Answer

1)90°. 2)51°. 3)39°.

Step-by-step explanation:

1) it is straight so it is 90°

2)51° because the kite is symmetrical so it should be the same as the other side

3)90+51=141

180-141=39° so it is 39°

Answer:

Last option

Step-by-step explanation:

That is your best choice because that is the option that tells you the angles are congruent and not the sides. I could be wrong tho.

The hypothesis to proof that the base angles of the isosceles triangle are congruent will be AC≅AB

An isosceles triangle is a triangle that has at least 2 congruent sides. The congruent sides are the legs of the triangle while the remaining side is called the base. The angles on the base is called the base angles.

The base angles of an isosceles triangle are congruent. The base angles are

∠BCA and ∠CBA and they are congruent. The sides AC and AB are congruent. AC≅AB.

Therefore, the hypothesis to proof that the base angles of the isosceles triangle are congruent will be as follows:

Answer:

No invariant point

Step-by-step explanation:

Yo!

When we translate a form, in this case a polygon We must observe the direction of the vector. Since our vector is:

1) Let's apply  that translation to this polygon, a square. Check it below:

2) The invariant points are the points that didn't change after the transformation, simply put the points that haven't changed.

Examining the graph, we can see that no, there is not an  invariant point, after the translation. There is no common point that belongs to OABC and O'A'B'C' simultaneously. All points moved.

To find the answer, calculate the area of the rectangles.

Area of rectangle = Length * Width

Rectangle A                                   Rectangle B                         Rectangle C

= 6 * 3                                              = 9 * 9                                  = 5 * 4

= 18 cm²                                           = 81 cm²                              = 20cm²

Rectangle D                                  Rectangle E

= 9 * 2                                              = 7 * 2

Answer:

67 ≤ x ≤ 73

Step-by-step explanation:

The absolute value of a real number x is the non negative value of x. Therefore the absolute value of x (|x|) = x for x ≥ 0 and -x for x < 0.

An expression |x - a| = b signifies that x - a = b or -(x - a) = b

Given that |x − 70| ≤ 3, hence:

|x − 70| ≤ 3

x - 70 ≤ 3 or -(x - 70) ≤ 3

x ≤ 3 + 70 or x - 70 ≥ -3

x ≤ 73 or x ≥ -3 + 70

x ≤ 73 or x ≥ 67

67 ≤ x ≤ 73

Hence the solution of |x − 70| ≤ 3 is 67 ≤ x ≤ 73

Answer:

1/3 for a.

2/3 for b.

Answer:

rs 200

Step-by-step explanation:

Let cost price = x

At 30% profit; marked price of radio is 30% of x = (100% + 30%) = 130%x

Discount = rs 3%

Profit made = 30

Hence,

Marked price - discount = cost price + 30

130%x - 30 = x + 30

1.3x - 30 = x + 30

1.3x - x = 30 + 30

0.3x = 60

Divide both sides by 0.3

0.3x / 0.3 = 60/ 0.3

x =

1.3x / 1.3 = 60 / 1.3

x = 200

Hence, cost price = rs 200

Answer:9

Step-by-step explanation:each friend get 5 because if he has 47 keeps 2 and has 5 friend 45 divided 5 equals 9

Each friends receive 9 marbles.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.

Given that the Julio has 47 marbles. And he keeps his two favorite marbles.

To share the marbles, she has;

= 47-2

= 45

Then she equally shares the remaining with five friends.

Marbles for each friends = remaining marbles / number of friends.

Marbles for each friends = 45 / 5.

Marbles for each friends = 9

Therefore, each friend receive 9 marbles.

Answer:

The graph is the equation 3x + 4y = 12 is attached below.

Step-by-step explanation:

Given the equation

3x + 4y = 12

First,

We need to determine the y-intercept:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

substitute x = 0 in the equation 3x + 4y = 12

3x + 4y = 12

3(0) + 4y = 12

0 + 4y = 12

4y = 12

divide both sides by 4

4y/4 = 12/4

y = 3

Thus, the y-intercept is: (0, 3)

Now, check the attached graph below.

Determining the y-intercept of the equation from the graph

From the graph, it is clear

at x = 0, y = 3

Thus, the y-intercept is (0, 3)

Determining the x-intercept of the equation from the graph

From the graph, it is clear

at y = 0,

3x + 4(0) = 12

3x = 12

x = 4

Thus, the x-intercept is (4, 0)

The graph is the equation 3x + 4y = 12 is attached below.

Answer:

4) b^10

5) 15x^11y^6

6) 8y^5x + 3x

Step-by-step explanation:

b^6 + b^4 = b^10 because this is multiplication. So you have to add the degrees

(3x^3y^5)(5x^8y^1) = 15x^11y^6. This is because

3 *5 = 15.

x^3 +x^8 = x^11

y^5 + y^1 = y^6.  

You have to add the degrees since this is also multiplication.

(2y^2)(4xy^3) + 3x = 24y^5x^2. This is because

2 * 4 = 8

y^2 + y^3 = y^5

x + 0 = x

Therfore, it is (8y^5x) + 3x as the final answer.

Answer:

191 grams

Step-by-step explanation:

12.4×5.6×2.5=173.6

7.9×173.6=1371.44

9.0×173.6=1562.4

1562.4-1371.44=191

Answer:

1) ∠A=84°

2) ∠C=20°

Step-by-step explanation:

1)

First, find ∠C:

(I'm assuming the exterior angle of 126° makes a straight line with ∠C)

The angles on a straight line always add up to 180. Therefore:

∠C+126=180

∠C=180-126

∠C=54

Then find ∠B:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+∠B+54=180

∠A+∠B=126

(we know ∠A=2(∠B))

2(∠B)+∠B=126

3(∠B)=126

∠B=42

Now, find ∠A:

∠A=2(∠B)

∠A=2(42)

∠A=84°

2)

First, find ∠B:

(Again, I'm assuming the exterior angle of 100° makes a straight line with ∠B)

The angles on a straight line always add up to 180. Therefore:

∠B+100=180

∠B=180-100

∠B=80

Then find ∠A:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+80+∠C=180

∠A+∠C=100

(we know ∠A=4(∠C))

4(∠C)+∠C=100

5(∠C)=100

∠C=20°
