Answer:

The pole is 6 feet tall.

Step-by-step explanation:

The height makes the perpendicular and the shadow makes the base of the triangle in the given question

                                Pole                       Mary

Height                         x                            4

Shadows                    15                           10

If the height is taken along y- axis and shadow is taken along x axis

Then

tan alpha = Perpendicular/ base

for Mary    Tan alpha = 4/10

For the pole = tan alpha = x/15

Comparing      x/15= 4/10

x= 4*15/10= 60/10= 6

The pole is 6 feet tall.

Answer:

8x+5 + 2x+5 = 180

10x+10=180

10x =170 = x = 17

Step-by-step explanation:

Answer:

answer: x = 17 Hope this helps!

2 x 17 + 5 = 39 8 x 17 + 5 = 141

Straight angles are 180 degrees

39 + 141 = 180

So x = 17

The equation represents a circle is option (A) (x+2)^2 +(y-3)^2 = 72 is the correct answer.

A circle is a collection of all points in a plane which are at a constant distance from a fixed point. A circle is a round-shaped figure that has no corners or edges.

For the given situation,

The center of the circle, (h,k) = (-2,3)

The point on the circle, (x,y) = (4,-3)

The radius of the circle is

[tex]r=\sqrt{(h-x)^{2} +(k-y)^{2} }[/tex]

⇒ [tex]r=\sqrt{(-2-4)^{2} +(3-(-3))^{2} }[/tex]

⇒ [tex]r=\sqrt{6^{2}+6^{2} }[/tex]

⇒ [tex]r=\sqrt{72}[/tex]

The formula of equation of circle is

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

The circle has the center (h,k) = (-2,3) and radius is √72,

⇒ [tex](x-(-2))^{2}+(y-3)^{2}=(\sqrt{72} )^{2}[/tex]

⇒ [tex](x+2)^{2}+(y-3)^{2}=72[/tex]

Hence we can conclude that the equation represents a circle is option (A) [tex](x+2)^{2}+(y-3)^{2}=72[/tex] is the correct answer.

Answer:

10 months

Step-by-step explanation:

If it takes 2 months to do 1/5th, it will take 4 months to do 2/5, 6 months to do 3/5, 8 months to do 4/5, and 10 months to do 5/5 or in other words the whole thing.

The remaining work will take 8 month.

Algebra is the branch of mathematics that represents problems in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.

Given:

As,  1/5 th of the work has been completed in 2 months.

let the total time taken to complete the work is 'x' month.

1/5 * x = 2

x= 5*2

x=10 month

Hence, remaining work will take (10 - 2) = 8 month.

Answer:

1 /7

Step-by-step explanation:

Sample space =. (1, 2, 3, 4, 5, 6, 7, 8)

Odd numbers = (1, 3, 5, 7)

Probability of picking an odd number = number of odd numbers / sample space

P(odd number) = 4 / 8 = 1/2

Without replacement :

P(picking a 2) :

Sample space = 8 - 1 = 2

Hence,

P(picking a 2) = 2 / 7

P(picking an odd number and the a 2) =

1/2 * 2/7 = 2 /14 = 1/7

Answer:

19.3 years

Step-by-step explanation:

Given that the initial mass of a sample of Element X is 100 grams,

The formula is given as:

N(t) = No × (1/2) ^t/t½

Element X is a radioactive isotope such that every 30 years, its mass decreases by half.

N(t) = Mass after time (t)

No = Initial mass = 100 grams

t½ = Half life = 30 grams

N(t) = 100 × (1/2) ^t/30

How long would it be until the mass of the sample reached 64 grams, to the nearest tenth of a year?

This means we are to find the time

N(t) = 100 × (1/2) ^t/30

N(t) = 64 grams

64 = 100(1/2)^t/30

Divide both sides by 100

64/100 = 100(1/2)^t/30/100

0.64 = (1/2)^t/30

Take the Log of both sides

log 0.64 = log (1/2)^t/30

log 0.64 = t/30(1/2)

t = 19.315685693242 years

Approximately = 19.3 years
