Answer:

72 animals

Step-by-step explanation:

Let d = dogs

d+d25% = cats

Changing to decimal form

d+.25d= cats

d(1.25) =cats

There are 40 cats

d(1.25) =40

Divide each side by 1.25

1.25d/1.25 = 40/1.25

d =32

There are 32 dogs and 40 cats

The total number of animals

32+40 = 72

Determine the principal value of the function: Arc sin(square root of 3/2)

Drupady [299]

Answer:

π/3

Step-by-step explanation:

We have to find the principal value of $\text{arc sin}(\frac{\sqrt{3}}{2} )$

arc sin means sin inverse. The sin inverse is a one to one function with its range between $-\frac{\pi}{2} \textrm{ to } \frac{\pi}{2}$

The principal value of the arc sin will lie within the above given range.

value of sin (60) or sin( $\frac{\pi}{3}$ ) is $\frac{\sqrt{3}}{2}$ .

$\frac{\pi}{3}$ lies between $-\frac{\pi}{2}\textrm{ and } \frac{\pi}{2}$

So, from here we can say that the Principal Value of Arc sin(square root of 3/2) is π/3

What is the graph of the inequality 3x+2y>-5

Doss [256]

Answer:

The graph with solution is shown below.

Step-by-step explanation:

We need to find the $x-intercept$ and $y-intercept$ for given equation.

For $x-intercept$ , substitute $y=0$

Considering inequality sign as equality and simplifying,

$3x+2y=-5\\3x+0=-5\\x=-\frac{5}{3}$ , point is $(-\frac{5}{3} ,0)$

Similarly,

For $y-intercept$ , substitute $x=0$

We get,

$3x+2y=-5\\0+2y=-5\\y=-5/2$ , point is $(0,-\frac{5}{2})$

We locate this two points on the graph now and join them.

The joining line will be dotted as the inequality has just 'greater than' symbol. The region above the dotted line is the solution to graph.

Find the area of an equilateral triangle with a side of 6 inches.

sweet-ann [11.9K]

Answer:

9 $\sqrt{3}$ in²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the length of a side )

Here s = 6, thus

A = $\frac{6^2\sqrt{3} }{4}$ = $\frac{36\sqrt{3} }{4}$ = 9 $\sqrt{3}$ in²

Can u solve this questions.i don't know what to do.

PilotLPTM [1.2K]

Answer:

8

Step-by-step explanation:

average is calculated as

average = $\frac{sum}{count}$

$\frac{sum}{2}$ = 13 ( multiply both sides by 2 )

sum of 2 eldest = 26

Then for the 4 children

average = $\frac{26+2+4}{4}$ = $\frac{32}{4}$ = 8
