Here are the areas of the 3 separate shapes:

1. 27.5 m^2

2. 25.5 m^2

3. 27.5 m^2

As you can see, the 1st and 3rd shapes share the same total area, so those are the shapes you should select.

[tex]-2x^2-8x+12[/tex]

Step-by-step explanation:

[tex]f-g=(3x^2-2x+4)-(5x^2+6x-8)=3x^2-2x+4-5x^2-6x+8=\\ =-2x^2-8x+12[/tex]

Let the radius of the base be r units

Then the height will be 3r units

Volume of cylinder = pi r^2 h

24=pi r^2 × 3r

Pir^3 = 24/3

Pi r ^3 =8

r^3 = 8/pi

R = 2 / pi^1/3

Height = 6/pi^1/3

Answer:

yes 1/16

Step-by-step explanation:

To solve the equation −13+2z=−56, we isolate z by first adding 13 to both sides, giving 2z=−43, and then dividing both sides by 2, resulting in z=−21.5.

The student is asking for the solution to the linear equation −13 + 2z = −56. To solve for z, we need to perform two steps. First, add 13 to both sides of the equation to isolate the term with z on one side. This gives us 2z = −43. Next, we divide both sides by 2 to solve for z, which results in z = −21.5.

Final answer:

To find the length of the rope anchoring the boat to the shore, use the tangent function with the angle of depression and the height of the boat above the water.

Explanation:

To find the length of the rope anchoring the boat to the shore, we can use trigonometry. The angle of depression from the boat to the water is 40° and the height of the boat above the water is 25.17 feet. We can use the tangent function to find the length of the rope. tan(40°) = opposite/adjacent. The height of the boat above the water is the opposite side and the length of the rope is the adjacent side. So, we have:

tan(40°) = 25.17/adjacent

Solving for the adjacent side, we get:

adjacent = 25.17 / tan(40°)

Using a calculator, we can evaluate this expression to find that the length of the rope is approximately 33.95 feet.

The answer is: d) in step 5 he should have multipled both sides by 1/3.

Answer:

D

Step-by-step explanation:

Hey there!!  

Given equation :

... 4 ( 3q - 2 ) = 16q

... 12q - 8 = 16q

Subtract by 12q on both sides

... -8 = 4q

Divide by 4 on both sides

... -8 / 4 = q

... q = -2

Given equation :

4 ( 3q - 2 ) = 16q

Substitute the value of -2 in place of q

... 4 ( -6 -2 ) = 16 × -2

... 4 ( -8 ) = -32

... -32 = -32

∴ Hence proved

The number name for 43,080,700 is Forty-three million, eighty thousand and seven hundred.

It is required to find the number name.

Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.

Given:

The number name for 43,080,700 is

Forty-three million, eighty thousand and seven hundred.

Therefore, the number name for 43,080,700 is Forty-three million, eighty thousand and seven hundred.

Answer:

One number is 17 and the other is 85.

Step-by-step explanation:

Let the numbers be m and n.  Let m = (1/5)n.  Note that m+n = 18.

Substituting (1/5)n for m in the 2nd equation, we get (1/5)n + (5/5)n = 18.  Multiplying all three terms by 5 to remove fractions, we get n + 5 = 90, so that n = 85.  m is (1/5) of 85, or m = 17.

Final answer:

The two numbers in question are 15 and 3. To find them, establish a variable for the larger number, set up an equation based on the given ratio and sum, solve for the variable, and divide by five to get the smaller number.

Explanation:

The student wishes to find two numbers where one number is one-fifth of the other and their sum is 18. Let's denote the larger number as x and the smaller number as one-fifth of x, or x/5. The equation representing their sum is x + (x/5) = 18. To solve for x, we first find a common denominator, which is 5, and rewrite the equation as 5x/5 + x/5 = 18. Combining like terms gives us 6x/5 = 18. Multiplying both sides by 5/6, we get x = (18 × 5) / 6. Simplifying this gives x = 15. We then calculate x/5 to find the smaller number, yielding 3. Therefore, the larger number is 15 and the smaller number is 3.

We are given: a mountain descends (getting down vertically) = 100 meter.

For getting down we would take it by a negative number so it would be -100 meter.

And every horizontal distance  = 1,000 meter.

We know formula for slope is = Change in vertical distance/ Change in Horizontal distance.

Plugging values in formula of slope above, we get

Slope = -100/1000 = -1/10 or -0.1.

Therefore, we could say the slope of a mountain is [tex]-\frac{1}{10}\ or \ -0.1.[/tex]

Do 450 divided by 18, which equals 25

(7a+2)(7a-2)

= (7a)^2 - (2)^2

= 49a^2 - 4

Answer:

sin (θ) = 0,58

Step-by-step explanation:

The formula for sin (θ) is:

sin (θ) = (opposite side)/hypotenuse

The opposite side to the θ angle is the one that measures 5 inches, but we don’t know the measure of the hypotenuse. The Pythagoras theorem gives us the following formula:

side 1²+ side 2²= hypotenuse²

Then,

5²+7²=74

√74= 8,60 inches; this is the measure for the hypotenuse.

Replacing this value in the formula for sine:

sin (θ) = 5/8,60  = 0,58

the answer should be D

The answer shoud be D because the line are across from each other.

ANSWER

[tex]3.\bar4 =\frac{31}{9}[/tex]

EXPLANATION.

Let [tex]y=3.\bar4---(1)[/tex]

This is a recurring decimal. So we need to multiply by 10 to form a new equation that will cater for the recurring but when subtracted.

Multiply (1) by 10 to obtain,

[tex]10y=34.\bar4---(2)[/tex]

Equation (2) -equation (1) gives;

[tex]9y=31[/tex]

[tex]\Rightarrow y=\frac{31}{9}[/tex]

Hence the correct answer is A.

So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)
