how do I find the area

Answers

split the figure into a rectangle and trapezoid, the rectangles area is 9 * 6 or 54 and the area of the trapezoid is (11 + 6) divided by 2 so 8.5 * 9 or 76.5

76.5 + 54 = 130.5

Answer:

105cm2

Step-by-step explanation:

area= area f rectangle + area of trapezium

= (6x9)+( [tex]\frac{6+11}{2}[/tex]x6)

= 54+51

= 105 cm2

How would I solve the equivalent fraction to 2/6.?

Answers

Answer: See explanation

Step-by-step explanation:

To solve the equivalent fraction to 2/6, you divide or multiply the numerator and the denominator by thesame set for numbers. For example

2/6 = (2 × 3) / (6 × 3) = 6/18

2/6 = (2 ÷ 2) / (6 ÷ 2) = 1/3

The above fractions are both equivalent fractions of 2/6

3. Antony and Cleopatra are 100 miles apart . To meet at a planned location , Antony travels at 12 mph and Cleopatra travels at 8 mph. How far must Antony travel if they leave at the same time?

Answers

Answer:

60 miles

Step-by-step explanation:

Distance apart = 100

Rate of travel. :

Anthony = 12 mph

Cleopafda = 8 mph

Using the relation :

Speed = distance / time

Distance = speed * time

If they leave at the same time, travel time Can be represented as x

Anthony's distance + Cleopafda distance = total distance

12x +. 8x = 100

20x = 100

x = 5

Hence, they both traveled for 5 hours before meeting.

Distance covered by Anthony :

Speed * time

12 mph * 5h = 60 miles

Anthony must travel. For 60 miles.

If the principle is $4,000 and the rate of interest is 8% (simple interest), what is the amount of interest after one year?

Answers

Answer: $320

Step-by-step explanation:

A principal of $4,000 was invested.

The principal increases at a rate of 8% every year by simple interest.

After 1 year the total in the account can be calculated by the formula:

= Principal * ( 1 + rate * time)

= 4,000 * ( 1 + 8% * 1)

= $4,320

Interest:

= Amount after a year - original price

= 4,320 - 4,000

= $320

Determine whether the representation is proportional. y = -9x

Answers

Answer:

Yes, they are

Step-by-step explanation:

y = -9x

Here y∝ x

Where -9 is constant of proportionality

If "y" increases by factor of 2, then "x" will also increases by factor of 2. Hence, y and x are " directly proportional" to each other.

Can you guys solve this for me please

Answers

Answer:

50°

Step-by-step explanation:

all triangles = 180°

add 53 + 77 = 130

subtract 180 - 130 = 50

giving you your answer of 50°

Answer:

Step-by-step explanation:

The total angle of a triangle is 180

so add 77 and 53 to find out what you have so far

77 + 53 = 130

then you need to find the difference which you do by subtracting

180 - 130 = 50

so x = 50

Robin baked 702 cookies.He sold them in boxes of 18. After selling all of the boxes of cookies for the same amount each, he earned $136.50.what was the cost of one box of cookies

Answers

Answer:

cost of a box is $3.5

Step-by-step explanation:

given data

sold box = 18

earned = $136.50

solution

we consider here number of boxes of cookies is x

and

for we get Tyler sold cookies box so number of boxes we divide 702 cookies among 18 is

Tyler sold = [tex]\frac{702}{18}[/tex]

Tyler sold = 39 boxes

and

now we consider here y as cost of each box of cookies,

so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes

cost of each box = [tex]\frac{136.5}{39}[/tex]

cost of each box = 3.5

Thus, the cost of each box was 3.5
