Answer:

157 cm^2

Step-by-step explanation:

area = pi r^2 you need half so 1/2 (3.14) (10^2)= 1/2 (3.14)(100), 1/2 (314)=157

Answer:

133°

Step-by-step explanation:

angles on a straight line = 180°

180 - 144 = 36°

angles in a triangle = 180°

36 + 31 = 67

180 - 67 = 113

answer = 113°

Answer: 2.10

Step-by-step explanation: 2.10 * 4 + 6

Answer:

11 feet

Step-by-step explanation:

Length of diagonal of square of side a = √2a

Here value of a = 8 feet

Therefore length of diagonal d = √2×8 = 1.414×8 =    11.312 feet

So after rounding to the nearest tenth the length of diagonal becomes 11 feet

Answer:

the exact value is x =1/2 or x=0.5

your welcome!

The exact value is x = 1/2.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given an expression as;

[tex]27^{-1/3} = \frac{9^{1/4} }{3^{r + 1}}[/tex]

Now we can see that

27 = 3³

9 = 3²

Then the power are 3(-1/3) = -1

3(1/4) = 3/4

So we have;

[tex]3^{-1} = \frac{3^{2/4} }{3^{r + 1}}\\\\3^{-1} =3^{1/2 -r - 1} \\\\3^{-1} =3^{1 -2r - 2 /2}\\\\3^{-1} =3^{-2r - 1/2}[/tex]

So,

-2 = -2r - 1

-2r = -1

r = 1/2

Answer:

Jamal contribution = Total fee - scholarship & grant - study program earnings - family contribution

Step-by-step explanation:

Let total fee = x

Jamal contribution = x - 8200 - 1900 - 21000

= x - 31100

Her fee above & beyond 31100 will have to be arranged by Jamal's own contribution

Answer:

Step-by-step explanation:

50a³b = 2⋅5²a³b

8ab = 2³ab

GCF = 2ab

50a³b - 8ab = 2ab(5²a² - 2²)

5²a² - 2² = (5a - 2)(5a + 2)

Answer:

$10

Step-by-step explanation:

Her hourly rate is 10 because if she earned $5 for half and our or 30 minutes that means to get to 1 hour multiply by 3 so you get. $10 per hour

Answer:

$10 per hour.

Step-by-step explanation:

$5 = 1/2 an hour | 30 minutes

So if you were to multiply $5 by 2 you'd get $10 which would make 1 whole hour.

Answer:

Substitute the 80°F where the F is in the equation. then just put the whole equation into your calculator. I got approximately 26.7.

Given:

The expression is:

[tex]\dfrac{(-24)^5}{(-24)}[/tex]

To find:

The value of the given expression into a single power.

Solution:

Given that,

[tex]\dfrac{(-24)^5}{(-24)}[/tex]

It can be rewritten as:

[tex]\dfrac{(-24)^5}{(-24)}=(-24)^{5-1}[/tex]       [tex][\because \dfrac{a^m}{a^n}=a^{m-n}][/tex]

[tex]\dfrac{(-24)^5}{(-24)}=(-24)^{4}[/tex]

Therefore, the required expression is single power is [tex](-24)^{4}[/tex].

The area of triangle IJK is 999.8 square centimeters

The given parameters are:

[tex]\angle I = 120^o[/tex]

[tex]\angle J = 59^o[/tex]

[tex]i = 340cm[/tex]

Start by calculating the length of side j using the following sine ratio

[tex]\frac{i}{\sin(I)} = \frac{j}{\sin(J)}[/tex]

Make j the subject of the formula

[tex]j = \sin(J) \times \frac{i}{\sin(I)}[/tex]

Substitute known values

[tex]j = \sin(59) \times \frac{340}{\sin(120)}[/tex]

Evaluate the expression

[tex]j = 337[/tex]

Next, calculate angle K using the following sum of angles formula

[tex]\angle I + \angle J + \angle K =180[/tex]

Substitute known values

[tex]120 + 59 + \angle K =180[/tex]

[tex]179 + \angle K =180[/tex]

Subtract 179 from both sides

[tex]\angle K =1[/tex]

The area of the triangle is:

[tex]Area = \frac{1}{2} ij \times \sin(K)[/tex]

So, we have:

[tex]Area = \frac{1}{2} \times 340 \times 337 \times \sin(1)[/tex]

Evaluate

[tex]Area = 999.8[/tex]

Hence, the area of triangle IJK is 999.8 square centimeters
