Answer: [tex]40\sqrt{3}[/tex]

Step-by-step explanation:

30-60-90 triangle- leg opposite 30 is x, leg opposite 60 is [tex]x\sqrt{3}[/tex] and the hyp. is 2x

we need to figure out X

we also know that the leg opposite 60 is = 120

[tex]120=x\sqrt{3}[/tex]

square everything

0; 0.125; 0.375; 0.5; 0.625; 0.75; 0.875; and 1.00.

Looking at these decimals, 1.00 is the greatest amount as it is the only fraction that converted to a whole number.

Answer:

a fraction is a numerical quantity that is not a while number; aswell as a small ot tiny part, amount, or proportion of something. fractions represent equal parts of a whole or a collection. example of a fraction: 1/4, 1/2, 1/25, ect.

Answer: 5/30 chance of it happening

Step-by-step explanation:

The probability is 5/30 chance of it happening.

We have given that,

In a class of students, the following data table summarizes how many students have a brother or a sister.

We have to determine the probability that a student chosen randomly from the class has a sister.

The probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).

Therefore the probability is 5/30 chance of it happening.

Answer:

1/4 or 25%

Step-by-step explanation:

The probability for rolling an odd number is 50% or  [tex]\frac{1}{2}[/tex] because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). [tex]\frac{3}{6} =\frac{1}{2}[/tex]

The probability for rolling two odd numbers in a row is

[tex]\frac{1}{2} *\frac{1}{2} =\frac{1}{4}[/tex]

So, the probability of rolling an odd number twice is 25% or  [tex]\frac{1}{4}[/tex].

Answer:

x = 1/2

y = -1/3

Step-by-step explanation:

10x - 9y = 8    (Multiply by 3)

15x + 21y = 0.5 (Multiply by -2)

30x - 27y = 24

-30x - 42y = -1

-69y = 23

y = -1/3

10x - 9y = 8

10x - 9(-1/3) = 8

10x + 3 = 8

Answer:

60

Step-by-step explanation:

They sold 60 baked goods because 75% of 80 is equal to 60.

Answer:

60 baked goods

Step-by-step explanation:

To find the answer to this question, you will need to multiply 80 by 75%.

Now this is very simple.

Some calculators will actually give you the option to multiply by a percent. Just type 80×75% and you'll get 60.

There is another way to do this.

You could also just solve 80×.75 due to the fact that .75 is equal to 75%.

Answer:

w>-12

Step-by-step explanation:

6>w/-2 (Given)

6>-w/2 (Rewrite)

12>-w (Multiply both sides by 2)

-12<w (Remember to flip the sign when dividing or mulitplying by a negative)

w>-12 (Rewrite with w in front)

Therefore, w>-12 is the solution to the inequality.

Answer:

w>-12

Step-by-step explanation:

First, you you need to get rid of the -2 in w/-2 by multiplying -2 by both sides like this.

(-2)6>w/-2(-2)

Then you simplify it like this:

-12>w

However, since you multiplied/divided with a negative, you switch the inequality sign like this:

w>-12

And that's the answer!

Answer:

x=-45/11

y=10/11

Step-by-step explanation:

y = x + 9   eq 1

3x + 8y = -5   eq 2

Re arranging eq 1

x-y=-9

Now multiply  eq 1 with 8

8x-8y=-40   now call as eq 3

Add eq 2 and 3

3x+8y=-5

8x-8y=-40

11x=-45

x=-45/11

put value of x in eq 2 for y

 3(-45/11)+8y=-5

-135/11+8y=-5

8y=-5+135/11

8y=(-55+135)/11

8y=80/11

y=(80/11)*(1/8)

y=10/11

Check

3*(-45/11)+8*(10/11)=-5

-135/11+80/11=-5

(-135+80)/11=-5

-55/11 =-5

-5=-5

Angle of Regular polygon = 166.15° (Approx.)

Step-by-step explanation:

Given:

Regular polygon with 26 sides

Find:

Measure of each angle of Regular polygon

Computation:

Angle of Regular polygon = [(n-2)180] / n

where n = number of sides

Angle of Regular polygon = [(26-2)180] / 26

Angle of Regular polygon = [(24)180] / 26

Angle of Regular polygon = [4,320] / 26

Substitute [tex]x = 3[/tex]

[tex]f(3) = -4 * 3 - 4[/tex]

Answer:

  A)  26°

Step-by-step explanation:

The angle x decreases at a rate that is 12 times the rate of increase of angle y.

  x = 360 -12y

We want x = 2y, so ...

  2y = 360 -12y

  14y = 360

  y = 360/14 ≈ 25.71 ≈ 26

The integer angle closest to y is 26°.

Answer:

Step-by-step explanation:

The rectangle in the middle has a width equal to the radius of the semicircular ends, so (20 cm)/2 = 10 cm.

The semicircular ends, together, make a complete circle of radius 10 cm.

The area is the sum of the areas of the parts:

  A = LW = (21 cm)(10 cm) = 210 cm² . . . . . . rectangle area

  A = πr² = π(10 cm)² = 100π cm² ≈ 314 cm² . . . . . circle area

The total area is ...

  210 cm² +314 cm² = 524 cm² . . . . area of the figure

__

The perimeter of the figure is the sum of the lengths of all of the edges. From the left, working clockwise, we have ...

  P = (1/2 circle of diameter 20) + (rectangle top = 21) +(1/2 circle of diameter 20) +(circle radius = 10) +(rectangle bottom = 21) +(circle radius = 10)

The two 1/2 circles add to a whole circle with a circumference of ...

  C = πd = (3.14)(20 cm) = 62.8 cm

Then the whole perimeter is ...

  P = 62.8 cm + 21 cm + 10 cm + 21 cm + 10 cm = 124.8 cm

Note that we have used 3.14 for pi. If you use a more exact value, your answers will be slightly different.

Answer:

Amount of selling cost = $228

Step-by-step explanation:

Given:

Amount of cost to store = $152

Mark up = 50%

Find:

Amount of selling cost

Computation:

Amount of mark up = Amount of cost to store x Mark up

Amount of mark up = 152 x 50%

Amount of mark up = $76

Amount of selling cost = Amount of cost to store + Amount of mark up

Amount of selling cost = 152 + 76

Amount of selling cost = $228

Answer:

The shop

Step-by-step explanation:

Given

Shop

[tex]Cost = E9[/tex]

[tex]Bag = 12.5kg[/tex]

Supermarket

[tex]Cost=E1.83[/tex]

[tex]Bag = 2.5kg[/tex]

Required

The better value

To do this, we simply calculate the unit price.

This is calculated as:

[tex]Unit = \frac{Price}{Bag}[/tex]

So, we have:

Shop

[tex]Unit = \frac{9}{12.5}[/tex]

[tex]Unit = 0.72[/tex]

Supermarket

[tex]Unit = \frac{1.83}{2.5}[/tex]

[tex]Unit = 0.732[/tex]

At the shop, the unit price is £0.72 per bag while at the supermarket, the unit price is £0.732

The best value is at the shop, because it is cheaper

i.e.

[tex]0.72 < 0.732[/tex]

Step-by-step explanation:

Any triangle formed with one side of the triangle being the diameter of the circle it’s inscribed in will be a right triangle.

6²+8²=c²

36+64=c²

100=c²

√100=c

c=10

So the diameter is 10.  That makes the radius 5.
