Here's the solution ~
[tex]\qquad \sf \dashrightarrow \:b(b + 12) = 0[/tex]
Here, we have two cases :
Case 1[tex]\qquad \sf \dashrightarrow \:b = 0[/tex]
Case 2[tex]\qquad \sf \dashrightarrow \:b + 12 = 0[/tex]

A wall is 3600 sq ft.
A gallon of paint covers 600 sq ft.
Complete the conversion factor: 1 gallon / ? sq ft
Answer:
1 gallon / 600 sq ft
Step-by-step explanation:
As we can see, we are given that 600 sq ft uses one gallon to cover, therefore one gallon covers 600 sq ft (just vice versa of what's given).

The Length Of A Room is two time its breadth and breadth is two time its height If The volume of room is 512m2 what is the cost of plastering its wall at rs 5.50 per m2
Answer:
Rs 2464
Step-by-step explanation:
Given:
The length of a room is 2 times its breadth and breadth is 2 times its height. The volume of the room is 512 cubic metre.To find:
The cost of plastering it's wall at Rs 5.50 per square metre.Solution : A/C to given data;
[tex]Length = 2 * Breadth\\L = 2 * B[/tex]---> (1) and [tex]Breadth = 2 * Height\\B = 2 * H[/tex]----> (2)
A/C to given data let, structure of room is cuboidal.
Now, we have to find out the height of the room, so we use formula of volume of the cuboid.
[tex]Volume of the room = L * B * H[from given data, and eq. {1} and eq. {2}][/tex]
[tex]512 = 2B * 2H * H[/tex]
[tex]512 = 2 * 2H * 2H * H[/tex]
[tex]512 = 4H * 2H^{2}[/tex]
[tex]512 = 8H^{3}[/tex]
[tex]H^{3} = \frac{512}{8}[/tex]
[tex]H^{3} = 64[/tex]
[tex]H = \sqrt[3]{64}[/tex]
[tex]H = 4 m[/tex]
[tex]Now, put\\ value\\ of \\H \\in \\eq. {2}[/tex]
[tex]B = 2 * H[/tex]
[tex]B = 2 * 4[/tex]
[tex]B = 8 m[/tex]
[tex]\\[/tex]Now, put value of B in eq. {1}
[tex]L = 2 * B[/tex]
[tex]L = 2 * 8[/tex]
[tex]L = 16 m[/tex]
Now, we have to find out area of the room, so we use formula of total surface area of cuboid.
[tex]Area of the room = 2*L*B + 2*L*H + 2*H*B[/tex]
[tex]Area of the room = 2 * 16 * 8 + 2 * 16 * 4 + 2 * 4 * 8[/tex]
[tex]Area of the room = 32 * 8 + 32 * 4 + 8 * 8[/tex]
[tex]Area of the room = 256 + 128 + 64[/tex]
[tex]Area of the room = 384 + 64[/tex]
[tex]Area of the room = 448 m^{2}[/tex]
Now, to find out room wall plastering cost
[tex]Room wall plastering cost = Area of the room * cost of plastering per ^{2}[/tex]
[tex]Room wall plastering cost = 448 * 5.50[/tex]
[tex]Room wall plastering cost = Rs 2464[/tex]
[tex]ence, the room wall plastering cost is Rs 2464.[/tex]
Antonio weighs four pounds more than twice his brother weight. If Antonio weighs 97 pounds, how much does his brother weigh? Write and solve equation.
Answer:
The bother's weight is 46.5 lb.

Antonio's weight is 97 lb.
2b + 4 = 97
2b = 93
b = 46.5 lb
Answer: The bother's weight is 46.5 lb.

juan rolls a fair number cube twice what is the probability that he will roll an odd number on the first roll and an even number in second
Answer:
1/4
Step-by-step explanation:
[tex]\mathsf{Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ outcomes}}[/tex]
Assuming the number cube has faces number 1 through 6, the probability of rolling any of the number is 1/6.
Therefore,
P(odd number) = P(1) or P(3) or P(5)
= 1/6 + 1/6 + 1/6
= 3/6
= 1/2
Similarly,
P(even number) = P(2) or P(4) or P(6)
= 1/6 + 1/6 + 1/6
= 3/6
= 1/2
⇒ P(odd) AND P(even) = 1/2 × 1/2 = 1/4

find the rule to complete the pyramid.
Answer:
add two side by side values
Step-by-step explanation:
there are 5 values at the base of the pyramid.
4, 6, 3, 7 and 2
let's look at 6 and 3 first. when you add them together, you will get 9, which make up the upper layer of the pyramid. we can also support this statement when you add 7 with 2, which is also 9. so when you take 4 and add with 6, you will get 10, when you add 3 and 7, you will get 10.
now, let's see the second bottom layer. we get the answers as 10 in both blanks. so, add 10 with 9 and you will get 19, repeat with the other. so, the third layer will be 19, 19 and 19. to make the third layer complete, add 19 with 19, which will be 38. so, the fourth layer will be 38 and 38. add 38 with 38 and you will get 76 at the top of the pyramid.

Maria has 25 dollars. She has to buy a gallon of milk which costs $3.50. She wants to spend the rest of her money on cereal. If each box of cereal costs $4.50, how many can she purchase?
Step-by-step explanation:
total money she has = $25
she bought a gallon of milk for $3.50
amount remaining = 25-3.50 = $21.50
number of cereal she can buy with the remaining amount =21.50/4.50 = 4.77 boxes
she can buy 5 boxes (approximately)

When spinning a penny, Claire believes the proportion of times the penny lands on heads is higher than 0.5. She spins a penny 50 times and it lands on heads 32 times. The P-value for the test of the hypotheses, H 0: p = 0.5, and H alpha: p greater-than 0.5, is 0.02, What is the correct interpretation of this value?
It depends on what the level of significance (alpha) is.
Since alpha is not stated, I'll assume that alpha = 0.05 by default.
Because the p-value is smaller than alpha, we reject the null hypothesis.
Therefore, we conclude that the alternative hypothesis is correct and the proportion of heads is greater than 0.5

~lenvy~
Answer/Step-by-step explanation:
Base on the given we are..
Solving for x:
Solve:
X + 2x + 8 = X = 10 + 6 {x+2x= 3x}
3x + 8 = 10 + 6 {10+6=16}
3x + 8-8=16-8 {16-8=8}
3x = 8 {divide both sides by same term}
3x/3 = 8/3
Therefore,
x = 8/3
Decimal form = 2.66666666667

Which school has the greater number of girls and by how many?
You must show your working.
490 x 2/5 = 980/5 = 196 girls at Garland

Bowood has more girls:
675-196 = 479 more
three subtracted from 5 x a number is -128. what is that number
A) translate the statement above into an equation that you can solve to answer this question.
do not solve it yet use x as your variable.
the equation is :
B)solve your equation [A} for x
answer for x
5-3x=-128
LHS = RHS
(5 - 3) x A = -128
( 2 ) x A = -128
2A / 2 = -128 / 2
A = -64
the line y=ax-1 is parallel to the line by-(a+1)x=2. These two lines have the same distance to the origin. find a and b
By using the parallel condition and the fact that the distance to the origin is the same, we will see that a = 1 and b = 2.
How to find the values of a and b?First, remember that two lines are parallel if have the same slope and different y-intercept.
In this case, we know that
y = a*x - 1
b*y - (a + 1)*x = 2
Are parallel, if we write both of them in the slope-intercept form, we get:
y = a*x - 1
y = (a + 1)*x/b + 2/b
Note that because both of the lines are parallel, the slopes must be equal, then we have that:
(a + 1)/b = a
Then if we know that the distance of both lines to the origin is the same, we have that:
|-1/(√(a^2 + 1))| = | (2/b)/(√(((a + 1)/b)^2 + 1))|
Because the slopes are equal the denominators are equal, this means that:
|-1| = |2/b|
And the y-intercepts must be different, this means that:
b = 2
now we can solve:
(a + 1)/b = a
(a + 1)/2 = a
a + 1 = 2a
1 = 2a - a = a
a = 1 and b = 2.
