Pat walked around a circular track she knew that the distance across The center was 100 meters if she walked around the entire track how far did she walk
Answer:
314.16 m
Step-by-step explanation:
The distance across the track is 100 metres. This means that the diameter is 100 m.
The track is circular, so, we need the circumference.
The circumference of a circle is given as:
C = πD
where D = diameter
Therefore, the circumference of the track is:
C = π * 100 = 314.16 m
She walked a distance of 314.16 m

Rafael ha comprado 185,8 kg. de manzanas y 300,2 kg. de naranjas. ¿Cuánto más pesan las naranjas que las manzanas? ¿Cuánto pesa su compra?
Answer:
a.114.4kg
b. 486kg
Step-by-step explanation:
Firstly , we want to know the value with which the apples weigh more than the oranges
To calculate this, we simply subtract the weight of the oranges from that of the apple
Mathematically, that would be ;
300.2-185.8 = 114.4kg
The total weight of the things bought is calculated by adding both weights together
That would be 185.8 + 300.2 = 486 kg

En el videojuego "City Sweet" hay una ciudad sitiada en la que hay víveres para 2000 personas durante 15 días, un grupo de 500 habitantes decide rendirse. ¿Cuántos días podrán resistir los demás, si los que se rinden no se llevan víveres?
Answer:
20 days.
Step-by-step explanation:
In this case we must make an inverse proportionality rule, it is inverse because the fewer people there are, the more days must survive. In other words, we know that 2000 people can resist for 15 days, now, if there are no longer 2000 people, but 500 less, that is, 1500 (2000 - 500) how many days can they resist.
people days
2000 15
1500 x
x = 2000 * 15/1500
x = 20
That is, they could last 20 days.

From a point on the ground the angle of elevation of the top of a tower is x°. Moving 150 meters away from that point the angle of elevation was found to be y° .If tan x=3/4 and tan y=5/7 find the height of the tower.
Answer:
2250m
Step-by-step explanation:
Step 1
Since
Hence,
tan x = 3/4
tan y=5/7
tan x = BA/ CA where BA = height and CA = distance
3/4 = h/ d
4h = 3d
h = 3d/4.......... Equation 1
tan y = BA / DA + 150m
5/7 = h/d + 150
7 × h = 5(d + 150)
7h = 5d + 750............ Equation 2
Since h = 3d/4
7(3d/4) = 5d + 750
21d/4 = 5d + 750
Multiply both sides by 4
21d = 4(5d + 750)
21d = 20d + 3000
21d -20d = 3000
d = 3000
Distance (d) = 3000m
Substitute 3000m for d in equation 1
h = 3d/4
h = 3 × 3000/4
h = 2250m
Answer:
2250mStep-by-step explanation:
[tex]tangent=\dfrac{opposite}{adjacent}[/tex]
We have:
[tex]\tan x^o=\dfrac{3}{4}\\\\\tan y^o=\dfrac{5}{7}[/tex]
By definition of tangent, we have:
[tex]\tan x^o=\dfrac{AB}{AC}\\\\\tan y^o=\dfrac{AB}{AC+150}[/tex]
Therefore we have the system of equations:
[tex]\left\{\begin{array}{ccc}\dfrac{AB}{AC}=\dfrac{3}{4}&(1)\\\\\dfrac{AB}{AC+160}=\dfrac{5}{7}&(2)\end{array}\right[/tex]
From (1)
[tex]\dfrac{AB}{AC}=\dfrac{3}{4}[/tex] cross multiply
[tex]3AC=4AB[/tex] divide both sides by 3
[tex]AC=\dfrac{4AB}{3}[/tex]
Substitute it to (2):
[tex]\dfrac{AB}{\frac{4AB}{3}+150}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB}{3}+\frac{3\cdot150}{3}}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB}{3}+\frac{450}{3}}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB+450}{3}}=\dfrac{5}{7}\\\\AB\cdot\dfrac{3}{4AB+450}=\dfrac{5}{7}[/tex]
[tex]\dfrac{3AB}{4AB+450}=\dfrac{5}{7}[/tex] cross multiply
[tex](3AB)(7)=(5)(4AB+450)\\\\21AB=(5)(4AB)+(5)(450)[/tex]
[tex]21AB=20AB+2250[/tex] subtract 20AB from both sides
[tex]AB=2250[/tex]
Such a tower height is rather impossible, but this is the solution.
What is the solution to the system of equations?
-2x + 3y = 13
3x + 4y = 6
Answer:
x = -2
y = 3
Step-by-step explanation:
You are given a system of two linear equations:
-2x + 3y = 13
3x + 4y = 6
One of the good ways to solve this system is trying to eliminate one variable (x or y), calculate the remaining variable and substitute the calculated variable back into system to solve for eliminated variable.
Here, we will manipulate the original system, so that we can easily eliminate x.
Let's multiply both sides of the first equation by 3 and the second equation by 2 (this manipulating step does not change the original system of equations).
3*(-2)x + 3*3y = 3*13
2*3(x) + 2*4y = 2*6
<=>
-6x + 9y = 39
6x + 8y = 12
Now, we add up two equations, left side + left side, right side + right side, we obtain:
-6x + 9y + 6x + 8y = 39 + 12
or
17y = 51
We divide both sides of equation by 17, to get y.
=> y = 51/17 = 3
Substitute y = 3 back into the first equation of system (or the second equation, it doesn't matter, here we choose the first one).
=> -2x + 3*3 = 13
=> -2x + 9 = 13
=> -2x = 4
=> x = -2
=> The solution of this system is (x, y) = (-2, 3)
Hope this helps!

Given: w ∥ x and y is a transversal. Prove: ∠3 and ∠5 are supplementary. Parallel and diagonal lines w and x are cut by horizontal transversal y. On line w where it intersects with line y, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 1, 3, 4, 2. On line x where it intersects with line y, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 5, 7, 8, 6. Use the drop-down menus to complete the proof. Given that w ∥ x and y is a transversal, we know that ∠1 ≅∠5 by the . Therefore, m∠1 = m ∠5 by the definition of congruent. We also know that, by definition, ∠3 and ∠1 are a linear pair so they are supplementary by the . By the , m∠3 + m ∠1 = 180. Now we can substitute m∠5 for m∠1 to get m∠3 + m∠5 = 180. Therefore, by the definition of supplementary angles, ∠3 and ∠5 are supplementary.
Answer:
1.Corresponding angles theorem
2.Linear postulate
3.By the definition of supplementary angles
Step-by-step explanation:
We are given that
[tex]w\parallel x \ and \ y[/tex] is a transversal.
We have to prove [tex]\angle 3[/tex] and [tex]\angle 5[/tex] are supplementary
Proof:
1.Given that [tex]w\parallel x \ and \ y[/tex] is a transversal.
We know that [tex]\angle 1\cong \angle 5[/tex]
Reason:Corresponding angles theorem
Therefore, [tex]m\angle 1=m\angle 5[/tex]
by the definition of congruent.We also know that, by definition, angle 3 and angle 1 are a linear pair.
Therefore, they are supplementary by linear pair postulate
By the definition of supplementary angles
[tex]m\angle 3+m\angle 1=180^{\circ}[/tex]
Now, we can substitute [tex]m\angle 5=m\angle 1[/tex]
Then, we get
[tex]\m\angle 3+m\angle 5=180^{\circ}[/tex]
Therefore, by the definition of supplementary angles,angle 3 and angle 5 are supplementary

You can work a maximum of 40 hours a week. You need to make $440 in order to cover your expenses. Your office job pays $12 an hour and your babysitting job pays $10 an hour. What is the least possible number of hours you can work at your office job and still meet the requirements?
Answer:
The least possible number of hours you can work at your office job is 20.
Step-by-step explanation:
$12/h ----> office
$10/h ----> babysitting
"o" -----> hours office job
"b" -----> hours babysitting job
[tex]12x + 10y = 440\\x + y \leq 40\\12x + 10y = 440 -----> 6x + 5y = 220 ----> y = \frac{220-6x}{5} \\\\x + y \leq 40\\x + \frac{220-6x}{5} \leq 40\\5x + 220 - 6x \leq 200\\x \geq 20[/tex]
A certain television is advertised as a 17-inch TV (the diagonal length). If the width of
the TV is 8 inches, how many inches tall is the TV?
Answer:
15 inches
Step-by-step explanation:
We can solve this problem using the Pythagorean theorem. The formula is:
[tex]a^{2} + b^{2} = c^{2}[/tex]
where 'c' is the hypotenuse (the longest side) and 'a' and 'b' are the legs (the other sides).
First, draw a diagram for the problem. (See the photo attached below)
We know the other leg is 8 and the hypotenuse is 17. 'a' is the missing side.
a = ?
b = 8
c = 17
Substitute the values into the equation.
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]a^{2} + 8^{2} = 17^{2}[/tex]
Rearrange to isolate 'a'
[tex]a^{2} = 17^{2} - 8^{2}\\[/tex] Square root both sides
[tex]a = \sqrt{17^{2} - 8^{2}}[/tex] Square each number
[tex]a = \sqrt{289-64}[/tex] Subtract under the root
[tex]a = \sqrt{225}[/tex] Find the square root
[tex]a =15[/tex] Final answer
Therefore, the TV is 15 inches tall.
