how is 3/4 bigger than 2/4
Answer:
3/4 is equivalent to .75 and 2/4 is equivalent to .50 so this shows .75 is greater than .50 allowing us to know 3/4 is greater than 2/4
Step-by-step explanation:
Answer:
Hey
Ok ima explain it in the most simple way
lets start with 2/4 if you count and do everything correctly 2 is halfway from 4 so its 50%. think of it this way 2/4 is 50% because 2 is only halfway to 4.
3 is more than half way to 4 because it is only up to 4. You can only do this method when the denominator is the same. 3/4 is bigger than 2/4 because 3 is bigger than 2.

What transformation takes the graph of g(x) = x2 – 5 to the graph of
h (x) = x² – 1
Answer:
We need the following translation: [tex]h(x) = g(x) +4[/tex]
Step-by-step explanation:
To transform [tex]g(x)[/tex] into [tex]h(x)[/tex], we need must apply the following translation:
[tex]h(x) = g(x) +4[/tex] (1)
If we know that [tex]g(x) = x^{2} -5[/tex], then the expression of [tex]h(x)[/tex] is:
[tex]h(x) = x^{2}-5 +4[/tex]
[tex]h(x) = x^{2}-1[/tex] (2)

The angle of elevation to the top of a flagpole is 50 degrees if the angle of elevation was measured 24 m from the flagpoles base wich expression can be used to find the height of the flagpole
Answer:
Tan 50 = H/24
Step-by-step explanation:
The set up will give a right angled triangle;
Given the following
angle of elevation = 50degrees
Distance of elevation from the flagpole base = 24m (Adjacent)
Required
Height of the flagpole (Opposite) = H
Using the SOH CAH TOA identity
Tan theta = opposite/adjacent
Tan 50 = H/24
H = 24tan50
H = 24(1.1918)
H = 28.60
Hence the required expression is Tan 50 = H/24 where H is the height of the flagpole
The height of the flagpole is 28.60.
Given
The angle of elevation to the top of a flagpole is 50 degrees.
The angle of elevation was measured 24 from the base of the flagpole.
The angle of elevation;The angle of elevation of the sun is the angle formed between the horizontal line and your line of sight when you look at the sun.
Let the height of the flagpole be H.
Then,
The height of the flagpole is given by;
[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\ \rm Tan50=\dfrac{H}{24}\\\\H = 24 \times tan50\\\\H = 24\times 1.91\\\\H=28.60[/tex]
Hence, the height of the flagpole is 28.60.

What is matrices?There are columns and rows in a matrix. The dimensions or size of a matrix are determined by these rows and columns. There are many different kinds of matrices, including row, column, null, square, diagonal, upper triangular, lower triangular, symmetric, and antisymmetric matrices.
Given two matrices,

We need to find the sum of this given matrices
The only matrices that may be added together are ones of the same size. As a result, you can only add matrices if they are both m × n. For example, you can add two or more 3 × 3, 1 × 2, or 5 × 4 matrices. You cannot add a 2 × 3 and a 3 × 2 matrix, a 4 × 4 and a 3 × 3, etc. The number of rows and columns of all the matrices being added must exactly match.
thus,
Sum of matrices = [tex]\left[\begin{array}{ccc}4 -8&19 +7 &-5 + 0\\7 -1&0 + 17&-14 +6\\\end{array}\right][/tex]
Sum of matrices = [tex]\left[\begin{array}{ccc}-4&26 &-5 \\6&17&-8\\\end{array}\right][/tex]

During the snow storm
feet of snow fell.
Answer:
Basically we need to add all of the inches
Step-by-step explanation:
so...
8 inch ( first day ) + 6 inch ( second day) + 9 inch ( third day )
add all those inches together what do you get?
23 inches in total. So altogether 23 inches of snow fell during the 3-day storm
Answer:
1.9
Step-by-step explanation:
A foot is 12 inches, add 8+9+6 you get 23 convert. 23 inches to feet you get 1.9 feet

W You deposit $9000 in a savings account that earns 3.6% annual interest compounded monthly. You also save $40 per month in a safe at home. Write a function C(t) =b(t) +h(t), where b(t) represents the balance of your savings account and h(t) represents the amount in your safe after t years. c(t) = Find and interpret C(5). C(5) = $
Answer:
C(5)= $13,172.05
Step-by-step explanation:
To calculate C(t), we need to divide the formula into two equations:
C(t) =b(t) +h(t)
b(t)= PV*(1+i)^n
n= number of months
i= monthly interest rate
PV= initial investment
h(t)= montlhy deposit* number of months
Now, for C(5); I assume its 5 years:
i= 0.036/12= 0.003
n= 5*12= 60
C(5)= 9,000*(1.003^60) + 40*60
C(5)= $13,172.05

On Monday Mrs. Wise bought 3 lbs of apples at $4 per lb. On Tuesday, apples were on sale for 20% off so she bought another 5 lbs. What was the price of apples on Monday?
Answer:
$12 on Monday
$16 on Tuesday
$28 in total
Step-by-step explanation:
Multiply the number of pounds by the cost per pound on Monday:
3 * 4 = $12 on Monday
If you want to find the price on Tuesday as well (I know it doesn't ask for it) you can calculate 20% of 4 by multiplying:
4 * 0.2 = 0.80
Next, subtract the 20% from the normal price:
4 = 0.80 = 3.20
Finally, multiply the discounted price by the number of pounds she bought:
3.20 * 5 = $16 on Tuesday
You can find the total of both Monday and Tuesday by adding the two together:
12 + 16 = $28.00 in total

The safety officers of a mining company take an SRS of 500500500 employees and finds that 15\, percent of the sampled employees wear contact lenses. The safety officers may take several more samples like this. Suppose it is really 12\, percent of the approximately 34{,}00034,00034, comma, 000 employees in the company who wear contact lenses. What are the mean and standard deviation of the sampling distribution of the proportion of employees who wear contact lenses
Answer:
The mean of the sampling distribution of the proportion of employees who wear contact lenses is 0.12 and the standard deviation is 0.0145.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
12% of the employees wear contact lenses.
This means that [tex]p = 0.12[/tex]
Samples of 500:
This means that [tex]n = 500[/tex]
What are the mean and standard deviation of the sampling distribution of the proportion of employees who wear contact lenses?
Mean:
[tex]\mu = p = 0.12[/tex]
Standard deviation:
[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.12*0.88}{500}} = 0.0145[/tex]
The mean of the sampling distribution of the proportion of employees who wear contact lenses is 0.12 and the standard deviation is 0.0145.
Bertie Beetke Walks so that he is always exactly 1.3 cm. Adam and walks so that he is always exactly 3.5 cm from crumb B the only two points at which they can meet, mark the points with crosses.
Answer:
I can not give an exact solution, because I can not draw in the given image and I don't know the scale of the image, but I can give a general way of solving this.
We know that a circle is a shape such that al the points are equidistant to the center.
So, if Bertie is always exactly 1.3cm from crumb A, then all the possible positions of Bertie are shown by a circle of radius = 1.3cm around crumb A.
And if Adam is always exactly 3.5cm away from crumb B, then the possible positions of Adam are shown by a circle of radius = 3.5cm around crumb B.
So to solve this problem, you need to draw these two circles, and the points where the circles intersect each other will be the points where Bertie and Adam could meet.
