Answer:
D) 2/3
Step-by-step explanation:
Constant of proportionality formula:
k = y/x
8/12 = 2/3
10/15 = 2/3
12/18 = 2/3
14/21 = 2/3
How many cubes with side lengths of 1/4 cm does it take to fill the prism?
8. 150 litres of water flows through a pipe in 6 minutes. Through the same pipe 200
litres of water flows in 8 minutes. Are the quantity of water flown and the time
taken are in proportion?
Answer:
Yes,they are in proportion
Step-by-step explanation:
We are told that 150 litres of water flows through a pipe in 6 minutes.
Thus means that the rate of flow = 150/6 = 25 litres/minutes
Now, we are also told that through the same pipe, 200 litres of water flows in 8 minutes. This means that the rate of flow = 200/8 = 25 litres/minutes
Now, the rate of flow is both instances is the same. Thus, we can say they are in proportion because;
Proportion of quantity in both instances = 200/150 = 4/3.
while that of time = 8/6 = 4/3
They have the same proportion
Enter an expression for the perimeter of the given figure. Simplify the expression.
10.2 in.x + 2 in.x + 2 in.x + 2 in.x + 2 in.10.2 in.
The perimeter of the figure is inches.
Answer:
4x + 28.4 in.
Step-by-step explanation:
perimeter = sum of lengths of sides
perimeter = x + 2 + x + 2 + x + 2 + x + 2 + 10.2 + 10.2
perimeter = 4x + 28.4

for the second question the options are: 71034, 71034000, 710.34 and 7013.4
Answer:
[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]
[tex]7.1034 * 10^3 = 7103.4[/tex]
Step-by-step explanation:
Solving (a):
[tex]0.0005[/tex]
Standard form is represented as:
[tex]a * 10^n[/tex] where [tex]1 \le a \le 10[/tex]
Move the decimal point to 5 and count the number of times the decimal point is moved forward (forward represents negative).
So:
[tex]a = 5[/tex]
[tex]n = -4[/tex]
Hence:
[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]
Solving (b):
[tex]7.1034 * 10^3[/tex]
Express [tex]10^3[/tex] as [tex]1000[/tex]
This gives:
[tex]7.1034 * 10^3 = 7.1034 * 1000[/tex]
[tex]7.1034 * 10^3 = 7103.4[/tex]

I dont think those are wuestiojs to be answered. Probably questions on how the equation is solved
Please show an explanation
Answer:
Step-by-step explanation:
1) Let x be the number of adults and y be the number of students
x + y = 8 --------------(I)
y = 8 -x
7.25x + 5.50y = 52.75 ----------------(II)
Substitute y = 8 -x in equation (II)
7.25x + 5.5*(8 - x) = 52.75
7.25x + 5.5*8 - x*5.5 = 52.75
7.25x + 44 - 5.5x = 52.75
7.25x - 5.5x + 44 = 52.75
1.75x + 44 = 52.75
1.75x = 52.75 - 44
1.75x = 8.75
x = 8.75/1.75
x = 5
Plugin x = 5 in equation 1
y = 8 - 5
y = 3
2) x = y + 24
x + y = 180 {Supplementary}
y + 24 + y = 180
2y + 24 = 180
2y = 180 - 24
2y = 156
y = 156/2
y = 78
x = 78 + 24 = 102

What is the slope of the line whose equation is 2x – 4y = 9?
a) 1
2
c) 2
d) 3
solotion
Answer:
m = 1/2
Step-by-step explanation:
The given equation of line is :
2x – 4y = 9 ..(1)
We need to find the slope of the line. The general equation of a line is given by :
y = mx + c ..(2)
Where
m is the slope of line
Equation (1) can be rearranged as follow :
-4y = 9-2x
4y = -9+2x
or
4y = 2x-9
Divide both sides by 4.
[tex]\dfrac{4y}{4} = \dfrac{2x}{4}-\dfrac{9}{4}\\\\y=\dfrac{1}{2}x+(\dfrac{-9}{4})[/tex] ..(3)
Now comparing equation (2) and (3) we get :
[tex]m=\dfrac{1}{2}[/tex]
So, the slope of the line is 1/2.

The manager of a large grocery store wants to inspect an incoming shipment of oranges to determine the
proportion of blemishes. One inspector, Mary, takes a random sample of 25 oranges, and another inspector, Pat,
takes a random sample of 50 oranges. Which of the following statements about variability of the sample proportion
is correct?
The variability of the proportion of blemishes for Mary's sample will be less than the variability of Pat's.
The variability of the proportion of blemishes for Mary's sample will be greater than the variability of Pat's.
The variability of the proportion of blemishes for Mary's sample will be the same as the variability of Pat's.
Since the two inspectors took two different samples, there is no way to compare the variability of the two samples.
Answer:
b
Step-by-step explanation:
The variability of the proportion of blemishes for Mary's sample will be greater than the variability of Pat's.

19. Elein and Naya wanted to meet between their

A. (7,-1.5)
(10,-4).
B. (-2,6)
Find the coordinates of Naya's house.
C. (0,0)
Answer:
[tex](-2,6)[/tex]
Step-by-step explanation:
Given
[tex]Elena = (10,-4)[/tex]
[tex]Midpoint = (4,1)[/tex]
Required
Determine the coordinates of Naya's
Midpoint is calculated as:
[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
In this case:
[tex](x_1,y_1) = (10,-4)[/tex]
[tex](x,y) = (4,1)[/tex]
So, we have:
[tex](4,1) = \frac{1}{2}(10+x_2,-4+y_2)[/tex]
Multiply through by 2
[tex]2 * (4,1) = \frac{1}{2}(10+x_2,-4+y_2) * 2[/tex]
[tex](8,2) = (10+x_2,-4+y_2)[/tex]
By comparison:
[tex]8 = 10 + x_2[/tex]
[tex]2 = -4 + y_2[/tex]
So:
[tex]8 = 10 + x_2[/tex]
[tex]x_2 = 8 - 10[/tex]
[tex]x_2 = -2[/tex]
[tex]2 = -4 + y_2[/tex]
[tex]y_2 =2+4[/tex]
[tex]y_2 =6[/tex]
So, the coordinate is: [tex](-2,6)[/tex]
