Answer:

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 mantissa of scientific notation is between 1 and 10 in absolute value, or 1 ≤ |a| < 10.  It can be 1, hence, it does not have to be greater than 1.

A scientific notation has the form:

a x 10ᵇ

Where b is an integer and is called exponent.

a is a real number between 1 and 10 (in absolute value), it includes 1 but not 10, or we can write a should satisfy 1 ≤ |a| < 10.

Usually, a is called mantissa.

Example:

2567 can be written in scientific notation as:

2567 = 2.567 x 10³

0.0045 can be written in scientific notation as:

0.0045  = 4.5 x 10⁻³

250 x 10² can be written in scientific notation as:

250 x 10² = 2.5 x 10⁴

The polynomial 3x³ 2x² +3 can be written as 3x³ + 2x² + 3. In order to get the polynomial 3x² + 4, we need to add a polynomial which is equal to -3x³ + 5x² + 1.

Therefore, the correct answer is (3) - 3x3 + 5x2 +1.

We can confirm this by performing the following calculation:

3x³ + 2x² + 3 + (-3x³ + 5x² + 1) = 3x² + 4

3x³ + (-3x³) = 0

2x² + 5x² = 7x²

3 + 1 = 4

Therefore, 0 + 7x² + 4 = 3x² + 4, which confirms that the correct answer is  3x3 + 5x2 +1.

3x3 + 5x2 +1 is the polynomial should be added in 3x³ 2x² +3 to get the polynomial 3x² +4.

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]

Step-by-step explanation:

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%.

The equivalent fraction is given as follows:

5/8.

Hence, to obtain the experimental probability, we need to design an experiment for which there are eight possibilites, with five of them composing a success and three of them composing a failure.

Answer:

Step-by-step explanation:

y = x + 8

x + y = 2

using substitution, since y is equal to x + 8 we substitute it for the y in x + y = 2

so we get: x + (x+8) =2

then we simplify, getting 2x + 8 = 2

We make the x on its own on one side of the equation by subtracting 8 on both sides.

2x = -6

divide

x = -3

y = 5

(if x = -3, y = 5 because -3 + 8 =5)

test answer

5 = -3 + 8 works and -3 + 5 = 2 works as well

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 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 paragraph proof is a proof written in the form of a paragraph. In other words, it is a logical argument written as a paragraph, giving evidence and details to arrive at a conclusion.

Paragraph proofs are comprehensive paragraphs that explain the process of each proof. Like two-column proofs, they have multiple steps and justifications. But instead of columns, the given information is formatted like a word problem — written out in long-hand format.

Since vertical angles are congruent, it is known that angle DCB is congruent to angle ACE. It can now be concluded that triangle DCB is congruent to triangle ACE according to the Side-Angle-Side (SAS) theorem.

There are two different types of proofs: informal and formal. Formal proof is often introduced using a two-column format, as favored by many geometry teachers.
