Somebody help #9 geometry

Answer:

400

Step-by-step explanation:

The number of eagle quarters likely to be in the bag is 200.

Option B is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of quarters = 500

Out of the 10 quarters.

Eagle quarters = 4

This means,

Percentage of eagle quarters,

= 4/10 x 100

= 40%

Now,

40% of 500 quarters.

= 40/100 x 500

= 200

Thus,

The full bag is likely to have 200 eagle quarters.

Answer:

You can try a picture memory method to help students

An example write down notes of what the triangle laws are for angles.

Then interpret them into your picture measurement theory.

Example could be the perpendicular measures of a right angle can be used

to find an area would be the M but as we are finding angles we could use the Big A instead of degrees sign.

We could provide pictures of cars to represent trigonometry

Where back wheels opposite angles and sides from slant are both the unit measure used in  Side/sin( A) x sin (B)   so this way you label the car wheel angle above of the square boot 'side on' and this angle is A

The B is the one above it linking the slant to find the other measure.

You are asked to design a theme around measuring angles so you need to look at other sin cos and tan calculus to design a picture that can create an image like i've given to find slant.

You need to one that finds angles.

However if you do find a car can help you can always call it square boot as in square root, considering 2/3 of sin cos and tan are square root measures.

Step-by-step explanation:

See the attached ideas and trigonometry

Picture memory Trigonometry

Picture 1. Sunrise Ah side looks for side measure.

The number above is the hypotenuse

A/H = cos ( ) x hyp =base A/H = cos ( ) x hyp = side

Picture 2.Sunrise Soh looks for side measure.

The number above it is the hypotenuse

O/H = sin ( ) =p (for product) take the p x hyp.

Picture 3 Sunrise Toast (Toa) looks for side measure = O/A

Tan ( lower angle ) x base = side

Picture 4 Side of car (Soh) with window as hypotenuse.

Two wheels are the 2 angles given and the back seat is perpendicular to both wheels =

so the triangle structure looks like this /00|7

so you type in 7/sin ( 1st wheel) x (2nd wheel) = hypotenuse.

Both angles given or worked out this is when this is used.

Picture 5 Electric mast looking for slope SIN =S/P = O/A

Angle at top

We have the side at 70 and looking for the slope

Sin( top angle) = p then side/p = hyp

Picture 6

Top angle and base given creates a T this means half both of them before dividing.

To find hypotenuse

Half = 1/2 base / sin (1/2) = hypotenuse

Picture 7

Top angle and base given creates a T this means half both of them before dividing.

To find height =

Half = 1/2 base /Tan 1/2) = Triangle height.

Key checker after pictures are drawn is;

sunrise = low angle x side or low angle x base = hypotenuse.

car = backseat x wheels = hypotenuse always remember when car on side the first

wheel first, second wheel 2nd first in the calculator. The wheels are the 2 angles that

make the car when flipped.

Half = 1/2 base / sin (1/2) = hypotenuse

Half = 1/2 base / tan (1/2) = height

Just take care with top angle and lower angle key words in the drawing descriptions and then the pictures will help.

Answer:

10 grams or 0.010kg

Step-by-step explanation:

The mass of the bag used to make flour is 2.26 kg = 2260 grams

Now, in order to find out how many badges she made, we would need to divide the weight of the bag by the amount needed to make a badge.

Therefore: [tex]\frac{2260}{450} = 5.02[/tex]

We know now that the bag will make 5 batches and will have some left over. In order to find how much we used, we can multiply 5 * 450 = 2250.

Therefore, in order to make 5 batches, Maria used exactly 2250 grams of flour which in result left us with 10 grams of the bag.

Note: 2260 -2250 = 10 grams.

Subtract, in order to find how many you have left.

Hope this helps.

After making one batch of muffins, Maria will have 1.8 kg of flour remain.

What is 1 kg when it is converted into grams?

1 kg will be 1000 grams when converted.

Given,

Maria bought 2.26 kg of flour = 2260 grams of flour.

To make 1 batch of muffins, Maria needs 450 grams of flour.

Therefore, the flour Maria has after making one batch of muffin = (2260 - 450) grams = 1810 grams.

Answer:

volume of the hemisphere   ≈1577.5 cm³

Step-by-step explanation:

To find the formula for calculating the volume of a hemisphere, we will follow the steps below:

write the formula for calculating the volume of a hemisphere.

volume of a hemisphere = volume of a sphere ÷2

                                        = [tex]\frac{4}{3}[/tex]πr³   ÷   2

                                        =[tex]\frac{2}{3}[/tex] πr³

WHERE r is the radius

from the question given, radius= 9.2 cm  

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the equation

volume of a hemisphere =  [tex]\frac{2}{3}[/tex] πr³

                                          = [tex]\frac{2}{3}[/tex] × 3.14 ×9.2³

                                           = [tex]\frac{2}{3}[/tex] × 3.14 ×753.571

                                          ≈1577.5 cm³   to the nearest tenth of cubic centimeter

volume of the hemisphere   ≈1577.5 cm³

Step-by-step explanation:

Answer:

Step-by-step explanation:

To solve this problem, we just need to find the common point of these linear function, beacuse they form a piecewise function which is continuous according to the problem, that means they are related by one common point.

Let's solve the following expression [tex]f(x)=g(x)[/tex], where [tex]f(x) =2x+2[/tex] and [tex]g(x)=4x[/tex]. So,

[tex]2x+2=4x\\2=4x-2x\\2x=2\\x=1[/tex]

Which means [tex]n=1[/tex], that is, if the n is greater than 1, then the function is defined by [tex]f(x)[/tex], if the n is least or equal than 1, then the functioni is defined by [tex]g(x)[/tex]

Therefore, the right answer is D.

Answer:

1. A, -1

2. D, 1

3. B, It is discontinuous because there is a value a for which f(a) is not defined 4. D, It is discontinuous because there is a value a such that lim f(x) does not exist

[tex](a)F \cup H=(3, \infty)\\(b)F \cap H=(6, \infty)[/tex]

Step-by-step explanation:

Given the sets F and H of real numbers defined as given:

F={w | w>3}

H={w | w>6}

To write a set in interval  notation, we use these brackets, (  ) for < or > while we use [ or ] for [tex]\leq $ or \geq[/tex].

Since our sets are defined by strict inequalities(< or >)

In interval notation

[tex]F=(3,\infty), H=(6,\infty)[/tex]

[tex](a) F \cup H =(3,\infty) \cup (6,\infty) \\\\F \cup H=(3, \infty)\\\\(b) F \cap H =(3,\infty) \cap (6,\infty) \\\\F \cap H=(6, \infty)[/tex]
