Answer:

A=80 pounds, B=63 pounds

Step-by-step explanation:

Cost of type A=$4.35 per pound

Cost of type B=$5.80 per pound

Cost of A+ B=$713.40

A+B=143 pounds

A=143-B

QaPa+QbPb=713.40

A*4.35 + B*5.80=713.40

4.35A+5.80B=713.40

Substitute A=143-B

4.35(143-B) + 5.80B=713.40

622.05 - 4.35B + 5.80B=713.40

1.45B=713.40-622.05

1.45B=91.35

B=91.35/1.45

=63

B=63

Recall,

A+B=143

A+63=143

A=143-63

=80

A=80 pounds, B=63 pounds

Answer:

644.89

Step-by-step explanation:

Answer:

644.89 m

Step-by-step explanation:

68 / 100 * 948.37 = 0.68 * 948.37 = 644.89 m (2 d.p.)

Answer:

$0.50

Step-by-step explanation:

Total cost before tax = Cost of oranges + Cost of juice bottles

$12.6 = $2.66 + Cost of juice bottles

Cost of juice bottles = $12.6 - $2.66 = $9.94

There are 20 juice bottles in the pack, so to find the cost of each bottle, we divide the total cost of the juice bottles by the number of bottles:

Cost of each juice bottle = Cost of juice bottles / Number of juice bottles

Cost of each juice bottle = $9.94 / 20

Cost of each juice bottle = $0.497

Therefore, the cost of each juice bottle was $0.497, or approximately $0.50, before tax.

The given function f, with the provided set of ordered pairs, has a domain of {10, 17, 45, 51} and a range of {-6, 1, 5}.

The domain of a function refers to the set of all possible input values or x-values for which the function is defined. In this case, the given set of ordered pairs determines the domain. Looking at the x-values in the set {10, 17, 45, 51}, these are the unique inputs for which the function f is defined. Hence, the domain of f is {10, 17, 45, 51}.
On the other hand, the range of a function refers to the set of all possible output values or y-values that the function can take. By examining the y-values in the set {-6, 1, 5}, we can observe the distinct outputs generated by the function f. Thus, the range of f is {-6, 1, 5}.
In summary, the domain of the function f is {10, 17, 45, 51}, and the range of f is {-6, 1, 5}.

Step-by-step explanation:

The standard deviation of hole diameter is less than or equal to 0.01 millimeter.

The given hypothesis test is on the standard deviation of hole diameter. To check if there is strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeter or not, we can use the Chi-Square distribution.

The null hypothesis, H0, is the claim that the standard deviation is less than or equal to 0.01 millimeter. The alternative hypothesis, Ha, is the claim that the standard deviation is greater than 0.01 millimeter. We can use the following formula to calculate the chi-square statistic:

\(\chi^2 = (n - 1) \times s^2 / \sigma_0^2\)

where, n is sample size, s is sample standard deviation, σ0 is hypothesized standard deviation. The chi-square statistic is calculated as follows:

\(\chi^2 = (15 - 1) \times 0.008^2 / 0.01^2\)

= 1.44

The critical value of the Chi-Square distribution for α = 0.10 with 14 degrees of freedom is 22.362.So, we have:

χ2 < 22.362 (Reject the alternative hypothesis)

Thus, we reject the alternative hypothesis. There is no strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeter. Therefore, we can conclude that the standard deviation of hole diameter is less than or equal to 0.01 millimeter.

Answer:

Answer:

Weight of each large box: 18.25kg

Weight of each small box: 13.25kg

Step-by-step explanation:

For this question, we have two unknowns, but we can solve them as we are given two equations.

If we use the variables 'L' for Large and 'S' for small, we  an write out the information given to us as equations:

3L + 5S = 121

6L + 2S = 136

Now we can solve these simultaneous equations by multiplying one of them by a constant so that one of the variable co-efficients are the same so we can cancel them. We can see here that we can easily double the first equation which would result in both having 6L:

2(3L + 5S) = 2(121)

=> 6L+10S=242

Now that we have one term which is the same, we can subtract one equation from the other:

  6L+ 10S = 242

- (6L + 2S = 136)

------------------------

=>0L + 8S = 106

Now we can solve for S:

8S/8 = 106/8

S = 13.25

And use this value of S to solve for L:

3L + 5(13.25) = 121

3L + 66.25 = 121

3L + 66.25 - 66.25 = 121 - 66.25

3L = 54.75

3L/3 = 54.75/3

L = 18.25

The percent of increase in motorcycle production is approximately 9.75%, and the percent of decrease in Sarah Walker's long-distance phone bills is approximately 42.07%.

To find the percent increase in motorcycle production, we use the formula:

Percent Increase = (New Value - Old Value)/Old Value x 100%

Plugging in the given values, we get:

Percent Increase = (318000 - 291500)/291500 x 100% = 9.75%

Therefore, the percent of increase in motorcycle production is approximately 9.75%.

To find the percent decrease in Sarah Walker's phone bills, we use the formula:

Percent Decrease = (Old Value - New Value)/Old Value x 100%

Plugging in the given values, we get:

Percent Decrease = (40.10 - 22.90)/40.10 x 100% = 42.07%

Therefore, the percent of decrease in Sarah Walker's long-distance phone bills is approximately 42.07%.

D. 3

Step-by-step explanation:

The slopes of parallel lines are the same.

We have derived the equation β = cv = 1 - (E₀ + KE₀)².

To derive the equation β = cv = 1 - (E₀ + KE₀)², we can begin with the given equations:

E² = p²c² + E₀²

K + E = ε₀ = 1 - β²

E = p²c² + E₀ = p²c² + mc²

K = E - E₀ = 1 - ρ²E₀² - E₀

We'll rearrange these equations to arrive at the desired equation.

Starting with equation 1, we have:

E² = p²c² + E₀²

From equation 3, we substitute E = p²c² + mc²:

(p²c² + mc²)² = p²c² + E₀²

Expanding and simplifying:

p⁴c⁴ + 2p²mc⁴ + m²c⁴ = p²c² + E₀²

Next, we focus on equation 4:

K = E - E₀ = 1 - ρ²E₀² - E₀

Substituting equation 1 into equation 4:

K = p²c² + E₀² - E₀ = 1 - ρ²E₀² - E₀

Now, we substitute equation 2 into equation 4:

K = 1 - β² - E₀

Substituting this value of K into our modified equation 4:

1 - β² - E₀ = p²c² + E₀² - E₀

Rearranging and simplifying:

β² = 1 - (E₀ + K E₀)²

Thus, we have derived the equation β = cv = 1 - (E₀ + KE₀)².

Answer:

f = 1.1 Hz

Step-by-step explanation:

Given that,

The velocity of an ocean wave, v = 4.4 m/s

The distance  between the crest of each wave is 4 m.

We need to find the frequency of the waves.

The distance between the crest of a wave is called the wavelength of a wave.

The relation between the frequency, wavelength and the velocity of a wave is given by :

\(v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{4.4}{4}\\\\f=1.1\ Hz\)

So, the frequency of the waves is 1.1 Hz.

First turn any mixed numbers into improper fractions. 1 3/4 would be 7/4. Becuase you multiply the whole number by the denominator and then add the numerator.

So now you have 7/4 divided by 2/5. Whenever you divide, you flip the 2nd fraction upside down... known as the reciprocal. And after that you multiply the first number by the upside down 2nd number.

So now you have 7/4 X 5/2. When multiplying, just multiply the numerators across and the denominators across. As your answer, you get 35/8 or 4 3/8.

The quotient obtained by dividing two given fractions is 25/12.

The given fractions are \(1\frac{2}{3}\) and 4/5.

In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Here, the mixed fraction \(1\frac{2}{3}\) can be written as 5/3.

Now, 5/3 ÷ 4/5

= 5/3 × 5/4

= 25/12

Hence, the quotient obtained by dividing two given fractions is 25/12.

Answer:

-(cos α)/(sin α)

Step-by-step explanation:

use trigonometric identities

∠g and ∠h are complementary angles and ∠g and ∠h are acute angles are true statements from the given information

Two angles are given.

∠g = (2x-90)°

∠h = (180-2x)°

We have to find the statement which is true about the angles g and h.

If both angles are greater than zero.

Complementary angles add up to 90 degrees

i.e., ∠g and ∠h are complementary if ∠g + ∠h = 90°.

Substituting the given values:

∠g + ∠h

= (2x-90)° + (180-2x)° = 90°

Thus, ∠g and ∠h are complementary angles.

and both the angles are less than 90 degrees so we can tell that angles ∠g and ∠h  are acute.

So the statement ∠g and ∠h are acute angles is also true

Hence, ∠g and ∠h are complementary angles and ∠g and ∠h are acute angles are true statements

(a) The exponential equation that can be used to model the population of the chicken farm t years after 2023 is:

P(t) = 2850 x 1.03 in power t

where P(t) is the population of the chicken farm after t years.

(b) To estimate the population of the chicken farm in 2045, we need to find P(22), as 2045 - 2023 = 22.

P(22) = 2850 x 1.03²²

= 4405.56 (rounded to the nearest chicken)

Therefore, the estimated population of the chicken farm in 2045 is 4406.
