Answer:

A = 189.25

Step-by-step explanation:

A = πr²

15 x 10 = 150

5 x 5 x 3.14 = 78.5

78/2 = 39.25

You divide by 2 because it's half of a circle.

150 + 39.25 = 189.25

HELP!! I have been stuck on these questions forever! Im having to multiply or devide in scientific notation. Im having to find the sum or difference. I will mark brainiest.

Answers

these are extremely easy, let me tell you how to do them. You always have to do the question in the parentheses first, so for number 17 it would be 7 times the 10 power 7. When I say power, it’s the little number at the top of the whole number. You have to do 10 times 10 times 10 times 10 times 10 times 10 times 10. Then you get 10 million (10,000,000) now you do 10 million times 5, which is 5 million. So number 17 is 5 million. Now you can do the rest of them the same. When you have decimals, make sure to line them up. Good luck! Feel free to ask me any questions.

please answer this question i will give you brainliest!!!!

Answers

Answer:

your answer will be 25 .....ok

Answer:

x = 25

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 3 when x = 15

3 = 15k ( divide both sides by 15 )

[tex]\frac{3}{15}[/tex] = k, that is k = [tex]\frac{1}{5}[/tex]

y = [tex]\frac{1}{5}[/tex] x ← equation of variation

When y = 5 , then

5 = [tex]\frac{1}{5}[/tex]x ( multiply both sides by 5 to clear the fraction )

25 = x

Solve the system using elimination.
y=-x-3
y=x2-15

Answers

Answer:

X=4, y=-7

Step-by-step explanation:

To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2

2(y)=2(-x-3)

2y=-2x-6

——————

add above equation 2y=-2x-6

to second equation    Y=2x-15

add together.           3y=-21

                                   Y=-7

—————————————-

solve for x by substituting y value (7) into either equation

y=-x-3

-7=-x-3

-4=-x

john is twice as old as his son. his son is 5 years older than his sister . in five years to come John will be 3 times as old as his daughter. how old is his son now?​

Answers

Answer:

5

Step-by-step explanation:

Terrible wording on the question as the "father" is 15 the "son" is 10 and the sister is 0 or just born

J = john

S = son

X = sister

J = 2s

S = 5 + X

3(x+5) = J + 5

J = 2(5+x) = 2x + 10

3x+15 = 2x +10 + 5

x = 0

Answers

Answer: Number 1 is c=89 ft

Number 2 is b=3 cm

Step-by-step explanation: a²+b²=c²

For number 1, 39 ft is a and 80 ft is b so

39²+80²=c² so 39² is 39x39=1521 and 80² is 80x80=6400 so 6400+1521=7921

7921=c² and the square root of 7921 is 89 so c=89 ft

For number 2, a=1.6 cm and c=3.4 cm so 3.4²-1.6²=b²

3.4² so 3.4x3.4 which is 11.56

1.6² so 1.6x1.6 which is 2.56

11.56-2.56=c² and 11.56-2.56=9

Square root of 9 is 3 so b=3

So number 2 answer is b=3 cm

Cade and Tyce both tried to find the missing side of the right triangle.


A right triangle is shown. The legs are labeled 6 and 9. A right angle is labeled in between them.

Cade's Work Tyce's Work

a2 + b2 = c2 a2 + b2 = c2

62 + b2 = 92 62 + 92 = c2

36 + b2 = 81 36 + 81 = c2

b2 = 45 117 = c2

Square root b squared equals square root 45. Square root 117 equals c squared.

b ≈ 6.71 10.82 ≈ c

Is either of them correct? Explain your reasoning.

Answers

Answer: a2 + b2 = c2 a2 + b2 = c2 is correct

Step-by-step explanation:

reason being:

if a2 and b2 are in the equation that would make c2 a2 rational and when the number is rational thats automatically easy to know the area and square root and thats the key! the questions states the spuare root and area which makes it all easy to know that the correct one is a2 + b2 = c2 a2 + b2 = c2.

(Hopes this helps)

Tyce is correct because you are finding the hyphenous and not the missing side.

Find S7of the sum of the geometric series.a1=−4374,a7=−6,r=1/3
Group of answer choices

A. −6568

B. −6583

C. −6563

D. −6534

Answers

Answer:

The sum of the first 7 terms in the geometric sequence is -6558

Step-by-step explanation:

s7 refers to the sum of the first 7 terms of the geometric sequence

To calculate the sum of terms, we use the sum of terms formula

We have this generally given as;

Sn = a(1-r^n)/(1-r)

a refers to the first term, given as a1 which is -4374

r is the common ratio which is 1/3

n is the number of terms, which is 7

substituting these values;

s7 = -4374(1-(1/3)^7)/(1-1/3)

s7 = -4374(1-(1/3)^7)/2/3

s7 = (3 * -4374)/2 * (1- (1/3)^7

s7 = -6561 * (1-1/2187)

s7 = -6561 * (2187-1)/2187

= -6561 * 2186/2187

= -6558
