Step-by-step explanation:

since its asking about pineapple and peaches all you have to do is add pineapple and peaches which will give you 36 and since I added all of the numbers together it will give you 36/47

after that you have to put 36/47 in a decimal

36/47 will give you a decimal of .765957 then you got to multiple that by 100 which will give you 76. many numbers all u got to  do is round that up to 77 and that's how u get ur answer

The true statements are:

The square roots of numbers less than 1 are less than 1.

The square roots of numbers greater than 1 are greater than 1.

The square root is defined as a factor of a number when multiplied by itself, gives the original number.

The given numbers are 0.6 and 1.6. The square roots of given numbers are:

[tex]\sqrt{0.6} = 0.7745[/tex]

[tex]\sqrt{1.6} = 1.2649[/tex]

The first given number 0.6 is less than 1 and its square root is also less than 1. The second given number 1.6 is greater than 1 and its square root is also greater than 1.

Hence we can conclude that the square roots of numbers less than 1 are less than 1 and the square roots of numbers greater than 1 are greater than 1.

Answer:

-24

Step-by-step explanation:

Exponents go first. 4^2=16. 2^3=8. Next multiplication. 5*8=40. Now subtraction. 16-40=-24

Chickens have 2 legs and cows have 4 legs.

Let x = # of chickens and let y = # of cows.

2x + 4y = 118

x + y = 50

x= 50 - y

2(50 - y) + 4y =118

100 - 2y + 4y = 118

2y = 18

y = 9

x = 41

The simplified expression is: 2(2y^3-25y-10)/y

Step-by-step explanation:

Answer:

y2-y

Simplify ———————

y2 - 25

2.1 Pull out like factors :

y2 - y = y • (y - 1)

2.2 Factoring: y2 - 25

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Check : 25 is the square of 5

Check : y2 is the square of y1

Factorization is : (y + 5) • (y - 5)

Final result

4y

Answer:

Cup 1 acts as a control group.

Step-by-step explanation:

Control group: The group used in the experiment by the researchers in which no change in the variable is done. It is then set as a benchmark for the groups which are being tested.

We are given 4 groups which are being experimented for the flotation of an egg in water.

Since in Cup 1, there is no addition of salt

So, there is no change in the variables.

So, by definition of control group .

So, cup 1 acts as a control group since there is no change in the variable .

Hence, the correct answer is Option 1.

Cup 1 acts as a control group.

Step-by-step explanation:

Answer:

Step-by-step explanation:

t + u = 11 ----------- (1 )

10t + u = 10u + t - 9

10t + u - 10u - t = -9

10t - t + u - 10u = - 9

Combine like terms

9t - 9u = -9

Divide the entire equation by 9

[tex]\dfrac{9}{9}t-\dfrac{9}{9}u=\dfrac{-9}{9}[/tex]

t - u = -1  --------------(2)

Add equation (1) & (2) and so, u will be eliminated and we can find the value of t

(1)       t + u = 11

(2)      t  - u = -1

         2t     = 10

               t = 10/2

t = 5

Plugin t = 5 in equation (1)

5 + u = 11

    u = 11 - 5

u = 6

The original number is 56

The expression representing the amount of money that was raised for each member of the club is [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, [tex]a \div b = a[/tex] divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since [tex]a = a \times 1[/tex] so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )

Profit earned is the extra money which we make after deducing the cost price of the process we're doing.

So, we get:

Profit earned = Total amount earned - Amount spent initially for preparation to earn

P = Selling price (S.P.) = Cost price (C.P.)

For the given case, we're given that:

The money raised = Amount made by selling popcorn - amount costed to the club for getting popcorn

Money raised = $627.50 - $95.0

If it is given that: m = number of members in the considered club, then:

Money each member of the considered club will get = Money raised divided in equal m parts = [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

(we don't write symbols like of currency generally, and understand it from context.)

Thus, the expression representing the amount of money that was raised for each member of the club is [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

Answer:

the slope is 0.

Explanation:

[tex]\hookrightarrow \sf \frac{2}{3} - 4y = 8[/tex]

[tex]\hookrightarrow \sf - 4y = 8- \frac{2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{24}{3} - \frac{2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{24-2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{22}{3}[/tex]

[tex]\hookrightarrow \sf y = \frac{22}{-12}[/tex]

[tex]\hookrightarrow \sf y = -\frac{11}{6}[/tex]

[tex]\hookrightarrow \sf y = -1\frac{5}{6}[/tex]

comparing with the formula: y =  mx + b

                               where m is slope and b is y-intercept.

we found that there is no x. so the value of slope will be 0x. slope = 0
