If three coins are thrown what is the probcbility Obtaining at least two head?​

Answer:

128 in.

Step-by-step explanation:

1 ft = 12 in

10 x 12 = 120

120 + 8 = 128

128 in.

Two or more angles whose sum is 180° are called supplementary angles. The measure of the ∠y is 120°.

Two or more angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Given the puck strikes the wall at an angle of 30°, it goes away at the same angle of 30°. Therefore, the measure of angle y can be found using the sum of the angle as a supplementary angle. Thus, we can write,

30° + ∠y + 30° = 180°

60° + ∠y = 180°

∠y = 180° - 60° = 120°

Hence, the measure of the ∠y is 120°.

The additional point could be added to the graph to show Amber that the equation does not represent a function will be (8, -4). Then the correct option is C.

A statement, principle, or policy that creates the link between two variables is known as a function.

The equation is given below.

x = (1/2)y²

For the single value of x, the value of y is not single.

Thus, it is not a function.

Answer: 15x+30

Step-by-step explanation:

The value of 5(3x+6) is 15x+30

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Given that;

[tex]5(3x+6)[/tex]

 /        \

[tex]15x+30[/tex]

Therefore, The value of 5(3x+6) is 15x+30

Question 3: 1/15   Question 4: 50

Step-by-step explanation:

Hey ! there

Answer:

Step-by-step explanation:

In this question we are provided with an equation that is 5 ( 3x - 1 ) = 55 and we are asked to find the value of 2x - 2 .

Firstly , we need to find the value of x . So we need to solve the equation .

SOLUTION : -

[tex] \quad \longmapsto \qquad \: 5(3x - 1) = 55[/tex]

Step 1 : Dividing with 5 on both sides :

[tex] \quad \longmapsto \qquad \: \dfrac{ \cancel{5}(3x - 1)}{ \cancel{5}} = \cancel{\dfrac{55}{5} }[/tex]

On cancelling , We get :

[tex] \quad \longmapsto \qquad \:3x - 1 = 11[/tex]

Step 2 : Adding 1 on both sides :

[tex] \quad \longmapsto \qquad \:3x - \cancel{1} + \cancel{1} = 11 + 1[/tex]

On simplifying , We get :

[tex] \quad \longmapsto \qquad \:3x = 12[/tex]

Step 3 : Dividing with 3 on both sides :

[tex] \quad \longmapsto \qquad \: \dfrac{ \cancel{3}x}{ \cancel{3}} = \cancel{ \dfrac{12}{3} }[/tex]

We get ,

[tex] \quad \longmapsto \qquad \: \underline{\boxed{\frak{x = 4}}}[/tex]

→ Therefore , value of x is 4 .

Verifying : -

Now we are verifying whether our answer is wrong or right . So ,

Therefore , our value of x is correct/valid .

We need to find the value of 2x - 2 .

[tex] \quad \longmapsto \qquad \:2x - 2[/tex]

So substituting value of x in it :

[tex]\quad \longmapsto \qquad \:2( \bold{4}) - 2[/tex]

Multiplying 2 with 4 :

[tex]\quad \longmapsto \qquad \:8 - 2[/tex]

Subtracting 2 from 8 :

[tex]\quad \longmapsto \qquad \: \blue{\underline{\boxed{\frak{6}}}} \quad \: \bigstar[/tex]

Answer:

Enough to cover the seat

Step-by-step explanation: If this is a question dealing with the area of said object (seat) simply make an equation to find the area of your object.  So let's say we got a seat that is 4 feet wide and 6 feet tall.

We will multiply 4 feet times 6 feet and that's where we get 24 feet.

So we know how many inches are in a feet right, there are 12 inches per foot. So 12 time 24 is our problem 12 x 24 = 288 inches. So we would need enough stain to cover 288 inches .

Answer:

we know that

Victoria has $125 to spend

[purchase price skateboard]=$139.99-0.15*$139.99-----> $139.99-$21

[purchase price skateboard]=$118.99

sales tax is 7%----------> 0.07*$118.99----------> $8.33

sales tax is $8.33

Victoria has to pay [$118.99]+[$8.33]=$127.32

$127.32 > $125

therefore

Victoria has not enough money to buy the skateboard

the answer is

Answer:

Step-by-step explanation:

Understanding the situation

Parallel lines have the same slopes.

If line t is parallel to line u then the slope of line t is the same as the slope of line u.

Finding the slope of line t

Slope formula = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

where the x and y values are derived from points on the line

here, we are given that line to goes through (2,2) and (10,9)

Given that we can assign variables

we have (x1,y1) = (2,2) so x1 = 2 and y1 = 2

we also have (x2,y2) = (10,9) so x2 = 10 and y2 = 9

Now that we have assigned variables we plug them into the formula

Recall formula : [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

==> plug in x1 = 2 , y1 = 2, x2 = 10 and y2 = 9

[tex]slope =\frac{9-2}{10-2}[/tex]

==> simplify top and bottom

[tex]slope =\frac{7}{8}[/tex]

The slope of line t is 7/8

Finding the slope of line u

Because line t and line u are parallel line u also has a slope of 7/8

If the two prisms are stacked on top of each other then the height of the prism is 30 inches. Then the volume of the prism will be 1080 in³.

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.

A toy store is building a display with two rectangular prisms.

The base of each prism is a square with an edge length of 6 inches.

One prism is 10 inches tall and the other is twice as tall.

The two prisms are stacked on top of each other.

Then the total volume of the display will be

The volume of the prism will be

Volume = Base area × Height

Then the height of the second prism will be

h₂ = 2 × 10 = 20 inches

Then the volume of the prism will be

Volume = 6 × 6 × 10 + 6 × 6 × 20

Volume = 360 + 720

Volume = 1080 cubic inches

Answer: 7cm

Step-by-step explanation:

Use pythagorean theorum:

Variables:

Let the edge = A

Face diagonal (F) = 10cm

Inner diagonal (I) = sqrt(150) cm

A^2 = I^2 - F^2

A^2 = [sqrt(150)]^2 - 10^2

A^2 = 150 - 100

A^2 = 50

A = sqrt(50)

A = 7.0710678 cm

A = 7cm (to the nearest tenth)

so, length of an edge = 7cm

Step-by-step explanation:

area of the square :

6×6 = 36 cm²

area of the triangle :

6×4/2 = 6×2 = 12 cm²

height of triangle :

area of the triangle is

10×height/2 = 40

10×height = 80

height = 80/10 = 8 cm

width of the logo :

the central square has ashtray an area of 5×5 = 25 cm².

that leaves us 125 - 25 = 100 cm² for the 4 triangles.

I assume all 4 triangles are equal, so each has an area of 100/4 = 25 cm².

the area of such a triangle is

baseline × height / 2.

so, in our case

5 × height / 2 = 25

5 × height = 50

height = 10 cm

and so, the width of the logo is 2 times the height of these side triangles, and 1 time the side length of the central square :

2×10 + 5 = 25 cm

Answer:

So we must determine the distance between our two given points and that can be found using the distance formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].

Plugging the values into the equation and solve

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d=\sqrt{(-9-5)^2+(-2-6)^2}[/tex]

[tex]d=\sqrt{(-14)^2+(-8)^2}[/tex]

[tex]d=\sqrt{196+64}[/tex]

[tex]d=\sqrt{260}[/tex]

[tex]d=16.125\ units[/tex]

Therefore, our final answer is that the distance is 16.125 units
