Answer:

Step-by-step explanation:

-6n + 2.9 = 11

subtract 2.9 from both sides

-6n = 8.1

divide both sides by -6

n = -1.35

2/3n - 3 = 8

add 3 to both sides

2/3n = 11

multiply both sides by 3

2n = 33

divide both sides by 2

n = 16.5

hope this helps <3

Answer:

left side:

-6n = 11 - 2.9

-6n = 8.1

n = - 8.1/6

n = - 1.35

right side:

2/3 n = 8 + 3

2/3 n = 11

n = 33/2

n = 16.5

What is Future Value?

A financial concept known as future value (FV) assigns a value to an asset based on anticipated factors like future interest rates or cashflows. Knowing how much their investment would be in five years, given a projected rate of return, may be valuable for an investor.

We have,

P= $1000

R= 5%

T= time in years

We know that amount

A(t) = P(1 + R/100[tex])^t[/tex]

So, V(t) = 1000 (1+ 5/100[tex])^t[/tex]

Thus, the required function is  V(t) = 1000 (1+ 0.05[tex])^t[/tex]

Y la pregunta?

Suppose a blue car is 1/2 mile south of an intersection, driving north towards the intersection at 40 mph (miles per hour). At the same time, a red car is 1/2 mile east of the intersection, driving east (away from the intersection) at an unknown speed. The the straight-line distance between the blue and red car is increasing at a rate of 15 mph. What is the speed of the red car?

Answers

Answer:

dx/dt  = - 18,79 mph

Step-by-step explanation:

The two cars with the intersection point and the straight-line distance between the cars make up a right triangle. In that right triangle, the legs are the distance between each car and the intersection point, and the distance between cars is the hypothenuse

If we call  x  and  y  distances between blue car and red car respectively  and L the hypothenuse by Pythagoras theorem we have:

L²  =  x²  + y²      (1)

Tacking derivatives on both sides of the equation

2*L*dL/dt  = 2*x*dx/dt + 2*y*dy/dt

And from equation (1)

L²  = (0,5)² + (0,5)²    ⇒  L = √(0,5)²  + (0,5)²   ⇒ L = 0,5*√2

By subtitution in equation (2)

2*(0,5*√2)*15 = 2*0,5*dx/dt + 2*0,5*40

(15*√2 - 40 ) / 1  = dx/dt  [mph]

dx/dt  = - 18,79 mph

Note the( - ) sign is equivalent to say that the car is driving away from the intersection point

Solving the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex] we get [tex]\sqrt{21}-2\sqrt{7}[/tex]

Step-by-step explanation:

We need to solve the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex]

We know that [tex]\sqrt{x} = x^{\frac{1}{2}}[/tex]

Solving:

[tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}\\=((\sqrt{21}-2\sqrt{7} )^2)^\frac{1}{2}[/tex]

We know that [tex](a^2)^\frac{1}{2}=a[/tex]

x = 27

Step-by-step explanation:

m<X + m<XWY + m<XYW = 180    (measures of <s of triangle add to 180)

m<X = 90

90 + m<XWY + m<XYW = 180

m<XWY + m<XYW = 90     Equation 1

m<XWY + m<VWY = 180      (linear pair)     Eq. 2

m<XYW + m<ZYW = 180      (linear pair)     Eq. 3

Add Eqs 2 & 3

m<XWY + m<VWY + m<XYW + m<ZYW = 360

m<XWY + m<VWY + m<XYW + m<ZYW = 360

According to Eq. 1, m<XWY + m<XYW = 90.

90 + m<XYW + m<ZYW = 360

Also, m<VWY = 6x & m<ZYW = 4x

90 + 6x + 4x = 360

10x = 270

please help meeee the blue line is what I have to find please show your work​

Answers

Answer:

So we have to satisfy the equation so let us simplifyLet the empty space be n N-16+4n+9+1= 10n-6 N-4n=10nn=14n So the missing value is 14N to statify the equation
Let the blue line equal to n

So now the equation is n-16+4n+10=10n-6

Collect like terms

5n-6= 10n-6

Move 6 to the other side as a positive

5n=10n

Move 10n to the other side as a negative

5n-10n=0

-5n=0

Divide both sides by -5

So, n is equal to 0

A regular hexagon has an area of 750.8cm². The side length is 17cm. Find the apothem.

A. 7.4cm
B. 14.7cm
C. 21.5cm
D. 88.3cm

Answers

The formula for determining the apothem of regular hexagon is s/2tan(180/n) , where 's' is any side length of regular hexagon and 'n' is the number of sides of regular hexagon.
So, apothem = 17/2tan(180/n)
= 17/2tan(30)
= 17/1.15
= 14.78 units
Therefore, the measure of apothem of the regular hexagon is 14.7 units.

A taxi charges a flat rate of $1.75, plus an additional $0.65 per mile. Erica has at most $10 to spend on the cab ride. How far can Erica travel?

Answers

Answer:

x = 12.7 or x ≈ 12

Step-by-step explanation:

1.75 + 0.65x = 10

0.65x = 10 - 1.75

0.65x = 8.25

x = 8.25 / 0.65

x = 12.7

x ≈ 12

[tex]5\sqrt{5}\left(ab\right)^{\frac{3}{2}}[/tex]

Writing the expression as a radical

But, let us revise some rules:

[tex]\sqrt{a}=a^{\frac{1}{2}}[/tex]

[tex]\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

[tex]\left(a\cdot \:b\right)^n=a^nb^n[/tex]

let us solve now

[tex]5\sqrt{5}\left(ab\right)^{\frac{3}{2}}[/tex]

[tex]=5^{\frac{3}{2}}\left(ab\right)^{\frac{3}{2}}[/tex]         ∵  [tex]\:5^{\frac{3}{2}}=5\sqrt{5}[/tex]

[tex]=\left(5ab\right)^{\frac{3}{2}}[/tex]

[tex]=\left(5ab\right)^{3\cdot \frac{1}{2}}[/tex]

[tex]=\left(\left(5ab\right)^3\right)^{\frac{1}{2}}[/tex]

[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt{a}=a^{\frac{1}{2}}[/tex]

Hailey is 2 years younger than her sister. If Hailey is h years old, which equation represents the age of her sister, s?

Answers

Answer:

S=H+2

Step-by-step explanation:

OK, so hailey is the variable H. And she is 2 years younger than her sister.

What is the age of her sister?

So we know it has to be, hailey's age + something? = age of her sister.

what is that +something? it's the number "2 years younger" so hailey's age; which is h, plus 2 is equal to her sister's age.

H+2=S

OK, why do we need to add 2? instead of minus two? Because hailey is 2 years younger than her sister, so you want hailey's age. If you were to minus 2, you'd be thinking that hailey is OLDER than her sister. Because if you want to her sister's age, you would have to SUBTRACT 2 because you are OLDER than her. So if you are younger than the sister, you would add to get your sister's age.

Answer:

S=H+2

Step-by-step explanation:

I got it right and that all that matters.
