Answer 1

Answer:

468.5 in

(??? gonna be honest I'm not sure its right but gave it a shot so apologies if I gave u a wrong answer)

Step-by-step explanation:

(this is how I did it, like I said, not sure its right)

Dotted line:

we need to find the length of the dotted line in order to be able to calculate the area of the rectangle

radius = 8 in

diameter (dotted line)

= 8 x 2

= 16 in

(radius is half the diameter so now you know the length of the dotted line is 16 in - this answer is for the rectangle)

Area of the rectangle

A = L x W

using the 16 we found to calculate the area of the rectangle

A = 23 x 16

A = 368 in

Area of semi-circle:

Now to calculate the area of the semi-circle

A = π r² ÷ 2

A = π 8² ÷ 2

= 100.48

Adding the area of the rectangle and semi-circle together:

= 100.48 + 368

= 468.48

1dp = 468.5

tried to explain it as well as possible

sorry if its wrong

Hunter bought a cell phone for $159 and 6% sale tax was added at the register. Hunter gave the cashier nine $20 bills, how much change should he receive?

Answers

Answer:

Step-by-step explanation:

So in order to solve this you would multiply 159 by 6% and get 9.54 so therefore you add the 9.54 to 159 and get 168.24 Then you add together all the bills which is 180 and subtract 180- 168.24 which equals 11.76 so the answer to your question is that Hunter shall received $11.76 in change.

Hey! The answer would be $11.46

149 times 0.06 = 9.54
20-9.54 = 11.46

Lola ran 6.79 miles to prepare for her track meet today. If she runs this distance every day this week, how many miles will Lola run? (Remember, there are 7 days in one week).

Answers

Answer:

47.53 miles

Step-by-step explanation:

6.79×7= 47.53

Answer:

47.53 miles total for the week.

Step-by-step explanation:

so if she ran 6.79 for each 7 days that would be:

6.79 * 7 = 47.53

6.79 + 6.79 + 6.79 + 6.79 + 6.79 + 6.79 + 6.79 = 47.53

hope this helps!!

Sophia has a shelf that is 51 over 2 inches wide. How many notebooks can Sophia arrange on the shelf if each notebook is 3 over 2 inches thick?

38, because the number of notebooks is 51 over 2 ⋅ 3 over 2
153, because the number of notebooks is 51 over 2 ÷ 3 over 2
102, because the number of notebooks is 51 over 2 ⋅ 3 over 2
17, because the number of notebooks is 51 over 2 ÷ 3 over 2

Answers

That would be 17.
Why?
The number of notebooks is 51/2 divided by 3/2.
(51/2)/ (3/2)= 51/2 * 2/3 = 102/6 =1717

The answer to this is 17

Rewrite the expression in the form 5^n
(5^3)^2=?

Answers

This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.

The answer is 5^6 because if we have an exponent to the power of exponent we have to multiply the powers..

A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50° angle
of elevation. His eyes are 5 feet above the ground. Using cos 50° 0.64, what is the height of the tree
to the nearest foot?

36 feet
29 feet
24 feet
31 feet

Answers

Answer:

[tex] \tan(50) =opp(x) \div adh(20) \\ \tan50 \times 20 = opp(h) \\ = 23.8 [/tex]

therefore the answer is 24

The height of the tree is approximately 26 feet.

What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Let's denote the height of the tree with 'h'.

Then we can use the trigonometric ratio for cosine as follows:

cos(50°) = adjacent/hypotenuse

cos(50°) = 20/h + 5 (the adjacent side is the distance from the student's eyes to the tree, which is 20 feet, and the hypotenuse is the height of the tree plus the height of the student's eyes, which is h + 5 feet)

Now we can solve for 'h':

0.64 = 20/(h + 5)

0.64(h + 5) = 20

0.64h + 3.2 = 20

0.64h = 16.8

h = 26.25

So the height of the tree is approximately 26 feet (rounded to the nearest foot), which means the closest answer choice is 29 feet.

Therefore,

The height of the tree is approximately 26 feet.

1. Is the graph proportional?

2. How many feet can a sloth travel in 20 minutes?

Answers

Answer:

1. Yes

2. 60

Step-by-step explanation:

The graph is proportional because it passes an origin point.

The equation of the graph is

[tex]y = 3x \: \: (x \geqslant 0) \: \: (y \geqslant 0)[/tex]

We can find the distance when travelling in 20 minutes by substituting x = 20 in the equation.

[tex]y = 3(20) \\ y = 60[/tex]

Therefore the distance (ft) is 60.
