Answer:
For this, we can use the formula
A=P(1+rt).
We know that A=1,000, r=4%=0.04 and t=5, so we can rearrange the formula for P to give
P=A1+rt,
and substituting the known quantities gives
P=1,0001+(0.04)(5)=1,0001.2≈$833.33
to the nearest cent. So, to the nearest dollar she must deposit $833.

Final answer:
Mary must deposit approximately $800 today into her account with a simple interest rate of 4% per year to have it worth $1,000 in 5 years.
Explanation:
To find out how much Mary must deposit today to have her account worth $1,000 in 5 years with a simple interest rate of 4% per year, we need to use the simple interest formula.
The formula for simple interest is I = P × r × t, where I is the interest, P is the principal amount (initial deposit), r is the annual interest rate (in decimal form), and t is the time in years.
The total amount A after t years is given by A = P + I. Since we know that A is $1,000, t is 5 years, and r is 0.04, we can rearrange the formula to solve for P:
In this case, the total interest earned in 5 years would be I = $1,000 - P. We can plug this into the interest formula: $1,000 - P = P × 0.04 × 5.
After simplifying, we'll find that P = $1,000 / (1 + 0.04 × 5), which calculates to P being approximately $800. So, Mary would need to deposit $800 today.

Step-by-step explanation:
A conical glass flower vase has a base that is 6 inches in diameter and a vase that holds approximately 113 in.³ of water what is the height of the vase?
To find the height of the vase, use the formula for the volume of a cone (V = (1/3)πr^2h) and solve for h. Given the base diameter and the volume of the vase, substitute the values into the formula to find the height. The height of the vase is approximately 4 inches.
Explanation:To find the height of the vase, we can use the formula for the volume of a cone which is V = (1/3)πr^2h, where V is the volume, r is the radius of the base, and h is the height. Given that the base of the vase has a diameter of 6 inches, the radius is half the diameter, which is 3 inches. We also know that the volume of the vase is approximately 113 in.³. We can substitute these values into the formula to find the height:
V = (1/3)π(3^2)h
113 = (1/3)π(9)h
113 = (3/3)π(9)h
113 = (π)(9)h
h = 113 / (π)(9)
h ≈ 4 inches
Therefore, the height of the vase is approximately 4 inches.
John and Liz are sharing a large pizza. John ate 1/3 of the pizza, and Liz ate 1/4 of the pizza. How much of the pizza is left?
Answer:
5/12
Step-by-step explanation:
Final answer:
After John ate 1/3 of the pizza and Liz ate 1/4, we convert these fractions to have a common denominator of 12, resulting in 4/12 + 3/12 = 7/12 eaten. Subtracting this from the whole gives us 5/12 of the pizza remaining.
Explanation:
John and Liz are sharing a large pizza. To determine how much of the pizza is left after John has eaten 1/3 and Liz has eaten 1/4, we need to add those fractions together and subtract the sum from the whole pizza, which is 1 (representing the entire pizza).
First, we find a common denominator, which in this case is 12, so we convert 1/3 to 4/12 and 1/4 to 3/12. Adding these fractions, we get 4/12 + 3/12 = 7/12.
Now we subtract the portion eaten from the whole pizza: 1 - 7/12 = 5/12 of the pizza is left.

Answer: D
Step-by-step explanation:
Paul's Current score is 42, x = paul's awaiting score
Paul's score has to be greater than 174
Current score plus awaiting score must be greater than 174
Answer:
d. 42 + p > 174
Step-by-step explanation:
Since Paul needs to score more than 174, the sign needs to be > and not ≥ because he does not want to equalize the score of 174.
Since he currently has a score of 42, he needs to add another score. Assuming the next score he needs is p,

Select all expressions that are equivalent to (2n+6)(n+3)
The expressions equivalent to (2n+6)(n+3) are Options C and F, E, F.
To determine which expressions are equivalent to (2n+6)(n+3), we can first expand this expression using the distributive property (also known as the FOIL method for binomials). This gives us:
[tex]2n \times n = 2n^2\\2n \times 3 = 6n\\6 \times n = 6n\\6 \times 3 = 18[/tex]Combining like terms (6n + 6n) gives us the expression [tex]2n^2 + 12n + 18[/tex]. Therefore, option C is equivalent to (2n+6)(n+3).
Looking at option F, [tex]2(n+3)^2[/tex] is indeed the same as (2n+6)(n+3) because if we expand[tex](n+3)^2[/tex], we get [tex]n^2 + 6n + 9[/tex], and multiplying the whole expression by 2 yields [tex]2n^2 + 12n + 18[/tex], which matches our previous result.
Option B, [tex]2n^2+6n+18[/tex], is not equivalent because it lacks the combined coefficient for the n terms that should be 12n rather than 6n. Option A is also correct. Option E, 2(n+3)(n+3), is just a different way of writing option F and is therefore equivalent. Option D, 12n+18, doesn't have the [tex]n^2[/tex] term, so it's not equivalent to the original expression.
Last year, 2376 people attended a summer music festival. This year the attendance was 2950. What was the percent of change in attendance to the nearest whole percent?
The percent change in attendance from last year to this year is approximately 24% after rounding to the nearest whole percent.
Explanation:To calculate the percent change in attendance, you can use the formula for percent change which is (new value - original value)/original value × 100%.
Last year, the attendance was 2376 people, and this year, it increased to 2950 people. Let's plug these numbers into the formula to find the percent change:
(2950 - 2376)/2376 × 100% = 574/2376 × 100% ≈ 24.16%.
When we round to the nearest whole percent, the percent change in attendance is approximately 24%.

You will get 4x^4 - 2x^3 + x^2 + 8x^3 - 4x^2 + 2x + 12x^2 -6x + 3
Then you need to combine like terms
And you will get the answer:
4x^4 + 6x^3 + 9x^2 - 4x + 3

j divided by 9 is 5.
Solve for j.
j=
Answer:
j = 45
Step-by-step explanation:
j/9 = 5
Multiply both sides by 9: j = 45
The required value of j will be 45 when j divided by 9 is 5.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
For example, 62÷31 = 2
To solve for j, we are trying to find the value of j that makes the equation "j / 9 = 5" true.
We can start by setting up the equation:
j / 9 = 5
This equation says that the result of dividing j by 9 is equal to 5.
To solve for j, we can multiply both sides of the equation by 9, the denominator of the fraction on the left-hand side:
j = 9 × 5
= 45
This shows that j = 45 is the solution to the equation. In other words, if we substitute 45 for j in the equation "j / 9 = 5", the equation becomes true:
45 / 9 = 5
Therefore, the value of j that makes the equation "j / 9 = 5" true is 45.

you pick a card at random what is p(3 or even)
The probability of drawing a 3 or an even card from a 52-card deck is calculated by adding the probability of drawing a 3 (1/13) and the probability of drawing an even card (5/13), resulting in a total probability of 6/13.
Explanation:In a standard 52-card deck, there are four 3's and twenty even cards (2, 4, 6, 8, 10 in each of four suits: hearts, diamonds, clubs, and spades). Therefore, the probability, p, of drawing a 3 or an even card is calculated by adding the probabilities of these two independent events.
First, calculate the probability of drawing a 3: P(3) = 4/52 = 1/13, as there are 4 cards with a 3 and 52 total cards.
Next, calculate the probability of drawing an even card: P(even) = 20/52 = 5/13, because there are twenty even cards in the deck.
Finally, add these probabilities: p(3 or even) = p(3) + p(even) = 1/13 + 5/13 = 6/13.
Note: We can add these probabilities directly because these are mutually exclusive events -- a card cannot simultaneously be a 3 and an even number.

A triangle with an area of 3 mm squared is dilated by a factor of 6. What is the area of the dilated triangle?
By definition, the area of a triangle is given by:
A = (1/2) * (b) * (h)
Where,
b: base
h: height
The area of the original triangle is 3 mm² and is dilated by a factor of 6. We have then
A = (1/2) * (6b) * (6h)
A = (1/2) * (b) * (h) * (6) * (6)
A = 3 * (6) * (6)
A = 108 mm²
answer
The area of the dilated triangle is 108 mm²
When a triangle with an original area of 3 mm squared is dilated by a factor of 6, the new area is found by multiplying the original area by the square of the dilation factor. This results in a new area of 108 mm squared.
The question asks about the effect of dilation on the area of a triangle. Specifically, it asks for the new area if a triangle with an original area of 3 mm² is dilated by a factor of 6. When dealing with dilation, the area of a shape changes by the square of the dilation factor. This means that if the dilation factor is 6, the new area will be 62 times the original area. This calculation can be performed as follows:
Original area = 3 mm²
Dilation factor = 6
New area = Original area × (Dilation factor)2 = 3 mm² × 62
New area = 3 mm² × 36 = 108 mm2
Therefore, the area of the dilated triangle is 108 mm²

The Tran family uses up a 1/2 gallon jug milk every 3 days. At what rate do the drink milk
Answer: 1/6 of a gallon per day
Step-by-step explanation: divide 1/2 by 3 and you get 1/6 .
The Tran family drinks milk at a rate of 1/6 gallon per day.
To find the rate at which the Tran family drinks milk, we can calculate the amount of milk consumed per day. First, determine how much milk they consume in 3 days: 1/2 gallon every 3 days. To find the daily consumption, divide the amount consumed in 3 days by 3:
\[\frac{1/2}{3} = \frac{1}{6} \text{ gallons per day}.\]
This means the Tran family drinks 1/6 of a gallon of milk every day. To express this rate in a more common unit, there are 128 ounces in a gallon. Therefore, the Tran family drinks:
\[\frac{1}{6} \times 128 = 21.\overline{3} \text{ ounces of milk per day}.\]
So, the Tran family drinks milk at a rate of approximately \(21.\overline{3}\) ounces per day.
