Calculate the area of triangles using two different methods. figures are now drawn to scale.

Answers

Answer 1

Answer:

the formula is base times hight divided by two so use the formula to sovle the problem

Step-by-step explanation:

Answer 2

The area of the triangles given are 52.5 feet² and 369 inches² respectively.

What is Area?

Area of a two dimensional shape is the total region which is bounded by the object's shape.

The basic formula to calculate the area of a triangle is,

Area = [tex]\frac{1}{2}[/tex] × base × height

1. Base = 12 + 3 = 15 feet

Altitude/height = 7 feet

Area = [tex]\frac{1}{2}[/tex] × 15 × 7 = 52.5 feet²

2. Calculating the area of two separate triangles and then adding it,

Area = ([tex]\frac{1}{2}[/tex] × 32 × 18) + ([tex]\frac{1}{2}[/tex] × 9 × 18)

= 288 + 81

= 369 inches²

Hence the area of the two figures is 52.5 feet² and 369 inches² respectively.

factorise p-q-x(q-p)

Answers

Answer:

(1 + x)(p - q)

Step-by-step explanation:

Given

p - q - x(q - p) ← distribute parenthesis by - x

= p - q - qx + px ← rearrange terms in p and terms in q

= p + px - q - qx ( factor first/second terms and third/fourth terms )

= p(1 + x) - q(1 + x) ← factor out (1 + x) from each term

= (1 + x)(p - q)

A trampoline park costs $12 for the first hour and $6 for each additional hour. Flynn pays $30 at the trampoline park. Select the equation that represents the given situation and find the number of additional hours Flynn stays at the trampoline park after the first hour.
A. 12x + 6 = 30; 3 hours
B. 6x + 12 = 30; 3 hours
C. 6x + 12 = 30; 2 hours
D. 12x + 6 = 30; 2 hours

Answers

Answer is B. 12 dollers for 'admission' and then you have 6 per hour of time

The equation that represents the given situation is 12 + 6x = 30.

The number of additional hours is 3.

Option B is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

A trampoline park costs $12 for the first hour and $6 for each additional hour.

Amount paid at the park = $30

Now,

12 + 6x = 30

x is the number of hours.

Solve for x.

12 + 6x = 30

6x = 30 - 12

6x = 18

x = 3

Thus,

The equation is 12 + 6x = 30.

The number of hours is 3.

What is the two fifths of the collection pilers, hammers, wrenches, saws.

Answers

Answer:

Pliers

Step-by-step explanation:

From the picture attached,

Number of pliers = 4

Number of hammers = 2

Number of wrenches = 2

Number of saws = 2

Total collection of tools = 4 + 2 + 2 + 2 = 10

Since, two fifth means,

[tex]\frac{2}{5}=\frac{2\times 2}{5\times 2}[/tex]

[tex]\frac{2}{5}=\frac{4}{10}[/tex]

That means tool with 4 counts out of total 10 tools will be the answer.

Will a pair of 6 feet 11 inch long skis fit in a wardrobe that is 3 feet long, 2 feet wide and 6 feet high?

Answers

Answer:

Step-by-step explanation:

Length of a pair of skis = 6 feet 11 inches

Maximum length of a the skis that can be fitted in a wardrobe is along the diagonal of the wardrobe.

From the picture attached,

BC² = 3² + 2² [By Pythagoras theorem]

BC = √(13)

By applying Pythagoras theorem in ΔABC,

AB² = AC² + BC²

AB² = 6² + (√13)²

= 36 + 13

AB = √49

Ab = 7 feet

Since, "diagonal length of the wardrobe is more than the length of skis,

skis can be fitted"

use Pythagorean theorem

to simplify down to find the opposite angle

b= rad 7

The sum of the squared lengths of the other two sides of a right triangle equals the square of the hypotenuse's length, which can be defined as follows:

Finding the sin θ value:

[tex]\to \cos \theta =-\frac{3}{4}[/tex]

[tex]\to \sin \theta =?[/tex]

[tex]\sin \theta = \frac{opposite}{hypotenuse}\\\\\cos \theta =\frac{hypotenuse}{adjacent}\\\\[/tex]

therefore

hypotenuse= -3

adjacent= 4

Using the Pythagorean theorem to find the opposite:

Hypotenuse²= Adjacent²+ Opposite²

[tex]-3^2= 4^2+x^2\\\\9=16+x^2\\\\x^2= -16+9\\\\x^2=-7\\\\x= -\sqrt{7}\\\\[/tex]

Which function represents this sequence?

A.
f(n) = 4 ∙ 2n-1

B.
f(n) = 4n-1

C.
f(n) = 2 ∙ 4n-1

D.
f(n) = 2n-1

Answers

Answer: A. f(n) = 4 ∙ 2n-1

Step-by-step explanation:

because the 1st term is 4 according to your image, and then you will have to multiply that by its common difference and using your table, to get from 4 to 8 then 8 to 16 you would multiply by 2, and you would finally multiply that by n or known as the number of terms and 1 making the equation. f(n) = 4 ∙ 2n-1 I hope this is very helpful for everyone.

Your task is to group the arrays a[i] by their mean values, so that arrays with equal mean values are in the same group, and arrays with different mean values are in different groups. Each group should contain a set of indices (i, j, etc), such that the corresponding arrays (a[i], a[j], etc) all have the same mean. Return the set of groups as an array of arrays, where the indices within each group are sorted in ascending order, and the groups are sorted in ascending order of their minimum element.ExampleFora = [[3, 3, 4, 2], [4, 4], [4, 0, 3, 3], [2, 3], [3, 3, 3]]the output should bemeanGroups(a) = [[0, 4], [1], [2, 3]]mean(a[0]) = (3 + 3 + 4 + 2) / 4 = 3;mean(a[1]) = (4 + 4) / 2 = 4;mean(a[2]) = (4 + 0 + 3 + 3) / 4 = 2.5;mean(a[3]) = (2 + 3) / 2 = 2.5;mean(a[4]) = (3 + 3 + 3) / 3 = 3.There are three groups of means: those with mean 2.5, 3, and 4. And they form the following groups:Arrays with indices 0and 4 form a group with mean 3;Array with index 1 forms a group with mean 4;Arrays with indices 2and 3 form a group with mean 2.5.Note that neithermeanGroups(a) = [[0, 4], [2, 3], [1]]normeanGroups(a) = [[0, 4], [1], [3, 2]]will be considered as a correct answer:In the first case, the minimal element in the array at index 2 is 1, and it is less then the minimal element in the array at index 1, which is 2.In the second case, the array at index 2 is not sorted in ascending order.Fora = [[-5, 2, 3], [0, 0], [0], [-100, 100]]the output should bemeanGroups(a) = [[0, 1, 2, 3]]The mean values of all of the arrays are 0, so all of them are in the same group.Input/Output I WILL GIVE BRAINLIEST!!!
