Find the area of the parallelogram 9.9in 5.5in

Answers

Answer:

54.45 in²

Step-by-step explanation:

Let the base and height be 9.9 inches and 5.5 inches respectively.

Formula;

Area of parallelogram = Base × Height

Substitute the base and the height in the formula:

⇒ Area of parallelogram = Base × Height⇒ Area of parallelogram = 9.9 × 5.5

Evaluate the area of the parallelogram:

⇒ Area of parallelogram = 9.9 in × 5.5 in⇒ Area of parallelogram = 54.45 in²

Answer:

54.45 in²

Step-by-step explanation:

Formula

Area of a parallelogram = base × height

If you turn the parallelogram so that the sides that measure 9.9in are the base, you will see that 5.5in is the height (refer to the attached diagram).  Therefore, we can use the formula with these values to calculate the area.

Given:

base = 9.9 inheight - 5.5 in

⇒ area = 9.9 × 5.5 = 54.45 in²

45°
OA. 4
B. 2
OC. 412
OD. 212

Answers

Answer:

D

Step-by-step explanation:

use the sine or cosine ratio in the right triangle.

using the sine ratio and the exact value

sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )

2x = 4[tex]\sqrt{2}[/tex] ( divide both sides by 2 )

x = 2[tex]\sqrt{2}[/tex]

The value of x is 2√2.

Hence the correct option is D.

Given that a right triangle with acute angles 45° each, and hypotenuse is 4 units,

we need to find the length of the perpendicular,

In a right triangle, the length of the perpendicular (also known as the altitude) can be found using trigonometric ratios.

In this case, since we have an angle of 45°, we can use the sine or cosine function.

Let's use the sine function to find the length of the perpendicular:

sin(45°) = opposite / hypotenuse

sin(45°) = perpendicular / 4

1/√2 = perpendicular / 4

perpendicular = 4/√2

perpendicular = 2√2

Hence the value of x is 2√2.

what is the 41st term of 8,17,26

Answers

Answer:

368

Step-by-step explanation:

We can see that 9 is being added to each term.

Thus, we obtain the following rule:

8 + 9(x - 1)

To make this easier, let's simplify the rule.

⇒ 8 + 9(x - 1)⇒ 8 + 9x - 9⇒ 9(x) - 1

Substitute 41 as "x" to obtain the 41st term:

⇒ 9(41) - 1⇒ 368

The value of 41st term of sequence 8, 17, 26 is,

⇒ 368

What is Arithmetic sequence?

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

Given that;

The sequence is,

⇒ 8, 17, 26.

Now, The common difference is,

⇒ d = 17 - 8 = 9

⇒ d = 26 - 17 = 9

Thus, The sequence is in arithmetic.

Hence, The value of 41st term of sequence 8, 17, 26 is,

⇒ a + (n - 1)d

⇒ 8 + (41 - 1) 9

⇒ 8 + 369 - 9

⇒ 8 + 360

⇒ 368

Thus, The value of 41st term of sequence 8, 17, 26 is,

⇒ 368

The Davis family purchased a house last year. They put $20,000 towards a down payment and took out a $265,000 mortgage. Because it was a new home, all the repairs and maintenance were covered under the builder’s warranty, but the Davises want to budget this coming year for unexpected expenses. When estimating costs for home repair and maintenance, a good estimate is to budget 1% of the purchase price of a house. What would be a good yearly estimate of repairs and maintenance for the Davis family’s home? a. $28,500 b. $2,650 c. $2,850 d. $200

I'm not very good with percentages, so this may be incorrect, but 1 ℅ of the total purchase price would be 2850 because 1 ℅ is essential 0.01 x 285,000. 285,000 would be adding the down-payment to the mortgage.

Step-by-step explanation:

opposite angles are congruent so (3x+30)=(4x+14)

Solve for x

x=16

adjacent sides are supplementary so insert x in both equations just to make sure it is correct and you get 78

so 3y=78 and 6z=78

solve for y and z

y=26, z=13

4. Find the surface area of the triangular prism:
5 ft
5 ft
3 ft
14 ft
8 ft
Shows work please

Answers

Answer:

  276 ft²

Step-by-step explanation:

The total surface area of a prism is the sum of its lateral area and the area of its bases. Here, the bases are two triangles, and the area of the sides is that of three rectangles.

base area

The area of a triangle is given by the formula ...

  A = 1/2bh . . . . where b is the base of the triangle, h is its height

We have two identical triangles, so their total area will be ...

  A = 2(1/2bh) = bh = (8 ft)(3 ft) = 24 ft²

lateral area

The sides of the prism are rectangles, all with the same length: 14 ft. Their total area will be that length multiplied by the total of the rectangle widths. That total is the same as the perimeter of the triangular base:

  P = 5 ft + 5 ft + 8 ft = 18 ft

Then the lateral area is ...

  lateral area = Ph = (18 ft)(14 ft) = 252 ft²

total area

The sum of the base area and lateral area is ...

  (24 ft²) +(252 ft²) = 276 ft² . . . . area of the triangular prism
