Step-by-step explanation:

Hey there !!!!!

to, see how much did the man travel in total. you just add all of the distances that the man traveled.

he traveled:

13.2  by tairn

45.07 by bicycle

17.2 by car

if you add all of them up :

45.07 + 13.2 = 58.27

58.27 + 17.2 = 75.47

have a wonderful day

Answer:

75.47

Step-by-step explanation:

because the sum of 13.2,45.07 and 17.2 is 75.47

Step-by-step explanation:

9 directly precede 2, 4 times, in the sequence, 12909296292629.

An ordered list of things is a sequence (or events). Similar to a set, it has members (also called elements, or terms). The length of the sequence is the number of ordered items (potentially infinite).

In the given sequence,

12909296292629,

there are 4 such 9's that are preceded by 2 immediately.

That means, for the clear representation,

1-29-09-29-6-29-26-29

Therefore, there are 4 such 9's that are preceded by 2.

Answer:

Assuming that the notation there is meant as:

[tex](3c)^{-2}[/tex]

then the answer would be 1/(9c²)

If the -2 is indeed just subtraction and not an exponent, then it is simply 3c - 2

The expression equivalent to 1/9c².

An expression is a set of terms combined using the operations +, – , x or for example 4 x − 3 or x 2 – x y + 17 .

An equation states that two expressions are equal in value,

for example 4 b − 2 = 6 .

Given:

[tex](3c)^{-2}[/tex]

To make the power positive, just do the reciprocal

=1/ (3c)²

=1/9c²

Hence, the expression

[tex](3c)^{-2}[/tex] is equivalent to 1/9c².

Answer:

The answer is t=8

Step-by-step explanation:

simplify both sides or the equation, then isolate the variables

Answer:

t = 8

Step-by-step explanation:

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 6 to both sides of the equation:

1/4t + (-6) = -4

1/4t - 6 = -4

1/4t - 6 (+6) = -4 (+6)

1/4t = -4 + 6

1/4t = 2

Next, multiply 4 to both sides of the equation to isolate the variable, t:

4 * (1/4)t = (2) * 4

t = 2 * 4

t = 8

t = 8 is your answer.

Answer:

x=7.5

Step-by-step explanation:

Since AD II EH, ∠CBD=∠BFH (alternate angles)

2x+60=10x

8x=60

x=7.5

Answer:

x = 7.5

each angle measures 75°

Step-by-step explanation:

the two angles are corresponding, meaning they are equal

10x = 2x + 60

8x = 60

x = 7.5

Answer:

[tex]\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}[/tex]

Step-by-step explanation:

Given

See attachment

To answer this question, we start by equating the denominators of each option to 0; then, solve for x

(a):

[tex]\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}[/tex]

This gives

[tex]\frac{7x}{x^2 - 10x + 21} * \frac{7}{x + 7}[/tex]

Set the denominator to 0

[tex](x^2 - 10x + 21)(x + 7) = 0[/tex]

Solve for x

[tex](x^2 - 7x - 3x + 21)(x + 7) = 0[/tex]

Factorize:

[tex](x(x - 7) - 3(x - 7))(x + 7) = 0[/tex]

[tex](x - 7)(x - 3)(x + 7) = 0[/tex]

This implies that:

[tex]x = 7\ or\ x = 3\ or\ x = -7[/tex]

From above, one of the values of x is 7.

This implies that x = 7 is an excluded value for this quotient.

Other options do not need to be checked, since there is only one answer.

Step-by-step explanation:

Find the HCF of 64 , 72

64  = 2 * 2 * 2 * 2 * 2 *2 = 2^6

72 = 2 * 2 * 2 * 3 * 3

HCF = 2*2*2 = 8

64 : 72 = [tex]\frac{64}{72}[/tex]

            = 64 ÷ 8
