Mary buys a 10-meter spool of thread for sewing. She uses 210 centimeters. How much is left on the spool in centimeters? (4 points)
21 centimeters
190 centimeters
790 centimeters
2,100 centimeters

Answer:

a. (5x+75)°

b. x = 21

c. X° = 21° and (4x+75)°= 159°

Step-by-step explanation:

A. Combine like integers.

B. (5x+75)°=180° Because they are suplementary angles.

   5x°= 105°

   5x ÷5 = 105 ÷ 5

   x = 21

C. (4x + 75)°

   4(21) + 75

   84 + 75 = 159°

Answer: 20.48

Step-by-step explanation:

use the pythagorean theorem for the diagnal sides

3^2+3^2=c^2

9+9=c^2

18=c^2

[tex]\sqrt{18}[/tex]

this gives you 4.24

now add 6+6+4.24+4.24 to get 20.48

Answer:

A

Step-by-step explanation:

I didn't learn jrf, but I believe that it is the amount of females that watch action movies divided by the total amount of females.

Amount of females who watch action movies= 99

Total females= 250

So, A seems correct.

The joint relative frequency of being male and attending a drama film, divide 124 by 229.

The number of times an event occurs divided by the total number of events occurring in a particular scenario is described as relative frequency.

Two things must be understood in order to compute the relative frequency:

               Action           Drama              Total

Male           105                124                 229

Female       99                 151                  250

Total           204               275                 479

The joint relative frequency is the frequency in a given category divided by the total number of data values.

Here, The total number of males = 229

and, the number of males that like drama = 124

To calculate the joint relative frequency of being male and attending a drama film, divide 124 by 229.

With one dice the chance of rolling a one is 1/6.

With two you have twice the probability, so its 1/3.

This is because there are 6 sides on a dice.

Please mark brainliest if this helped!

Answer:

The probability of rolling at least one 1 is 1/3

Step-by-step explanation:

When there is one dice the probability of rolling a '1' is 1/6

When you roll two dice, the probability of rolling a '1' increases, making it a 1/3 of rolling a one.

Answer:

92.5 square inches

Step-by-step explanation:

Area of square:

10 * 10 = 100 square inches

Area of right triangle:

(1/2) * 5 * 3 = 7.5 square inches

Area of figure:

100 - 7.5 = 92.5 square inches

[tex]\bold{\huge{\underline{ Solution }}}[/tex]

Here, We have

We know that,

Area of rectangle

[tex]\bold{\red{ = Length {\times} Breath }}[/tex]

Subsitute the required values,

Area of large rectangle

[tex]\sf{ = 12 {\times} 8 }[/tex]

[tex]\sf{ = 96 \:units^{2}}[/tex]

Thus, The area of large rectangle is 96 units² .

Area of non - shaded rectangle

[tex]\sf{ = 9 {\times} 4 }[/tex]

[tex]\sf{ = 36\: units^{2}}[/tex]

Thus, The area of non shaded rectangle is 36 units² .

Area of shaded region

= Area of large rectangle - Area of non shaded rectangle

Subsitute the required values,

[tex]\sf{ = 96 - 36}[/tex]

[tex]\sf{ = 60\: units^{2}}[/tex]

Hence, The total area of shaded region is 60 sq.units.

➾Length(L) of bigger rectangle = [tex]\sf{9+3\: =\:12}[/tex]units.

➾Length(l) of smaller rectangle = 9units.

➾Breadth (B) of bigger rectangle = [tex]\sf{4+4 \:=\: 8}[/tex]units.

➾Breadth(b) of smaller rectangle = 4 units.

➾Area of the shaded region.

➾We can find the area of shaded region by subtracting area of smaller rectangle from area of bigger rectangle(that is whole rectangle including shaded and non shaded region).

So,

➾Area of bigger rectangle = [tex]\sf{L×B}[/tex](putting the value of L and B from the above given)

= [tex]\sf{8×12}[/tex]

= [tex]\sf{96unit^2}[/tex]

Similarly,

➾Area of smaller rectangle = [tex]\sf{l×b}[/tex](putting the value of l and b from the above given)

= [tex]\sf{9×4}[/tex]

= [tex]\sf{36unit^2}[/tex]

Now,

➾Area of shaded region = Area of bigger rectangle - Area of smaller rectangle.

[tex]\sf{= 96-36}[/tex]

[tex]\sf{= 60unit^2.}[/tex]

Therefore, area of shaded region[tex]\sf{= 60unit^2.}[/tex]

Answer:

Step-by-step explanation:

It does not have a common difference between each consecutive term, therefore it is not an arithmetic sequence.

Step-by-step explanation:

The value of x and y based on the percentages that are given will be 11 and 7.

How to calculate the percentage

Since x is 110% of 10. This will be;

= 110% × 10

x = 11

Since y% of 50 is 3.5. This will be:

y% × 50 = 3.5

y% = 3.5/50

0.01y = 3.5/50

y = 7

Therefore, it can be seen that value of x and y based on the percentages that are given will be 11 and 7.

Answer:

Step-by-step explanation:

20 hm = 2000 m

3,412 mm = 0.003412 km

0.25 m = 250 mm

590 mg = 0.59 g

75cm = 0.75 m

12.5 m = 0.0125 km

8,808 cm = 0.08808 km

20 hm = 2000000 mm

1,235g = 1.235 kg

12 decimeters = 0.12 dam

20 L = 20000 mL

13.6 mL = 0.0136 L

Hope this helps :)

Answer:

See below.

Step-by-step explanation:

Let's review the metric prefixes used in this problem:

m = 1/1000

h = 100

c = 1/100

k = 1000

da (deca) = 10

20 hm = 20 × 100 m = 2,000 m

3,412 mm = 3412/1000 m × 1 km/(1000 m) = 0.003412 km

0.25 m = 0.25 m × 1000 mm/m = 250 mm

590 mg = 590 mg × 1 g / (1000 mg) = 0.59 g

75 cm = 75 × m/100 = 0.75 m

12.5 m = 12.5 m × 1 km / 1000 m = 0.0125 km

8,808 cm = 8,808 cm × 1 m / 100 cm × 1 km / 1000 m = 0.08808 km

20 hm = 20 × 100 m × 1000 mm/m = 2,000,000 mm

1,235 g = 1,235 g × kg/(1000 g) = 1.235 kg

12 dm = 12 dm × 1 m / 10 dm × 1 dam / 10 m = 0.12 dam

20 L = 20 L × 1000 mL/L = 20,000 mL

13.6 mL = 13.6 mL × 1 L /  1000 mL = 0.0136 L

Answer:

Part A: impossible

Part B: Either equal or blue

Part C: 9 green and 2 blue were added

Step-by-step explanation:

Part A:

The only colors included in this problem are red, blue, and green. There is no black colored pencil, therefore, it is impossible to get one from the box.

Part B:

I'm not sure what you're asking in this question, but I will give you the two choices. If it is before the additional 11 colored pencils are added to the box, the chance of drawing a red and the chance of drawing a blue will be equal, because both of them have 11 of each color. If it is after the additional 11 colored pencils are added to the box, then the chance of drawing a blue colored pencil will be greater than the chance of drawing a red colored pencil. After the 11 colored pencils are added, there are 13 blue and 11 red. The blue is greater.

Part C:

The least number of green colored pencils added has to be 9, because the chance of drawing a green pencil is now greater than the chance of drawing a red pencil. If we add 8 more green pencils, the likelihood would be the same. Therefore, the number of green colored pencils added has to be at least 9. If we have the last 2 colored pencils be blue, then there would be 11 red, 13 blue, and 12 green. This fits all the conditions, therefore, adding 9 green colored pencils and 2 blue colored pencils is the answer.

Answer:

The circumference appears four times larger.

Step-by-step explanation:

C=2πr

So if we are multiplying the radius (r) by 4 then that would most definitely increase the outcome (circumference) by 4

here's why:

C=2πr

C=2π(4r)

C=8πr

So,

8πr/2πr = 8/2 = 4

1 one drag 1 one

Step-by-step explanation:

The answers to the questions are given below.

        where [a] is side length of cube.

        where [h] is prism height, [w] is its width, and [L] is its length.

We have the question as shown in the figure.

Cube with side length (1/5) :

Volume = (1/5 x 1/5 x 1/5) = 1/125 cm³

Prism of dimensions (L = 1/5, B = 2/5, H = 3/5) :

Volume = (1/5 x 2/5 x 3/5) = 6/125 cm³

Cube with side length (2/5) :

Volume = (2/5 x 2/5 x 2/5) = 8/125 cm³

Prism of dimensions (L = 3/5, B = 4/5, H = 3/5) :

Volume = (3/5 x 4/5 x 3/5) = 36/125 cm³

Therefore, the answers to the questions are given above.

Answer:

7

Step-by-step explanation:

72 divided by 6 = 12

84 divided by 12 = 7

Answer: It would be A

Step-by-step explanation:

First: Find Median

18,19,|19|,20,|20,20|,21,|22|,22,26

there is 10 numbers so it would be between 20 and 20. Add 20 and 20 and you will get 40 and divide by 2 to get 20. Your median is 20 and the dot should be on top of the 20.
Second: Find Quartile 1 and 3

Since it’s 5 numbers on each side, the math is friendly. So you count the first 2, then circle the next number and count the last 2. The one you circled is your Quartile 1 and do the same for Quartile 3. Q1 should be 19 and Q3 should be 22. Check if they are underneath that number you got.

Last: now you know that you just have to find the median and the Q1 and Q3 and you should get the answer which is A.
