If Lisa works part-time, she will make 35% less than she does now.
How much will her monthly net income be?
What will their new total net income be?
Answers
Answer:
Lisa: $3302Family: $11372Step-by-step explanation:
Given a family net income of $13150, Lisa's current annual gross of $76200, deductions of 20% of Lisa's gross salary, you want to know Lisa's monthly net income and the new family net income if Lisa makes 35% less by working part-time.
Lisa's incomeLisa's current annual income is $76200, and her annual net income is 80% of that, or $60960. On a monthly basis, her net income is ...
$60960/12 = $5080 . . . . . . Lisa's current net monthly income
If her income is reduced by 35%, the reduction is ...
0.35 × $5080 = $1778
Then Lisa's part-time monthly net income will be ...
$5080 -1778 = $3302 . . . . . Lisa's part-time monthly net income
Family incomeThe family net income will be reduced by the same amount:
$13150 -1778 = $11372 . . . . . new family monthly net income
__
Additional comment
It appears the total of budgeted items is $10343, so those items can be paid even if Lisa works part-time. The family's current surplus income of $2807 would be reduced to $1029, about a 63% reduction. That gives a lot less cushion to pay for off-budget expenses that may come up.

Step-by-step explanation:
The diagram of the question is presented in the attached image to this question
English Translation
Efraín has a rectangular land whose area is (120m² + 280m) as shown in the figure. According to these data, how much does side f measure?
a) 12 m² + 35
b) 15 m + 35 cm

d) 15 m + 35
3.- A child made four plasticine figures: two quadrangular prisms and two cylinders. In which figure did you occupy the most amount of modeling clay? JUSTIFY YOUR ANSWER
Solution
2) The area of a rectangle is given as
Area = Length × Breadth
Area = (120m² + 280m)
Length = f
Breadth = 8m
(120m² + 280m) = f × 8m
f = (120m² + 280m)/(8m)
f = (15m + 35)
Option D is correct.
f = (15m + 35)
3) For the second question, the images for the question and the dimensions of the figures aren't provided, hence, a very accurate answer can be provided. But without This, we can only speculate.
The figure that would use the most clay is the figure whose volume is the highest if the volumes of each of the figures are calculated.
Volume of a quadrangular prism = (Area of base) × (perpendicular height)
Volume of a cylinder = (Area of base) × (Height) = (πR² × H) = πR²H
So, it is in the evaluation of these volumes that the solution of this question is obtained.

If you spin the spinner 72 times, what is the best prediction possible for the number of times it will land on yellow?
Answers
the best prediction possible for the number of times the spinner will land on yellow if it is spun 72 times is 12. This means that out of 72 spins,
how to solve probability
If the spinner has 12 equal parts and 2 of them are yellow, then the probability of the spinner landing on yellow is 2/12, or 1/6. This means that out of every 6 spins, we can expect the spinner to land on yellow once.
To find the best prediction for the number of times the spinner will land on yellow if it is spun 72 times, we can use the idea of expected value. The expected value of an event is the average value we would expect to see if the event were repeated many times.
In this case, the expected value of the number of times the spinner will land on yellow in 72 spins is simply the probability of landing on yellow multiplied by the number of spins:
Expected value = Probability of yellow x Number of spins
Expected value = (1/6) x 72
Expected value = 12
Therefore, the best prediction possible for the number of times the spinner will land on yellow if it is spun 72 times is 12. This means that out of 72 spins, we can expect the spinner to land on yellow approximately 12 times on average. However, it's important to remember that this is just a prediction based on probability, and the actual number of yellow spins may vary.

Si Verónica, Ana y Luis están pintando una barda y se les paga un total de 300 unidades monetarias (por ejemplo, dólares, pesos, etc.), para determinar cuánto dinero debería recibir cada uno, necesitamos más información sobre cómo se distribuye el trabajo entre ellos.
Si los tres contribuyen de manera equitativa y realizan la misma cantidad de trabajo, podrían dividir el pago de manera igualitaria. En ese caso, cada uno recibiría 100 unidades monetarias (300 dividido entre 3).
Sin embargo, si uno de ellos realiza más trabajo o tiene una mayor responsabilidad en la tarea, podría ser justo que reciba una porción mayor del pago. En ese caso, la distribución de los 300 unidades monetarias dependerá de un acuerdo previo entre ellos sobre cómo se divide el pago en función de la cantidad o calidad del trabajo realizado.
Es importante tener en cuenta que la asignación exacta de dinero puede variar dependiendo de las circunstancias y el acuerdo al que lleguen Verónica, Ana y Luis.

Answers
The complete square form of - 3x² + 33 = 48x is [x + 8]² = 75
Completing the square:
To do this, we add and subtract a constant term to the quadratic expression to make it a perfect square.
In this case, we use the formula x² + 2bx + b² = (x + b)² to rewrite the quadratic expression as a perfect square trinomial, and then we solved for the variable by isolating the squared term and taking the square root.
Here we have
- 3x² + 33 = 48x
Keep 'x' terms on one side and constant terms sides on another side
=> - 3x² - 48x = - 33
Divide by - 3 on both sides
=> -3(x² + 4x)/3 = - 33/3
=> x² + 16x = 11
Take half of the 'x' term and square it and add on both sides
=> x² + 2(8x) (x) + (8)² = 11 + (8)²
Which is in the form of x² + 2bx + b² = (x + b)²
=> [x + 8]² = 75

Answers
Given:
A prism has a base area of \(20\pi \) square units and a volume of \(120\pi\) cubic units.
To find:
The volume of the cylinder if the cylinder has the same base area and height.
Solution:
Volume of a prism is:
\(V=Bh\)
Where, B is the base area and h is the height of the prism.
The volume of cylinder is:
\(V=\pi r^2h\)
\(V=Bh\)
Where, r is the radius, h is the height of the cylinder and \(B=\pi r^2\) is the base area.
Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.
Hence the volume of the cylinder is \(120\pi\) cubic units.

A stone is dropped from the upper observation deck of a tower, 950 m above the ground. (Assume g = 9.8 m/s2.)
(a) Find the distance (in meters) of the stone above ground level at time t.
(b) How long does it take the stone to reach the ground? (Round your answer to two decimal places.)
(c) With what velocity does it strike the ground? (Round your answer to one decimal place.)
(d) If the stone is thrown downward with a speed of 8 m/s, how long does it take to reach the ground? (Round your answer to two decimal places.)
Answers
a) The distance of the stone above ground level at time t :
d(t)= -4.9t² + 950
b) It takes 13.92 seconds the stone to reach the ground
c) With 136.42 m/s velocity the stone strikes the ground.
d) If the stone is thrown downward with a speed of 8 m/s, it will take 13.13 seconds to reach the ground
Here, a stone is dropped from the upper observation deck of a tower, 950 m above the ground.
(a) the distance of the stone above ground level at time t would be,
d(t) = 0.5 (-9.8) t² + v(0) t + d(0)
= (-4.9)t² + 0t + 950
= -4.9t² + 950
(b) Now we find the time the stone takes to reach the ground.
i.e., the value of 't' when d = 0
Substituting d(t) = 0 in the above equation.
-4.9t² + 950 = 0
t² = (-950) / (-4.9)
t² = 193.88
t = 13.92 seconds
(c) We need to find the velocity the stone takes to strike the ground
i.e., the velocity when t = 13.92 seconds
v(t) = v(0) + gt
v(13.92) = 0 + (9.8)(13.92)
v = 136.42 m/s
(d) here, v(0) = -8 m/s
Velocity is negative because stone is being thrown downward.
d(t) = 0
(-4.9)t² + v(0) t + d(0) = 0
(-4.9)t² -8t + 950 = 0
Using the quadratic formula we solve above equation for,
t = -14.76, 13.13
We can disregard the negative solution
So, we get t = 13.13 seconds.
