Luna runs 5,000 m in 35 minutes during a cross-country meet. What was her speed?
A. 0.007 m/min
B. 4,965 N
C. 5,035 N
D. 143 m/min
Answer:
D
Step-by-step explanation:
to calculate speed ( or v for velocity ) divide the space traveled by the time it took to travel that distance.
v = S/t = 5000m/35min = 143 m/min

SOLVE FOR X PLEASE IM STUCK ON THIS ONE
Answer:
x = -5
Step-by-step explanation:
If the measure of angle 1 = 9x +6 and the measure of angle 2 = 2 (5x - 3), find x
Answer:
x=12
Step-by-step explanation:
<1 and <2 are equal since they are alternate exterior angles for parallel lines
9x+6 = 2(5x-3)
distribute
9x+6 = 10x-6
Subtract 9x from each side
9x+6-9x= 10x-6-9x
6 = x-6
Add 6 from each side
6+6 =x-6+6
12=x
Answer:
See below for answer.
Step-by-step explanation:
m∠1 = m ∠2 If lines are parallel, then alternating exterior angles are =
Therefore
a ║ b Given in the figure
m∠1 = m ∠2
9x + 6 = 2(5x - 3)
9x + 6 = 10x - 6 Distributive
9x + 12 = 10x Addition
12 = x Subtraction

solve the equation 2y=7(y−2)+4
y =
Answer:
y = 2
Step-by-step explanation:
Hi there!
[tex]2y=7(y-2)+4[/tex]
[tex]2y=7y-14+4\\2y=7y-10\\0=5y-10\\5y=10\\y=2[/tex]
I hope this helps!
Step-by-step explanation:
2y = 7(y-2) + 4
→ 2y = 7y - 14 + 4
→ 2y = 7y - 10
→ 2y - 7y = -10
→ - 5y = -10
Therefore, y = 10:5 = 10/5 = 2 Ans.

Katie has $6,500 in a saving account if she earns 6% interest every month how much money does Katie have in your bank account after half a month how much money does Kaite have in her bank account after half a year.
AND IF SOMEONE DARES TO PUT A LINK PLEASE DON'T
Answer:
bad question sadly she would technechly have 6500 after half a month bc you only apply interest after the minth but im guessing she wants us to half it to make it for half the month so 6500*0.03= $195 in half the month
and half a year would be 6500*.06*6= $2340 after half a year

If

If
m ≤ f(x) ≤ M
for

where m is the absolute minimum and M is the absolute maximum of f on the interval [a, b], then m(b − a) ≤ f(x) dx ≤ M(b − a).
f(x) dx ≤ M(b − a).
Use this property to estimate the value of the integral.

(10x − 20 sin(x)) dx

Use the fact that -1 ≤ sin(x) ≤ 1.
Then
20 ≥ -20 sin(x) ≥ -20 … … … (multiply each side by -20)
-20 ≤ -20 sin(x) ≤ 20 … … … (swap the endpoints)
10x - 20 ≤ 10x - 20 sin(x) ≤ 10x + 20 … … … (add 10x to each side)
and over the interval [7, 8], we have
7 ≤ x ≤ 8
70 ≤ 10x ≤ 80 … … … (multiply each side by 10)
so that the whole integrand is bounded by
70 - 20 ≤ 10x - 20 sin(x) ≤ 80 + 20
50 ≤ 10x - 20 sin(x) ≤ 100
Take m = 50 and M = 100. It follows that
[tex]50(8-7) \le \displaystyle \int_7^8 (10x-20\sin(x)) \, dx \le 100(8-7)[/tex]
which places the value of the integral between 50 and 100.

Mi tío compró un terreno campestre de forma rectangular que mide 3/4 hm de largo y 1/2 de ancho, ¿Cual es su área ?
Answer:
¿Cómo y por qué? El área de un rectángulo se represa mediante la relación:
Área = largo · ancho
En este caso conocemos:
3/4 hm de largo: l = 3/4
1/2 hm de hm: a = 1/2
La unidad hm, son los hectómetros. Un hectómetro equivale a 100 metros.
Calculamos el área:
A = (3/4 · 1/2) hm²
The area of rectangular piece of land that measures 3/4 m long and 1/2 m wide is 3/8 square meters
What is the Area of Rectangle?The area of rectangle is -
A = L x B
Given is a rectangular piece of land that measures 3/4 m long and 1/2 m wide.
We can calculate the area using the formula -
Area = Length x Width
A = 3/4 x 1/2
A = 3/8 square meters
Hence, the area of rectangular piece of land that measures 3/4 m long and 1/2 m wide is 3/8 square meters

1. The order of the angles from smallest to greatest is PQR, QRP, PRQ.
2. The value of x + y is (2x + 179)/7.
3. Triangle GHK is isosceles because angles H and K are congruent.
4. The hypotenuse is always the longest side of a right triangle.
1. To determine the order of the angles in the given triangle, we can use the fact that the largest angle will be opposite the longest side. Let's compare the lengths of the sides:
- PQ = 5.6
- PR = 6.1
- QR = 5.2
From the given lengths, we can see that PR is the longest side. Therefore, angle PRQ will be the largest angle. Now we need to compare the remaining two angles, PQR and QRP. Since QR is the shortest side, angle PQR will be the smallest angle. This means that the order of the angles from smallest to greatest is: PQR, QRP, PRQ.
2. In a triangle, the sum of the interior angles is always 180 degrees. Given the angles in terms of y and x, we can set up an equation:
(4y - 8) + (3y + 9) + 5x = 180
Combining like terms:
7y + 5x + 1 = 180
To find the value of x + y, we need to solve for y in terms of x first. Let's isolate y:
7y = 180 - 5x - 1
7y = 179 - 5x
y = (179 - 5x)/7
Now, we can substitute this expression for y into the equation x + y:
x + y = x + (179 - 5x)/7
To simplify further, we can distribute the division:
x + y = (7x + 179 - 5x)/7
x + y = (2x + 179)/7
Therefore, the value of x + y is (2x + 179)/7.
3. To prove that triangle GHK is isosceles, we need to show that two of its sides are congruent. Given that angle H is 56 degrees, and angles IKJ and H are alternate interior angles, we know that angle IKJ is also 56 degrees. Since angle IKJ is 68 degrees, this implies that angle KJI is 112 degrees (180 - 68 = 112).
Now, considering triangle GHK, we have:
- Angle G = 180 - (angle H + angle K) = 180 - (56 + 112) = 180 - 168 = 12 degrees
Since angle G is 12 degrees, and angles G and H are alternate interior angles, we know that angle H is also 12 degrees.
Therefore, we have two angles in triangle GHK that are congruent, namely angle H and angle K, making it an isosceles triangle.
4. Proof that the hypotenuse is always the longest side of a right triangle:
Let's consider a right triangle with sides a, b, and c, where c is the hypotenuse.
According to the Pythagorean theorem, which is a fundamental property of right triangles, we have:
[tex]c^2 = a^2 + b^2[/tex]
To compare the lengths of a, b, and c, let's square all the sides:
[tex]a^2, b^2, and c^2[/tex] are all positive since they are the squares of real numbers.
Now, if we examine the inequality [tex]a^2 + b^2 < c^2[/tex], we can see that the sum of the squares of the shorter sides is less than the square of the hypotenuse.
Since [tex]c^2 = a^2 + b^2[/tex], the inequality becomes [tex]a^2 + b^2 < a^2 + b^2[/tex], which is not possible.
Therefore, we can conclude that in a right triangle, the hypotenuse (side c) is always the longest side.
