Answer:

1st Question:

m<1 = 90°

m<2= 79°

m<3= 101°

2nd Question:

m<1=97°

m<3=83°

m<6=83°

Step-by-step explanation:

1st Question :

m<1 is a right angle.

m<2 is 79° because of parallel line denote the same angle.

m<3 is 101° because 180°-79°=101°.( As we know sum of angles in a straight line = 18° degree. )

2nd question:

m<1 is 97° because sum of angles in a straight line = 180°

                    So, 180°-83°=97°

m<3 is 83° because sum of parallel sides are equal.

m<6 is 83° because sum of parallel sides are equal.

Answer:

10976

Step-by-step explanation:

First lets start off by finding out how many cats there are (not kittens).

There were 7 girls, with 7 bags each, which contained 7 cats.

That turns into 7^3 or 7 * 7 * 7

7^3 = 343 cats

343 cats * 4 legs = 1372 legs (keep this for later).

Now you must find out how many kittens there are.

343 cats with 7 kittens each = 343 * 7

2401 kittens * 4 legs = 9604 legs

Now you must bring in the legs of the cats and kittens and add them together.

1372 legs (cats) + 9604 legs (kittens) = 10976 legs (total)

Answer:

-2  Means Day 2  & 21 is commute time

Step-by-step explanation:

The coordinate plane below shows some of his commute times in the last two weeks.

See attached graph

Yesterday  means - 1

Days  8 means  - 8  

Day 9 means    -8

- 8 has dot  on  24   => Commute time on Days 8  = 24 minutes

-9 has dot  on   18   => Commute time on Days 9 = 18 minutes

2 days ago,   Paulo's commute time was halfway between his commute times 8 and 9 days ago.

=> Commute time on Days 2  =(24 + 18)/2 = 21

Day 2  =  - 2

Coordinate  = (-2 , 21 )        

-2  Means Day 2  & 21 is commute time

Answer:

Step-by-step explanation:

Profit % = \(\frac{New Value - Old Value}{Old value}\)x 100

Loss % = \(\frac{Old Value-NewValue}{Old Value}\)

Profit % = \(\frac{16.1-5}{5}\) × 100

= \(\frac{11.1}{5}\) x 100

= 11.1 x 20

= 222% increase

∴ Hence, proved that the answer is correct.

Profit % = \(\frac{57.6-40}{40}\)×100

= 44% increase

∴ Hence, proved that the answer is correct.

Profit % = \(\frac{63.6-60}{60}\)x 100

= 6% increase

∴ Hence, proved that the answer is correct.

Loss % = \(\frac{110-13.2}{110}\)x 100

= 88% decrease

∴ Hence, proved that the answer is correct.

Loss % = \(\frac{55-49.5}{55}\)x 100

= 10% decrease

∴ Hence, proved that the answer is correct.

Hope it helped. Pls mark me the BRAINLIEST! For all the writing and you understanding :)

Answer:

Step-by-step explanation:

Old Value:  5

            New Value:   16.1

16.1-5=11.1

11.1 divided by 5= 2.22

2.22/1 x 100=222%

222% increase

Old Value:  40

            New Value:  57.6

57.6-40=17.6

17.6 divided by 40= 0.44

0.44/1 x 100= 44%

44% increase

Old Value:  60

           New Value:   63.6

63.6-60=3.6

3.6 divided by 60= 0.06

0.06/1 x 100= 6%

6% increase

Old Value:  110

           New Value:   13.2

13.2-110= -96.8

-96.8 divided by 110= -0.88

-0.88/1 x 100= 88%

88% decrease

No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.

So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.

Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Step-by-step explanation:

The smallest 9 digit number of the form aaa, aaa, aaa such that it is divisible by 9 is, 111,111,111.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The number of the form aaa,aaa,aaa is divisible by 9.

Now, We can write the number as;

⇒ 111,111,111

Clearly, Above number is divisible by 9.

Hence, The smallest 9 digit number of the form aaa, aaa, aaa such that it is divisible by 9 is, 111,111,111.

Answer:

[ 2] − | −5 + 7 |

Step-by-step explanation:

Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.

Step 1) Solve. | −5 + 7 | = 2.

Step 2) Find which other absolute value is equal to -2.

After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.

We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y  = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y  = $551.97 (a)

===================  -

33x           = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Step-by-step explanation: you guys are wrong on all of this

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
