Answer:

A.

Step-by-step explanation:

got it right on test

The provided expression is equivalent to the expression mentioned in option (A), and option (A) is correct.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

[tex]= 5^{9.969}[/tex]

We can write it as:

[tex]= 5^{\dfrac{9969}{1000}}[/tex]

or

[tex]= 5^{\dfrac{9000+900+60+9}{1000}}[/tex]

[tex]= 5^{{9}} \ 5^{\dfrac{9}{10}} \ 5^{\dfrac{6}{100}} \ 5^{\dfrac{9}{1000}}[/tex]

Thus, the provided expression is equivalent to the expression mentioned in option (A), and option (A) is correct.

Answer:

B, C, E

Step-by-step explanation:

Elena’s aunt pays her $1 for each call she makes to let people know about her aunt’s new business. The table shows how much money Diego receives for washing windows for his neighbors.

Select all the statements about the situation that are true.

A. Elena makes more money for making 10 calls than Diego makes for washing 10 windows.

Elena:

$1 = 1 call

$10 = 10 calls

Diego:

27 windows = $30

10 windows = $x

Cross product

27*x = 30*10

27x = 300

x = 300/27

x = $11.11

Statement A not true

B. Diego makes more money for washing each window than Elena makes for making each call.

Diego:

10 windows = $11.11

Each window = $11.11/10

= $1.11

Statement B is true

C. Elena makes the same amount of money for 20 calls as Diego makes for 18 windows

Elena:

20 calls = $20

Diego:

18 windows = 18 × $1.11

= $19.98

Approximately $20 to the nearest whole dollar

Statement C is true

D. Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls.

Diego

35 × $1.11 = $38.85

Approximately $39

Elena:

40 calls = $40

Statement D is not true

E. The equation y = x, where y is the number of dollars and x is the number of calls, represents Elena’s situation.

Statement E is true

Answer:

68°

Step-by-step explanation:

since the angle given is a complementary angle, we know that the sum of it must equal 180°

let the unknown angle below j be x so,

[tex]25+43+x=180\\x=180-25-43\\x=112[/tex]

now since the angle on the left of j is equal to x we can say

[tex]x+j=180\\j=180-x\\j=180-112\\j=68[/tex]

Answer: 3m/s

Step-by-step explanation:

the formula for speed is distance divided by time, the question tells us the time is referring to the first 30 seconds, so just divide the distance by time (the answers you’d get are 3, 3, 1) so 3 m/s is closest to the average speed

The average speed of the bicyclist during 30 seconds of motion is mathematically given as

v'=3m/s

Question Parameter(s):

During 30 seconds of motion

Generally, the equation for the  speed is mathematically given as

v=d/t

Therefore

v'=(30/10+60/20+30/30)3

v'=3m/s

In conclusion, Average speed

v'=3m/s

Answer:

7

Step-by-step explanation:

We can simplify this because 6x - 3x is equal to 3x, so we get that the expression is 3x - y + 5. Next, we can plug in our values. 3 * 4 - 10 + 5 is equal to 12 - 10 + 5, which is 2 + 5, which is 7.

The value of the expression 6x - 3x + 5 - y at x = 4 and y = 10 is 7.

Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.

Given, An expression 6x - 3x + 5 - y.

Now, The value of the expression at x = 4 and y = 10 can be obtained by replacing the numerical values of x and y.

Therefore, 6x - 3x + 5 - y at x = 4 and y = 10 is,

6(4) - 3(4) + 5 - 10.

= 24 - 12 + 5 - 10.

= 12 - 5.

= 7.

Answer:

  4.3 in

Step-by-step explanation:

The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...

  f² = d² + e² -2de·cos(F)

  f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671

  f ≈ √18.0671 ≈ 4.2505

The length of f is about 4.3 inches.

Step-by-step explanation:

A pentagon's angle all add up to 540

[tex]460+x=540[/tex]

[tex]x=80[/tex]

Answer:A 80

Step-by-step explanation:

So a square is all 90° angles so take 90 from 140 and get 50 and 50+50=100 and a triangles thing adds up to 180 so 180-100=80 (I’m not good at explaining sorry)

Answer:

the total weights in tons is 18

Step-by-step explanation:

The computation of the total weights in tons is shown below:

The weight of 8 cars would be

= 4,500 pounds × 8 cars

= 36,000 pounds

Now as we know that 1 ton = 2,000 pounds

So for 8 trucks it would be

= 36,000 pounds ÷ 2,000 pounds

= 18 tons

Hence, the total weights in tons is 18
