Step-by-step explanation:

The difference between the sector and the segment of a circle is :

Sector ➡ The region enclosed by any two radii and the corresponding arc of a circle is a sector of the circle.

Whereas

Segment ➡ The region enclosed by a chord and corresponding arc is called the segment of a circle.

Hope it will help :)❤

Step-by-step explanation:

Perimeter = 2(l+b)

2(x+x-10)=100cm

(x+x-10)= 100 divided by 2

(x+x-10)=50

2x-10=50

2x=50+10,60

x=60 divided by 2

X =30

Length = 30cm

Breadth= 30-10= 20cm

PLEASE MARK MY ANSWER AS THE BRAINILIEST!

Answer:

solution given:

length[l]=xcm(let)

breadth [b]=(x-10)cm

perimeter of rectangle [P]=100cm

we have

P=2[l+b]

100cm=2[x+x-10]

2x-10=[tex] \frac{100}{2} [/tex]

2x=50+10

x=[tex] \frac{60}{2} [/tex]

:.x=30cm

So

length[l]=x=30cm

breadth [b]=(x-10)=30-10=20cm

Answer:

(1,3/2)

Step-by-step explanation: x=(-4+6)/2=1

Y=(8-5)/2=3/2

Answer:

2

Step-by-step explanation:

(-2 , 1) ; (1, 2.5)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

         [tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]

m =0.5

y -y1 =m(x -x1)

y - 1 = 0.5(x - [-2])

y - 1 = 0.5(x + 2)

y -1 = 0.5x + 0.5*2

y - 1 =0.5x + 1

  y = 0.5x + 1 + 1

 y = 0.5x + 2

y-intercept = 2

Answer:6 11/40

Step-by-step explanation: You can change your units to decimals or to fractions of equal value.  Decimals are easier for this so 8 7/8= 8.875 and 2 3/5 =2.6.  Then subtract: 8.875-2.6= 6.275   You can now convert back to a fraction by simplifying the .275 into 11 by dividing by 25 and 1000 into 40 by dividing by 25.  6+11/40= 6 11/40 tea left

Answer:

6 11/40

Step-by-step explanation:

First you have to convert the fractions into improper fractions, where 8 7/8 would turn into 71/8 and 2 3/5 would turn into 13/5. Then you have to find a common denominator which would be 40, so you get 355/40 and 104/40. Then to find the remaining amount, you have to subtract 104/40 from the 355/40, so 355/40 - 104/40, which equals 251/40. This turns into 6 11/40, which can't be simplified any further. Hope this helps :)

Step-by-step explanation:

The discriminant informs us about the nature of the zeros

• If b² - 4ac > 0 then 2 real and distinct zeros

• If b² - 4ac = 0 the 2 real and equal zeros

• If b² - 4ac < 0 then zeros are not real

The graph crosses the x- axis at 2 distinct zeros, then

b² - 4ac > 0 , that is positive → C

The amount of money Mary has left in her account is $ 45

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount of money in Mary's account be = $ 120

The amount of money that gets deducted for each week = $ 5

Total number of weeks elapsed = 15 weeks

So , the equation will be

Total amount deducted after 15 weeks = number of weeks elapsed x amount of money that gets deducted for each week

Total amount deducted after 15 weeks = 15 x 5

                                                                 = $ 75

Therefore , the equation will be

The amount left in Mary's account = total amount of money in Mary's account - Total amount deducted after 15 weeks

The amount left in Mary's account = 120 - 75

                                                         = $ 45

Hence , The amount of money Mary has left in her account is $ 45

The first three terms are [tex]3,6,11[/tex]

The 10th term is [tex]102[/tex]

Step-by-step explanation:

An ordered list of numbers is known as a sequence such that each number in the sequence is called a term.

The nth term is [tex]a_n=n^2+2[/tex].

To find the first 3 terms, put [tex]n=1,2,3[/tex]

[tex]a_1=1^2+2=1+2=3\\a_2=2^2+2=4+2=6\\a_3=3^2+2=9+2=11[/tex]

To find the 10th term, put [tex]n=10[/tex] in [tex]a_n=n^2+2[/tex]

[tex]a_{10} =(10)^2+2=100+2=102[/tex]

Answer:

228

Step-by-step explanation:

A cuboid consists of 6 sides, 2 sides will be 9*6, 2 more will be 6*4, 2 more will be 6*9

So because there is 2 sides you will multiply the side by 2 so there is another side:

(6*9) * 2 = 108

(4*6) * 2 = 48

(4*9) * 2 = 72

108 + 48 + 72 = 228

Hi there!

Answer:

x=0

How it works:

In coordinate planes, x always goes first. Then the y comes next. If x is 0, and y is also zero, none of those would be in the y axis place...

If the x is in 0 and the y is 1,2,3,4,5.... then the y axis would be in the y axis and x would just stay the same...

If the x is 1, then the y would be 0 which means that there would be nothing in the y axis.

Therefore, the answer is x=0..
