Answer:

13- 25 fish

14- 9 miles

15- 7.825 ft3

16- 11.3 feet

Step-by-step explanation:

13-

        14 x 2 = 28 fish

        He dropped three things so:

        28 - 3 = 25 fish

14-

         7 days x 3weeks = 21 days

         3laps x 21 days = 63 laps

         63 laps x 1/7 mile = 9 miles

15-

         all his savings: 2.6 + 7.34 + 5.71 = 15,65 ft3    

         melted snow = 15.65 / 2 = 7.825 ft3

16-

         3.5 - 1.8 = 1.7 feet

         1.7 + 9.6 = 11.3 feet

Answer:

Step-by-step explanation:

# 13.

I assume there will be no bonus, because penguin dropped some things.

14 × 2 - 3 × 1 = 25 fish

# 14.

3 laps, [tex]\frac{1}{7}[/tex] mile, 7 days, 3 weeks

3 × [tex]\frac{1}{7}[/tex] × 7 × 3 = 9 miles

# 15.

[tex]\frac{2.6+7.34+5.71}{2}[/tex] = 7.825 ft³

# 16.

[tex]3\frac{1}{2}[/tex] = 3.5

+ 3.5 - 1.8 + 9.6 = (3.5 + 9.6) - 1.8 = 11.3 ft.

what was the answer I’m on the same one

Answer:

1/2 or 50% probability

Step-by-step explanation:

There are just two players, player A and player B. Since it is between this two players, for player A to score first we would have:

AB where player A is the first player to score, we wouldn't have BA since player would not be the first here

Probability = number of favorable outcomes/total number of outcomes

Therefore probability of A being the first player = number of A/total number of players

=1/2 = 0.50

There is therefore a 50% chance of A being the first player

Answer:

x=3

y=4

Step-by-step explanation:

I'm using 3x+y=13 to find y, then plug y into the second equation.

y= -3x+13

5x-2(-3x+13)=7

find x.

5x+6x-26=7

11x=33

x=3

now plug x into 3x+y=13(you could do it with the other equation too)

3(3)+y=13

y=13-9

y=4

The value of x and y is 3, and 4 respectively by the substitution method.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have a system of equations;

3x +y=13 ...(1)

5x-2y=7​ ...(2)

By using the substitution method.

[tex]\rm 5\cdot \dfrac{13-y}{3}-2y=7[/tex]

y = 4

Plug y = 4 in equation (1)

3x + 4 = 13

x = 3

Thus, the value of x and y is 3, and 4 respectively by the substitution method.

Answer:

3rd answer choice

Step-by-step explanation:

The problem says "no more than" so automatically the first and second answer choices are wrong

Now looking at the last choice, it subtracts 5, but 5 shouldn't be subtracted since all of Janet's purchases should be combined. So that just leaves the third choice

Answer:

3y+5 ≤ 17

Step-by-step explanation:

ok so we need she is buying a certain amount of markers but we don't know exactly how many so it would be 3y

we also know that she brought ONE notebook for 5 dollars which is why it would be 3y + 5

because the total amount will soon add up

now the reason it is ≤ 17

is because the symbol "≤" means less than or equal to

she did NOT spend MORE than 17 but we do not know if she spent exactly 17 or less.

Answer:

12 side polygon

Step-by-step explanation:

Interior angle of n side regular polygon: = ((n-2)x180)/n

((n-2)x180)/n = 150

(n-2)x180 = 150n

180n - 360 = 150n

30n = 360

n = 12

check: (12-2)x180/12 = 150

Answer:

The polygon has 12 sides (a dodecagon).

Step-by-step explanation:

Angles in a Regular Polygon

A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that each angle (in a regular polygon) measures

[tex]\displaystyle \frac{180(n-2)}{n}[/tex]

We are given the interior angle of 150°, thus:

[tex]\displaystyle \frac{180(n-2)}{n}=150[/tex]

Multiplying by n:

[tex]\displaystyle 180(n-2)=150n[/tex]

Operating

[tex]\displaystyle 180n-360=150n[/tex]

Rearranging and simplifying:

[tex]\displaystyle 180n-150n=360[/tex]

[tex]\displaystyle 30n=360[/tex]

[tex]n=360/30=12[/tex]

n = 12

The polygon has 12 sides (a dodecagon).

Answer:

a=9

Step-by-step explanation:

2/3 (a-18)=-6

a−18=−6×( 3/2)

a−18=−6×3/2

a−18= −18/2

a−18=−9

a=−9+18  

a=9

​

Answer:

A=9

Step-by-step explanation:

Simplify both sides of the equation.

2/3(a−18)=−6

(2/3)(a)+(2/3)(−18)=−6(Distribute)

2/3a+-12=-6

2/3a-12=-6

Add 12 to both sides.

2/3a−12+12=−6+12

2/3a=6

Multiply both sides by 3/2

(3/2)* (2/3a)= (3/2)* (6)

A=9

Answer:

CROSS JOIN  (/^\s*symmetric\s*difference\s*$/)

Step-by-step explanation:

Remember, in SQL (Structured Query Language) operations, we can use the CROSS JOIN function to take data from one row of a table in the database and join it with each row of another table.

In other words, the result of FULL OUTER JOIN minus the INNER JOIN of the data set would require a CROSS JOIN operation which would the two different rows into one row.

Answer:

Option A: 17,18,19 is the right answer.

Step-by-step explanation:

Let x be the first integer then the next two consecutive integers will be x+1, x+2

According to the given statement, the equation will be:

[tex]x + (x+1) + (x+2) = 54[/tex]

The equation is a linear equation in one variable, we have to solve the equation to get the values of integers

[tex]x+x+1+x+2 = 54\\3x+3 = 54\\3x = 54-3\\3x = 51\\\frac{3x}{3} = \frac{51}{3}\\x = 17[/tex]

Second integer = x+1 = 17+1 = 18

Third integer = x+2 = 17+2 = 19

The three integers are: 17,18 and 19

Hence,

Option A: 17,18,19 is the right answer.

Answer:

(0,6)

(1,5)

(2,4)

(3,3)

(4,2)

Step-by-step explanation:

To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.

Answer:

3.68 inches × 77.28 inches

Step-by-step explanation:

Given that,

The perimeter of a rectangle is 162 inches.

Let the width is b.

ATQ,

Length = 7 times than 3 times the width

l = 7(3b) = 21b ...(1)

The perimeter of a rectangle is given by :

P = 2(l+b)

Put all the values,

162 = 2(21b+b)

81 = 22b

b = 3.68 inches

Put the value of b in equation (1)

l = 21b

= 21 (3.68)

= 77.28 inches

Hence, the dimensions of the rectangle are 3.68 inches × 77.28 inches
