David gasta el 20% de su salario en el pago de los servicios básicos de su casa del resto gasta el 50% en alimentación si al final se queda con 2000 Córdoba cuanto gana David
Answer:
Gana 6666,67 Córdoba de los cuales
gasta 3333,33 en alimentos y 1333,33 en servicios.
Step-by-step explanation:
Se queda 2000 Córdoba
Gasta el 20% de su salario para pagar los servicios básicos de su casa.
Gasta el 50% de su salario en comida.
Suponga que gana x cantidad
luego
x = 0,2x + 0,5x + 2000
x = 0,7x + 2000
x-0,7x = 2000
0,3 veces = 2000
x = 2000 / 0,3
x = 6666,67
Gana 6666,67 Córdoba de los cuales
gasta 3333,33 en alimentos y 1333,33 en servicios.
He keeps 2000 Córdoba
He spends 20% of his salary to pay for the basic services of his hous.
He spends 50% of his salary to pay on food.
Suppose he earns x amount
then
x= 0.2x+0.5x+2000
x= 0.7x+2000
x-0.7x=2000
0.3x= 2000
x= 2000/0.3
x= 6666.67
English
He earns 6666.67 Córdoba out of which
he spends 3333.33 on food and 1333.33 on services .

(7x + 10y = 11
(4x + 3y = -10
Answer:
x=-7
y=6
Step-by-step explanation:
7x+10y=11
4x+3y=-10
-3(7x+10y=11
10(4x+3y=-10
-21x-30y=-33
40x+30y=-100
19x = -133 (divide 19 on both sides)
x= -7
Now put the x in one of the original questions.
7(-7)+10y=11
-49+10y=11 (Add 49 to both sides)
10y=60 (Divide 10 on both sides)
y=6

what is the difference between the domain and the range of a function?
Answer:
The domain is all the x values of a function while the range is all the y values of a function.
Answer:
Step-by-step explanation:
The domain of a function is the set of input (x-) values for which the function is defined. The range is the set of output (y-) values; often there are limitations.
For example, the sine function y = sin x is defined for all real x; for every input x, there is a corresponding output y. The sine function has a limited range in that the minimum value of the sine is -1 and the max is +1. There is no graph above y = -1 or below y = +1.

A regular polygon with exterior angle of 45° is redrawn using a scale 1 : 5. If the actual length of the sides of the regular polygon is 10cm, calculate the perimeter of the scale drawing of the regular polygon.
Answer:
16 cm
Step-by-step explanation:
"regular polygon" means all sides and angles are the same.
the sum of all exterior angles must be 360 degrees.
so, how often do 45 fit into 360 ?
2 times in 90, which in turn fit 4 times into 360, so 8 times.
the polygon has 8 corners and 8 sides.
each side is originally 10cm
so the original perimeter is 8×10 = 80 cm
now, every side is reduced to 1/5th of the original size, this also reduces the perimeter by the same factor.
=> perimeter = 80×(1/5) = 80/5 = 16 x cm
control :
applying the scaling factor of 1/5th to every side transforms every side from 10 cm to 2 cm.
we still have 8 sides.
perimeter = 8 × 2 = 16 cm
correct

x = 18.028 (approximately 18)
Solve for x. Assume that lines which appear tangent are tangent. X=
Answer:
x = 32
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(x+18) * 18 = 30^2
(x+18) * 18 = 900
Divide each side by 18
(x+18) * 18/18 = 900/18
(x+18) = 50
Subtract 18 from each side
x+18-18 = 50-18
x=32
Answer:
50

You own a house with an appraised value of $300,000. Your equity in the home is $125,000. What is your mortgage balance?
Answer:
The mortgage balance is $175,000
Step-by-step explanation:
Remember: House value = equity + mortgage. Therefore,
$300,000 = $125,000 + mortgage balance
The mortgage balance is $175,000.

A pole that is 3.4 m tall casts a shadow that is 1.61 m long. At the same time, a nearby building casts a shadow that is 36.75 m long. How tall is the building?
Round your answer to the nearest meter.
Answer:
Step-by-step explanation:
Set this up as a proportion with pole/building height on the top and shadow length on the bottom, using x for the unknown, which is the height of the building:
[tex]\frac{pole/building}{shadow}:\frac{3.4}{1.61}=\frac{x}{36.75}[/tex] and cross multiply to solve:
1.61x = 124.95 so
x = 78 m

What is an equation of the line passing between(4, -6) and (12, -8)?*
Answer:
y= -1/4x - 5
Step-by-step explanation:
first you need to find the slope.
to do this you can use the equation: change in y/change in x which is also y2 - y1/x2-x1
-8 - (-6)/12-4
-2/8
-1/4 = slope
since the line's equation is y = mx + b, we still need to find the y-intercept. we can do this by just plugging in one of the points
-6 = -1/4(4) + b
-6 = -1 + b
-5 = b
so the final equation is y= -1/4x - 5
What is the value of x?
26°
オー
X=
[?]
Enter
Answer:
154 degrees
Step-by-step explanation:
A quadrilateral has the sum of the interior angles that is 360 degrees
for the tangent theorem we know that the angles where the lines intercept the circumference have a value of 90 degrees
x + 90 + 90 + 26 = 360
x + 206 = 360
x = 360 - 206
x = 154 degrees

Identify each situation as a permutation or a combination.
1. choosing friends to invite to a party
2. choosing your top 10 favorite actors
Answer:
1. Combination
2. Permutation
Step-by-step explanation:
Permutations occur in cases where the order of something changes the arrangement (e.g. Choosing letters of a password). Combinations occur when the order of something does not matter (e.g. choosing three donut flavors).
1. Since the order of which you choose and invite your friends does not change who you've invited, this is a combination (order does not matter).
2. When ranking a top-10 list, the order of your ranking affects the ranking itself and makes a difference (order matters). Therefore, this situation is a permutation.
Solve the equation. 6g = 48 what does g equal?
Answer:
8
Step-by-step explanation:
First we need to figure out what g equals
Since 6 x 8 = 48 your answer would be 8
6 x 8 = 48
~ LadyBrain
The value of g that satisfies the equation is 8.
To solve the equation 6g = 48 and find the value of g, we can isolate the variable g by dividing both sides of the equation by 6:
6g / 6 = 48 / 6
This simplifies to:
g = 8
Therefore, g equals 8. By dividing both sides of the equation by 6, we find that when g is multiplied by 6, it results in 48. Hence, the value of g that satisfies the equation is 8.

Answer:
a) 40 is the interquartile range
descriptive statistics, the interquartile range, also called the midspread, middle 50%, or H‑spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q₃ − Q₁.
b).
The first thing you always need to do before estimating fractions is to round each fraction either to the nearest 0, 1/2, or 1. Example #1. Estimate 3/7 + 5/9. Notice that 3/7 is close to 1/2 and 5/9 is also close to 1/2. Therefore, an estimate for 3/7 + 5/9 is 1/2 + 1/2 = 1.
