Alessa had 50 in her account. she then received four $-25 charges to her account. what is the new balance of her account
The new balance in her account will be $150.
We have Alessa.
We have to find the new balance of her account after receiving four $-25 charges.
What is Account ?Account is referred here as a bank account used for the purpose of saving money by the people.
According to the question -
Initial money in Alessa's account = $50
Total money received = $25 x 4 = $100
Therefore, the new balance in her account will be -
$50 + $25 x 4 = $150
Hence, the new balance in her account will be $150.

the age distribution of a population (relative proportions of people of different ages) is not important when considering the growth rate of that population.
It is False to state that the age distribution of a population is not important when considering the growth rate of that population.
What is the growth rate of a population?Population growth is the rise in the number of inhabitants in a population or scattered group and it is usually stated in percentage.
Researchers often focus on four primary elements when forecasting changes in population size:
Birth rates,Death rates (life expectancy),The beginning age profile of the population (i.e. elderly or relatively young individuals), and Migration.Other factors include:
Economic development Social and cultural factorsEducation, etcAge distribution and statistics allow the pace of population growth to rise or decline as it is linked to the level of economic development of a population. a fast-expanding country's population has a pyramid-shaped age structure, with a higher share of younger people of reproductive age.
Therefore, we can conclude that it is False to state that the age distribution of a population is not important when considering the growth rate of that population.

As captain of the cheer team Lily is choreographing a routine for a competition. The minimum allowable length for a routine is 3 minutes and the maximum allowable length for a routine is 5 minutes. Write an absolute value for which the two solutions are the minimum and maximum allowable lengths.
Lily, the cheer team's captain, is putting together a performance for a tournament. A routine may be no less than 3 minutes in length and no more than 5 minutes in total. For which the two solutions are the shortest and longest permitted lengths, write an absolute value.
The absolute value for 3 is 3 .
The absolute value for 5 is 5.
The two solutions are the shortest and longest permitted lengths, The absolute value |2x−5|+|2x−3|=2
Absolute value is the non-negative value of a real number x, independent of its sign, is its absolute value (or modulus), | x |.
For example, 5 has an absolute value of 5, and -5 has a value of 5. Another way to think about a number's absolute value is as its distance from zero on the real number line. In addition, the distance between two real numbers is the absolute value of their difference.
Given that,
A routine may be no less than 3 minutes in length and no more than 5 minutes in total.
By absolute value equation
we can get 2x−5|+|2x−3|=m
By solving we get 2 m values they are,
m={-8,2}
Here, -8 we can take but the answer will be in decimal soo we take 2.
|2x−5|+|2x−3|=2
We get
[tex]|4x-8|=2\\|x-2|=1\\|x|=3\\[/tex]
If we take 2x =y
|y−5|+|y−3|=2
[tex]|2y-8|=2\\|y-4|=1\\|y|=5[/tex]
Therefore,
The absolute value for 3 is 3 .
The absolute value for 5 is 5.

A ribbon is 4m long.how many pieces each 30cm long can be cut from the ribbon
Answer: 13 pieces
Step-by-step explanation:
4 m * 100 cm/1 m=
4 * 100/1=
4*100=400 cm.
400/30=
(10+390)/30=
10/30 + 390/30=
1/3 + 13 ==> 13 pieces
Work Shown:
1 meter = 100 cm
4 meters = 400 cm
400/30 = 13.33 approximately
That rounds down to 13
You'll have 400-13*30 = 400-390 = 10 cm of ribbon leftover.

154 times 63 = 462. 462 + question mark = blank
The missing value is
A. 904
B.9040
C.9240
Answer:
The answer is C
Step-by-step explanation:
The first step is to multiply 154 and 63 to find the product. The product of those two numbers is 9702.
So the the equation looks like...
462+ Blank = 9702
The easiest thing to do here is subtract 462 from both sides. So 9702-462 which would equal 9240.
So we'll say that the blank is x so now the equation says...
x = 9240

14. Wisco's winter carnival is coming up, and Mr. Raymond is in charge of ordering the craft kits again. He knows he ordered 13 boxes of snow globe kits last year but can't remember how many kits came in a box. He checks the records and finds that the school used 172 of the snow globe kits last year and had 10 left over after the event. How many snow globe kits come in each box?
Answer:
169
Step-by-step explanation:
Answer:
Assume x to be the number of snow globe kits that come in each box.
Then the equation that describes the given situation is
13x - 10 = 172
13x = 182
x = 14
So, the number of snow globe kits that come in each box is 14.
let a be the event that the sum of the faces showing is 6 and let b be the event that the face showing on one die is twice the face showing on the other die.
PABc = 3/36
PABc = 1/12.
Two dice are tossed.
Assume that each possible outcome has 1/36.
Let A be the event the probability of getting some of the faces showing is 6.
A = 1,5,5,12,44,23,3
Let B be the event that the face showing one die is twice on the other.
That is,
B =1,22,12,44,23,66,3
There are 36-6=30 events in Bc
However, A and Bc will only be having 3 pairs together = 1,55,13,3
Therefore,
PABc = 3/36
PABc = 1/12.
How many outcomes are possible for the sum of the faces showing?
There are countless outcomes that could occur. The sum of the faces shown has an endless number of outcomes. This is due to the fact that there are an endless number of ways to flip a coin, which will produce various combinations on the faces that are displayed. The sum of the faces and the tails has an endless number of outcomes. There are only two outcomes that can occur while tossing a coin because the total number of outcomes is always even.

It is always ranges from 0 to 1 where 0 is minimum value and 1 is maximum value of probability.
Formula for probability is :

Will the side pieces of the frame be parallel?_____________________
How do you know?
If a carpenter cut the top section of a window frame with a 40º angle on each end. The side pieces each have a 50º angle cut at their top ends, as shown. Yes the side pieces of the frame will be parallel. How i know is that both side are equal or parallel.
ParallelThe interior angles are the same in measure and the sum of the interior angles have to be 180°.
The two side pieces on both the right and left hand side are equal in measure. The sides can be parallel only if the sum of both side angles is equal to 180°
Hence,
One side of the interior angle=40º+50º
One side of the interior angle=90°
Both side of the interior angle=90°+90°
Both side of the interior angle=180°
Hence,
180°=180°, the sides are parallel

A rental car agency charges $180 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $382.50?
Answer:
810
Step-by-step explanation:
382.50-180= 202.5
202.5 / 0.25= 810
Hope this helps!
Answer:

$180 a week is the fixed cost so we subtract this first.
($382.50 - $180 = $202.50)
The number left is the amount of dollars charged per mile.
So if we divide this number by $0.25, we get how many miles travelled.
($202.50 ÷ $0.25 = 810 miles)
