A road toll is 3¢ for 5 kilometers. How much for 125 kilometers?
Answer:i think it would be 75 cents
Step-by-step explanation:
125 divided by 5 and you get 25, then you fo 25 times 3
Answer:
75 cents
Step-by-step explanation:
x= 5 kilometers
y= 3 cents
y/x= rate of change
3/5= 0.6
125 kilometers is the x variable so y= 0.6(125)
y= 75

Myra combined the like terms in the algebraic expression correctly. Which statement correctly describes what Myra did?
8 x squared + 7 minus 2 x squared + x
Answer:
The answer would be the first one, combining 8 and -2
Step-by-step explanation:
This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)
If you combine these you will get 6x^2 [8+(-2)=6]

Jada walks up to a tank of water that can hold up to 15 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 12 gallons of water. Five minutes later, the tank contains 10 gallons of water.
Type your answers in the blanks below.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
How many more minutes will it take for the tank to drain completely?
________minutes
How many minutes before Jada arrived was the water take completely full?
_________ minutes
Answer:
A) -2/5 gal/min
B) 25 minutes
C) 7.5 minutes
Step-by-step explanation:
A) We are told that the tank contains 12 gallons of water when Jada first sees it.
5 minutes later, it loses two gallons to become 10 gallons.
Thus, rate at which the amount of water in the tank changing = -2/5 gal/min
B) After 5 minutes it contains 10 gallons. Since it drains at 2/5 gal/min, let us say the time to finish draining all is x, thus;
2/5 • x = 10
x = 10 × 5/2
x = 25 minutes
C) When full, it can hold up to 15 gallons. This is 3 more than the 12 she saw when she arrived.
Thus;
2/5 • y = 3
y = 5 × 3/2
y = 7.5 minutes
Find an explicit formula for the geometric sequence below.
Answer:
see explanation
Step-by-step explanation:
The nth term ( explicit formula) of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 2 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{\frac{4}{3} }{-2}[/tex] = - [tex]\frac{2}{3}[/tex] , then
[tex]a_{n}[/tex] = - 2 [tex](-\frac{2}{3}) ^{n-1}[/tex] ← explicit formula
Answer:
Step-by-step explanation:
The formula for an explicit geometric formula (as opposed to a recursive one) is
[tex]a_n=a_1(r)^{n-1}[/tex] where a(n) is representative of the position of a number in the sequence, a(1) is the first number in the sequence, and r is the common ratio. The common ratio is the same number that must be either multiplied in or divided out to get to the next number in the term. Notice that the top numbers in our sequence are doubling which implies we are multiplying the top numbers by -2, and the bottom numbers are going up by multiples of 3. So our common ratio is -2/3. Try it and see:
[tex]-2(-\frac{2}{3})=\frac{4}{3}[/tex] and
[tex]\frac{4}{3}(-\frac{2}{3})=-\frac{8}{9}[/tex] etc.
Therefore, the explicit geometric formula for this sequence is
[tex]a_n=-2(-\frac{2}{3})^{n-1[/tex]
You can use this formula to find any number in the sequence; for example, if you wanted to know the 100th number in this sequence, simply replace n with 100 and do the math. That's what an explicit formula is used for.

Complete Question
Talia attended a 5 -day math camp that lasted 5/6 of an hour each day. How many hours did Talia spend at the math camp?
Answer:
4 1/6 hours
Step-by-step explanation:
1 day = 5/6 hour
5 days = x
Cross Multiply
x = 5/6 × 5 days
x = 25/6 hours
x = 4 1/6 hours
Therefore, Talia spent 4 1/6 hours at camp.

what is the radius of the cone?
Answer:
r = 6 in
Step-by-step explanation:
[tex]V = \pi r^{2} \frac{h}{3}[/tex] = [tex]216\pi[/tex]
r²h/3 = 216
r² (18/3) = 6 r² = 216
r² = 216/6 = 36
r = 6

5. The lengths of the legs of a right triangle are 4.5 inches and 6 inches. What is the length of the hypotenuse?
Answer:
The hypotenuse is (root) 84.25
Step-by-step explanation:
4.5^2 + 6^2 = x^2 (hypotenuse)
20.25 + 36 = 84.25
x^2 = 84.25
x = (root) 84.25 or 9.1787...

What is the scale factor of the drawing if the scale is 1 inch equals 6 feet?
Answer:
The scale “1 inch to 6 feet” is equivalent to the scale “1 to 72,” because there are 72 inches in 6 feet. The scale “1 to 100” would make a scale drawing that is smaller than the scale “1 to 72,” because each inch on the new drawing would represent more actual length.

An article costing GH 2000.00 is sold at a
profit of 60%. Calculate the selling price
of the article.
Answer:
GH 5000
Step-by-step explanation:
Given data
Cost price= GH 2000.00
Percent profit= 60%
Sales price =???
The sale price can be found as
% profit= sale-cost/sale*100
60= sale-2000/sale*100
60= 100*sale-200000//sale
60*sale= 100sale-200000
1000sale-60sale= 200000
40sale= 200000
sale= 200000/40
sale= 5000
Hence the sales price = GH 5000

Answer:
D
Step-by-step explanation:
the center is (0,8)
(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))
the radius is 7 (or √49)
