Find the unknown measures of the indicated angles.

Sever21 [200]

The angles of a triangle always equal to 180 degrees.

Knowing this, you can solve this by this equation

Angle A + Angle B + Angle C = 180

43 + 85 + Angle C = 180

Angle C = 180 - 43 - 85
Angle C = 52

what is the value of the expression? 4(6/10−1/5)+0.4 enter your answer, in simplest form, in the box.

MA_775_DIABLO [31]

Answer: 2.0

Step-by-step explanation:

The given expression : $4(\dfrac{6}{10}-\dfrac{1}{5})+0.4$

To solve the given expression , we need to follow BODMAS (Bracket→ Of Divide→ Multiplication →Add →Subtract).

According to BODMAS , first we simplified the expression present inside the brackets .

$4(\dfrac{6-2(1)}{10})+0.4$ [10= LCM[10,5]]

$=4(\dfrac{6-2}{10})+0.4$

$=4(\dfrac{4}{10})+0.4$

$=(\dfrac{4\times4}{10})+0.4$ [Multiply]

$=(\dfrac{16}{10})+0.4$ [Simplify]

$=1.6+0.4=2.0$ [Add]

Hence, the value of the expression in the simplified form = 2.0

If 25% of 150 is equal to 700 percent of n, then what number is n equal to?

Mrrafil [7]

Step-by-step explanation:

"Of" means multiplication, and percent means out of 100.

25/100 × 150 = 700/100 × n

75/2 = 7n

n = 75/14

n ≈ 5.357
