What is the area of this square?
A= 12
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.
B
If you do 4x12 you will end up with 48

For the annual rate of change, find the corresponding growth or decay factor: +15%
For the annual rate of change, find the corresponding growth or decay factor: -30%
For the annual rate of change, find the corresponding growth or decay factor: -70%
For the annual rate of change, find the corresponding growth or decay factor: +100%
Answer:
The growth factor for the annual rate of change of 15% is 1.15.
The decay factor for the annual rate of change of -30% is 0.7.
The decay factor for the annual rate of change of -70% is 0.3.
The growth factor for the annual rate of change of 100% is 2.
Step-by-step explanation:
Growth or decay factor:
The growth factor is 1 + r, r as a decimal.
The decay factor is 1 - r, r as a decimal.
For the annual rate of change, find the corresponding growth or decay factor: +15%
r = 0.15, so 1 + 0.15 = 1.15.
The growth factor for the annual rate of change of 15% is 1.15.
For the annual rate of change, find the corresponding growth or decay factor: -30%
r = -0.3, so 1 - 0.3 = 0.7.
The decay factor for the annual rate of change of -30% is 0.7.
For the annual rate of change, find the corresponding growth or decay factor: -70%
r = -0.7, so 1 - 0.7 = 0.3.
The decay factor for the annual rate of change of -70% is 0.3.
For the annual rate of change, find the corresponding growth or decay factor: +100%
r = 1, so 1 + 1 = 2.
The growth factor for the annual rate of change of 100% is 2.

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.
PLEASE HELP!!!!!!!!!!!
Answer:
I think it's 18
Step-by-step explanation:
because I'm looking at 12/8 to be a ratio, that means that the size of the bigger figure had decreased by 12/8 or 1.5
then I divided the 27 by 1.5 to get the area of the small one which was 18.
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.

x = 2.25 ft = 2 1/4 ft
we substitute 2 1/4 for x
x = 2 1/4 ft
3 3/4 ft + 2 1/4 ft = 6 ft
6 ft = 6 ft
Since 6ft is equal to 6ft...
Blue picture
It is 2 1/4 ft long
we substitute 7/8 ft for x
since 2 1/4 ft is equal ...
Yellow picture
2 3/8 ft - 2 3/8 ft + x = 3 1/4 ft - 2 3/8 ft
x = 3 1/4 ft - 2 3/8 ft
x = 7/8 ft
Check
x = 7/8 ft
2 3/8 ft + 7/8 ft = 3 1/4 ft
3 3/8 ft - 3 3/8 ft + x = 4 1/4 ft - 3 3/8 ft
x= 4 1/4 ft - 3 3/8 ft
x = 7/8 ft
check
x = 7/8 ft
3 3/8 ft + 7/8 ft = 4 1/4 ft
red picture
4 3/8 ft - 4 3/8 ft + x = 5 1/4 ft - 4 3/8 ft
x = 5 1/4 ft - 4 3/8 ft
x = 7/8 ft
check
x = 7/8 ft
4 3/8 ft + 7/8 ft = 5 1/4 ft

A carpenter bought 850 nails. Each nail
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.

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.

A line has a slope of 2 and passes through the point
(-4,3). What is an equation of the line?
Pect the right option from the below but
y = -21 - 5
I
y = -22 - 2
y = -2+ + 2
y = -23 + 3
y = -20 +5
Answer:
y = 2x + 11
Step-by-step explanation:
The point slope formula for a line is
y - y1 = m(x - x1)
We already have the slope, 2, and we can substitute the point (-4, 3) into (x1, y1):
y - 3 = 2(x + 4)
y - 3 = 2x + 8
y = 2x + 11
