one number is three more than twice a second number. If the sum of the two numbers is 33, what is the product of the two numbers?

Answer:

2 50ml bottles

Step-by-step explanation:

Reading through the question, we have:

For 80mL

[tex]C_1 = \pounds 55[/tex]

For 2 50mL bottles.

The cost is calculated by the original cost + half the original cost.

i.e.

[tex]C_2 = \pounds 45 + \frac{1}{2} * \pounds 45[/tex]

[tex]C_2 = \pounds 45 + \pounds 22.5[/tex]

[tex]C_2 = \pounds 67.5[/tex]

Next, is to calculate the unit price of each.

For 80mL

[tex]C_1 = \pounds 55[/tex]

[tex]Unit\ price = 55/80[/tex]

[tex]Unit\ price = 0.6875[/tex]

For 2 50mL bottles.

[tex]C_2 = \pounds 67.5[/tex]

[tex]Unit\ price - 67.5/(2 * 50)[/tex]

[tex]Unit\ price = 67.5/100[/tex]

[tex]Unit\ price = 0.675[/tex]

By comparison, the 2 50mL is the best buy because it has smaller unit price

Answer:

9:3

Step-by-step explanation:

Please find attached the information required to answer this question

From the upper right corner, there are 8 people who do not like reading.

On the lower right corner of the table, there is 1 one person who does not like reading and playing video games

On the lower left corner, there are two people who do not like playing video games.

The total number of people who do not like reading = 8 + 1 = 9

The total number of people who do not like playing video games = 2 + 1 = 3

= 9 : 3

Answer:

Step-by-step explanation:

1) 5/12

To make the denominator to 36, 12 should be multiplied by 3. As we are multiplying the denominator by 3, numerator also should multiplied by 3

[tex]\frac{5}{12}=\frac{5*3}{12*3}=\frac{15}{36}[/tex]

2) 1/6

[tex]\frac{1}{6}=\frac{1*6}{6*6}=\frac{6}{36}\\[/tex]

3) 7/9

[tex]\frac{7}{9}=\frac{7*4}{9*4}=\frac{28}{36}[/tex]

Answer:

x = 180

∠DBC = 23

∠ABC = 157

Step-by-step explanation:

A straight line is always 180 degrees

A to D line = 180

6x + 19 + x = 180

7x + 19 = 180

      -19     -19

7x = 161

/ 7     / 7

161 /7 = 23

x = 23

Then plug it in

6x + 19

6 ( 23 ) + 19 = 157

x

x = 23

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

1)

mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65

Given that the confidence level (c) = 90% = 0.9

α = 1 - c = 0.1

α/2 = 0.05

The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65

The margin of error (E) is given as:

[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.65*\frac{2.3}{\sqrt{65} } =0.47[/tex]

The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)

2)

mean (μ) = 23, SD(σ) = 12, sample size (n) = 45

Given that the confidence level (c) = 88% = 0.88

α = 1 - c = 0.12

α/2 = 0.06

The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56

The margin of error (E) is given as:

[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.56*\frac{12}{\sqrt{45} } =2.8[/tex]

The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)

Answer:

1046.86344 or 1046.86

Step-by-step explanation:

volume of a sphere is (4/3) · π · r^3, so you can plug in the values and get--

(4/3)*3.14*6.3^3 which gives you 1046.86344

Answer:

1046.86 cubic inches of air

Step-by-step explanation:

Hello There!

Essentially what this question is asking for is the volume of a sphere

To put it in a more understandable way,  A ball usually has a spherical shape and if the inside space (volume) is filled up then how much cubic inches of air will the ball require to fill it up given that the radius of the ball inflated is 6.3 inches

The formula for volume of a sphere is

[tex]V=\frac{4}{3} \pi r^3[/tex]

where r = radius

we are given the radius so all we have to do is plug in the value into the formula so

[tex]V=\frac{4}{3} \pi 6.3^3\\6.3^3=250.47\\\\250.47*\frac{4}{3} =333.396\\\\333.396*3.14=1046.86344\\V=1046.86344[/tex]

our final step is to round to there nearest hundredth

so we can conclude that 1046.86 cubic inches of air will occupy the inflated balloon

Answer:

in triangle PQR

relationship between base and perpendicular is given by tan angle

tan 62=p/b

tan62=x/8.6

x=tan62×8.6=16.17ft

the length of QR to the nearest tenth of a foot is 16ft.

Step-by-step explanation: you need to isolate x so you would divide both sides of the equation of with six which leaves you with x= 4

Answer:

The first step is to divide each side by 6.

Step-by-step explanation:

To get the answer you need to get the x alone which is why you need to divide each side by 6.

Answer:

All the Years since First Grade

No, you would not include Preschool

Step-by-step explanation:

Technically, for this question, you would put the number of years since you began learning basic math. For the vast majority of children, they begin learning Basic Math such as adding and subtracting whole numbers in First Grade. Therefore, you would include all of the years since First Grade. Preschool usually teaches children about numbers and how to count, as well as develop their social skills. Preschool does not teach basic math because the children are just learning about numbers.

Answer:

16^2 = 8^2 + x^2

x^2 = 16^2  -8^2

x^2 = 256 -64

x^2 = 192

x = sq root (192) =  13.8564064606

Complete Question:

Complete each equation, so the statement about its solution is true.

No solutions:

6-3+4x+1= __x + __

One solution:

6-3+4x+1= __x + __

Infinitely many solutions:

6-3+4x+1 = __x + __

Answer:

[tex]4 + 4x = 4x + 3[/tex] --- No solution

[tex]4 + 4x = 3x + 2[/tex] --- One solution

[tex]4 + 4x = 4 + 4x[/tex] --- Infinitely Many solution

Step-by-step explanation:

Solving (a): No solutions

6-3+4x+1= __x + __

Collect like terms

6-3+1+4x= __x + __

4+4x= __x + __

To get no solution, the coefficient of x on both sides must be the same. However, the constant must be different.

So, we can equate the expression to:

[tex]4 + 4x = 4x + 3[/tex]

Solving (b): One solution

6-3+4x+1= __x + __

This gives (same as (a))

4+4x= __x + __

To get one solution, the coefficient of x on both sides must be different. The constant can have any value.

So, we can equate the expression to:

[tex]4 + 4x = 3x + 2[/tex]

Solving (c): Infinitely many solutions

6-3+4x+1= __x + __

This gives (same as (a))

4+4x= __x + __

To get infinitely many solutions, both sides of the equation must be equal.

So:

[tex]4 + 4x = 4 + 4x[/tex]
