what is the product –8(7 – 3 .2)

Answer:

The value of x is equal to 30.

Step-by-step explanation:

Let's define what are 2 equations are:

Since we are dealing with a straight line, the line's angle will always equal 180°.

Since the 2 angles must add up to 180°, then they must be supplementary angles.

We can set up our equation to solve for x:

This equation states that the 2 angles, given in formulas, must be equal to the angle of the line.

We can now solve this equation and get a value of x:

∴ we have found the value of x to be equal to 30.

Answer:

measure of angle C = 18°

c = 2.47

a = 7.61

Step-by-step explanation:

Make sure your calculator is in degree mode.

Angle A measures 72°, so angle C measures 18° (Angles A and C are complementary angles, so their sum is 90°).

[tex] \sin(18) = \frac{c}{8} [/tex]

[tex]c = 8 \sin(18) = 2.47[/tex]

[tex]a = 8 \cos(18) = 7.61[/tex]

Answer: 12

Step-by-step explanation:

Because a translation is a rigid motion, we know that YZ corresponds to GH (and they will have the same length).

Now, we can the fact that EFGH is a rectangle to obtain that EF=GH=12 (since opposite sides of a rectangle are congruent)

Hence, YZ=12.

Answer:

80m

Step-by-step explanation:

Pythageoreum Theorum since it is a right triangle.

a^2 + b^2 = c^2

60^2 + b^2 = 100^2

3600 + b^2 = 10,000

-3600              -3,600

b^2 = 6,400

Square root both sides of the equation

b = [tex]\sqrt{6400}[/tex]

[tex]\sqrt{6400}[/tex] = 80

The length of side a is 80 m

Answer:

a1=2 and r=-1

Step-by-step explanation:

"A geometric series is a series with a constant ratio between successive terms".

Here, we can observe that the first term 'a' is '2'.

And the common ratio 'r' =

Therefore, the first term 'a' is 2 and common ratio 'r' is '-1'.

First term, a, is 2.  Next term, -2, is the product of 2 and -1 and is -2.  Next term, 2, is the product of -2 and -1.  Thus, the first term, a, is 2 and the common ratio, r, is -1

Answer:

a1 = 2 and r = –1

Step-by-step explanation:

The answer above is correct.

Answer:

1/32

Step-by-step explanation:

We can break this question down. If we had 1 person and they are right-handed, the probability is 1/2 because they are either left-handed or right-handed. Knowing that, we can multiply the probability of having 1 person being right-handed 5 times because there are 5 people in the question.

1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/(2⁵) = 1/32

Therefore, the probability of randomly selecting 5 people who are right-handed is 1/32.

Answer:

80 degrees

Step-by-step explanation:

The three angles of the triangle must sum to 180 degrees

70 + 30 + x = 180

x = 180 -70-30 = 80

The trinomial, 3x² + 13x – 10, when factored will give you: (3x + 10)(x - 1).

To factor a trinomial, we need to find two factors that would give us the exact trinomial when expanded.

Given, 3x² + 13x – 10:

3x² -3x + 10x - 10

(3x² - 3x) + (10x - 10 )

3x(x - 1) +10(x - 1)

(3x + 10)(x - 1)

Answer:

One

Step-by-step explanation:

For unique triangles with 3 sides, the sum of the two shorter sides must be greater than the third side.

Shorter sides:  6 cm and 2.5 cm

Longer side:  6.5 cm

6 + 2.5 = 8.5

As 8.5 > 6.5 this is a unique triangle

As the side lengths are fixed, only one unique triangle can be formed.

Answer:

16

Step-by-step explanation:

x^2 -8x=0

rewrite in this form and add 16 to both sides:

x² + 2(- 4)x + 16 = 0 + 16

(x - 4)² = 16 ( take square root of both sides )

x - 4 = ±  4

x =  4 ± 4

x=8 , x= 0

step 1

Find the average growth per year of the populations of rabbits farm A

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=40

average=[40-5]/2---------> 17.5

step 2

Find the average growth per year of the populations of rabbits farm B

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=30

average=[30-5]/2---------> 12.5

step 3

Compare the average growth per year of the populations of rabbits on both farms

farm A=17.5

farm B=12.5

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.

therefore

the answer is the option C)

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.

Answer:

84 inches

Step-by-step explanation:

It is the perimeter.

Koda needs 84 inches of ribbon to put it around the edge of the board.

A classroom board is 24 inches wide and 18 inches tall, Koda s putting ribbon along the outside edge of the board.

Perimeter is the measure of the figure on its circumference.

Here,
length = 24 inch
width = 18 inch
The perimeter of the board, = 2 {length  + width]
                                             = 2 [24 + 18]

                                             = 84

Thus, Koda needs 84 inches of ribbon to put it around the edge of the board.
