Step-by-step explanation:Step-by-step explanation:    Surface area of triangular prism = 2A + PH.

                                               Lateral surface of a triangular prism = Length × (a + b + c)  

i hope it helps u :-)

Answer:

Step-by-step explanation:

Area of triangle = bh/2

A = 4*5/2

A = 10 cm sq

A of 2 triangles = 10*2 = 20 cm sq

Now, Area of 1 rectangle = lb --> 10*5 = 50 cm sq

A of 3 rectangles = 50*3 = 150 cm sq

Now, LSA = 150 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 20 + 150 = 170 cm sq

Hope it helped. Pls mark me the BRAINLIEST! Don't fool pls

Answer:

  y = 32 -2x

Step-by-step explanation:

You want an equation for the remaining community service Yuson must complete after x days if she does 2 hours per day and is half done after 8 days.

Yuson has completed (2 hr/day)·(8 day) = 16 hr of community service after 8 days. This is half the total required, so the initial amount required must be 2·16 = 32 hours.

After x days, 2x hours have been completed, reducing the amount remaining. Thus the amount remaining is ...

  y = 32 -2x . . . . . hours left after x days

Answer:

x ≤2

Step-by-step explanation:

There is a closed circle at 2 and the line goes to the left.

The line going to the left means less than.  The closed circle means equal to

x ≤2

Answer:

x < 2

Step-by-step explanation:

Since 2 is a positive, larger than a negative the symbol is <

And since the it is a closed circle you have to underline the < to <

Answer:

Radius = 6

Area= 113

Step-by-step explanation:

If you want to find the radius of a circle divide its diameter by 2.

If you want to find the diameter of a circle multiply its radius by 2.

To find an area of an circle do: Pi(Radius to the power of 2)

Answer: 2.55

Step-by-step explanation:

To find the diameter you divide the circumference by pi (3.14).

The formula is d=c/π

8/3.14 is 2.547... and when rounded would be 2.55 or 2.6 if rounded.

Hope that helps!

Answer:6.3×(15÷3+6.8)-28.09

Step-by-step explanation: Hello!

6.3×15÷3±6.8-28.09

You should probably use addition instead of subtraction so let's try:

First try the expression 6.3×15÷3+6.8-28.09

You have to make a set of parentheses.  You should probably not include 6.3 in the parentheses so you can multiply whatever is in the parentheses by 6.3.  You should also probably not include -28.09 in the parentheses because you will make a negative number in the parentheses that won't be able to be made positive.  Try:

6.3×(15÷3+6.8)-28.09

6.3(5 + 6.8)-28.09

6.3(11.8)-28.09

74.34-28.09

=46.25

This is correct!

Answer:

Step-by-step explanation:

4^-5/3

1/(4^5/3)

1/(5sqrt(4^3)

I'm pretty sure?

Answer:

The equivalent ratios are: (1, 2), (2, 4), and (3, 6)

The graph can be plotted on a coordinate grid as shown in the diagram attached below.

Recall:

Ratio between two quantities, x and y, can be represented by the equation, y = kx, where k is the constant of proportionality.

k = y/x

Let x = number of books

y = cost (dollars)

Using any of the ordered pairs from the table, say, (7, 14), find k:

k = y/x = 14/7 = 2

Write the equation by plugging in the value of k into y = kx

y = 2x

Using the equation, y = 2x, find the equivalent ratios when x = 1, x = 2, and x = 3:

When x = 1:

y = 2(1) = 2 --> (1, 2)

When x = 2:

y = 2(2) = 4 ---> (2, 4)

When x = 3:

y = 2(3) = 6 ---> (3, 6)

The graph for the three equivalent ratios, (1, 2), (2, 4), and (3, 6) can be plotted on a coordinate grid as shown in the diagram attached below.

Answer: 12) 58.8%

13) 320%

14) 74.499%

15) 68.1%

Step-by-step explanation: To make a decimal a percentage, you need to multiply the decimal value by 100, like 0.499 as a percentage would be 49.9%, because I multiplied it by 100. Or, you could just move the decimal point 2 steps to the right.

Answer: X =24

Step-by-step explanation:

since the variable is multiplied to the fraction you have to do the opposite of multiplication to both sides.

[tex]\frac{1}{2}[/tex]÷[tex]\frac{1}{2}[/tex]=12÷[tex]\frac{1}{2}[/tex]

Do the keep change flip them simplify

x=12×2

x=24

Answer:13

Step-by-step explanation:

(y-7)²=36

Us PENDAS (Please Excuse My Dear Aunt Sally)

-7x-7=49

(y+49)=36

y=49-36

y=13

Hope this helps! Good luck!

Answer:

Step-by-step explanation:

√(y - 7)^2 = √36

y - 7 = +-6

----------------

y - 7 = 6

y = 13

-----------------

y - 7 = -6

y = 1

---------------

Therefore, y = 13 or y = 1

------------------------------------

There is no answer for y = 1, so we choose y = 13.

Step-by-step explanation:

Answer: A - Robotics > Garden

Step-by-step explanation:

Hello! What you need to do is look at the decimals.  You can write down which clubs have smaller decimals, equal decimals, and greater decimals than other clubs.  You know that there is an equal probability for the Robotics Club and Zoology Club because 0.2 = 0.2

Robotics Club = Zoology Club

You also know that the Garden Club has the smallest percentage so:

Garden Club < Robotics Club = Zoology Club

And you also know that the technology club has the greatest percentage out of all of them so:

Garden Club < Robotics Club = Zoology Club < Technology Club

_<_ blank is less than blank, _>_ blank is more than blank, _=_ blank is equal to blank.  A way I was able to remember this is that a smaller crocodile eats a bigger crocodile.

Now use the information you know:

Garden Club < Robotics Club = Zoology Club < Technology Club to figure out the answer.

Look at the last answer.  You know the student is not more likely to join the Garden Club (0.1 or 10%) than the Robotics Club (0.2 or 20%) because the percentage of a student joining the garden club is smaller than the percentage of joining the Robotics Club.  The formula shown for that answer is correct with Garden < Robotics, but what the rest of the answer says is incorrect.

Look at the third answer.  You know that the student is not unlikely to join the Zoology Club (0.2 or 20%) than the Robotics Club (0.2 or 20%) because the probability of both is equal as shown in the formula previously made, Robotics Club = Zoology Club.

Look at the second answer.  The percentage of a student joining the robotics club (0.2 or 20%) is smaller than the percentage of a student joining the technology club (0.5 or 50%), so they are not equally likely.  The chance of a student joining the technology club is greater than the chance of a student joining the robotics club.  This answer is also not correct.

Look at the first answer.  The student is more likely to join the robotics club than the garden club because 0.2 (20%) is greater than 0.1 (10%).  The formula is also correct because Robotics > Garden, or Robotics is greater than the probability of a student joining the garden club.  The first answer is correct.
