Final answer:

To solve for the missing fraction in the equation blank + 1/16 = 3/2, convert 3/2 to a fraction with a denominator of 16 to give 24/16. Then, subtract 1/16 from 24/16 to get the missing fraction, which is 23/16.

Explanation:

To find the missing fraction in the equation blank + 1/16 = 3/2, we first need to express 3/2 with the same denominator as 1/16 to facilitate addition. The common denominator for 16 and 2 is 16, so we can rewrite 3/2 as 24/16 (since 3 × 8 = 24 and 2 × 8 = 16). Our equation now is blank + 1/16 = 24/16. To solve for the missing fraction (blank), we subtract 1/16 from 24/16, which gives us 23/16.

Example:

Rewrite 3/2 as 24/16

Subtract 1/16 from 24/16 to find the missing number

The missing fraction is 23/16

This method demonstrates how to find a missing fraction by creating a common denominator and then subtracting to isolate the missing number.

Given:

Ratio of white and blue paint is 2:3

Total quantity of paint is 20 litres

To find:

Quantity of blue paint to be mixed so that the ratio of white paint to blue paint becomes 1:7

Solution:

The ratio 2:3 totals 20 that is [tex]2x+3x=20\rightarrow5x=20\rightarrow x=4[/tex]

So, the quantity of white paint in the mixture is [tex]2\times4=8[/tex] and the quantity of blue paint in the mixture is [tex]3\times4=12[/tex]

Now, to get the final ratio as 1:7, Mary should have [tex]7\times8=56 \text{ litres }[/tex] of blue paint. So, she need to add [tex]56-12=44 \text{ litres}[/tex].

Therefore, Mary has to add 44 litres of blue paint to the mixture to make the ratio as 1:7.

Answer:

34

Step-by-step explanation:

ok so first you need to divide 144 by 12 = 12

then you need to figure if you split that in half it equals 6.

now we know that for every 12 miles you drive, you need 1 gallon of gas

now you need to divide 240 by 6 = 40

so you will need 40 gallons of gas to drive that far

we are not one yet, then you need to take away 6 from 40 witch comes to 34.

so you will need 34 more gallons of gas

Answer:

Eric should order 9 boxes of programs.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Probability of buying a program for the game = 1/2

Number of people at the game = 900

Number of programs per box = 50

2. How many boxes of programs should Eric order?

Let's calculate the answer this way:

Number of programs required for the next football game = Probability of buying a program for the game * Number of people at the game

Replacing with the values given, we have:

Number of programs required for the next football game = 1/2 * 900

Number of programs required for the next football game = 450

Now, we can calculate he number of boxes, this way:

Number of boxes of programs Eric should order = Number of programs required for the next football game /Number of programs per box

Replacing with the values given, we have:

Number of boxes of programs Eric should order = 450/50

Number of boxes of programs Eric should order = 9

Question:

A rectangular prism has a length of 4 1/2 millimeters, a width of 4 1/2 millimeters, and a height of 6 millimeters.

Sally has a storage container for the prism that has a volume of 143 cubic millimeters.

What is the difference between the volume of the prism and the volume of the storage container?

Answer:

The difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter

Solution:

Volume of rectangular prism is given as:

[tex]volume = length \times width \times height[/tex]

From given,

[tex]length = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\width = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\height = 6\ mm[/tex]

Therefore,

[tex]volume = \frac{9}{2} \times \frac{9}{2} \times 6 = 121.5\ mm^3[/tex]

Sally has a storage container for the prism that has a volume of 143 cubic millimeters

What is the difference between the volume of the prism and the volume of the storage container

Difference = 143 - 121.5 = 21.5

Thus difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter

There are 5 ways in which 10 cookies can be sold in singly or in packages of 4 or 6.

Given that,
cookies are sold singly or in packages of 4 or 6. with this packaging, how many ways can you buy exactly 10 cookies is to be determined.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

Ways in which exactly 10 cookies can be sold,
= {10 cookies singly, pack of 4 cookies and 6 cookies singly, pack of 4 and pack of 6, 4 cookies singly and a pack of 6 and 2 pack of 4 and two cookies singly,}
= 5 ways

Thus, there are 5 ways in which 10 cookies can be sold in single or in packages of 4 or 6.

Answer: 24 units.

Step-by-step explanation: Count out how many units long AB is. AB goes from -3 to 3, for a length of 6 units.

Count out how long AC is. AC goes from 4 to -4, for a length of 8 units.

To find BC, use the Pythgorean theorem (a^2+b^2=c^2). 8^2 is 64, and 6^2 is 36. Add 64 and 36 to get 100. Then find the square root of 100, which is 10.

Add all the lengths. 6+8+10=24.

Answer:

12 weeks

Step-by-step explanation:

If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72

In one week → $6

2 weeks → $12

3 weeks → $18

and so on..

[tex]\frac{72}{6} = 12[/tex]

John will need 12 more weeks to save a total of $100.

Answer: The two numbers are 33 and 14

Step-by-step explanation: We shall start by first assigning letters to unknown variables. Therefore let the two numbers be called a and b. The first clue in this question states that the sum of both a and b equals 47. That means we can write the expression;

a + b = 47.

The second clue states that their difference equals 19. This also can be expressed as follows;

a - b = 19

Now we have a pair of simultaneous equations which are

a + b = 47 ———(1)

a - b = 19 ———-(2)

We shall use the substitution method. Therefore from equation (1), make a the subject of the equation.

a = 47 - b

Next we substitute for the value of a in equation (2)

a - b = 19

47 - b - b = 19

47 -2b = 19

By collecting like terms we now have 47 - 19 = 2b

28 = 2b

Divide both sides of the equation by 2

14 = b

We can now substitute for the value of b into equation (1)

a + b = 47

a + 14 = 47

Subtract 14 from both sides of the equation

a = 33.

Therefore the two numbers are 33 and 14.

The two numbers with a sum of 47 and a difference of 19 are 33 and 14. We found this by setting up two equations based on the given information and solving for the two variables.

The sum of two numbers is 47 and the difference is 19. To find these two numbers, we can set up a system of equations and solve them. Let the numbers be x and y.

Adding both equations, we get 2x = 66, hence x = 33.

Substituting x in equation 1, we get 33 + y = 47, hence y = 47 - 33 = 14.

Therefore, the two numbers are 33 and 14.

Answer:

The far of reaching the wall

24  71

=69.70106106ft

Step-by-step explanation:

The wooden beam reaches a height of 6 meters on the wall.

To find the height of the beam on the wall, we can use trigonometry.

The given angle is 71 degrees and the length of the beam is 6 meters.

We can use the sine function to find the height. The formula is: height = length * sin(angle).

height = 6 * sin(71)

Using a calculator, we find that the height is approximately 5.753 meters.

Rounding to the nearest meter, the beam reaches a height of 6 meters on the wall.

Step-by-step explanation:

We are given the function:

We have to find the range of the given function.

Range of function

Range of basic sine function is

[tex]-1\leq \sin(x) \leq 1[/tex]

Multiplying the range by -5

[tex]5\geq -5\sin(x) \geq -5[/tex]

Thus, the range of given function is

Answer:

g = 5

Step-by-step explanation:

8 g + 10 = 35 + 3 g

in order to get the value of g, firt of all rearrange the expression or in ither words collect the like terms.

8 g + 10 = 35 + 3 g

8g + 10 - 3g = 35

NOTE; when you are moving a number with positive sign across the equal to = sign the positive changes to negative and same thing applies to the negative sign it changes to positive sign.

we have;

8g -3g = 35 - 10

5g = 25

divide both sides by 5

5g/5 = 25/5

Second, lets find how many miles the cyclist can ride per hour.
