Answer:

She needs to get 8 bags of spoon and 1 bag of fork

Step-by-step explanation:

Here in this question, we want to know the least number of spoons and the least number of bags to be bought so that there are same number of each.

Basically, to calculate this, we need the lowest common multiple of 16 and 2. The lowest common multiple of both is 16 (2 is a factor of 16)

So the lowest number of each she can buy to have the same number of pieces is 16.

Kindly recall that spoons come in bags of 2. So to achieve the 16, she needs 8 bags.

Since fork comes in bag of 16, to achieve 16, she only need a single bag of fork.

Answer:

1x+46 is the answer

Step-by-step explanation:

=4(-8x + 5) – (-33x – 26)

opening brackets to simplify

=-32x+20+33x+26

=-32x+33x+20+26

=1x+46 is the answer

hope it will help :)

Answer:

x+46

Step-by-step explanation:

4(-8x + 5) – (-33x – 26) ​

The first step is to distribute and simplify.

4 distributed to -8x will be -32x, and same thing goes with 5, which is 20.

-

The first part of the equation is -32x+20

Now, this is where it gets confusing.

If there is a sign before a pair of parentheses, you always put 1. In this case, it's -1 distributed to -33x and -26.

So, the second part of the expression will be +33x+26

The whole expression is

-32x + 20 + 33x + 26

add like terms, -32x+33x= x.

20+26=46.

The answer is x+46.

Step-by-step explanation:

Answer:

y = 4

Step-by-step explanation:

Given that y varies jointly with x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = 16 when x = 4 and z = [tex]\frac{1}{2}[/tex] , that is

16 = k × 4 × [tex]\frac{1}{2}[/tex] = 2k ( divide both sides by 2 )

8 = k

y = 8xz ← equation of variation

When x = 2 and z = [tex]\frac{1}{4}[/tex] , then

y = 8 × 2 × [tex]\frac{1}{4}[/tex] = 16 × [tex]\frac{1}{4}[/tex] = 4

Step-by-step explanation:

[tex] = \frac{20}{5} . {2}^{ - 3} [/tex]

[tex] = 4. \frac{1}{ {2}^{3} } [/tex]

[tex] = \frac{4}{2 \times 2 \times 2} [/tex]

[tex] = \frac{4}{8} [/tex]

[tex] = \frac{1}{2} [/tex]

Answer:

  -13

Step-by-step explanation:

As per the order of operations, you do the parentheses first. g(5) is inside the parentheses of f(g(5)).

  g(5) = -3(5) +5 = -10

Then ...

  f(g(5)) = f(-10) = 2(-10) +7

  f(g(5)) = -13

Answer:

Step-by-step explanation:

[tex]7+4y=39\\\\\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}\\7+4y-7=39-7\\\\\mathrm{Simplify}\\4y=32\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\frac{4y}{4}=\frac{32}{4}\\\\Simplify\\y =8[/tex]

Answer:

y = 8

Step-by-step explanation:

7 + 4y = 39

Rearrange:

4y + 7 = 39

Subtract 7 from both sides:

4y + 7 = 39

     - 7     -7

4y = 32

Divide both sides by 4:

4/4 = y

32/4 = 8

y = 8

Answer:

1/2 of the dots

Step-by-step explanation:

The number of dots in a 5 by 8 array is 5*8 = 40 dots

The number of dots in the t is 20

faction = part/ whole

20/40 = 1/2

its  1/2

8x5=40

40/20=1/2

The situation that is an example of an observational study is " Having customers fill out a questionnaire about their favourite brand of toothpaste".

When researchers monitor the effect of a risk factor, diagnostic test, therapy, or other intervention without attempting to influence who is or is not exposed to it in observational studies.

For example: Consider someone standing on a popular street in a New York neighbourhood asking passers-by how many dogs they have, then analyzing the data to see if more pet food businesses are needed in the area.

As we know that in an observational study, the sample whose test/survey is been taken is completely random.

Therefore, the situation that is an example of an observational study is " Having customers fill out a questionnaire about their favourite brand of toothpaste".

Step-by-step explanation: Collecting the blood pressure readings of a group of elderlyindividuals in a small town

Answer:

[tex]Rate = \$0.23[/tex]   and    [tex]Rate = \$0.094[/tex]

Step-by-step explanation:

Given

Sew-on logos

Cost = $2.30

Units = 10

Stick-on logos

Cost = $9.40

Units = 100

Required

Divide cost by units, in both cases

When we divide cost by units, it gives the unit rate.

i.e.

[tex]Rate = \frac{Cost}{Units}[/tex]

FOR SEW-ON LOGOS

Substitute $2.30 for Cost and 10 for Units

[tex]Rate = \frac{\$2.30}{10}[/tex]

[tex]Rate = \$0.23[/tex]

FOR STICK-ON LOGOS

Substitute $9.40 for Cost and 100 for Units

[tex]Rate = \frac{\$9.40}{100}[/tex]

[tex]Rate = \$0.094[/tex]

Hence, the solution is

[tex]Rate = \$0.23[/tex]   and    [tex]Rate = \$0.094[/tex]

Answer:

£7448

Step-by-step explanation:

Simple interest (I) is calculated as

I = [tex]\frac{PRT}{100}[/tex]

P is principle ( amount invested), R is rate of interest and T is time in years.

Here P = £5600, R = 11 and T = 3 , thus

I = [tex]\frac{5600(11)3)}{100}[/tex] = £1648

Value after 3 years = £5600 + £1848 = £7448

Step-by-step explanation:

start from f(g(x))

f(g(x))= 3(g(x)) -2

f(g(x))= 6x -2

h(f(g(x)))=(f(g(x)))² -5(f(g(x)))

h(f(g(x)))=(6x-2)² -5(6x-2)

h(f(g(x)))=36x²-24x+4-(30x-10)

h(f(g(x)))=36x²-24x+4-30x+10

h(f(g(x)))=36x²-54x+14

Answer:150

Step-by-step explanation:

600/4=150  (150)3=450  450+150=600

Answer: 150 dollars

Step-by-step explanation: Because the dryer is equal to washer divided by 3 you can substitute Washer/3 in the equation

W+ W/3=600

multiply both sides by 3

3W+W=1800

4W=1800

Divide both sides by 4

The answer to W is 450 dollars which you then divide by three to get 150 dollars

Answer:  8

Step-by-step explanation:

EQ1:   a + b + c = 2            -->       b + c = 2 - a

EQ2:  ab + bc + ac = -1     -->        b + c = (-1 - bc)/a

EQ3:  abc = -2                  -->           bc = -2/a

Set EQ1 = EQ2 and substitute bc using EQ3 to solve for "a":

[tex]2-a=\dfrac{-1-bc}{a}\\\\\\\text{Clear the denominator:}\\a(2-a)=-1-bc\\\\\text{Substitute bc:}\\a(2-a)=-1-\dfrac{-2}{a}\\\\\\\text{Clear the denominator:}\\a^2(2-a)=-a+2\\\\\\\text{Simplify and set equal to 0:}\\2a^2-a^3=-a+2\\0=a^3-2a^2-a+2\\\\\text{Factor:}\\0=a^2(a-2)-1(a-2)\\0=(a^2-1)(a-2)\\\\\text{Solve for a:}\\a^2-1=0\qquad a-2=0\\a=\pm1}\qquad \qquad a=2[/tex]

Consider the solution a = 2 and plug it into EQ1 to solve for "b"

b + c = 2 - 2

b + c = 0

b = -c

Plug in a = 2, b = -c, and c = c into a³ + b³ + c³

  2³ + (-c)³ + c³

= 8 - c³ + c³

= 8

Answer:

a = -1 and

b = 10

Step-by-step explanation:

Given:

h(x) = (x – 1)³ + 10

h(x) = (g compose f)(x).

f(x) = x + a and

g(x) = x³ + b

To find:

The values of a and b = ?

Solution:

First of all, let us have a look at the composite functions.

(g compose f)(x) means we replace the value of [tex]x[/tex] with [tex]f(x)[/tex] in the function [tex]g(x)[/tex].

We know that:

[tex]g(x) =x^3+b[/tex] and

[tex]f(x) = x + a[/tex]

Let us find (g compose f)(x) by replacing [tex]x[/tex] with [tex]x+a[/tex]

[tex](g\ compose\ f)(x) = (x+a)^3+b[/tex]

Also, h(x) = (g compose f)(x) = (x – 1)³ + 10

Therefore,

[tex](x - 1)^3 + 10 = (x+a)^3+b[/tex]

Comparing the corresponding elements of the above expressions:

we get a = -1 and

b = 10

Answer:

a: -1

b: 10

Answer:

15500 pounds

Step-by-step explanation:

The weight of one load is 4 tons and the weight of other load is 7500 pounds.

We know that, 1 ton = 2000 pounds

4 tons = 8000 pounds

Total weight = 8000 pounds + 7500 pounds

Total weight = 15500 pounds

So, the total weight of sand is 15500 pounds.
