a flagpole 6.3m is driven 1.4m long into the ground .what fraction of the pole is above the ground
Answer:
4.9/6.3= .777777... , a simplified fraction form of this would be 7/9.
Step-by-step explanation:
Fraction 7/9 of the flagpole is above the ground
If a flagpole 6.3m long is driven 1.4m into the ground, then the fraction of the pole that is above the ground is 6.3m - 1.4m = 4.9m / 6.3m = 49/63 = 7/9.
To calculate the fraction of the pole that is above the ground, we need to subtract the length of the part of the pole that is driven into the ground from the total length of the pole. This gives us 4.9m. We then divide this length by the total length of the pole to get the fraction 7/9.
In other words, 7/9 of the flagpole is above the ground. This means that if we cut the flagpole into 9 equal pieces, 7 of those pieces would be above the ground and 2 of those pieces would be below the ground.

Evan was broke didn't he got his weekly allowance but because he has a hard time saving money he spent half his weekly allowance playing mini golf he just turned four dollars cleaning out his parents car if he now has 12 how much is his weekly allowance
Answer:
$16
Step-by-step explanation:
Let his weekly allowance = x
Amount spent playing golf = x / 2
Amount earned for cleaning car = $4
Final amount at hand = $12
Mathematically ;
x/2 + 4 = 12
x/2 = 12 - 4
x/2 = 8
x = 2 * 8
x = $16
Weekly allowance = $16

Answer:
First one = 120
Second one = 54
Third one = 64
Step-by-step explanation:
For the first figure a triangle must all add up to 180 degrees so just do
180-60 which gives you 120
For the second one it is the same 104+ 22 = 126 then you do 180-126 which gives you 54
For the 3rd figure that straight line is equal to 180 so you do 180-154 which gives you 26 and because the other angle is a right angle we know it adds up to 90. 90+26 = 116 then finally you do 180 - 116 which gives you 64.
Hope this helps.

Answer: 54
Step-by-step explanation:
The value of m ∠C will be;
⇒ m ∠C = 54°
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In △ABC , m ∠A= 37° and m ∠B = 89° .
Now,
Since, In △ABC ,
⇒ m ∠A= 37° and m ∠B = 89°
We know that;
⇒ m ∠A + m ∠B + m ∠C = 180°
⇒ 37° + 89° + m ∠C = 180°
⇒ 126° + m ∠C = 180°
⇒ m ∠C = 180° - 126°
⇒ m ∠C = 54°
Thus, The value of m ∠C will be;
⇒ m ∠C = 54°

Suppose y varies directly with x and y=20 when x = 10. What is the value of y
when x = 30?
Answer:
y = 60
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
y = 2x ← equation of variation
When x = 30, then
y = 2 × 30 = 60

The Augello family is driving from Columbus to St. Louis at a constant rate of 65 miles per hour. The distance between the two cities is 420 miles. Write an equation in slope-intercept form to represent the distance y in miles remaining after driving x hours.
Answer:
[tex] y = -65x + 420 [/tex]
Step-by-step explanation:
Slope-intercept form equation is given as [tex] y = mx + b [/tex]
Where,
y = distance remaining
x = hours driven
m = slope/constant rate. In this case, the value of m would be -65. This means the distance will reduce at a constant rate of 65 miles per hour.
b = y-intercept, which is the initial value or the distance between the cities = 420
Plug in the values into the slope-intercept equation, to represent the distance y in miles remaining after driving x hours. You would have:
[tex] y = -65x + 420 [/tex]
The equation in slope intercept form is [tex]y =-65x + 420[/tex]
Linear functionA linear function is a function whose value changes at a constant rate.
The given parameters are:
Distance = 420 milesRate = -65 miles per hourA linear function is represented as:
[tex]y = mx + c[/tex]
Where
m represents the ratec represents the initial value i.e. the distanceSo, the function becomes
[tex]y =-65x + 420[/tex]
Hence, the equation in slope intercept form is [tex]y =-65x + 420[/tex]

=========================================================
Explanation:
Let y = -3*f(-3) + 2*f(3)
The goal is to find the value of y as some single numeric value.
We know that f(x) is an odd function. This means that
f(-x) = -f(x)
For all x in the domain of f(x).
Based on that, we can say
f(-3) = -f(3)
and,
y = -3*f(-3) + 2f(3)
-1*y = -1*(-3*f(-3) + 2*f(3)) ... multiply both sides by -1
-y = 3*f(-3) - 2*f(3)
-y = 3*f(-3) + 2*(-f(3))
-y = 3*f(-3) + 2*f(-3)
-y = 3*7 + 2*7 .... f(-3) replaced with 7
-y = 21+14
-y = 35
y = -35
-----------------------------------------------------
Here's a slightly different approach
f(-3) = 7
-f(3) = 7
Since f(-3) = -f(3)
We can then transform -f(3) = 7 into f(3) = -7 after multiplying both sides by -1
Therefore,
y = -3*f(-3) + 2f(3)
y = -3*7 + 2(-7)
y = -21 - 14
y = -35
-----------------------------------------------------
There are probably other routes to solve this problem.
Whichever path you take, you should find that -3*f(-3) + 2f(3) = -35

salad dressing is made by mixing lemon juice and olive oul in the ratio 2:5 by volume. the cost of lemon juice is $13.50 per litre. the cost of olive oil is $18 per litre. work out the ratio cost of lemon juice in salad dressing : cost of olive oil in the salad dressing. give your ratio in the simplest form
Answer: $3 : $4 or 3 : 4
Step-by-step explanation: To find the ratio of the cost of lemon juice in salad dressing, you’ll have to replace $13.50 or 13.5 to (135/10), which doesn’t affect the solution. Next, simplify (135/10) to get 27/2. After, divide 27/2 by 18, which is the other part of the ratio. (27/2 ÷ 18) Your final answer or result should end up as 3/4 but since we’re dealing with fractions 3:4, which is the simplified form of $13.50 : $18.00.
