Cora makes a scarf with cloth rectangles and triangles. For every 5 pieces of cloth, 2 are rectangles. She needs 15 pieces of cl

PtichkaEL [24]

Answer: There are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.

Explanation:

Since we have given that

For every 5 pieces of cloth, 2 are rectangles

So, remaining piece will be of triangle so,

$5-2=3$

3 are triangles.

Ratio of rectangles to triangles is 2:3.

Now, she needs 15 pieces of cloth to complete her scarf,

So, Number of rectangles is needed is given by

$\frac{2}{5}\times 15\\\\=2\times 3\\\\=6$

Number of triangles is needed is given by

$\frac{3}{5}\times 15\\\\=3\times 3\\\\=9$

Hence, there are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.

Which equation can be used to calculate the surface area of the triangular prism net show below?

slava [35]

The equation that can be used to calculate the surface area of the triangular prism net shown below is mathematically given as

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

<h3>Which equation can be used to calculate the surface area of the triangular prism net shown?</h3>

Generally, The region or area that is occupied by the surface of any particular item is referred to as that object's surface area.

In conclusion, the equation surface area of the triangular prism will be one that accommodates all parameters

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

Can I get help with both or one. please and thank you!!!

Pavlova-9 [17]

14. The answer is A; 8 is the opposite reciprocal of -1/8, which is what you need for perpendicular slope.
15. The answer is C; you can guess and check by plugging points into the equation.

The volume of the cylinder below is 225 pi cubic centimeters. If you doubled the radius of the of cylinder, which statement belo

Oduvanchick [21]

The volume of the cylinder will be 900π cube cm.

Step-by-step explanation:

Given,

The volume of the cylinder 225π cube cm

Let the radius be r and the height be h.

To find the volume when the radius is doubled.

Formula

The volume of cylinder = π $r^{2} h$

According to the problem,

π $r^{2} h$ = 225

When the radius is 2r the volume will be = π $(2r)^{2} h$

=4π $r^{2} h$

=4×225π cube cm

= 900π cube cm
