Two snails climbed up a tree at a constant rate. A person measured and recorded their respective distances above the ground. • Snail A was 12.5 inches above the ground at 10 minutes and 16 inches above the ground at 24 minutes. • Snail B started at 3 inches above the ground and climbed 0.3 inch per minute. The snails continued at the same speeds. • Determine the amount of time, in minutes, it took for the two snails to be the same distance above the ground. • Include an equation to represent each snail's distance above the ground, y, in terms of x, the minutes elapsed since the measurement started. Show your work or explain your answer.
Answer:
140 minutes
Step-by-step explanation:
Using m = (y₂ - y₁)/(x₂ - x₁) , we find the rate at which Snail A moves which is also the gradient of the line with which it moves. Given that Snail A was 12.5 inches above the ground at 10 minutes and 16 inches above the ground at 24 minutes, x₁ = 10 min, y₁ = 12.5 inches, x₂ = 24 min and y₂ = 16 inches.
So, m = (y₂ - y₁)/(x₂ - x₁)
m = (16 - 12.5)/(24 - 10) = 3.5/14 = 0.25
Also, the equation of the line,
(y - y₁)/(x - x₁) = m
(y - 12.5)/(x - 10) = 0.25
cross-multiplying, we have
y - 12.5 = 0.25(x - 10)
expanding the bracket, we have
y - 12.5 = 0.25x - 2.5
adding 12.5 to both sides, we have
y - 12.5 + 12.5 = 0.25x - 2.5 + 12.5
y = 0.25x + 10
Since Snail B started at 3 inches above the ground and climbed 0.3 inch per minute. The snails continued at the same speeds, its distance y moved is y = 0.3t + 3
We now find the time x it takes the snails to cover the same distance by equating both expressions. So,
0.25x + 10 = 0.3x + 3
collecting like terms, we have
10 - 3 = 0.3x - 0.25x
7 = 0.05x
0.05x = 7
x = 7/0.05
x = 140 minutes

What is translation?It is the movement of the shape in the left, right, up, and down direction.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,

smeone invests £800 at a rate of 2% simple interest per year. Work out the amount of interest she receives after three years.
Answer:
£48
Step-by-step explanation:
I=Prt
I=(800)(0.02)(3)
I = 48
Answer:
the simple interest earned was £48.
Step-by-step explanation:
the appropriate simple interest formula is i = prt, where r is the annual interest rate as a decimal fraction. Here, with prt = (£800)(0.02)(3 yr), we find that the simple interest earned was £48.
The ratio of red to blue marbles in a bag is 2:5. If there are 65 blue marbles in the bag, how many red marbles are there? Let x represent the number of red marbles. Set up a proportion and cross multiply to solve.
Answer:
first get the total ratio; 2 + 5 = 7
so the fraction of blue marbles is 5/7
then assume the number of total marbles to be k
then use the expression;
5/7*k = 65
7*5/7 * k = 65*7
5k =455
5/5k = 455/5
k = 91
then calculate the number if red marbles from;
x = 2/7*91
x = 26
Therefore there are 26 red marbles.
i need help solving the paint questions
For S if the ratio is 2:7 and you use 20 drops of red paint you multiply 2 by 10 which is 20 so you also multiply 7 by ten to get 70 (So the answer for S is 70 drops) and for L you multiply 2 by 20 to get 40 so you multiply 7 by 20 and you get 140 (The answer for L is 140 drops) For T you multiply 2 by 1.5 to get 3 so you multiply 7 by 1.5 which is 10.5 ( so the answer for T is 10.5 drops)

Question 10 of 20. POOS The dimensions of a right rectangular prism are shown below. 1 in. How many cubes with side lengths of inch are needed to fill the prism without gaps or overlaps? 36 cubes 91 cubes 216 cubes 546 cubes
Answer:
546
Step-by-step explanation:
From the attached picture ;
Volume of a rectangular prism = (width * length * height)
Volume = 2 1/6 * 1 1/6 *1
Volume =. 13/6 * 7/6 * 1
Volume = 91 / 36 in³
Side length, a of cube = 1/6
Volume of cube = a³ = (1/6)^3 = 1/216
(91/36) ÷ 1/216
91/36 * 216/1
91 * 6 = 546

SU and VT are chords that intersect at point R. A circle is shown. Chords S U and V T intersect at point R. The length of S R is x + 6, the length of R U is x, the length of V R is x + 1, and the length of R T is x + 4. What is the length of line segment VT? 4 units 8 units 13 units 14 units
Answer:
13unitsStep-by-step explanation:
If SU and VT are chords that intersect at point R, then;
SR/RT = VR/RU and VT = VR + RT
Given the following
SR= x+6
RU = x
VR = x+1
RT = x+4
Substitute into the expression above;
x+6/x+4 = x+1/x
Cross multiply
x(x+6) = (x+1)(x+4)
Expand
x^2+6x = x^2+4x+x+4
x^2+6x = x^2+5x+4
x^2 will cancel out from both sides
6x = 5x+4
6x-5x = 4
x = 4
Get VT
VT = VR + RT
VT = x+1 + x+4
VT = x+x+1+4
VT = 2x+5
Since x = 4
VT = 2(4) + 5
VT = 8+5
VT= 13 units
Hence the length of the line VT is 13units

Which function represents this sequence?
A.
f(n) = 4 ∙ 2n-1
B.
f(n) = 4n-1
C.
f(n) = 2 ∙ 4n-1
D.
f(n) = 2n-1
Answer: A. f(n) = 4 ∙ 2n-1
Step-by-step explanation:
because the 1st term is 4 according to your image, and then you will have to multiply that by its common difference and using your table, to get from 4 to 8 then 8 to 16 you would multiply by 2, and you would finally multiply that by n or known as the number of terms and 1 making the equation. f(n) = 4 ∙ 2n-1 I hope this is very helpful for everyone.

ABCD is a parallelogram. AB = 2x, AD = 4y - 6, BC = 3x. If the perimeter of ABCD is 180, find the values of x and y
Answer and Step-by-step explanation:
AB = DC = 2x
AD = BC = 4y - 6 = 3x
180 = 2x + 2x + 3x + 3x = 10x
18 = x
4y - 6 = 3(18)
4y = 54 + 6
4y = 60
y = 15
18 = x
15 = y
2(18) + (4(15) - 6) + 3(18) + 2(18) = 36 + 36 + 54 + 54 = 180

Step 5.
Apply the radical rule. [tex]\sqrt{ab}=\sqrt{a}\sqrt{b}, a\geq 0, b\geq 0[/tex]
[tex]\sqrt{2^2}\sqrt{2}[/tex]
Step 6.
Apply the radical rule again. [tex]\sqrt{a^2}=a, a\geq 0[/tex]

Sue bought a total of 12 candy bars at the store. Some cents cost 50 cents each and the rest cost 75 cent each. Write an expression to represent. a. The number of 75 cent bars if she bought y 50 cent bars b. The total cost, in cents, for all of the bars.
Answer:
According to this, the answer is:
a. x=(c-0.50y)/0.75
b. c=0.75x+0.50y
Step-by-step explanation:
With the information provided, the total cost in cents is equal to the result of the price of the 75 cent bars for the amount of bars plus the price of the 50 cent bars for the amount of bars, which would be:
c=0.75x+0.50y, where:
x is the amount of the 75 cent bars
y is the amount of the 50 cent bars
Now, you can solve for x to determine the expression that represents the number of 75 cent bars if she bought y 50 cent bars:
c-0.50y=0.75x
(c-0.50y)/0.75=x
x=(c-0.50y)/0.75
According to this, the answer is:
a. x=(c-0.50y)/0.75
b. c=0.75x+0.50y
