Answer:
x = 400Step-by-step explanation:
100 more than 365 is equal to 65more then
we can solve with an equation
100 + 365 = 65 + x
100 + 365 - 65 = x
465 - 65 = x
400 = x
------------
check
100 + 365 = 65 + 400
465 = 465

Classify the triangle by its sides and angles. Explain your reasoning.
The triangle that has been shown is a scalene obtuse triangle.
What is a scalene obtuse angle triangle?
A triangle called a scalene triangle has three sides that are all different lengths. In other words, a scalene triangle has three different angles and no two of its sides have the same length.
A triangle with one obtuse angle is referred to as an obtuse triangle. Any angle that is greater than 90 degrees but less than 180 degrees is referred to as an obtuse angle.
Thus we have a scalene obtuse triangle.

Answer:
8/9 OR 32/36, depending on whether or not you need it simplified.
Step-by-step explanation:
We know one yard has 36 inches. Since Dennis buys 32, we'll simply put that over 36 to find our fraction. You'll then get 32/36, and the most simplified form of that is 8/9.

In Mr. Romeo's class, a student must work on i-Ready for at least 4 hours per month to receive a grade of 100. Last month Sophia received a math grade of 100. Which inequality represents the number of hours Sophia spent working on i-Ready last month, where h represents the number of hours? (PLEASE HELP MEE!! GIVING 10 POINTS!)
A. h≥4
B. h>100
C. h≤100
D. h<4
The inequality that represents the number of hours Sophia spent working on i-Ready last month is h ≥ 4.
Option A is the correct answer.
We have,
The problem states that a student must work on i-Ready for at least 4 hours per month to receive a grade of 100.
Since Sophia received a math grade of 100, it means that she has met the requirement of working on i-Ready for at least 4 hours in the last month.
And,
The symbol "≥" means "greater than or equal to," indicating that Sophia worked for at least 4 hours.
Therefore,
The inequality that represents the number of hours Sophia spent working on i-Ready last month is h ≥ 4.

the sum of the first 10 terms of an AP is four times the sum of the first 5 terms then the ratio of the first term to the common difference is
Answer:
The ratio of the first term to the common difference is 1 : 2
Step-by-step explanation:
The rule of the sum of the AP is
\(S_{n}=\frac{n}{2}[2a+(n-1)d]\) , where
a is the first number
d is the common difference
n is the position of the number
∵ \(S_{10}\) = 4 × \(S_{5}\) ⇒ (1)
→ Find \(S_{10}\) and \(S_{5}\)
∵ In \(S_{10}\) n = 10
∴ \(S_{10}=\frac{10}{2}[2a+(10-1)d]\)
∴ \(S_{10}=5[2a+9d]\)
∴ \(S_{10}\) = 10a + 45d ⇒ (2)
∵ In \(S_{5}\) n = 5
∴ \(S_{5}=\frac{5}{2}[2a+(5-1)d]\)
∴ \(S_{5}=2.5[2a+4d]\)
∴ \(S_{5}\) = 5a + 10d ⇒ (3)
→ Substitute (2) and (3) in (1)
∵ 10a + 45d = 4[5a + 10d]
∴ 10a +45d = 20a + 40d
→ Subtract 40d from both sides
∴ 10a + 45d - 40d = 20a + 40d - 40d
∴ 10a + 5d = 20a
→ Subtract 10a from both sides
∴ 10a - 10a + 5d = 20a - 10a
∴ 5d = 10a
→ Divide both sides by 5
∴ d = 2a
→ That means d is twice a or a is half d
∴ a : d = 1 : 2
The ratio of the first term to the common difference is 1 : 2

Use the unit circle to evaluate the followingHow do I solve this ?
So we want to evaluate:
\(\tan (\frac{2\pi}{3})\)For this, we might convert 2pi/3 to degrees.
This, is to make the graph more understandable.
Remember that:
\(\pi=180\)So we could make the following ratio:
\(\begin{gathered} \pi=180 \\ \frac{2\pi}{3}=x \end{gathered}\)Solving for x:
\(\begin{gathered} x=\frac{\frac{2\pi}{3}\cdot180}{\pi} \\ \\ x=\frac{120\pi}{\pi}=120 \end{gathered}\)Therefore, x=120°. Now, we could graph:
So,
\(\tan (120)=\frac{\sin120}{\cos120}=\frac{\sin 60}{-\cos 60}=\frac{\frac{\sqrt[]{3}}{2}}{-\frac{1}{2}}=-\sqrt[]{3}\)Assuming that the heights of college women are normally distributed with mean 65 inches and standard deviation 3.5 inches, what percentage of women are shorter than 68.5 inches
Answer: the percentage of women that are shorter than 68.5 inches is 84.1%
Step-by-step explanation:
Given that;
mean μ = 65
standard deviation σ = 3.5
percentage of women are shorter than 68.5 inches = ?
P( x < 68.5 ) = P(( x-μ)/σ)
we substitute
⇒ ( 68.5-65)/3.5)
⇒ P(z < 1)
form standard normal table
P( x < 68.5 ) = P(z < 1) = 0.84134 ≈ 84.1%
Therefore, the percentage of women that are shorter than 68.5 inches is 84.1%

A company is painting the exterior walls of a warehouse. find the lateral surface are of the walls in square feet if the walls are 100 ft., 200 ft, and 30 ft
The lateral surface area of the walls of the warehouse is 18,000 sq ft.
Area is a measure of the size of a surface or the amount of space that a two-dimensional shape occupies. It is typically measured in square units, such as square feet or square meters. The area of a shape is calculated by multiplying the length and width of the shape together.
To find the lateral surface area of the walls of the warehouse, you need to find the combined area of all the exterior walls. To do this, you can use the formula for lateral surface area, which is:
Lateral Surface Area = 2 * (l * h + w * h)
where l is the length of the wall, w is the width of the wall, and h is the height of the wall.
Using this formula, we can find the lateral surface area of each wall and add them together to get the total lateral surface area:
Wall 1: Lateral Surface Area = 2 * (100 ft * 30 ft) = 6,000 sq ft
Wall 2: Lateral Surface Area = 2 * (200 ft * 30 ft) = 12,000 sq ft
Total Lateral Surface Area = 6,000 sq ft + 12,000 sq ft = 18,000 sq ft
