Answer:6.3×(15÷3+6.8)-28.09

Step-by-step explanation: Hello!

6.3×15÷3±6.8-28.09

You should probably use addition instead of subtraction so let's try:

First try the expression 6.3×15÷3+6.8-28.09

You have to make a set of parentheses.  You should probably not include 6.3 in the parentheses so you can multiply whatever is in the parentheses by 6.3.  You should also probably not include -28.09 in the parentheses because you will make a negative number in the parentheses that won't be able to be made positive.  Try:

6.3×(15÷3+6.8)-28.09

6.3(5 + 6.8)-28.09

6.3(11.8)-28.09

74.34-28.09

=46.25

This is correct!

[tex]\huge\boxed{\sf V \approx 150.7\ in.\³}[/tex]

Step-by-step explanation:

Radius = r = 2 in.

Height = h = 12 in.

Answer: h ≥ 60

Step-by-step explanation:

≥ means more than or equal to

to be able to ride the roller coaster their height must be more than or equal to 60.

Answer: h ≥ 60

Step-by-step explanation:

h < 60 means that the height is less than 60

h  > 60 means that the height is more than 60

h ≥ 60 means that the height is 60 or more

h ≤ 60 means that the height is 60 or less

So the answer would be h ≥ 60 because the height is at least 60 or more

Answer:

x ≤2

Step-by-step explanation:

There is a closed circle at 2 and the line goes to the left.

The line going to the left means less than.  The closed circle means equal to

x ≤2

Answer:

x < 2

Step-by-step explanation:

Since 2 is a positive, larger than a negative the symbol is <

And since the it is a closed circle you have to underline the < to <

Answer: 2.55

Step-by-step explanation:

To find the diameter you divide the circumference by pi (3.14).

The formula is d=c/π

8/3.14 is 2.547... and when rounded would be 2.55 or 2.6 if rounded.

Answer: $30 on decorations, $65 on food, $80 on party hall rental, $30 on prizes, and $45 on invitations.

Step-by-step explanation:

Hello! You are told that she has spent $375.00.  You know she spent $40 on costumes, $30 on prizes, $65 on food, $45 on candy, $80 on party hall rental, $40 on music, and $45 on invitations.  You can fill what you know in for food, party hall rental, prizes, and invitations.  You still don't know how much Mary spent on decorations though.  To find this information out.  Add all of the amounts that you already know and subtract the total from 375 to find the remaining amount Mary spent for decorations.  30 + 65 + 45 + 80 + 40 + 40 + 45 = $345.  Subtract 345 from 375.  375 - 345 = 30.  Your final answer is she spent $30 on decorations.  Hope this helps you out! :)

1.5π

Step-by-step explanation:

Inner circle area = π

Outer circle area = 2.5π

The surface area of the top of the doughnut is 21[tex]\pi[/tex] sq inch.

Sector of a circle is like slice of a circular pizza. Its two straight edge's having an angle, and edge's length(the radius of the circle) are two needed factors for finding the area of that sector.

Since the whole circle with radius 'r' units have 360 degrees angle on center of the circle, and its area is

[tex]\pi r^2 \: \rm unit^2, thus, as the angle lessens, this area gets lessened. 360 degree = > \pi r^2 \: \rm unit^2 area1 degree = > \pi r^2 \: \rm unit^2/360 areax degree = > \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]

Thus, area of a sector with edge length 'r' units and interior angle 'x' degrees is given as:

[tex]A = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]

Given;

The diameter of inner dough=2inches

The diameter of outer dough=5inches

To find the surface area of doughnut

=surface area of outer dough - surface area of inner dough

= [tex]\pi[/tex]R^2-[tex]\pi[/tex]r^2

=25[tex]\pi[/tex]-4[tex]\pi[/tex]

=21[tex]\pi[/tex]

Therefore, the area will be 21[tex]\pi[/tex] sq inch.

Answer:

  y = 32 -2x

Step-by-step explanation:

You want an equation for the remaining community service Yuson must complete after x days if she does 2 hours per day and is half done after 8 days.

Yuson has completed (2 hr/day)·(8 day) = 16 hr of community service after 8 days. This is half the total required, so the initial amount required must be 2·16 = 32 hours.

After x days, 2x hours have been completed, reducing the amount remaining. Thus the amount remaining is ...

  y = 32 -2x . . . . . hours left after x days

Answer:

B. 20% increase

Explanation:

30 - 25 / |25| * 100%

5 / 25 * 100%

0.2 * 100%

20%

Answer:

To figure out the total cost of the meal, you can use the following formula:

Total cost = (Tip + Tax) / (1 - (Tip % + Tax %))

In this case, the tax is 4% and the tip is 15%, so we can plug in the values to get:

Total cost = (1.95) / (1 - (0.15 + 0.04))

Now we can solve for the total cost:

Total cost = 1.95 / (1 - 0.19) = 1.95 / 0.81 = 2.40625$

So the total cost of the meal was $2.40625, including tax and the tip left by the customer.

When plotting fractions on a number line, we need to figure out how much each tick mark is. See the photo attached for how to plot 2 1/3, –5/6, and –3 1/2 on the number line.

On a number line,

This number line also has negative numbers. Each tick is still worth the same on the entire number line, but leftward of 0, the numbers become negative.

The vertical markings on the number line are called tick marks.

To get from one whole number to the next whole number on the number line, we have to count 6 tick marks. This means that each tick is 1/6.

The dot will be between 2 and 3.

First, find 2.

[tex]\frac{1}{3} =\frac{1*2}{3*2}=\frac{2}{6}[/tex]       Since 1/3 = 2/6, we then move right (get bigger) by 2 ticks.

See the photo below for the plotted dot. 2 1/3 is in red.

The dot will be between -1 and 0.

Start at 0. Then, move left (get smaller) by 5 ticks.

See the photo below for the plotted dot. – 5/6 is in green.

The dot will be halfway between –3 and –4.

First, find –3. Then, move left (get smaller) by 3 ticks.

See the photo below for the plotted dot. –3 1/2 is in blue.

Answer:

Cubes needed to fill Prism 6: 116

The volume of Prism 6: 125

Step-by-step explanation:

First, multiply the length by the width. We can find these measurements by looking at the bottom diagonal line of the cubes.

Count how many sides are facing the front on the lowest side.

There are 5 squares facing forwards that are inside the Prism. Therefore the width/length is 5 cubic units.

Now count how many cubes it takes to go from the front side to the backside, or how many squares are facing the right. Remember this is a 3-dimensional object.

5 squares are facing the right, each belonging to the 5 cubes on the bottom of the prism.

Now count how many cubes are stacking. There are 5 cubes in the tower.

To find the volume, multiply all the measurements together.

Volume = Length x Height x Width (5 x 5 x 5)

Now to find how many cubes are needed to fill the prism, count how many cubes are already inside Prism 6.

Once you've found out how much the volume is, subtract the number of cubes inside the prism(9) from the volume(125).

125 - 9 = 116 cubes are needed to fill Prism 6.
