Megan has a piece of fabric which is a right triangular shape. The length of leg 1 is 4 m. The length of the other leg is twice the length of leg 1. What would be the length of the third side of the fabric?
8.94 m
7.21 m
6.93 m
4.47 m
Answer:
8.94 m
Step-by-step explanation:
Use the Pythagorean Theorum - [tex]a^2 + b^2 = c^2[/tex]. Use leg 1 as a, leg 2 as b, and the third side as c.
We know leg 1 is 4, and that leg 2 is twice as long as leg 1...
[tex](4)^2 + (4*2)^2 = c^2[/tex]
Now, we use the Order of Operations to find [tex]c^2[/tex]...
[tex]4^2+8^2=c^2\\16+64=c^2\\80=c^2[/tex]
Now, we find the square root of [tex]c^2[/tex] to find c...
[tex]\sqrt{80} =8.94[/tex]
So, the length of the third side is 8.94 m.

4 raised to power two minus 8u minus 9=0
Answer: u = [tex]\frac{7}{8}[/tex] or 0.875
Step-by-step explanation:
Let us convert this statement to a question
[tex]4^{2}[/tex]-8u-9 = 0
16-8u-9 = 0
-8u = 0+9-16
-8u = -7
u = -7 ÷ -8
u = [tex]\frac{7}{8}[/tex] or 0.875
Dan invests £18790 into his bank account. He receives 5.9% per year simple interest. How
much will Dan have after 2 years? Give your answer to the nearest penny where appropriate.
Answer: £21007.22
Step-by-step explanation:
First, find the interest amount using the formula SI = (P × R × T) / 100.
SI = interest amount P = principle amount = £18790R = interest rate(in percentage) = 5.9T = time(in years) = 2SI = (P × R × T) / 100 = (18790 × 5.9 × 2)/100 = 221722/100 = £2217.22
The total amount = principle amount + interest amount
= £18790 + £2217.22 = £21007.22

28.35 g in an ounce and 2.21 lb in a kilogram. convert 3 kilograms to ounces. Is conversion correct? Explain. please
Answer:
Whether her conversion is correct or not, you can just base it on the true answer. For this problem, we apply the technique of dimensional analysis. You can like units if they both appear on the numerator and the denominator side. The solution is as follows:
Mass in ounces = 3 kg * (1,000 g/ 1 kg) * (1 ounce/28.35 g) = 105.82 ounces
The puppy needs to catch a train that is moving at 8km/hr. she is 100 meters away and running at 10km/hr. How far will the train have traveled before the puppy is able to jump on?
The rabbit will jump on the train after the train moves 0.4km
The given parameters are:
[tex]d = 100m[/tex] -- distance between the puppy and the train
[tex]s_1 = 8km/hr[/tex] -- the speed of the train
[tex]s_2 = 10km/hr[/tex] --- the puppy's speed
Required
The distance where the puppy catch up with the train
First, we calculate the relative speed (rs) of the puppy to the train
[tex]rs =s_2 - s_1[/tex]
[tex]rs =10km/hr - 8km/hr[/tex]
[tex]rs =2km/hr[/tex]
Calculate the time to catch up with the train using:
[tex]Time = \frac{Distance}{Speed}[/tex]
[tex]t = \frac{100m}{2km/hr}[/tex]
Convert km to m
[tex]t = \frac{100m}{2*1000m/hr}[/tex]
[tex]t = \frac{100m}{2000m/hr}[/tex]
[tex]t = 0.05hr[/tex]
Calculate the distance to catch up with the train using:
[tex]Distance = Speed * Time[/tex]
[tex]d= s_2* t[/tex] --- speed of the train multiplied by the time
So, we have:
[tex]d = 8km/hr * 0.05hr[/tex]
[tex]d = 8km * 0.05[/tex]
[tex]d = 0.4km[/tex]

Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan.
How old is Ishaan now?
Answer:
Ishaan is currently 15 years old.
Step-by-step explanation:
Let B represent Ben's current age and I represent Ishann's current age.
Ben is four times as old as Ishaan. In other words:
[tex]B=4I[/tex]
Six years ago, Ben was six times as old as Ishaan. In other words:
[tex]B-6=6(I-6)[/tex]
Solve for I. Substitute:
[tex](4I)-6=6(I-6)[/tex]
Distribute:
[tex]4I-6=6I-36[/tex]
Subtract 4I from both sides and add 36 to both sides:
[tex]2I=30[/tex]
And divide both sides by two. Hence:
[tex]I=15[/tex]
Ishaan is currently 15 years old.
Answer:
Age of Ishaan = 15 years
Step-by-step explanation:
Let Ishaan's age = x years
Age of Ben = 4 * x = 4x years
6Years ago:
Age of Ishaan = x - 6
Age of Ben = 4x - 6
6 years ago, Ben was 6 times as old as Ishaan
So, Age of Ben = 6 * Ishaan's age
4x - 6 = 6 *(x-6)
4x - 6 = 6x - 36
Add 36 to both sides
4x - 6 + 36 = 6x
4x + 30 = 6x
Subtract '4x' from both sides
30 = 6x - 4x
30 = 2x
2x = 30
Divide both by 2 sides
x = 30/2
x = 15

What is the graph of f SOMEONE help me please
Answer:
f(x) = 1/2x + 6
Step-by-step explanation:
So before we even look at the first given formula, let's use the second formula: f(x) = -5.
Plug this formula into the x:
0 <= -5 <= 7
Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?
No, this is false.
So the formula, f(x) = -5, is not the graph of f.
That only leaves one possible option!

if the distance from one base to the other is 10 mm long and each triangle is 0.5 mm thick how many triangles would it take to fill up the prism
Answer:
2. 20
Step-by-step explanation:
2. The distance from one base of the prism to the other base of the prism, d = 10 mm
The thickness of each triangle to be used to fill the prism, t = 0.5 mm
The number of triangles needed, n, is therefore;
[tex]n = \dfrac{d}{t}[/tex]
Where;
d represents the distance between the bases of the prism, t, represents the thickness of each triangle, and n represents the number of triangles it would take to fill up the prism
Therefore;
[tex]n = \dfrac{10 \, mm}{0.5 \, mm} = 20[/tex]
The number of triangles it would take to fill up the prism, n = 20

Christine said that y =√16x is a horizontal stretch by a factor of 1/16. Amanda said that it is a vertical stretch by a factor of 4. Who is correct and why?
Answer:
y = [tex]\sqrt{16}[/tex] x
that is equal to y = 4x
[tex]\sqrt{16}[/tex] = 4
when graphing (x,y) the x is the horizontal value of the point (east west)
and the y in the vertical (north south) ....
if you have y = x it would be a 45 degree line that goes from the lower left to the upper right....
if you compare the red line the point 1,1 (y=x) versus 1,4 (y=4x) in the blue line you will see that it is "stretched" upward

Study the diagram of circle C, where two chords, AB¯¯¯¯¯¯¯¯ and DE¯¯¯¯¯¯¯¯, are equidistant from the center.
The diagram as described in the problem.
If AB=3x−7, and DE=5(x−5), what is the length of AB¯¯¯¯¯¯¯¯?
Enter the correct value.
Answer:
Step-by-step explanation:
If AB and DE are equidistant from the center, that means that they are the same length. We set the equations equal to one another and solve for x:
3x - 7 = 5(x - 5) and
3x - 7 = 5x - 25 and
18 = 2x so
x = 9. Now we sub that into the expression for AB (or DE since they're the same length):
3(9) - 7 = 20
Both AB and DE measure 20 units.

what is the formula to calculate VAT percentage
Answer:
Take the gross amount of any sum (items you sell or buy) – that is, the total including any VAT – and divide it by 117.5, if the VAT rate is 17.5 per cent. (If the rate is different, add 100 to the VAT percentage rate and divide by that number.)
Answer:
divide by 117.5 if the rate different, add 100 to the percentage and divide by the number therefore multiply by 100 to get the total
