x is Interest
P is Principal
3% is the rate
Need answer for h!!!!
Answer:
h = (100x) / (3p)
Step-by-step explanation:
[tex]I=\frac{PRT}{100} \\[/tex]
where,
I is the interest which is given by x
P is the principal amount which is given by p
R is the rate which is given 3% and
h is the time so,

Nicole and her friend Ana like to go out running for exercise. If Nicole ran 3 25 miles and Ana ran 2 34 miles on Saturday, what is the total number of miles run by the girls on Saturday?
Answer:
6.15 miles
Step-by-step explanation:
Step one:
given data
Nicole ran 3 2/5 miles and

Find the x−and y−intercepts. −2x − 5y = 20
Answer:
X=10, Y=4
Step-by-step explanation:
Along the y-axis, x = 0.
2(0) + 5y = 20
5y = 20
y = 4
Your y-intercept is at (0,4).
Along the x-axis, y = 0
2x + 5(0) = 20
2x = 20
x = 10
Your x-intercept is at (10,0).
Answer:
-2x-5y=20 (if x= 2 )
[tex] - 2 \times 5 - 5 \times y = 20 [/tex]
[tex] - 20 - 5 \times y = 20[/tex]
[tex] - 5 \times y = 40[/tex]
[tex]y = 8[/tex]
0.40 X plus 20 < 200 which best describes a number of bars that the band can order 0.40 X plus 20 < 200 which best describes a number of borrowers that can be ordered
Answer:
So x can have values from zero to 449
Step-by-step explanation:
0.40 X plus 20 < 200
0.4x +20 < 200
Putting the values of x for 0,1,2,
0.4x +20 < 200
0.4(0) +20 < 200
20< 200
0.4x +20 < 200
0.4(1) +20 < 200
20.4 <200
0.4(2) +20 < 200
20.8 <200
The maximum value which x can have is less than 450 because 450 would give a number equal to 200 and we have the inequality of a number being less than 200
0.4x +20 < 200
0.4(450) +20 < 200
180+20< 200
200 <20 which is wrong.
So x can have values from zero to 449
0.4x +20 < 200
0.4(449) +20 < 200
179.6+20< 200
199.6 <200
X can have the values fom 0 to 449.

A group of 9 workers was assigned to paint the walls in a house, which could be completed in 48 hours. However, after working 8 hours, some of the workers left the group and the remaining workers could complete the job in 72 hours. How many workers left the team?
Plz write equation:0
Answer: 4 workers
==============================================
Explanation:
We have 9 workers painting walls in a house. Let's say the total square feet needed to be painted is 9000 square feet. I picked some arbitrary large multiple of 9, so that it leads to 9000/9 = 1000 square feet per worker.
In other words, each worker paints 1000 square feet.
They can do the job in 48 hours, which means their rate is 1000/48 = 125/6 square feet per hour approximately.
After 8 hours, each worker paints 8*(125/6) = 500/3 square feet. So all 9 workers painted 9*(500/3) = 1500 square feet
Put another way: they got 8/48 = 1/6 of the job done after 8 hours, so (1/6)*9000 = 1500 sq feet of wall has been painted so far. This leaves 9000-1500 = 7500 sq ft unpainted.
------------------------------------------------
Let x be the number of workers that leave.
There are 9-x people still on the job.
The 7500 sq ft of left over wall is divided among the 9-x people. Each worker gets 7500/(9-x) sq feet of wall to paint.
Earlier we found each worker's rate was 125/6 sq ft per hour. If they complete the remaining job in 72 hours, then,
(rate)*(time) = (amount of job done)
(125/6)*(72) = 7500/(9-x)
1500 = 7500/(9-x)
1500(9-x) = 7500
9-x = 7500/1500
9-x = 5
-x = 5-9
-x = -4
x = 4
4 workers went home.
If 4 workers went home, then 9-4 = 5 workers remain
They each have 7500/5 = 1500 sq ft of wall to paint, which helps confirm the answer.
Two years ago, the water level in a local reservoir fell 834 feet. Last year, the water level rose 435 feet. By how many feet did the water level of the reservoir change overall during these two years?

What is unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Two years ago, the water level in a local reservoir fell 834 feet.
Last year, the water level rose 435 feet.
So, the water level of the reservoir change overall during these two years
= -834 + 435
= -399
Hence, the water is 399 feet fell.

Anyone help me ASAP, its due in an hour, plz show all the working, THANK YOU SO MUCH
Answer:
Step-by-step explanation:
First, start out with the parent function:
[tex]y = b^{x}[/tex]
Now, we look at the transformations, and make the equation.
We see that the graph shifted down 4 units, since the graph's horizontal asymptote is at y = -4.
[tex]y = b^{x} - 4[/tex]
We see point (0, -3) to point (1, -1). The value of b would be 3. The reason is that when you plug 0 in, you get 1, then 1 - 4 equals 3. (0, -3),
Then, when you plug in 1, you get 3, then 3 - 4 equals -1. This matches up with the graph.
This is the answer:
[tex]y = 3^{x}-4[/tex]

The following proportion could be used to change from gallons to which measure.
1/4 x 3/x
A. ounces
B. pints
C. quarts
D. gallons
Answer:
Choice C. quarts
Step-by-step explanation:
In one gallon there is 8 pints, 16 cups, and 4 quarts. So if the proportion was set up like this [tex]\frac{1gallon}{4quarts}*\frac{3gallons}{xquarts}[/tex] it's likely that they are looking for how many quarts are in 3 gallons, and since we now know that 4 quarts is one gallon we can multiply 3 and 4 to get 12. So in 3 gallons there's 12 quarts.
