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

Write your answer in standard form. (6x+7) (x-8)
a. 6x^2-24x-56
b. 6x^2+7x-56
c. 6x^2+21x+56
d. 6x^2-41x-56
(w+3)(w-3)
a. w^2+3w-3
b. w^2
c. w^2-9
d. w^2+w
Answer:
First one is d and second one is c
Step-by-step explanation:
(6x+7)(x-8)
(6x)(x) = 6x^2
(6x)(-8) = -48
(7)(x) = 7x
(7)(-8) = -56
Add all like terms together and you get choice d.
(w+3)(w-3)
(w)(w) = w^2
(w)(-3) = -3w
(3)(w) = 3w
(3)(-3) = -9
Add all like terms together and you get choice c
Answer:
(6x+7)(x-8)=6x^2-41x-56
Step-by-step explanation:
(6x+7)(x-8)
Apply FOIL method: (a+b)(c+d)=ac+ad+bc+bd= a=6x, b=7 c=x, d=-8=6xx+6x(-8)+7x+7(-8)
Apply minus & plus rules: =6xx-6(8x+7x-7)8
simplify: 6xx-6(8x+7x-7)8=6x^2-41x-56

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]

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.

Answer:
Yes
Step-by-step explanation:
5,0 is a solution to the graphed inequality as it lies on the edge of the shaded area. Because the line is solid rather than dotted/dashed this means that all answers on the line will be included in the solutions. This is a graph for an inequality with one of these symbols ≤ ≥.
