Answer: x = 13
Step-by-step explanation: the equation to solve this is:
4 × (4 + 8) = 3 × (3 + x)
so we solve the first half of that:
4 × (4 + 8)
4 × 12
48
now we have:
48 = 3 × (3 + x)
so we switch the sides to make it easier and solve
3 × (3 + x) = 48
divide both sides by 3
3 × (3 + x) ÷ 3 = 48 ÷ 3
and get
3 + x = 16
now subtract 3 from both sides
3 + x = 16
-3 -3
and finally we get
x = 13
hope this helped :)

The function f(x) = x2+ 4 is defined over the interval [-2, 2]. If the interval is divided into n equal parts, what is the height of the right endpoint of the k^th rectangle?
Answer:
Following are the responses to the give question:
Step-by-step explanation:
The [tex]f(x) = x^2 + 4[/tex] model is developed in the interval [tex](-2, 2)[/tex] total equal in a between such a range[tex]= 5[/tex].
Its right endpoint of every rectangle is separated onto n equal parts by the height [tex]= \frac{5}{n}.[/tex]
Height of endpoint [tex]= \frac{5}{n}[/tex] of the k rectangles therefore, the height of the kth rectangle = First rectangle height + K rectangle height
[tex]= -2 +k \times \frac{5}{n}\\\\[/tex]
Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change
Answer:
The price per cheese stick was increased by 150%.
The amount of cheese sticks per $1.00 has decreased by 60%.
Step-by-step explanation:
The price per cheese stick was $0.10
1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10The current price per cheese stick is $0.25
1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25That means the price per cheese stick was raised by 150%.
That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.
Find the total lateral area of the following
cone. Leave your answer in terms of .

3 cm
LA = [ ? ]cm?
Hint: Lateral Area of a Cone = tre
Where e = slant height
Answer:
Step-by-step explanation:
Answer:
200π cm^2
Step-by-step explanation:
Sb = 8^2 π = 64π cm^2
a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm
Sl = 8x17xπ = 136 π cm^2
SA = 136π + 64π =200π cm^2

4600 X 1.04 to the power of 7?????
Answer:
6053.28618448
no is the power of 6
Answer:
4784 to the power of 7
Step-by-step explanation:
i'm not sure if i interpreted what you wrote correctly, but if its ((4600*1.04)to the power of 7), then my answer would be correct.
if it was 4600*1.04 (where 1.04 would be to the power of 7), then the answer would be about 6053.28618, or 4600*26 to the power of 7/ 25 to the power of 7

A quantity with an initial value of 650 grows exponentially at a rate of 20% every week. What is the value of the quantity after 70 days, to the nearest hundredth?
Answer:
4024.62
Step-by-step explanation:
the value in 70 days can be determined using his formula
FV = P (1 + r)^n
FV = Future value
P = Present value = 650
R = growth rate = 20%
N = number of weeks = 70 / 7 = 10 weeks
650 x (1.2)^10 = 4024.62
Answer:
The Answer is 4024.62

Oliver drove 278 miles in 4 hours how much hours does it take him to drive 139 miles
PLSSS HELP
Answer:
34.75 i think
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 2 \ hours}}[/tex]
Step-by-step explanation:
Let's set up a proportion to solve. Use the following setup:
[tex]\frac {hours}{miles}=\frac{hours}{miles}[/tex]
We know that it takes Oliver 4 hours to drive 278 miles.
[tex]\frac {4 \ hours}{278 \ miles}=\frac{hours}{miles}[/tex]
We don't know how long it takes him to drive 139 miles. Therefore, we use the variable x for hours, because it is unknown.
[tex]\frac {4 \ hours}{278 \ miles}=\frac{x \ hours}{139 \ miles}[/tex]
[tex]\frac {4 }{278 }=\frac{x \ hours}{139 }[/tex]
We are solving for x, the hours it takes him to drive 139 miles. The variable must be isolated. It is being divided by 139 and the inverse of division is multiplication. Multiply both sides of the equation by 139.
[tex]139*\frac {4 }{278 }=\frac{x \ hours}{139 }*139[/tex]
[tex]139*\frac {4 }{278 }={x }[/tex]
[tex]2=x[/tex]
It takes Oliver 2 hours to drive 139 miles.

8x - 5y =-18
2x + 5y = 58
Answer:
(4,10)
Step-by-step explanation:
8x - 5y = -18
+ 2x + 5y = 58
10x = 40
Dive both sides by 10.
x = 4
2x + 5y = 58
2(4) + 5y = 58
8 + 5y = 58
5y = 50
y = 10
