Answer:

16 inches

Step-by-step explanation:

The tile is rectangular, so the other 2 sides have lengths 2in and 6in.

The perimeter is 2in + 6in + 2in + 6in = 16in

Answer:

16

Step-by-step explanation:

the long sides are both 6 inches

6+6=12

the short sides are both 2 inches

2+2=4

add all the sides together

12+4=16

The measure of BC is 24 cm. So, option B is correct.

Important information:

We need to find the measure of BC.

We have,

AD = AB = 10 cm

We know that the radius of a circle is perpendicular to the tangent at the point of tangency. It means triangle ABC is a right angle triangle.

Using the Pythagoras theorem, we get

[tex](AB)^2+(BC)^2=(AC)^2[/tex]

[tex](10)^2+(BC)^2=(26)^2[/tex]

[tex](BC)^2=676-100[/tex]

[tex](BC)^2=576[/tex]

Taking square root on both sides, we get

[tex]BC=\sqrt{576}[/tex]

[tex]BC=24[/tex]

The measure of BC is 24 cm. So, option B is correct.

Step-by-step explanation:

The area of a triangle is always base times half height. Since this triangle has a 90° corner, the vertical 4 inch is also the height.

So area is 4*4/2 = 8

Answer:

Answer: Add 315 gallons of 70% antifreeze to 90 gallons of 25% antifreeze to make a 60% mixture.

You need to end up a mixture that is 60% antifreeze.

You have 90 gallons of 25% antifreeze, which means it has .25*90 = 22.5 gallons of pure antifreeze mixed with a solvent (probably water).

.

You will add 'x' gallons of 70% antifreeze to make the 60% mixture.

So, at the conclusion, you will have (90+x) gallons  60% 'pure' antifreeze. That can be shown with the equation:

.

.25*90 + .7*x = .6*(90+x)

.

Multiply by 100 to eliminate fractions.

.

25*90 + 70x = 60(90 +x)

.

2250 + 70x = 5400 + 60x

.

10x = 5400 -2250

.

10x = 3150

.

x = 315 gallons of 70% antifreeze.

.

How much will you end up having on hand?

90 + 315 = 405 gallons

.

If it is 60% antifreeze, how much 'pure' antifreeze will be in the mixture?

.6*405 = 243

.

In the original 90 gallons, you have 22.5 gallons of pure antifreeze.

In the additional 315 gallons, you have .7*315 = 220.5 gallons.

22.5+220.5 = 243 gallons

Answer:

The Answer to 3-6 is -3!

Step-by-step explanation:

Think of it as a regular problem at first, 6-3: Switch the rolls!

6-3= 3 So when you switch the numbers back to 3-6, you get -3.

The answer has to have a negative sign (-) because it is a negative, a number below zero.

3-3= 0, 3 is half of 6, 6 is the number you need to subtract so you have to go below zero because subtraction is all about taking away from that first number. So 3-3= 0, 0-3= -3.

Answer:

Step-by-step explanation:

Given that sin theta = √3/√7

Opposite =√3

Hypotenuse = √7

Get the adjacent

Adj² = (√7)²-(√3)²

Adj² = 7-3

Adj² = 4

Adj = √4

Adj = 2

Cos theta = adj/hyp = 2/√7

csc theta= 1/sin theta = 1/(√3/√7) =

√7/√3

sec theta= 1/costheta = 1/(2/√7) = √7/2

tan theta= opp./adj = √3/2

cot theta =1/tan theta = 1/(√3/2) = 2/√3

= 2√3/3

Scale factor is the ratio of the corresponding sides:

Find m using the scale factor:

Answer:

scale factor is 4 and m is 16.

Step-by-step explanation:

This is because these are similar rectangles, so the proportion of each side to the congruent side is the same. This means that to get from 7 to 28 u multiply by a scale factor of 4, and to get m you would multiply 4 by 4.
