Se requiere dos personas para construir una barda de 20 m de largo y 1.5 m de alto en dos días ¿cuántas personas se necesitan para construir otra barda igual en mediodía?
Answers
Answer:
Definamos R como la "velocidad" a la que una persona puede construir la barda dada.
Supongamos que la persona necesita un tiempo T para construir la barda, entonces tenemos la relación:
R*T = 1 barda.
Si dos personas trabajan juntas la velocidad de trabajo va a ser (R + R), y sabemos que ellos pueden completar el trabajo en 2 días, entonces:
(R + R)*2 días = 1 barda
(2*R)*2 días = 1 barda
(2*R) = (1/2) barda por día
R = (1/2)*(1/2) barda por día = (1/4) barda por día.
Esto significa que una persona puede completar un cuarto de la barda en un día de trabajo.
Ahora queremos saber cuantas personas se necesitan para construir una barda en solo medio día, entonces debemos resolver:
(N*R)*0.5 días = 1 barda
Donde N es el número de personas que queremos obtener.
(N* (1/4) barda por día)*0.5 días = 1 barda
N*(1/4) barda por día = (1/0.5) bardas por día = 2 bardas por día
N = 2/(1/4) = 2*4 = 8
N = 8
Se necesitan 8 personas para construir una barda en medio día.

Part A: Mike wants to join a gym. He has to pay an initiation fee of $16 and equal monthly payments for the year. The most he wants to pay is $580 for the year for his gym membership. a.) Write an inequality that you can use to determine the most he would want to spend for his monthly payments.
Part B: Now use your inequality from 15a to determine how much Mike’s monthly gym payment can be if the most he wants to pay is $580 for the year for his gym membership..
Answers
Answer:
Part A: [tex]12x+16\leq 580[/tex]
Part B: $47 per month
Step-by-step explanation:
Part A: 12 months in a year. Pays x amount of $ per year, with an additional $16 initiation fee. He wants to spend less than $580 total a year. Thus, [tex]12x+16\leq 580[/tex].
Part B: Solve the inequality for x.
$580 - $16 = $564
x = $564/12 = $47

What is the area of the trapezoid?
A. 24 mm2
B. 26 mm2
C. 32 mm2
D. 40 mm2
Answers
Answer:
A= 24 m
Step-by-step explanation:
The formula for the area of a trapezoid is A= [tex]\frac{a+b}{2}[/tex] x h.
Using the formula you plug in the values:
A= [tex]\frac{4 + 12} 2}[/tex] x 3
2. Now you simplify the equation and solve
A = [tex]\frac{16}{2}[/tex] x 3
A = 8 x 3
A = 24

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9kg weighs 63 N . Find the weight of an object whose mass is 5kg.
Answers
Answer:
35
Step-by-step explanation:
9Kg =63N
5Kg=X (Cross Multiple)
=X×9 =5×63
divide both sides by 9
X=5×63
---------
9
=35
Answer:
35 N
Step-by-step explanation:
let w = weight of object
and m = mass of object
w = mk where k is the constant of proportion
63 = 9k
k = 7
So, w = 7m
w = 7(5) = 35 N

They should add up to be 360 so you can set up an equation like so
120+90+100+x=360
And x = 50
Answer:
x = 50°
Step-by-step explanation:
The triangle has 3 congruent sides and is therefore equilateral.
The 3 angles are then congruent, each 60°
The left angle in the quadrilateral is adjacent to 60° of the triangle
180° - 60° = 120° ← angle inside quadrilateral
The sum of the interior angles of a quadrilateral = 360°
Subtract the sum of the angles from 360° for x
x = 360° - (120 + 90 + 100)° = 360° - 310° = 50°

Quadrilaterals A and B are similar.
Find the values of the sides marked

y
:
Answers
Answer:
x = 17.5
y = 5
Step-by-step explanation:
Similar means that corresponding angles (same colors in this case) are the same. Rotate the 2nd figure on the right in your mind until the angle label colors fit the 1st figure, just so you can tell what's what. Then you can create ratios with corresponding sides that include only one of the unknowns. So 1st we use
x/7 = 15/6
x = 15/6 * 7
x = 17.5
and
y/12.5 = 6/15
y = 6/15 * 12.5
y = 5
What is the minimum or maximum value of the equation of this equation?
f(x) = -(x-8)^2 -30
Answers
9514 1404 393
Answer:
f(8) = -30 is the maximum
Step-by-step explanation:
The equation is that of a parabola in vertex form:
y = a(x -h)^2 +k . . . . . . . . (h, k) is the vertex; 'a' is the scale factor
Comparing this form to the given equation, we have ...
f(x) = -(x -8)^2 -30
a = -1h = 8k = -30That is, the scale factor is -1, and the vertex is (8, -30).
When the scale factor is negative, the graph opens downward and the vertex is a maximum. The maximum value is -30.
Andrea uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 1 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer:
7.35
Step-by-step explanation:
Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls
1/4 of this amount is white paint
= 1/4 × 9.8
= 0.25×9.8
= 2.45
Therefore the amount of blue paint can be calculated as follows
9.8-2.45
= 7.35
Hence 7.35 are blue paint

The minimum charge for first 175 of telephone calls
is Rs. 300. If the charge of each additional call is Rs.
3.50 , how much will be charge for 389 telephones
calls?
Answers
Answer:
Rs. 1,049
Step-by-step explanation:
Charge for 175 of telephone calls
= Rs. 300
Additional charge per call = Rs.
3.50
how much will be charge for 389 telephones calls?
389 telephones calls - 175 telephones calls = 214 telephones calls
Charge for 389 telephones calls = charge of 175 telephone call + (charge of 389 telephones calls - 175 telephones calls)
= Rs. 300 + charge of 214 telephones calls
= Rs. 300 + 214(Rs. 3.50)
= Rs 300 + Rs. 749
= Rs. 1,049

Answers
Answer:
116º
Step-by-step explanation:
Okay so mRS and mUT is parallel, according to the symbols. So, we have to make an equation.
6x-28 = 4x+20
Now we just solve for x, lets subtract 20 on both sides, and the equation now becomes
6x - 48 = 4x
Now subtract 6x on both sides.
-48 = -2x
Now divide -2 on both sides to isolate x
24=x
Now we know x is equal to 24, so now we plug in 24 with x.
6(24) - 28 = 116.
So, mRS = 116º
Hope this helps!!
