HAVE A GOOD DAY!

Answer:

A

Step-by-step explanation:

sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]

Rationalise the denominator by multiplying numerator/ denominator by [tex]\sqrt{34}[/tex]

sin x = [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{\sqrt{34} }{\sqrt{34} }[/tex] = [tex]\frac{3\sqrt{34} }{34}[/tex] → A

The experimental probability is [tex]\frac{10}{15+10+40+20+40}=8\%,[/tex] while the theoretical probability, assuming random selection, is [tex]\frac{1}{5}=20\%,[/tex] so the theoretical probability is greater than the experimental probability.

Answer:

-24

Step-by-step explanation:

First find f(3), which is the value of the blue line when x =3

f(3) = -2

Then find g(-1) which is the value of the red line when x= -1

g(-1) = 6

-6 f(3) - 6*g(-1)

-6*-2 - 6(6)

12 - 36

-24

Answer:

Amy will need to read 1 page each day.

Step-by-step explanation:

Total number of page of the magazine = 137 pages

Read pages of the magazine = 42 pages

Remaining pages to be read = 137 pages - 42 pages  = 95 pages

She spends 10 days reading the same number of pages each day until she finishes.

The number of pages read in each of the 10 days = 95 pages / 10 days

                                                           = 9.5 pages

In 10 days Amy reads 9.5 pages

In a day she reads ?

10 days -----------> 9.5 pages

1 day ----------------> ?

= 0.95 page

approximately 1 page per day

Thus, Amy will need to read 1 page each day.

Answer:

I do not think you can simplify it any further

Step-by-step explanation:

If you mean 15p squared - 7 q squared

Because they have different variables; p and q cannot be combined unless it is multiplication or division.

Answer:

1 answer. (possibly 2)

Step-by-step explanation:

There's [tex]\frac{1}{4}[/tex] chance they get the correct answer for a question.

That means if they answer 4 questions, they can expect 1 answer to be correct. If they answer 6 questions, they can expect 1.5 answers to be correct but you can't have 0.5 of an answer so they can expect 1 question answered correctly.

Answer:

No solution.

Answer:

Step-by-step explanation:

An isosceles triangle has two equal sides and two equal base angles.

Given that : AK = KC and MN∥ AC

ΔMNB is similar to ΔACB (congruence property)

ΔANB = ΔANC (SAS congruence property)

ΔCMB = ΔCMA (SAS congruence property)

[tex]\frac{AB}{BN}[/tex] = [tex]\frac{AC}{CN}[/tex] (Angle bisector theorem)

So that:

<BAC = <ACB (base angle property of an isosceles triangle)

/AB/ = /BC/ (side property of an isosceles triangle)

Therefore, ΔABC is an isosceles triangle.

Good Luck

60 degrees, because it's an equilateral triangle, as you can tell because the sides are all the same length.

Answer:

1920 rings

Step-by-step explanation:

We need to simply find the volume of the package and the volume of the cube and then divide the volume of the package by the volume of the cube.

The package is a rectangular prism. The volume of a rectangular prism is:

V = L * W * H

where L = length

W = width

H = height

The volume of the package is:

16 * 10 * 12 = 1920 [tex]in^3[/tex]

The volume of a cube is:

V = L^3

where L = length of side

The volume of the cube is:

V= 1^3 = 1 [tex]in^3[/tex]

The number of rings the jewelry store received is:

1920 / 1 = 1920 rings

Answer:

2 kg.

Step-by-step explanation:

F = m * a   (Newton's Second Law of Motion).

10 = m * 5

The mass m = 10/5 = 2 kg.

Solution,

Here,

Given,

Force= 10N

Acceleration= 5m/s^2

Mass= ?

Therefore, as we know that

Force= Mass× Acceleration

10=M×5

10/5= M

Therefore, M= 5kg.

Answer:

Option (1). (6, 0)

Step-by-step explanation:

The given question is incomplete; here is the complete question.

Which is the ordered pair for the point on the x-axis that is on the line parallel to the given line and through the given point (–6, 10)?

(6, 0)

(0, 6)

(−5, 0)

(0, −5)

Line in orange color is passing through two points (-8, 6) and (4, -4)

Slope of this line = [tex]\frac{\triangle y}{\triangle x}[/tex]

                            = [tex]\frac{6+4}{-8-4}[/tex]

                            = [tex]-\frac{10}{12}[/tex]

                            = [tex]-\frac{5}{6}[/tex]

Other line parallel to this line will have the same slope 'm' = [tex]-\frac{5}{6}[/tex]

Parallel line passes through a point (-6, 10).

Let the other point through which the parallel line passes is (a, b)

Now, [tex]-\frac{5}{6}[/tex] = [tex]\frac{10-b}{-6-a}[/tex]

-5(-a - 6) = 6(10 - b)

5a + 30 = 60 - 6b

5a = -6b + 60 - 30

5a = -6b + 30

a = [tex]-\frac{6}{5}b+6[/tex]

By satisfying with all the options we find only (6, 0) satisfy this equation.

6 = [tex]-\frac{6}{5}(0)+6[/tex]

6 = 6

Therefore, (6, 0) is the other point lying on the parallel line.

Option (1) will be the answer.

Answer: 20

Step-by-step explanation:

Answer:

Step-by-step explanation:

area of triangle = 1/2 * base * height = 1/2 * 9 = 9/2

area  of semicircle = 22/7 * {3 root 2 / 2}^2 = 22/7 *18 / 4 = 22/7 *9/2 = 198/14=99/7

area of figure =  99/7 + 9 /2 =18.6mm2

mark me as the brainliest

Answer:

area of figure= area of semi circle + area of triangle

area of semi circle= 1/2πr²

1/2×3.14×2.12×2.12

1/2×14.11

= 7.06

area of triangle = 1/2×base×height

but I am going to use the Pythagoras theorem to find the its height

= hypotenus² = base²+height²

3²=2.12²+h²

9=4.5+h²

9-4.5=h²

√4.5=√h²

h= 2.12

so area of triangle= 1/2×4.24×2.12

=4.5

area of figure = 70.6+4.5

= 75.1mm²

hope it helps even if its not correct just wanted to try

Good luck on your assignment

Answer:

The surface area of the cylinder is 276.32m²

Step-by-step explanation:

To solve this problem we have to calculate the circle area and the lateral area

To calculate the area of ​​the circle we use the following formula

a = area

r = radius = 2m

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (2m)²

a = 3.14 * 4m²

a = 12.56m²

The area of the circle is 12.56m²

To calculate the lateral area of ​​the cylinder we use the following formula

a = area  =

h = heighti = 20m

r = radius = 2m

π = 3.14

a = 2 * π * r * h

we replace with the known values

a = 2 * 3.14 * 2m * 20m

a = 6.28 * 40m²

a = 251.2m²

The lateral area of ​​the cylinder is 251.2m²

Now we add the lateral area of ​​the cylinder with 2 times the area of ​​the circle and obtain the area of ​​the cylinder

251.2m²  + (2 * 12.56m²) = 276.32m²

The surface area of the cylinder is 276.32m²

Answer:

346 cm²

Step-by-step explanation:

Area of square:

Area = [tex]Length*Length[/tex]

A = 20*20

A = 400 cm²

Area of rectangle:

Length = 3 cm

Width = 20-2 = 18 cm

Now, The Area:

Area = [tex]Length * Width[/tex]

Area = 3 * 18

Area = 54 cm²

Now, The difference in their areas:

=> 400-54

=> 346 cm²

The correct amount is $18

Step-by-step explanation:

The change in her checking account here refers to a reduction in balance due to a deduction made for a gym membership of $18  per year.

Integer, as we know, is a whole number,  not a fraction.

In all fairness, the integer will indicate the change in her checking account due to her gym  membership payment is $18, the first option out of the multiple choices provided
