The table shows the width and length of different pictures that Coby has enlarged for the school yearbook: Enlarged Pictures Wid

Savatey [412]

Answer:

42 inches

Step-by-step explanation:

Im guessing that the the table looks like this:

Width Length

3 7

6 14

9 21

So we can see the numbers on the right are increasing by 3 and the numbers on the left are increasing by 7.

The width is 3 times some number, and the length is 7 times the same number.

So if the width was 18 then we know the number would be 3 because 3 * 6 = 18

If that number is 6, then the length will be 6 * 7 = 42

So the length is 42 inches

What’s the correct answer for this question?

Ad libitum [116K]

Answer:

C:

Step-by-step explanation:

Both angles add up to 180°

<BCG + <BFG = 180°

2x+146+4x+238=180

6x+384 = 180°

6x = 180-384

6x = -204

Dividing both sides by 6

x = -34

The perimeter of equilateral triangle ABC is 81/3 centimeters, find the length of the radius and apothem.

MAXImum [283]

There is a typo error, the perimeter of equilateral triangle ABC is 81/√3 centimeters.

Answer:

Radius = OB= 27 cm

Apothem = 13.5 cm

A diagram is attached for reference.

Step-by-step explanation:

Given,

The perimeter of equilateral triangle ABC is 81/√3 centimeters.

Substituting this in the formula of perimeter of equilateral triangle = $3\times\ side$

$3\times\ side$ $=[tex]81\sqrt{3}$

$Side = \frac{81\sqrt{3} }{3} =27\sqrt{3} \ cm$

Thus from the diagram , Side $AB=BC=AC= 27\sqrt{3} \ cm$

We know each angle of an equilateral triangle is 60°.

From the diagram, OB is an angle bisector.

Thus $\angle OBC = 30$ °

Apothem is the line segment from the mid point of any side to the center the equilateral triangle.

Therefore considering ΔOBE, and applying tan function.

$tan\theta =\frac{perpendicular}{base} \\tan\theta=\frac{OE}{BE} \\tan\theta=\frac{OE}{\frac{27\sqrt{3}}{2} } \\tan30\times {\frac{27\sqrt{3} }{2} }= OE\\\frac{1}{\sqrt{3} } \times\frac{27\sqrt{3} }{2} =OE\\$

Thus ,apothem OE= 13.5 cm

Now for radius,

We consider ΔOBE

$cos\theta=\frac{base}{hypotenuse} \\cos30= \frac{BE}{OB} \\Cos30 = \frac{\frac{27\sqrt{3} }{2}}{OB} \\OB= \frac{\frac{27\sqrt{3} }{2}}{cos30} \\OB= \frac{\frac{27\sqrt{3} }{2}}{\frac{\sqrt{3} }{2} } \\OB =27 \ cm$

Thus for

Perimeter of equilateral triangle ABC is 81/√3 centimeters,

The radius of equilateral triangle ABC is 27 cm

The apothem of equilateral triangle ABC is 13.5 cm

Talia uses 10 strawberries and 4 oranges to make 8 servings of fruit salad. How many strawberries for 12 servings?

gayaneshka [121]

For 8 servings, Talia uses strawberries = 10
For 1, it is = 10/8

Now, for 12 servings, it would be: 10/8 * 12 = 10/2 * 3 = 5 * 3 = 15

In short, Your Answer would be 15 strawberries

Hope this helps!
