Answer:

%17.70

Step-by-step explanation:

18% of $15 is $2.70

$15+$2.70=$17.70

Answer:

Tip: $2.70

Total: $17.70

Step-by-step explanation:

To find the tip amount, we have to find 18% of 15.

To find the total amount, we add the tip amount to the cost.

Check the picture below.

so, the figure is really one big square, a 10x10, with four triangles in it, now, if we just get the area of the square, well 10x10 is just 100 in², and then get the areas of those three triangles, the yellow, purple and orange ones, and subtract their area from that of the larger square, what's leftover is the shaded triangle.  By subtracting the areas from the larger area, we're in essence making a big hole in the larger area, and what's leftover is what was never subtracted.

Answer:

B

Step-by-step explanation:

the perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

P = 2(3[tex]\sqrt{15}[/tex] ) + 2([tex]\sqrt{15}[/tex] ) ← distribute both parenthesis )

   = 6[tex]\sqrt{15}[/tex] + 2[tex]\sqrt{15}[/tex]

Answer:

19 + 2c

Step-by-step explanation:

19 is increasing two times Chau's height, (c), which gives you 19 plus twice c, (2c).

Answer:

Yes, it is a function.

Step-by-step explanation:

We can see that using the vertical line test, none of the x points cross the line more than once, that means that it is a function, since it passes the vertical line test.

Answer:

x=7 and y=4

Step-by-step explanation:

I will use the elimination method:

Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:

3x + y =25
+     +     +

2x - y = 10

Simplify:

5x=35

Divide both sides by 5:

5x÷5=35÷5

Simplify:

x=7

Substitute this into either equation 1 or 2 ( I chose 1):

3(7) + y = 25

21 + y = 25

Subtract 21 from both sides and simplify to get y:

21+y-21=25-21

y=4

Therefore x=7 and y=4

Answer:

26.93

Step-by-step explanation:

The right polygon is the first one scaled down by 1.33 so we can multiply the values on the 2nd one by 1.33 to get the first one.

y+1 = 21*1.33

y+1 =27.93

y=26.93

Answer:

1 19/21

Step-by-step explanation:

1. Convert both mixed numbers into improper fractions:

2. Now we are doing 8/3 ÷ 7/5. We can use KCF to divide these fractions:

8/3 ÷ 7/5 → 8/3 × 5/7 = 40/21

3. Finally, convert 40/21 back into a mixed number: 1 19/21

Step-by-step explanation:

1. First, isolate the x. Subtract 2.9 from both sides of the equation to get x = 4.46

Answer: s = -4

Step-by-step explanation:

s/4 + 15 = 14

We can subtract 15 from both sides:

s/4 = -1

We can multiply both sides by 4:

s = -4

Y=(5×6)-12

y= 30-12

Y=118

Answer:

C

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )

x² = 20 × (20 + 36) = 20 × 56 = 1120 ( take square root of both sides )

x = [tex]\sqrt{1120}[/tex] = [tex]\sqrt{16(70)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{70}[/tex] = 4[tex]\sqrt{70}[/tex]

Answer:

W=12 cm.

Step-by-step explanation:

If the total area is 180 sq. cm., and you multiply length times width to find area, this time it is inversed. So you do 180/15=12

Answer:

12 cm

Step-by-step explanation:

The area of a rectangle = length × width

We know that the length is 15 cm and the area is 180 cm² so we can substitute this into the equation:

180 cm² = 15 cm × width

Finally, we can divide both sides by 15 to find the width:

width = 180 ÷ 15

width = 12 cm

The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches

where

l = length

w = width

h = height

Therefore,

l = 18 inches

w = 6 1 / 2  = 13 / 2 inches

h  =?

v = 292 1 / 2  = 585 / 2

Therefore,

h = v / lw

h = 585 / 2 × 1 / 18 × 2 / 13

h = 585 / 234

h = 2.5 inches

Using it's concept, it is found that there is a 0.4 = 40% experimental probability of the next player drawing a white token.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In an experimental probability, these number of outcomes are taken from previous trials.

In this problem, in the first 10 draws, 4 resulted in the player drawing a white token, hence:

p = 4/10 = 0.4.

There is a 0.4 = 40% experimental probability of the next player drawing a white token.
