planes X and Y are perpendicular. Points A,E,F and G are points only in plane X. Points R and S are points in both planes X and Y. Lines EA and FG are parallel.
Based on this information, which pair of lines, together, could be perpendicular to RS? Select two options.
EA
ER
EF
FG
FS
Answer:
FG
Step-by-step explanation:
I did this on my computer
The pair of the line together, could be perpendicular to RS should be considered as the EA and FG.
What is perpendicular?In terms of elementary geometry, two geometric objects should be considered as the perpendicular when they intersect at a right angle. A line is treated to be perpendicular to another line in the case when the two lines intersect at a right angle.
Therefore, The pair of the line together, could be perpendicular to RS should be considered as the EA and FG.

Ricky just received a shipment of 600 CDs for his music store each CD cost $20 which of the following could be used to find the total amount you will pay for the CDs
Answer:
y = 20x
Step-by-step explanation:
y is the total amount that ricky will pay for the CDs.
x is the number of CDs that ricky bought.
so, in this case, if you replace the x by 600 :
y=20 x 600, witch means that the value of y is :
y = 12000 dollars.

A rectangle has an area of . Use factoring to find possible dimensions of the rectangle. Explain why you can use factoring to find the answer.
Answer:
The answer is below
Step-by-step explanation:
A rectangle has an area of x² + 7x + 12. Use factoring to find possible dimensions of the rectangle. Explain why you can use factoring to find the answer.
Solution:
A rectangle is a quadrilateral (ha four sides and four angles) in which opposite sides are parallel and equal to each other. All the four angles in a rectangle are 90° each.
The area of a rectangle is given by:
Area = length * width
Hence the area is the product of two sides.
Given that:
Area = x² + 7x + 12
Factoring to find both the length and width of the rectangle:
Area = x² + 7x + 12
Area = x² + 4x + 3x + 12
Area = x(x + 4) + 3(x + 4)
Area = (x + 4)(x + 3)
After factoring we can see that the area is the product of (x + 4) and (x + 3). Hence x + 4 is the length and x + 3 is the width.
Do you knows the product of a number and four is 1.08. He says the other factor must be 2.7 because there's only one digit before the decimal point in the product 1.08, so, there must be one digit before the decimal in the factor. Is drew correct
Answer:
Drew is incorrect
Step-by-step explanation:
Drew is incorrect
Let the number be x such that if the product of the number and four is 1.08 then
x * 4 = 1.08
Divide both sides by 4
x = 1.08/4
= 0.27
Drew is incorrect because the result (1.08) has 2 decimal places and not once as deduced by him hence the number of digits before the decimal point for the numbers being multiplied must be 2.

in a class of 32 students the mean height of the 14 boys is 1.56 meters and the mean height of all 32 students is 1.151 meters. work out the mean height of girls
Answer: Hence, Mean height of the girls is: 1.48
Step-by-step explanation: It is given that:
in a class of 32 students .
the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.
Since there are 14 boys in a class.
So, number of girls is equal to (32-14)=18.
The mean height of 14 boys is 1.56.
Hence the sum of height of 14 boys is= 1.56×14=21.84
Similarly mean height of 32 students is 1.515.
Hence, sum of height of 32 students=1.515×32=48.48.
Let x denote the mean height of 18 girls.
Hence, sum of height of 18 girls is: 18 x.
Now,
18x+21.84=48.48
( since sum of height of girls and boys is equal to the sum of height of all the students)
so, 18x=48.48-21.84
18 x=26.64
Hence, x=1.48
Hence, Mean height of the girls is: 1.48

Answer:
x = 3Step-by-step explanation:
Based on similar triangle;
14/49 = x+5/9x+1
Cross multiply
49(x+5) = 14(9x+1)
49x + 245 = 126x + 14
49x - 126x = 14 - 245
-77x = -231
x = -231/-77
x = 3
Hence the value of x is 3
