Answer:

If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour

Step-by-step explanation:

Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).

1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.

Answer:

D

Step-by-step explanation:

Neither Alex nor Jo are correct, because surface area is a 2-dimensional quantity, so it would be given in just square units, not linear nor cubic.

Answer:

y = 3x + 9

Step-by-step explanation:

If the line is parallel, that means it will have the same slope. So, the line will also have a slope of 3.

Using y = mx + b, plug in the slope and given point, and solve for b:

y = mx + b

6 = 3(-1) + b

6 = -3 + b

9 = b

Plug in the slope and b into y = mx + b

y = 3x + 9

So, the equation of the parallel line is y = 3x + 9

Answer: $4603.82

Step-by-step explanation:

Given

The initial cost of a car is [tex]P=\$20,000[/tex]

The rate of depreciation is [tex]i=12.5\%[/tex]

Depreciated value after n years is given by

[tex]\Rightarrow P(1-\frac{i}{100})^n\quad \text{where n=no. of years}[/tex]

Value after 11 years

[tex]\Rightarrow 20,000(1-\frac{12.5}{100})^{11}\\\\\Rightarrow 20000(0.875)^{11}=\$4603.82[/tex]

Answer:

2³ * 2² = 2³⁺² = 3⁵

2³ * 2² = 2³⁺² = 3⁵

[(2³)² = 2³ˣ² = 3⁶]

Answer:

The calculation for ROC is simple in that it takes the current value of a stock or index and divides it by the value from an earlier period. Subtract one and multiply the resulting number by 100 to give it a percentage representation.

Answer: 8 1/4 miles

Step-by-step explanation:

I think your question isn't well written and should be:

Nathan jogged 2 1/4 miles on Monday. On Wednesday, he jogged 3 1/3 miles and on Friday, he jogged 2 2/3 miles. How far did Nathan jog altogether?

This will be:

= 2 1/4 + 3 1/3 + 2 2/3

= 2 3/12 + 3 4/12 + 2 8/12

= 7 15/12

= 7 + 1 3/12

= 8 3/12

= 8 1/4 miles

Answer:

2 x 2 x 2 x 3 x 7 x 7 x 7

Answer:

B. 180

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

There are 2 ways you can do this. I'll show you one!

1. Find the Slope

      a. use the slope formla: (y1-y2)/(x1-x2)

               (4-1)/(-2-1)= 3/-3= -1

      This eliminates both B and D, as their slopes are -3

2. Now analyze the last 2 equations

        a. A goes through the ordered pair (-1, 1)

        b. C goes through the ordered pair (1, 1)

        The line we want goes through (-1, 1), so  A is the correct answer!

[tex]y-1=-3(x+1)[/tex] equation represents the line.

The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.

Given points

[tex](x_{1} ,y_{1} )[/tex] = (-1, 1)

[tex](x_{2} ,y_{2} )[/tex] = (-2, 4)

Using point slope form

We know that the equation of line passing through points [tex](x_{1} ,y_{1} )[/tex] and  [tex](x_{2} ,y_{2} )[/tex] is

[tex]y-y_{1} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }( x-x_{1})[/tex]

Therefore equation of line passing through points (-1, 1) and  (-2, 4) is

[tex]y-1=\frac{4-1}{-2+1}(x-(-1))[/tex]

[tex]y-1=\frac{3}{-1} (x+1)[/tex]

[tex]y-1=-3(x+1)[/tex]

Option B is correct.

Answer:

a) 12xy

b) 30pqr

Step-by-step explanation:

multiply the numbers and since x and y are not common terms then keep them as xy multiplied with 12

same goes with b)

Answer:

a would be 12xy

b would be 30pqr

Step-by-step explanation:

Again, don't really know how to explain, just multiply the numbers and add on the letters

Answer:

sin (3 x) - cos (x)=

= sin (2x + x) - cos (x)=

= sin 2x * cos x + cos 2 x * sin x - cos x = ( using additional formulas )

= 2 sin x cos² x + ( cos² x - sin² x ) sin x - cos x =

= 2 sin x cos² x + ( 1 - sin² x - sin² x ) sin x - cos x =

= 2 sin x cos² x + ( 1 - 2 sin² x ) sin x - cos x =

= 2 sin x cos² x + sin x  - 2 sin³ x - cos x
