There are 12 teaspoons of vinegar and 30 teaspoons of olive oil in the 42 teaspoons of salad.

2.4)

There are 4 teaspoons of vinegar and 10 teaspoons of olive oil in the 14 teaspoons of salad.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

6 teaspoons of vinegar = 15 teaspoons of olive oil.

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Now,

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 2 on both sides.

2 teaspoons of vinegar = 5 teaspoons of olive oil.

Now,

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 8 on both sides.

8 teaspoons of vinegar = 20 teaspoons of olive oil.

Now,

Total number of teaspoons = 42

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 12 on both sides.

12 teaspoons of vinegar = 30 teaspoons of olive oil.

12 + 30 = 42 teaspoons

Now,

1 teaspoon of vinegar = 5/2 teaspoons of olive oil.

Multiply 4 on both sides.

4 teaspoons of vinegar = 10 teaspoons of olive oil.

4 + 10 = 14 teaspoons

Thus,

2 teaspoons of vinegar are needed for 5 teaspoons of olive oil.

8 teaspoons of vinegar are needed for  20 teaspoons of olive oil.

There are 12 teaspoons of vinegar and 30 teaspoons of olive oil in the 42 teaspoons of salad.

There are 4 teaspoons of vinegar and 10 teaspoons of olive oil in the 14 teaspoons of salad.

Step-by-step explanation:

trust me c is the correct answer

Answer:

To calculate Harry's total bill, we need to consider the cost of labor and the cost of the parts. Let's break it down step by step:

1. Labor cost:

The mechanic charges $24 per hour for labor, and the labor was charged for 1 3/4 hours.

Convert 1 3/4 hours to a mixed fraction: 1 3/4 = (4 + 3)/4 = 7/4 hours.

Labor cost = Labor rate per hour * Labor hours

Labor cost = $24/hour * 7/4 hours

To calculate this, we can multiply the numerators (24 * 7) and the denominators (1 * 4) separately:

Labor cost = ($24 * 7) / (1 * 4)

Labor cost = $168 / 4

Labor cost = $42

2. Cost of parts:

The mechanic replaced the spark plugs for $9, the air filter for $12, and the fuel filter for $4.79.

Cost of parts = Spark plugs cost + Air filter cost + Fuel filter cost

Cost of parts = $9 + $12 + $4.79

Cost of parts = $25.79

3. Total bill:

Total bill = Labor cost + Cost of parts

Total bill = $42 + $25.79

Total bill ≈ $67.79

Therefore, Harry's total bill, including labor and the cost of parts, is approximately $67.79.

Answer:

x=11

Step-by-step explanation:

x=11 because, 6x+8= 74, so you do 74-8=66 and 66/6= 11. so x=11,

the measure of 2 is 7(11)-2+m=106.

so you add 2 on both sides to cancel it out, and you end up with 7(11)+m=108

now you do 7(11)= 77, and you subtract from both sides and get 31.

therefore, m=31.

The polynomial that represents the area of the shaded region is given as follows:

x² - 3x + 36.

The area of a rectangle is given by the multiplication of the width and the length of the triangle, as follows:

A = lw.

For the entire region, the area is given as follows:

A = (x + 1)(x + 1)

A = x² + 2x + 1.

The area of the white region is given as follows:

Aw = 5(x - 7)

Aw = 5x - 35.

Then the area of the shaded region is given as follows:

As = A - Aw

A = x² + 2x + 1 - (5x - 35)

A = x² + 2x + 1 - 5x + 35

A = x² - 3x + 36.

Step-by-step explanation:

The Surface area of the rectangular pyramid is 507 unit². Therefore, Option C is correct.

A right rectangular pyramid is a pyramid, with four slant sides, and a rectagular base, such that all the sides are congruent and the vertex is atop of the midpoint of the base rectangle.

Given:

The Length of the base rectangle = 13 unit

The Width of the  base rectangle = 13 unit

The Height of triangle on the side of pyramid = 13 unit

The Length of the base of the triangle = 13 unit

Now, Surface area of the rectangular pyramid = Area of Base + 4 × Area of triangle on side.

Area of base = length × width = 13 × 13 = 169 unit²

Area of the triangle = 1/2 × base  × height = 1/2 × 13 × 13 = 84.5 unit²

Surface Area = 169 + 4 × 84.5 = 169 +  328 = 507 unit²

Therefore, Option C is correct.

Note that the limit of the expression as x approaches infinity is 1/2.

start by multiplying both the numerator and denominator by the conjugate  expression

√ (x ² - 9x + 1) + x,

this will eliminates the root in the numerator

lim x->∞ [(√(x ² - 9x + 1) - x)  * (√(x² - 9x + 1) + x)] / (√(x² - 9x + 1) + x)

Expanding the numerator

lim x- >∞ [(x² - 9x + 1) - x^2] / (√(x² - 9x + 1) + x)

Simplifying further:

lim x->∞ [(1 - 9/x + 1/ x²)] / (√(1 - 9/x + 1 /x²) + 1)

we can see that the 1/x ² term approaches zero, and the expression simplifies to

lim x->∞ [(1 - 0)]  / (√(1 - 0) + 1)

= 1/2

So it is correct to state that the limit of the expression as x approaches infinity is 1/2.

Option B has a lower monthly payment but a longer loan term and a higher total amount paid over the life of the loan.

What is Simple Interest ?

Simple interest is a type of interest that is calculated based on the initial principal amount of money invested or borrowed, and does not change over time. It is commonly used in simple financial transactions, such as loans or investments with short-term durations.

B. To find the sum of all the payments for Option A, we can simply multiply the monthly payment by the total number of payments (number of years multiplied by 12):

Sum of Payments = Monthly Payment * Total Number of Payments

Sum of Payments = 996.32 * (25*12)

Sum of Payments = $298,896.00

So the sum of all the payments for Option A is $298,896.00.

D. To find the sum of all the payments for Option B, we can use the same formula as for Option A:

Sum of Payments = Monthly Payment * Total Number of Payments

Sum of Payments = 829.80 * (30*12)

Sum of Payments = $298,728.00

So the sum of all the payments for Option B is $298,728.00.

E. To determine which option is the best, we need to consider several factors, such as the total amount paid over the life of the loan, the length of the loan term, and the monthly payment.

Option A has a higher monthly payment but a shorter loan term and a lower total amount paid over the life of the loan.

Therefore, Option B has a lower monthly payment but a longer loan term and a higher total amount paid over the life of the loan.

Answer:

H0: μ = 100 ; H1: μ > 100 ;

Test statistic = 0.75 ;

We fail to reject null ;

Kindly check explanation for the rest

Step-by-step explanation:

Given that :

H0: μ = 100

H1: μ > 100

Sample mean, x = 100.6 ; n = 9 ; sample Standard deviation, s = 2.4

Test statistic :

(x - μ) ÷ s/sqrt(n)

(100.6 - 100) ÷ 2.4 / sqrt(9)

0.6 ÷ 0.8 = 0.75

Probability of not rejecting the null :

P = P(Z > 0.75) = 0.22663

α = 0.05

Since, P > α ; we fail to reject the Null ; there is no sufficient evidence to accept the claim that mean strength is > 100 psi

μ + Zcritical*s/sqrt(n)

Zcritical at (1 - α) = 1.645

100 + 1.645*(2.4/3)

100 + 1.316 = 101.316

(x - μ) ÷ s/sqrt(n)

(101.316 - 102) ÷ 2.4 / sqrt(9)

-0.684 ÷ 0.8 = 0.75

= - 0.855

P(Z < - 0.855) = 0.1963 (Z probability calculator).

95% lower confidence interval :

x - error margin, E

E = Zcritical * s/sqrt(n)

E = 1.645 * 0.8 = 1.316

100.6 - 1.316 = 99.284

From part c :

Interval becomes ;

(99.284, 101.316) ; this interval contains the hypothesized mean value of 100. Hence we fail to reject the null.

The mean and median of the given data is 84 and 84, in order to have 85% as average, Alyssa should score 89 marks and we cannot say anything about how the median is affected.

Part A: Finding the mean of the data,

Mean = (74 + 86 + 94 + 82) / 4 = 336 / 4 = 84

Therefore, the mean score is 84. To find the median, we first need to put the scores in order from smallest to largest, 74, 82, 86, 94. Since we have an even number of scores, the median is the average of the two middle scores. In this case, the two middle scores are 82 and 86, so we take their average,

Median = (82 + 86) / 2 = 168 / 2 = 84

Therefore, the median score is 84.

Part B: Let x be the score Alyssa needs to earn on her fifth test. To find the score she needs to maintain an 85% average, we can set up the following equation,

(74 + 86 + 94 + 82 + x) / 5 = 85

Multiplying both sides by 5, we get,

74 + 86 + 94 + 82 + x = 425

Adding up the first four scores, we get,

74 + 86 + 94 + 82 = 336

Substituting in equation,

336 + x = 425

Subtracting 336 from both sides, we get,

x = 89

Therefore, Alyssa needs to earn at least an 89 on her fifth test to maintain an 85% average.

Part C: The median is the middle score when the data is arranged in order. Since the fifth test score has not yet been added, the median is still 84. So, we cannot really say anything about the median.
