Change 0.069 to a percent

Mathematics
2 answers:
DIA [1.3K]4 years ago
7 0

Answer:

6.9%

Step-by-step explanation:

We have to convert 0.069 to a percent.

When we convert any decimal number to a percent, we have to multiply the number to 100 and then put a mark of percentage or we can move the decimal point two place to the right.

so 0.069 × 100 = 6.9%

Therefore answer would be 6.9%

A new parabola, g(x), is translated from f(x) using the translation T(-3, 7).
andriy [413]

Answer:

We can predict the vertex point of g(x) by vectorial sum, which is equal to V_{G}(x,y) = (h - 3, k + 7).

Step-by-step explanation:

The vertex of g(x) is equal to the vectorial sum of the vertex of f(x) and the translation vector:

V_{G}(x,y) = V_{F}(x,y) + T(x,y) (1)

Where T(x,y) is the translation vector.

If we know that V_{F} (x,y) = (h,k) and T(x,y) = (-3, 7), then the formula for the vertex of g(x) is:

V_{G}(x,y) = (h,k) +(-3, 7)

V_{G}(x,y) = (h - 3, k + 7)

Suppose a publishing company estimates that its monthly cost is C(x) = 600{x^2} + 300xC(x)=600x 2 +300x and its monthly revenue
Leto [7]

Answer:

the answer is A,

P(x) = -0.4x³+100x²-900x+500

Step-by-step explanation:

monthly cost:

c(x) = 600x {}^{2}  + 300x

monthly revenue:

r(x) =  - 0.4 {}^{3}  + 700x {}^{2}  - 600x + 500

profit function:

p(x) = r(x) - c(x)

p(x) = ( - 0.4x {}^{3}  + 700 {x}^{2} - 600x + 500) - (600x {}^{2}   + 300x)

i) remove the first bracket

p(x) =  - 0.4x {}^{3}  + 700x {}^{2} - 600x + 500 - (600 {x}^{2}   + 300x)

ii) there is a negative sign, '-' in front of the second bracket. so, change the sign of each term of the expression inside the bracket

p(x) =  - 0.4x {}^{3}  + 700 {x}^{2}  - 600x + 500 - 600x {}^{2}  - 300x

iii) collect like terms

p(x) =  - 0.4x {}^{3}  + 700 {x}^{2}  - 600 {x}^{2}  - 600x - 300x + 500

iv) simply the like terms

p(x) =  - 0. 4{x}^{3}  + 100 {x}^{2} - 900x + 500

Since the area of the circle is I the area of the square, the
Dovator [93]

Answer:

(b)

V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}] or V_2 = \frac{1}{3}\pi r^2h

Step-by-step explanation:

Given

Ratio = \frac{\pi}{4}

See attachment for complete question

Required

Determine the volume of the cone

The volume of a square pyramid is:

V = \frac{a^2h}{3}

Where

a = base dimension

From the attachment, the base dimension of the square pyramid is 2r.

So:

a = 2r

The volume becomes;

V = \frac{(2r)^2h}{3}

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.

So, we have:

V_2  = Ratio * V

V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]

V_2 = \frac{\pi}{4} * \frac{(2r)^2h}{3}

Open bracket;

V_2 = \frac{\pi}{4} * \frac{4r^2h}{3}

Cancel out 4

V_2 = \pi * \frac{r^2h}{3}

The above can be written as:

V_2 = \frac{1}{3} * \pi r^2h

V_2 = \frac{1}{3}\pi r^2h

So, we have:

V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]

or

V_2 = \frac{1}{3}\pi r^2h

The work of a student to solve the equation 3(2x − 4) = 8 + 2x + 6 is shown below:
Alexeev081 [22]

Answer:

The student made the error at step 2.

Step-by-step explanation:

The correct step will be:

Step 2; 6x − 12 = 14 + 2x

As 3 will be multiplied with 2x and 4 which will give 6x − 12
