Answer:

2 3/5

Step-by-step explanation:

convert mixed number into improper fraction

(whole number × denominator + numerator over denominator)

4 × 3 + 1

12 + 1

13/3

13/3 × 3/5

multiply numerators

39

multiply denominators

15

39/15

3 can be divided into both number 39 and number 15 so:

13/5

this is simplest form as an improper fraction

if the teacher wants simplest form as a whole number, the answer is:

2 3/5

Answer:

4 1/3 X 3/5 = 2 3/5

Step-by-step explanation:

First I got 13/5 then I had to convert to 2 3/5.

Step-by-step explanation:

x=1.61y

since y is the amount of miles

and

x is in kilometers

Answer with step-by-step explanation:

The graph passes through both (1,4) and (2,0)

Thus it's slope is the difference of ordinates over difference of abscissae or -4

Thus the equation becomes y = -4x + b

This b is the required b

At x=2 ; y=0

Thus 0= -8 + b

b=8

Answer:

r = 2.04%

Step-by-step explanation:

r = n{(A/P)^1/nt - 1}

Where,

r = interest rate = ?

n = number of periods = 12

A = future value = $22,960

P = present value = $20,960

t = time = 4 years

r = n{(A/P)^1/nt - 1}

r = 12{(22,960/20,987)^1/12*4 - 1}

= 12{(1.09)^1/48 - 1}

= 12{(1.09)^0.02 - 1}

= 12 (1.0017 - 1)

= 12(0.0017)

= 0.0204

r = 0.0204 × 100

= 2.04%

r = 2.04%

Answer:

the measure of angle 4 is 52 degrees.

Step-by-step explanation:

The measure of angles 3 and 4 added together is 90 degrees. Angle 3 is 38 degrees. 90-38=54.

Answer:

∠ 4 = 52°

Step-by-step explanation:

The 3 angles lie on a straight line and sum to 180°, that is

90 + ∠ 3 + ∠ 4 = 180, substitute ∠ 3

90° + 38° + ∠ 4 = 180°

128° + ∠ 4 = 180° ( subtract 128° from both sides )

∠ 4 = 52°

Answer:

27*2/3=18

18*2/3=12

Step-by-step explanation:

I would look at the ratio of two terms

and the difference of two terms

to see if there might be a pattern

for example, 27, 18, 12

the difference between 27 and 18 is 9

the difference between 18 and 12 is 6

That is not a constant difference.

Let's try ratios:

27/18 = 1.5

18/12 = 1.5

that looks promising... we get the same ratio

so on the next bounce, expect

18/x = 1.5

maybe it's easier if we flip the ratio 1.5 (3/2) to 2/3 and so

18= 2/3 * 27

12= 2/3* 18 = 2/3 * 2/3 * 27

If we try to make a pattern

first peak = (2/3)^0 * 27

2nd peak = (2/3)^1 *27

3rd peak = (2/3)^2 * 27

Answer:

There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.

A

Step-by-step explanation:

because if you put A into a calculator it equals 81.

hope this helps

Answer:

81 is the perfect square of the first option

Step-by-step explanation:

It is asking for the perfect square so the third option will be eliminated because that is cubed.

The fourth option will also be eliminated because it is multiplication.

The second option will be eliminated because it has addition.

81 is the perfect square of the first option

Answer:

$18

Step-by-step explanation:

we proceed by first solving for the unit cost of a sheet

then calculate the cost for any number of sheet

We are told that a builder could buy 6 sheets for the cost of $9

this means that one sheet would cost 9/6= $1.5

Now the builder buys 12 sheets

therefore the cost of 12 sheets will be

12*1.5= $18

Answer:

[tex]\sqrt{59}[/tex]

Step-by-step explanation:

7^2 is 49 and 8^2 is 64, which means the square root of any number between 49 and 64 (exclusive) will be in between 7 and 8, and it's also going to be irrational, because it's not a perfect square.

One number between 49 and 64 is 59, so [tex]\sqrt{59}[/tex] is an irrational number between 7 and 8

Remember from now on :

E = 10

Let's solve now....

[tex]1.16 \times {10}^{ - 7} = [/tex]

[tex]116 \times {10}^{ - 9} = [/tex]

[tex]0.000000116[/tex]

Answer:

The scale factor is 1/4

Step-by-step explanation:

Here, we are interested in finding the scale factor that helped convert the first point to the second.

Hence, what turned (8,12) to (2,3)

What we shall do here is to simply divide term 2 by term i.e

That would be 2/8 or 3/12 = 1/4

The scale factor was 1/4.

Given that,

The point (8, 12) was dilated to become point (2, 3).

We have to determine,

What was the scale factor?

According to the question,

Scale factors are closely related to the concepts of ratio and proportions.

In ratio and proportions, we multiply or divide a given amount to form a new quantity.

The point (8, 12) was dilated to become point (2, 3).

Therefore,

The scale factor was,

[tex]\rm Scale\ factor = \dfrac{New \ point \ lies \ on \ axis}{Old \ point \ lies \ on \ axis}[/tex]

Substitute the points in the formula for the x-axis,

[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ x-axis}{Old \ point \ lies \ on \ x-axis}\\\\Scale\ factor = \dfrac{2}{8}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]

And substitute the points in the formula for the y-axis,

[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ y-axis}{Old \ point \ lies \ on \ y-axis}\\\\Scale\ factor = \dfrac{3}{12}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]

Hence, The scale factor was 1/4.

So BASically

A triangle has 3 sides

One is the hypotenuese

The other is the Base

and the last one is perpendicular

Step-by-step explanation:directly

opposite the right angle is The HYPOTENUESE

For any triangle, the longest side is always opposite the largest angle. The largest angle of a right triangle is always the 90 degree angle. If you had any larger angle, then the triangle wouldn't be a right triangle and instead it would be obtuse.

In a right triangle, the longest side is given the special name hypotenuse. The other sides of a right triangle are called the legs.

Step-by-step explanation:

Answer:

the area = 28.27 or you can write the answer out as 28.2744 or also 28.27433

Step-by-step explanation:

start with what we know. the formula for solving this is A=pi R squared

so, area= pi (3.1416)

then, multiply that by the radius given, which is 3.

So, 9.4248 × 3 = 28.2744 square inches

or 28.27 sq.in.

Answer:

Option A is the correct answer. ; x=-2/3 and x=3/2

Step-by-step explanation:

We have been given that p(x)=(3x+2)(2x−3) is a polynomial.

According to the question's statement, Question asks us to find the zeros of the polynomial.

Let's head to the question in order to get required answer.

p(x)=(3x+2)(2x−3)

=> p(x) = 3x(2x-3) + 2(2x-3)

=> p(x) = 6x² - 9x + 4x - 6

=> p(x) = 6x² - 5x - 6 (This is the standard form for the given polynomial)

Now, We need to find the zeros of the polynomial. So, In order to find its zeros, we need to put p(x).

p(x) = (3x+2)(2x-3)

=> 0 = (3x+2)(2x-3)

=> (3x+2) = 0 or (2x-3) = 0

=> x= -2/3 or x = 3/2

Hence, If p(x)=(3x+2)(2x−3), x = -2/3 & x= 3/2 are the zeros of the polynomial.
