Answer:

37.50 square centimeters

Step-by-step explanation:

The computation of the area of the sector is as follows:

As we know that

Area of the circle is

= πr^2

Since the radius is 10 cm so the area of total circle is

= 3.14 × 100

= 314

Also it is 360 degrees  

So, the area of the sector is

= 135 ÷ 360 × 1200

= 37.50 square centimeters

Answer:

The distance of Jack's father's work from home is 22.5 miles.

Step-by-step explanation:

Given;

time it takes Jacks father at usual speed, t = 30 minutes = 0.5 hour

Jacks father speed when traffic is bad, = 30 mph slower

let the usual speed = v

let the distance of Jack's father's work from home = y

When traffic is normal;

[tex]v = \frac{y}{0.5 } ---- equation \ (1)[/tex]

When traffic is bad;

[tex]v - 30 \ mph = \frac{y}{1 \ + \ 0.5} \\\\v -30 = \frac{y}{1.5} \\\\v= 30 +\frac{y}{1.5} ----equation \ (2)[/tex]

Solve equation (1) and (2) together;

[tex]\frac{y}{0.5} = 30 \ + \ \frac{y}{1.5} \\\\y = 0.5(30 \ + \ \frac{y}{1.5})\\\\y = 15 + \frac{y}{3} \\\\y - \frac{y}{3} = 15\\\\\frac{3y-y}{3} =15\\\\\frac{2y}{3} =15\\\\2y = 3(15)\\\\2y = 45\\\\y = \frac{45}{2} \\\\y = 22.5 \ miles[/tex]

Therefore, the distance of Jack's father's work from home is 22.5 miles.

The required distance of Jack's father's work from home is y = 22.5miles.

Given that,

Jacks father drives to work in 30 minutes while driving at his usual speed.

When traffic is bad, he drives 30 miles per hour slower and the trip takes one hour longer.

We have to determine,

How far is Jack's father's work from home.

According to the question,

Let, the usual speed = v

And the distance of Jack's father's work from home = y

Jacks father at usual speed taking time, t = 30 minutes = 0.5 hour,

Jacks father speed when traffic is bad, = 30 mph slower.

The formula for speed is defined as = distance ÷ time.

Therefore,

Jacks father drives to work in 30 minutes while driving at his usual speed.

[tex]Speed = \dfrac{distance}{time}\\\\v = \dfrac{y}{0.5}[/tex]

Then,

When traffic is bad, he drives 30 miles per hour slower and the trip takes one hour longer.

[tex]Speed = \dfrac{distance}{time}\\\\v - 30mph = \dfrac{y}{1+0.5}\\\\v = \dfrac{y}{1+0.5} + 30[/tex]

Substitute the value of v from equation 1 to equation 2,

[tex]v = \dfrac{y}{1+0.5} + 30\\\\\dfrac{y}{0.5} = \dfrac{y}{1.5} + 30\\\\\dfrac{y}{0.5} = \dfrac{y +30(1.5)}{1.5}\\\\y (1.5) = 0.5(y +45)\\\\1.5y = 0.5y + 22.5 \\\\1.5y - 0.5y = 22.5\\\\1y = 22.5\\\\y = 22.5 \ miles[/tex]

Hence, The required distance of Jack's father's work from home is y = 22.5miles.

Answer:

B

x = 22

Step-by-step explanation:

2x + 8 + 3x + 5 = 123    (external angle in a triangle = the two opposite angles)

5x = 123 - 13

5x = 110

x = 22

Answer: B

Step-by-step explanation:

By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.

(2x+8)+(3x+5)=123       [combine like terms]

5x+13=123                     [subtract both sides by 13]

5x=110                           [divide both sides by 5]

x=22

Now, we know that the answer is B.

Answer:9200

Step-by-step explanation: .09 * 2000 = 180 * 40 = 7200 + 2000 = 9200

Balance amount in Jermaine account after 40 years is equals to $9200.

" Simple interest is the process of calculating amount of interest  given on the principal amount at the rate of interest over period of time."

Formula used

S.I. = = (P × R × T) / 100

S.I.= Simple Interest

P = Principal amount

R = Rate of interest

T = Time

Total amount = P + S.I.

According to the question,

Given

P = $2000

R = 9%

T = 40 years

Substitute the given values in the formula we have,

Simple Interest = (2000 × 9 × 40) / 100

                         = $7200

Total balance amount after 40 years = $2000 + $ 7200

                                                              = $9200

Hence, balance amount after 40 years is equals to $9200.

Answer:

57.3°

Step-by-step explanation:

A 25 feet ladder leans against a building.

The ladder's base is 13.5 feet from the building.

The ladder, the wall of the building and the ground form a right-angled triangle of:

Hypotenuse = 25 feet

Base = 13.5 feet

We are to find the angle of elevation which the ladder makes with the ground (or rather the angle created by hypotenuse and base)

Let's say the angle = X°

According to a trigonometric equation;

cos X° = adjacent side ÷ hypotenuse = [tex]\frac{13.5}{25}[/tex] = 0.54

[tex]cos ^{-1} X[/tex] = 57.5=3° (Answer rounded up to nearest one decimal place).

∴ The angle of elevation = 57.3°

Step-by-step explanation:

Given that:

Brittany's Zscore = 1.8

Mean score (m) = 75

Standard deviation (s) = 10

Brittany's score (x) =?

Using the Zscore formula :

Zscore = (x - m) / s

1.8 = (x - 75) / 10

18 = x - 75

18 + 75 = x

93 = x

Hence, Brittany's score is 93

Answer: A

Step-by-step explanation:

Answer A:

Angle H is congruent to angle H. because BC and GI are parrellel, and Angles IGB and CBH are corresponding angles. Triangles HBC and HGI are similar

Yes, the triangles are Similar by SAS similarity criteria the triangles are similar.

Similar triangles have proportional sides and equal corresponding angles. This similarity can be expressed using the symbol "∼".

We have two Triangles named HBC and HGI

As, per the figure CB || IG

We know, A midsegment is parallel to one side of a triangle and divides the other two sides into congruent halves.

Then, HB / BG = HC / HI

Now, add 1 to both side we get

HB / BG  + 1 = HC / HI + 1

(HB + BG) / BG = (HC + HI) / HI

BG / BG = CI / HI

Now, In Triangles HBC and HGI

BG / BG = CI / HI

<H is Common.

Thus, by SAS similarity criteria the triangles are similar.
