Answer:

The median is 15cm.

Step-by-step explanation:

Given that the The length of the congruent sides of an isosceles triangle is 17cm . the base of the triangle is 16 cm . And we need to find the median .

We know that in a isosceles triangle

This means that the base will be divided into two equal parts For Figure refer to attachment .

⇒ BM² + AM² = AB²

⇒ (17cm)² = (8cm)² + AM²

⇒ 289 cm² = 64cm² + AM²

⇒ AM² = 289 cm² - 64 cm²

⇒ AM² = 225 cm²

⇒ AM = √225 cm²

⇒ AM = 15 cm .

Answer: Adults = 58

Children = 42

Step-by-step explanation:

Let adults be denoted as a

Let Children be denoted as c

a + c = 100 ...... i

10a + 5c = 710 ...... ii

Multiply I by 5

Multiply ii by 1

5a + 5c = 500 ...... iii

10a + 5c = 710 ...... iv

Subtract iii from iv

5a = 210

a = 210/5

a = 42

Since a + c = 100

c = 100 - 42 = 58.

Adults = 58

Children = 42

Answer:

The probability is zero

Step-by-step explanation:

Probability

There are 3 white counters and 2 black counters in a bag. One of them is chosen at random.

It's required to calculate the probability that a green counter has been chosen.

The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.

The equation to calculate the probability is:

[tex]P=\frac{f}{n}[/tex]

Where f is the number of favorable cases and n is the total cases.

Since there are no green counters in the bag, it's impossible to choose a green counter, thus f=0 out of n=5 total cases:

[tex]P=\frac{0}{5}[/tex]

P = 0

We have put the cross in the mark 0 on the probability scale below

Answer:

2, 8, 14, 20, 26

Step-by-step explanation:

At n=0

2 x 0 +2=2

At n=1

6 x 1 +2=8

At n=2

6 x 2 +2 = 14

At n=3

6 x 3 +2 = 20

At n=4

6 x 4 +2 = 26

Answer:

Answer:

r = (C - By) / A

Step-by-step explanation:

Ar + By = C

_________

-By -By

[Subtract both sides by By (Subtraction poe)]

Ar = C - By

________

(Ar) = (C - By)

[Use parenthesis to group both terms (Associative property of equality)]

________

÷A ÷A

[Divide both sides by A to isolate r so it can be solved (Division poe)]

________

r = (C - By) / A

Answer:

y=-1/3x + 17/3

Step-by-step explanation:

Just follow the slope-intercept form formula-

Formula: y=mx+b

Key:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Answer:

x = 2.52

Step-by-step explanation:

30.16 = 17.56 + 5x

30.16 - 17.56 = 5x

12.6 = 5x

12.6/5 = 5x/5

2.52 = x

Answer:

26/35

Step-by-step explanation:

6/35+4/7

you need to make the second fraction have the same denominator

to do this, you need to do 7 times 5 to make 35

times the numerator by the same

this would mean:

6/35+20/35=26/35

Answer:

Simple Interest = $315

Step-by-step explanation:

The formula for Simple Interest

I = P× R × T

I=interest, p=principal, r=rate, t=time

P = $1750

R = 12% = 0.12

T = 1.5 years

I = $1750 × 0.12 × 1.5

I = $315

-3x+6<-6

-3x<-12

Answer:

x+y-3+6

or

x+y+3

Given:

The function is [tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex].

To find:

The function [tex]f^{-1}(x)[/tex].

Solution:

We have,

[tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex]

Substitute f(x)=y.

[tex]y=3(x+7)^{\frac{1}{4}}[/tex]

Interchange x and y.

[tex]x=3(y+7)^{\frac{1}{4}}[/tex]

Divide both sides by 3.

[tex]\dfrac{x}{3}=(y+7)^{\frac{1}{4}}[/tex]

Taking power 4 on both sides.

[tex]\left(\dfrac{x}{3}\right)^4=y+7[/tex]

Subtract 7 from both sides.

[tex]\left(\dfrac{x}{3}\right)^4-7=y[/tex]

[tex]y=\left(\dfrac{x}{3}\right)^4-7[/tex]

Substitute [tex]y=f^{-1}(x)[/tex].

[tex]f^{-1}(x)=\left(\dfrac{x}{3}\right)^4-7[/tex]

Therefore, the correct option is C.

Hey there!

Yes, it does. It rounds to 1.4.

1.414213562 rounded to the nearest tenth is 1.4, since the next number is less than 5, the 4 stays the same. If the next number was a 5 or greater, it would be 1.5, instead of 1.4.

Hope this helps! Good luck and have  great day!
