Daniel works in a market

He has large bags of potatoes that weighs 26 1/4

Daniel is going to sell them in smaller bags 9/4 pounds each

Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows

= 26 1/4 ÷ 9/4

= 105/4 ÷ 9/4

= 105/4 × 4/9

= 105/9

= 11 6/9

Point C

Hope This helps!! : }

The point D represents the product of the three integers.

Number line is defined as the straight line drawn horizontally where the integers are placed at an equally spaced way.

Integers includes natural numbers, 0 and negative of the natural numbers.

Given is the three numbers 5, -2 and -1.

We have to find the product of these three numbers.

When multiplying integers, negative multiplied to negative and positive multiplied to positive gives positive. If one of the number is negative and other is positive, then the result is negative.

(5) (-2) (-1) = (5 × -2) (-1)

                = (-10) (-1)

                = 10

Hence the product of the three integers 5, -2 and -1 is 10 which is marked as point D on the number line.

Step-by-step explanation:

just plugged in 4 for x

y=1.5(4)+3

hope this helps and is right haha <3

Given:

The statement is

[tex]f(3)=75[/tex]

To find:

The interpretation for the given statement.

Solution:

We know that,

[tex]f(x)=y[/tex]        ...(i)

Here, x is the input value and y is the output value.

We have,

[tex]f(3)=75[/tex]       ...(ii)

On comparing (i) and (ii), we get

[tex]x=3,y=75[/tex]

It means, the output value of the function f(x) is 75 at x=3.

Answer:

r = 2.04%

Step-by-step explanation:

r = n{(A/P)^1/nt - 1}

Where,

r = interest rate = ?

n = number of periods = 12

A = future value = $22,960

P = present value = $20,960

t = time = 4 years

r = n{(A/P)^1/nt - 1}

r = 12{(22,960/20,987)^1/12*4 - 1}

= 12{(1.09)^1/48 - 1}

= 12{(1.09)^0.02 - 1}

= 12 (1.0017 - 1)

= 12(0.0017)

= 0.0204

r = 0.0204 × 100

= 2.04%

r = 2.04%

Answer:

x=20/3 y=17/3

Step-by-step explanation:

1. x-y=1

2. 2x+y=19

The first equation can be rewritten as 2x-2y=2

We can then subtract the second equation from this:

2x-2y=2

2x+y=19

-3y=-17

y=17/3

Plug this into to solve for x:

x-17/3=1

x=17/3+1

x=20/3

Answer:

if -5n+7<57, then n>-10.

if 6n+2<8, then n<1.

Step-by-step explanation:

-5n+7<57

1. subtract 7 from both sides:

-5n+7 -7< 57 -7

-5n<50

2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):

-5n ÷-5<50 ÷-5

n>-10

6n+2<8

1. subtract 2 from both sides:

6n+2 -2<8 -2

6n<6

2. divide both sides by 6:

6n ÷6<6 ÷6

n<1

Answer:

The slope, -3

The y-intercept, -2

The equation (0 -(-2) ) / (1 - (-5))

Step-by-step explanation:

Note: It the given equation the coefficient of [tex]x^2[/tex] must be -16 instead of 16.

Given:

Consider the height  of the water balloon over  time can be modeled by the  function

[tex]y=-16x^2+160x+50[/tex]

To find:

The maximum height of the water balloon  after it was thrown.

Solution:

We have,

[tex]y=-16x^2+160x+50[/tex]

Here, leading coefficient is negative. So, it is a downward parabola and vertex of a downward parabola, is the point of maxima.

If a parabola is [tex]f(x)=ax^2+bx+c[/tex], then

[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]

Here, [tex]a=-16,b=160,c=50[/tex]. So,

[tex]-\dfrac{b}{2a}=-\dfrac{160}{2(-16)}[/tex]

[tex]-\dfrac{b}{2a}=-\dfrac{160}{-32}[/tex]

[tex]-\dfrac{b}{2a}=5[/tex]

Now, put x=5 in the given equation.

[tex]y=-16(5)^2+160(5)+50[/tex]

[tex]y=-16(25)+800+50[/tex]

[tex]y=-400+850[/tex]

[tex]y=450[/tex]

The vertex of the given parabolic equation is (5,450).

Therefore, the maximum height of the balloon is 450 units after 5 units of time.

Answer:

D; A⊂U is true and A'={9, 10, 12, 14}

Step-by-step explanation:

A={11,13}

Because those numbers are included in the statement U={9,10,11,12,13,14}, we can say that it's true that A belongs to U.

A' is the numbers of U not including A. So, it would just be U without the 11 and 13, or {9,10,11,12}

Answer:

Approximately 58.4%

Step-by-step explanation:

The probability that they are different is the opposite of the probability that they are the same.

The probability that they are the same is:

P(plain, plain) = (12/20) (11/19) = 132 / 380

P(chocolate, chocolate) = (5/20) (4/19) = 20 / 380

P(currant, currant) = (3/20) (2/19) = 6 / 380

P(same) = 132/380 + 20/380 + 6/380

P(same) = 158/380

P(same) = 79/190

Therefore, the probability that they are different is:

P(different) = 1 − 79/

[tex]\frac{111}{190}[/tex]  is the  probability that the two biscuits were of not the same type.

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

According to question, Carolyn has 20 biscuits in a tin.

She has 12 plain biscuits, 5 chocolate biscuits and 3 ginger biscuits

Carolyn takes at random two biscuits from the tin.

We have to find out  the probability that the two biscuits were of  not the same type.

             P(plain biscuit, plain biscuit)  [tex]=(\frac{12}{20} )(\frac{11}{19} )=\frac{132}{380}[/tex]

P(chocolate biscuit, chocolate biscuit)[tex]=(\frac{5}{20})(\frac{4}{19} )=\frac{20}{380}[/tex]

          P(ginger biscuit, ginger biscuit)[tex]=(\frac{3}{20}) (\frac{2}{19})=\frac{6}{380}[/tex]

Probability of same type of biscuits

[tex]=\frac{132}{380} +\frac{20}{380}+\frac{6}{380}[/tex]

[tex]=\frac{79}{190}[/tex]

The probability that the two biscuits were not of the same type.

[tex]=1-\frac{79}{190}[/tex]

[tex]=\frac{111}{190}[/tex]

Hence, we can conclude that [tex]\frac{111}{190}[/tex]  is the  probability that the two biscuits were not of the same type.

The coldest temperature at Antarctica is -89.6 degrees celsius

Step-by-step explanation:

Here, we are interested in calculating the coldest temperature in Antarctica.

In the question, we are simply told that the coldest Antarctica temperature was 40.6 colder than the average winter temperature at the south pole.

The average winter temperature at south pole = -49 degree celsius

The coldest temperature is thus -49-40.6 = -89.6 degrees celsius

Step 1: Simplify both sides of the equation.

−5(x+1)+3x−3=−14

(−5)(x)+(−5)(1)+3x+−3=−14(Distribute)

−5x+−5+3x+−3=−14

(−5x+3x)+(−5+−3)=−14(Combine Like Terms)

−2x+−8=−14

−2x−8=−14

-5(x + 1) + 3x - 3 = -14

Distribute within parenthesis

-5x -5 + 3x - 3 = -14

Combine like terms

-2x - 8 = -14

Add 8 to both sides

-2x = -6

Divide -2 by both sides

x = 3
