Jordan spent 22% of his time doing math homework. If hw spent 11 minutes on his math homework. How many minutes did he spend on

devlian [24]

Answer:

The total minutes he spend on his homework are 50 minutes.

Step-by-step explanation:

It is given that Jordan spent 22% of his time for homework on maths.

It is also given that he spent 11 minutes of time on maths homework.

The above two statements are equal.

Let the total time for homework be "x".

Thus, the equation can be written as,

$(\frac{22}{100})(x) = 11$

$x = (\frac{100}{22})(11) = 50 minutes$

Thus the total minutes he spend on his homework are 50 minutes.

16. Construct 3 equations starting with x = 5.

strojnjashka [21]

TO FIND:  construct 3 equation starting with x=5?

SOLUTION: 

The equation is in the form of variable and constant equating.

Let the equation be x=5.

TO CREATE AN EQUATION,

FIRST WE ADD 5 BOTH SIDe,

x + 5=5+5

=x + 5=10

SECOND WE SUBRACT 5 BOTH SIDE,

x — 5=5—5

=x—5=0

THIRD WE MULTIPLY 5 BOTH SIDE,

5x=5×5

=5x=25

well u got the answer!

An experimental population of fruit flies increases according to the law of exponential growth. There were 60 flies after the 2n

Mice21 [21]

Answer:

There were 10 flies originally

Step-by-step explanation:

Since we have an exponential growth, we will be having a constant percentage of increase and we can set up the increase at any day using the following equation;

V = I(1+r)^d

where V is the number of flies on a particular day

I is the initial number of flies

r is the constant increase in percentage

and d is the number of days.

So we have for the second day;

60 = I(1+r)^2 ••••••(i)

For the fourth day, we have;

360 = I(1+r)^4 ••••••••(ii)

divide equation ii by i; we have;

360/60 = (1+r)^4/(1+r)^2

6 = (1+r)^2

(√6)^2 = (1+r)^2

1 + r = √6

r = √6 - 1

So we can substitute the value of r in any of the equations to get I which is the initial number of flies

Let’s use equation 1

60 = I(1 + r)^2

60 = I(1 + √6 -1)^2

60 = I(√6)^2

60 = 6I

I = 60/6

I = 10 flies

Ede4ka [16]

Answer:

28"

Step-by-step explanation:

the length of the other non-hypotenuse side =

√(53² - 45²) =√(2809-2025) =√784 = 28"
