10.ABCD is a rhombus such that measure of angle ACB is 40º find the measure of angle ADC.​

Answers

Answer 1

Answer:

ADC = 100 degrees

Step-by-step explanation:

Please check attachment for diagrammatic representation of the Rhombus

From what we can see in the diagram;

angle CBD and CDB are equal

The reason for this is that we have an isosceles in triangle CBD

CBD = 90- ACB

CBD = 90-40 = 50

We need ADB to completely calculate ADC

CAB is also 40 from the isosceles ABC

That means DBA = 90 - CAB = 90-40 = 50

So from isosceles ABD, we have that ADB is also 50

Mathematically;

ADC = ADB + DBA

ADC = 50 + 50

ADC = 100

10.ABCD Is A Rhombus Such That Measure Of Angle ACB Is 40 Find The Measure Of Angle ADC.

I keep getting this question wrong

Answers

Answer: see below

Step-by-step explanation:

Set up two equations, one for each scenario

88w + 21b = 5840

84w + 82b = 9044

Use one equation and isolate one of the variables. We'll isolate w in the first equation.

88w + 21b = 5840

88w = 5840 - 21b

w = (5840 - 21b)/88

Then substitute that into the second equation.

84w + 82b = 9044

42w + 41b = 4522 (simplified)

42((5840 - 21b)/88) + 41b = 4522

21((5840 - 21b)/44) + 41b = 4522 (simplified)

(122640 - 441b)/44 + 1804b/44 = 4522

(122640 - 441b + 1804b)/44 = 4522

122640 + 1363b = 198968

1363b = 76328

b = 56

Now that we know belts are $56, we can substitute that back into any equation and solve for w.

w = (5840 - 21b)/88

w = (5840 - 21(56))/88

w = (5840 - 1176)/88

w = 4664/88

w = 53

A farmer has chickens and pigs on a farm. The farmer counted 22 heads and 56 feet on all the animals. How many chickens and pigs does the farmer have?

Answers

Answer: 16 chickens, 6 Pigs

Step-by-step explanation:

Given

Toal heads=22

Total feet=56

Suppose there are x chickens and y pigs

each animal possess a single head

[tex]\therefore\ x+y=22\quad \ldots(i)[/tex]

Chicken has 2 legs and pig has 4 legs

So, [tex]2x+4y=56\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

x=16 and y=6

So, farmer has 16 chickens and 6 pigs

A building casts a shadow 46 feet long. At the same time, a 36 foot tall flagpole costs a shadow of 9.2 feet long. what is the height of the building

Answers

Given :

A building casts a shadow 46 feet long.

At the same time, a 36 foot tall flagpole costs a shadow of 9.2 feet long.

To Find :

The height of the building.

Solution :

Since, all readings are taken in same time.

Ratio of height and shadow remains for all objects.

Let, height of building is H.

So,

[tex]\dfrac{H}{46}=\dfrac{36}{9.2}\\\\H = \dfrac{36}{9.2}\times 46\\\\H = 180\ feet[/tex]

Therefore, height of the building is 180 feet.

Find and simplify an expression for the area of three rows of m squares with side lengths of m centimeters. Please help

Answers

The expression for the area of three rows of m squares with side lengths of m centimeters is [tex]3m^3[/tex] square centimeters.

To find the area of three rows of m squares with side lengths of m centimeters, determine the total number of squares.

Each row consists of m squares, and there are three rows in total. Therefore, the total number of squares is 3m.

The area of each square is given by the formula

[tex]A = s^2[/tex],

where s is the length of the side.

Multiply the area of one square by the total number of squares:

Area = (Area of one square)  (Total number of squares)

Area = [tex]m^2[/tex] * 3m

Area = [tex]3m^3[/tex]

Therefore, the expression for the area is [tex]3m^3[/tex] square centimeters.

The simplified expression for the area of three rows of m squares with side lengths of m centimeters is 3 * m^3 square centimeters.

To find the area of three rows of m squares with side lengths of m centimeters, we need to determine the total area covered by the squares.

Each row consists of m squares, and each square has a side length of m centimeters. Therefore, the length of each row is m * m = m^2 centimeters.

Since there are three rows, the total length covered by the rows is 3 * m^2 centimeters.

To find the area, we need to multiply the total length by the width, which is also m centimeters. Thus, the area of the three rows of squares is:

Area = Length * Width

Area = (3 * m^2) * m

Area = 3 * m^3 square centimeters
