Answer:

36 ft

Step-by-step explanation:

So the proportion of the big triangle is 48:4 or 12:1. So if the small triangle’s height is 3 feet, then 3*12 is 36 feet.

Answer: 36 ft

Step-by-step explanation:

Similar triangles means there is a constant proportion between the left legs, the base legs, and the hypotenuses.

$\frac{LeftLeg(large)}{LeftLeg(small)}= \frac{BaseLeg(large)}{BaseLeg(small)}$

$\frac{x}{3}= \frac{48}{4}$

Cross multiply: x(4) = 3(48)

solve for x: ÷4 ÷4

x = 3(12)

= 36

<h3>What is expressions ?</h3>

In most cases, the two expressions that are comparable to one another for the total cost of the cloth are

(7.99 × 7/3) and 18.64

Total cost = Cost of fabric per yard * Number of fabrics

= 7.99 × 2 1/3

= (7.99 × 7/3)

= 55.93 / 3

= 18.64

As a result, the two expressions that are comparable to one another for the total cost of the cloth are and

Step-by-step explanation:

*Note:

The definition of a derivative is the slope of the tangent line.

Step 1: Define

Identify.

f(-2.4) = -1

f(-1.9) = -8

Step 2: Differentiate

Simply plug in the 2 coordinates into the slope formula to find slope m.

[Derivative] Set up [Slope Formula]: $\displaystyle f'(-2.4) \approx \frac{f(x_2) - f(x_1)}{x_2 - x_1}$
Substitute in coordinates: $\displaystyle f'(-2.4) \approx \frac{-8 - -1}{-1.9 - -2.4}$
Evaluate: $\displaystyle f'(-2.4) \approx -14$

A consumer survey conducted in two consecutive years determined that a fixed baskets of goods and services cost $95.00 in year 1

Gnesinka [82]

Answer:

1.315%

Step-by-step explanation:

Given:

Prices:

Year 1 =old price =$95

Year 2 = new price = $96.25

The inflation rate is the difference in price between two Given period :

Inflation rate :

(Change in price / old price) * 100%

((New price - old price) / old price) * 100%

((96.25 - 95) / 96) * 100%

= (1.25 / 95) * 100%

= 0.0131578 * 100%

= 1.315%

Question 18 Item 18 The distribution of the number of moths captured per night by a certain moth trap is approximately normal wi

juin [17]

Answer:

Standard deviation 46.3

Step-by-step explanation:

A 28% of the distribution is equivalent to a z score of -0.5828, you can use a z table to find that.

Z score is calculated as follows:

$z = \frac{x-\mu}{\sigma}$

x is the number being evaluated

μ is the mean

σ is the standard deviation

And it is used to calculate how many standard deviations you are from the mean of the sample.

Replacing with the known information you can calculate the standard deviation:

$\sigma=\frac{x-\mu}{z} =\frac{76-103}{-0.5828}= 46.3$
