Answer:
w > -1
Step-by-step explanation:
Hello There!
We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations
So we want to get rid of the 8 in 8w
8w is the same as 8 times w (multiplication)
The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8
-8/8 = - 1
8w/8=w
we're left with w > -1

Which expressions are equivalent to 64 Superscript 1? Check all that apply.
A) 4 cubed
B) 3 Superscript 4
C) 8 squared
D) 2 Superscript 8
E) 6 squared
F) 2 Superscript 6
Answer:
I believe it would be C, 8 squared.
Step-by-step explanation:
8 squared means to multiply 8 twice. Not by two, 8 times 8. If you do that, you will get 64. This means that 8 squared is equivalent to 64'1

C
Step-by-step explanation:
use the graph f(x)=-x^2+8x+20 to determine the values of m for which m= -x^2+8x+m=0 will have two positive roots
Answer:
first root -2 and the second is 10
Step-by-step explanation:
delta=b squared-4ac=64-4(-1)(20)=144>0
then we have 2 +roots
x1= -b+ radical delta/2a =-2
x2=-b - radical delta/2a=10
The value of m for which -x² +8x+m=0 to have two positive roots is m ≤ 0.

Make q the subject of the formula p = 2q2 .
Answer:
q = ± [tex]\sqrt{\frac{p}{2} }[/tex]
Step-by-step explanation:
Given
p = 2q² ( divide both sides by 2 )
[tex]\frac{p}{2}[/tex] = q² ( take the square root of both sides )
± [tex]\frac{p}{2}[/tex] = q
Answer:
q = +√p/2
Step-by-step explanation:
p = 2q²
divide both sides by 2 and root we get,
√p/2 = √2q²/2
√p/2 = q
q = +√p/2
Thus, q = +√p/2

Hope this helps!
Have a nice day <3
After changing the unit of 144 inches into yards the number equivalent to 144 inches is 4 yards. Hence option (a) is true.
Given that,
Change the number 144 inches into yards.
Used the concept of measurement unit which stated that,
A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.
Since we know that,
1 yards = 36 inches
1 inch = 1/36 yards
So, we can change the number 144 inches into yards,
1 inch = 1/36 yards
144 inches = 144/36 yards
= 4 yards
Therefore, 144 inches is equivalent to 4 inches.
Option (a) is true.

Ralph and Jody go to the shop to buy potato chips and candy bars.
Ralph buys 3 bags of potato chips and 4 candy bars. He spends
Jody buys 4 bags of potato chips and 2 candy bars. She spends $3.00.
Later Clancy joins Ralph and Jody and asks to buy one bag of potato chips and one candy bar from
them. They need to work out how much he should pay.
Ralph writes
3p+ 4b = 375
1. If p stands for the cost, in cents, of a bag of potato chips and b stands for the cost, in cents, of a
candy bar, what does the 375 in Ralph's equation mean?
Answer:
375 represents the amount Ralph paid for 3 bags of potato and 4 candy bars
Bag of potato = 45 cent
Candy = 60 cents
Step-by-step explanation:
375 represents the amount Ralph paid for 3 bags of potato and 4 candy bars
3p + 4b = 375 - - (1)
4p + 2b = 300 ---(2)
From (2)
4p = 300 - 2b
p = 75 - 0.5b
Put b = 75 - 0.5b
3(75 - 0.5b) + 4b = 375
225 - 1.5b + 4b = 375
225 + 2.5b = 375
2.5b = 375 - 225
2.5b = 150
b = 150 / 2.5
b = 60
3p + 4(60) = 375
3p + 240 = 375
3p = 375 - 240
3p = 135
p = 45
Bag of potato = 45 cent
Candy = 60 cents

Find the approximate area of the lake whose shape is overlaid on the grid below. Each
square of the grid represents one square mile. (3 points)
Answer:
7.5 square miles
Step-by-step explanation:
Begin by counting the number of squares that the lake completely or almost completely covers. There are six of these, as indicated by an X. Then find the squares which are about half covered by the lake. These are indicated by a Y. There are three of these. The remainder of the squares that contain some portion of the lake are less than half covered, so we will not count them.
Irregular Object
1 square = 1 sq. mile
Each X counts as one square mile, and each Y counts as 0.5 (12) of a square mile.
(6 × 1) + (3 × 0.5) = 6 + 1.5 = 7.5
The area of the lake is about 7.5 square miles.

Write the equation in standard form for a circle that has a diameter with endpoints (8,0) and (-8,0)
Answer:
x²+y² = 64
Step-by-step explanation:
The standard form of writing the equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius of the circle
Given the diameter of the circle with endpoints (8,0) and (-8, 0)
d = √(x2-x1)²+(y2-y1)²
d = √(-8-8)²+(0-0)²
d = √(-16)²
d = √256
d = 16
radius r = 16/2
r = 8
The centre of the circle will be the midpoint of the coordinates
M = (8-8/2, 0+0/2)
M = (0/2, 0/2)
M = (0,0)
Hence the centre is at (0,0)
Get the required equation
Recall that (x-a)²+(y-b)² = r²
Substitute the centre and the radius
(x-0)²+(y-0)² = 8²
x²+y² = 64
This gives the required equation
