Answer:

Option C. 15 cm

Step-by-step explanation:

The correct question is

A triangle has two sides that measure 8.7 cm and 12.3 cm. Which could be the measure of the third side?

A. 2.6 cm

B. 3.6 cm

C. 15 cm

D. 21 cm

we know that

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Analyze two cases

Let

x ----> the length of the third side

First case

x+8.7 > 12.3

x>12.3-8.7

x> 3.6 cm

Second case

12.3+8.7 > x

21 > x

Rewrite

x < 21 cm

True or false? Three out of two people have trouble with fractions.<br> Please explain
svetlana [45]

Answer:

False

Step-by-step explanation:

3 out of 2 can be represented as 3/2 which simplified is 1.5, This statement is saying that out of 1 person, 1.5 of them have trouble with fractions which isn't possible because 2/2 is the whole amount, so anything above 2/2 is simply not possible <u>in this scenario</u>

Write a recrusive rule for the exponential function<br>f(x)=0.25(2/3)^x​
krok68 [10]

Answer:

f(0) = 0.25 = 1/4

f(x) = f(x-1) × 2/3

Step-by-step explanation:

a0 = 0.25×(2/3)⁰ = 0.25×1 = 0.25 = 1/4

a1 = 0.25×(2/3)¹ = 0.25×(2/3) = 1/4 × 2/3 = 2/12 = 1/6 =

= a0 × 2/3

a2 = 0.25×(2/3)² = 0.25×(4/9) = 1/4 × 4/9 = 4/36 = 1/9 =

= a1 × 2/3

=>

an = an-1 × 2/3, n >= 1

but what about negative x ?

is a0 = a-1 × 2/3 ?

a - 1 = 0.25 \times  {(2 \div 3)}^{ - 1}

so, yes, a0 = a-1 × (2/3)

and a-1 = a-2 × (2/3)

Solve the equation below for x:<br><br><br> 0.25(x - 13) = 7
VikaD [51]

Answer:

x=41

Step-by-step explanation:

0.25(x-13)=7

We move all terms to the left:

0.25(x-13)-(7)=0

We multiply parentheses

0.25x-3.25-7=0

We add all the numbers together, and all the variables

0.25x-10.25=0

We move all terms containing x to the left, all other terms to the right

0.25x=10.25

x=10.25/0.25

x=41
