Answer:
50.137
Step-by-step explanation:
You can split the triangle into two triangles both with base 3 and height 12
The area of the two triangles is
[tex]2 * (1/2) * B * H\\B*H = 3* 12 = 36[/tex]
The area of a circle is [tex]\pi r^2[/tex]
so the area of the semi circle with r(adius) 3 is
[tex]\pi r^2/2\\9\pi/2[/tex]
[tex]9\pi/2 + 36 = 50.137[/tex]
Two window washers start at the heights shown. One is rising, the other is descending. How long does it take for the two window washers to reach the same height? Explain.
21 ft high
rising 8 in./s
50 ft high
descending 11 in./s
After t seconds, the height of the rising window washer is exactly
nothing feet, and the height of the descending window washer is exactly
nothing feet. Setting these expressions equal to each other and solving for t yields the exact value t
nothing. Rounding to one decimal place, the window washers reach the same height after about
nothing seconds.
(Simplify your answers.)
Answer: 18.32secs
Step-by-step explanation:
given data:
first washer
21 ft high
rising 8 in./s
second washer
50 ft high
descending 11 in./s
Solution:
initial height of first washer = 21 feet
1feet = 12inches
21 * 12 = 252inches
decending at a pace of 8inch/secs
= 252 + 8x
initial height of second washer
= 50 feet
= 50 * 12
= 600inches
descending at a pace of 11inch/secs
= 600 + 11x
At what time would they meet
252 + 8x = 600 + 11x
collect like terms
8x + 11x = 600 – 252
19x = 348
divide both sides by 19
19x/19 = 348/19
x = 18.32secs
Melanie had 3 pounds of dried fruit. She packed the dried fruit into bags of 3/8 pound each. How many bags of dry fruit does she pack?
Answer: 8 bags
Step-by-step explanation:
From the question, we are informed that Melanie had 3 pounds of dried fruit and that she packed the dried fruit into bags of 3/8 pound each.
For us to get the number of bags of dry fruit does she will pack, we have to divide 3 pounds by 3/8 pounds. This will be:
= 3 ÷ (3/8)
= 3 × (8/3)
= 8
Therefore, she will pack 8 bags of dried fruit.

5 less than 3.1 times a number n plz help me
Answer:
-2.1 i guess
Step-by-step explanation:3.1 minus 5 =-2.1
The required expression will be x = 3.1 n - 5
It is given that a number is 5 less than 3.1 times a number "n" .
We have to find the expression for the given statement.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.
Let's assume the number be x.
So ,
3.1 times of number n = 3.1 × n = 3.1 n
Let's subtract 5 from the above number, i.e.,
3.1 n - 5
and , the required expression will be ;
x = 3.1 n - 5
Thus , the required expression will be x = 3.1 n - 5

Which of the following graphs is the solution set of -10 < 3x - 4 < 8?
Answer:
Its the first one . A
Step-by-step explanation:
The solution set for the given inequality is {-1, 0, 1, 2, 3}. Therefore, option A is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -10<3x-4<8.
Now, -10<3x-4
Add 4 on both the sides of an inequality, we get
-6<3x
-2<x
Now, 3x-4<8
Add 4 on both the sides of an inequality, we get
3x<12
x<4
-2<x<4
Solution set is {-1, 0, 1, 2, 3}
Therefore, option A is the correct answer.

Find the value for x that makes the given equation true. - -4(3x – 7) + 5x = -2x + 8
Answer:
Okay this might be slightly confusing but I'll try to make it simple. x = -10
Step-by-step explanation:
-4 ( 3x - 7 ) + 5x = -2x + 8 1. get rid of parenthesis first. -4 times 3x = -12x and -4 times -7 is 28
-12x + 28 + 5x = -2x + 8 2. Combine any like terms on each side of the equation. -7x + 28 = -2x + 8 3. Get rid of the smallest x value by adding to both sides -7x
+7x +7x
28 = -2x + 8 4. subtract 8 from both sides to get rid of it. (you wanna get x alone)
-8 -8
20 = -2x 5. Divide both sides by -2 to get 1x (which is x)
/-2 /-2
x = -10
