VMariaS [17]3 years ago

3 0

Answer:

f= 0.7

Step-by-step explanation:

Multiply by reciprocal on both sides: 4/3 * 3/4(5f-3) = 3/8 * 4/3 f

Then, you are left with: 5f-3 = 1/2

Then you subtract by three on both sides to get: 5f=3.5

Finally, divide by 5 on both sides to get: f=.07

the dog needs a 1/3 of a cup of dog food each day. the bag holds 5 cups of dog food how many days will it last ?

sleet_krkn [62]

Answer:

15 days

Step-by-step explanation:

You have 5 cups of food, and you give him 1/3 a day.

So, <em>5 divided by 1/3</em>, which would get you 15 days. Or you could cross-multiply, meaning you multiply across, but in this case I just made them line up so you can see how to do it. $(food)/(cupsperday) = 5/\frac{1}{3} \\OR\\\frac{(food)}{1}*(cupsperday) = \frac{5}{1} *\frac{3}{1}$

The area of a triangle is given by the formula A=1/2bh, where A = the area of the triangle, b = the length of the base, and h =

stiks02 [169]

Answer:

The heigh of the triangle is 10cm

Step-by-step explanation:

The area of a triangle is given by the formula A=1/2bh where

A = the area of the triangle,

b = the length of the base, and

h = the height of the triangle.

To find the height when

the

Area of the triangle, A =45cm2,

base of the triangle, = 9 cm long.

Using the formula, A = 1/2 × b × h

45 = 1/2 × 9 × h

Cross multiplying

2×45 = 1×9×h

90 = 9h

h = 90/9 = 10cm

If n is an odd, prime integer and 10n19, which is true about the mean of all possible values of n? 0 A. It is greater than the m

steposvetlana [31]

Answer:

B. It is greater than the median.

Step-by-step explanation:

If n is an odd, prime integer and 10<n<19, then the true statements about the mean of all possible values of n are:

B. It is greater than the median.

Here, n can be 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18.

But as n is odd , it can be 11, 13, 15 and 17.

And also it is given that n is prime, so we will cancel out 15.

Now we are left with 11, 13 and 17.

Their mean is = $\frac{11+13+17}{3}$ = 13.66

Median is 13, that is smaller than 13.66.

So, we can see that the mean is greater than median.
