I need help on this will give brainlist

Answer:

Let the parts be given as x,

180° = 3x + 1x + 4x (Because a straight angle = 180°)

=> 180° = 8x

=> 180 / 8 = x (By the law of transposition)

=> 22.5 = x

Therefore the three different angles are :

67.5° , 22.5° , 90° respectively

Check,

=> 67.5 + 22.5 + 90

=> 90 + 90

=> 180°

If my answer helped, please mark me as the brainliest!!

Thank You!

Answer:

length-x

width-x-4

area-- length* width

192=X*(X-4)

x^2-4x-192=0

x^2-16x+12x-192=0

X(x-16)+12(x-16)=0

(x-16),(X+12)

X= 16 because X cannot be negative like (-12)

the dimensions of the classroom will be

length = 16

width = 12

I hope this will help everyone

Answer:

ZDM is not a name for the angle, 6 square units is the area, A the cylindar, 26 degrees

Step-by-step explanation:

Area of triangle is 1/2 base x height

116-90 = 26 degrees to angle ABC

Step-by-step explanation:

8(x + 9)

8x + 72 = 0

8x = -72

x = -72/8

x = -9

Answer:

Given : 8(x + 9)

Solution :

[tex]8(x + 9) = 0\\ [/tex]

Multiply 8 to both x and 9

[tex]8x + 72 = 0 \\ [/tex]

Now, Move 72 to RHS from LHS

[tex]8x = - 72 \\ [/tex]

[tex]x = \dfrac{ - 72}{8} \\ [/tex]

And the final ans we get is :

[tex]\boxed{x = - 9}[/tex]

Answer:

0.05

Step-by-step explanation:

we are given the formula

I = Prt, where

I = interest earned = $450

P = Principal amount = $3000

t = time = 3 years

r = rate (we are asked to find this_

Simply substitute the known values into the equation

I = Prt

450 = 3000 x r x 3

450 = 9000r

r = 450/9000

r = 0.05

Answer:

Answer:

x = -11

Step-by-step explanation:

5 + (x - 2) = -8

Subtract 5 from both sides.

x - 2 = -13

Add 2 to both sides.

x = -11

Step-by-step explanation:

i only see the explanation

Step-by-step explanation:

The area of a rectangle is 171 m²

Let l is the length and b is the width of the rectangle

It width is 10 m less than the length. So,

b = l-10 ...(1)

Area of a rectangle is given by :

[tex]A=l\times b\\\\171=l(l-10)\\\\l^2-10l=171\\\\l^2-10l-171=0\\\\l^2-19l+9l-171=0\\\\\text{taking common together}\\\\l(l-19)+9(l-19)=0\\\\(l-9)(l-19)=0[/tex]

or

l = 9 m or l = 19 m

If l = 9 m,

b = 9-10 = -1 m (can't be possible)

If l = 19 m

b = 19-10 = 9 m

So, the length an the breadth of the rectangle is 19 m and 9 m respectively.

Answer:

A. 0.22

B. 0.18

C. 0.25

D. 0.244

Step-by-step explanation:

S = {51 to 100} = 50

The sample space S contains values from 51 to 100 which is a total of 50 different values.

A.

Probability of A (lies between the values of 90 to 100 = 11).

11/50 = 0.22

B.

For a student to fail the course, his course has to be less than 60 = from 51 to 59. A total of 9 values.

9/50 = 0.18

C.

For student to get c, (70 to 79) a total of 10 values: 10/50 = 0.20

P(student did not get C) = 1-0.20 = 0.80

To get B, ( 80 to 89)

10/50 = 0.20

Probability that a student who is known not to have a c grade has a b grade = 0.20/0.80 = 0.25

D.

Probability of passing lies between 60 to 100 = 41 scores

41/50 = 0.82

Probability of student who passed having a B = 0.20/0.82 = 0.244

Answer:

30 adult tickets and 50 child tickets

Step-by-step explanation:

605 = 8.5a + 7c

80 = a + c

620 = (8.5*40) + (7*40)

605 = (8.5*30) + (7*50)

a = 30  c = 50

The partial products of 73 x 8 is = 584

The partial products algorithm allows students to multiply two long numbers fast and easily by breaking down a more challenging product into a series of simpler problems.

(70 +3 ) * (8)

= 70 x 8  = 560 and ;

= 3 x 8 =  24

Step 2 - Add all the products together

560 + 24 = 584

Answer:

  3 significant digits

Step-by-step explanation:

If there is a decimal point with non-zero digits to its left, all digits to the right of the left-most non-zero digit are significant. Here, that is all of them. This number has 3 significant digits.

__

Comment on other cases

If there is no decimal point, the digits between any leading and trailing zeros are significant. For example, 02000 has 1 significant digit.

If there are no non-zero digits left of the decimal point. All digits except leading zeros are significant. 0.0031000 has 5 significant digits.
