Answer:

4.8cm

Step-by-step explanation:

a²+b²=c² where c is the hypotenuse so

Let's plug in those values

11²+b²=12²

b²=12²-11²

b²=23

b=4.8

Calculate the standard deviation for each data set:

Sample A = 1.246

Sample B = 2.924

The smaller the deviation the closer the data set is, the larger the deviation the more widespread the data set is.

Sample B has a larger deviation so the spread of the data is wider.

Answer/Step-by-step explanation:

✔️Diagonals of a rhombus bisect each other at 90°.

Therefore,

m<1 = 90°

✔️Since opposite sides of a parallelogram are parallel, therefore:

m<2 = 53° (alternate angles)

✔️Diagonals bisect each angle of a parallelogram, therefore,

m<3 = m<2

m<3 = 53°

✔️m<4 + m<3 + 90° = 180°(sum of triangle)

m<4 + 53° + 90° = 180° (substitute)

m<4 = 180 - 143

m<4 = 37°

Step-by-step explanation:

In order to find the slope, we must know the formula needed.

[tex]\frac{y2}{x2} -\frac{y1}{x1} =m[/tex]

Using 2 given points, we can subtract both and receive our final answer.

Points that are provided:

Substitute the given points into the formula format.

Then, solve.

[tex]\frac{3}{4} -\frac{-1}{1} =\frac{4}{3}[/tex]

m = 4/3

The slope is positive. Meaning that the slope is increasing for the value of y.

Answer:

[tex] \frac{14}{4} [/tex]

simplified [tex] \frac{7}{2} [/tex]

Step-by-step explanation:

To turn a mixed number into a fraction :

[tex]3\frac{ + 2}{ \times 4} [/tex]

3 x 4 =12 +2 =14 that will be your numerator (top number on a fraction)

and 4 will be your demoninator (bottom number)

Answer:

B.

Step-by-step explanation:

-2/3

from the y-intersect (0,0), you went up 2 units(positive) and left 3 times (negative) to get the other points so negative and positive are negative.

Answer:

40%

Step-by-step explanation:

The first step is to add 18 girls + 12 boys, which gives you the total number of people on the swim team, 30.

Next, you divide the 12 boys by the total swim team members, so:

[tex]\frac{12}{30}[/tex] = 0.4

Then, you multiply 0.4 by 100 to get the percentage:

0.4 × 100 = 40

Therefore, the swim team is made up of 40% boys, and 60% girls.

Answer:

40%

Step-by-step explanation:

30 total kids

12/30 as a decimal is 0.4

to make a decimal into a percent you move the decimal point 2 times to the right

that would be 40

then add the percent to make 40%

Answer:

$92.50

Step-by-step explanation:

$72 - $35 = 37

37 / 0.40 = 92.5

Answer = $92.50

Answer:

557.8

Step-by-step explanation:

Because the semi circle on the top and the semi circle on the bottom form a circle with an area of 314.16.

The semicirlces on either side form a circle with an area of 66.48.

Then the rectangle in the middle has an area of 9 times 20 which is 180.

If you add those areas together you get the total area which is about 557.8

I hope this is helpful :)

Answer:

Number of 8th Graders = 360 - X  

As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from 8th grade.

As we know:

Total number of students on the A honor roll = 360

We are asked to calculate, number of students from 8th grade on the A honor  roll.

So, let's assume that "X" represents all the students who are on the A honor roll except 8th grade.

Mathematical Expression:

Number of 8th Graders = Total number of students on the A honor roll - X

Number of 8th Graders = 360 - X

So, if you know the value of X, you can easily calculate the number of students which are from 8th grade on the A honor roll.

I am not sure if it is wrong I am sorrry.

Answer:

25

Step-by-step explanation:

2x=x+25

2x-x=25

x=25

Answer:

Step-by-step explanation:

according to the question

[tex] \sf \: 2x + 4 + 62 = 90[/tex]

simplify addition:

[tex] \implies \sf 2x + 66 = 90[/tex]

subtract 66 from both sides:

[tex] \sf\implies 2x + 66 - 66 = 90 - 66 \\ \sf\implies2x = 24[/tex]

divide both sides by 2:

[tex] \sf \implies \: \frac{2x}{2} = \frac{24}{2} \\ \sf \therefore \: x = 12[/tex]

Answer:

Solution given:

62°+2x+4+90=180°[ sum of interior angle of a triangle is 180°]

2x=180-156°

x=24°/2

x=12°

Answer:

1 3/4 cups of wheat flour is in the bowl

Step-by-step explanation:

x + 2/3 = 2 5/12

First, convert the 2/3 to 12ths by multiplying numerator and denominator by 4 = 8/12

Then convert the 2 5/12 to an improper fraction 29/12

x + 8/12 = 29/12

subtract 8/12 from both sides

x = 21/12 = 1 9/12 = 1 3/4

Answer:

5,5,9 triangle is possible

3,4,5 triangle is also possible

all other length combinations aren't possible to form triangles.

Answer:

200 minutes

Step-by-step explanation:

Let us assume the number of minutes be x

Now the two equations are

$8 + 0.12x = 0

And, $18 + 0.7x = 0

In the case when the cost of the two plans is equal

So

$8 + 0.12x  = $18 + 0.7x

$8 - $18 = 0.7x - 0.12x

-$10 = -0.05x

x = 200 minutes
