Dilate D(7,4) by a scale factor of k = 3

Answer:

no, it does not format a proportion, they are not equal

The circumference formula is 168.6

where r is the radius given to us as 26.85, and pi is to be 3.14. In our formula then, we have

.

Doing that multiplication and rounding to the nearest tenth leaves us with a circumference of 168.6 inches.

Answer:

b. 31.

Step-by-step explanation:

The other 2 angles in the triangle are congruent so they are:

(180 - 118) / 2

= 31 degrees.

The possible measure of two similar angles in an isosceles triangle could be b. 31 °

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know in an isosceles triangle two sides are equal and angles opposite sides to the equal side are also equal.

We also know that the sum of all the interior angles in a triangle is 180°.

Let, The similar angles be 'x'.

Therefore,

x + x + 118 = 180

2x = 62.

x = 31°.

[tex]tan = \frac{o}{a} [/tex]

Hypotenuse : Opposite the right angle. : 13

Opposite : Opposite the B angle : 5

Adjacent : The only side left : 12

we need opposite and adjacent, hypotenuse is irrelevant in this question.

Substitute the numbers

[tex]tan( \frac{5}{12} )[/tex]

Answer: 140

Step-by-step explanation:

Angle 4 and A are supplementary meaning they add to 180

Thus you can do 180-40 = 140 to get that angle A = 140.

Since the two lines are parallel, Angle A is congruent to Angle D. Then, since Angle D is opposite Angle 3, we know that that Angle 3 and Angle D are congruent.

Answer: 57 x 8.50 = 484.50

Answer:

1 Hour and 20 minutes

Step-by-step explanation:

Time = Distance ÷ Speed

The total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes and this can be determined by using the formula of speed.

Given :

The formula of speed is used to determine the time taken by Andy to cover the total distance. The formula of speed is given by:

[tex]\rm s = \dfrac{D}{t}[/tex]

where 's' is the speed, 'D' is the distance and 't' is the time.

Now, the time taken by Andy to cover the distance of 30 Km with the speed of 24 Km/hr is:

[tex]\rm 24 = \dfrac{30}{t}[/tex]

[tex]t = \dfrac{30}{24}[/tex]

t = 1.25 hrs.

Now, the time taken by Andy to cover the distance of 12 Km with the speed of 8 Km/hr is:

[tex]\rm 8 = \dfrac{12}{t}[/tex]

[tex]t = \dfrac{12}{8}[/tex]

t = 1.5 hours.

So, the total time taken by Andy is (1.25 + 1.5) 2.75 hrs or 165 minutes.

Answer:

Step-by-step explanation:

Answer:

x = 2.5

y = 5

Step-by-step explanation:

2x + 3y = 20

2x + y = 10 then y = 10 - 2x

substitute for y:

2x + 3(10 - 2x) = 20

2x + 30 - 6x = 20

reduce:

-4x = -10

divide both sides by -4:

x = 2.5

y = 10 - 2(2.5) = 5

check:

2(2.5) + 3(5) = 20

20 = 20

and

2(2.5) + 5 = 10

10 = 10

Answer: A 128 square sm

Step-by-step explanation:

So the wedge consists of a square and a triangle. We need to find the area of both using 2 formulas:

A=1/2bh for triangle

A= l*w for square

Starting with the square 8*10=80 so the area of the square is 80 square cm

Now the triangle is 12*8/2 so = 48 square cm

So add the two to get 48+80= 128 Square centimeters which is choice A
