Answers

1. The longest pencil is 8 inches and the shortest pencil is 2 inches. Therefore, the difference between the length of the longest pencil and the shortest pencil is 8 - 2 = 6 inches.

2. Pencils measuring less than 5 inches: 3 + 2 + 3 = 8 inches in total.

3. False. To determine if more than half of the pencils are 6 inches or shorter, we need to find the total number of pencils and calculate how many of them are 6 inches or shorter.

Total number of pencils = 4 + 3 + 2 + 3 + 7 + 8 = 27

Number of pencils that are 6 inches or shorter = 4 + 3 + 2 + 3 = 12

To find out if more than half of the pencils are 6 inches or shorter, we need to divide the number of pencils that are 6 inches or shorter by the total number of pencils and multiply by 100%:

12/27 x 100% = 44.44%

Since 44.44% is less than 50%, the statement is false.

4. There are three pencils that measure more than 5.5 inches but less than 7.5 inches: 6, 6, and 7. Therefore, the answer is 3 pencils.

How can I find the cube root of 64?

Answers

Answer:

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Step-by-step explanation:

QUESTION 7:

We are trying to find angles 1 and 2.

Known angle: 107˚.

In this question, we have 2 parallel lines with a transversal. A transversal is a line that passes through 2 parallel lines making it so that the angles on both sides are exactly the same.

Step 1: Find the measures of all the angles using the one we already know.

I will start with the angle adjacent (right next to) the angle that measures 107˚. As you can see, it is a supplementary angle because both of them form a straight line, or 180˚.

Therefore,

107+x= 180

x= 180-107

x= 73˚

Next, I will find the measure of the angle that is vertical to the one that measures 107˚. Note that angles that are vertical to each other are always identical, or in other words they have the same measure. Hence, the angle "vertical", or opposite to the one that measures 107˚ has to measure 107˚ as well. You can also tell this is true because they look the same.

Now I'll find the measure of the angle vertical to the one that measures 73˚. As we know, vertical angles are identical, so the one vertical to it is 73˚.

Here, I'll solve for angles 1 and 2. Like I said earlier, when a transversal crosses through 2 parallel lines, there will be 2 sets of angles that all have the same measurements.

To solve for angle 1, simply know what angle is right below it, and that is the one that measures 107˚. (If you look at the 2 lines, you will see that both angle sets are essentially duplicates of each other.) Likewise, angle 2 has to be 73˚ because the one under it is also 73˚.

Angle 1: 107˚

Angle 2: 73˚

QUESTION 8:

Again, we have a transversal that passes through 2 parallel lines. One angle measures 95˚. When there are 3 seperate angles along a straight line, the one next to the one with the given measurement will be the same as that one.

So angle 3 is 95˚. To find angle 4, find the angle measurement that's vertical to angle 3, which is 95˚. Now, since that angle and angle 4 are supplementary (both form a straight line which is always 180˚), 95+x= 180.

(x stands for angle 4)

x+95= 180

x= 180-95

x= 85

Angle 4= 85˚.

QUESTION 9:

ANGLE 5: 49˚

When there is a transversal, there are 2 identical pairs of angles. Therefore, angle 5 must be 49˚.

ANGLE 6: 131˚

angle 5 and angle 6 form a straight line which means they are supplementary angles. Therefore, both angles must add up to 180˚. So 49+x= 180

x= 180-49= 131

(x stands for angle 6)

Practice problems if it helps :) : https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-geometry/cc-8th-angles-between-lines/e/parallel_lines_1

You can find 1 becuase it is the same angle as the one below it, so 1 is 107 degrees and 3 is 73 degrees becuase one line is 180 degrees and 1 and 2 together make a line so I just subtracted 107 from 180

The instructions are: find the tangents of the acute angles in the right triangles. Write each answer as a fraction and as a decimal rounded to 4 decimal places

Answers

Answer:

4. tan(D)=7/24 ≈ 0.2917

tan(F)=24/7 ≈ 3.4286

6. tan(K)=3/5=0.6000

tan(J)=5/3 ≈ 1.6667

Step-by-step explanation:

The tangent is the side opposite of the angle divided by the side adjacent to the angle.

4. tan(D)=7/24 ≈ 0.2917

EF is opposite to D and has length 7. The adjacent side is the side forming the angle that is not the hypotenuse, so it's DE and the length is 24 units.

Do the same thing for the rest of the angles. (You probably already know that acute angles are smaller than 90 degrees, so you have to find the tangent of 2 angles in each problem.) I just used a calculator to divide, but you could do it by hand, and I'm guessing you know how to round. Hope I could help!

Marcos can seal 5 envelopes every minute. Jerry can seal 7 envelopes every minute. They both seal envelopes for 1 hour nonstop.

How many more envelopes does Jerry seal than Marcos? Show your work.

Answer:

Answers

Answer:

120

Step-by-step explanation:

Since,

Marcos seal 5 envelopes every minutes

Jerry seal 7 envelopes every minutes

Both seal envelopes for 1 hour

Knowing that 1 hour = 60 minutes

Thus,

Marcos = 5 × 60 = 300

Jerry = 7 × 60 = 420

Now subtract

420 - 300 = 120

Hence, Jerry seal 120 more than Marcos.

~Lenvy~

Answer:

120 more envelopes

Step-by-step explanation:

Given the following:

⇒ Marcos can seal 5 envelopes every minute.

⇒ Jerry can seal 7 envelopes every minute.

⇒ They both seal envelopes for 1 hour nonstop.

Question to Answer:

How many more envelopes does Jerry seal more than Marcos?

Solution:

Note that: 1 Hour = 60 Minutes

Thus, we can multiply envelopes by 60 minutes

Marcos → 5 × 60 = 300

Jerry → 7 × 60 = 420

Now we have to subtract to see how many more envelopes does jerry seal more than marcos.

420 - 300 = 120

Base on the result, we can conclude that jerry seal 120 more than marcos.

Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.

Answers

Answer:

Step-by-step explanation:

We use a for Adult and s for Student.

Assuming this, you have to start by writing two equations from the information provided:

900 total tickets were sold

a+s=900 ------(i)

they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50

2820=4a+2.5s ------(ii)

lets solve for a in the first equation:

a=900-s

we can plug this into the second equation and solve for s

2820=4(900-s)+2.5s

2820=3600-4s+2.5s

2820=3600-1.5s

-780=-1.5s

s=520

we can plug this into the first equation and solve for a:

a+520=900

a=380

Total adult ticket sold : 380

Total student ticket sold = 520

Cost of adult tickets = 380 * 4 = $1520

Cost of student tickets = 520 * 2.5 = $1300
