Expert Answer:

Since the numbers are in the ratio 3:4 then let the numbers be 3x and 4x.

Thus the H.C.F. of the two numbers = x.

But the H.C.F is given as 4.

So, x = 4.

So, the numbers are,I

3x = 3 x 4 =12

And

4x = 4 x 4 = 16

We know,

H.C.F x L.C.M = Product of the two numbers

4 x L.C.M = 12 x 16

L.C.M = 48

Thus, the L.C.M of 12 and 16 , 48

Answer:

x = 12

y = -2

Step-by-step explanation:

In a parallelogram, the sides opposite each other are equal.

Hence: PQ = SR and PS = QR

2x + 12 = 4x - 12

Rearrange to make x's on one side and the numbers on the other

4x - 2x = 12 + 12

2x = 24

x = 12

____________

y + 25 = 6y + 35

Rearrange to make y's on one side and the numbers on the other

6y - y = 25 - 35

5y = -10

y = -2

C. 114

Step-by-step explanation:

bikes have 2 wheels

skateboards have 4 wheels

incline skates have 8 wheels in total

7*2 = 14

9*4 = 36

8*8 = 64

if you add all of these up you get 114 wheels in total. 8*8 was from 24-7-9 = 8

Answer:

Step-by-step explanation:

Remark

By corresponding angles and vertical angles, these two angles are equal.

Equation

-1 + 14x = 12x + 17                      Subtract 12x   from both sides

Solution

-1 + 14x - 12x = 12x - 12x + 17

-1 + 2x = 17                                 Add 1 to both sides

-1+1 + 2x = 17 + 1

2x = 18                                       Divide by 2

2x/2 = 18/2

x = 9

The distance from the runner in 2nd place to the point directly below the helicopter is given as follows:

304.26 feet.

The three trigonometric ratios are defined as follows:

The parameters for this problem are given as follows:

Hence the distance is obtained applying the tangent function as follows:

tan(60º) = 527/x

x = 527 / tangent of 60 degrees

x = 304.26 feet.

Answer:

C= 27

G= 37

J=57

Z= 1

Step-by-step explanation:

These are the degrees because of the Triangle Sum Theorem which states that The sum of the measures of the angles in a triangle is 180°. So angle C for example is 27 because angle A is 53 and angle B is 100 add both of those and you get 153 so our equation would be 153+c=180, c being the angle, so then to solve this you do do 180-153 and that equals 27 so therefore, 153+27=180. This process applys to all the other angles as well ^w^

Answer:

15 ft

Step-by-step explanation:

At 15 feet below the surface, the scuba diver did his safety stop.

The surface is the common region between two different mediums. Here in the question surface is the common region between seawater and above seawater.

Let us denote the values of descending by negative sign and rising by positive sign and we sum up all the values together.

∴ [ - 80 + 25 + (-12) + 52 ] feet.

= (-80 + 25 - 12 + 52) feet.

= - 15 feet.

So, at 15 feet below the surface the scuba diver dis his safety stop.

Answer:

5 days

Step-by-step explanation:

To find out this question, we can subtract the amount she wants to get, 25, by the amount she has, 15:

25 - 15 = 10

So, Jomaya wants to save up $10, and because she saves $2 every day, we can divide:

10 / 2 = 5

So, it will take Jomaya 5 days to save $25

The given non-linear function will have three solutions.

A nonlinear system is a system in which the change of the output is not proportional to the change of the input.

Given is a graph of a nonlinear function, we need to find the number of the solution this function holds,

We know that the by studying the graph of any function we can deduce the number of solution,

We know that the number of times graph intersects each other is its solution,

Looking at the graph we can see that the graph is intersecting the graph three times,

Hence, the given non-linear function will have three solutions.

Factoring the given expression:

Answer:

−5x(3x+2)^2

Step-by-step explanation:

-45x^3-60x^2-20x

Factor out 5.

5(−9x^3-12x^2-4x)

Consider −9x^3-12x^2-4x. Factor out x.

x(−9x^2−12x−4)

Consider −9x^2−12x−4 Factor the expression by grouping. First, the expression needs to be rewritten as −9x^2+ax+bx−4. To find a and b, set up a system to be solved.

a+b=−12

ab=−9(−4)=36

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 36.

−1,−36

−2,−18

−3,−12

−4,−9

−6,−6

Calculate the sum for each pair.

−1−36=−37

−2−18=−20

−3−12=−15

−4−9=−13

−6−6=−12

The solution is the pair that gives sum −12.

a=−6

b=−6

Rewrite −9x^2−12x−4 as (−9x^2−6x)+(−6x−4).

(−9x^2−6x)+(−6x−4)

Factor out −3x in the first and −2 in the second group.

−3x(3x+2)−2(3x+2)
