Answer:

The numbers are 12 and 14 ONLY

Step-by-step explanation:

To find the answer, set up an equation.

Set

equal to the lower number, and

as the higher number since they are consecutive even numbers so they are two apart.

Now write out the equation according to the question

(

Formula to find the surface area of a triangular prism

AleksAgata [21]

Step-by-step explanation:

In the mensuration of a triangular prism we can find the total surface area by solving for the areas of individual shape.

The triangular prism consist of

1. three rectangular surfaces

2. two triangular surfaces.

Hence the total surface area is the sum of the areas of the rectangular surface

= $(l* w) +( l*w)+(l*w)\\$

and the sum of all areas of triangular surfaces

= $(\frac{1}{2}bh) + (\frac{1}{2}bh)$

In summary just find the area of each shape and add them together.

I'm am very confused with this question.

stich3 [128]

Answer:

103°

Step-by-step explanation:

This is a cyclic quadrilateral (all vertices on the same circle)

Opposite angles are supplementary:

∠A + ∠C = 180°
∠B + ∠D = 180°

Find x:

x + 5 + x - 7 = 180°
2x - 2 = 180°
2x = 182°
x = 91°

Find D:

∠D = x - 14°
∠D = 91° - 14° = 77°

Find B:

∠B = 180° - 77° = 103°

Lin is reading a 47-page book. She read the first 20 pages in 35 minutes.

bekas [8.4K]

Answer:

22.25 minutes

Step-by-step explanation:

First determine how long it will take her to read the entire book

20 pages 47 pages

-------------- = ----------------

35 minutes x minutes

Using cross products

20x = 35*47

20x=1645

Divide by 20

20x/20 = 1645/20

x =82.25 minutes

This is more than 1 hour ( 1 hour = 60 minutes)

82.25 minutes - 60 minutes = 22.25 minutes

She will need 22.25 more minutes
