Answer:
6.1
Step-by-step explanation:
Surface area of the room = 2(lw + hl + hw)
Where,
l = length = 7 m
w = width = 4 m
h = height = 3 m
Surface area of the room = 2(lw + hl + hw)
= 2(7*4 + 3*7 + 3*4)
= 2(28 + 21 + 12)
= 2(61)
= 122 m²
A 4-L can of paint covers 40 m²
Number of 4-L can of paint needed for 1 coat = 122 m² / 40 m²
= 3.05 4-L can of paint
The walls need 2 coats of paint
Number of 4-L can of paint needed for 2 coats = Number of 4-L can of paint needed for 1 coat × 2
= 3.05 × 2
= 6.1 4-L can of paint

The base of a right rectangular prism has an area of 173.6 square centimeters and a height of 9 centimeters. What is the volume, in cubic centimeters, of the right rectangular prism?
Bonus: Find the volume of the shape below!
Answer:
hope this helps
Step-by-step explanation:
We are given the an area of
173.6 cm
and a height of 9 cm.
We also know that the formula for area is lw, meaning we can substitute the area for lw
in the volume formula.
Now let's plug in what we know into the formula and solve for the volume:
V=(173.6 cm2)(9 c)=1562.4 cm3 The volume of the rectangular prism is
1562.4 cm3
.

What is the value of x in this diagram? fo 1040 (x+10) 0 DO 43
Answer:
option (B) 33 is right answer
Answer:
x = 33Step-by-step explanation:
According to Supplementary Angle sum,
104° + x + x + 10° = 180°
=> 2x + 114 = 180
=> 2x = 180 - 114
=> 2x = 66
[tex] = > x = \frac{66}{2} [/tex]
=> x = 33 (Ans)

Answer:
64 left handed girls
25 left handed boys
89 total left handed students
Step-by-step explanation:
Multiply 320 x 0.2
Multiply 250 x 0.1
You can think of it this way, 0.2 is 2/10 and 0.1 is 1/10 so take 20 percent of 320 and 10 percent of 250
Add them up for your answer 64 + 25 = 89
Which of the following is a factor of
X^2
- 2x + 15
Select one
X-5
X+3
None of the above
X-3
Answer:
both (x - 5) and (x - 3) are factors of x^2 - 2x + 15
Step-by-step explanation:
Please write this all on one line: x^2 - 2x + 15.
Recognize that 3*5 = 15. Possible factors of x^2 - 2x + 15 are thus (x - 5) and (x + 3). Multiplying these together results in x^2 - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2 - 2x + 15.
f(x) = x² - 2x + 15
Solution:This function f(x) will have the negative "discriminant" in root ; thus forming complex roots
So this function has no rational roots

How can you write 200.000 using a whole number and a power
Answer:
2 x 10^5
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.
Question Explanation:
In other words you can write 200,00 using a whole number and a power 10 using scientific notation!
In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.
Solution:
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.

Acellus Find the value of x. Round to the nearest tenth. 33° 6 x = [?] PLEASE HELP DONT PUT RANDOM STUFF GETTING REPORTED
Answer:
3.27
Step-by-step explanation:
Let us assume that the values are the side of a right triangle where;
Hypotenuse = 6 (longest)
Angle of elevation = 33 degrees
Required
x = opposite side
Using the trig identity
Sin theta = opp/hyp
Sin 33 = x/6
x = 6sin33
x = 6(0.5446)
x = 3.27
Hence the value of x is 3.27
Note that the values of the sides are assumed.
You take a math quiz that has 25 regular points and 5 bonus points. You get a score of 20, which includes 2 bonus points. Let x represent the score you would have had without the bonus points, Which equation represents this situation?
A. x + 2 = 25 B. x + 20 = 25 C. x + 2 = 20
Answer:
c
Step-by-step explanation:
you score is 20, including bonus points. x=scor without bonus. that means that your normal score plus the bonus equals 20. so x +2=20

Answer:
(13/2)^27
Step-by-step explanation:
First note that ( )^0 = 1, so we need not bother with the last term.
Next, note that
(2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).
Finally, we must cube this last result. We get: (2/13)^(-9*3) = (2/13^(-27)
or
(13/2)^27
Note: we're "evaluating" an algebraic expression here, not "solving it," since there is no equation here.
Written as a simplified polynomial in standard form, what is the result when
(3x – 2)2 is subtracted from 9?
Answer:
-9x^2 + 12x + 5
Step-by-step explanation:
I'm assuming you meant (3x – 2)^2. The " ^ " indicates exponentiation and is required. We then have:
9 - (3x – 2)^2, which, when expanded, is
9 - (9x^2 -12x + 4), or:
-9x^2 + 12x + 5

Find the measure of the third side of each triangle.
Answer:
2x - 2y
Step-by-step explanation:
P = 7x + 2y
P =a + b + c
