d = 6

Step-by-step explanation:

5d - 10 = 20​

Add 10 to each side

5d - 10+10 = 20+10

5d = 30

Divide by 5

5d/5 = 30/5

d = 6​

Answer:

d = 6

Step-by-step explanation:

5d - 10 = 20

Add 10 to both sides of the equation

5d = 30

Divide both sides of the equation by 5

d = 6

Answer:

a = -32

Step-by-step explanation:

3a−(10+5a)=54

Distribute the minus sign

3a−10-5a=54

Combine like terms

-2a -10 = 54

Add 10 to each side

-2a-10+10 = 54+10

-2a = 64

Divide by -2

-2a/-2 = 64/-2

a = -32

Answer:

a = -32

Step-by-step explanation:

3a - (10 + 5a) = 54

Distribute the negative sign as if it were -1.

3a - 10 - 5a = 54

Combine like terms on left side.

-2a - 10 = 54

Add 10 to both sides.

-2a = 64

Divide both sides by -2.

a = -32

Answer:

They have the same domain and range.

Step-by-step explanation:

Since both are derived from the parent graph f(x) = √x, we know that the domain of the parent graph is [0, ∞) and the range is also [0, ∞). Since both graphs are only being modified by vertical stretch/shrink, they still have the same domain and range as the parent graph. Therefore, both graphs have the same domain and range.

Answer:

They have the same domain and range

Step-by-step explanation:

they're both in the first quadrant

Answer:

405.

Step-by-step explanation:

First term = a1

5th tern = a1 r^4

So a1r^4 - a1  = 400       r = 3 so:

3^4 * a1 - a1 = 400

a1(81-1) = 400

80a1 = 400

a = 5

Therefore the fifth term =  5* 3^4

= 405.

The first term and fifth term of Geometric progression will be 5 and 405, respectively.

Let a₁ be the first term and r be the common ratio.

Then the nth term of the geometric sequence is given as,

aₙ = a₁ · (r)ⁿ⁻¹

The common ratio of a g.p is 3. given that the 5th term is greater than the first term by 400. Then the equation is given as,

a₅ - a₁ = 400           ...1

a₅ = a₁ · 3⁴              ...2

From equations 1 and 2, then we have

81a₁ - a₁ = 400

80a₁ = 400

a₁ = 5

Then the value of the fifth term is given as,

a₅ = a₁ · 3⁴

a₅ = 5 x 81

a₅ = 405

The first term and fifth term of Geometric progression will be 5 and 405, respectively.

Answer:

B. -1/3x

Step-by-step explanation:

Start with

y = mx + b

The y-intercept is 0, so we have

y = mx

To find m, the slope, start at (0, 0).

slope = m = rise/run

Go up 1 unit and left 3 units. Rise = 1; run = -3.

m = 1/(-3) = -1/3

Now we have

y = -1/3x

2. 6/14

3. 12/20

4. 4/12

5. 5/11

Step-by-step explanation:

color of ball your looking for/Total amount of balls

Probability for the situations given are 1. 6/21, 2. 3/7, 3. 3/5, 4. 1/3 and 5. 5/11.

Probability is the chance of getting an outcome for an event. Probability is calculated by dividing the number of likely outcomes by the total number of outcomes.

1. Number of red balls = 15

  Number of blue balls = 6

  Total number of balls = 15 + 6 = 21

  Probability of getting a blue ball = 6/21

2. Number of white balls = 6

   Number of red balls = 8

   Total number of balls = 6 + 8 = 14

   Probability of getting a white ball = 6/14 = 3/7

3. Number of red balls = 12

   Number of blue balls = 8

   Total number of balls = 20

   Probability of getting a red ball = 12/20 = 3/5

4. Number of blue balls = 4

   Number of red balls = 8

   Total number of balls = 12

   Probability of getting a blue ball = 4/12 = 1/3

5. Number of blue balls = 6

   Number of black balls = 5

   Total number of balls = 11

   Probability of getting a black ball = 5/11

Hence the probabilities of selecting a ball at random in each case has been answered.

You can expand it in a simplier way using :

[tex] {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]

So for this question :

[tex] {(5x + 7)}^{2} \\ = {(5x)}^{2} + 2(5x)(7) + {(7)}^{2} \\ = 25 {x}^{2} + 70x + 49[/tex]

Answer:

B. 25x^2+70x+49

Step-by-step explanation:

To multiply we can use a method called FOIL. In this method, we multiply the first terms of each binomial, then the outer terms (first and last), then the inner terms (2nd and 3rd), and finally the last terms (2nd and last). The two binomials in this case are (5x+7)(5x+7).

So this means we first multiply 5x*5x, then 5x*7, then 7*5x, and finally 7*7. Multiplying these out we get 25x^2 + 35x + 35x +49. Finally, combining like terms we get 25x^2+70x+49, which is our answer.

x=8.4

Step-by-step explanation:

4x +8y=40

replace y as 0.8

4x+8*0.8=40

4x+6.4=40

subtract 6.4 from both sides

4x=33.6

divide by 4

x=8.4

Step-by-step explanation:

4x + 8y = 40

Simplify the equation

Divide all terms by 4

We have

x + 4y = 10

Make x the subject

x = 10 - 2y

When y = 0.8

Substitute the value of y into the equation

We have

x = 10 - 2(0.8)

x = 10 - 1.6

x = 8.4

Answer:

Option (C) 235.5 cubic units

Step-by-step explanation:

Data obtained from the question include:

Radius (r) = 5 units

Height (h) = 9 units

Pi (π) = 3.14

Volume (V) =..?

The formula for calculating the volume of an oblique cone is the same as the formula for calculating the right cone. The formula is given below:

V = 1/3πr²h

With the above formula, we can obtain the volume of the oblique cone as follow:

V = 1/3πr²h

V = 1/3 x 3.14 x 5² x 9

V = 3.14 x 25 x 3

V = 235.5 cubic units.

Therefore, the volume of the oblique cone is 235.5 cubic units.
