10Find The Area Of The Semicircle.Either Enter An Exact Answer Terms Of Ar Or Use 3.14 For At And Enter

Answers

Answer 1

Answer:   39.25

========================================

Work Shown:

d = diameter = 10

r = radius = d/2 = 10/2 = 5

A = area of a full circle

A = pi*r^2 = 3.14*5^2 = 78.5

Cut this in half to get the area of a semicircle (aka half circle)

(78.5)/2 = 39.25

This result is approximate.

Solve for x.

−5x−8>22

Enter your answer in the boxes to correctly state the solution.

Answers

Answer:

x < -6

Step-by-step explanation:

-5x - 8 > 22

Add 8 to both sides:  -5x > 30

Divide both sides by 5:  -x > 6

Divide both sides by -1 (reverse sign):  x < -6

Answer:

x < -6

Step-by-step explanation:

First we want to move all terms not containing x to the right side

-5x > 22 + 8

-5x > 30

Then we want to divide

-5x/5 < 30/-5

30/-5

x < - 6

solve for x,y, and 15

Answers

Answer:

27

Step-by-step explanation:

x + y = 15 (gallons)      (1)

0.25*x + 0.10 * y = 0.15 * 15   (2)

Multiply 100 on (2):

25x + 10y = 15

Divede by 5

5x + 2y = 3     (3)

From (1) y = 15 - x

so 5x + 10*(15 - x) = 15

5x + 150 - 10x = 15

-5x = 15 - 150 = -135

x = 135/5 = 27 (gallons)

First we need the height of the cone

so we divide the cone to two equal parts that means the adjacent 5 inches will be divided into two to give 2.5

then we use get a triangle from the cone and that's how we find our height using pythagoras theorem

hypotenuse Square = opposite Square + adjacent Square

7^2 = x^2 + 2.5^2

therefore our height is 6.53

now to get the surface area of the cone we use the formula

Given in the question, [tex]\frac{4}{5} =\frac{y}{7} \\[/tex], using the concept of direct proportion, y = 5.6

Direct proportion is the concept of proportionality where one variable increases/decreases when another increases/decreases and vice versa. The rate of increase/decrease can be measured through the constant ratio. The two quantities which are directly proportional are related by a Direct Proportion symbol '∝'.

Given in the question,

[tex]\frac{4}{5} =\frac{y}{7} \\[/tex]

multiplying 7 on both sides,

[tex]\frac{4}{5}*7 = \frac{y}{7} *7\\ \\ \frac{28}{5} = y \\\\y = 5.6[/tex]

13(2-x)=2*x

then we multiply

26-13x=2x

we then collect like terms

Two or more expressions with an Equal sign is called as Equation. Value of x is 26/15 for equation 13/x=2/(2-x)

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is

13/x=2/(2-x)

Apply cross multiplication

13(2-x)=2x

Apply Distributive property on LHS side

13(2)-13x=2x

26-13x=2x

Add 13x on both sides

26-13x+13x=2x+13x

26=15x

x=26/15

Hence value of x is 26/15 for equation 13/x=2/(2-x)

1. In a concert hall, the number of seats in each row increases as you move farther from the stage. There are
the first row, 38 seats in the second row, and 45 seats in the third row.
a) If this pattern continues, determine what type of sequence this represents. Then write a function rule in simplified
form that can be used to find the number of seats in the nth row. Be sure to use the correct notation you have
learned this unit. Show ALL work.
b) Use the rule to determine which row has 290 seats. Show ALL work.

Answers

According to the situation described, we have that:

a) The arithmetic sequence that gives the number of seats in the nth row is given by:

[tex]a_n = 24 + 7n[/tex]

b) The 38th row has 290 seats.

What is an arithmetic sequence?

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

Item a:

The first row has 31 seats, the second has 38, the third has 45 and so on, hence:

It is an arithmetic sequence.The common difference is d = 7.The first term is [tex]a_1 = 31[/tex].

Then, the rule is:

[tex]a_n = a_1 + (n - 1)d[/tex]

[tex]a_n = 31 + 7(n - 1)[/tex]

[tex]a_n = 24 + 7n[/tex]

Item b:

This is the nth row, for which [tex]a_n = 290[/tex], hence:

[tex]a_n = 24 + 7n[/tex]

[tex]290 = 24 + 7n[/tex]

[tex]7n = 266[/tex]

[tex]n = \frac{266}{7}[/tex]

[tex]n = 38[/tex]

The 38th row has 290 seats.

See the attached picture for the answer:

Answer:

The maximum angle they can use the ladder is 65.38º

Step-by-step explanation:

Sine law allows sinA/a = sin B/b = sin C/c

Reference the drawing attached

sin 90/110m = sinB/100m

1/110m = sinB/100

multiply both sides by 100

100/110 = sinB

divide each side by 10

10/11 = sinB

find inverse sin of both sides

sin^-1(10/11) = B

Kiara sets up a passcode on her smart phone, which allows only eight-digit codes. A spy sneaks a look at Kiara's smart phone and sees her fingerprints on the screen over
eight numbers. What is the probability the spy is able to unlock the smart phone on his first try? Express your answer as a fraction in lowest terms or a decimal rounded
to the nearest millionth.

Answers

Probabilities are used to determine the chances of events

The probability the spy is able to unlock the smart phone on his first try is 0.00000001

How to determine the probability

The length of the password is given as:

L = 8

Each of the digit in the password can take any of digits 0 - 9 (i.e. 10 digits)

So, the number of possible password is:

[tex]n = 10^8[/tex]

The probability that the spy unlocks the phone is:

[tex]p =\frac 1n[/tex]

So, we have:

[tex]p = \frac 1{10^8}[/tex]

Simplify

[tex]p = 0.00000001[/tex]

Hence, the probability the spy is able to unlock the smart phone on his first try is 0.00000001

To visit the manila Zoo, 11 adults and 5 Children have to pay 270 whereas 14 adults and 9 children have to pay 370? Find the total amount a family of 2 adults and 3 children has to pay to visit the zoo.

Answers

Step-by-step explanation:

let adults be x and childrens be y

a/q

11x + 5y = 270

14x + 9y = 370

→ x = -5/11y + 270/11 ; 14x + 9y = 370

→ 14(-5/11y + 270/11) + 9y = 370

→ y = 10

→ x = -5/11 × 10 + 270/11

→ x = -50/11 + 270/11

→ x = 20

therefore, we got

x = 20, y = 10

each adult have to pay 20 and each children have to pay 10

so,

2 × 20 = 40

3 × 10 = 30

40 + 30 = 70

for a family of 2 adults and 3 children they have to pay 70.
