Answer:

Since 15 is greater than 8, the correct expression will be:

15 > 8

Since 4 is less than 134, the correct expression will be:

4 < 134

Since 3 is less than 5, the correct expression will be:

3 < 5

Since 351 is greater than 215, the correct expression will be:

351 > 215

Step-by-step explanation:

The greater a decimal is, the closer it is to one whole. The smaller a decimal is the farther it is from one whole. The first thing you need to look at is the digit number in each decimal. These each have two digits in them, so you can compare them right away

Answer:

1) irrational

2) is A.

Step-by-step explanation:

you're welcome

The required solution is as follows,
(1) the given number is an irrational number. Option D is correct.
(2)  π is an irrational number. Option D is correct.

Rational numbers are numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.

Here,
(1)

Given number,
0.101001000100001…
Since the given number has repeating decimals so, it is an irrational number.

(2)
π
Since π also an irrational number, because it value, is nonterminating and repeating.

Thus, the required solution is as follows,
(1) the given number is an irrational number. Option D is correct.
(2)  π is an irrational number. Option D is correct.

If I'm not mistaken that would be A.

Step-by-step explanation:

I haven't done this since 6th and 7th grade and I'm in 8th. I think you're supposed to multiply the base 4 times by 6 giving you 72 then multiply it by 5.1 and divide it by 2 that would give you that answer.

Answer:

divide three from both sides to get x > 4

Answer:

No

Step-by-step explanation:

You only need to flip your sign when dividing by a negative. 3x > 12 = x > 12/3 = x > 4. If the equation were -3x > 12, then it would be x < 4.

Answer:

185 units.

Step-by-step explanation:

So first, I subtracted: 250 - 120 = 130

I divided 130 by 2. I got 65.

I subtracted 65 from 250 and I got 185.

Proof it is correct:

185 - 120 = 65

AND

250 - 185 = 65

1) True (Intersection is (2, 140)

2) False

3) Not sure, but I'm leaning towards F

4) True

Image 2: -4

Step-by-step explanation:

y = 50x + 40

y = 60x + 20

y = 50(6) + 40 = 340

y = 60(6) + 20 = 380

140 = 50x + 40

50x = 100

x = 2

140 = 60x + 20

60x = 120

x = 2

The answer is below

Step-by-step explanation:

a) The number of pupils who scored more than 7 in a test = pupils who shored  8 + pupils who shored 9 + pupils who shored 10

The number of pupils who scored more than 7 in a test = 7 + 3 + 1 = 11 pupils

b) Total number of pupils = pupils who shored  0 + pupils who shored 1 + pupils who shored 2 + . . . + pupils who shored 9 + pupils who shored 10

Total number of pupils = 0 + 1 + 4 + 0 + 0 + 8 + 0 + 2 + 7 + 3 + 1 = 26 pupils

c) It is assumed that nobody scored either 0 or 3 or 4 or 6. Also the highest mark was assumed to be 10

Answer:

A

Step-by-step explanation:

Hello there

The coefficient correlation is set on a scale of 1 to -1

1 having the strongest correlation, 5 having an ok correlation and 0 having no correlation

.193 is closest to 0 so the correlation is very weak

Remember if the coefficient correlation is positive the it will have a positive correlation and if its negative then it will have a negative correlation

So we can conclude that the answer is A

Answer:

[tex]y = \frac{-3}{4}[/tex]

Step-by-step explanation:

[tex]\frac{y}{2} + \frac{1}{4} = \frac{y}{6}[/tex]

Lets take all the variable terms in L.H.S & all the constant terms in R.H.S.

(While taking a term from one side to another side , it's sign changes )

⇒ [tex]\frac{y}{2} - \frac{y}{6} = -\frac{1}{4}[/tex]

Now in L.H.S. , lets solve the fractions and reduce its numerator and denominator .

⇒  [tex]\frac{3y - y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{2y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{y}{3} = -\frac{1}{4}[/tex]

Lets multiplying 3 on both the sides .

⇒  [tex]\frac{y}{3} \times 3 = -\frac{1}{4} \times 3[/tex]

⇒  [tex]y = \frac{-3}{4}[/tex]

Answer: $5

Step-by-step explanation:

Let the small candy be represented by x.

The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x

The large candy was $5 more than the medium candy. This will be: = 2x + 5

Since Jason spent a total of $30 on

candy, the cost of the small candy will be:

x + 2x + 2x + 5 = 30

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25/5

x= 5

The small candy cost $5
