Answer:

5

Step-by-step explanation:

(12x + 19) + (22x - 9) = 34x + 10

since both are supplementary angles, 34x + 10 = 180

simples algebra leads us to x = 5

Answer:

280cm^3

Step-by-step explanation:

Find the volume of the original container (490), and subtract that from the volume of the second container (770) to get 280cm^3.

The difference in the volume that the two compartments have:

280 [tex]cm^3[/tex]

Given that,

Sum of parallel sides = 15cm + 5cm

= 20 cm

Height = 7 cm

[tex]= 4 cm[/tex]

To find,

The volume of the compartment = Area of base × Height

= {(1/2) × 20} × 7}  × 7

= 490 [tex]cm^2[/tex]   ...(i)

Now,

The new compartment's height = 7 + 4

= 11 cm

Volume for the new compartment = Area of base × Height

= 70 × 11

= 770 [tex]cm^3[/tex]    ...(ii)

Now,

To find the difference in the volumes,

(ii) - (i)

= 770 - 490

= 280 [tex]cm^3[/tex]

Thus, 280 [tex]cm^3[/tex] is the correct answer.

Answer:

10

Step-by-step explanation:

it is because of Pythagoras's theorem: that the sum of the squares of the two lines that form a right angle, must add up to the square of the hypotenuse (c). So 6²+8² is 100, which is the square of 10.

Answer:

10

Step-by-step explanation:

Pythagorean Theorem tells us that (6)a^2 plus (8)b^2 = (10)c^2

6^2 = 36

8^2 = 64

36 + 64 = 100

sqrt of 100 = 10

c = 10

Answer:

235.62

Step-by-step explanation:

First you need to find the area of the big circle as a whole the equation is

A = pir^2

you need to plug in the radius of the big circle which would be

A = pi(10)^2

which equals

314.16

Then you need to find the area of the unshaded circle in the middle using the same formula but replacing the 10 with a 5

which equals

78.54

We then subtract the 78.54 from the 314.16 and we get 235.62 which is the area of the shaded circle to the right

Answer:

$195 in total

Step-by-step explanation:

You would find the perimeter of the total garden first which equals 54 then times it by 1.5 and get 81 dollars for the gate. Then find the area of the triangle and get 120 then do 2 times 16 and get 32 then you add them together and get 152. Now with the 152 you divide it by 8 then multiple by 6 and finally add your 81 with 114 and get 195 dollars in total.

Answer:

[tex]y=8[/tex]

Step-by-step explanation:

Given the following question:

[tex](y-2)\div6=1[/tex]

To find the answer we must remember we need to isolate the variable and get it by itself, first we need to rewrite the expression and solve by using inverse of operations.

[tex](y-2)\div6=1[/tex]
[tex]\frac{(y-2)}{6} =1[/tex]
[tex]6\times0=0[/tex]
[tex]1\times6=6[/tex]
[tex](y-2)=6[/tex]
[tex]-2+2=0[/tex]
[tex]6+2=8[/tex]
[tex]y=8[/tex]

Your answer is "y = 8."

Hope this helps.

Answer:

[tex]27[/tex]

Step-by-step explanation:

We start by setting an equation.  We have [tex]2x+x+9=90[/tex] which simplifies to [tex]3x+9=90[/tex].  Subtract [tex]9[/tex] from both sides leaves us to solve for x when [tex]3x=81[/tex] divide by [tex]3[/tex] on both sides, we get [tex]x=27[/tex].

Answers:

1. 12m^2 and 8m^3

2. a=v+3, l=v-2

3. No

4. 4.5mm^2

Step-by-step explanation:

1. Surface area:

2m^2 (area of face) * 6 (# of faces)

=12m^2 or 12 square meters.

Volume: (2m)^3=8m^3 or 8 cubic meters.

2. a=v+3, l=v-2

because if we rewrote exactly what the problem says, "Anna is 3 years older than Vickie" that is mathematically a=v+3. Do the same with the other equation.

3. 5.275+8.36g when g=120 is 5.275+1003.2, or 6.278.2, which is more than 6000, so the bridge would not hold Melinda's truck and 120 gallons of water.

4. 2s^2 + 4sh when s=0.5mm and h=2mm:

2*0.25mm^2+4*0.5mm*2mm

Answer:

{A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}

Step-by-step explanation:

I took the test

The sample space of the compound event of spinning a spinner and tossing a six-sided number cube is {A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}, the cartesian product of the sample spaces of the two events. Hence, option A is the right choice.

An ordered set of sets is used to define a Cartesian Product. It's the collection of all conceivable ordered combinations made up of one member from each of the sets.

The set containing all ordered pairs (p, q), where p is an element of P and q is an element of Q, is the Cartesian product of two sets, P and Q, represented as P*Q.

We are given that a student spins a spinner that has 3 equal sections labeled A, B, and C and then tosses a six-sided number cube.

Let the event of getting something on spinner be X.

∴ Sample space of X = {A, B, C}

Let the event of getting something on the number cube be Y.

∴ Sample space of Y = {1, 2, 3, 4, 5, 6}

The sample space of the compound event is the cartesian product of sample space of X with sample space of Y.

∴ Sample space of compound event = {A, B, C}*{1, 2, 3, 4, 5, 6}

or, Sample space = {A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}.

∴ The sample space of the compound event of spinning a spinner and tossing a six-sided number cube is {A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}, the cartesian product of the sample spaces of the two events. Hence, option A is the right choice.

Answer:

12

Step-by-step explanation: this is because if the circle is 24 then half the circle should be 12 if not then I don’t know your on you own

The area of a normal full circle is given by;

[tex]a = \pi \: r {}^{2} [/tex]

but since i want a semi circle, i would want that area to be split into 2, right?

So our new equation for the area of a semi circle is given by;

[tex]a = \frac{\pi \: r {}^{2} }{2} [/tex]

where r is the radius of our semi-circle.

The radius is half the diameter, so the radius here would be 24/2 =12

[tex]a = \frac{\pi \times 12 {}^{2} }{2} = \frac{144\pi}{2} = 72\pi = 72 \times 3.14159... = 226.194[/tex]

Answer:

Let's find the area of the rectangle below since we are given lengths.

Formula for area of a rectangle:

a = w * l, where "w" is the width and "l" is the length

The width is 24 and the length is 8 yards, so let's multiply those;

a = 24 x 8

a = 192 square yards

Now that we have found one of the areas, let's find the triangle above.

Though we are not given the base of the triangle, we can find the triangle's base by adding the other two side lengths beside it and subtract it by the total width.

The other two side lengths are 6 and 6, the total width is 24 as shown under the rectangle.

So we add the two side lengths (6 + 6) = 12, and subtract it from it's total, 24, (24 - 12) = 12

Now that we have found the base of the triangle, we must find the height of the triangle (the dotted line that runs vertically through the triangle).

The height of the rectangle is 8, the total of the dotted line that runs through both the triangle and the rectangle is 16.

Now we just subtract 8 from the total of the dotted line to get our height of the triangle, (16 - 8) = 8, finally we can find the area of the triangle.

Formula for area of triangle;

A = BH x 1/2, where "b" is the base and "h" is the height.

Replace b and h:

A = 12(8) x 1/2

A = 96 x 1/2

A = 96/2

A = 48 square yards

Since we found the area of the two shapes, we must add them to get the total area.

Area of rectangle: 192

Area of triangle: 48

We add;

192 + 48 = 240 square yards, is your answer.

Answer:

C. y=3/4x-3

Slope: 3/4

y-intercept: -3

Equation: y=3/4x-3

Make a table with x and y just like the one shown below

X:Y

0:-3

4:0

As you can see when x is 0 y equals (-3)

That (-3) is your y-intercept

Now we're going to save that for later

Then you do 0-(-3) and 4-0

You should get positive numbers of 3 and 4

Now you do y/x and that will be 3/4

That 3/4 is your slope

We're going to bring back that (-3) we got earlier and make the equation

The equation is y=3/4x-3

Make sure that you check your work as well

I hope you understand what I'm saying here :)

Answer:

#1 1/4

#2. 8/27

#3 3/4

Step-by-step explanation:

let the side of the square be y

Area of a square = y x y = y^2

y^2 = 1/16

y = sqrt (1/16)

y = 1/4

volume of a cube = edge length x edge length x edge length

Volume of a cube = 2/3 * 2/3 * 2/3

Volume of a cube = 8/27

volume of a cube = (edge length)^3

Edge length = cube root (volume of a cube)

Edge length = cube root (27/64)

Edge length = 3/4
