Answer:

The entire area of the sailboat is 60cm²

Step-by-step explanation:

You can find the area of this shape by breaking it down into simpler shapes and adding up their individual areas.

In this case, the areas we'll use are the rectangle at the bottom, and the pair of triangles at the top.

Because the two triangles can be put together to form a single triangle, we don't need to measure them independently.  We can simply take the total length of their bases, multiply it by their height, and divide by two.  This follows the rule that the area of a triangle is equal to the area of the square that contains it divided by two.

(2cm + 3cm) × 6cm

= 5cm × 6cm

= 30cm²

The rectangle's area is of course equal to its width times its height, so we can say:

2.5cm × 12cm

= 30cm²

The total area of the shapes then is 30cm² + 30 cm², giving us a total area of 60cm²

True [87]

Answer: 100

-200k - 3.01 = 3.3 | · 100

-200k · 100 - 3.01 · 100 = 3.3 · 100

-20,000k - 301 = 330

Suppose y varies inversely with X, and y = 36 when x = 1/12. What inverse variation equation relates x and y?
choli [55]

Answer:

B

Step-by-step explanation:

We are given that <em>y</em> varies inversely with <em>x</em>. Recall that inverse variation has the form:

\displaystyle y=\frac{k}{x}

Where <em>k</em> is the constant of variation.

We are given that <em>y</em> = 36 when <em>x</em> = 1/12. Thus:

\displaystyle (36)=\frac{k}{\left({}^{1}\!/\!{}_{12}\right)}

Solve for <em>k</em>. Multiply both sides by 1/12:

\displaystyle k=\frac{1}{12}(36)=3

Hence, our equation is:

\displaystyle y=\frac{3}{x}

Our answer is B.

A natural food store makes its own brand of trail mix out of dried apples, raisins, and peanuts. One pound of
raketka [301]

Answer:

50.88

Step-by-step explanation:

dried apples,raisins and peanuts. One pound of the mixture is $3.18

it contains twice as much peanuts by weight than apples.

:

One pound of dried apples cost $4.48, a pound of raisins cost $2.40 and

a pound of peanuts is $ 3.44.

:

How many ounces of each ingredient are contained in one pound of the trail mix?

:

Here it is, step-by-step

:

Let a = no. of oz of apples

Let r = no. of oz of raisins

Let p = no. of oz of peanuts

:

The equation:

4.48a + 2.40r + 3.44p = 3.18(16)

:

It says p = 2a, substitute 2a for p

4.48a + 2.40r + 3.44(2a) = 3.18(16)

:

4.48a + 2.40r + 6.88a = 50.88

:

4.48a + 6.88a + 2.40r = 50.88

:

11.36a + 2.40r = 50.88

:

At this point we can say: r = (16-3a), a represents apples & peanuts here.

Substitute (16-3a) for r, solve for a;

11.36a + 2.40(16-3a) = 50.88

:

11.36a + 38.40 - 7.2a = 50.88

:

11.36a - 7.2a = 50.88 - 38.40

:

4.16a = 12.48

a = 12.48%2F4.16

a = 3 oz dried apples

then

P = 2(3)

P = 6 oz of peanuts

:

Find r:

r = 16 - 3 - 6

r = 7 oz of raisins

;

:

Check these values for a, r, p in the cost equation

4.48(3) + 2.40(7) + 3.44(6) = 3.18(16)

13.44 + 16.8 + 20.64 = 50.88; confirms our solutions
