Answer:

261 km

Step-by-step explanation:

given,s=constant

d1/T1=d2/T2

d1=90km,t1=50 min

d2=? ,t2=(120+25)min

=145min

therefore,d2=(90×145)/50

=261 km

Answer:

0.10

Step-by-step explanation:

Answer: 40

Step-by-step explanation:

Given

Radius of disc [tex]r=4\ cm[/tex]

The dimension of the sheet is [tex]84\times 24\ cm^2[/tex]

Area of a single disc

[tex]\Rightarrow a=\pi r^2=\frac{22}{7}\times 4^2\\\\\Rightarrow a=\frac{352}{7}\ cm^2[/tex]

Area of sheet

[tex]\Rightarrow A=84\times 24=2016\ cm^2[/tex]

No. of discs that can be cut off the sheet are

[tex]\Rightarrow n=\dfrac{A}{a}=\dfrac{2016}{\frac{352}{7}}=\dfrac{2016\times7}{352}\\\Rightarrow n\approx 40[/tex]

The total area of the disc is

[tex]\Rightarrow na=40\times\frac{352}{7}=2011.428\ cm^2[/tex]

Sheet wasted

[tex]\Rightarrow A-na=2016-2011.428=4.57\ cm^2[/tex]

Answer: 1/8

Step-by-step explanation: The sample space are all of the different outcomes an event can lead to. The H and T combinations at the bottom are all of the different outcomes. I think the probability of getting 3 tails for the coins (or TTT) is 1/8. This is because there are 24 total outcomes (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT). There is 3/24 TTTs (also, 1/8 if you count the groups/simplify). Therefore, it is 1/8. Hope this helps!

Answer:

Step-by-step explanation:

tan Ф = opposite side  divided by the adjacent side    

tan Ф = opp/adj    in your problem Ф is x

tan x = 4/9        

x = arctan (4/9)      on your calculator arctan is might look like inverse tan

                       or you might have to use the 2nd (second) button and then tan

x = inverse tan (0.44444 repeating)     try it on your own calculator

 = 23.962488974578183                     rounds up to 24.0

 = 24.0    

Answer:

Step-by-step explanation:

It cost $0.46 for 1 kg of peaches $.46/kg

It cost $12.6 for 1 m² of flooring tiles $12.6/1 m² of flooring tiles

It cost $1.6 for 1 L bottle of juice $1.6/L

dont know shrimp

The unit costs are:

(a) $1.85 for 4 kg  peaches= $0.4625 per Kg

(b) $16.99 for a 454 g package cooked shrimp= $37.423 per Kg

(c) $2.99 for a 1.89 L bottle juice= $1.58 per L

(d) $283.28 for 22.5 m2 flooring tiles= $12.6 per m²

In order to find the unit value of a quantity then divide the total cost by the quantity to get the unit price.

Unit price = total cost/ total number of quantity

here given

(a) $1.85 for 4 kg peaches

unit cost =  total cost/ total number of quantity

= $1.85/4 Kg

=$0.4625 per Kg

(b)  $16.99 for a 454 g package cooked shrimp

unit cost =  total cost/ total number of quantity

= $16.99/454g

=$0.037 per gram

=$37.423 per Kg

(c) $2.99 for a 1.89 L bottle juice

unit cost =  total cost/ total number of quantity

= $2.99/1.89L

=$1.58 per L

(d)  $283.28 for 22.5 m2 flooring tiles

unit cost =  total cost/ total number of quantity

=$283.28/22.5m²

=$12.6 per m²

Therefore the final unit costs are:

(a) $1.85 for 4 kg peaches= $0.4625 per Kg

(b) $16.99 for a 454 g package cooked shrimp= $37.423 per Kg

(c) $2.99 for a 1.89 L bottle juice= $1.58 per L

(d) $283.28 for 22.5 m2 flooring tiles= $12.6 per m²

Answer:

5^43

Step-by-step explanation:

[5² . 5² . 5³. 125 . 125³ ]³ : [25² . 5² . 5]² =

= [5² . 5² . 5³. 5³ . (5³)³ ]³ : [(5²)² . 5² . 5]²

= [5² . 5² . 5³. 5³ . 5^9 ]³ : [5^4 . 5² . 5]²

= [5^19]³ : [5^7]²

= 5^57 : 5^14

Answer:

This (x - 5) represents the length of the rectangle.

Step-by-step explanation:

The formula for the area of a rectangle of length L and width W is A = L * W.

Here, the width is x - 4 and the area is x^2 + x - 20.  Dividing the width (x - 4) into the area results in an expression for the length:

x - 4  /   x^2 + x - 20

Let's use synthetic division here.  It's a little faster than long division.

If the divisor in long division is x - 4, we know immediately that the divisor in synthetic division is 4:

4   /   1    1    -20

              4     20

    --------------------

         1     5     0

This synthetic division results in a remainder of 0.  This tells us that 4 (or the corresponding (x - 4) is indeed a root of the polynomial x^2 + x - 20, and so *(x - 4) is a factor.  From the coefficients 1 and 5 we can construct the other factor:  (x - 5).  This (x - 5) represents the length of the rectangle.

Answer:

x = 2

Step-by-step explanation:

Using the rule of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

[tex](2)^{3x}[/tex] = [tex]2^{3x}[/tex] and 8 = (2³ )² = [tex]2^{6}[/tex] , so

[tex]2^{3x}[/tex] = [tex]2^{6}[/tex]

Since the bases on both sides are equal, both 2, equate the exponents

3x = 6 ( divide both sides by 3 )

x = 2

Answer:

106 in²

Step-by-step explanation:

Given that :

Davindra made a paper box that is 8 in. Long, 5 in. Wide, and 1 in. High.

Using the relation :

SA=2lw+2lh+2hw

Surface area :

2(lw + lh + hw)

l = 8 ; w = 5 ; h = 1

Surface area :

2(8*5 + 8*1 + 1*5)

Surface area :

2(40 + 8 + 5)

Answer:

58=3.50x=2

Step-by-step explanation:

Answer:

Let the missing angles be x, 2x, 3x.

X + 130° + 2x + 3x = 180°. (sum of angles is 180°)

6x + 130° = 180°

6x = 180°- 130°

6x = 50°

x = 50° ÷ 6

x = 8°

:. 2x = 8 × 2

16°

:. 3x = 8 × 3

24°

Step-by-step explanation:

Answer:

5x^2 + 20x + 20 = 0

12+ 6x +9= 0​

Step-by-step explanation:

5x^2 + 20x + 20 = 0  /5             12 + 6x + 9 = 0        

x^2 + 4x + 4 = 0                          6x = -9-12
