What Is The Surface Area Of This Triangular Pyramid?

Answers

Answer 1

Answer:

48.25

Step-by-step explanation:

This is because when finding the area of a triangle it is known as base times height then divide by 2 and since the base is a triangle, multiply 4.3 times 5 which is 21.5 and divide by 2 which is 10.75 and for the top since its also a triangle multply 5x5 which is 25 divide by 2 whicih is 12.5, but there is 3 of them so multiply by 3 and you get 37.5, then add 37.5+10.75 to get 48.25 cm^2

What is the equation of the line in slope-intercept form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

y = x + 6

Step-by-step explanation:

Line is passing through the points (0, 6) & (1, 7)

So, y-intercept (b) = 6

Slope (m) [tex] =\frac{(7 - 6)}{(1 - 0)} = \frac {1}{1} = 1[/tex]

Equation of line in slope-intercept form is given as:

y = mx + b

Plugging the values of m and b in the above equation, we find:

y = 1*x + 6

y = x + 6

Answer:

y-9=7(x+5)

Step-by-step explanation:

Point-Slope form is

[tex]y-y_{1} =m(x-x_{1} )[/tex]

where m equals the slope of the line and y1 and x1 represent the y and x coordinates of one of the points on that line.

First, let's find the slope (change in y divided by the change in x):

[tex]\frac{9-(-5)}{-5-(-7)} =\frac{14}{2} =7[/tex]

Now, let's choose any one of the two points, I'll pick (-5,9), but (-7, -5) also works.

Substitute in the y value (in this case 9) for y1 and substitute the x value (in this case -5) for x1

We can also substitute the slope, m which we know is 7.

y-9=7(x-(-5)

y-9=7(x+5)

Travis, Jessica, and Robin are collecting donations for the school band. Travis wants
to collect 20% more than Jessica, and Robin wants to collect 35% more than Travis.


If the students meet their goals and Travis collects $43, how much money did they collect
in all?

Answers

Answer:

their total collected is $135.45

Step-by-step explanation:

travis collect 20% more than Jessica

if travis collect $43 then

20% of 43

43 × 20 ÷ 100 = $8.6

Jessica collected $8.6 less than travis

$43 - $8.6 = $34.4

and Robin collect 35% more than travis

35% of 43

43 × 35 ÷ 100 = $15.05

therefore Robin collect $15.05 more than travis

$43 + $15.05 = $58.05

their total collected

Jessica collected $34.4

robin collected $58.05

travis collected $43

total

$34.4 + $58.05 + $43 = $135.45

What are the slope and the y-intercept of the linear function that is represented by the graph?

On a coordinate plane, a line goes through points (0, 3) and (4, 0).

Answers

The slope is the change in y over the change in x.

The first number in the parentheses is the x value, the second number is the y value.

Slope = (0-3) / (4-0)

Slope = -3/4

The y intercept is the y value when x is 0.

The given point (0,3) has x as 0, so the y intercept would be 3

Answers: slope = -3/4, y intercept = 3

Answer:

y intercept = 3 slope = -3/4

Hope this helps!
y=-1/2x+4.5
y=mx+b
first do rise over run so it goes down 3 units and to the right 6 units then you simplify 3/6 to the smallest fraction which would be 1/2 and since the line is going down horizontally the slope(1/2) would be negative then you simply see where the line crosses the y-axis and that is the "b"(4.5) for the equation now all you gotta do is plug in the numbers and you get
y=-1/2x+4.5

y = 3x - 2
m=
b=

Answers

Answer:

m is 3 since it's the slope and b is -2 since its the y-intercept

Step-by-step explanation:

the formula is y=mx+b so 3 is in the m spot and -2 is in the b spot.

Answer:  m = 3 , b = -2

Step-by-step explanation:

y = 3x - 2, we found out m and b by using the form y = mx + b, where m is the number in front of x.

Therefore we found out that m is 3, b is -2.
