Answer:
One number is 29, and the other one 45
Step-by-step explanation:
Solve this problem by creating two equations that represents the statements, and solve for the unknowns using substitution:
Let's say that one of the numbers is X , and the other one Y, and assume that Y is larger than X, so when we do their difference we get the 16 units they mention in the problem:
Y - X = 16
The info on the product of the two numbers will give us our second equation:
X * Y = 1305
Now use the first equation to substitute Y with 16 + X, in the second equation:
X (16 + X) = 1305
16 X + X^2 = 1305
X^2 + 16 X - 1305 = 0
Now use the quadratic formula to solve for X, and we get two possible answers: X = -45 or X = 29
So, since we are looking for whole numbers, we discard the negative answer, and keep X = 29
Then, the value of the other number "Y" is = 29 + 16 = 45

Find the least whole number that can replace ? To make the statement true
? ÷9>700
Answer:
6301.
Step-by-step explanation:
First we find the integer such that ? / 9 = 700.
? = 700 * 9 = 6300.
Therefore the least whole number for ? / 9 > 700 should be 6301.

Prove the statement using the ε, δ definition of a limit. lim x → 1 4 + 2x 3 = 2
Given ε > 0, we need δ ---Select--- such that if 0 < |x − 3| < δ, then 2 + 1 3 x − 3 ---Select--- . But 2 + 1 3 x − 3 < ε ⇔ 1 3 x − 1 < ε ⇔ 1 3 |x − 3| < ε ⇔ |x − 3| < ---Select--- . So if we choose δ = ---Select--- then 0 < |x − 3| < δ ⇒ 2 + 1 3 x − 3 < ε. Thus, lim x → 3 2 + 1 3 x = 3 by the definition of a limit.
You want to prove
[tex]\displaystyle\lim_{x\to1}\frac{4+2x}3=2[/tex]
By the definition of the limit, this means that for any [tex]\varepsilon>0[/tex], we can find [tex]\delta>0[/tex] such that
[tex]|x-1|<\delta\implies\left|\dfrac{4+2x}3-2\right|<\varepsilon[/tex].
In order to get the inequality we want, we need to have
[tex]\left|\dfrac{4+2x}3-2\right|=\left|\dfrac{2x-2}3\right|=\dfrac23|x-1|<\varepsilon\implies|x-1|<\dfrac{3\varepsilon}2[/tex]
so we can pick [tex]\delta=\frac{3\varepsilon}2[/tex].
So here's the proof: Let [tex]\varepsilon>0[/tex] be given, and let [tex]\delta=\frac{3\varepsilon}2[/tex]. Then
[tex]|x-1|<\delta=\dfrac{3\varepsilon}2[/tex]
[tex]\implies\dfrac23|x-1|<\varepsilon[/tex]
[tex]\implies\left|\dfrac{2x-2}3\right|=\left|\dfrac{2x+4}3-1\right|<\varepsilon[/tex]
as required.

Answer: [tex](6+7\sqrt{3},0)\text{ and }(6-7\sqrt{3},0)[/tex] are the required points.
or (18.124,0) and ( -6.124,0) are the required points.
Step-by-step explanation:
Let (x,0) be the point on x -axis that are 14 units from the point (6,-7) .
Then by distance formula , we have
[tex]\sqrt{(x-6)^2+(0-(-7))^2}=14\ \ \ [\ \because distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}][/tex]
Taking square on both the sides , we get
[tex](x-6)^2+7^2=14^2\\\\\Rightarrow\ x^2+6^2-2(6)x+49=196\\\\\Rightarrow\ x^2+36-12x=147\\\\\Rightarrow\ x^2-12x=111\\\\\Rightarrow\ x^2-12x-111=0[/tex]
Using quadratic formula : [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\dfrac{12\pm\sqrt{(-12)^2-4(1)(-111)}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{144+444}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{588}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{2^2\times7^2\times3}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm14\sqrt{3}}{2}\\\\\Rightarrow\ x=6\pm7\sqrt{3}[/tex]
so, [tex](6+7\sqrt{3},0)\text{ and }(6-7\sqrt{3},0)[/tex] are the required points.
since [tex]\sqrt{3}=1.732[/tex]
so, [tex](6+7(1.732),0)\text{ and }(6-7(1.732),0)[/tex] are the required points.
i.e. (18.124,0) and ( -6.124,0) are the required points.
There are 40 nickels in a roll. If you have 150 rolls of nickels, how many nickels do you have?
You would have 6,000 nickels. Multiply 40 by 150
There are 6000 Nickels in 150 rolls of Nickle.
To find out the total number of nickels you have, you need to multiply the number of nickels in a single roll by the number of rolls.
Given that there are 40 nickels in a roll and you have 150 rolls..
So, the total number of nickels can be calculated as:
= 40 nickels/roll x 150 rolls
= 6000 nickels.
Therefore, you have 6000 nickels.

How to find measurement of degree?
Answer:
It's 30 degrees. YSX and QSL are verticals so they are equal. Then QSL AND MLP are corresponding so they are too equal. So then yeah.
Answer:
30°
Step-by-step explanation:
It’s important to note the angle relationships.
We have two parallel lines intersecting one line. This means that each of the angles formed by one line will be equal to the angles formed by the other.
Using this info, we can tell that XYZ and MLP are alternate exterior angles, since they are formed by two parallel lines.
Alternate exterior angles are equal: since we know XYZ is 30°, MLP must be 30°.

The average hourly wage of computer programmers with 2 years of experience has been $21.80.Because of high demand for computer programmers,it is believed there has been a significant increase in the average wage of computer programmers.To test whether or not there has been an increase,the correct hypotheses to be tested area. H0: μ < 21.80 Ha: μ >= 21.80b. H0: μ = 21.80 Ha: μ ≠ 21.80c. H0: μ > 21.80 Ha: μ =< 21.80d. H0: μ <= 21.80 Ha: μ > 21.80
Answer:
d. H0: μ <= 21.80 Ha: μ > 21.80
Step-by-step explanation:
We set the null hypothesis as what is already given . We are already informed that the average wage is equal to μ <= 21.80 against the claim that is required. It is required to test whether the average wage of the computer programmers is greater than μ > 21.80
So option d is the best answer.
Hypotheses testing is done using an observation and a claim. The observation is set as a null hypothesis and claim is set as an alternative hypothesis. The null and alternative hypotheses must be chosen wisely to get the correct results.
The critical region is dependent on the claim set.
tristan wants to build a square garden in his backyard. if the garden is going to be 64 ft squared how many feet of material will he need for the perimeter of the garden?
Answer:
32 ft
Step-by-step explanation:
First Tristan must determine the length of one side of his square garden. Sine A = x^2, where x is the length of one side, and since 64 ft^2 = x^2, we can find the length x by taking the square root of both sides: 8 ft = x.
Now the length of the material enclosing the garden is the perimeter, P.
For a square, P = 4x.
Therefore, in this case, P = 4(8 ft) = 32 ft

A company recently replaced its 9-oz cup of yogurt with a 7-oz cup and reduced the suggested retail price from 87 cents to 75 cents. Was the price per ounce reduced by the same percent as the size of the cup? If not, find the price difference per ounce in terms of a percent.
Answer:
Question 1
Was the price per ounce reduced by the same percent as the size of the cup? No it's not the same
Question 2
If not, find the price difference per ounce in terms of a percent.
13.8%
Step-by-step explanation:
The first yoghurt cup size = 9 oz
The second and recent yoghurt cup size = 7 oz
The difference in ounces = 9 oz - 7 oz
= 2 oz
Converting this difference to percentage
= 2 oz/ 9 oz × 100%
= 22.222222222%
The percent reduction in cup size is approximately
22.2%.
The first retail price per ounce = 87 cents
The second and recent retail price per ounce =75 cents
The difference in prices = 87 cents - 75 cents
= 12 cents
Converting this difference to percentage
= 12 cents / 87 cents × 100%
= 13.793103448%
The percent reduction in yoghurt price per ounce is approximately
13.8%.
Question 1
Was the price per ounce reduced by the same percent as the size of the cup?
From the above calculation,
Percent reduction in price per ounce =
13.8%
Percent reduction in the size of the cup = 22.2%
13.8% ≠ 22.2%
Therefore, it is not the same
Question 2
If not, find the price difference per ounce in terms of a percent.
Therefore, the price difference per ounce in terms of percent is
13.793103448%.
Approximately ≈ 13.8%

Answer:
8.8km , 8810m , 8812m , 8.821km , 8.9km , 8901m
Step-by-step explanation:
1km = 1000m
Convert values in km to m by multiplying them by 1000
8.8km × 1000 = 8800m
8.821km × 1000 = 8821m
8.9km × 1000 = 8900m

ST = 7x
SU = 45
TU = 5x – 3
Find:
Each value
Computation:
SU = ST + TU
45 = 7x + 5x - 3

ST = 28 unit
TU = 5x – 3
TU = 5(4) – 3
TU = 17 units

First, use a chart or calculator to find the z-score for reach percentage.
P(Z > z) = 0.24
P(Z < z) = 1 − 0.24 = 0.76
z = 0.706
Next, use definition of z-score to find the value.
z = (x − μ) / σ
0.706 = (x − 5.2) / 0.5
x = 5.55
Repeat for the other percentage.
P(Z < z) = 0.15
z = -1.036
z = (x − μ) / σ
-1.036 = (x − 5.2) / 0.5
x = 4.68
