This is very very very confusing!!!! Anyone know 8th grade stuff?


Is this relation a function? _____ Explain how you know.

Answer:

( a= 5/2 )

Step-by-step explanation:

Divide both sides by the same factor

           10=4a

         10/4    4a/4

Divide the numbers

Cancel terms that are in both the numerator and denominator

Move the variable to the left

      ( a= 5/2)

Step-by-step explanation:

[tex] = 1 \frac{1}{5} \div \frac{1}{10} \\ [/tex]

[tex] = \frac{1 \times 5 + 1}{5} \div \frac{1}{10} \\ [/tex]

[tex] = \frac{6}{5} \times \frac{10}{1} \\ [/tex]

[tex] = \frac{60}{5} \\ [/tex]

[tex] =\frac{60 \div 5}{5 \div 5} \\ [/tex]

[tex] =\frac{12}{1} \\ [/tex]

Answer:

y = -6.17

Step-by-step explanation:

6 (2y+7) = -20

12y + 54 = -20

12y = -20 - 54

12y = -74

y = -6.17 (3sf)

Answer:

equation: -3 + y = -8

solution y: -5

Answer:

The top right flower pot can't hold all the soil in the bag.

Step-by-step explanation:

Do the volume of each flower pot

Top left flower pot = 1200 cubic inches

Top right flower pot = 640 cubic inches

Bottom left flower pot = 1000 cubic inches

Bottom right flower pot = 1000 cubic inches

The top right flower pot is the only flower pot with a volume less than 924 cubic inches.

Answer:

56.55mm

Step-by-step explanation:

circumference = 2r*π

9mm*2=18

circumference = 18π

18π=56.5487

18π=56.55

200.96 cm

Since we don't have the radius, we have to find it.

What you gave me is the diameter which is 16 (cm) I suppose.

Radius is half the diameter. Therefore we can divide the diameter by 2 to find the radius.

[tex]16[/tex] ÷ [tex]2=8[/tex]

This is our radius.

Plug this into the area formula.

[tex]A=\pi r^2[/tex]

[tex]A=(3.14)(8)^2[/tex]

[tex]A=200.96cm[/tex]

Answer:

2-(5x6)

Step-by-step explanation:

First you need to find the product of 5 and 6 so that would be 5x6. Then, you need to take that from 2, meaning you subtract that from 2.You would then get 2-(5x6)

Answer:

lowest value-0

lower quartile(or first quartile)-1.25

median-4.25

upper quartile-6.75

highest value-7

Step-by-step explanation:

lowest value=is the lowest number of a set

lower quartile(first quartile)=the number between the median and th   minimum or if there is a  even amount of values you find the mean of the values between the minimum and maximum

median=the middle number of a set

upper quartile(third quartile)=the middle number between the median and the maximum.

highest value(maximum)=the highest number in the set

Answer:

Lowest Value = 0

Lower Quartile = 1.5

Median = 4.5

Lower Quartile = 6.5

Highest Value = 7

Step-by-step explanation:

Given values:  

0, 1, 2, 3, 6, 6, 7, 7

Before determining the quartiles, place the values of the data set in order of size.

To find the position of the lower quartile (Q1) first work out n/4 (where n is the number of data values in the set).

If n/4 is a whole number, then the lower quartile is halfway between the values in this position and the position above.

⇒ 8/4 = 2, so the Lower Quartile is halfway between the 2nd and 3rd values.

⇒ Lower Quartile = 1.5

The median is the value in the middle of the data set when all the data values are placed in order of size.

To find the position of the median (Q2) first work out n/2.

If n/2 is a whole number, then the median is halfway between the values in this position and the position above.

⇒ Median = 4.5

To find the position of the upper quartile (Q3) first work out 3n/4 (where n is the number of data values in the set).

If 3n/4 is a whole number, then the lower quartile is halfway between the values in this position and the position above.

⇒ (3 x 8)/4 = 6, so the Lower Quartile is halfway between the 6th and 7th values.

⇒ Lower Quartile = 1.5

The lowest value is the smallest value in the data set = 0

The highest value is the largest value in the data set = 7

Answer:A. y ≥ 2

Step-by-step explanation:

First the line is solid, a complete line not dotted so the inequality sign to use is : ≥  or ≤

The points have their y-coordinate vale as 2, (−5, 2) and (3, 2), this means the line crosses the y-axis at y=2 but because the shaded part is above this line, then the correct inequality will be :

y ≥ 2

Answer:

22 km

Step-by-step explanation:

There is no mention about the triangle, but this can only be solved if the triangles are similar.

I assume the triangles are similar, so the lengths of corresponding sides are proprtional.

PR/TR = PQ/ST

24/33 = 16/ST

8/11 = 16/ST

1/11 = 2/ST

ST = 22

Answer: 22 km

Answer: D. 61 in²

Step-by-step explanation:

     This problem is asking for us to solve the area of the given circle. We will use the formula and solve.

     Please note that the formula asks for the radius and 9 in is the diameter. Since the radius is half the diameter, we will divide 9 in by 2 for a radius of 4.5 in.

     A = πr²

     A = π(4.5 in)²

     A ≈ 63.62 in²

     The closest option they give to solve this problem is D. 61 in²

          About 61 in² of pie crust is needed to cover the top of the pie.

Answer:

3 outfits with $3.92 as change

Step-by-step explanation:

The inequality represents the maximum number of outfits Alexa can purchase while staying within her budget is 520 ≥ 47.20o + 372.92.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

As per the given,

Bicycle cost = $342.82

4 bicycle reflectors cost = 4 × 3.90 = $15.6

Gloves cost = $14.51

Cost of "o" biking outfit = 47.72o.

Total cost ≤ Budget.

342.82 + 15.6 + 14.51 + 47.72o ≤ 520

372.92 + 47.20 o ≤ 520

520 ≥ 47.20o + 372.92

Hence "The inequality represents the maximum number of outfits Alexa can purchase while staying within her budget is 520 ≥ 47.20o + 372.92".

Answer:

[tex]\huge\boxed{\sf w = -14}[/tex]

Step-by-step explanation:

Given Equation:

6 + w = -8

Subtract 6 to both sides

w = -8 - 6

w = -14

[tex]\rule[225]{225}{2}[/tex]

Answer:

w = -14

Step-by-step explanation:

6 + w = -8

move 6 to the other side of the = sign

to do that you must subtract from both sides (of the equal sign) it since it is a positive number

6 + w = -8

-6          -6

this makes the 6 cancel out

-8 - 6 = -14

w = -14

your answer is -14
