Hello there!

∆ABC and ∆XYZ are simular so:

[tex] \displaystyle \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} \\ \\ \frac{2}{10} = \frac{5}{25} = \frac{AC}{20} \\ \\ \frac{1}{5} = \frac{1}{5} = \frac{AC}{20} \\ \\ \frac{AC}{20} = \frac{1}{5} \\ \\ AC = \frac{20 \times 1}{5} = 4[/tex]

Answer: 4

Answer:

4

Step-by-step explanation:

We have to find length of AC in ΔABC

Since ΔABC is similar to ΔXYZ, the corresponding sides of ΔABC to the corresponding sides of ΔXYZ should be of similar ratio

Equivalently stated

[tex]\dfrac{AB}{XY} = \dfrac{BC}{YZ} = \dfrac{AC}{XZ}[/tex]

Plugging in known values we get

[tex]\dfrac{AB}{XY} = \dfrac{2}{10} = \dfrac{1}{5}\\\\\dfrac{BC}{YZ} = \dfrac{5}{25} = \dfrac{1}{5}\\[/tex]

Thus we see that the length of each side of ΔABC is one-fifth the length of each corresponding side of ΔXYZ.

So

[tex]AC =\dfrac{1}{5} XZ = \dfrac{1}{5} \cdot 20 = 4[/tex]

The ratio of carp to salmon for each lake is given as follows:

Then the ascending order on the proportion of fish that are salmon is given as follows:

Lake b, Lake c, Lake c.

The ratio of an amount A over an amount B is obtained applying the proportion of these amounts, that is, the division of A by B.

The ratios of carp to salmon, in the form 1:n, are obtained considering that n is the division of the number of salmon by the number of carp, hence:

The higher rates of salmon have the higher values of n, thus the ascending order of the proportion of fish that are salmon is given as follows:

Lake b, Lake c, Lake c.

Doesn't make sense but with the information given. To find the percentage of glass beads on the necklace, you need to divide the number of glass beads by the total number of beads and multiply by 100.

You can use the formula:

percent = (number of glass beads / total number of beads) x 100

In this case:

percent = (75 / 150) x 100 = 0.5 x 100 = 50

So, 50% of the beads on the necklace are glass.

The average pace of Malik is 0.182 mile per minute.

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Given that,

Distance Malik rode on a trail = 10 miles

Malik biked a new trail in a total of 57.5 minutes.

But he took 2.5 minutes as water break.

Total time Malik took to cover the distance = 57.5 minutes - 2.5 minutes

                                                                        = 55 minutes

We have to calculate the average pace of Malik which is actually the speed.

Speed = Distance / Time

           = 10 miles / 55 minutes

           = 0.182 mile per minute

Hence Malik rides in an average pace of 0.182 mile per minute.

The area of the floor of a square room in square meter whose each side is 800 cm is 640000 cm ^ 2.

The area of a square or square shaped figures is:

area = side x side or (side) ^2

The length of the side of the floor of the given square room is:

800 cm

Therefore, area of the floor of the given square room is:

800 cm x 800 cm = 640000 cm ^ 2.

Thus, the area of the floor of the given square room in square meter whose each side is 800 cm is 640000 cm ^ 2.

= 52º

Now, since JKM is the total of all angle measurements, then we can say that;

The monthly payment with given simple interest will be $673.

What is simple interest?

Simple Interest is an easy method of calculating the interest for a loan/principal amount. Simple interest is a concept that is used in many sectors such as banking, finance, automobile, and so on. When you make a payment for a loan, first it goes to the monthly interest and the remaining goes towards the principal amount.

Simple interest formula is given as:

SI=P*R*T/100

Where SI = simple interest

P = principal

R = interest rate (in percentage)

T = time duration (in years)

In order to calculate the total amount, the following formula is used:

Amount (A) = Principal (P) + Simple Interest (SI)

Now,

Amount to Borrow=$28716

Rate=3.12%

Time=4 years

SI=28716*3.12*4/100

=$3584

Total amount to pay=28716+3584

=$32300

Hence,

        monthly payment for 4 years =32300/48

  monthly payment=$673

Answer:

IF tan(theta) = -8/7 = opposite side/adjacent side, then that means that sin(theta) = -8/(sqr(64+49) = -8/sqr113 = about -0.7526

Step-by-step explanation:

the tangents are negative in the quadrant II or IV

and sines are negative in the quadrant III or IV

so i think that this angle is in quadrant IV to satisfy for the of the both requirements.

but angle 0 seems to try and mean something other than 0 degrees or 0 radians. so It probably just means theta, which is a 0 probably with a line through it

IF tan(theta) = -8/7 = opposite side/adjacent side, then sin(theta) = -8/(sqr(64+49) = -8/sqr113 = about -0.7526

The situation regarding the experimental probability is described as follows:

The probability that she makes a shot is of 62.5% = 5/8. Use whole numbers from 1 to 8, with 1-5 representing shots that she makes, and 6-8 representing the shots that she misses. For each trial, generate 10 random numbers. Count the number of trials in which the numbers 1 - 5 appears 3 or more times. Divide the number of trials in which she made at least 3 shots by the total number of trials.

A probability is calculated as the division of the number of desired outcomes by the number of total outcomes.

The theoretical probability of making a shot in this problem is given as follows:

62.5%.

Answer:

23

Step-by-step explanation:

Given Information:

If we have to evaluate f(-2), we can consider that f(x) = f(-2) = 6x²- 2x - 5.

Now, we can substitute the solution into the quadratic equation and simplify it to its simplest possible form using the solution (x = -2).

Therefore, the evaluated form for f(-2) is 23.

To tell if a log graph is a growth or decaying, look at the slope of the line. If the slope is positive, then it is growth; if the slope is negative, then it is decay.

A positive slope indicates that the value is increasing over time, while a negative slope indicates that the value is decreasing over time. To find the slope, take two points on the line and calculate the change in the y-value divided by the change in the x-value.

If the answer is positive, the graph is growth; if the answer is negative, the graph is decay. Additionally, you can look at the y-intercept of the graph, which is the value where the line meets the y-axis. If the y-intercept is positive, the graph is growth; if the y-intercept is negative, the graph is decay.

x - 15x/100 = $42 {simply the left hand expression to a single fraction}

(100x - 15x)/100 = $42 {simply the terms in the bracket}

$85x/100 = $42

$85x = $4200 {cross multiplication}
