Answer:
4x + y = 500
Step-by-step explanation:
Given:
Volume of water = 500 gallons
Water drained rate = 4 gallon per hour
Find:
Equation
Computation:
Total volume of water left in tank = y
Number of hour water drained = x
So,
Volume of water - Total volume of water left in tank = Water drained rate[Number of hour water drained]
500 - y = 4x
So,
Water drained;
4x + y = 500
Answer:
The correct equation would be y = 4x - 500.Step-by-step explanation:
y = The number of gallons in the tank after being drained for x hours
x = The number of hours that the tank is being drained
500 = The number of gallons in the tank
4 gallons = the number of gallons that are being drained per hour
y = 4x - 500
Correct answer: 0 = 4 (125) - 500
500 / 4 = 125

Answer:
4 to 1
Step-by-step explanation:
The greatest common factor between 8 and 2 is 2. So 2 will go into 8, 4 times. And 2 will go into 2, 1 time. So simplified the equivalent ratio is 4:1.
Question Hannah wanted to investigate whether there was a difference in the time spent in the checkout line between two grocery stores in a large city. She went to Grocery Store J on a Monday morning and recorded the time, in minutes, it took 30 customers to go through a checkout line. Then she went to Grocery Store K on Monday afternoon and recorded the time it took 30 customers to go through a checkout line. Hannah calculated the mean number of minutes for the customers in each line. She intends to conduct a two-sample t-test for a difference in means between the two stores. Have all conditions for inference been met?
Answer:
Yes. All the conditions for inference have been met.
Step-by-step explanation:
The conditions for inference are:
a) The sample must be random. The selections of the 30 customers in each Grocery Store were not biased in any way.
b) The sampling distribution must be approximately normal.
c) The observations of the samples were independent.
d) Adequate of sample size. 30 customers represent an adequate sample
e) The variances are not known as they were disclosed in this case.

Answer:
5 cups is greater then 32 fl oz
Step-by-step explanation:
First, we change fl oz to cups, for it is easier to do.
Next, when we change 32 fl oz, it is going to be
32 fl oz=4 cups
Last, it is obvious that 5 cups is greater than 32 fl oz.

has a mass of 5.2 x 10-3 kg. What is the total
mass, in kilograms, of the nails the carpenter
bought. Express your answer as a decimal.
Answer:
4.42
Step-by-step explanation:
5.2 x 10-3 multiplied by 850. I got it right on my assignment
The mass of the 850 nails is 442 x 10⁻² kilograms.
What is multiplication?The mathematical operation of multiplication is arithmetic. Additionally, it involves repeating the same forms of statements.
Example: 2 + 3 signifies that 2 is multiplied by 3 or that 3 is multiplied by 2 times.
A carpenter bought 850 nails.
Each nail has a mass of 5.2 x 10-3 kg.
To find the total mass:
Use multiplication operation,
850 x 5.2 x 10⁻³
= 4420 x 10⁻³
= 442 x 10⁻²
Therefore, the mass is 442 x 10⁻² kilograms.

Use the information giving in the figure to find the length FH. If applicable, round your answer to the nearest whole number.
The lengths on the figure are not drawn accurately.
9514 1404 393
Answer:
FH = 16
Step-by-step explanation:
ΔGHE is a 5-12-13 triangle.
ΔEHF is a 3-4-5 triangle with a scale factor of 4, so side FH is 4·4 = 16 units.
_____
(3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17) are all commonly used Pythagorean triples. The first two on the list are used in these triangles.
If you like, you can work out the numbers using the Pythagorean theorem, which tells you the square of the hypotenuse is equal to the sum of the squares of the other two sides.
For ΔEHG, that is ...
GE² = EH² + HG²
13² = EH² + 5²
EH² = 13² -5² = 169 -25 = 144
And for ΔEHF, ...
FE² = EH² +HF²
20² = 144 + HF²
400 -144 = HF² = 256
HF = √256 = 16
The length of side FH is 16 units.

A dog is fed 3 1/2 cups of food. A puppy is fed 3/5 of that. How much is the puppy fed?
Answer:
9 puppies can be fed.Step-by-step explanation:
Given that:
A dog is fed 312 cups of food. A puppy is fed 35 of that.To Find:
How much is the puppy fed?Let us assume:
x puppies can be fed.Finding the number of puppy:
Puppy : Food = Puppy : Food
⟶ 35 : 1 = 312 : x
⟶ 35/1 = 312/x
Cross multiplication.
⟶ 35x = 312
⟶ x = 312/35
⟶ x = 9 (approx.)
Hence,

Answer:
t=2.24 for khan
Step-by-step explanation:
The test statistic for the Adam's test is 2.24.
What is Test Statistic?Test statistic is a value calculated from a statistical test of hypothesis. It describes the closeness of the observed data with the expected distribution under the null hypothesis.
The formula to find the test statistic is,
t = (x - μ) / (s / √n)
Here x is the sample mean, μ is the population mean, s is the standard deviation and n is the sample size.
Given,
x = 208, μ = 200, s = 25 and n = 49
Substituting the values,
t = (208 - 200) / (25 / √49)
= (8 × 7) / 25
= 2.24
Hence the test statistic is 2.24.

What is the area of this square?

B= 48
C= 72
D= 144
No links, docs, files, drives etc
I will mark the correct answer brainlyest
You earn many points
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.

Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.

Cheetahs have been clocked at a top speed of approximately 102.6 ft/s. Gazelles are a main
part of a cheetah's diet. Gazelles have been clocked at a top speed of approximately 73.3 ft/s.
Suppose a cheetah sees a gazelle across the plains of Africa, 500 feet away, and begins to
run after it. The gazelle spots the cheetah and begins running at the same time the cheetah
does.
Determine how many seconds later the cheetah catches the gazelle. How many feet did the
cheetah have to run to catch the gazelle? Round to the nearest tenth of a foot. Show all your work.

Answer:
17.1 seconds1750.9 feetStep-by-step explanation:
The distance from the cheetah's starting point (in feet) can be modeled by ...
for the cheetah
c = 102.6t
for the gazelle
g = 73.3t +500
When these are equal, the cheetah will have caught the gazelle:
c = g
102.6t = 73.3t +500
29.3t = 500
t = 500/29.3 ≈ 17.1 . . . . . . seconds
The distance at that time is ...
c = 102.6(17.0648) ≈ 1750.9 . . . . feet

Additional comment
The cheetah can maintain top speed only for about 10 seconds. At 500 ft distance, the gazelle is pretty safe.
