Find the unknown side length, x.

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

Answer:

C; A

Step-by-step explanation:

(coming from an 8th grader :)

1. should be A, because on each side of the quadrilateral there are two lines being mirrored.

2. should be C, because the angles are acute and not right or straight. you may be thinking “but there is a straight line” yes, you are right there’s a straight line, but there’s multiple angles consisted in making one whole angle.

- 3y² - 7y + 6

Step-by-step explanation:

Given

(- 3y + 2)(y + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

- 3y (y + 3) + 2(y + 3) ← distribute both parenthesis

= - 3y² - 9y + 2y + 6 ← collect like terms

= - 3y² - 7y + 6

Answer:

212.5 cm² and 120 in²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

(4)

Here b = 25 and h = 17, thus

A = 0.5 × 25 × 17 = 212.5 cm²

(5)

Here b = 12 and h = 20, thus

A = 0.5 × 12 × 20 = 6 × 20 = 120 in²

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

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:

A. x = 5, -3

Step-by-step explanation:

The quadratic equation/formula is:

[tex]x = \frac{-b+- \sqrt{b^2 - 4ac} }{2a}[/tex]

The setup is:

[tex]ax^2+bx+c=0[/tex]

[tex]4x^2 - 8x -60=0[/tex]

Plug in the numbers according to the letter associated:

[tex]x = \frac{8+-\sqrt{-8^2-4(4)(-60)} }{2(4)}[/tex]

[tex]x = \frac{8+-\sqrt{1024} }{8}[/tex]

[tex]x = \frac{8+-32}{8}[/tex]

Solve for addition and subtraction:

[tex]x = \frac{8+32}{8}[/tex]                                                                              [tex]x = \frac{8-32}{8}[/tex]

[tex]x = \frac{40}{8}[/tex]                                                                                  [tex]x = \frac{-24}{8}[/tex]

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.

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: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
