Step-by-step explanation:
Wil has a coin collection and is currently adding 9 coins per day to his existing number of coins in his collection.After 22 days he has a total of 218 coins. How many coins will he have after 36 days?
Answer:
344
Step-by-step explanation:
Number of coins added per day in the collection = 9
Number of coins in the collection after 22 days = 218
To find:
Number of coins in the collection after 36 days.
Solution:
First of all, let us find how many coins did he have initially.
Let the number of coins present initially with Wil = [tex]x[/tex]
Number of coins added per day = 9
Number of coins added after 22 days = 22 [tex]\times[/tex] 9 = 198
Therefore,
[tex]x + 198 = 218\\\Rightarrow x = \bold{20}[/tex]
Number of coins present with Wil initially = 20
Number of coins added after 36 days = 36 [tex]\times[/tex] 9 = 324
Total number of coins after 36 days = Number of coins present initially with Will + Number of coins added = 324 + 20 = 344

A watering can dispenses water at the rate of 0.3 gallon per minute. The original volume of water in the can was 7 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water? (1 point)
{(1, 6.7), (2, 6.4), (3, 6.1)}
{(1, 7.0), (2, 6.7), (3, 6.4)}
{(6.7, 1), (6.4, 2), (6.1, 3)}
{(7.0, 1), (6.7, 2), (6.4, 3)}
Answer:
The correct ordered pairs are:
{(1, 6.7), (2, 6.4), (3, 6.1)}
Option A is correct.
Step-by-step explanation:
A watering can dispenses water at the rate = 0.3 gallon per minute
The original volume of water in the can = 7 gallons.
Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water?
First making the function:
The the volume of water in the can in gallons is represented by y and time in minutes is represented by x. Initially the volume is 7 gallons, after than water dispense at rate of 0.3 gallon per minute so, the function will be:
y=7-0.3(x)
Now, putting values to find ordered pairs
So, when time is 1 minute i.e x = 1
y=7-0.3(1)
y=7-0.3
y=6.7
So, when x=1, y=6.7 the ordered pair is: (1,6.7)
when time is 2 minutes i.e x = 2
y=7-0.3(2)
y=7-0.6
y=6.4
So, when x=2, y=6.4 the ordered pair is: (2,6.4)
when time is 3 minutes i.e x = 3
y=7-0.3(3)
y=7-0.9
y=6.1
So, when x=3, y=6.1 the ordered pair is: (3,6.1)
So, the correct ordered pairs are:
{(1, 6.7), (2, 6.4), (3, 6.1)}
Option A is correct.

Write the equation of the line that is perpendicular to y = 3x - r and that has the same y - intercept .
WILL MARK BRAINLIEST
Answer:
y= -(1/3)x -r
Step-by-step explanation:
a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.
In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.
The problem states the line has the same y-intercept so it has to still be -r.
So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

solve for x. 3(x- 4)=15x
Answer:
x=-1
Step-by-step explanation:
3(x−4)=15x
Use the distributive property to multiply 3 by x−4.
3x−12=15x
Subtract 15x from both sides.
3x−12−15x=0
Combine 3x and −15x to get −12x.
−12x−12=0
Add 12 to both sides. Anything plus zero gives itself.
−12x=12
Divide both sides by −12.
x=
−12
12
Divide 12 by −12 to get −1.
x=−1
Answer:
[tex]3(x- 4)=15x[/tex]
[tex]3x-12=15x[/tex]
[tex]3x-12+12=15x+12[/tex]
[tex]3x=15x+12[/tex]
[tex]3x-15x=15x+12-15x[/tex]
[tex]-12x=12[/tex]
[tex]\frac{-12x}{-12}=\frac{12}{-12}[/tex]
[tex]x=-1[/tex]

Question 5 of 17
Which steps show how to use the distributive property to evaluate9 - 67?
O A. 9(67) = 9(70 - 3) = 9 . 70 +9-3 = 630 + 27 = 657
O B. 9(67) = 9(70
OC. 9(67) = 9(70 – 3) =9 .70 – 3 = 630 - 3 = 627
OD. 9(67) = 9(70– 3) = 9.70- 70 3 = 630 - 210 = 420
3) =9.70 -93= 630 -27 = 603
While taking a ride in a hot-air-balloon in Napa Valley, Francisco wonders how high he is. To find
out, he chooses a landmark on the ground that is to the east of the balloon and measures the angle of
depression to be 54°. A few minutes later, after the balloon floats horizontally 100 feet east, closer to the
landmark, the angle of depression to the same landmark is determined to be 61°. Determine the height h
of the balloon. Round your answer to the nearest tenth.
a) Find the measures of ∠1, ∠2, ∠3 and ∠4:
∠1 = ________ ∠2 = ________
∠3 = ________ ∠4 = ________

3/5 divided by what makes 3/10
I will make it the brain lieset answer
Answer:
5
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
We will use the KFC method to figure out the answer:
3/5 ÷ 2/1
We keep the first fraction
3/5 ÷ 2/1
Flip the last fraction (swap the numbers)
3/5 ÷ 1/2
Change the sign (to a multiplication symbol)
3/5 x 1/2
Then, finally, to solve for the answer, we multiply across (3 x 1 and 5 x 2).
3 x 1 = 3
5 x 2 = 10
The answer is 3/10 because it cannot be simplified any further.

Sita and Radha purchased a car for rupees 320000 due to some economic problem they sold it for 280000.find the loss incured and loss percentage
Answer:
40000 and 12.5% respectively
Step-by-step explanation:
soln:
given,
cost price(c.p)=320000
selling price(s.p)=280000
loss(l),loss percentage(l%)=?
we know,
l=c.p-s.p
or,l=320000-280000
•°•l=40000
now,
l%=l/c.p*100%
or,l%=40000/320000*100%
•°•l%=12.5%

yes it's on a 1.5 scale factor.....I think. The question you put at the top threw me off at first but the picture makes sense. I'm not entirely sure if this is right but if you adjust the triangle to be the same way as the other one then you will see which sides correspond to each other. Each number can be multiplied by 1.5 to get the number that is on the side of the other triangle that corresponds with it....if that makes any sense
