Which fraction is a name for the point that is labeled with the question mark on the number line?
A) 4/8
B) 3/4
C) 1/4
D) 2/4

Answer:

solutions at -1 and 11

Step-by-step explanation:

(-b ± √b²-4ac) / 2a

in this problem, a = 1, b = -10, c = -11

(10±√100-4(-1)(-11)) / 2(1) =

(10 + √144) / 2 = 22/2 = 11

(10 - √144) / 2 = -2 / 2 = -1

Answer:

Step-by-step explanation:

Amount she gets in a day = number of flower * cost of each flower

                   = (25x² +5x + 5)*5x

                  = 25x²*5x + 5x *5x  + 5*5x

                  = 125x³ + 25x² + 25x

Amount she gets in 5 day = (125x³ +25x² + 25x)* 5

                                           = 125x³*5 + 25x² *5 + 25x *5

                                          = 625x³ + 125x² + 125x

Answer:

Width = 12

Step-by-step explanation:

L = k/w

Where,

L = length of the rectangle

w = width of the rectangle

k = constant of proportionality

length is 2 and the width is 42

L = k/w

2 = k/42

k = 42 × 2

k = 84

calculate the width of a rectangle whose length is 7.

L = k/w

7 = 84/w

7w = 84

w = 84/7

w = 12

Width = 12

Answer:

sin(θ) = 0.86602540378

Step-by-step explanation:

To find the value of theta, we need to find do the acos of it

θ = acos(1/2)

θ = 60

and then you find sin(60)

sin(60) = 0.86602540378

Answer:

Part A

The surface area of the solid is 408 cm²

Part B

The volume of the solid is 312 cm³

Step-by-step explanation:

Part A

The surface area of the figure is found by finding the sum of the surface area of the individual rectangles that make up the figure as follows;

The areas of the rectangles are;

A₁ = 6 cm × 2 cm = 12 cm²

A₂ = 6 cm × 4 cm = 24 cm²

A₃ = 6 cm × 6 cm = 36 cm²

A₄ = 12 cm × 6 cm = 72 cm²

A₅ = 2 × 6 cm × 2 cm = 24 cm²

A₆ = 2 × 8 cm × 2 cm = 32 cm²

A₇ = 8 cm × 2 cm = 16 cm²

A₈ = 10 cm × 6 cm = 60 cm²

A₉ = 2 × 12 cm × 2 cm = 48 cm²

A₁₀ = 6 cm × 2 cm = 12 cm²

A₁₁ = 12 cm × 6 cm = 72 cm²

The area, A = A₁ + A₂ + A₃ + A₄ + A₅ + A₆ + A₇ + A₈ + A₉ + A₁₀ + A₁₁

Therefore, A = (12 + 24 + 36 + 72 + 24 + 32 + 16 + 60 + 48 + 12 + 72) cm² = 408 cm²

The surface area of the solid, A = 408 cm²

Part B

The volume is found similarly as follows;

V₁ = 6 cm × 6 cm × 2 cm = 72 cm³

V₂ = 8 cm × 6 cm × 2 cm = 96 cm³

V₃ = 12 cm × 6 cm × 2 cm = 144 cm³

The volume of the solid figure, V = V₁ + V₂ + V₃

∴ V = (72 + 96 + 144) cm³ = 312 cm³

The volume of the solid figure, V = 312 cm³.

Answer:

y=-x-8

Answer:

6

Step-by-step explanation:

ok

Lets start by grouping like terms

we get

-5x=-30

divide -5 from both sides

x=6

Answer:

x = 6 or C) 6

Step-by-step explanation:

Step 1: We will subtract 2x from both sides.

−3x + 6 − 2x = 2x − 24 − 2x

To understand a bit better: -3x - 2x = -5x and 2x - 2x = 0 so it will end up looking like this:

−5x + 6 = −24

Step 2: We will subtract 6 from both sides.

−5x + 6 − 6 = −24 − 6

−5x = −30

Step 3: We will divide both sides by -5.

−5x/−5 = −30/−5

Both will equal to positive 6 so it is your x, I hope this somewhat helped you better understand the equation!

Answer:

what is the picture????

Answer:

24 days

Step-by-step explanation:

120 students =30 days

120+30 =150 students

MORE/LESS METHOD

120 students (a) : 30 days(y)

150 students (b) : x

Find the value of x using the formula: a/b × y

If you think the value of x will be more than y then the bigger number will be the numerator. If u think x will be less, then the smaller number will be in the numerator.

I predict that x will be less than y

THEREFORE... 120/150 ×30

= 24 days

Answer:

first find the gradient:

M;=∆y/∆x

hence;M=7_2/3_2=5/1

M=5

substituting in equation

y=mx+c take point (3,7) and point (x,y)

y-7/x-3=5

y-7=5(x-3)

y_7=5x_15

y=5x-15+7

y=5x-8

Answer:

10218.75

Step-by-step explanation:

You should divide the two shapes into a rectangle and a triangle, find the area of each, then add them together like so:

For the rectangle:

37.5*22.5 = 843.75

For the triangle:

To find the base: 75 - 37.5 = 37.5

To find the height, use pythagoream theorem.

62.5² = 37.5² + b²

3906.25 = 1406.25 + b²

3906.25 - 1406.25 = 2500

√2500 = 50.

The height is 50, so 50*37.5(1/2)

= 937.5

Now add them together

937.5 + 843.75

Answer:

32.4mm²

Step-by-step explanation:

area of triangle =

1/2 × base × height "or" ( base × height ) ÷ 2

base= 12mm

height= 5.4mm

(12mm × 5.4mm) ÷ 2

= 32.4mm²

Answer:

7 in

Step-by-step explanation:

volume of a rectangular prism = width x height x length

width x length = area of the base

the sea shell box

200 = width x length x 5

width x length = 200/5 = 40cm^2

rock box

280 = 40in^2 x height

height = 280/40 = 7 in

Answer:

See Below.

Step-by-step explanation:

We are given that ABC is a triangle in which AB = AC.

A circle passing through B and C also intersects the sides AB and AC at points D and E respectively.

And we want to prove that AD = AE.

By the secant-secant theorem (shown below), we know that:

[tex]AD(AB)=AE(AC)[/tex]

We are given that AB = AC. So, by substitution:

[tex]AD(AB)=AE(AB)[/tex]

And by dividing both sides by AB (AB ≠ 0), we acquire:

[tex]AD=AE[/tex]
