Answer:

shrimp cocktail: 0.00 or 0%

lifesaver: 0.25 or 25%

gum: 0.05 or 5%

chocolates or lifesaver: 0.80 or 80%

Not Cracker: 0.85 or 85%

Any treat: 1.00 or 100%

Step-by-step explanation:

First Add all of them together

22+10+6+2=40

now divide

22/40 0.55

10/40=0.25

6/40=0.15

2/40=0.05

add/subtract

0.25+0.55=80%

1-0.15=0.85

Answer:

[tex]20\ lawns = \$240[/tex]

[tex]9 \ lawns = \$108[/tex]

See Attachment for Graph

Step-by-step explanation:

Given

[tex]1\ lawn = \$12[/tex]

Solving (a): Number of lawns in $240

[tex]1\ lawn = \$12[/tex]

Multiply both sides by 20

[tex]20 * 1\ lawn = \$12 * 20[/tex]

[tex]20\ lawns = \$240[/tex]

Solving (b): Cost of mowing 9 lawns

[tex]1\ lawn = \$12[/tex]

Multiply both sides by 9

[tex]9 * 1\ lawn = \$12 * 9[/tex]

[tex]9 \ lawns = \$108[/tex]

To create a graph, we need to generate a formula;

If

[tex]1\ lawn = \$12[/tex]

[tex]2\ lawn = \$24[/tex]

[tex]3\ lawns = \$36[/tex]

[tex]x\ lawns = \$12x[/tex]

So:

The graph formula is

[tex]y = 12x[/tex]

Answer:

b is the correct answer

Option B situations do the quantities combine to make 0.

Arithmetic operations are a set of four basic operations to be performed to add, subtract, multiply or divide two or more quantities. These are also known as mathematical operations.

Addition

The addition is a basic mathematical skill of finding or calculating the total of two or more numbers, or we can say in simple words adding things together. It is denoted by the symbol ‘+’.

Subtraction

The subtraction arithmetic operation shows the difference between two numbers. It is denoted by the symbol ‘-‘. Subtraction is mostly used to find out what is left when things are taken away.

Multiplication

The repeated addition is known as multiplication. It is represented by the symbol ‘×’. Multiplication as an arithmetic operation helps us to find out the total when a number is repeating itself a number of times.

Division

The division is an act of dividing something into equal parts or groups. It is one of the four basic arithmetic operations which gives a fair result of equal sharing.

Option A :

Given

A bird flies 25 feet up in the air. It then flies 25 feet across to its

nest.

So, total distance flown by bird = 25 + 25 = 50 feet

Which do not combine to 0.

Option C :

A player in a game earns 4 points for getting an answer right. She

then earns 4 points for making it around the board.

Hence, total points earned = 4 + 4 = 8

Which do not combine to 0.

Option D :

A car is filled with 10 gallons of gas, Half of the 10 gallons are

then used on a day's drive.​

= 10 - [tex]\frac{1}{2}[/tex] × 10

= 10 - 5

= 5

Which do not combine to 0.

Option B :

Veronica receives $21 for babysitting. She then spends $21 on a

new shirt.

So net amount left with Veronica = 21 - 21 = 0

Hence, it combines to zero.

Answer:

  B, D

Step-by-step explanation:

1. The shaded area is below the solid line at y=1, so the solution set is partially determined by the inequality ...

  y ≤ 1 . . . . . . values of y in the solution set are less than or equal to 1

The shaded area is below the line y=x, so is partially determined by ...

  y -x < 0

These inequalities match the second choice.

__

2. The solid boundary line has a slope, rise/run, of 1/3. The shaded area is below it. So the applicable inequality is ...

  y ≤ 1/3x +6 . . . . . . matches the fourth choice

Answer:

7,260 ways

Step-by-step explanation:

Here, we are told that the president must be a senior and the secretary must be a freshman.

Now for the post of President, we have 15 choices to pick from

For the post of secretary, we have 11 choices to pick from

Now the last position, the vice president

Firstly , we have 14 seniors( 1 already president), 10 freshmen(1 already secretary) , 6 sophomores and 13 juniors

So the total number of choices will be;

14 + 10 + 7 + 13 = 44

So the number of ways will be;

44 * 15 * 11 = 7,260 ways

XY: 15.23

Step-by-step explanation:

Smartness

The distance between the endpoints of line segment XY will be 15.2 units.

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x - h)² + (y - k)²

The endpoints of line segment XY are given below.

X(-9, 2) and Y(5, -4)

The distance between the endpoints of line segment XY will be given as,

D² = (x - h)² + (y - k)²

D² = (5 + 9)² + (-4 - 2)²

D² = (14)² + (-6)²

D² = 196 + 36

D² = 232

D = √232

D = 15.2 units

The distance between the endpoints of line section XY will be 15.2 units.

Answer:

see below

Step-by-step explanation:

given;

Planet Earth has an approximate diameter of 1.2742 x 10¹⁰ millimeters.

The sun has a diameter of 1.391 x 10⁶ kilometers.

find:

Part I:

Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Earth's diameters?

Part II:

Approximate how many times greater the sun's diameter is than planet Earth's.

-------------------------------------------------------------------------------------------------------

part I:

the best measurement to represent the lengths of the sun and Earth's diameters is kilometers.

= planet dia. = 1.2742 x 10¹⁰ mm x            1 km            =  12,742 km  

                                                          1,000,000 mm

= sun dia. = 1.391 x 10⁶ km = 1,391 x 10³ km = 1,391,000 km

part II:

the approximate scale dia ratio of earth to sun is = sun dia. over earth's dia.

=  1,391,000 km

    12,742 km

= 109.17 times

therefore,

109.17 times greater the sun's diameter is than planet Earth's.

Answer:

The answer would be 54 because you would follow the order of PEMDAS

you would do parentheses first which is 8-2 which is 6 then multiplication

so 6x4 = 24 then addition which is 32+24 which equals 56, then you would do 56-6/3 which would equal 54

Answer:

Step-by-step explanation:

This problem is focused on percentages.

Now given that 49% of a number is  1,920,718

we can say let the number be x

so 49% of x=  1,920,718

now expressing this problem mathematically we have

(49/100)*x=  1,920,718

0.49x= 1,920,718

divide both sides by 0.49 we have

x=  1,920,718/0.49

x= 3919832.65306

Therefore the total that were granted degree that year was 3919832.65306

[tex]n = 126[/tex]

Step-by-step explanation:

First let's model this into an equation.

Twice a number is [tex]2n[/tex], and that divided by 6 is [tex]\frac{2n}{6}[/tex]. That's equal to 42, so we have [tex]\frac{2n}{6} = 42[/tex].

Now we can simplify this equation by isolating n on one side of the equation.

Multiply both sides by 6:

[tex]\frac{2n}{6} \cdot 6 = 42\cdot 6\\\\2n = 252[/tex]

Divide both sides by 2:

[tex]2n \div 2 = 252\div 2\\\\n = 126[/tex]
