Answer:

≈ 3.9 miles

Step-by-step explanation:

The third angle in the triangle is

180° - (53 + 78)° = 180° - 131° = 49°

Using the Sine rule in the triangle with distance from 2 being x, then

\(\frac{3}{sin49}\) = \(\frac{x}{sin78}\) ( cross- multiply )

x × sin49° = 3 × sin78° ( divide both sides by sin49° )

x = \(\frac{3sin78}{sin49}\) ≈ 3.9 ( to the nearest tenth )

A nuclear equation is an equation in which a nucleus of a larger atom breaks into smaller nuclei or the smaller nuclei combine to form a larger nucleus. The former is known as the fission reaction and the latter is the fusion reaction.

In these reactions as well the law of conversation of mass is upheld thus the sum of the atomic mass and the sum of the atomic number is constant

Atomic mass in reactant = 144

Atomic mass in product = 4 + x

144 = 4 + x

x = 144 - 4 = 140

Atomic number in reactant = 60

Atomic mass in product = 2 + x

60 = 2 + x

x = 60 - 2 = 58

Thus, ¹⁴⁴Nd₆₀ ----> ⁴He₂ + ¹⁴⁰Ce₅₈

Step-by-step explanation:

a. h(f(2))The given functions are

f(t) = 1² - t and h(x) = 3x + 2

To evaluate h(f(2)), first we need to find the value of f(2) and then use it in h(x).Therefore,

f(2) = 1² - 2 = -1

Now, using f(2) in h(x)h(f(2)) = h(-1) = 3(-1) + 2= -3 + 2= -1

Therefore, h(f(2)) = -1b. h(f(-2))To evaluate h(f(-2)), first we need to find the value of f(-2) and then use it in h(x).Therefore,f(-2) = 1² - (-2) = 3

Now, using f(-2) in h(x)h(f(-2)) = h(3) = 3(3) + 2= 9 + 2= 11

Therefore, h(f(-2)) = 11Therefore, the answers are:a. h(f(2)) = -1b. h(f(-2)) = 11Long answer:Given functions:

f(t) = 1² - t and h(x) = 3x + 2

To evaluate h(f(2)), we need to find the value of f(2) first and then use it in h(x).Therefore,f(2) = 1² - 2 = -1Now, using f(2) in h(x)h(f(2)) = h(-1) = 3(-1) + 2= -3 + 2= -1

Therefore, h(f(2)) = -1Similarly, to evaluate h(f(-2)), we need to find the value of f(-2) first and then use it in h(x).Therefore,f(-2) = 1² - (-2) = 3

Now, using f(-2) in h(x)h(f(-2)) = h(3) = 3(3) + 2= 9 + 2= 11

Therefore, h(f(-2)) = 11Therefore, the answers are:a. h(f(2)) = -1b. h(f(-2)) = 11.

The total amount of money Lee would have at the end of 8 years is $7,600.

Simple interest is interest that is earned only on the amount of money deposited. In order to determine the amount of money Lee would have at the ned of 8 years, it would be the sum of simple interest earned and the amount deposited,

Simple interest = principal x time x interest rate

$5000 + 0.065 x 8 = $2,600

Total sum of money = $2,600 + 5000 = $7,600

Step-by-step explanation:

To determine the number of milligrams in 1.5 teaspoons of medication, we need to convert the volume from teaspoons to milliliters and then use the given concentration.

First, we need to know the conversion factor for teaspoons to milliliters. A common conversion is that 1 teaspoon is approximately equal to 4.93 milliliters.

Now, we can calculate the volume of 1.5 teaspoons in milliliters:

1.5 teaspoons * 4.93 mL/teaspoon = 7.395 mL

Next, we can use the concentration of the medication to find the number of milligrams in the given volume. The concentration is 125 mg/5 mL, which means that in 5 mL of the medication, there are 125 mg.

To find the number of milligrams in 7.395 mL, we can set up a proportion:

125 mg / 5 mL = x mg / 7.395 mL

Cross-multiplying and solving for x, we get:

x = (125 mg * 7.395 mL) / 5 mL = 183.975 mg

Therefore, there are approximately 183.975 mg in 1.5 teaspoons of the medication. Rounding to one decimal place, the closest option provided is 187.5 mg.

Work Shown:

(160 with blue eyes)/(500 total) = (x with blue eyes)/(2500 total)

160/500 = x/2500

x = 2500*(160/500)

x = 800

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

Another approach:

160/500 = 0.32 = 32% of the first group has blue eyes

Assuming this percentage is the same for any group, then,

32% of 2500 = 0.32*2500 = 800 people of the second group are estimated to have blue eyes, of the 2500 total.

All the angles in a triangle add up to 180 degrees.

40 + x + (5x + 14) = 180

54 + 6x = 180

6x = 126

x = 21 degrees

Answer:

x=21

Step-by-step explanation:

a triangle adds up to 180 degree so to find x we will use the formula

(5x+14)+x+40=180

subtract 40 from each side so we have

(5x+14)+x=140

we have 2 terms with the same factor (x) so combine like terms

6x+14=140

subtract 14 from both sides

6x=126

divide both sides by 6

x=21

check your answer

5(21)+14

105+14=119

119+ 21+40=180

so x is equal to 21

If 64 is a perfect cube the length of each edge of the block can be found. The edge length of a cube is: 4cm.

Given:

Volume of cube=64cm³

If 1 > 0, then the linear function of time e(yt) = 0 + 1t displays an upward trend.

In the given linear function of time e(yt) = 0 + 1t, the coefficient of the time variable (t) is positive (1), and it is stated that 1 > 0. This indicates that as time increases, the value of yt also increases. This pattern signifies an upward trend.

An exponential trend would require an exponential function with a positive exponent, which is not the case here. Similarly, a downward trend would require a negative coefficient for time, which is also not the case. A quadratic trend would involve a time variable raised to the power of 2, but the given function is a simple linear function with only a first-degree time variable.

Hence, based on the condition that 1 > 0, the linear function of time e(yt) = 0 + 1t displays an upward trend.
