Answer:

32

Step-by-step explanation:

twelve less than 32 is 20.

its very simple really, just do 20+12 or 12+20 either way its 32

have a great day :D

Answer:

If it's twelve less than a number is 20 then 32 is the answer.

Answer:

B'C' = 2 units

Step-by-step explanation:

The dilation performed makes ∆A'B'C' (sketched flag) similar to ∆ABC (actual flag).

Given that, A'B' = 8 units, AB = 24 ft, and BC = 6 ft, therefore:

A'B'/AB = B'C'/BC

Substitute

8/24 = B'C'/6

Cross multiply

24*B'C' = 8*6

24*B'C' = 48

B'C' = 48/24

B'C' = 2 units

Answer: the answer is 66

Step-by-step explanation: 180-90-24=66

Well the sum of all the angles of a triangle is 180˚ so 24+90=114˚

180˚-114˚=66˚.

Answer:

x = [tex]\frac{\sqrt{12} }{3}[/tex]12 = 8[tex]\sqrt{3}[/tex]

y = [tex]\frac{\sqrt{3} }{3}[/tex]12 = 4[tex]\sqrt{3}[/tex]

Let me know if you need some help simplifying the expressions or o the trig side of things

Step-by-step explanation:

I'm not sure if this is full out trig or recognizing special triangles, specifically 30-60-90 triangles.  Of course since one angle is 30 degrees and the other is 90 degrees this is a 30-60-90 triangle.

with 30-60-90 tringles  the basic guide is as follows.

The three legs will be referred to as the hypotenuse, short leg and long leg.  I will use H, S and L.  

H = 2S = [tex]\frac{\sqrt{12} }{3}[/tex]L

S = .5H = [tex]\frac{\sqrt{3} }{3}[/tex]L

L = [tex]\frac{\sqrt{3} }{2}[/tex]H = S[tex]\sqrt{3}[/tex]

If this is trig just break out the unit circle and SOH CAH TOA

So x is the hypotenuse, and y is the short leg and we know the long leg is 12, so we can use that.

to find the hypotenuse knowing the long leg we use H = [tex]\frac{\sqrt{12} }{3}[/tex]L and to find the short leg with the long leg you use S = [tex]\frac{\sqrt{3} }{3}[/tex]L.  now just plug in 12 for L

Step-by-step explanation:

As long as you know that the two shapes are similar, you can use one dimension on both figures to calculate the scale factor. For example, if you know the width of the shape, divide one width by the other to find the scale factor.

Answer:

Angle ABC: 110°

Angle XYZ: 75°

Answer:

Abc is 110

xyz is 75

Step-by-step explanation:

If you look at abc it is a obtuse (more than 90) and 110 is the only one over 90

xyz is a acute angle meaning less than 90. there are 2 possible answers but it is so close to being 90 degrees that i have to say its 75

Answer:

The volume of old box storage is greater Than the volume of plastic container, hence, Devon's clothing will not fit into the plastic container.

Step-by-step explanation:

Converting inch measures to feet :

1 inch = 0.0833 feets

Volume of rectangular prism :

V = Lenght * width * height

Volume of plastic container:

16 in = 16 * 0.0833 = 1.3328 feets

13 in = 13 * 0.0833 = 1.0829 feets

Volume of plastic container :

V = 1.3328 * 1.0829 * 1.75 = 2.526 ft³

Volume of box :

1.5 * 1.5 * 14 = 31.5 ft³

The volume of old box storage is greater Than the volume of plastic container, hence, Devon's clothing will not fit into the plastic container.

Step-by-step explanation:

A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.

In this case:

1) Diameter = 18 km (given)

  Radius = 18/2 = 9 km

2) Diameter = 1 x 2 = 2 m

   Radius = 1 m (given)

3) Diameter = 17 x 2 = 34 cm

   Radius = 17 cm (given)

4) Diameter = 50 mm (given)

  Radius = 50/2 = 25 mm

John has a swimming pool, in which the center of the pool to the edge is 3 meters. What is the diameter? Simply multiply 3 with 2:

3 x 2 = 6 meters

6 meters is the diameter.

Given:

The figure of a quadrilateral ABCD.

To find:

The supplement of angle ABC.

Solution:

We know that, two angles are called supplementary angles if their sum is 180 degrees.

[tex]\angle ABC+\angle BAC=110^\circ+40^\circ[/tex]

[tex]\angle ABC+\angle BAC=150^\circ\neq 180^\circ[/tex]

So, [tex]\angle BAC[/tex] is not a supplement of [tex]\angle ABC[/tex].

[tex]\angle ABC+\angle ADC=110^\circ+90^\circ[/tex]

[tex]\angle ABC+\angle ADC=200^\circ[/tex]

So, [tex]\angle ADC[/tex] is not a supplement of [tex]\angle ABC[/tex].

[tex]\angle ABC+\angle DAB=110^\circ+(40+30)^\circ[/tex]

[tex]\angle ABC+\angle DAB=110^\circ+70^\circ[/tex]

[tex]\angle ABC+\angle DAB=180^\circ[/tex]

So, [tex]\angle DAB[/tex] is a supplement of [tex]\angle ABC[/tex].

In the same way [tex]\angle ABC+\angle BDC\neq 180^\circ[/tex].

So, [tex]\angle BDC[/tex] is not a supplement of [tex]\angle ABC[/tex].

Therefore, the correct option is C.

Answer:

To divide by a decimal, multiply the divisor by a power of ten to make the divisor a whole number. Then multiply the dividend by the same power of ten. You can think of this as moving the decimal point in the dividend the same number of places to the right as you move the decimal point in the divisor.
