Answer:

24

Step-by-step explanation:

2/10

120 ÷ 10 = 12

2 x 12 = 24

10 x 12 = 120

24/120

Answer:

24

Step-by-step explanation:

120 % 10  = 12

2 x 12 = 24

Answer:

Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.

You would have to find a GCF (greatest common factor) and multiply it out of the radical.

ex.

[tex]\sqrt{6}[/tex] = 2 x 2 x 2

when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2

2[tex]\sqrt{2\\}[/tex]

so [tex]\sqrt{6}[/tex] would be closest to the positive 2 on the number line and 2 notches.

[tex]\sqrt{11}[/tex]

is an irrational number, so it might fall into 3.3 if turned into a decimal.

Step-by-step explanation:

Answer:

1)Area; A = ¼πr²

Perimeter; P = πr/2 + 2r

2)A = 19.63 cm²

P = 17.85 cm

3) r = 8.885 cm

4) r = 14 cm

Step-by-step explanation:

This is a quadrant of a circle. Thus;

Area of a circle is πr². A quadrant is a quarter of a circle. Thus;

Formula for Quadrant Area is; A = ¼πr²

A) Perimeter of a circle is 2πr. Thus, perimeter of a quadrant is a quarter of the full circle perimeter.

Formula for the quadrant perimeter in the image given is;

P = 2πr/4 + 2r

P = πr/2 + 2r

B) When r is 5 cm;

A = ¼π(5)²

A = 19.63 cm²

P = π(5)/2 + 2(5)

P = 17.85 cm

C) when A is 100cm²:

¼πr² = 100

r² = 100 × 4/π

r² = 78.9358

r = √78.9358

r = 8.885 cm

D) when P = 50 cm.

50 = πr/2 + 2r

50 = (½π + 2)r

r = 50/(½π + 2)

r = 14 cm

Answer:

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

Answer:

Cary is wrong

Step-by-step explanation:

4* (6-4)= 4* 2=8

I think it is saying (8*2) divided by to, which in that case is 8,

but if it is asking 8 (2/2) then that would also be 8 I believe. I really hope this is correct and you have a great day :)

Answer:

x=2

Step-by-step explanation:

Set up a ratio

6/(x+1)=10/(2x+1)

cross multiply

6(2x+1)=10(x+1)

12x+6=10x+10

12x-10x=10-6

2x=4

Answer:

81

Step-by-step explanation:

4/9=36/81

Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.

The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;

Rate of change = Depth/time

Making depth the subject of formula, we have:

Depth = Rate of change × time

Substituting the given parameters into the formula, we have;

Depth = 12 × 4

Depth = 48 feet.

Answer:

t= -8

Step-by-step explanation:

-8t= 64

t= 64/-8= -8

hope it helps! please mark me brainliest..

thank you!! have a good day ahead

Answer:

t = -8

Step-by-step explanation:

Knowing eight times eight equals 64, I knew that is the answer. So, instead of positive eight, it would have to be negative given a negative times a negative equals a positive.

-8 x -8 = 64

I hope this helps!

z = 106

y = 74

Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.

Answer:

850 but im not sure lol

Step-by-step explanation:

645 + 225 = 870

1,320 - 870 = 450

450 + 350 = 800

800 + 50 = 850

Answer: x=6

Step-by-step explanation:

-6x+8=4(5-x)

-6x+8=20-4x

12=2x

x=6

Answer:

-6

Step-by-step explanation:

-6x+8=20-4x

subtract 8 from both sides:

-6x+8-8=20-4x-8

simplifiy:

-6x=-4x+12

Add 4x to both sides:

-6x+4x=-4x+12+4x

simplifiy:

-2x=12

divied both sides by -4:

-2x/-2=12/-2

simplifiy:

x=-6

Answer:

x=121 degrees

Step-by-step explanation:

The extetior angle theorem states that one exterior angle is equivalent to the sum of the opposite two interior angles. So, we can say that x is the sum of the opposite two interior angles, (53 and 68), and 53+68=121.

Answer:

SAS

Step-by-step explanation:

the lines in the middle of a segment mean that they are equal in length.

So OE = EB and AE = EC.

Now, since angle AEB and angle DEC are vertical angles, they are equal.

Therefore the triangles are equal by SAS

Answer:

[tex]Height = 30cm[/tex]

[tex]Length = 360cm[/tex]

Step-by-step explanation:

Given

Scale Measurement

[tex]Height = 2cm[/tex]

[tex]Length = 24cm[/tex]

Required

Determine the possible actual measurement

First, calculate the equivalent ratio.

[tex]Ratio = \frac{Length}{Height}[/tex]

[tex]Ratio = \frac{24cm}{2cm}[/tex]

[tex]Ratio = 12[/tex]

To do this, we pick a scale factor.

Assume the scale factor is 15.

The actual measurement will be:

[tex]Height = 2cm * 15[/tex]

[tex]Height = 30cm[/tex]

[tex]Length = 24cm * 15[/tex]

[tex]Length = 360cm[/tex]

When the scale ratio is calculated, we have:

[tex]Ratio = \frac{Length}{Height}[/tex]

[tex]Ratio = \frac{360cm}{30cm}[/tex]

[tex]Ratio = 12[/tex]

Note that both have the same equivalent ratios of 12.

So, whatever the scale ratio you use, the equivalent ratio will be the same
