Does anybody know the answer ASAP???

Step-by-step explanation:

sin30° = x/14

1/2 = x/14

1/2 × 14 = x

x = 7

cos30° = y/14

squareroot3/2 = y/14

0.866 = y/14

y = 0.866 × 14

y = 12.124

Answer:

122

Step-by-step explanation:

Use the formula P=2(l+W)

the length would be 65ft and the perimeter would be 374

The simplification of the expression (h² + 9·h - 1) × (-4·h + 3), involves the

multiplication of the terms. The error is therefore;

3. Calculating errors when distributing -1

The expansion of (h² + 9·h - 1) × (-4·h + 3), is given as follows;

(h² + 9·h - 1) × (-4·h + 3) = -4·h³ + 3·h² - 36·h² + 27·h + 4·h - 3

Which gives;

-4·h³ - 33·h² + 31·h - 3

The calculation is therefore;

The graph that represents the equation y = -1/2x -3 is B

A graph is a series of points, discrete or continuous, forming a curve or a straight line, each of which represents a value of a given function.

Graphs could be positive, or negative.

When the increase in y results to an increase, in x then the graph is said to be positive graph while and increase in y leads to a decrease in x is called negative graph.

From the equation, y = -x/2 -3

If x = 0, then the y-intercept is  -3 which is below the x -axis.

Also, if x = 2, y will be -4, if x = 4, y = -5

These shows that as x increases y- decrease, making it a negative graph which slopes from left to right passing through the y-axis at x = -3 which is graph B

In conclusion the graph that represents the given equation is B

Answer:

B) 243 km^3

Step-by-step explanation:

The formula for volume is Length x width x height, so we must find those values. By looking at the shape, the length is 9 km, width is 9 km, and height is 3 km, and after substituting these values in the equation, we get 9 km x 9 km x 3 km. When multiplied, it equals to 243 km^3, so the answer for the volume of the solid is B) 243 km^3.

Answer:

X = 1

Step-by-step explanation:

Subtract 3 from both sides:

-6x+3-3=4x-7-3

Simplify the equation above:

-6x=4x-10

Subtract 4x from both sides:

-6x-4x=4x-10-4x

Simplify the equation above:

-10x=-10

Divide both sides by 10:

-10x/10=-10/10

Answer:

y = 3/11(x) - 19/11

Answer:

2/15

Step-by-step explanation:

slow heart rate and blue eyes (2) over total (15)

2/15 doesn't simplify

Answer:

13/100 is my final answer

Step-by-step explanation:

First, in order to get blue eyes, you need to be part of 40% thats not much but not little either. Then in order to get A fast heart rate out of that, you need to be part of the 26% out of 40% and that leaves you with 13 to 14 %.

I say 13 to 14 because both the 13 and 26 % came from a decimal that went on forever but due to rounding it can be 27 gets fast heart rate with 13 percent gets slow heart rate and blue eyes or 14 gets it and 26 gets faster

Answer:

Step-by-step explanation:

Depending on the tools available to your 11y.o., it's a typical question for linear inequalities.

Where a,b,c are the # of 1,15,50 coins given by the buyer, and d,e,f the # of coins given back by the seller.

1×a + 15×b + 50×c > 1×d + 15×e + 50×f

a+b+c+1>=d+e+f

a+b+c >=2

Now, there are other clues in the text :

If the seller gives back money, then you didn't pay with 1's, otherwise, it means you overpay and you could have given fewer coins. So a=0.

Similarly, the seller cannot give you back a coin of 50, otherwise, you could have given fewer coins as the buyer. So f=0.

So that gives :

15×b + 50×c > 1×d + 15×e

b+c+1>=d+e

b+c >=2

From that point on, there is only a handful of scenarios to test.

Answer:

No

Step-by-step explanation:

No. Congruent triangles should also have corresponding congruent side lengths.

Jaden is incorrect. two triangles are not congruent if their interior angles are congruent.

The correct option is C.

Two triangles are said to be congruent if the three sides and the three angles of both the triangles are equal in any orientation.

Given, statement

two triangles are congruent if their interior angles are congruent.

Even when two triangles have all angles same,

they can still have sides of different lengths.

However, the ratio of lengths of corresponding sides will be same.

But in this case, they will be called 'similar' triangles, not congruent.

For example, in the image below, both triangles are equilateral and have all angles equal but they are not congruent.

Hence,  two triangles with congruent angles are not congruent, Jaden is incorrect.

First month's profit of the company = $2,400.

After the first month, the profit is modeled by the function

J(t) = 2.5t + 1,250, t is the number of months after the first month the shop opened.

Now, P(t) describes the total profit earned by the company.

So, P(t) = (Profit earned from first month) + (Profit earned from remaining 11 months of the year)

= 2400 + (2.5t + 1250)

= 2.5t + 3650

Hence, total profit earned for the year = 2.5t + 3650.

Using the given equation, it is found that it lands on the ground after 0.875 seconds.

It is given by:

[tex]h(t) = -16t^2 + vt + h[/tex]

In which:

In this problem, considering that the projectile jumps straight into the air with an initial vertical velocity of 14 ft/s, the parameters are v = 14 and h = 0, hence:

[tex]h(t) = -16t^2 + 14t[/tex]

It lands on the ground when h(t) = 0, hence:

[tex]-16t^2 + 14t = 0[/tex]

[tex]t(-16t + 14) = 0[/tex]

Then:

[tex]16t = 14[/tex]

[tex]t = \frac{14}{16}[/tex]

[tex]t = 0.875[/tex]
