Answer: 77 percent

Step-by-step explanation:

The value of the stock decrease by 23.13%.

The difference between starting and final numbers is the percentage drop. It displays a percentage loss of value compared to the original regardless of the units. The difference between the initial and final amounts is the amount of decline.

Given:

The price of the stock was $35.48.

Then The price of the stock is $27.36.

So, the decrease in amount= 35.48 - 27.36 = 8.12

Then, percent decrease

= 8.12/ 35.48 x 100

= 23.13%

Hence, the percent decrease is 23.13%.

Answer:

Step-by-step explanation:

radius of the circle=12 cm / 2=6 cm

Area of the square=side²=(12 cm)²=144 cm²

Area of the circle=πr²=(3.142)(6 cm)²≈(3.142)*36 cm²≈113.112 cm²

Area of the four  sides between the square and the circle=

=Area of the square - area of the circle=144 cm²-113.112 cm²=30.888 cm²

shaded area =30.888 cm²/4=7.722 cm²

Answer:

b

Step-by-step explanation:

The correct answer for the given problem above would be option B.

⇒ Fran must work 17 hours per week to meet her goal.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, According to the given details,

Fran works 15 hours per week for $225 which makes it $15 per hour.

Hence, If she adds another 2 hours per week to make it 17 hours,

Then, she will earn $255 dollars per week.

Now, since she is saving $40 dollars plus the two hours which is $30, a total of $70 per week of savings, multiplied by 20 weeks, then, she will be able to get $1,400.

Hence, The correct answer for the given problem above would be option B.

Answer:

The area of trapezoid is 39.6cm²

Step-by-step explanation:

Given that the formula of area of trapezoid is A = 1/2×(a+b)×h where a and b is the length and h is the height. So you have to substitute the values into the formula :

[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]

[tex]let \: a \: = 8.9 \\ let \: b \: = 5.5 \\ let \: h \: = 5.5[/tex]

[tex]area = \frac{1}{2} \times (8.9 + 5.5) \times 5.5[/tex]

[tex]area = \frac{1}{2} \times 14.4 \times 5.5[/tex]

[tex]area = \frac{1}{2} \times 79.2[/tex]

[tex]area = 39.6 {cm}^{2} [/tex]

 Answer: The area is 39.6

Step-by-step explanation:

First multiply 5.5×5.5= 30.25

Then subtract 8.9 - 5.5=3.4

Then multiply 5.5 x 3.4=18.7

Divide 18.7/2=9.35

Add 30.25 + 9.35 =39.6

Answer:

15/20 and 18/20

Step-by-step explanation:

Least common denomintor of 3/4 and 9/10 = least common multiple of 4 and 10

multiples of 4: 4, 8, 12, 16, 20

multiples of 10: 10, 20

Least common denominator = 20

Rewrite fractions: 15/20 and 18/20

3/4 and 9/10 using the least common denominator is 15/20 and 18/20.

LCM of two or more than two given numbers is the smallest common multiple that is divisible by two or more than two given numbers.

Given, are two fractions 3/4 and 9/10 we know the LCM of 4 and 10 is 20.

∴ (3×5)/(4×5) and (9×2)/(10×2).     (we have to multiply same constant to the  

                                                         fraction to retain it's original value).

So,  3/4 and 9/10 using the least common denominator is 15/20 and 18/20.
