What is the value of the expression 2 + 3/4 (1 1/2 + 3.8)

Answer:

15degrees

Explanation:

Using the theorem;

Angle in the same segment of the circle are equal hence;

mGiven that mSubstitute

3x = 45

Answer:

340 baseball cards

Step-by-step explanation:

You sold 20% of 420, therefore,

425 - 20% * 425 = 340

You have 340 baseball cards left.

The price of the car after the 15% markup is $8,280

A markup is the amount by which a seller increases the price of a product above its cost, in order to make a profit. In this case, we're told that the seller, Hank, bought the car for $7,200 and wants to sell it on his used car lot for a higher price.

To find the new price of the car after the markup, we need to add 15% of the original price to the original price. The formula for finding the new price with a markup is

New Price = Original Price + Markup

We're given the original price of the car as $7,200, so we can plug that into the formula

New Price = $7,200 + Markup

To find the markup, we need to calculate 15% of $7,200. We can do this by multiplying 0.15 (which is 15% written as a decimal) by $7,200

Markup = 0.15 x $7,200

Markup = $1,080

Now we can substitute the markup value into our formula

New Price = $7,200 + $1,080

New Price = $8,280

Answer:

The numbers are 30 and 128

Step-by-step explanation:

Let's call the smaller number S (for smaller) and the larger L (for larger).

"The larger of two numbers is eight more than four times the smaller number"

translates to

L = 4 * S + 8

"The larger number is also thirty-eight more than three times the smaller number"

translates to

L = 3 * S + 38

So we have 2 equations with 2 unknown variables - we can solve this.

4 * S + 8 = 3 * S + 38     // subtract 3*S from both sides

S + 8 = 38

S = 30

We have the smaller number, now for the larger

L = 4 * S + 8 = 4 * 30 + 8 = 128

or

L = 3 * S + 38 = 3 * 30 + 38 = 128

Rhombuses are a particular sort of quadrilateral in Euclidean geometry. It is a unique instance of a parallelogram in which the diagonals meet at a 90-degree angle and all sides are equal. This is a rhombus' fundamental characteristic. A rhombus has a diamond-shaped form.

Therefore,

Because it is in diamond shape,'

M<QOR= 90°

M<OQR + M<ORQ =90°.

x= M<ORQ = 90° - 37°

The height of the all after 2 secs is 86 feet

Given the height in feet above the ground was given by the following function h(t) = -16t^2 + 75t

where:

t is the number of seconds since the ball was punted.

If the value of t = 2s, hence;

h(t) = -16t^2 + 75t

h(2) = -16(2)^2 + 75(2)

h(2) = -64 + 150
h(2) = 86

Answer:

$13.85

Step-by-step explanation:

If the textbook decreases by 11% per year, this means it will be 89% of the previous year's value since 100% - 11% = 89%

89% in decimal form = 89/100 = 0.89

Therefore, the exponential function is:

\(y = 63 \cdot 0.89^x\), where \(x\) is the number of years

So when \(x=13\),  

\(y = 63 \cdot 0.89^{13}=13.84875..=13.85\)

Answer:

433345344 Answer

Step-by-step explanation:

Let's calculate the products and check if they indeed have the same value:

Product of 32 and 46:

32 * 46 = 1,472

Reverse the digits of 23 and 64:

23 * 64 = 1,472

As you mentioned, the products are the same. This phenomenon is not unique to this particular pair of numbers. In fact, it occurs with any pair of two-digit numbers whose digits, when reversed, are the same as the product of the original numbers.

To find two other pairs of two-digit numbers that have this property, we can explore a few examples:

Product of 13 and 62:

13 * 62 = 806

Reversed digits: 31 * 26 = 806

Product of 17 and 83:

17 * 83 = 1,411

Reversed digits: 71 * 38 = 1,411

As for determining if a given pair of two-digit numbers will have this property without actually performing the multiplication, there is a simple rule. For any pair of two-digit numbers (AB and CD), if the sum of A and D equals the sum of B and C, then the products of the original and reversed digits will be the same.

For example, let's consider the pair 25 and 79:

A = 2, B = 5, C = 7, D = 9

The sum of A and D is 2 + 9 = 11, and the sum of B and C is 5 + 7 = 12. Since the sums are not equal (11 ≠ 12), we can determine that the products of the original and reversed digits will not be the same for this pair.

Therefore, by checking the sums of the digits in the two-digit numbers, we can determine whether they will have the property of the products being the same when digits are reversed.

Step-by-step explanation:

To graph the equation y = (1/2)x, we can plot points on a coordinate plane and connect them to create a straight line. Here's how to do it:

1. Choose some x-values to evaluate the equation. Let's select a range of x-values, such as -10, -5, 0, 5, and 10.

2. Substitute each x-value into the equation to find the corresponding y-values. For example:

  - For x = -10, y = (1/2)(-10) = -5

  - For x = -5, y = (1/2)(-5) = -2.5

  - For x = 0, y = (1/2)(0) = 0

  - For x = 5, y = (1/2)(5) = 2.5

  - For x = 10, y = (1/2)(10) = 5

3. Plot the points (x, y) on a graph. In this case, the points would be:

  (-10, -5), (-5, -2.5), (0, 0), (5, 2.5), (10, 5)

4. Connect the plotted points with a straight line. The line should pass through all the points.

The resulting graph is a straight line with a slope of 1/2, passing through the origin (0, 0), and extending infinitely in both directions.

Step-by-step explanation:

Just trust me, I just really don't wanna explain it.

The parametric equations for the line segment from (9, 2, 1) to (6, 4, −3) using the parameter t are x(t) = 9 - 3t ,y(t) = 2 + 2t ,z(t) = 1 - 4t

We can use the point-slope form of a line to write the parametric equations

These equations represent the x, y, and z coordinates of a point on the line segment at a given value of t. By plugging in different values of t, we can find different points along the line segment.

To derive these equations, we start by finding the vector that goes from (9, 2, 1) to (6, 4, −3). This vector is:

<6 - 9, 4 - 2, -3 - 1> = <-3, 2, -4>

Next, we find the direction vector by dividing this vector by the length of the line segment:

d = <-3, 2, -4> / sqrt((-3)² + 2² + (-4)²) = <-3/7, 2/7, -4/7>

Step-by-step explanation:

To get no solution, you want to get rid of x and leave an incorrect equation.

In this case, we will use 1/3x.

1/3x + 2 = 1/3x - 3

We subtract 1/3x on both sides. This will cause the 1/3x's to cancel out.

1/3x - 1/3x + 2 = 1/3x - 1/3x - 3

2 ≠ -3

As we know, 2 is not 3. Therefore, there is no solution if 1/3x is used.
