Answer:

B

Step-by-step explanation:

I used the quadratic formula

Answer:

B

Step-by-step explanation:

Given

(x + 5)² = 48 ( take the square root of both sides )

x + 5 = ± [tex]\sqrt{48}[/tex] = ± [tex]\sqrt{16(3)}[/tex] = ± 4[tex]\sqrt{3}[/tex] ( subtract 5 from both sides )

x = - 5 ± 4[tex]\sqrt{3}[/tex] → B

The letters M,S,V are the original image.

The letters M’, S’, V’ are the displayed image.

You can see that M’, S’,V’ is a smaller image, so it was a reduction.

The length of line MS is 9 units.

The length of M’S’ is 6 units.

The dialation is 6/9 = 2/3

Answer:

(a) reduction

(b) 2/3

Step-by-step explanation:

(a) The original figure is called ΔMSV, while the dilation is called ΔM'S'V'. Because we can see that M'S'V' is clearly much smaller than MSV, we know that the image is a reduction of the original.

(b) We simply need to find the ratio of one side of M'S'V' to one side of MSV. Look at M'S': the length is just 4 - (-2) = 6 (this is because it's a completely horizontal line). The length of MS is 6 - (-3) = 9.

So, the scale factor is: 6 / 9 = 2/3.

Answer:

r = 11

Step-by-step explanation:

Given

The above table

y = rx

Required.

Find the constant of proportionality.

To find the constant of proportionality, we simply test the values of y and x in the given formula.

Using y = rx

Make r the subject of formula by dividing both sides by x

y/x = rx/x

y/x = r

r = y/x

From the above table of data;

When x = 2, y = 22

So, r = 22/2

r = 11

When x = 7, y = 77

So, r = 77/7

r = 11

When x = 9, y = 99

So, r = 99/9

r = 11

Notice that r maintains the value of 11 all through.

Hence, the constant of proportionality, r for the above data is 11

r = 11

Answer:

312π mm3

Step-by-step explanation: yes

The required volume of the composite figure of the sphere on the top of the cone is 312π mm³. Option c is correct

The sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters. The volume of the composite figure is to determine.

Volume is defined as the ratio of the mass of an object to its density.

Volume of composite figure =  Volume of semi-sphere  + Volume of cone
                                              =   2/3πr³ + 1/3πr²h
                                              =  2/3*6³π + 1/3*6²*14π
                                              =   312π mm³

Thus, the required volume of the composite figure of the sphere on the top of the cone is 312π mm³.

Answer:

24 meters

Step-by-step explanation:

Alright. Your question had errors, but I managed to scramble together some answers.

The right triangle has a total of 3 sides, 2 which are 8 and 6. We need to find the hypotenuse.

Let's use the Pythagorean Theorum.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = 100

To get c by itself, square root it.

[tex]\sqrt{100} =10[/tex]

You found the hypotenuse :D

Add it up!

8 + 6 + 10 = 24 meters

Answer:

Remember this formula.

Step-by-step explanation:

[tex]\sqrt{a^{2}+b^{2}=c^{2}[/tex]

If your legs are 8 and 6, the last side is the hypotenuse, which is always the largest side of a right triangle. You calculate it's length by taking the measurements of leg A and leg B, and squaring both of them, or raising them both by the power of 2.

This will equal C, or your hypotenuse, but it will be squared, so you have to find its square root to get the actual measurement, which is why the equation has a square root sign over it, so the answer is automatically squared when put into a calculator.

8 x 8 = 64 [or [tex]8^{2}[/tex]]

6 x 6 = 36 [or [tex]6^{2}[/tex]]

[tex]8^{2}+6^{2}=100\\\sqrt{100}=10[/tex]

[tex]\sqrt{8^{2}+6^{2}=10[/tex]

Answer:

9.5

Step-by-step explanation:

Well the constant proportionality is 9.5 because that is what makes p directly proportional to a, because when h increases, a increases, and when h decreases, a decreases.

Answer:

i think its 25 because like if 72 is the shaded part then it can't be the answer 100 wouldn't be the answer because it is too high and 20 wouldn't be the answer because it is too low so 25 is my reasonable answer.

Step-by-step explanation:

Since the area to me is 25 then we would do 360 x 25 = 9000

the you do 9000 / 36 i got 36 by doing 360 / 10

After that you you do 9000 / 36 which gives you 2.5

Last i did 2.5 x 10 which gave me 25

Answer:27.7

Step-by-step explanation:

the formula for a cone is V=1/3πr*2h

it is 1/3 because a cone is one-third of a sphere.

you then put the information from the text in the formula and you get this

V=1/3x 3.14 (pi) x 2.1 to the power of 2 (radius is half of a diameter)x 6 (height)

then you get the answer 27.6948

round to the nearest 10th and you get

A. 27.7

Also, I took the test.

There are 27.77 in³ of frosting is in the bag.

The amount of space, measured in cubic units, that an object or substance occupies.

Given that, To apply frosting to a cake, a baker twists a plastic bag containing the frosting into a cone shape with a diameter of 4.2 inches and a length of 6 inches.

Volume of cone = ¹/₃πr²h

r = 4.2/2 = 2.1 in

h = 6 in

Volume = ¹/₃x2.1x2.1x6

= 27.77

Hence, the volume of the cone is 27.77 in³

Step-by-step explanation:

Answer:

t = 2 1/6

1/5 t + 2/5 = 5/6

Step-by-step explanation:

1/5 (t + 2) = 5/6

Multiply each side by 5

t+2 = 5*5/6

t+2 = 25/6

Subtract 2 from each side

t+2 -2 = 25/6 -12/6  ( using the same denominator)

t = 13/6 = 2 1/6

We can also distribute

1/5 t + 2/5 = 5/6

Subtract 2/5 from each side

1/5t = 5/6 -2/5

Get a common denominator

1/5t =25/30 - 12/30

1/5t = 13/30

Multiply each side by 5

t = 13/30 *5

t = 13/6

ANSWER : t = 2 1/6

1/5 t + 2/5 = 5/6

Step-by-step explanation:

1/5 (t + 2) = 5/6

Multiply each side by 5

t+2 = 5*5/6

t+2 = 25/6

Subtract 2 from each side

t+2 -2 = 25/6 -12/6

t = 13/6 = 2 1/6

We can distribute

1/5 t + 2/5 = 5/6

Subtract 2/5 from each side

1/5t = 5/6 -2/5

Get common denominator

1/5t =25/30 - 12/30

1/5t = 13/30

Multiply each side by 5

t = 13/30 *5

t = 13/6
