Answer:

200,000

Step-by-step explanation:

WE MUST USE THE PEMDAS RULE / ORDER OF OPERATION:

Parenthases

Exponent

Multiply

Divide

Add

Subtract

((5 x (10 to the 4th)) / 25) TIMES (10 to the second)

FIRST WE WORK ON THE FIRST PARENTHESIS:

10 to the 4th (10 x 10 x 10 x 10) = 10, 000

MULTIPLE 10, 000 by 5 (10,000 x 5 = 50, 000)

Then DIVIDE by 25 (50, 000 ÷ 25 is 2,000)

WE HAVE 2000 for parenthesis 1.

Now the second one:

10 to the 2nd in 10 x 10....thats equal to 100

2000 x 100 is 200,000! I HOPE YOU UNDERSTAND

As a fraction it would be 10 to the 6th power over 5 but the alternative would be 200000

A number is equal to twice a smaller number plus 3. Yhe same number is equal to twice the sum of smaller number and 1. How many
allsm [11]

Answer:

There is no solution to the problem

Step-by-step explanation:

In order to find the solutions to the problem you can write the situation in an algebraic form.

You have that a number is equal to twice a smaller number plus 3. This can be written as follow:

x=2y+3      (1)

where x is the number and y is the smaller number

Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:

x=2(y+1)     (2)

To find the solution you equal the equation (1) with (2), and you solve for y:

2y+3=2y+1

3=1

You obtain an inconsistency, hence, the situation of the problem does not have solution

Marta hopes to have a test average of at least 90 by the end of the marking period. Her grades on the first four tests have been
Virty [35]

Answer:

 Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.

Explanation:

 Marks received by Marta in four tests =  86, 84, 97 and 89

 Let mark received in fifth test be x

 We have average of five test is more than or equal to 90

 So we have

    \frac{86+84+97+89+x}{5} \geq 90\\ \\ 86+84+97+89+x\geq 450\\ \\ x\geq 94

 So Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.

tresset_1 [31]
47/8 is an improper fraction so we need to divide 47 by 8 to get an mixed number.
8 go into 47, 5 times  because 5*8 equals 40. 
47-40 is 7 that is the left over.
5 7/8 is your mixed number.

A line with a slope of 4 passes through the point (2, 1 ). What is the equation of this line?​
castortr0y [4]

Answer:Put this in y= mx +b form

we have the slope(4) as well as a set of points for x and y so we have everything we need to solve for b

1= 4(2) + b

1 =8+b   B=-7

so equation is y = 4x -7
