Answer:

− (8b − x) (5b + x)

Step-by-step explanation:

the following statement is true

Answer:

Fourth one

Step-by-step explanation:

You can find the x coordinate of the vertex (which is the axis of symmetry)

  by calculating    x =    - b/ 2a  

 ( when equation is arranged into   y =   a x^2 + bx + c    form  )

     first one   - -2/4  = 1/2

     second one   -2/ -4  = 1/2

        third one  - -2 / 4    = 1/2

          fourth one   - 2 / 4   = - 1/2   BINGO !

The answer would be [tex]\frac{1}{2}[/tex].

The probability of getting a 5 is [tex]\frac{1}{100}[/tex] and the probability of getting a number larger than 50 is [tex]\frac{49}{100}[/tex] (the 50 doesn't count). Add those up and you get [tex]\frac{50}{100}[/tex] and can be simplified to [tex]\frac{1}{2}[/tex].

Answer:

  51/100

Step-by-step explanation:

The probability is the ratio of the number of outcomes of interest to the total number of possible outcomes.

__

There is one number 5. There are 50 numbers in the range 1–100 that are greater than 50. So, the total number of outcomes of interest is 1+50 = 51.

The possible outcomes are any of the numbers 1–100, so there are 100 of them.

The probability of interest is ...

  P(n=5||n>50) = 51/100

Answer:

Step-by-step explanation:

let K be the cost of a knife

    S Ben the cost of a spoon

The statement “a knife is four times the cost of a spoon”

means  K = 4S

means  S = (1÷4)K

the statement “12 spoons and 16 knives cost £105.64”

means  12S + 16K = 105.64

⇔ 12(1÷4)K + 16K = 105.64

⇔ 3K + 16K = 105.64

⇔ 19K = 105.64

⇔ K = 105,64÷19

       = £5.56

your answer would be A. 122/27

Answer:

Surface Area: 5440

Step-by-step explanation:

Volume: 25600

Surface Area: 5440

Work Volume

V = lwh

V = (32)(40)(20)

V = 25600

Work Surface Area

A = 2(wh + lw + lh)

A = 2( 40(20) + 32(40) + 32(20) )

A = 2(800 + 1280 + 640)

A = 2(2720)

A = 5440

The diagonal : 54.99

Answer:

m∡ABC=140º

Step-by-step explanation:

Answer:

  200 cm²

Step-by-step explanation:

The scale factor for areas of similar figures is the square of the scale factor relating their linear dimensions. For volumes of similar figures, the scale factor is the cube of the linear dimension scale factor. Together, these relations mean the area scale factor is the 2/3 power of the area scale factor.

__

The larger surface area is ...

  (50 cm²) × 8^(2/3) = (50 cm²) ×4 = 200 cm²

_____

Additional comment

The linear dimension scale factor is the cube root, or 1/3 power, of the volume scale factor. The area scale factor is the square of that or the 1/3 power times 2, the 2/3 power.

  sf = ∛(v2/v1) = (v2/v1)^(1/3)

  a2/a1 = sf^2 = ((v2/v1)^(1/3))^2 = (v2/v1)^(2/3)

Answer:

$4,915.2

Step-by-step explanation:

(20% of 12,000 = 2,400 | 12,000 - 2,400 = 9,600)

(20% of 9,600 = 1,920 | 9,600 - 1,920 = 7,680)

(20% of 7,680 = 1,536 | 7,680 - 1536 = 6,144)

(20% out if 6,144 = 1,228.8 | 6,144 - 1,228.8 = 4,915.2)

Step-by-step explanation:

[tex]volume = \frac{4}{3} \times \pi {r}^{3} \\ = \frac{4}{3} \times 3.14 \times ( {10}^{3} ) \\ = 4186.666mm {}^{3} [/tex]

[tex]\large\boxed{\bold{Formula:V= \frac{4}{3}\pi{r}^{3}}}[/tex]

[tex]\large\boxed{\bold{\red\pi\red=\red3\red.\red1\red4}}[/tex]

In this question the radius is given so we'll simply have to substitute and solve.

Let's solve!

Instead of π we are asked to use 3.14

Substitute the values according to the formula.

[tex]V= \frac{4}{3}\times 3.14 \times {10}^{3}[/tex]

Calculator value:

[tex]\bold{V= 4186.666667 \: {mm}^{3}}[/tex]

Now, we have to round off to the nearest hundredth.

The value in the thousandths place is greater than 5 so we'll have to round up by adding 1 to the hundredths place.

Final answer:

[tex]\large\boxed{\bold{V= 4186.67 \: {mm}^{3}}}[/tex]

Hence, the volume of the given sphere is 4186.67 cubic millimeters.

GCF of 36 and 4   is    welllll,    just  4

so 36 - 4    =     4*9 - 4 =   4 ( 9-1)       ( I THINK that is what goes here)

Answer:

(- 2, 0 )

Step-by-step explanation:

5x - 4y = - 10 → (1)

- 4x + 5y = 8 → (2)

multiplying (1) by 4 and (2) by 5 and adding result will eliminate x

20x - 16y = - 40 → (3)

- 20x + 25y = 40 → (4)

add (3) and (4) term by term to eliminate x

9y = 0 , thus

y = 0

substitute y = 0 into either of the 2 equations and solve for x

substituting into (1)

5x - 4(0) = - 10

5x - 0 = - 10

5x = - 10 ( divide both sides by 5 )

x = - 2

solution is (- 2, 0 )

Answer: 3 [tex]\frac{1}{3}[/tex] liters

Step-by-step explanation:

     We will set up a proportion to help us solve.

[tex]\displaystyle \frac{10 \text{ liters of fruit juice}}{x\text{ liters of lemon soda}} =\frac{3 \text{ liters of fruit juice}}{1\text{ liters of lemon soda}}[/tex]

    Now we will cross multiply.

10 = 3x

    Lastly, we will divide both sides by 3.

3 [tex]\frac{1}{3}[/tex] = x

       She will need 3 [tex]\frac{1}{3}[/tex] liters of lemon soda.

Given that, Darlene can finish an average-sized crocheted centerpiece for 2 week, the number of days it will take her to finish 4 projects is  56 days.

Given that;

If 1 project takes 14 days

4 project takes x days

x = 4 × 14 days

x  = 56 days

Given that, Darlene can finish an average-sized crocheted centerpiece for 2 week, the number of days it will take her to finish 4 projects is  56 days.
