Answer:

168ft^2

Step-by-step explanation:

Surface Area = total area of all the faces of the figure.

Area of a triangle:

$\frac{1}{2}bh$

2 * (1/2(6)(4)) + 2 * (5 * 9) + 6 * 9

= 168

Mrs.Manning is making cookies for the bake sale. She jas 3/4 cup of flour and needs 1/3 cup of flour for her chocolate chip cook

Sedbober [7]

Answer:

<em>The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9</em>

Step-by-step explanation:

<u>Fraction of Portion</u>

Suppose we have a number n and another number m such as m>n. The portion or fraction of size n of m is given by the quotient n/m.

For example, 3 pieces of cake out of a total of 6 make them a fraction of 3/6 = 1/2 of the whole cake, i.e. half of the total available.

Mrs. Manning needs 1/3 cup of flour to make cookies for the bake sale. She actually has 3/4 cups of flour. Calculate the fraction of needed against the available flour:

$\displaystyle \frac{\frac{1}{3}}{\frac{3}{4}}$

The division can be easier performed by multiplying by the reciprocal of the denominator:

$\displaystyle \frac{1}{3}\cdot \frac{4}{3}=\frac{1*4}{3*3}$

$\displaystyle =\frac{4}{9}$

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

There are approximately 2.7 million deaths per year in country A what are the deaths per minutes

kompoz [17]

To solve:

Divide 2,700,000 by 365 to find the number of deaths per day.

2700000/3562700=7397.26

Then divide that number by 24 to find the deaths per hour.

7397.26/24=308.22

Finally, divide 308.22 by 60 to find deaths per minute.

308.22/60=5.14

Answer: There are about 5 deaths per minute in Country A.
