A glass of cold milk is sitting on the counter, warming up to room temperature. Currently, the milk is 10°C below room temperature. However, that temperature difference is shrinking by 10% every minute. What will the temperature difference be in 14 minutes?

Answer:

draw a line that makes a triangle and rectangle.

hypotenuse= 30

3k-4k-5k triangle

18-24-30

so the short part of triangle is 18 cm

10+10+18+24+30 equals 92

sorry for language I am not familiar with English

the perimeter of this shape is

24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm

Answer:

38°

Step-by-step explanation:

L = 180 - 134 = 46°

M = 180 - 84 = 96°

O?

━━━━━━━━━━━━

O = 180 - L - M

O = 180 - 46 - 96

O = 38°

So the value of x is 38°

Answer:

c) 78 plants

Step-by-step explanation:

The total required is,

→ x = 143/11

→ [ x = 13 ]

Then number grew into plants,

→ 6 × x

→ 6 × 13

→ 78 plants

Hence, the option (c) is correct.

Answer: 78

Step-by-step explanation: 143 /11=13x6=78

Answer:

This represents a proportional relationship, the ratios are equivalent, and the constant of proportionality is 7.7.

Step-by-step explanation:

Since we know that six cell phones weigh 46.2 oz, we can divide 46.2 by 6 to find the weight of each, so 46.2/6=7.7.

We also know that fourteen cell phones weigh 107.8 oz, so we divide 107.8 by fourteen and get 7.7 as well.

Since both ratios equal 7.7 oz per cell phone, the ratios are equal and the relationship is proportional.

Greater than 1/2: 6/8, 3/4, 5/8, 7/8

Equal to 1/2: 2/4

Less than 1/2: 1/4, 2/8

Answer:

60

Step-by-step explanation:

First you have to get how long it took to get there, you can do that by adding 6 and 24 (walking distance and bus ride distance) That will get you 30 now we need to times that by 2 to get how long it took to get there and to get back. That will make the answer 60!

Answer: $4000

Step-by-step explanation:

In the age of cars you go 9.5 and then go up till you reach a part of the line.  In that, you can see that 9.5 goes up and reaches the line at $4000.

The predicted price you would pay if you purchase one of these cars that is 9.5 years old is 4000.

A scatter plot is a graphical representation of bivariate data that uses dots to represent values for two different variables.

The data for each observation is represented by the position of the dot on the x-axis and y-axis.

The x-axis represents one variable and the y-axis represents the other variable.

Scatter plots are commonly used to observe relationships between variables, such as correlations or trends, and to identify outliers or patterns in the data.

We have,

To predict the price you would pay for a car that is 9.5 years old, you need to look at the scatter plot and find the point that corresponds to an age of 9.5 years.

Once you have identified that point, draw a vertical line from that point to the line of best fit (or draw the line of best fit if it's not already on the plot).

Next, draw a horizontal line from the point where the vertical line intersects the line of best fit to the y-axis.

This will give you an estimated price for a car that is 9.5 years old based on the data in the scatter plot.

Now,

We see that,

At 9.5 years, the vertical line and the horizontal line correspond to a resale value of 4000.

Thus,

The predicted price you would pay if you purchase one of these cars that is 9.5 years old is 4000.

Step-by-step explanation:

there are 5 data points

3*40 =120

5*52.5 = 262.5

It's 1/2  I found this out by subtracting 3/4 - 1/3= 5/12 and if you put that into a decimal it would be .41. So that 1/4= .25 and 1/2= .50. You could figure out that it’s closed to 1/2.

Step-by-step explanation:

10)We have to calculate the average speed if we know the distance and time that Johnatan can jog. The distance

distance=3 2/5 miles = 3.4 miles.

Time=7/8 hour = 0.875 h

Then we will use the formula for the average speed ( velocity )

velocity=distance/time. v = 3.4 m / 0.875 h = 3.866 mph

so therefore The average speed is 3.866 mph.

11) divide 120 / 7/4 (remember 120 = 120/1)

Which means you have to cross multiply (an important part on fraction division, that is, your division would be 120x4 / 1x7).

Then 120x4= 480

And 1x7 = 7

Then you get 480/7, which is the same as 68 4/7 mph

Step-by-step explanation:

Answer: the perimeter of the garden is 38 units.

Step-by-step explanation:To find the perimeter of the garden, we need to add up the lengths of all four sides.

Starting with the bottom side, we can use the coordinates (-7, 2) and (4, 2). The distance formula tells us that the distance between these two points is:

d = √[(4 - (-7))^2 + (2 - 2)^2]

 = √[11^2 + 0^2]

 = √121

 = 11

So the bottom side has a length of 11.

Moving to the right side, we can use the coordinates (4, 2) and (4, 10). Again using the distance formula, we get:

d = √[(4 - 4)^2 + (10 - 2)^2]

 = √8^2

 = 8

So the right side has a length of 8.

For the top side, we can use the coordinates (4, 10) and (-7, 10):

d = √[(-7 - 4)^2 + (10 - 10)^2]

 = √11^2

 = 11

So the top side also has a length of 11.

Finally, for the left side, we can use the coordinates (-7, 10) and (-7, 2):

d = √[(-7 - (-7))^2 + (2 - 10)^2]

 = √8^2

 = 8

So the left side has a length of 8.

Adding all four side lengths together, we get:

Perimeter = 11 + 8 + 11 + 8

         = 38

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143
