The blue shape is a dilation of the black shape. What is the scale factor of the dilation?

Answer:

Kindly check explanation

Step-by-step explanation:

Let :

Original commute time = x

Commute time due to road construction = 150% of original commute time

Hence, commute time due to road construction :

(150 / 100) * x

0.15x

Hence, the implication of the road construction in progress means that it will now take additional half of the usual time it takes them on a Monday morning.

For instance, an individual whose usu commute time is 10 minutes in the morning will now take :

1.5x = 1.5(10) = 15 minutes commute time on a Monday morning.

Answer:

21.74 But if it tells you to round I would round to 21 lbs

Step-by-step explanation:

its basically just a ratio of 92 to 20

92/20=4.6

92-20=72% the amount that is lost

so given that the plum is 100 lbs we know that 72% is depleted

(72/92 = .78)X100= 78 lbs depleted

Lastly 100-78 =22 for the remaining weight of the prunes.

Answer: 640 students.

Step-by-step explanation:

given data:

number of student chosen to attend by the mayor = 160

amount this student represents of the total population = [tex]\frac{1}{4}[/tex]

solution:

since [tex]\frac{1}{4}[/tex] was chosen which is 160 this means that [tex]\frac{1}{4} is \geq 160[/tex]

therefore;

[tex]\frac{1}{4} = 160\\[/tex]

multiply both sides by 4

[tex]\frac{1}{4} . 4 = 160 .4\\= 640[/tex]

the least number of students that attend melvins school is 640.

Answer:

60

Step-by-step explanation:

Answer:

[tex]\dfrac{9}{25}[/tex]

Step-by-step explanation:

Given that the bag contains black and red marbles.

Number of black marbles in the bag = 2

Number of red marbles in the bag = 3

Total number of marbles in the bag = Number of black marbles + Number of red marbles = 2 + 3 = 5

Let us have a look at the formula for probability of an event E, which can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

[tex]P(\text{First red marble}) = \dfrac{\text{Number of red marbles}}{\text{Total number of marbles}} = \dfrac{3}{5 }[/tex]

Now, the marble chosen at first is replaced.

Therefore, the count remains the same.

[tex]P(\text{Second red marble}) = \dfrac{\text{Number of red marbles}}{\text{Total number of marbles}} = \dfrac{3}{5}[/tex]

Now, the required probability can be found as:

[tex]P(\text{First red marble})\times P(\text{Second red marble}) = \dfrac{3}{5}\times \dfrac{3}{5} = \bold{\dfrac{9}{25} }[/tex]

Step-by-step explanation:

Time interval 6:53 a.m to 8:53 a.m, the average rate of change per hour the greatest.

Given,  

Time          Temperature (°F)  

5:53 a.m.       60.1

6:53 a.m.       60.1

8:53 a.m.       66.9

11:53 a.m        75.2

3:53 p.m.        78.1

From 5:53 a.m. to 6:53 a.m. the temperature is constant. So average rate of change per hour is 0.

From 6:53 a.m to 8:53 a.m. the temperature is increasing from 60.1 to 66.9 or 6.8 in 2 hours . So average rate of change per hour is [tex]\frac{6.8}{2} =3.4[/tex].

From 8:53 a.m. to 11:53 a.m the temperature is again increasing from 66.9 to 75.2 or 8.3 in 3 hours. So average rate of change per hour is [tex]\frac{8.3}{3} =2.76[/tex].

From 11:53 a.m to 3:53 p.m. the temperature is again increasing from 75.2 to 78.1 or 2.9 in 4 hours. So average rate of change per hour is [tex]\frac{2.9}{4}=0.725[/tex].

Now clearly from the above points time interval 6:53 a.m to 8:53 a.m, the average rate of change per hour the greatest.

Answer:

The equation is 0.5x - 5= y

Answer: (5,11)

Step-by-step explanation:

Answer:

k = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The equation of proportionality is

y = kx ← k is the constant of proportionality

To find k use any coordinate point lying on the graph

Using (12, 6 ), then

6 = 12k ( divide both sides by 12 )

k = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

9*364 - 9*125 - 9*39 = 1,800

Step-by-step explanation:

Mental Calculation

If we detect known patterns in the calculations, we could easily give their results without the use of calculators.

We are given the expression to evaluate:

9*364 - 9*125 - 9*39

The first thing to note is the 9 is a common factor of all terms, thus we take it out:

9*(364 - 125 - 39)

The negative numbers can be easily added

     125

+     39

------------

     164

Now our expression is much easier:

9*(364 - 164)

The subtraction of 364-164 is 200, thus the result of the operations is:

9*200. We only need to recall 9*2=18 and add two zeros to get 1,800, thus:

9*364 - 9*125 - 9*39 = 1,800

Answer:

4/5 or 0.8

Step-by-step explanation:

so, -4/4 and 1/5 are both already fractions.

160% as a decimal would be 1.6. 1.6 as a fraction would be 8/5.

-4/4 is just -1

-1+1/5+8/5

so, -5/5 +1/5 +8/5

-5/5 plus 9/5

4/5
