Answer: 20.6

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

As they are similar corresponding sides are in the same proportion so

3/2 = BC/3

2BC = 3*3

2BC = 9

BC = 4.5.

3/2 = 5/DF

3DF = 2*5

DF = 2*5 / 3

= 3.33...

Perimeter of ABC = 3 + 4.5 + 5 = 12.5.

Perimeter of DEF =  2 + 3 + 3.33.. = 8.33...

Answer:

BC = 4.5 cm

DF = 10/3 cm

Step-by-step explanation:

Corresponding sides of similar triangles are in same ratio

[tex]\frac{BC}{EF}=\frac{AB}{DE}\\\\\frac{BC}{3} =\frac{3}{2}\\\\BC = \frac{3}{2}*3\\\\BC = \frac{9}{2}\\\\BC = 4.5 cm[/tex]

[tex]\frac{DF}{AC}=\frac{DE}{AB}\\\\\frac{DF}{5}=\frac{2}{3}\\\\DF = \frac{2}{3}*5\\\\DF = \frac{10}{3}[/tex]

Perimeter of ΔABC = 3 + 5 +4.5 = 12.5cm

Perimeter of ΔDEF = 2 + 3 + 3.3 = 8.3 cm

Answer:

45 meters

Step-by-step explanation:

so if i divided 9  by 3 it's 3 meters per sec then i times 15 by 3 equals 45

Answer:

Step-by-step explanation:

Here we can see

Arc YZ = Arc XZ

So we know that equal arcs form equal chords , Then

Chord YZ = Chord XZ

8x - 5 = 6x + 10

8x - 6x = 10 + 5

2x = 15

x = 7.5

Answer: [tex]\$107.82[/tex]

Step-by-step explanation:

Given

The cost of paint is [tex]\$29.95\text{per gallon}[/tex]

Nikki need [tex]3.6[/tex] gallons of paint

So, the cost of the paint is the product of the rate and volume of paint

Put the values

[tex]\Rightarrow 3.6\times 29.95=\$107.82[/tex]

Answer:

(–8, 1), (8, –8)

Step-by-step explanation:

Answer:

(-8, 1), (8, -8) has a negative slope

Step-by-step explanation:

1). y2 - y1 / x2 - x1

7 - 9 / 5 - 6

= 2

2). y2 - y1 / x2 - x1

6 - (-2) / 3 - (-9)

= 2/3

3). y2 - y1 / x2 - x1

-8 - 1 / 8 - (-8)

-9/16

4). y2 - y1 / x2 - x1

-9 - (-8) / -1 - 2

= 1/3

Recall the double-angle identity,

sin²(x) = (1 - cos(2x)) / 2

Now if sin(12°) = k, then

k ² = sin²(12°) = (1 - cos(24°)) / 2

→   cos(24°) = 1 - 2k ²

Answer:

.1km

Step-by-step explanation:

The tractor can move .01 km in a second so 10 times .01 is .1

so the tractor can move .1km every 10 seconds

1 hour = 3600 seconds

10 seconds is 10/3600 = 1/360 of an hour

36 km per hour x 1/360 of an hour = 0.1 km (100 meters)

Answer:

D

Step-by-step explanation:

Decimal = "and"

2 decimal places = "hundredths"

The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.

here, given that,

Round 245,675 to the nearest hundred thousand

we know,

Anything at or above 50 gets rounded up.

49 and below gets rounded down.

so, we get,

here, to the nearest hundred thousand means 675 > 500

so, it will be 5,675 => 6000

we have,

Rounding off 245,675 to the nearest hundred thousand is:

246000

Hence, The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.

#SPJ2

Answer:

0.45

Explanation:

the total probability of the spinner landing on red, blue or green is 0.20 + 0.12 + 0.08 = 0.40. thus, the remaining probability of the spinner landing on orange or pink is 1 - 0.40 = 0.60.

since the probability that the spinner will land on orange is three times that of pink, we can divide 0.60 by 3 + 1 to find the probability of it landing on pink:

0.60 ÷ 4 = 0.15

now, we can multiple this by 3 to find the probability that the spinner will land on orange:

0.15 × 3 = 0.45

To begin solving for the total cost of the paint that Ariana needs to buy, we first need to calculate the size of the walls and the ceiling that she is going to paint.

We begin by finding the size for the walls.

We use the formula  to find the area of each wall.

We know that the walls are 10-foot squares.

10 x 10 = 100 Square Feet

Each wall will have an area of 100 square feet each, we know that there are 4 walls in the shed.

100 x 4 = 400 Square Feet of walls to paint total.

Now we know that the ceiling will have the same area as the walls.

10 x 10 = 100 Square Feet of ceiling to paint.

Now Ariana goes to the store and finds that a gallon of paint cover 350 square feet. Ariana needs to paint a total of 400 square feet of wall.

400 - 350 = 50 Square Feet remains.

We know that she needs to buy the paint in gallons, so this leaves Ariana with purchasing 2 gallons of Blue paint.

Now Ariana also wants to paint the ceiling white. We know that 1 gallon of White paint is more than enough to cover the ceiling, but she still needs to buy the gallon of paint.

Now we add up all the prices of the 3 gallons of paint.

$26.98 x 2 = $53.96 for Blue Paint

$26.98 x 1 = $26.98 for White Paint

Total cost = $80.94.

Now we know that the sales tax is 5.5% of the total price.

$80.94 x 0.055

Sales Tax = $4.45

Now we simply add the total cost to the sales tax.

$80.94 + 4.45

Total cost with sales tax = $85.39

Answer:

$692.72

Step-by-step explanation:

Given data

The total area of tile = 260 squared feet

cost per squared foot of tile= $2.49

Hence the total for 260 squared feet cost will be

=260*2.49

=$647.4

Let us find the amount of 7% Tax

=7/100*647.4

=0.07*647.4

=$45.318

Hence the amount spent in all is

=45.318+647.4

=$692.72
