Answer:

x= 8

Step-by-step explanation:

Sum of the two angles = 90

12x - 30 + 3x = 90

15x -30 = 90

15x = 90 + 30

15x = 120

x = 120/15 = 8

According to this formula, the time when the world population reach 8 billion is D. 2026.

From the information given, the capita growth rate of the world population continues to be what it was in the year 2016, the world population t years after July 1, 2016, will be 7.4 ✕ 1.011t billion.

Therefore, the year when the world population reach 8 billion will be:

80 billion = 7.4 × 1.011t billion

1.011t = 80/7.4

1.011t = 10.8

t = 10.8/1.011

t = 10

Therefore, the number of years will be added. This will be:

= 2016 + 10

= 2026

The equation of the line in standard form is 12x-2y=13.

Given that line that is the perpendicular bisector of the segment whose endpoints are R(-1, 6) and S(5, 5).

R≡(-1,6) and S≡(5,5)

The perpendicular bisector of the line segment joining R and S will pass through the midpoint M.

coordinate of M is =((-1+5)/2,(6+5)/2)

coordinate of M is=(2,11/2)

Slope of the line joining R and S is

m₁=(6-5)/(-1-5)

m₁=-1/6

We know that for two perpendicular lines having slope m₁ and m₂,

m₁m₂=-1

Here, m₁=-1/6

Let m₂ be the slope of the perpendicular bisector

(-1/6)m₂=-1

m₂=6

Equation of the perpendicular bisector will be,

(y-yₙ)/(x-xₙ)=m₂   [(xₙ,yₙ) is the coordinate of M]

(y-11/2)/(x-2)=6

(2y-11)/2=6(x-2)

2y-11=12x-24

12x-2y=13

Answer:

11.  17.7 units

12.  24.7 units

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.  

To find the perimeter of a polygon, sum the lengths of its sides.

Use the distance formula to find the length of each side.

[tex]\boxed{\begin{minipage}{4.7 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

Given points:

Use the distance formula to find the length of each side of ABC:

[tex]\begin{aligned}AB & = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& = \sqrt{(2-(-2))^2+(5-1)^2}\\& = \sqrt{4^2+4^2}\\& = \sqrt{16+16}\\& = \sqrt{32}\end{aligned}[/tex]

[tex]\begin{aligned}BC & = \sqrt{(x_C-x_B)^2+(y_C-y_B)^2}\\& = \sqrt{(5-2)^2+(1-5)^2}\\& = \sqrt{3^2+(-4)^2}\\& = \sqrt{9+16}\\& = \sqrt{25}\\& = 5\end{aligned}[/tex]

[tex]\begin{aligned}AC & = \sqrt{(x_C-x_A)^2+(y_C-y_A)^2}\\& = \sqrt{(5-(-2))^2+(1-1)^2}\\ & = \sqrt{7^2+0^2}\\ & = \sqrt{49}\\ & = 7\end{aligned}[/tex]

To find the perimeter, sum the sides:

[tex]\begin{aligned}\sf Perimeter & = AB+BC+AC\\& = \sqrt{32}+5+7\\& = 4\sqrt{2}+12\\& = 17.7\;\sf units\;(nearest\:tenth)\end{aligned}[/tex]

Given points:

After plotting the given points, it is clear that the polygon is a parallelogram. As the opposite sides of a parallelogram are equal in length:

Therefore, we only need to find the length of two sides to calculate the perimeter.

Use the distance formula to find AB and BC:

[tex]\begin{aligned}AB & = \sqrt{(1-(-3))^2+(6-5)^2}\\& = \sqrt{4^2+1^2}\\& = \sqrt{16+1}\\& = \sqrt{17}\end{aligned}[/tex]

[tex]\begin{aligned}BC & = \sqrt{(3-1)^2+(-2-6)^2}\\& = \sqrt{2^2+(-8)^2}\\& = \sqrt{4+64}\\& = \sqrt{68}\end{aligned}[/tex]

Therefore, the perimeter of ABCD is:

[tex]\begin{aligned}\sf Perimeter & = 2(AB+BC)\\& = 2(\sqrt{17}+\sqrt{68})\\& = 6\sqrt{17}\\& =24.7\;\sf units\;(nearest\:tenth)\end{aligned}[/tex]

The volume of a cuboid or box is the multiplication of length, width, and height by that expression the width of the given cuboid box is 10 inches.

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

The volume of cuboid = length × height × width.

Given that,

Height (H) = 9 inches.

The length is three inches more than the width.

So,

L = 3 + W

Now,

Volume of box = 1170 inches³

Now,

The volume of the cuboid is given as

V = L×W×H

1170 = (3 + W) × W×9

W² + 3W - 130 = 0

W² + 13W - 10W - 130 = 0

W(W + 13) - 10(W + 13) = 0

(W + 13)(W - 10) = 0

W = 10,-13 since the length can never be negative so 10 inches will be right.

Hence "The width of the given cuboid box is 10 inches".

Answer:

11.58 years

6.82 years

Step-by-step explanation:

Compound interest can be represented as: [tex]A=P(1+\frac{r}{n})^{nt}[/tex] where P = initial amount, r=interest rate, n=compounds in each time unit, t = time (usually years)

If you think about it the: [tex](1+\frac{r}{n}})^{nt}[/tex] represents the overall interest being applied to the principal amount.

This would have to be equal to 2, for it to be doubled, so let's set that equal to 2

[tex]2=(1+\frac{r}{n})^{nt}[/tex]

Now let's solve for "t", first let's take the log of both sides

[tex]log(2)=log([1+\frac{r}{n}]^{nt})[/tex]

Now let's use log properties, specifically the exponent one to rewrite

[tex]log(2)=nt *log(1+\frac{r}{n})[/tex]

Now divide both sides by the log(1 + r/n) and n

[tex]t=\frac{log(2)}{n*log(1+\frac{r}{n})}[/tex]

Our "n" is going to be the same for both equations, 12 since it's compounded monthly

The interest will be a bit different, but in the first case it will be 6% which is 0.06

[tex]t=\frac{log(2)}{12*log(1+\frac{0.06}{12})}[/tex]

simplifying this we get

[tex]t\approx11.581[/tex]

Rounding this we get: [tex]t=11.58[/tex]

Now let's do this to the other equation:

[tex]t=\frac{log(2)}{12*log(1+\frac{0.102}{12})}[/tex]

simplifying this we get:

[tex]t\approx 6.824[/tex]

Then According to Ben's graph it shows that he drove 250 miles at 5 hours while sally was at 100 miles for 5 hours. So Ben drove the farthest. Then finally for number 9 I concluded that sally is driving 15 miles per hour because distance always adds up by 15 miles.

The 3 device trackers and wireless charger purchased at $45.22 using a 15% discount coupon gives the price of one device tracker as $12.52

Number of device trackers = 3

The discount given by the coupon = 15% off the total purchase

Amount paid after using the coupon.= $45.22

Original price of the charger = $15.64

Let x represent the price of one device tracker, we have the following equation;

(1 - 0.15)×(3•x + 15.64) = 45.23

Which gives;
