Help? It says find the surface area of the triangular prism, and the base is an isosceles triangle
Answers
Given:
The figure and dimensions of the triangular prism.
The base is an isosceles triangle
To find:
The area of the triangular prism.
Solution:
The area of a triangle is:
[tex]A_1=\dfrac{1}{2}\times base\times height[/tex]
The base of the triangle is 24 cm and the height is 35 cm. So, the area of a triangular base (in sq. cm) is:
[tex]A_1=\dfrac{1}{2}\times 24\times 35[/tex]
[tex]A_1=12\times 35[/tex]
[tex]A_1=420[/tex]
The bases of the triangular prism are same. So, the area of the other triangular base is [tex]A_2=420[/tex] sq. cm.
The sides of the base triangle are 37 cm, 37 cm and 24 cm. So, the perimeter of the base triangle is:
[tex]P=37+37+24[/tex]
[tex]P=98[/tex]
Now, the curved surface area of the prism is:
[tex]A_3=P\times h[/tex]
Where, P is the base perimeter and h is the height of the prism.
The base perimeter of the triangular prism is 98 cm and the height is 48 cm. So, the curved surface area is:
[tex]A_3=98\times 48[/tex]
[tex]A_3=4704[/tex]
Now, the total area of the triangular prism is:
[tex]A=A_1+A_2+A_3[/tex]
[tex]A=420+420+4704[/tex]
[tex]A=5544[/tex]
Therefore, the area of the given triangular prism is 5544 sq. cm.

What is 67,795 rounded to the nearest thousand?
Answers
Explanation
Answer:
68 000
Step-by-step explanation:
When we round to the nearest thousand, we have to look which thousand is closer to the value. So in our case 67795 is 205 away from 68 000 and is 795 away from 67000. From this we know that 68 000 is closer, therefore if we round 67 795 to the nearest thousand we will get 68 000.
A student would like to estimate the proportion of students at his school who have lunch during period 4. To do so,
he selects a random sample of 40 students and finds that 30% of them have period 4 lunch. Later, he goes to the
guidance office and finds that of the 380 students at this school, 25% of them have period 4 lunch. Which of the
following properly describes the number, 25%?
sample
statistic
population
parameter
Yeah
Answers
Answer:
D
As we are getting the 25% from the whole population of 380 students, therefore this is a population proportion which is a parameter. Note that we get parameter from population and statistic from the sample.
Step-by-step explanation:
The property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.
What are population and sample?It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
We have:
Number of samples = 40
30% of them have period 4 lunch.
Total population = 380
25% of them have period 4 lunch.
Because we're collecting 25% from a population of 380 students, this is a population proportion that may be used as a metric.
We collect parameters from the population and statistics from the sample.
Thus, the property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

What is length of line segment?The distance between any two points is the length of the line segment joining the points.
The formula for the distance, D, between two points whose coordinates are (x₁, y₁) and (x₂, y₂)

This is called the Distance Formula.
Given,
Coordinates of points Q (8, 2) and R (5, 7)
Length of QR = Distance between point Q and point R.
D = √((x2 – x1)² + (y2 – y1)²)
D = √((5 - 8)² + (7 - 2)²)
D = √(-3² + 5²)
D = √9 + 25
D = √34

A health club charges a $25 one-time sign-up fee and a monthly membership fee of $44 per month. Find the rate of change.
Answers
Answer:
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 milesStep-by-step explanation:
The rate of change is 5.
What is rate of change?The rate of change of anything is how rapidly it changes over time (ROC).
You must first create the equation
y = mx + b,
where m represents the monthly price and b represents the one-time cost. Months are represented by the number x.
We replace 240 for y and solve for x to find the total number of months at a price of 240.
40 is subtracted from either side of 240 = 25x + 40.
200 = 25x
25 divided
8 months equals 8.
10 + 7r = 45
7r = 35
r = 5
Therefore, 5 is the rate of change.

Step-by-step explanation:
Parallel lines are lines that run across from each other but never intersect. For this to work, they must change at the same rate and have the same slant. This means parallel lines must have equal slopes; therefore, the slope of the parallel line is -4. It is also important to note that parallel lines must have different y-intercepts, or they would just be the same line.
