Answer:make sure the value of x is positive
-check the solution to ensure it is a rational number
Step-by-step explanation: .
When solving equations with square roots it is important,
to make sure the value of x is positive.check the solution to ensure it is a rational numberEquation with square root:When solving equations with square roots it is important to keep in mind;
The value of x must be greater than or equal to zero i.e. value of x should be positive.
Rational number is a number which can be express in p/q form where q can not be equal to zero. Therefore, value of x should be rational number.
If radical expression is present, isolate the radical on one side of the equation. Square both sides of the equation. Solve the new equation.

When mrs.Larkins went to her garden to pick tomatoes, 4 out of 20 were rotten. If mrs. Larkin picked 70 tomatoes, how many were rotten.
Answer: 14 tomatoes were rotten
Step-by-step explanation:
Total number of tomatoes picked by Mrs Larkin= 70
Fraction of tomatoes rotten =4/20
Number of tomatoes rotten = fraction of tomatoes rotten x Total number of tomatoes picked
= 4/20 x 70
=1/5 x70
=14

x=0, 1/2
Step-by-step explanation:
Answer:
x=0, x=1/2
Step-by-step explanation:
2x(x-1/2)=0
Use the zero factor Principle
x=0 or x-1/2=0
Solve x-1/2=0;
Add 1/2 to both sides;
x-1/2+1/2=0+1/2

Step-by-step explanation:
70 x 0.10 = 7
Answer:
10% of 70 is equivalent to 7.
Step-by-step explanation:
If 10% of something is 7, then 7 divided by 10% is equivalent to that number. [tex]7[/tex] / [tex]\frac{10}{100}[/tex] = [tex]7 * 10[/tex] = 70.
Find the total surface area of this cone.
Leave your answer in terms of .
15 cm
8cm
SA = [ ? ]cm2
Hint: Surface Area of a Cone = tre + B
Where e = slant height, and B = area of the base
Answer:
200π cm^2
Step-by-step explanation:
Sb = 8^2 π = 64π cm^2
a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm
Sl = 8x17xπ = 136 π cm^2

Answer:
A = 27.2 mm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 8 and h = 6.8 , then
A = 0.5 × 8 × 6.8 = 4 × 6.8 = 27.2 mm²

Answer:
$140.74
Step-by-step explanation:
Assuming this is a decaying exponential function, we can find a model for the depreciation in the form of v = a(b^t)
At t = 0, we get 5000 = a(b^0), which gives us a = 5000
At t = 1, we get 4000 = 5000b, such that b = 4/5
Now that our function is defined as v = 5000(4/5)^t, we can plug in t = 16 to solve for the value of the piano.
v = 5000(4/5)^16, which is approximately $140.74.

With shapes like these, you need to split it into parts you can find the area for and add it together at the end.
Let's take the rectangle out of the two other triangles first,
15x8=120. First area solved.
Now remember, you find areas of triangles by bxh/2. Let's do the one on the side first. 9x8=72. 72/2=36. Second area solved.
The final triangle has a height of 7 m, and it's parallel to the 15 m length from before. 7x15=105, 105/2=52.5. Last area found.
Now let's add them all together. (120+36+52.5)=208.5.

Although you love to watch TV, you have made a goal to spend more time outdoors. You decide that you will spend 222 times as many hours outdoors as you spend watching TV. Write an equation for the number of hours you will spend outdoors, ooo, when you spend ttt hours watching TV.
Answer:
the equation that should be required is 0 = 2t
Step-by-step explanation:
Let us assume the hours of television be t
And, for hours outdoor be o
As the hours outdoors would be twice the hours of television so the equation is
0 = 2t
Therefore the equation that should be required is 0 = 2t
The same is relevant
Answer:
o = 2t
Step-by-step explanation:
You will spend 2 times as many hours outdoors as you spend watching TV. The number of hours you spend outdoors depends on t, the number of hours you spend watching TV.
To find the number of hours you will spend outdoors, o, you can use the equation o = 2t
Remember, you want to find the number of hours you will spend outdoors if you spend 4 hours watching TV and 8 hours watching TV.
8 = 2 x 4
16 = 2 x 8
Now we can turn the values from the equation into ordered pairs in the form (x , y).
The ordered pairs are (4 , 8) and (8 , 16).
What is the equation to the line that goes through the point
(-3, 4) and is perpendicular to the line
y=-x+1
Step-by-step explanation:
perpendicular slope is negative reciprocal. -1/-1 = 1
y - 4 = x +3
y = x + 7

A cake recipe says to bake the cake until the center is 180°F. then let the cake cool to 100°F. The table shows temperature readings for the cake.
a. Given a room temperature of 69°F, what is an
exponential model for this data set?
b. How long does it take the cake to cool to the desired
temperature?
Answer:
8.058655822 mins
Step-by-step explanation:
We have a table and to solve for this we might want to find the equation for this
This is a exponential function
To solve for this we need the rate of decay and the x intercept
We know the x intercept is 180 because in 0 mins the temp is 180
To solve for decay we need to know the temp of the cake after 1 min
to get the decay value we can do
125= 180 (x)^5
.69444444444 = x^5
0.929667185 = x
so the equation would be
180 (0.929667185)^x
if we tell this equation to equal 100
we get
100 = 180 (0.929667185)^x
.5556 = (0.929667185)^x
log .5556 = log 0.929667185 *x
log .5556 / log .929667185)
8.058655822= x
After 8.058655822 mins the cake will be 100 degrees
