Answer:

(r * g)(x) =30xx + 6x

if it was composition

r (q(x)) =  5(6x) + 1 = 30x + 1

Step-by-step explanation:

Q(x)=6x and r(x)=5x+1

Find (r•q)(x)

multiplying the functions, right?  not composition of functions.

(r * g)(x ) =   (5x + 1) * 6x =   30xx + 6x

(r * g)(x) =30xx + 6x

Answer: The height of the tank is 9.02 feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder = π radius² x height

Replacing with values given:

7252 = 3.14 ( 16 )² h

Solving for h (height)

7252 / 3.14(16)² =h

7252 /3.14 (256) =h

7252 / 803.84 = h

9.02 =h

The height of the tank is 9.02 feet

Answer:

Sue's percentage profit = 9% on each tin of green paint she sells.

Step-by-step explanation:

Litres of green paints mixed = 50 litres

Ratio of litres of yellow paint and litres of blue paint = 1:4.

To determine the litres of yellow paint, we say:

[tex]yellow \: paint = \frac{1}{4} \times 50 = 10 \: litres[/tex]

To determine the litres of blue paint, we say:

[tex]blue \: paint = \frac{4}{5} \times 50 = 40 \: litres[/tex]

Since yellow paint is sold in 5 litres per tin and each tin cost £38; she has 10 litres of yellow paint in all. That implies that she has 10/5 = 2 tin of yellow paint. If one tin cost £38; 2 tin cost 2 × £38 = £76

Similarly,

Since blue paint is sold in 10 litres per tin and each tin cost £58; she has 40 litres of blue paint in all. That implies that she has 40/10 = 4 tin of blue paint. If one tin cost £58; 4 tin cost 4 × £58 = £232

Total cost of yellow and blue paints = £232 + £76

= £308

Since Sue sells all the green paint she makes in 10 litre tins at £89.32 per tin and she has 50 litres in all; we say: 50/10 litres = 5 tins = 5 × £89.32 = £446.60.

Thus, selling price of the green paint = £446.60

[tex]profit \: \% = \frac{selling \: price - cost \: price}{cost \: price} \times \frac{100}{1} [/tex]

[tex]profit \: \% = \frac{446.60 - 308}{308} \times \frac{100}{1} [/tex]

[tex]profit \: \% = \frac{138.60}{308} \times \frac{100}{1} [/tex]

[tex]profit \: \% = 0.45 \times 100[/tex]

[tex]profit \: \% = 45\%[/tex]

Sue's percentage profit for selling all the tins of green paint is 45%, having sold 5 tins. Therefore, Sue's percentage profit for selling each of the paint will be:

[tex]profit \: \% \: on \: each \: green \: tin = \frac{45}{5} = 9\%[/tex]

Hence, Sue's percentage profit for selling each tin of green paint is 9%.

Proof

9% × 5 tins of green paint = 45%

Final answer:

Sue's percentage profit on each tin of green paint she sells is approximately 44.94%. This is calculated by finding the total cost of inputs, subtracting from the total sales revenue, and then finding the profit ratio to the cost.

Explanation:

To calculate Sue's percentage profit on each tin of green paint she sells, we need to first determine the cost of producing the green paint and then subtract that cost from the selling price. The green paint is produced in a ratio of 1:4 yellow to blue paint, making 50 litres total. Therefore, Sue uses 10 litres of yellow paint and 40 litres of blue paint to make 50 litres of green paint.

Yellow paint costs £38 for a 5-litre tin, so two tins are needed (costing £76 total) to get the required 10 litres. Blue paint costs £58 for a 10-litre tin, so four tins are needed (costing £232 total) to get 40 litres. This brings the total cost to £308 for 50 litres of green paint.

Sue sells her green paint at £89.32 per 10-litre tin. Therefore, for 50 litres, she gets 5 tins x £89.32 = £446.60.

The profit Sue makes is the selling price minus the cost price, which is £446.60 - £308 = £138.60. To find the percentage profit per tin, divide the profit by the cost and multiply by 100:

(£138.60 / £308) x 100 = 44.94%

Therefore, Sue's percentage profit on each tin of green paint she sells is approximately 44.94%.

Answer:

Step-by-step explanation:

I mean, you can divide the counters by the range 2 - 38.

I only managed to find out that 38 ÷ 2 = 19.

And 38 ÷ 19 = 2.

It says that there are more than 10 counters in each bag.

So 2 bags is the most liable option.

There are 2 bags and 19 counters in each bag.

Answer:

2 bags, 19 counters.

Step-by-step explanation:

This question is looking for factors of 38 with counters being a factor greater ten and the number of bags being the factor that multiplies the counters to get 38. First, find the factors of 38.

1 x 38 = 38

2 x 19 = 38

Since the problem says bags with an s, we can know that there has to be more than one bag. That leaves us with 2 x 19.

Answer:

option A is the correct one

Step-by-step explanation:

The product of the expression negative 9 x (5 minus 2x) is 18x² - 45x.

The correct option is c) negative 18 x minus 45 x.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given expression:

Negative 9 x (5 minus 2x).

To find the product:

First, we simplify the expression,

-9x (5 - 2x)

Solving the parenthesis,

-9 (5 - 2x)

= -45x + 18x².

= 18x² - 45x.

= 18 x squared minus 45 x

Therefore, 18x² - 45x is the required expression.

The volume of the cone, calculated using the given slant length and diameter, is approximately 18.84 cubic units, therefore the correct answer is B. 18.84 cubic units.

The subject of this question is the volume of a cone. In order to calculate the volume of a cone, you need to use the formula: V = 1/3πr²h. However, in this case, you are given the slant length and the diameter. First, we need to find the radius (r) and the height (h) of the cone. The radius would be half the diameter, so r = 4/2 = 2. Then, from the given slant length (s) and radius (r), we can find the height by using Pythagoras' theorem: h = sqrt(s² - r²) = sqrt(5² - 2²) = sqrt(21). Now we can substitute r and h into the volume formula: V = 1/3*3.14*2²*sqrt(21) which is approximately 18.84 cubic units. So the answer is option B.18.84 cubic units.

Given:

AB is the diameter of a circle.

m∠CAB = 26°

To find:

The measure of m∠CBA.

Solution:

Angle formed in the diameter of a circle is always 90°.

⇒ m∠ACB = 90°

In triangle ACB,

Sum of the angles in the triangle = 180°

m∠CAB + m∠ACB + m∠CBA = 180°

26° + 90° + m∠CBA = 180°

116° + m∠CBA = 180°

Subtract 116° from both sides.

116° + m∠CBA - 116° = 180° - 116°

m∠CBA = 64°

The measure of m∠CBA is 64°.

The size of angle CBA is 128 degrees.

To find the size of CBA, we can use the fact that angles in a triangle add up to 180 degrees. Since AB is a diameter, it divides the circle into two semicircles, and angle CAB is an inscribed angle that is half the measure of the central angle.

Therefore, m(CAB) = 26 degrees, and m(CBO) = 2 * 26 = 52 degrees. Since angle CBA is an exterior angle of triangle CBO, it is equal to the sum of the remote interior angles, which is 180 - 52 = 128 degrees.

So, the size of CBA is 128 degrees. The answer is option D. 74.

Answer:

a) 0.0156

b) 0.4219

c) 0.1406

Step-by-step explanation:

We are given the following information:

We treat adult having type O+ blood as a success.

P(Adult have type O+ blood) = 0.25

Then the number of adults follows a binomial distribution, where

[tex]P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}[/tex]

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 3

a) All three are type O+

[tex]P(x =3)\\= \binom{3}{3}(0.25)^3(1-0.25)^0\\= 0.0156[/tex]

b) None of them is type O+

[tex]P(x =0)\\= \binom{3}{0}(0.25)^0(1-0.25)^3\\= 0.4219[/tex]

c) Two out of the three are type O

[tex]P(x =2)\\= \binom{3}{2}(0.25)^2(1-0.25)^1\\= 0.1406[/tex]

Using the principle of binomial probability, the probability o the required events are :

Recall :

A.) Probability that all 3 are O+ :

x = 3

P(x = 3) = 3C3 × 0.25³ × 1 = 0.0156

B.) Probability that none 3 are O+

x = 0

P(x = 3) = 3C0 × 1 × 0.75³= 0.4219

C.) Probability that 2 out of the three are O+

x = 2

P(x = 2) = 3C2 × 0.25² × 0.75¹ = 0.1406

Therefore, the required probabilities are : 0.0156, 0.4219 and 0.1406 respectively.

An expression for the profit of the company is 26x - 0.0002x^2 - 120,000.

To find the expression for the profit of a company, we need to subtract the cost from the revenue.

The cost of the company is given by the expression 14x + 120,000, where x represents the quantity of the product being produced or sold.

The revenue of the company is given by the expression 40x - 0.0002x^2, where x represents the quantity of the product being produced or sold.

To find the profit, we subtract the cost from the revenue:

Profit = Revenue - Cost

Profit = (40x - 0.0002x^2) - (14x + 120,000)

To simplify the expression, we distribute the negative sign:

Profit = 40x - 0.0002x^2 - 14x - 120,000

Combining like terms:

Profit = (40x - 14x) - 0.0002x^2 - 120,000

Simplifying further:

Profit = 26x - 0.0002x^2 - 120,000

Therefore, an expression for the profit of the company is 26x - 0.0002x^2 - 120,000.

Final answer:

The profit of a company is the difference between its total revenue and costs, and can be calculated using the formula P = R - (14x - 0.0002x²), where P is profit, R is revenue, and x is the number of units.

Explanation:

To calculate the expression for the profit of the company, we need to find the difference between the total revenue and the total cost.

Given the cost can be modeled by 14x - 0.0002x2, and assuming the revenue is R, the profit P can be represented as:

P = R - (14x - 0.0002x²)

If we are given a specific value for the revenue, we would substitute it in place of R to find an explicit expression for P. For instance, if the revenue is $200,000, the profit formula would be:

P = $200,000 - (14x - 0.0002x²)

It's important to note that the profit decreases as the cost increases, and when costs exceed revenue, the company experiences a loss.
