What is the solution to the equation below? (round your answer to two decimal places.)ln(x - 5) = 0.4?

1 answer:

3 0

First, you add 5 to the answer given, then you would end up with the value of X, x= 5.4 (the answer to two decimal places is 5.40)

This is basically doing the opposite of what the number's sign is. for example:

x+7=14, you would subtract 7 from the answer (14) and you would find the variable (x) that would mean that x=7.

This also applies for more complex equations like:

y x 12= 24

You can find the answer to this by dividing 24 (the answer given) by 12, which gives you 2. That would mean y=2

You can also check yourself with these equations by replacing the answer you got for the variable (the letter in the equation)

2 (y) x 12 = 24 y=2
5.4 (x) - 5 =0.4 x=5

Answer:

▶ (c) 10.3 cm

Step-by-step explanation:

$\space$

A = b × h

=> 154.5 = b × 15

=> b = $\sf{\frac{154.5}{15} }$

=> 10.3 cm

If a || b, m∠2 = 63°, and m∠9 = 105°, find the measure of each missing angle.

Ne4ueva [31]

Given that a || b, m∠2 = 63° and m∠9 = 105°.

Now, all the angles are as follows:

m∠5= m∠2 = 63° [vertically opposite angle]

m∠7= m∠9=105° [vertically opposite angle]

m∠8= 180°-m∠9=180°-105°=75° [Supplementry angles, m∠8+m∠9=180°]

m∠10= m∠8= 180° [vertically opposite angle]

m∠6= m∠8=75° [ Alternate angles]

m∠3= m∠6=75° [vertically opposite angle]

m∠1= 180°-(m∠2+m∠3)=180°-(63°+75°)=42° [as m∠1+m∠2+m∠3=180°]

m∠4= m∠1=42° [vertically opposite angle]

m∠11=m∠4=42° [ Alternate angles]

m∠13= m∠11=42° [vertically opposite angle]

m∠12= 180°-m∠11=180°-42°=138° [as m∠8+m∠9=180°]

m∠14 = m∠12=138° [vertically opposite angle]

Add 6 and 8. Then, multiply by 2.

Delvig [45]

Answer:

C. 2 x (6 + 8)

Step-by-step explanation:

If you are trying to add before you multiply, you have to put a parantheses. This way, you would add 6 + 8 first, then multiply it by 2.

A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Ever

hichkok12 [17]

Answer:

$\dfrac{17}{72}$

Step-by-step explanation:

From the given information:

Total number of students, $n(U)=72$

The choices were: Chess(C), Swimming(S), and Football(F).

Everyone liked at least one sport except 7 kids, $n( C \cup F \cup S)'=7$

Chess is not an active sport; and

10 children liked Chess only, $n( C \cap F' \cap S')=10$

The probability that a randomly-chosen child from this group does not like active kinds of sport is the Probability that a student plays chess only or like no kind of sport at all.

$P( C \cup F \cup S)'+P(C \cap F' \cap S')=\dfrac{n( C \cup F \cup S)'+n(C \cap F' \cap S')}{n(U)} \\=\dfrac{10+7}{72} \\=\dfrac{17}{72}$
