For this case we have that the order of algebraic operations is determined by PEMDAS:

P: Perform any calculation inside the parentheses, making the most internal ones first.

E: Simplify any exponential expressions.

MD: Do all the multiplications and divisions, from left to right, as they appear.

AS: Do all the addition and subtraction, from left to right, as they appear.

Then, we have the following expression:

-4 + 12 ÷ (-3) ÷ 10 + 3 (-2) =

-4-4 ÷ 10 + 3 (-2) =

-4-0.4 + 3 (-2) =

-4-0.4-6 =

-4.4-6 =

-10.4

Answer:

-10.4

Answer:

Step-by-step explanation:

First we calculate (-3)÷10 = -0.3

Then 12÷(-0.3) = -40

After that -4 + (-40) = -44

3(-2) = -6

Finally -44 + (-6) = -50

Answer:

Horizontal distance between lifeguard and the person is 22 feet.

Step-by-step explanation:

Given: A lifeguard sees a person in distress.The eye level of the lifeguard is 15 feet above the ground. Angle of depression is 34°.

To find: Horizontal distance between lifeguard and the person.

Solution : If we draw a triangle then tan∅ = $\frac{height}{base}$

Here base is the horizontal distance.

Now we put the values in the formula.

tan 34° = $\frac{15}{base}$

Or Base = $\frac{15}{tan34}$

= $\frac{15}{0.675} = 22.22 feet$

So the answer is 22 feet.

Length and breadth of a rectangular field is 5 : 3. If the breadth of rectangle is 60m, find the length of the rectangle.

djverab [1.8K]

Answer:

Step-by-step explanation:

Given data

Ratio of length to breadth is 5 : 3

hence in fraction form it is 5/3

the breadth of rectangle is 60m

let the length be x

5/3= x/3

cross multiply we have

5*3= 3x

15= 3x

divide both sides by 3

x= 15/3

x= 5m

Hence the length is 5m

4(2x + 2) + 12 > 100

Komok [63]

Answer:

x > 10

Step-by-step explanation:

4(2x + 2) + 12 > 100

4(2x + 2) > 100 -12

4(2x + 2) > 88

2x + 2 > 22

2x> 22-2

2x > 20

x > 10
