First, we have to find the interest / I. In the question is asked: '' he had earned $2975 in interest" so we know that the Interest/ I is $2,975.      $2,975= $17,500/P*r*2/t in years   (Substitute)                                                    $2,975= 35,000r                             (Multiply)                                               $2,975/35,000= $35,000r/$35,000 (Divide each side by $35,000)                          $2,975/$35,000=0.085                                                                                           Covert the decimal 0.085 to a percent.

2.5 is already to the nearest tenth. 3 is the the nearest whole number.
Here's an example:

The 4 is in the tenth spot, so you look at the next unit over, which in this example is the 7.
To round, the key is 4 and below, don't change, 5 and above, round up.
2.478382 would round to 2.5.
Here's another example just so it's clear:
For 3.7913, the 9 would make the 7 round up and the answer would be 3.8.
One unit after the decimal is the tenth place. Two units is the hundredth, three is the thousandth, and so on.

Equation: $157.30 × 10%

3. A family dines in a popular franchise restaurant. They plan to use a coupon that will give them a discount of 10% off of their total dinner bill, not including applicable sales tax or their server’s tip. The bill totals $157.30 before tax and tip. What is the new total after the server applies the 10% off coupon?

Answers

157.30*.10=
157.30-15.73=
$141.57
this is still without the tax and tip or assuming there is none because it doesn't say how much they want to tip or weather they are planning to tip at all. It also doesn't say the percent of tax.
Final answer:

To find the new total after a 10% discount on a $157.30 dinner bill, you multiply $157.30 by 0.10 to get the discount amount of $15.73. Then subtract the discount from the original bill to get the new total, which is $141.57.

Explanation:

To calculate the new total after applying a 10% discount to a $157.30 dinner bill, we first need to find the amount of the discount. To do this, we convert the percent to a decimal by dividing by 100. Therefore, 10% as a decimal is 0.10. Next, we multiply this decimal by the total bill amount.

$157.30 × 0.10 = $15.73

This value represents the amount of discount the family will receive. To find the new total, we simply subtract this discount from the original total bill amount.

$157.30 - $15.73 = $141.57

Thus, the new total after applying the 10% discount is $141.57.

A Table strategy needs an understanding of the problem. In addition to this strategy provides a clear vision of the problem.

Let's write it in a row, for the Cadillac. The second one for the Buick.

Plugging in values, here it is a Table like

Solve for n.

25n−3=5n+8
the n-3 and n+8 are powers

Answers

Final answer:

The equation 25n⁻³ = 5n⁺⁸ suggests an incorrect use of exponents, as no solution exists if we assume the bases should be the same. However, if the bases are 25 and 5, after simplifying, we find that the solution is n = 14.

Explanation:

To solve the equation 25n⁻³ = 5n⁺⁸, we need to use properties of exponents and logarithms. Here are the steps:

Assuming the bases are the same and only the exponents are different, equate the exponents: n - 3 = n + 8.This implies that no solution exists because once the bases are the same, the exponents on both sides must be equal for the equation to hold true, but here they are not.

Alternatively, if 25 and 5 are the bases, we can rewrite the equation as (52)n-3 = 5n+8, then applying properties of exponents gives us 52n-6 = 5n+8. Equating the exponents yields 2n - 6 = n + 8, which we can solve for n.

Subtract n from both sides: n - 6 = 8.Add 6 to both sides to isolate n: n = 14.

An “A” train leaves a subway station every 12 minutes. An “E” train leaves every 9 minutes. If both trains just left the station on parallel tracks, when will both leave the station together again?

A. in 108 minutes

B. in 36 minutes

C. in 72 minutes

D. in 24 minutes

Answers

B. In 36 minutes because 12×3=36 and 9×4=36 and this is the first number they share.

The A train and the E train will both leave the station together again in 36 minutes. Hence the correct option is B.

To find out when both the A train and the E train will leave the station together again, we need to calculate the Least Common Multiple (LCM) of their departure intervals, which are 12 minutes for the A train and 9 minutes for the E train. To find the LCM, we list multiples of each:

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108...

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108...

We can see that the common multiples of 9 and 12 are 36, 72, and 108. The smallest of these is 36 minutes, so that is the first time they will both leave the station together after initially departing at the same time.

Therefore, the correct answer is B. in 36 minutes.

Using this "order of operations" rules; we know that "multiplication" comes BEFORE "addition"; as such:

___________________________________________
By convention, when a variable has a coefficient other than "1", we usually write the term with the coefficient coming before the variable.

So, we can rewrite:

By convention; if we have a coefficient multiplied by a variable (symbolized with an "alphabet letter"), we simply write that coefficent, followed by the [variable symbolized with an "alphabet letter"]. By convention, the implication is that multiplication is inherent in these circumstances.

find the area and perimeter of the shape below. Help plzzz.

Find the area of each shape and add.Let's start with the first semi-circle(half-circle)
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle  which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²

Explain how you can use doubles when multiplying with4 to find 4x8?

Answers

using 4x6=24. double the factor four to get eight double the factor 24 to get 48
Final answer:

To multiply 4 by 8 using doubles, you double the numbers sequentially (4 to 8, 8 to 16, 16 to 32) to reach the desired result of 32. Moreover, when comparing the area of two squares, where one has a side length that is double the other, the area of the larger square is four times that of the smaller square.

Explanation:

To multiply 4 by 8 using doubles, you can double 4 to get 8, and then double 8 to get 16, and then double again to get 32. So essentially, you've found that 4 x 2 = 8, then took that result and found 8 x 2 = 16, and finally, you took that result and found 16 x 2 = 32, which is the same as 4 x 8. This method of doubling allows you to use simpler multiplication facts you may already know well, like multiplying by 2, to find the answer to more complicated problems.

In the context of scale factors and area comparisons, if you have a square with a side of 4 inches, and another square with sides twice as long (4 inches x 2 = 8 inches), the area of the second square would be 8 inches x 8 inches, which is 64 square inches. Compared to the first square, which has an area of 4 inches x 4 inches (16 square inches), the second square is larger by a factor of four (64 / 16 = 4). This demonstrates how the area increases by the square of the scale factor, not just by the scale factor itself.
