Answer:
Original Equation: s + 3 1/2 = 8 1/2
Subtract 3/12 from both sides: s + 3 1/2 - 3 1/2 = 8 1/2 - 3 1/2
Simplify: s = 5
So, A is the correct answer.

Marcos debe pintar 5/9 de la cubierta de un velero. Al acabar el día ha pintado 21/36 . ¿Ha conseguido cumplir su objetivo? ¿Ha pintado más? ¿Ha pintado menos?
Answers
Answer:
a) Have you managed to meet your goal?
Yes
b) Have you painted more? Have you painted less?
You have painted more.
Step-by-step explanation:
Marcos should paint 5/9 of the deck of a sailboat.
At the end of the day he painted 21/36.
Reducing this to the simplest form = 21/36
Dividing Numerator and Denominator by 3
= 7/12
Finding the difference between both fractions
= 7/12 - 5/9
The Lowest Common Denominator = 36
= 21 - 20/36
= 1/36
Therefore:
a) Have you managed to meet your goal?
Yes
b) Have you painted more? Have you painted less?
You have painted more.

Consider the relationship in special right triangles to determine the tangent ratio for a 45 degree angle. Give your answer, as necessary, to the nearest thousandth place (three decimal place values).
Answers
Answer:
1
Step-by-step explanation:
The tangent of a angle is opposite side/ adjacent side
In a rights triangle with a 45° angle we have a special 45-45-90 triangle.
The legs of the triangle are congruent and are the opposite and adjacent sides of the 45° angle. Therefore, the ratio of those two sides is 1.
Therefore, the tangent of 45° = 1

Can someone plzzz help ASAP
Answers
Answer:
x = 7 √3 km
Step-by-step explanation:
Here, we want to get the value of x
As we can see, we have a right angled triangle with hypotenuse 14 km
we can use the Pythagoras’ theorem to get the value of x
Mathematically, the square of the hypotenuse equals the sum of the squares of the two other sides
Thus,
14^2 = x^2 + 7^2
x^2 = 196-49
x^2 = 147
x = 7 √3 km

The division of fraction 9/14 by 15/2 in simplest form is 3/70 by dividing both the numerator and the denominator by the GCD
To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 15/2 is 2/15. Therefore, we can rewrite the division as multiplication:
(9/14) * (2/15)
Next, we can multiply the numerators together and the denominators together:
(9 * 2) / (14 * 15)
Simplifying further, we get:
18 / 210
To simplify the fraction, we can find the greatest common divisor (GCD) of the numerator and the denominator, which is 6 in this case. Dividing both the numerator and the denominator by the GCD, we get:
18 ÷ 6 / 210 ÷ 6
This simplifies to:
3 / 35
Therefore, the division of 9/14 by 15/2 in simplest form is 3/70.
In summary, to divide fractions, we multiply the first fraction by the reciprocal of the second fraction. Then, we simplify the resulting fraction by finding the GCD of the numerator and the denominator and dividing both by the GCD. Applying these steps to the given fractions, we obtain the simplified form of 3/70.

When salt and water are combined, they form a salt or saline solution. How much ml of water must be added to 150 mL of an 80% saline solution to produce a 30% saline solution?
Answers
Answer:
We must add 400 ml of water.
Step-by-step explanation:
We can use the following equation:
[tex]C_{i}V_{i}=C_{f}V_{f}[/tex]
Where:
C(i) is the initial concentration of the solution (80%)C(f) is the final concentration of the solution (30%)V(i) is the initial volume (150 ml)V(f) is the final volumeNow, we just need to solve the equation for V(f).
[tex]V_{f}=\frac{C_{i}V_{i}}{C_{f}}[/tex]
[tex]V_{f}=\frac{80*150}{30}[/tex]
[tex]V_{f}=400\: ml[/tex]
Therefore, we must add 400 ml of water.

Step 1: Define
-29 = 9 - 6k - 2k - 1
Step 2: Solve for k
Combine like terms: -29 = 8 - 8k[Subtraction Property of Equality] Subtract 8 on both sides: -37 = -8k[Division Property of Equality] Divide -8 on both sides: 37/8 = kRewrite/Rearrange: k = 37/8Step 3: Check
Plug in k into the original equation to verify it's a solution.
Substitute in k: -29 = 9 - 6(37/8) - 2(37/8) - 1Multiply: -29 = 9 - 111/4 - 37/4 - 1Subtract: -29 = -75/4 - 37/4 - 1Subtract: -29 = -28 - 1Subtract: -29 = -29Here we see that -29 does indeed equal -29.

Andre is making paper cranes to decorate for a party. He plans to make one large paper crane for a centerpiece and several smaller paper cranes to put around the table. It takes Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will only have 30 minutes to make the paper cranes once he gets home.
Andre wrote the inequality 3x + 10 ≤ 30 to plan his time. Describe what x, 3x, 10, and 30 represent in this inequality.
Solve Andre’s inequality and explain what the solution means.
Answers
Answer:
6 small cranes
Step-by-step explanation:
3x + 10 is less than or equal to 30
3 is the minutes for the small cranes
X is the amount of small cranes
10 is the minutes for the large crane
30 is the total time limit
first, subtract 10 from 30, which gives you 20 so
3x is less than or equal to 20.
to figure this out, divide 20 by 3, which gives you 6 with a remainder of two minutes.
Andre can make 6 small cranes.

Answers
question isn't clear but I believe you are asking for the area of triangle ABC given sides a, b, c
We use the example question:
Find the area (in square units) of the triangle described.
a = 49mm, b = 33mm, c = 18mm
Answer and explanation:
We apply Heron's formula to solve the area of a triangle given the sides of the triangle a, b, c
A= √s(s-a)(s-b)(s-c)
Where A = area of triangle in square units
s= semiperimeter(a+b+c/2) of a triangle
a, b, c= lengths of the sides of the triangle
Therefore area of triangle =√50(50-49)(50-33)(50-18)
= √27200

r = sq rt [v/(h x Pi)]
r = 1.69
Step-by-step explanation:
v=h x Pi x r^2
r^2 = v/(h x Pi)

r = sq rt [67.57 / (7.5 x 3.14)]
r = sq rt 2.8692
r = 1.69
