Answer:
57.1mm^2
Step-by-step explanation:
4*4=16
16/2=8mm^2 cross section
(4*3) + (4*3) + (5.7*3) = 41.1mm
8*2=16
41.1+16=57.1mm^2
The surface area of the prism is S = 57.1 mm²
What is the surface area of the prism?The surface area of the prism is calculated as
The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism
Surface Area of the prism = 2B + ph
The area of the triangular prism is A = ph + ( 1/2 ) bh
Given data ,
Let the area of the 2 triangles be T
Let the area of the 2 rectangles be R
Let the area of the third side be U
Now , the total surface area of the prism = T + R + U
where T = 2 x ( 1/2 ) ( 4 x 4 )
T = 16 mm²
R = 2 x ( 3 x 4 )
R = 24 mm²
And , U = 5.7 x 3
U = 17.1 mm²
Therefore , the total surface area of prism S = 16 mm² + 24 mm² + 17.1 mm²
S = 57.1 mm²
Hence , the surface area of prism is S = 57.1 mm²

Answers
Step-by-step explanation:
For every increase in the x-value by 1,
the y-value decreases by -2.
(From 3 to 1 and from 1 to -1)
Hence, slope of line k
= Rise/Run = (-2)/1 = -2. (A)
Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.
Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.
In this problem, two of the points are: (1,3) and (2,1).
Hence, applying the division:
[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]
The slope of the line is of -2, hence option A is correct.

A bike rental charges a flat fee of $500. As well as $0.05 every mile. If you spent$10 how many miles did you take the bike for? Write and solve an equation for this problem
Answers
Answer: 100 miles.
Step-by-step explanation:
Here , Flat fee = $ 5.00
Additional charge per mile = $ 0.05
Money spent = $ 10
Formula : Total Charge = Flat fee + (Number of miles ) x (Additional charge per mile)
Let x= Number of miles
Substitute values , we get
10 = 5 + 0.05x
⇒ 0.05x= 5
⇒ x = 100
Hence, I took bike for 100 miles.

A scatterplot has a positive, linear correlation. Which statement is true about the relationship between the x- and y-
values?
o As the x-values increase, the y-values tend to increase.
As the x-values increase, the y-values tend to decrease.
As the x-values decrease, the y-values tend to increase.
O As the x-values decrease, the y-values tend to vary randomly.
Answers
Answer:
Hence, option: A is the correct answer.
A. As the x-values increase, the y-values tend to increase.
Step-by-step explanation:
It is given that:
A scatterplot has a positive, linear correlation.
By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.
Hence, the statement which is true about the relationship between the x- and y-values is:
A. As the x-values increase, the y-values tend to increase.
Answer:
a: As the x-values increase, the y-values tend to increase.

Answer:
[tex]x=3[/tex]
Step-by-step explanation:
The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:
[tex]7 = 2x + 1[/tex]
Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:
[tex]6 = 2x[/tex]
The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:
[tex]3 = x[/tex]

A new set of apple airpods cost $250 calculate the new price if you got a 20% discount and the sales tax 8%
Answers
Answer:
$216
Step-by-step explanation
We know that we are paying 80% of the price of the airpods (20% off) so we can multiply the full price by 0.8.
250 * 0.8
This will give us 200.
Now, we need to add the sales tax which is 8%.
Simply multiply the 200 by 1.08 since we are paying the 200$ plus an extra 8% of the cost.
200 * 1.08 = $216

4.5 is 7.5% of what number?
Answers
Answer:
60
Step-by-step explanation:
The required number is 60.
What is percent?In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now the given expression is,
4.5 is 7.5%
Let x be the number.
Therefore, 7.5% of x is 4.5
⇒ 7.5% of x = 4.5
⇒ 7.5% * x = 4.5
⇒ 7.5/100* x = 4.5
⇒0.075 x = 4.5
Dividing both side by 0.075 we get,
x = 4.5 / 0.075
Solving we get,
x = 60
this is the required number.
Thus,the required number is 60.
