Answer:

Part b.

Step-by-step explanation:

Ok, so I think what you can do for part b. is pretty simple. You know that $820 is for 4 weeks of work. 820/4 = 205. So he gets $205 per week. If 820 = 100%, then 205*3 = 75%. So the answer would be he will recieve 75% of his usual pay, and that will be $615.

Answer:

29

Step-by-step explanation:

20^2 times 3.14= 1256

21^2 times 3.14= 1384.74

the sum of those two is 2640.74

the square root of that is 29

The radius of the circle is 29 cm.

We have the circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm.

We have to find the radius of the circle.

Let the radius of the circle be x.

We know that the area of the circle is [tex]\pi r^{2}[/tex]. Then -

[tex]\pi x^{2} =\pi r^{2} +\pi R^{2} \\x=\sqrt{r^{2} + R^{2}} \\[/tex]

Now, in the question given to us -

r = 20cm  and R = 21cm  and 'x' denotes the radius of the circle we have to find.

Substituting the values in the above formula, we get -

x = [tex]\sqrt{400+441}[/tex]

x =29 cm

Hence, the radius of the circle is 29 cm.

Answer:

(-2,3)

Step-by-step explanation:

The robot does not meet both of Fernando's expectations.

A represents the number of minutes the robot filters air.

W represents the number of minutes the robot filters water.

Inequality is a statement stating two expressions are not equal.

Expectation 1:

21A + 14W > 512

Given A=15 minutes

W=5 minutes

So, 21A + 14W =21*15 +14*5 =370

370<512

So, the robot does not meet Fernando's first expectation.

Expectation 2:

0.36 A + 0.6W < 9

A=15 minutes

W=5 minutes

So, 0.36 A + 0.6W =0.36*15+0.6*5 = 8.4

8.4<9

So, the robot meets Fernando's second expectation.

Hence, the robot does not meet both of Fernando's expectations.

Answer:

p=19

Step-by-step explanation:

since the instructions say that ([tex]x^{13}[/tex])([tex]x^{6}[/tex]) is equivalent to [tex]x^{p}[/tex], we can make the equation:

([tex]x^{13}[/tex])([tex]x^{6}[/tex])=[tex]x^{p}[/tex]

now, apply the laws of exponents; [tex]a^{m} * a^{n} =a^{m+n}[/tex]

in that case, since we're multiplying x to the 13th power by x to the 6th, the result is [tex]x^{13+6}[/tex], which is [tex]x^{19}[/tex]

the equation now:

[tex]x^{19}[/tex]=[tex]x^{p}[/tex]

since the exponents are at the same base, we can solve the equation

19=p

so p is 19

Answer is 3

Step-by-step explanation:

first what you do is you rearrange the numbers so the eqaution is -2x+4=-2

SO what you do is (4) - 4 to cancel it out then you do the same thing on the other side so (-2)-4=-6 so the equation now is -2x=-6 then you divide -2 to cancel it out and you do the same thing -6 divide by -2 is 3 so the answer is 3

Answer:

see explanation

Step-by-step explanation:

∠ AOB = 360° - 264° = 96°

The altitude OM bisects ∠ AOB and the base AB

(a)

∠ MOB = 0.5 × 96° = 48°

Using the cosine ratio in right triangle MOB

cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{OB}[/tex] = [tex]\frac{18}{r}[/tex] ( OB is the radius r of the circle )

Multiply both sides by r

r × cos48° = 18 ( divide both sides by cos48° )

r = [tex]\frac{18}{cos48}[/tex] ≈ 27 cm ( to the nearest cm )

(b)

Using the tangent ratio in the right triangle MOB

tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{MB}{OM}[/tex] = [tex]\frac{MB}{18}[/tex] ( multiply both sides by 18 )

18 × tan48° = MB then

AB = 2 × MB = 2 × 18 × tan48° = 36 × tan48° ≈ 40 cm ( to nearest cm )

Step-by-step explanation:

it says two less which means that you would be subtracting 2 from 3 and a number wich is 3x - 2

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The expression that represents the statement

“two less than the product of three and a number” is

3M - 2.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3x - 4 + 5 is an expression.

3x = 5 + 4 is an expression.

We have,

“two less than the product of three and a number”

Let the number be = M

This can be written as,

3 x M - 2

Answer:

8 units²

Step-by-step explanation:

The area (A) of the shaded part (right triangle ) is calculated as

A = [tex]\frac{1}{2}[/tex] × area of rectangle

   = 0,5 × 4 × 4 = 0.5 × 16 = 8 units²

Answer:

8 units ^2 are shaded

Step-by-step explanation:

The total area of the square is 4 * 4 = 16

1/2 of the square is shaded so

1/2 * 16 = 8

8 units ^2 are shaded

Answer:

It would take 12.1 years.

Step-by-step explanation:

We are given with $3000 invested in bank pays 6.75% interest compounded semi annually to the nearest 10th. We are asked to find the number of years the bank reaches $6700.

Let's use the compound interest formula.

[tex]A= P(1+\frac{r}{n}) ^{nt}[/tex]

We know A=6700

P=3000

r =0.0675

n=2(because compounded semiannually)

t =?( we need to find it)

Plug in the known values into the formula.

[tex]6700=3000(1+\frac{0.0675}{2}) ^{2*t}[/tex]

Simplify and solve for 't'

Divide both sides by 3000

[tex]2.23333= (1.03375)^{2t}[/tex]

Take log on both sides

[tex]log(2.23333) = 2t log(1.03375)[/tex]

Divide both sides by log(1.03375)

24.2067=2t

Divide both sides by 2.

t=12.10...

To round to nearest 10th, we get t=12.1 years.
