Answer:

x = 44

Step-by-step explanation:

3x - 5 is complementary to y° so their sum is 180°

The angle with measure 127° is also complementary with y°

127 + y = 180

y = 53°

53 + 3x - 5 = 180

3x + 48 = 180

3x = 132

x = 44

Kiran read for x minutes, and Andre read for 58 more than that. Write an equation that relates the number of minutes Kiran read
bogdanovich [222]

Answer:

0.017y=0.017x+0.97

Step-by-step explanation:

Let us assume that,

number of minutes read by Kiran is = x minutes.

number of minutes read by Andre is = y minutes.

Andre read for 58 minute more than that of Kiran.

Converting minute to hour we get,

x\text{ minutes}=\dfrac{x}{60}=0.017x\text{ hour}

y\text{ minutes}=\dfrac{y}{60}=0.017y\text{ hour}

58\text{ minutes}=\dfrac{58}{60}=0.97\text{ hour}

So the relationship between x and y will be,

0.017y=0.017x+0.97

Answer:

The exponential Function is 20+12h=200.

Farmer will have 200 sheep after <u>15 years</u>.

Step-by-step explanation:

Given:

Number of sheep bought = 20

Annual Rate of increase in sheep = 60%

We need to find that after how many years the farmer will have 200 sheep.

Let the number of years be 'h'

First we will find the Number of sheep increase in 1 year.

Number of sheep increase in 1 year is equal to Annual Rate of increase in sheep multiplied by Number of sheep bought and then divide by 100.

framing in equation form we get;

Number of sheep increase in 1 year = \frac{60}{100}\times20 = 12

Now we know that the number of years farmer will have 200 sheep can be calculated by Number of sheep bought plus Number of sheep increase in 1 year multiplied by number of years  is equal to 200.

Framing in equation form we get;

20+12h=200

The exponential Function is 20+12h=200.

Subtracting both side by 20 using subtraction property we get;

20+12h-20=200-20\\\\12h=180

Now Dividing both side by 12 using Division property we get;

\frac{12h}{12} = \frac{180}{12}\\\\h =15

Hence Farmer will have 200 sheep after <u>15 years</u>.
