Answer:

11.7  (3 s.f.)

Step-by-step explanation:

Given information:

As one of the given angles is 90°, the triangle is a right triangle.

Draw the triangle using the given information (see attached) to help visualize the problem.

To calculate the length of BC, use the sine trigonometric ratio:

[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]

where:

From inspection of the attached triangle:

Substitute the values into the formula and solve for BC:

[tex]\implies \sf \sin(52^{\circ})=\dfrac{9.2}{BC}[/tex]

[tex]\implies \sf BC=\dfrac{9.2}{\sin(52^{\circ})}[/tex]

[tex]\implies \sf BC=11.67496758...[/tex]

[tex]\implies \sf BC=11.7\:\:(3 \:s.f.)[/tex]

The probability of getting two red chips is:

P = 1/21.

The probability of getting a red chip is equal to the quotient between the number of red chips and the total number of chips.

There are 4 blue chips and 3 red chips, for a total of 7 chips.

For the first draw, the probability of getting a red one is:

p = 3/7.

For the second draw, now there are 2 red chips and 6 chips in total, so now the probability is:

q = 2/6 = 1/3

Then the joint probability, given by the product between the two individual probabilities, is:

P = q*p = (3/7)*(1/3) = 1/21.

The measure of ∠ABP and ∠ABC are 32° and 64° respectively.

Any line which divides an angle into two equal halves is a bisector of that angle.

Analysis:

Since the arcs at D and E are drawn with the same radius and arc using center D and E are intersected by line PB( which is the bisector of the full arc with center B) then ∠ABP = ∠PBC = 32°.

∠ABC = ∠ABP + ∠PBC

∠ABC = 32 + 32 = 64°

In conclusion, ∠ABP and ∠ABC are 32° and 64°

The cost of the ice needed to make 50 snow cones is $54.50.

The first step is to determine the volume of the snow cone.

Volume of the snow cone =volume of a cone + volume of the hemisphere

Volume of the cone = 1/3πr²h

1/3 x 3.14 x 10.2 x (8.3/2)² = 183.87 cm³

Volume of the hemisphere = 2/3πr³

2/3 x 3.14 x (8.3 / 2)³ = 224.43 cm³

Total volume = 224.43 cm³ + 183.87 cm³ = 408.30 cm³

Volume of 50 snow cones =  408.30 cm³ x 50 = 20,414.82

Total grams of ice needed = density x volume

0.697 x 20,414.82 = 14,229.13 grams

Convert gram to 1kg

1kg = 1000g

= 14,229.13 grams  / 1000 = 14.23kg

Cost of the ice = 14.13 x 3.83 = $54.50

The correct function shown in the graph is,

⇒ log₁₀ (ax) = 1

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

It has been given that the point (3,1) is on the graph. For the point (3,1) to be on the graph, the following must hold true:

⇒ log₁₀ (ax) = 1

or , ax = 10¹ = 10

Thus, x  = 10/a

So, in order for the point (3,1) to lie on the graph, of all the given options the closest we can get is when we have Option D, that is, when a = 3. That will make x = 3.33 and thus, .

⇒ log (3 × 3.33) = 0.99 ≈ 1

Thus, out of the given options only Option D seems to be the most probable answer.

The linear function that has a different rate of change from y = -3x+4 is A, a function with a y-intercept of -4 that passes through the point (-3,-13)

An intercept is the point where a straight line or a curve meets with the x or y axes.

Analysis:

The rate of change is the same as slope. The slope of y = -3x + 4 is -3,

All other functions Except A have a slope of -3.

for linear function A,

if y = mx + c, c = -4, x = -3, y = -13

-13= -3m - 4

-3m = -9

m = 3

In conclusion, linear function A with a y-intercept of -4 passing through the point (-3,-13) has a different rate of change from y = -3x + 4

Answer:

1. 2507.034 g

2. 1243mg

   0.001243kg

   1,243,000 mcg

3. 162.5g

Step-by-step explanation:

1. First of all we need to convert 30mg and 2.5kg to gram.

⇒ 1 gram = 1000 milligrams

         x     =  35mg  

⇒ 1000mg(x) = 35mg

⇒ x = 35mg    =   35   =  0.035g

        1000mg    1000

Next we convert 2.5kg to gm.

⇒ 1 kilogram = 1000g

     2.5kg   =   x  

(We then criss cross)

⇒ x = 2.5kg × 1000g = 2500g  = 2500g

                 1kg                    1

Now that we converted them all to gram, we will add them.

⇒ 30mg + 2.5kg + 7g = 0.035g + 2500g + 7g = 2507.035 ≈ 2507g

2.  We convert 1.234g into

a. mg

⇒ 1 gram = 1000 milligram

    1.243g = x

⇒ x = 1.243g × 1000mg = 1243mg = 1243mg

                1g                      1

b. kg

⇒ 1 kilogram = 1000gram

                  x =   1.243 gram

⇒ x = 1.243g × 1kg  =   1.243kg = 0.001243kg = 1.243 × 10⁻³ kg

                1000g            1000

c. mcg

⇒  1 gram = 1000000mcg

    1.243g =  x

⇒ x = 1.243g × 1,000,000mcg  = 1,243,000mcg = 1,243,000mcg

                        1 g                                   1

3. We need 500 aspirin, the amount of grams needed and we know that one tablet contains 325mg.

So now we can derive the formula such that:

⇒ 1 tablet      = 325mg

   500 tablet =  x

But first we need to convert 325mg to grams.

⇒ 1 gram = 1000mg

      x   =  325mg

⇒ x = 325mg × 1 g = 325g = 0.325g

              1000mg     1000

So now instead of using 325mg we can use 0.325g.

⇒ 1 tablet   =  0.325g

    500 tablets =  x

⇒ x = 500 tablets × 0.325g  =  162.5g = 162.5g

                      1  tablet                   1
