2. Is the triangle below a right triangle? Justify your answer.
39
31
35

Answer:

- & ×

Step-by-step explanation:

If we were to put 12 - (-15), the two - would convert to a single +. Thus, the answer should be 12 + 15 which is 27.

If we were to put 24 × [tex]\frac{3}{4}[/tex], we would have to multiply 24 by 3 and divide the answer by 4, which is 18.

Answer:

It is the 3rd option

Step-by-step explanation:

Answer:

x = 4, 10a

Step-by-step explanation:

3(x-2) + 2(2x+5) = 32

3x - 6 + 4x + 10 = 32

3x + 4x + 10 - 6 = 32

7x + 4 = 32

7x = 32 - 4

7x = 28

Divide both side by 7

x = 4

a + 2a + 7a

They are common because the have the same variables.

'a' is with a coefficient of 1

You add the coefficient and attach the variable to it

Therefore,

a + 2a + 7a = 10a

Answer:

The answer is below

Step-by-step explanation:

From the image, we can see that DC is parallel to AB.

Step 1:

Alternate interior angles are angles formed at the inner corners of intersection on opposite sides of transversal when two parallel lines are intersected by a transversal.

Since Line AB is parallel to line DC and cut by transversal DB. So angles CDB and ABD are alternate interior angles and must be congruent.

Step 2:

DB ≅ BD (reflexive property of congruence)

Step 3:

∠A = ∠C = 90° (right angles, given). But to prove that both triangles are congruent, the correct step 3 is:

Since, ∠A = ∠C = 90° and angles CDB and ABD are congruent. This means that the third angles in the both triangles are also congruent. Hence, angle ADB and CBD are must be congruent.

Step 4:

BD = DB, angles CDB and ABD  are congruent, angle ADB and CBD are congruent.

Therefore,  By the Angle-Side-Angle Triangle Congruence Theorem, triangle BCD is congruent to triangle DAB .

Answer:

The answer is the second one .

Answer:

20 m

Step-by-step explanation:

Given :

Leveling cost per square meter = 15

Total leveling cost = 6000

Number of square park leveled :

Tottal cost / unit cost

6000 / 15

= 400 m²

The length of one side of the square

Area of square = s²

where, s = side length

400 = s²

Sqrt(400) = s

s = 20 m

Length of one side = 20 m

c. 7/27

Step-by-step explanation:

add 5 +10 + 7 + 2 + 2 + 1 = 27

3 + 4 = 7

7/27

Answer:

7.5

Step-by-step explanation:

the term similar triangles means they have the same angles and the same scale factor so if we look at rs and jl you see they are 12 and 6. thats is a scale factor of .5 so you take 15 and multiply it by .5 or you can divide it by 2.

The minimum number of moves required for a given number of disks.

We have given that,

The sequences are number of moves 1, 3, 7, 15, 31, 63,

2,2, 4, 8, 16, 32, 64,

Compare the two sequences.

Each term in the sequence of moves is 1 less than the corresponding term in the sequence of differences.

A sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members. The number of elements is called the length of the sequence.

You can find any term in the sequence of moves using the formula

Answer: The side of the house will the ladder reached by ladder = 16.52 feet

Step-by-step explanation:

House is standing vertical on the ground.

By placing ladder, it will become a right triangle with hypotenuse as ladder.

By Pythagoras theorem,

[tex](hypotenuse)^2=(perpendicular)^2+(base)^2[/tex]

i.e.

[tex](17)^2=(Height \ of\ wall\ reached\ by\ ladder)^2+4^2\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=289-16\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=273\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)=\sqrt{273}\approx16.52[/tex]

Hence, the side of the house will the ladder reached by ladder = 16.52 feet (approx)

=========================================

The diagram shows:

Recall that the area of a parallelogram is equal to the base times height

area = base*height

We're told that the area is 117 square units, so that means 13x = 117.

Divide both sides by 13 to isolate x

13x = 117

13x/13 = 117/13

x = 9

The height of the parallelogram is 9

Note how:

area = base*height = 13*x = 13*9 = 117

which helps confirm we have the correct height value for x.

Answer:

[tex]g = \frac{ x - 2}{3} [/tex]

Answer: g=x-2/3

Step-by-step explanation:

When it says make g the subject it means make it on it's own in front of the '=' sign.

To make g the subject, you have to do the inverse to 'undo' the equation.

So, instead of adding 2, you have to take away 2 from x. This would now look like this:

x-2=3g

In algebra, when a number is next to a letter it means times. So instead of multiplying g by 3, you would have to divide x-2 by 3. This would now look like this:

x-2/3=g

Answer:

Step-by-step explanation:

erasers=e  

pencils=p

3e+5p=7.55   ...(1)

6e+12p=17.40

divide by 2

3e+6p=8.70  ...(2)

(2)-(1) gives

p=8.70-7.55=1.15

from (1)

3e+5(1.15)=7.55

3e+5.75=7.55

3e=7.55-5.75

3e=1.80

e=1.80/3=0.60

cost of 1 eraser=$0.60

cost of 1 pencil =$1.15

five plus two equals 7

Answer:

5 & 2

Step-by-step explanation:

X + y = 7

X × y = 10

Solve with the help of trial & error method.

Factors of 10 - 1, 5, 2, 10

Let's take 5 as X & 2 as y.

X + y = 7 --- 5 + 2 = 7

X × y = 10 --- 5 × 2 = 10

Hence, the two numbers that multiply to 10 and add to 7 are 5 & 2
