zalisa [80]

To multiply fractions, you multiply numerator with numerator and denominator with denominator

In other words: a/b*c/d=(a*c)/(b*d)

So 1st one is (5*2)/(6*3) which is 10/18 or 5/9 simplified

2nd one is (9*5)/(10*18) which is 45/180 or 1/4 simplified

3rd one is (4*3)/(5*4) which is 12/20 or 3/5 simplified

4th one is (2*5)/(3*1) which is 10/3 or 3 1/3 if you want a mixed number

Hope this helped!

What is the area of the figure below?
fgiga [73]

Answer:

Option a 26 inches square

Step-by-step explanation:

Given in the picture is a triangle with 3 sides as 10.8 inches, 5 inches and base =10+3 = 13 inches

The altitude for base 13 inches is shown as 4 inches.

We know that for any triangle area

=1/2 * base * height

Here base = 13 and height = 4

Hence area = 1/2 (13)(4) = 26 inches square

Answer is option a

---

This can be done in another way also

There are two triangles one with base 10 inches and height 3 inches and another with base 3 inches and height 4 inches

Area of combined figure = sum of area of two triangles

= 1/2 (10)(4) +1/2(3)(4) =

20+6

=26 square inches

Find the lateral area of the regular prism with height h, if the base of the prism is: Equilateral triangle with the side 4 cm a
Shtirlitz [24]

Equilateral triangle with the side 4 cm and h=2.5 cm

In equilateral triangle all sides are equal

so all sides are equal in the base of the prism

lateral area of the prism = Perimeter of the base * height

Perimeter of the base equilateral triangle = side + side + side

lateral area of the prism =(side + side + side) * height

= (4+4+4) * 2.5

= 30 cm^2

lateral area of the prism = 30 cm^2

A juice recipe calls for 5 cups of grape juice for every 2 cups of peach juice are needed for a batch that uses 8 cups of peach
Ksivusya [100]

Answer: 20 cups of grape juice are needed for 8 cups of peach juice.

Step-by-step explanation:

5 times 4 is 20.

We must do this step because you need 2 cups for 1 batch, and times 4 that is 8. So then we multiplied 5 times 4.

So, 20 cups of grape juice are needed for 8 cups of peach juice.

Hope this answer helps you out!
