Answer:

61.25

Step-by-step explanation:

7x 3.5 x 1/2= triangle

12.25 x 4 =49

3.5 x 3.5 = 12.25

12.25+49 = 61.25

Answer:

[tex] \frac{n}{3} - 7[/tex]

Step-by-step explanation:

The comma is important here, otherwise "one third of a number n minus 7" is

[tex] \frac{n - 7}{3} [/tex]

The algebraic expression represents “one-third of a number, n, minus 7

” could be; 1/3n - 7.

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like , subtraction, addition, multiplication, and division.

The Numbers constants, variables, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols.

We are given that “one-third of a number, n, minus 7”

Therefore, the number n and 7 then it can be written as

1/3n - 7

The algebraic expression represents the statement is 1/3n - 7.

1. false

2. true

3. true

4. false

the first one is false- the second one is false the third one is false and the last one is true

Answer:

9

Step-by-step explanation:

Both sides are going to be exactly the same angle. So if its 35° on the right it will be 35° on the left also.

Let me know if you have any questions!

Answer:

In the given figure AD is internal bisector of angle A and CE is parallel to DA. If CE meets BA produced at E.

to prove :AC=AE

<BAC + <EAC = 180° ( Straight line)

In triangle ACE

<ACE + <AEC + <EAC = 180° (sum ofangles of Triangle)

Equating both

<BAC + <EAC = <ACE + <AEC + <EAC

=<BAC = <ACE + <AEC.......... Eq 1

<BAD = (1/2) <BAC

<BAD = <AEC so (AD || CE)

we get

<AEC = (1/2) <BAC

putting this in eq 1

=<BAC = <ACE + <AEC Eq1

<BAD = (1/2) <BAC

<BAD = <AEC (AD || CE)

=<AEC = (1/2) <BAC

<AEC=<ACE=1/2 <BAC

: AC = AE

hence proved.

Answer: $357

Step-by-step explanation: Please see images below!

The amount she have to spend to paint the wall is $357.

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

The side of two hexagon is 2ft, painting measures 9*25ft.

Now,

In this case, s = 2 feet. Therefore, the area of one hexagonal window is:

Area = (3√3 × 2²)/2 Area = (12√3)/2 Area ≈ 10.39 square feet

Since there are two windows, we need to multiply this by 2 and subtract it from the total area of the wall:

225 - (2 × 10.39) ≈ 204.22 square feet

This is the area that needs to be painted. To find how much Deb will have to spend, we multiply this by $1.75 per square foot:

204.22 × $1.75 ≈ $357.39

Rounding this to the nearest dollar, we get:

$357

Therefore, by the area of painting the answer will be $357.

Answer:

The 1st answer.

Step-by-step explanation:

1. Find the quotient to 1/3 ÷ 3/4

Your quotient should be 4/9

2. Solve all of the expressions

1st answer choice product: 4/9

2nd answer choice product: 4

3rd answer choice product: 2 1/4

4th answer choice product: 1/4

3. The only answer that was equivalent to  1/3 ÷ 3/4 was answer choice 1 therefore the first answer choice was the correct answer choice.

The original price was £52 if the t-shirt increased in price by 1/4. After the increase, it was priced at £65.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The question is incomplete.

Please refer to the picture for the complete question.

We have:

A t-shirt increased in price by 1/4. After the increase, it was priced at £65.

Let's suppose the original price was x

(1 + 1/4)x = 65

(1 + 0.25)x = 65

1.25x = 65

x = £52

Thus, the original price was £52 if the t-shirt increased in price by 1/4. After the increase, it was priced at £65.
