Step-by-step explanation:
In the EXPLORE online library, the ratio of the number of novels to that of dictionaries is 2:3 and the total number of novels is 624. If Joe buys more novels and the ratio becomes 7:3, then how many novels have been bought in total?
Using a system of equations, it is found that 1530 more novels have been bought in total.
For the system, we have that:
x is the number of novels.y is the number of dictionaries.The ratio of the number of novels to that of dictionaries is 2:3, hence:
[tex]\frac{x}{y} = \frac{2}{3}[/tex]
[tex]3x = 2y[/tex]
[tex]y = \frac{3x}{2}[/tex]
Total number of novels is 624, hence:
[tex]x = 624[/tex]
[tex]y = \frac{3}{2} \times 624 = 936[/tex]
Buys z more novels, and the ratio becomes [tex]\frac{7}{3}[/tex], hence:
[tex]\frac{624 + z}{923} = \frac{7}{3}[/tex]
[tex]1872 + 3z = 6461[/tex]
[tex]z = \frac{6461 - 1872}{3}[/tex]
[tex]z = 1530[/tex]
1530 more novels have been bought in total.

How much force is required to accelerate a 4 kg mass at 6 m/s2
Answer:
is it 24 N?
as we know ....
force=mass * acceleration
force=4kg*6m/s2
hence force is 24N
The required Force = 24 N
What is Force?The push or pull on an object with mass causes it to change its velocity.
Given that a body of 4 kg mass is accelerated at 6 m/s²
Force = ma
where m = mass and a = acceleration
F = 6*4 = 24 N
Hence, the Force required = 24 N

If a submarine dives 378 feet in 14 seconds, the average change in elevation is feet per second.
Answer:
27 feet per second.
Step-by-step explanation:
You already have your time unit in second and length measurement in feet so just divide the two 378/14=27 feet per second.
Answer:
-27 feet per second
Step-by-step explanation:
378 ÷ 14 = 27
because the submarine is going down, the sign has to be negative

Is ( - 1, 2) a solution of the system y > x and x + y > 0?
O No, because ( - 1, 2) is a solution to only one of these inequalities.
O Yes, because ( – 1, 2) is a solution to both inequalities.
O Yes, because ( - 1, 2) is the point of intersection of the two boundary lines of this system.
No, because ( – 1, 2) is not a solution to either inequality.
Answer:
Yes, because (-1,2) is a solution to both inequalities

if f(x) = 7(x-1) + 8 , what is rhe value of f(11) ?
Answer:
f(11)=78
Step-by-step explanation:
f(11)=7(11-1)+8
f(11)=77-7+8
f(11)=78
Answer:
F(11) = 78
Step-by-step explanation:
f(11) means that you would just have to replace “x” on the equation with 11 and then solve;
=> f(11) = 7(11 - 1) + 8
=> f(11) = 7(10) + 8
=> f(11) = 70 + 8
=> f(11) = 78
therefore the answe is 78

If x = 5-2√6, find the value of:
(i) x + 1/x
(ii) x² + 1/x²
Please solve ASAP
Answer:
x+(1/x) = 10 and x²+ (1/x²) = 98Step-by-step explanation:
Given that :
x = 5-2√6
1/x = 1/(5-2√6)
The denominator = 5-2√6
The Rationalising factor of 5-2√6 = 5+2√6
On Rationalising the denominator then
⇛ 1/x = [1/(5-2√6)]×[(5+2√6)/5+2√6)]
⇛ 1/x = (5+2√6)/[5-2√6)(5+2√6)]
⇛ 1/x = (5+2√6)/[5²-(2√6)²]
Since (a+b)(a-b) = a²-b²
Where ,
a = 5 and b = 2√6⇛1/x = (5+2√6)/(25-24)
⇛ 1/x = (5+2√6)/1
⇛ 1/x = 5+2√6
Now,
x +(1/x)
⇛ 5-2√6+5+2√6
⇛ 5+5
⇛ 10
Therefore, x+(1/x) = 10.
On squaring both sides then
⇛ [x+(1/x)]² = 10²
⇛ x²+2(x)(1/x)+(1/x)² =100
⇛ x²+2+(1/x)² = 100
⇛ x²+(1/x²) = 100-2
⇛ x²+(1/x²) = 98
Therefore, x²+(1/x²) = 98.

Answer:
Body surface area is calculated a) in m2 from weight and height.
Step-by-step explanation:
Basically the surface has to be in m2, because you have two dimensions when you multiply: e.g. when you have a lawn 10m x 10m, then you multiply 10 times 10, and meters times meters, so
