Answer:

45 square centimeters

Step-by-step explanation:

The area of the triangle is given by ...

A = (1/2)bh

where b is the base, 2 cm + 3 cm = 5 cm, and h is the height, 6 cm.

A = (1/2)(5 cm)(6 cm) = 15 cm^2

The area of the rectangle is given by ...

A = bh

where b is the base, 12 cm, and h is the height, 2.5 cm.

A = (12 cm)(2.5 cm) = 30 cm^2

The area of the whole figure is the area of the triangle added to the area of the rectangle:

drawing area = 15 cm^2 + 30 cm^2 = 45 cm^2

If a baker doubles a recipe that calls for 6-2/3 cups of flour. How many cups will be needed in all?

Hey there!

The easiest way I could think to do this is by converting your mixed number to an improper fraction and multiplying the fraction by 2, or 2 over 1.

$6 \frac{2}{3} = 6*3+2 = \frac{20}{3}$

$\frac{20}{3} * \frac{2}{1}$

To multiply fractions, you can just multiply the numerators and denominators and simplify, if applicable.

$\frac{20}{3} * \frac{2}{1} = \frac{40}{3}$

Since you can't simplify this fraction in its improper form, just convert it back into a mixed number.

$\frac{40}{3} = 13 \frac{1}{3}$

So, your answer will be $13 \frac{1}{3}$ .

Hope this helped you out! :-)

What is the value of the expression below when x=4x=4? 7x^2 +8x-7 7x 2 +8x−7

Vinil7 [7]

Answer: 137

Step-by-step explanation:

The given expression: $7x^2 +8x-7$

We need to find the value of the expression when x=4.

So we just use the substitution property and substitute the value of x= 4 in the given expression , we get

$7(4)^2+8(4)-7\\\\= 7(16)+32-7\\\\= 112+25\\\\=137$

Hence, the value of the expression at x=4 is 137.

Here is the scale model of a fountain at a museum the scale is 1:30 how many boulders are in the real fountain

wlad13 [49]

Answer:

When we do a scale model of something (like a building, a house, or whatever) al the properties of the original thing must also be in the model.

So for example, you want to do a model of a house, and in the backyard of the house there are 4 trees, then in the model of the house you also need to put 4 trees in the backyard (indifferent of the scale of the model).

Then the number of boulders in the really fountain should be the same as the number of boulders in the scale model of the fountain.
