Answer:

The area of the triangle is 351cm^2.

Step-by-step explanation:

To find the area of a triangle, the formula is (1/2) x base x height. In this case, the height would be a line that cuts straight through the center of the triangle. However, this height is not given to us. We can still find it through Pythagoras' Theorem though.

Let A be the tip of the triangle, and B and C be the points on either side of the triangle. Assuming an imaginary line that cuts the triangle in a symmetrical half, let T be the point at the end of the line, directly below point A.

Using Pythagoras' Theorem,

AB^2 = AT^2 + TB^2

AT^2 = AB^2 - TB^2

AT^2 = 30^2 - (26/2)^2

AT^2 = 30^2 - 13^2

AT =

[tex] \sqrt{ {30}^{2} - {13}^{2} } [/tex]

AT = 27.0370116692

So the length of AT is our height. We can now find the area of the triangle.

Area of triangle = (1/2) x 26cm x AT

Area of triangle = 351.4811516996

Area of triangle = 351cm^2 (To 3s.f.)

Answer:

38 degrees.

Step-by-step explanation:

Using the Cosine Rule:

11^2 = 10^2 + 17^2 - 2*10*17cos A

cos A = (11^2 - 10^2 - 17^2) / (-2*10*17)

cos A = -268/-340 = 0.788235

m < A =  37.979

Explanation: There are four equal sections, one of which is red. So the probability of landing in the red space is 1/4.

Answer:

$110,080

Step-by-step explanation:

This is an arithmetic sequence because each new term is obtained by adding $5000 to the preivous term.

The general formula for such an arithmetic series is

a(n) = $80,000 + ($5,000)(n - 1)

and so in his 23rd year Jason would make

a(23) = $80,000 + ($5,000)(23 - 1), or

$110,080

Answer:

$110,080 is the answer

Answer:

StartFraction 1 Over 45 EndFraction of a yard

Step-by-step explanation:

Length of the wooden dowel rod = 8/15 of a yard

Number of pieces = 24

What is the length of each piece of dowel rod?

Length of each piece of dowel rod = Total length of wooden dowel rod / number of pieces

= 8/15 ÷ 24

= 8/15 × 1/24

= (8*1) / (15*24)

= 8/360

= 1/45

Length of each piece of dowel rod = 1/45 of a yard

Answer:

number 1:area is 30 , perimeter is 22

number 2:area is 450 perimeter is 29

Step-by-step explanation:

Answer:

1 = 30, 22. 2 = 45, 33.

Step-by-step explanation:

For step 1, multiply the numbers to get the area, then double them and add them all to get the perimeter.

For step 2, multiply the two sets of numbers, 5 and 3, and 6 and 5, and add them. For the perimeter do the same as step 1.

Answer:92.84

Step-by-step explanation: 39+27+13.5+13.5 because the two sides are longer than 12

The perimeter of the trapezium is 143.94 ft.

We have,

The perimeter of an isosceles trapezium can be found by adding the lengths of all four sides.

In this case, the trapezium has height = 12 ft and parallel sides of length 27 ft and 39 ft.

To find the length of the non-parallel sides we can use the Pythagorean theorem:

a² = (39 - 27/2)² + 12²

a² = 1440

a ≈ 37.95 ft

Therefore,

The perimeter of the trapezium is:

P = 27 + 39 + 2a

P ≈ 27 + 39 + 2(37.95)

P ≈ 143.9 ft

Rounding to the nearest hundredth place,

we get P ≈ 143.94 ft.

Thus,

The perimeter of the trapezium is 143.94 ft.

Answer:

Total cost= $39

Step-by-step explanation:

Giving the following information:

At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75.

First, we will establish the total cost formula:

Total cost= 5.5p + 3.75d

p= number of bags of popcorn

d= number of drinks

Now, for 3 bags and 6 drinks:

Total cost= 5.5*3 + 3.75*6

Total cost= $39

Answer:

x = -13

Step-by-step explanation:

Step 1: Rearrange terms

9-2x=35

-2x+9=35

Step 2: Subtract from both sides of the equation

-2x+9-9=35-9

Step 3: Simplify

-2x+0=26

-2x=26

Step 4: Divide both sides of the equation by the same term

-2x/-2 = 26/-2

Step 5: Simplify

x = 26/-2

x=-13

104 in squared

Answer:

104ft²

Step-by-step explanation:

formula for area of a triangle = [tex]A=\frac{bh}{2}[/tex]

where b = base length and h = height

The triangle shown has a base length of 16 ft and a height of 13 ft

Using this information we plug in the values into the formula

[tex]A=\frac{16*13}{2}\\16*13=208\\\frac{208}{2} =104\\A=104ft^2[/tex]

Answer:

10000

Step-by-step explanation:

Let the number = x

Square root of x divided by 5 equals 20

√x / 5 = 20

Using cross multiplication

√x = 20 * 5

√x = 100

Take the square of both sides

(√x)² = 100²

x = 10000

Therefore, the number is 10000

Answer: it should be 9.2%

Step-by-step explanation:

The  percentage of people in the [tex]41 - 50[/tex] age group and favored the Do-It-Yourself books will be [tex]9.2\%[/tex] .

Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]"\%"[/tex] .

Percentage [tex]=\frac{Obtained\ Number}{Total\ Number} *100[/tex]

We have,

Total number of people [tex]=750[/tex]

Number of people in the [tex]41 - 50[/tex] age group [tex]=268[/tex]

Number of people in the [tex]41 - 50[/tex] age group and favored the Do-It-Yourself books [tex]=69[/tex]

So,

Percentage of favored the Do-It-Yourself books in the [tex]41 - 50[/tex] age group [tex]=\frac{Do-It-yourself\ 41-50\ age}{Total\ Number\ people} *100[/tex]

[tex]=\frac{69}{750} *100[/tex]

[tex]=9.2\%[/tex]

So,  the percentage of people is  [tex]9.2\%[/tex] .

Hence, we can say that the percentage of people in the [tex]41 - 50[/tex] age group and favored the Do-It-Yourself books will be [tex]9.2\%[/tex] .
