need help with this confusing

Answer:

259

Step-by-step explanation:

[] To round, you look to the number placed right of the value you are rounding. If it is greater than or equal to 5, you round up. If it is less than or equal to 4, the number stays the same.

[] The whole number is the number before the decimal, we will round it off at the ones place.

[tex]258.68\\258.[6]8\\\\6 \geq 5\\\\259[/tex]

Answer:

259.

Step-by-step explanation:

All we need to do is,

Look at the number after the decimal place, Check to see if it is greater or less than 5.

Numbers that are less than 5 will be decreased and numbers that are 5 and over will be increased. We have a 6 after the decimal point so we are going to round up.

258.68, The number just before the decimal point is 8. One more than 8 is 9 so our answer will be 259 as a whole number with no decimals!

Hope that helps. x

Answer:

Each muffin= 1.5; Each quart of milk= 3

Step-by-step explanation:

Let m represent muffins and q quarts of milk, so

8m+2q=18

3m+1q=7.50

*solve*

3m+1q=7.5

    -1q    -1q

3m=-1q+7.5

/3     /3   /3

m=-1/3q+2.5

*replace for m*

8(-1/3q+2.5)+2q=18

-2 2/3q+20+2q=18

-2/3q+20=18

         -20 -20

-2/3q=-2

/-2/3  /-2/3

q=3

*replace to find m*

3m+1(3)=7.50

3m+3=7.5

      -3  -3

3m=4.5

/3     /3

m=1.5

*replace to verify*

8m+2q=18

8(1.5)+2(3)=18

12+6=18

18=18

3m+1q=7.50

3(1.5)+1(3)=7.5

4.5+3=7.5

7.5=7.5

Answer:

  106°

Step-by-step explanation:

The acute angles in a right triangle are complementary, so ...

  ∠C = 90° -46° = 44°

With respect to triangle CDE, exterior angle ADE is the sum of remote interior angles C and CED.

  ∠CDE = 44° +62° = 106°

Answer:

Step-by-step explanation:

We know that it costs 3.50 dollars for a gallon of gas, so we can write the total cost as an expression.

Expression: c= 3.50g

To find the total cost for 5 gallons, plug 5 into the variable, g.

c= 3.50g

c= 3.50(5)

c= 17.5 dollars

Answer:

x-intercept=8

y-intercept=2

Step-by-step explanation:

Answer:

x-intercept: 8

y-intercept: -2

Step-by-step explanation:

To find the x-intercept, we will substitute 0 for y, and to find the y-intercept, we'll do the opposite, substitute 0 for x.

-x + 4(0) = -8

-x = -8

x = 8

x-intercept: 8

-(0) + 4y = -8

4y = -8

y = -2

y-intercept: -2

Step-by-step explanation:

Because the panthers got 6 less and the tigers got 22…

b+6 would make 22 (panthers plus 6 makes tigers)

22-b would also be 6 because 6+b makes 22, so subtracting b from 22 makes 6

Answer:

  15.62

Step-by-step explanation:

The length XY is found from the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((4 -(-8))² +(-6 -4)²) = √(12² +(-10)²) = √244

  d ≈ 15.62 . . . units

The length of XY is approximately 15.62 units.

Answer:

0.14

Step-by-step explanation:

In total you have 1.00% chance of picking something. If you have a 0.54% chance of picking jeans and a 0.32% chance of choosing khaki. You have a 0.14% chance at choosing black pants.

0.54+0.32=0.86

1.00-0.86=0.14

Answer:

so the answer is 50%

Step-by-step explanation:The interquartile range is the difference between the upper quartile and the lower quartile. In example 1, the IQR = Q3 – Q1 = 87 - 52 = 35. The IQR is a very useful measurement. It is useful because it is less influenced by extreme values as it limits the range to the middle 50% of the values.

Based on the calculations, Kirk bought 2.4 bags of popcorn and 7.2 sodas.

Given the following data:

a. To write a system of equations that models this scenario:

A system of equations can be defined as an algebraic equation of the first order that has two (2) variables with each of its term having an exponent of one (1).

[tex]4.5s+1.5p=36[/tex]    ...equation 1.

Translating the word problem into an algebraic expression, we have;

Three times as many bags of popcorn as sodas:

[tex]3p=s[/tex]   ...equation 2.

b. To determine how many of each item Kirk bought:

Substituting eqn. 2 into eqn. 1, we have:

[tex]4.5(3p)+1.5p=36\\\\13.5p+1.5p=36\\\\15p=36\\\\p=\frac{36}{15} [/tex]

p = 2.4 bags of popcorn

For soda:

[tex]s=3p\\ \\ s=3 \times 2.4[/tex]

s = 7.2 sodas.

Answer:

  (d)  (7, -5)

Step-by-step explanation:

The x-coordinate is listed first in an ordered pair. It is found on the horizontal scale. The point is on the grid line halfway between 6 and 8, so is presumed to have an x-coordinate of 7.

The y-coordinate is listed second in an ordered pair. It is found on the vertical scale. The point is on the grid line halfway between -4 and -6, so is presumed to have a y-coordinate of -5.

The coordinates of point A are (x, y) = (7, -5).

Additional comment

As in the case here, you will often run across graphs that don't have markings on every grid line You are expected to be able to figure out the value of a grid line based on the spacing of the marked lines.

It is a good idea to get familiar with reading coordinates of a point on a graph, as you will be doing it a lot.

The three equations that pass through the points (–4, –16) and (5, 2) are y - 2 = 2(x - 5), y = 2x - 8 and y + 16 = 2(x+4)

The equation of a line in point-slope form is expressed as:

y - y1 = m(x-x1)

Given the coordinate points  (–4, –16) and (5, 2)

Get the slope

[tex]m =\frac{2+16}{5+4}\\ m =\frac{18}{9}\\ m = 2[/tex]

Substitute m= 2 and (5, 2) into the equation to have:

y - 2 = 2(x - 5)

Expand

y - 2 = 2x - 10

y = 2x - 8

ALso using the coordinate point (-4, -16)

y - (-16) = 2(x-(-4))

y + 16 = 2(x+4)

Hence the three equations that pass through the points (–4, –16) and (5, 2) are y - 2 = 2(x - 5), y = 2x - 8 and y + 16 = 2(x+4)

27:9 . To simply/reduce, divide both numbers by the same number.

27/9 = 3

9/9 = 1

so, 3:1 is one of the correct choices.

27/3 = 9

9/3 = 3

so, 9:3 is another correct choice
