = P ( 1 - r)^t,
where
A = final amount
P = principal amount = given as $6,000
r = depreciation rate = given as 4% = 0.04
t = time in years = given as 3,
Simply substitute these into the equation to get:
A = P ( 1 - r)^t
= 6000( 1 - 0.04) ^ 3
= 6000 (0.96)^3
= $5,308.42
The answer would be 250

x<-2 is the right answer.Answer:
x < −2
Step-by-step explanation:
Let's solve your inequality step-by-step.
3x + 2 < −4
Step 1: Subtract 2 from both sides.
3x + 2 − 2 < − 4 − 2
3x<−6
Step 2: Divide both sides by 3.
3x / 3 < −6 / 3
x < −2
Answer:
x < −2

PLSSS HELP!! I'LL GIVE BRAINLIEST IF RIGHT Which is the equation of a parabola with a directrix at y = 2 and a focus at (5, 0). A) y = one fourth(x − 5)2 + 1 B) y = one fourth(x + 1)2 − 5 C) y = −one fourth(x + 1)2 − 5 d) y = −one fourth(x − 5)2 + 1
Answer:
The answer is below
Step-by-step explanation:
A parabola is the locus of a point such that its distance from a given line (directrix) and a fixed point (focus) is always the same.
The equation of a parabola with a horizontal line as directrix is given by:
(x - h)² = 4p(y - k)
where y = k - p is the directrix and the focus = (h, k + p)
Given that parabola has a directrix at y = 2 and a focus at (5, 0)
Therefore:
y = k - p
k - p = 2 (1)
focus = (h, k + p) = (5, 0)
h = 5, k + p = 0
k + p = 0 (2)
Solve equation 1 and 2 simultaneously by adding both equations together:
2k = 2
k = 1
Substitute k = 1 in k + p = 0 to find p:
1 + p = 0
p = -1
Therefore h = 5, p = -1 and k = 1
Substitute the values of h, k and p into the equation of a parabola:
(x - h)² = 4p(y - k)
(x - 5)² = 4(-1)(y - 1)
(x - 5)² = -4(y - 1)
x² - 10x + 25 = -4y + 4
-4y = x² - 10x + 21
4y = 10x - x² - 21
When renting a car, Rent-For-Less charges $50 for a deposit and $1.25 per mile. Cheap
Rides charges $1.30 per mile and a $40 deposit. At what number of miles will the costs
be equivalent?
Answer:
200miles
Step-by-step explanation:
Given data
Rent-For-Less
charges $50 for a deposit and $1.25 per mile
let the number of miles be x
and the total distance be y
y=50+1.25x-------------1
Cheap Rides
charges $1.30 per mile and a $40 deposit
y=40+1.30x-------------2
Equate 1 and 2 above we have
50+1.25x=40+1.30x
collect liker terms
50-40= 1.3x-1.25x
10=0.05x
divide both side by 0.05
x= 10/0.05
x=200 miles
Hence the distance in miles is 200miles

Answer:
A. x = -3
B. x = 2
C. x = 9/10
Step-by-step explanation:
(A) –12x + 9 = –15x
Collect like terms
9 = -15x + 12x
9 = -3x
x = 9 / -3
x = -3
(B) 4.5x + 11.5 = 8.5x + 3.5
4.5x - 8.5x = 3.5 - 11.5
-4x = -8
x = -8 / -4
x = 2
(C) 23x – 9 = 13x
-9 = 13x - 23x
-9 = -10x
x = -9 / -10
x = 9/10
Answer:
A) x= -3
B) x = -2
C) x = 27

What a deal! Just deShirts is having a 20% off sale. Trixie rushes to the store and buys 14 shirts. When the clerk rings up her purchases, Trixie sees that the clerk has added the 5% sales tax first, before taking the discount. Trixie wonders whether adding the sales tax before the discount makes her final cost more than adding the sales tax after the discount. Without making any calculations, make a conjecture. Is Trixie getting charged more when the clerk adds sales tax first? The next few problems will help you figure it out for sure.
Does it matter if sales tax is added before the discount or after her final total? (Yes or no AND why or why not?)
Answer:
no because she would get the same total if she added it before or after

Elijah is planning a circular flower garden with a 12 foot diameter. He will put plastic edging along the flowerbed. How many feet of edging will Elijah need to enclose his flower garden? Round to the nearest tenth place. (Use 3.14 for π)
Answer:
[tex]37.7\ \text{foot}[/tex]
Step-by-step explanation:
The length of the edging will be equal to the circumference of the circular flower garden.
Here, the diameter of the circular garden is [tex]d=12\ \text{foot}[/tex]
Circumference of a circle is given by
[tex]C=\pi d\\\Rightarrow C=3.14\times 12\\\Rightarrow C=37.68\approx 37.7\ \text{foot}[/tex]
The length of the edging is [tex]37.7\ \text{foot}[/tex].
