Can someone please help me with this question the instructions are to use a calculator to find the perimeter (the solid lines and curves) of each figure. The perimeter of each semicircle can be found by using the equation 1/2 pi d (the place where I put the words pi has the pi symbol, and d is just a variable. Also use 3.14 as pi, and the top part is cut off a little bit, but it still counts as a full semi circle. Please help me.

Answer:

Step-by-step explanation:

1) |1-(-3)| = |1+3| = 4

2) |2-(-3)| = |2+3| = 5

3) (base x height)/2 = (5 x 4)/2 = 10

Answer:

The volume of this shape is 41 inches sq. :)

Step-by-step explanation:

7 x 3 = 21

2 x 2 = 4/2 = 2

2 x 2 = 4/2 = 2

2 x 2 = 4/2 = 2

2 x 2 = 4/2 = 2

2 x 3 = 6

2 x 3 = 6

21 + 2 + 2 + 2 + 2 + 6 + 6 = 41

Answer:

8.75+7.45=16.2. 16.2 is equal to $16.20 so 48.00-16.20=31.8. Jonathan had $31.80 left.

are you sure this is math because it looks more like a english..

Step-by-step explanation:

Answer:

First combination: One $5 bill, one $1 bill, two quarters and one dime.

Second combination: One $5 bill, one $1 bill, two quarters and two nickles.

Step-by-step explanation:

I highly suggest reading it to make sure you understand it

Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60

So we have to work with $6.60

Now lets think of the obvious/easiest.

A $5 bill is going to be our best friend in this.

We have to do

6.60-5.00=x

(Don't freak out about x, it's just our place marker!!)

The reason we do 5.00 is because that's what $5 is.

So let's solve now.

6.60-5.00=1.60

So x=1.60

But you don't have to worry about x, I'm just explaining it from before.

So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.

1.60-1.00=0.60

So now we only have to figure out how to get 60 cents from any of the coins.

A quarter is 25 cents so lets use two of those

25+25=50

60=50=10

Lets recap on everything we've used so far.

We've used one $5 bill, one $1 bill, and two quarters.

Now we're going to add a dime to the mix.

A dime is worth 10 cents.

So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.

Now our second combination is going to be really easy.

We can use almost everything the exact same, we're only going to switch up the dime part.

1 dime = 2 nickles

Nickles are worth 5 cents

So we take out the dime and replace it with two nickles.

So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.

Answer:

Step-by-step explanation:

x^3+7x^2+5x^2+35x

= x^3+12x^2+35x

Answer:

x³ + 12x² + 35x

Step-by-step explanation:

"What is (x² + 5x) multiplied by (x + 7)?

First, we can convert this into an algebraic expression!

This can be written as:

(x² + 5x)(x + 7)

We can use the FOIL Method for multiplying binomials.

FOIL: First, Outer, Inner, Last

"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."

FOIL: First: x² × x

x² × x = x³

FOIL: Outer: x² × 7

x² × 7 = 7x²

FOIL: Inner: 5x × x

5x × x = 5x²

FOIL: Last: 5x × 7

5x × 7 = 35x

Add Everything Together!

x³ + 7x² + 5x² + 35x

Simplify:

x³ + 12x² + 35x

Answer:

$5,000

Step-by-step explanation:

Answer:

The correct answer is C) 11 | 2 = 112

Step-by-step explanation:

That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:

112, 112, 115, 118.

The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.

Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

Step-by-step explanation:

0.04

0.9

0.36

Answer:

Step-by-step explanation:

1/25   Dividing 1 by 25 on a calculator results in 0.04 (the decimal equivalent)

9/10   Dividing 9 by 10 on a calculator results in 0.9.

9/25  See 1/25, above.  Just multiply 0.04 by 9:  9/25 = 36/100 = 0.36

Answer:

$699

Step-by-step explanation:

90.87 * 5 = 454.35

454.35 = 65%

/65               /65

6.99 = 1%

*100        *100

$699 = 100%

Total Cost = $699

Answer:

544 cm^2

Step-by-step explanation:

You can see that the figure is made of 6 different rectangles, which would become the sides of the prism if it was 3D.

The top rectangle has a length of 16 cm and a width of 8 cm. 16 x 8 = 128 so this side has an area of 128 square cm

The one directly below that has the same length (16 cm) and a width of 6 cm. 16 x 6 = 96 so its area is 96 square cm

On either side of the previous one there is a 6 by 8 rectangle. 6 x 8 = 48. Remember, there are two sides with an area of 48 cm^2

Below that we have another 16 by 8 rectangle and then another 16 by 6 rectangle.

So your total surface area would be 128 + 96 + 48 +48 + 128 + 96

or 544 square cm

Answer:

B {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}

Step-by-step explanation:

Ima try to explain this in the process of elimination:

A isn't right since he only throws the ball 3 times

C isn't right, since he could catch it, miss, then catch again and would still match the criteria stated.

D Isn't right since he threw it 3 times, not twice

that only leaved B to be correct! Hope this helps!

Step-by-step explanation:

Simplifying

3x + -1s = r

Reorder the terms:

-1s + 3x = r

Solving

-1s + 3x = r

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-1s + 3x + -3x = r + -3x

Combine like terms: 3x + -3x = 0

-1s + 0 = r + -3x

-1s = r + -3x

Divide each side by '-1'.

s = -1r + 3x

Simplifying

s = -1r + 3x

Answer:

2.40$ dollars.

We find 20% of 3.00$, which is 0.6$ we then subtract that amount by the normal cost which is 3.00$, so we have an equation that looks like this 3.00$ - 0.6$ = 2.40$ dollars.

Answer:

Y= 5/3x + -9

Step-by-step explanation:

Well its

y=mx+b

m is slope

B is y intercept

To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.

Slope Is just

(y2-y1) / (x2-x1)

Answer:

y = 5/3x - 9

The equation for slope-intercept form would be y = mx + b.

Where y would be the total, m would be the slope, and b would be the y-intercept.

Answer:

$36.38

Step by step explanation:

First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.

This gives us $0.40.

To then find out fifteen percent of $40, you then times $0.40 by 15.

This gives us 6 dollars.

Now, to work out the discount, we take 6 from 40.

$40 - $6 = $34

Now we have to work out the tax.

Again, we have to work out what 1% of $34 is.

This gives us $0.34

Then times that by 7 to find 7%

0.34 x 7 = $2.38

Since this is tax we have to add instead of subtracting.

$34 + $2.38 = $36.38 as the final bill.
