find the surface area of the figure

The height of the oblique triangular pyramid is 15 units if the base area of 15 square units and a volume of 20 cubic units.

Volume is defined as a three-dimensional space enclosed by an object or thing.

We know the volume of an oblique triangular pyramid is given by:

V = 1/3b h

Where b is the area of the base and h is the height of the pyramid.

We have b = 15 square units and V = 15 cubic units.

h = 4 units

V = 1/3 x 15 x 4

V = 20

Thus, the height of the oblique triangular pyramid is 15 units if the base area of 15 square units and the volume of 20 cubic units.

Step-by-step explanation:

We can make 30 non congruent rectangles.

There are several approaches to this issue, but one is to count the number of rectangles of various sizes.
A 4x4 geoboard can contain the following:

1 rectangle is of size = 4x4

4 rectangles are of size = 3x3

9 rectangles are of size = 2x2

16 rectangles are of size = 1x1

Use the following formula to determine the number of rectangles can be created within given these dimensions:

(Number of rows + 1 - Height of rectangle) (Number of columns + 1 - width of the rectangle)

For instance, we have (4 + 1 - 2) while counting the number of 2x2 rectangles. × (4 + 1 - 2) = 3 × 3 = 9

The total number of rectangles can be calculated as follows:

1 + 4 + 9 + 16 = 30.

So, on a 4x4 geoboard, there are 30 rectangles that can be created, none of which can be congruent.

Answer:

$17,184.80.

Step-by-step explanation:

Jessica's loan for home renovations is for $17,100 for 54 days. The bank charges simple interest at an annual rate of 9.65%. To calculate the interest charged, first, we need to find the daily interest rate, which is 9.65% divided by 365, resulting in 0.0264%. The total interest charged on the loan is $84.80, which is calculated by multiplying the daily interest rate by the loan amount and the number of days (0.000264 x $17,100 x 54). Therefore, Jessica's total amount owed to the bank at the end of the loan term is $17,184.80.

Answer:

x = 1

y = -5

Step-by-step explanation:

x - 3y = 16

-5x + 3y = -20

Combine the equations

-4x = -4

x = 1

Now put 1 in for x and solve for y

1 - 3y = 16

-3y = 15

y = -5

Let's Check

1 - 3(-5) = 16

1 + 15 = 16

16 = 16

SO, x = 1 and y = -5 is the correct answer.

The size of the shadow cast by the actual truck as required to be determined in the task content is; Choice A; 36 square feet.

It follows from the task content that the size of the actual truck is to be determined given the model size and the model scale.

Since the model scale is 1 to 54 and the model casts a shadow of 8 square inches; we have that;

1 / 54 = 8 / x where x is the size of the shadow cats by the actual truck.

There; x = 54 × 8 = 432 square inches.

However, recall that 12 inch units represents a feet; therefore, we have that;

x = 432 / 12

x = 36 square feet.

Consequently, the size of the actual shadow cast by the truck is; Choice A; 36 square feet.

The table shows a dartboard with 10 slices numbered from 1 to 10. X is the event that the dart lands on a grey slice, and not X is the event that it lands on a non-grey slice. The probability of X is 5/10 or 0.5. The probability of not X is 1 - P(X) or 0.5.

The dartboard has 10 equally sized slices numbered from 1 to 10, some of which are grey and some are white. X is the event that the dart lands on a grey slice and P(X) is the probability of X. The event not X is the event that the dart lands on a slice that is not grey, and P(not X) is the probability of not X.

The table asks to check the outcomes contained in the event and enter the probability of the event in the last column. In the table, the outcomes are given as 1 to 10, and X represents the event that the dart lands on a grey slice. The probability of X, P(X), is given as 5/10 or 0.5. The event not X represents the event that the dart lands on a slice that is not grey. Since there are 5 white slices, P(not X) = 5/10 or 0.5.

We need to subtract P(X) from 1 to get P(not X), since they are complementary events. Thus, P(not X) = 1 - P(X). Substituting the value of P(X) from part (a), we get P(not X) = 1 - 0.5 = 0.5.

The sum of magnitude of u + v is 15.99.

The  magnitude or size of a mathematical object is described as a property which determines whether the object is larger or smaller than other objects of the same kind.

Given that, magnitude of u =  5

Magnitude of v = 11

The angle between them i= 40°

we represent u and v in vector form,

u = 5 ( cos 40° i + sin 40° j ) = 3.83 i + 3.21 j

v = 11 ( cos 40° i + sin 40° j ) = 8.42 i + 7.07 j

The sum of two vectors is given by

u + v = 3.83 i + 3.21 j +  8.42 i + 7.07 j

u + v = 12.25 i + 10.28 j

Magnitude of u + v = √(12.25²+10.28²)

The y-intercept represents the base price of $200 for airfare from NYC.

The slope represent a cost of $0.30 cents per mile traveled.

According to the equation given, someone who traveled 2000 miles from NYC would pay $800 for their fare.

According to the equation given, someone who paid $500 for airfare from NYC would have traveled 1000 miles.

If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y = 50 + 0.30x.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + c

Where:

Based on the information provided about this trip, a linear equation that models the situation is given by;

y = mx + c

y = 0.30x + 200

When x = 2000, the price of airfare (y) is given by;

y = 0.30(2000) + 200 = $800.

When y = 500, the distance traveled (x) is given by;

Answer: 62 words/ 1 minute

Step-by-step explanation:

Example: $35 for 5lbs of flour. 35/5 in the simplest form is 7/1; therefore it is the unit rate.

Out of Maria's total expenses, the proportion of expenses for her car would be 0. 57 .

To find the proportion, the formula would be :

Maria total car expenses = $ 290. 02

Maria total expenses for the month =  $ 507. 59

The proportion of expenses for her car would be :

= 290. 02 / 507. 59 x 100 %

The ordered pair that shows an equivalent ratio of hours to miles is (1, 12) and Jing will complete a 60-mile trip in approximately 5 hours.

To find an equivalent ratio of hours to miles, we need to divide the number of miles by the number of hours.

For example, for the first 4 hours of the bike trip, Jing rode 48 miles, which is equivalent to a rate of 12/4 = 3 miles per hour.

Since Jing rode 60 miles in the first 4 hours of the trip, we can use this rate to find the time it takes her to ride 60 miles.

We can set up a proportion:

12 miles / 1 hours = 60 miles / x hours

Cross-multiplying, we get:

12x = 60

Dividing by 12, we get:

x = 60/12

x = 5

Answer:

Each package will contain 1/2 pound of meat.

Step-by-step explanation:

To divide 8 1/2 pounds of hamburger meat into 17 equal packages using fractions, you need to divide the total weight by the number of packages:

First, convert the mixed number 8 1/2 to an improper fraction:

(8 * 2) + 1 = 16 + 1 = 17

So, 8 1/2 = 17/2

Now, divide 17/2 pounds by 17 packages. Since division is the same as multiplying by the reciprocal, we'll multiply by the reciprocal of 17, which is 1/17:

(17/2) * (1/17)

Multiply the numerators together (17 * 1 = 17) and the denominators together (2 * 17 = 34):

17/34

Simplify the fraction by dividing the numerator and the denominator by their greatest common divisor (17):

17 ÷ 17 = 1

34 ÷ 17 = 2

So, the simplified fraction is 1/2.

If Marco completely filled a box with 36 unit cubes with no gaps or overlap, then the box must have a volume of 36 cubic units.

The box could have different dimensions depending on how the cubes are arranged. For example, the box could be a cube with side length 3 units, since 3 x 3 x 3 = 27. Then, Marco could add another layer of 3 x 3 cubes on top of the first layer, giving a total of 3 x 3 x 4 = 36 cubes.

Alternatively, the box could have dimensions 6 x 1 x 6, since 6 x 1 x 6 = 36. This box would have two layers of 6 x 6 cubes stacked on top of each other.

There are many other possible dimensions for the box, but all of them must have a volume of 36 cubic units to accommodate the 36 unit cubes with no gaps or overlap.
