Merry Christmas. Have fun.

The size of ∠CDE labelled d° = 95° Given,

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Given,

In triangle DAF

∠DAF = 25°

∠DFA = 40°

Sum of all interior angles is 180°

∠DAF + ∠DFA + ∠ADF = 180°

25° + 40° + ∠ADF = 180°

65° + ∠ADF = 180°

∠ADF = 180° - 65°

∠ADF = 115°

Triangle DFE is equilateral

∠FDE = 60°

ABCD is an square

∠CDA = 90°

Now,

∠CDA + ∠ADF + ∠FDE + ∠CDE = 360°

90° + 115° + 60° + d° = 360°

d° = 360° - 265°

d° = 95°

Hence, 95° is the size of ∠CDE labelled d°.

Answer:

3,052 cubic inches

Step-by-step explanation:

·· A beach ball has a spherical shape

·· Formula to calculate the volume of a sphere is given as:  

In the question, we are given

Diameter = 18 inches

We have to find the radius

Radius = Diameter/2

Radius = 18 inches/2

Radius = 9 inches

The volume of the beach ball =  

= 3,052.08 cubic inches

Approximately to the nearest whole number = 3,052 cubic inches

Step-by-step explanation:

Volume of a cylinder=

[tex]\pi \: {r}^{2} h[/tex]

Radius=84÷2=42

Volume=22/7×42²×150=831 600 cm³

Answer:

No

Step-by-step explanation:

If (x + h) is a factor of f(x) then f(- h) = 0

Here (x + 2) with h = - 2 , then

f(- 2) = (- 2)³ - 7(- 2)² + 2(- 2) - 8

       = - 8 - 7(4) - 4 - 8

      = - 8 - 28 - 12

     = - 48

Since f(- 2) ≠ 0 then (x + 2) is not a factor of f(x)

The common denominator of the given expression is [tex]5y+6.[/tex]

Given expression,

[tex]\dfrac{y+\frac{y-3}{3} }{\frac{5}{9} +\frac{2}{3y} }[/tex].

We have to find the common denominator.

On solving the numerator and denominator of the  given expression,

[tex]\dfrac{y+\frac{y-3}{3} }{\frac{5}{9} +\frac{2}{3y} }= \dfrac{\frac{3y+y-3}{3} }{\frac{5y+6}{9y} }[/tex]

       [tex]= \dfrac{\frac{4y-3}{3} }{\frac{5y+6}{9y} }[/tex]

[tex]= \dfrac{4y-3}{3} \times\dfrac{9y}{5y+6}[/tex]

Or,[tex]\dfrac{y+\frac{y-3}{3} }{\frac{5}{9} +\frac{2}{3y} }= \dfrac{3y(4y-3)}{5y+6}[/tex]

Hence the common denominator of the above expression is given by [tex]5y+6.[/tex]

0.50x175 = 87.5 + 80 = 167.5

Answer:

To get 6 1/3 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction. Here are the detailed math steps we use to convert 6 1/3 mixed number to decimal form: Step 1:Multiply the whole number by the denominator: 6 × 3 = 18

Step-by-step explanation:

The value of the expression 6 - 1/3 will be 17 / 3.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The numbers are given below.

6 and 1/3

Then the difference between the numbers 6 and 1/3 will be given by putting a minus sign between them. Then we have

⇒ 6 - 1/3

⇒ (18 - 1) / 3

⇒ 17 / 3

The value of the expression 6 - 1/3 will be 17 / 3.

Step-by-step explanation:

What is 7/4 plus 2/3?

FractionCalculator

It can sometimes be difficult to add fractions, such as 7/4 plus 2/3.

But it's no problem! We have displayed the answer below:

7/4 + 2/3 = 2 5/12

How did we solve the problem above? When we add two fractions, such as 7/4 + 2/3, we make sure that the two denominators are the same and then we simply add the numerators.

In cases where the denominators are not the same, we find the lowest common denominator and adjust the fractions to keep them.

Rosie counts 324 + 236 shoes

Let's start by separating each number into hundreds, tens, and ones

300, 20, 4

200, 30, 6

Then, we can add up each section

300 + 200 = 500

20 + 30 = 50

4 + 6 = 10

Finally, we can add up the sections

500 + 50 + 10 = 560
