Solve the equation using addition or subtraction.

Mathematics
2 answers:
zimovet [89]3 years ago
6 0

Answer:

1. Solve the equation using addition or subtraction.

4=q+13

Taking like terms on one side, we get

4-13=q

=> -9=q

or q=-9    (option C)

2. Solve the equation using addition or subtraction.  

5.5= -2+d

Taking like terms on one side, we get

5.5+2=d

So, d=7.5    (option B)

3. Solve the equation using multiplication or division

-7y=28

Dividing both sides by 7, we get

-y=4

or y=-4    (option A)

4. Solve the equation using multiplication or division

-13=\frac{m}{-5}

Cross multiplying -13 and -5 to get the value of m

m=(-13)(-5)

m= 65      (option C)

The sears tower in chicago is 1450 feet high. A model of the tower is 24 inches tall. What is the ratio of the height of the mod
Dominik [7]

Answer:

\frac{1}{725}

The sear tower is 725 times higher than the sears tower model

Step-by-step explanation:

we know that

The ratio of the height of the model to the height of the actual sears tower is equal to the scale factor

Let

z------> the scale factor

x-------> the height of the model

y-------> the height of the actual

so

z=\frac{x}{y}

we have

x=24\ in

y=1,450\ ft

substitute

z=\frac{24}{1,450}\frac{in}{ft}

simplify

z=\frac{12}{725}\frac{in}{ft}

Remember that

1\ ft=12\ in

so

\frac{12}{725}\frac{in}{ft}=\frac{1}{725}\frac{ft}{ft}

How do you find the parameterization of a helix?
Marina CMI [18]

Answer:

\left\{\begin{array}{l}x=r\cos t\\ \\ y=r\sin t\\ \\z=at\end{array}\right.

Step-by-step explanation:

A <u>helix</u> is a curve for which the tangent makes a constant angle with a fixed line. The shortest path between two points on a cylinder (one not directly above the other) is a fractional turn of a helix, as can be seen by cutting the cylinder along one of its sides, flattening it out, and noting that a straight line connecting the points becomes helical upon re-wrapping (see attached diagram for helix).

The parametrization for the helix is

\left\{\begin{array}{l}x=r\cos t\\ \\ y=r\sin t\\ \\z=at\end{array}\right.,

where r is the radius of the helix, a is the constant, and t\in [0,2\pi ) is the parameter
