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:

81.57 cm

Step-by-step explanation:

Given that :

Scale :

3cm : 100km

This means ; 3cm on the map represents an actual length of 100km

Actual length of shoreline = 2719 km

The length of the shoreline on the map will be :

(2719 km / 100 km) * 3cm

27.19 * 3cm

= 81.57 cm

Answer:

81.57 cm

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:

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: 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

Step-by-step explanation:

Answer:

80

Step-by-step explanation:

Freddie is one meter shorter than his father

His father is 180 centimeters tall

So freddie is 80 centimetres

Freddie is mother÷2

So 80=M÷2

Mother is 190 centimeters

The number of centimeters when Freddie’s mother should be tall is considered to be 90.

Since

Freddie is half as tall as his mother.

Freddie is one metre shorter than his father.

Freddie’s father is 180 centimetres tall.

So

the Freddie is mother is

= 180 / 2

= 90

hence, The number of centimeters when Freddie’s mother should be tall is considered to be 90.

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

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
