Answer:

Angie will need to save $2.50 for 8 more weeks to get $50

Step-by-step explanation:

Angie has already saved $30

12(2.5)=30

So since she needs $20 more you divide 20 by 2.5 and you get your answer.

20/2.5=8 weeks

Angie has saved $2.50 per week for the past 12 weeks, so she has saved a total of 2.50*12 = $30.00. To reach her goal of $50.00, she needs to save another 50-30 = $20.00. At her current rate of saving, it will take her 20/2.5 = 8 more weeks to reach her goal.

To calculate the total amount of money Angie has saved so far, we simply multiply the amount of money she saves each week by the number of weeks she has been saving.

In this case, Angie saves $2.50 per week and she has been saving for 12 weeks, so she has saved a total of $2.50 per week x 12 weeks = $30.

To calculate the amount of money Angie still needs to save, we simply subtract the amount of money she has saved so far from her goal amount.

In this case, Angie's goal amount is $50 and she has saved $30 so far, so she still needs to save $50 - $30 = $20.

To find out how many more weeks it will take Angie to reach her goal, we simply divide the amount of money she still needs to save by the amount of money she saves each week.

In this case, Angie still needs to save $20 and she saves $2.50 per week, so it will take her $20 / $2.50 per week = 8 weeks to reach her goal.

Therefore, it will take Angie 8 more weeks to save a total of $50.

If we put a negative sign in front of our function, it will flip the function over the x-axis.

Answer:

multiplying the function by -1.

Step-by-step explanation:

The ratio of the total number of players on the soccer team to the number of senior players is 1.41 to 1, found by dividing the total number of players (24) by the number of seniors (17).

The question is asking for the ratio of the total number of players on the team to the number of senior players. To get the total number of players, you should add the number of juniors and seniors together. This is, 7 juniors + 17 seniors = 24 total players. The ratio is then calculated as the total number of players divided by the number of seniors, which is, 24 total players ÷ 17 seniors. This simplifies to approximately 1.41 to 1.

Question 1:

For this case we have the following pattern of numbers:

24.3, 24, 23.7, 23.4

It can be seen that subtracting 0.3 from the first number of the pattern gives [tex]24.3-0.3 = 24\\[/tex]

Equally if we subtract 0.3 successively we obtain:

[tex]24-0.3 = 23.7\\\\23.7-0.3 = 23.4\\\\23.4-0.3 = 23.1\\\\23.1-0.3 = 22.8\\[/tex]

Thus, 0.3 must be subtracted from each term and the following numbers of the pattern shall be 23.1 and 22.8

Answer:

subtract 0.3 from each term

The next two numbers of the pattern are 23.1 and 22.8

Question 2:

For this case we have the following operation:

[tex]0.52 + 0.61 = 1.13\\\\1.13> 1\\[/tex]

We note that the sum is greater than 1

The sum of two hundredth decimals does not necessarily have to be greater than 1.

Therefore, the correct option is: the sum is greater than 1 because the sum shades more than one hundredths grid.

Answer:

Option C

Question 3:

For this case we have to:

[tex]a + b + c = 2\\[/tex]

Being a, b, c decimal numbers, one of them was 0.34. Suppose [tex]a = 0.34\\[/tex]

Thus: [tex]0.34 + b + c = 2\\[/tex]

We choose values ​​for b and c, in order to obtain the number 2 as a result of the sum. We can choose infinite values ​​so that equality is fulfilled

If[tex]b = 0.96[/tex] and

[tex]c = 0.7\\[/tex]

we have: [tex]0.34 + 0.96 + 0.7 = 2\\[/tex]

Thus, Holland can add to the sum [tex]b = 0.96[/tex] and [tex]c = 0.7\\[/tex]

Answer:

[tex]b = 0.96\\\\c = 0.7\\[/tex]

Question 4:

For this case we have the following subtraction:

[tex]3.5 - 2.46 = 1.16\\[/tex]

This operation is wrong, subtracting [tex]3.5-2.46[/tex] results in 1.04

Let's explain a model for Maysa:

We have the following expression

[tex]3.5 - 2.46\\[/tex]

Rewriting each number in expanded form we have:

[tex](3 + 0.5) - (2 + 0.46)\\[/tex]

Using the distributive property we have:

[tex](3 + 0.5) -2-0.46\\[/tex]

Using the associative property we have:

[tex](3-2) + (0.5-0.46)\\[/tex]

Performing each operation:

[tex]1 + 0.04 = 1.04\\[/tex]

Anwer:

The subtraction of Maysa is wrong, the correct answer is:

[tex]3.5 - 2.46 = 1.04[/tex]

Answer

Option B. Subtract 0.3 from each term.

Step-by-step explanation:

If you follow the pattern 24.3-24=0.3

similarly 24-23.7=0.3

23.7-23.4=0.3

Conclusion : We will subtract 0.3 every time in order to get the new number.

We use an exponent law here.

Since 1/xⁿ = x⁻ⁿ for positive number a and real number n, it follows that

  1 / 9⁴ = 9⁻⁴

The expression 1/9^4 can be changed to an expression using a negative exponent by applying the negative exponent rule, resulting in 9^-4.

To change the expression 1/9^4 to one using a negative exponent, we can apply the property of negative exponents which states that x^-n = 1/x^n. The expression 1/9^4 can thus be written as 9^-4 because we are in essence taking the inverse of 9 raised to the fourth power.

Find the cost for one ticket for the science center.

36.75 ÷ 3 = 12.25

Multiply the product with 12 to get the cost of 12 tickets.

12.25 × 12 = 147

Find the cost of 1 zoo ticket.

51 ÷ 4 = 12.75

Find the cost of 12 tickets by multiplying the product and 12

12.75 × 12 = $153

12 Science Center Tickets cost $147

12 zoo tickets cost $153

The Zoo costs more than the Science Center.

To find out how much more the Zoo costed, subtract 147 from 153.

153 - 147 = 6

The zoo only costs $6 more for 12 students.

So, you're answers are Zoo and $6

Linear equations are an equation between two variables that makes a straight line on a graph. You need to find the value of x or y. You can usually substitute numbers in for x or y until you get what they're equaling.

A) x=1/2

You can get this by first finding the like terms. In this case it would look like 4x-2=0. Then you'd move the constant to the right to get 4x=2. Then just divide both sides by 4 to get 1/2.

Ur answer is 1,229

Step-by-step explanation:

Ok it’s simple u start with 1196 then u just need to add add and subtract as so

Monday: 1196+ 18=1,214

Tuesday: 1,214+31=1,245

Wednesday: 1,245-5=1,240

Thursday: 1,240+27=1,267

Friday: 1,267-38=1,229

So therefore it is 1,229

Answer: It ended at 1229 on Friday.

Step-by-step explanation:

Given : During one week, the stock market did the following: Monday rose 18 points, Tuesday rose 31 points, Wednesday dropped 5 points, Thursday rose 27 points and Friday dropped 38 points.

In integers , we use (+) for rise in quantity and (-) for drop in quantity.

If it started out at 1196 on Monday, then

On Friday = 1196 +18 +31-5+27-38 = 1229   [we use (+) for rise in quantity and (-) for drop ]

Hence, it ended at 1229 on Friday.

To find the lengths of the sides of the triangle, we set up an equation using the given perimeter and the relationships between the sides. Solving the equation gives us the length of each side.

To find the lengths of the sides of the triangle when given the perimeter and relationships between the lengths of the sides, we can use algebra to set up a system of equations. Let's denote side b as x centimeters. According to the problem, side a is 3 centimeters longer than side b, so a can be represented as x + 3 centimeters. Side c is 1 centimeter shorter than twice side b, which gives us c as 2x - 1 centimeters.

The perimeter of the triangle is the sum of its sides, so:

x + (x + 3) + (2x - 1) = 26

Solving this equation gives us x, from which we can determine the lengths of sides a and c as well.
