Answers

Answer 1

Answer:

#4

Area of rectangle:

A = lw = 10*20 = 200 m²

Shaded area:

A = 2πr² = 2π(10/2)² = 157.079 m²

Probability:

P = 157.079/200 ≈ 0.785 or 78.5%#5

Area of bigger circle:

A = πr² = π(20)² = 1256.637 m²

Shaded area:

A = π(10² - 5²) = 235.619 m²

Probability:

P = 235.619/1256.637 ≈ 0.187 or 18.7%
Answer 2

Answer:

4

We know that

Area of rectangle = lb

Area = 10(20)

Area = 200 m²

Shaded region = πr²

=> 2 × 22/7 × (10/2)²

=> 2 × 22/7 × 10/4

=> 157 m²

Probability = 157/200 = 78.5%

5.

Area of the biggest circle = πr²

= 22/7 × (20)²

= 1256.6

Area of shaded region

π(10² - 5²)

π(100 - 25)

3.14(75)

235.6

Probability = 235.6/1256.6 = 18.7%

Figure B is a scaled copy of Figure A.
What is the scale factor from Figure A to figure B?

Answers

Answer:

1/3

Step-by-step explanation:

The left side of Figure A is 6 units long

The left side of Figure B is 2 units long

6 * what = 2

Divide each side by 6

what = 2/6

what = 1/3

The scale factor is 1/3

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Figure A has a base of [tex]6[/tex] units.

Figure B has a base of [tex]2[/tex] units.

So, 6 * [tex]x[/tex] (the scaled factor) = 2 which simplified is [tex]6x=2[/tex].

Now, we divide 6 on both sides giving us [tex]x = \frac{2}{6}[/tex] which can be further simplified into [tex]\frac{1}{3}[/tex]

An expression is shown below.
6ab^2 + 9a^2b
Which of the following shows an equivalent expression?

Answers

Answer:

C. 3ab ( 2b + 3a )

Step-by-step explanation:

substitution

Hi! I'm happy to help!

To first solve this, Let's see if we can simplify our expressions using the order of operations: our original expression cannot be simplified. The first expression cannot be simplified. The second expression we can multiply the outside by the parenthesis by the inside, same with the third and fourth.

(make sure everything outside of the parenthesis is being multiplied by each part inside of the parenthesis)

9a²b²

9a²b²

3ab(3b+2a)

ab(9b+6a)

b(9ab+6a²)

9ab²+6a²b

3ab(2b+3a)

ab(6b+9a)

b(6ab+9a²)

6ab²+9a²b

3a²b²(2b+3a)

a²b²(6b+9a)

b²(6a²b+9a³)

6a²b³+9a³b²

Now that we have all expressions fully simplified, let's compare to see which one matches.

Our first expression is nowhere close to what our original expression is, 1 is incorrect.

Our second expression is close, but it has the 9 and the 6 flipped, even if we rearrange the expression like this, 6a²b+9ab², it still doesn't match, so 2 is also incorrect.

Our third expression has the correct numbers, variables, placement, and exponents, so 3 is correct.

Our fourth expression has incorrect exponents, the expression made every variable multiplied by ab an extra time, so 4 is incorrect.

In summary, you should pick number 3, because it is equivalent.

A cell phone tower casts an 80-foot shadow. At the same time, a 6-foot fence
post casts a shadow of 4 feet. What is the height of the tower?

Answers

The height of the tower is 120 feet

How to determine the height of the tower?

The given parameters can be represented using the following ratio

Ratio = Height : Shadow

So, we have:

Tower : 80 ft = 6 ft : 4 ft

Express as fraction

Tower/80 = 6/4

Multiply both sides by 80

Tower = 120 feet

Hence, the height of the tower is 120 feet

Marley made three full pitchers of lemonade. Eachpitcher holds exactly five cups of liquid. How many ounces of lemonade did Marley make?

Answers

Answer:

120 fluid ounces

Step-by-step explanation:

1 cup = 8 fluid oz

Multiply 15 on both sides (since there is 3 pitchers and each is 5 cups, so 3 * 5 = 15 cups in total for all 3 pitchers) and we get 15 cups = 120 fluid oz.

So that's our answer

The midday temperature, in Celsius degrees (°C), on four successive days is 1.5, -2.6, – 3.4 and 0.5. Calculate the mean temperature.

thanks for anyone who helped <3 ​

Answers

Answer:

-1 C

Step-by-step explanation:

Mean = Average

To find the mean simply add all the values and then divide that by the number of given values

So first add the 4 values together

1.5 + -2.6 + -3.4 + .5 = -4

Then divide the sum by the number of values ( there are 4 values )

-4 / 4 = -1

The mean temperature is -1

When a new cellphone is put on the market, the demand each month can be described by the function C of t is equal to negative square root of the quantity t squared plus 4 times t minus 12 end quantity plus 3 where C (t) represents the demand of the cellphone (measured in millions of people) and the time, t, is measured in months. Which of the following solution(s) are valid for a positive demand?

Answers

A function is positive where it is above the x-axis

The valid solution for positive demand are; t = 3, and t = 2

The reason the above values are correct is as follows:

Known parameters:

The given function of the demand is; [tex]C(t) = \mathbf{ -\sqrt{t^2 + 4 \times t - 12} +3}[/tex]

Where;

C(t) = The demand of the cellphone (in millions of people)

t = The number of months

The condition positive demand is C(t) ≥ 0

Therefore;

[tex]-\sqrt{t^2 + 4 \times t - 12} +3 \geq 0[/tex]

[tex]-\sqrt{t^2 + 4 \times t - 12} \geq -3[/tex]

[tex]\sqrt{t^2 + 4 \times t - 12} \leq 3[/tex]

t² + 4·t - 12 ≤ 9

t² + 4·t - 12 - 9 ≤ 0

t² + 4·t - 21 ≤ 0

(t - 3) × (t + 7) ≤ 0

∴ t ≤ 3, or t ≥ -7

At t = 2 < 3, we have;

C(2) = -√(2² + 4×2 - 12) + 3 = 3

At t = 1 < 3, the function is; C(1) = -√(1² + 4×1 - 12) + 3 (Is undefined)

Therefore, the valid solution for positive demand are;

t = 3, and t = 2

Step-by-step explanation:

Plug in x = -3

5(-3) - 4[7+(2(-3)-4)]

We'll use order of operations (PEMDAS) from here on out.

Evaluate what is in the innermost parentheses first (2(-3) - 4: the parentheses inside of the brackets). We first multiply 2 * -3, then subtract -4.

2(-3) - 4 = -6 - 4 = -10

So the whole expression becomes

5(-3) - 4[7+ -10]

Now evaluate what is in brackets.

5(-3) - 4[-3]

Multiplication next, before addition.

-15 + 12

Finally, addition
