a 12-pounded bag of dog food costs $12.36. a 15-pounded bag of cat food cost $15.30. which is a better deal???

7 0

Each pound of the dog food costs $1.03 .
Each pound of the cat food costs $1.02 .

If you own a dog, then the dog food is the better deal.

If you own a cat, then the cat food is the better deal.

You would not want to feed your pet on food formulated for
a different species of animal, just to save a few pennies.

For that matter, I'll bet you could save a TON of money by
feeding your whole family dog food or cat food three times
a day !

The answer is III only, or D.

We can start to solve this by knowing what the HL theorem means. The HL theorem, like its name implies, shows says that if a hypotenuse and leg of a triangle are congruent to the hypotenuse and leg of a different triangle, then the triangles are congruent. The only triangle that we see a hypotenuse congruent in is in figure III. In figure II, those congruent sides are both legs while in figure I we just see 2 congruent angles. Now in figure III, we can also see that two legs are congruent because of the reflexive property. That means that the answer is III, or D.

Josephine noticed that out of 10 e-mails she received, 7 were advertisements. What can she predict about the number of advertise

andriy [413]

She can expect 70 to be ads since there is 10 times more emails so 7 times 10 is 70 so 70 ads

1) Jo Anne needs to do a speech in her English class that can't be more than 4 minutes

djyliett [7]

Answer:

( 0 < y < 23 / 6 ) mins

Step-by-step explanation:

Solution:-

We will define a variable ( x ) as the time it took for Jo Anne to give her speech at home.

The time taken to give her speech must always be less than 4 minutes. We can express this mathematically using an inequality as follows:

( 0 < x < 4 ) minutes

Jo Anne gave her speech which was 10 seconds less than the one she practised at home. We will convert the time in seconds to minutes as follows:

$10 s * \frac{min}{60 s} = \frac{1}{6} min$

The time taken by Jo Anne to complete her speech in English class can be represented as:

y = x - 1/6

Using the range of time that Jo Anne could take in delivering her speech in the class would be:

0 < x < 4

0 - 1/6 < y < 4 - 1/6

-1/6 < y < 23 / 6

Since time can not be less than zero. We correct the lower limit to " 0 " as follows:

( 0 < y < 23 / 6 ) mins

A water storage tank has the shape of a cylinder with diameter 14 ft. It is mounted so that the circular cross-sections are vert

andrezito [222]

Answer:

percentage of the total capacity is 75.6%

Step-by-step explanation:

Hello! To solve this problem we follow the following steps

1. draw the complete scheme of the problem (see attached image)

2. To solve this problem we must find the area of the circular sector using the following equation.(c in the second attached image)

$A=\frac{R^2}{2} (\alpha -sin\alpha )$

$\alpha =2arccos(\frac{d}{R})$

3. observing the attached images we replace the values in the equations and find the area of the circular sector, remember that you must transform the angle to radians

$\alpha =2arccos(\frac{5}{7})=88.83$
