Answer:

Cat  sleeps 420 hours than Alice  in a month

Step-by-step explanation:

Given:

Number of  hours Alice sleeps per night = 9 hours

Number of  hours Cat sleeps per night = 20 hours

To Find:

How many more hours does a cat sleep in 1 month that Alice

Solution:

Let

The total number of hours for which Alice Sleeps in one month be x

The total number of hours for which Cat sleeps in one month be y

Step 1: Number of hours for which Alice Sleeps in one month

X = number of days in a month  X  Number of hours Alice sleeps per night

X = 30 X 9

X = 180 Hours

Step 2: Number of hours for which Cat Sleeps in one month

y= number of days in a month  X  Number of hours cat sleeps per night

y = 30 X 20

y = 600 Hours

Now ,

=> y – x  

=>600 – 180

=>420 hours

Write the equation in y-intercept form slope 2 passes through point (5,-2)
Alenkinab [10]
<h2>Answer</h2>

The equation is y = 2x - 12

<h2>Explanation</h2>

Equation in slope intercept form is

y = mx + b

Where,

m = slope

b = y-intercept

Putting the value of slope in this equation:

y = 2x + b

From this we can solve the equation for b

b = y - 2x

b = -2 - 2(5)

b = -12

Now, the equation of y-intercept becomes

y = 2x - 12

In 2010, the world's largest pumpkin weighed 1,810 kilograms. An average-sized pumpkin weighs 5,000 grams.
jekas [21]

Answer:

1,805 kg.

Step-by-step explanation:

We have been given that in 2010, the world's largest pumpkin weighed 1,810 kilograms. An average-sized pumpkin weighs 5,000 grams. We are asked to find the how much the world's largest pumpkin weighs than an average pumpkin.

First of all, we will convert the weight of average pumpkin in kilograms by dividing 5,000 by 1000 as 1 kg equals 1,000 gm.

\text{The weight of average pumpkin}=\frac{5000\text{ gm}}{\frac{\text{1000 gm}}{\text{ 1 kg}}}

\text{The weight of average pumpkin}=5000\text{ gm}\times \frac{\text{ 1 kg}}{\text{1000 gm}}

\text{The weight of average pumpkin}=5\text{ kg}

Now, we will subtract the weight of average pumpkin from world's largest pumpkin's weight.

1,810\text{ kilograms}-5\text{ kilograms}=1,805\text{ kilograms}

Therefore, the 2010 world-record pumpkin weighs 1,805 kilograms more than an average-sized pumpkin.

PLS THIS IS MY LAST QUESTION
MrRa [10]

Answer: x = 5.625

Step-by-step explanation:  The triangles are similar; the side lengths of the large triangle are proportional to the lengths of the small triangle. The corresponding parts are proportional.

Use proportion. The total length of side FV is 16.

6:16 = x:15 . or 6/16=x/15

cross multiply 15 × 6 = 90, then divide 90/16

90/16 = x

5.625 = x
