Find the value of x

False, the given two proportions are not equal.

In this section, the terms ratio and percentage are defined. Both ideas play a significant role in mathematics. Many examples where the notion of the ratio is highlighted may be found in daily life, such as the rate of speed (distance/time) or price (rupees/meter) of a substance.

An equation known as proportion shows that the two ratios presented are equal to one another.

The two given proportions are:

100/210 = 290/340

Simplifying the two we have:

100/210 = 10/21

290/340 = 29/34

We see that the simplified form of the two proportions are different.

In a right triangle, the tangent of an acute angle is the ratio of the length of the opposite side to the length of the adjacent side, the sine of an acute angle is the ratio of the length of the opposite side to the length of the hypotenuse, and the cosine of an acute angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

Using the side lengths given in the problem, we can identify that angle B is the acute angle opposite the side with length 5.

So, we have:

tanB = opposite/adjacent = 12/5

sinB = opposite/hypotenuse = 12/13

cosB = adjacent/hypotenuse = 5/13

Therefore, the values of the trigonometric functions for angle B in this right triangle are:

tanB = 12/5

sinB = 12/13

cosB = 5/13

The percentage did the total yield, by weight, of her fruit harvest declined by approximately 24%, which is option B.

what is percentage ?

Percentage is a way of expressing a number or quantity as a fraction of 100. It is often denoted by the symbol % (percent). For example, 50% means 50 out of 100, or 50/100, or the equivalent fraction 1/2.
Percentages are commonly used in many real-world situations, such as in finance, statistics, and everyday life. They are often used to express changes, differences, or ratios between two values.

According to the question:

To solve this problem, we need to calculate the total weight of fruit harvested in the first year and the total weight of fruit harvested in the second year, and then calculate the percentage decline.

Total weight of fruit harvested in the first year = 40 + 12 = 52 pounds

After a 25% decline, the weight of pears in the second year = 40 - 0.25(40) = 30 pounds

After a 20% decline, the weight of plums in the second year = 12 - 0.20(12) = 9.6 pounds

Total weight of fruit harvested in the second year = 30 + 9.6 = 39.6 pounds

Percentage decline in the total yield of fruit harvest = [(52 - 39.6)/52] x 100% = 23.8%

Therefore, the answer is approximately 24%, which is option B.

Step-by-step explanation:

Let's assume that the customer ordered x burrito bowls.

The cost of x burrito bowls at $6.50 each is 6.50x.

The cost of the plate of corn tacos is $12.96.

The total cost of the order is $32.46.

So we can set up the equation:

6.50x + 12.96 = 32.46

Subtracting 12.96 from both sides, we get:

6.50x = 19.50

Dividing both sides by 6.50, we get:

x = 3

Therefore, the customer ordered 3 burrito bowls.

The length of the third side is 9.

A right-angled triangle is a triangle in which one of its angles is a right angle, meaning it measures exactly 90 degrees (π/2 radians). The other two angles are acute angles, meaning they measure less than 90 degrees.

In a right-angled triangle, the side opposite the right angle is called the hypotenuse. The other two sides are called the legs. The leg opposite to an acute angle is called the opposite side, and the leg adjacent to that angle is called the adjacent side.

The Pythagorean theorem is a fundamental concept in right-angled triangles. It states that the sum of the squares of the lengths of the legs of a right-angled triangle is equal to the square of the length of its hypotenuse. This theorem is often used to calculate the length of one side of a right-angled triangle when the lengths of the other two sides are known.

Let's call the missing side of the right triangle "x". We can use the Pythagorean theorem to solve for x, which states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

So, we have:

x² + 7² = (√130)²

Simplifying:

x² + 49 = 130

x² = 81

Taking the square root of both sides, we get:

x = 9

Therefore, the length of the third side is 9.

What is the interest rate?

The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate. The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.

The formula of monthly payment is

P = [tex]\frac{r (PV)}{1-(1-r)^{-n}}[/tex]

r is the rate of interest.

PV is the present value

n is the number of terms.

The bank offers you an installment loan with an interest rate of 17% over a 60-month term. The cost of the car is $10,000.

PV = $10,000

Answer:

55 KG

Step-by-step explanation:

To convert pounds to kilograms, we can use the conversion factor 1 kg = 2.2 lbs.So,121 lbs = (121 lbs) * (1 kg/2.2 lbs)Simplifying the expression, we have121 lbs ≈ 55.0 kgRounding to the nearest tenth, we get the final answer:121 lbs ≈ 55.0 kg

Answer:

To convert 121 pounds into kilograms, we can use the conversion factor:

1 kg = 2.2 lb

Dividing both sides of this equation by 2.2, we get:

1 lb = 0.454545 kg (rounded to the nearest tenth, this is 0.5 kg)

Therefore, we can convert 121 pounds to kilograms by multiplying by 0.454545:

121 lb * 0.454545 kg/lb = 54.884545 kg

Rounding this to the nearest tenth gives:

54.9 kg

Therefore, 121 pounds is approximately equal to 54.9 kilograms when rounded to the nearest tenth.

The scale of measurement used by the researcher is interval scale as the data is continuous and there are equal intervals between the values.

Mean = (1+2+4+5+7+11)/6 = 5

Median = (4+5)/2 = 4.5

Mode = There is no mode in the data set as none of the numbers are repeated.

Range = maximum value - minimum value = 11 - 1 = 10

Sample Variance = ((1-5)^2 + (2-5)^2 + (4-5)^2 + (5-5)^2 + (7-5)^2 + (11-5)^2)/(6-1) = 14.67

Standard Deviation = sqrt(sample variance) = sqrt(14.67) = 3.83

Mean + 2SD = 5 + 2*3.83 = 12.66, rounded to the nearest integer = 13.

According to the Empirical Rule, 68% of the sample lies within 1 standard deviation of the mean. Therefore, we need to find the values that are 1 standard deviation away from the mean:

Lower limit = Mean - SD = 5 - 3.83 = 1.17, rounded to the nearest integer = 1.

Upper limit = Mean + SD = 5 + 3.83 = 8.83, rounded to the nearest integer = 9.

The clerk did not give Mary any change, so that is the correct response.

A price decrease from the normal or list amount or a proportional deduction from such a debt account, typically applied in exchange for on-time or cash payments.

The total cost of the shirt and three skirts before the coupon is:

$22.65 + 3($33.31) = $122.58

With the 10% discount, the total cost becomes:

$122.58 - 0.1($122.58) = $110.32

To find out how much change the cashier gave back to Mary, we need to subtract the total cost from the amount of money Mary's mom gave her:

$100.00 - $110.32 = -$10.32

Since the result is negative, it means Mary did not have enough money to pay for her purchases and would have to give the cashier an additional $10.32 to cover the full cost of her shopping.

To generate an income of $50,000 per year forever, we need to create a retirement fund that can generate this income through interest and not deplete the principal amount.

We can use the following formula to calculate the required balance in the retirement fund:

Balance = Annual income / Annual interest rate

The annual income we need is $50,000, and the annual interest rate is 7%, so we can calculate the required balance as:

Balance = $50,000 / 0.07

= $714,285.71

Answer:

Step-by-step explanation:

We can use the formula:

average speed = (speed downstream + speed upstream) / 2

We are given the speed downstream is 8 miles per hour and the speed upstream is 2 miles per hour. Therefore,

average speed = (8 + 2) / 2 = 5 miles per hour

So the answer is (B) 5.0 miles per hour to the nearest tenth.
