If the question is to find the value of u and v, use sin-cos-tan ratio to solve it

Find the value of v
v/12 = tan 45°
v/12 = 1
v = 12
The value of v is 12

Find the value of u
sin 45° = v/u
u = v/sin 45°
u = 12/(√2/2)
u = 24/√2
rationalize
u = 24/√2 × √2/√2
u = 12√2
The value of u is 12√2

24 x 12 1/2 x 12 3/4 what is the volume of the fish tank
hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

To find the volume of the fish tank multiply out the dimensions.

We were given the dimensions as:

24 \times 12 \frac{1}{2}  \times 12 \frac{3}{4}

Change the numbers to improper fractions

24 \times  \frac{25}{2}  \times \frac{51}{4}

We cancel out to get

3 \times 25 \times 51

3825

What is the equation of the following graph?
ser-zykov [4K]

Answer:

y=0.5x + 5

Step-by-step explanation:

The points are (0,5) and (-10,0)

to find the slope do

0-5/-10-0 = 5/10 = 1/2 = 0.5

next plug one of the points into point slope formula

y-y1=m(x-x1)

lets use the point (-10,0)

y1=0

x1= -10

m= 0.5

y-0=0.5(x- -10)

y = 0.5(x+10)

distribute the 0.5

y=0.5x+5

A city’s population is increasing at a rate of 5% each year. Which type of model describes this situation?
Basile [38]

Answer:

Exponential

Step-by-step explanation:

Ir's exponential because linear would mean it is increasing by a specific number every year, in which this case does not. Quadratic would mean a vertex form would need to be used, and with the information given , that could not happen.

Whats the product of 2/3 × 36
Amanda [17]

Answer:

24 :)

Step-by-step explanation:

2 / 3  x  36 = ?

First of all, note that 36 is the same as 36/1 since 36 divided by 1 is 36. Therefore, start by setting up the problem like this:

36 / 1  x  2 / 3

Multiply the numerators together (36 x 2 = 72) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:

72 / 3

The greatest common factor of 72 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:

24 / 1

Convert the improper fraction above to a whole number to get the answer:

24

Hope this helps :)
