Answer:

D is the answer

Step-by-step explanation:

A filled circle means "or equal to" in which this case the symbol is less than or equal to, making the dot filled. Since 2 is greater than x, the line would start on the two and continue farther down the line to show that anything 2 or greater is more than x.

Simplify the expression. Write your answer as a power.<br><br> (−5/7)^8⋅(−5/7)^9

dem82 [27]

Answer: $(-\frac{5}{7})^{17}$

Step-by-step explanation:

The expression can be simplified by applying the a properties of exponents, specifically the Product of powers, which states that:

$(b^a)(b^c)=b^{(a+c)$

Where b is the base and a and c are exponents.

Then simplify it by rewriting the base ( $-\frac{5}{7}$ ) and adding the exponents of the expression (8 and 9).

You will get the expression simplified and written as a power:

$(-\frac{5}{7})^8(-\frac{5}{7})^9=(-\frac{5}{7})^{(8+9)}=(-\frac{5}{7})^{17}$

Ms Happy has decided to start wearing a face mask, because it is now required of her to do so. The mask she has started wearing

Alchen [17]

Answer:

37.20 %

Step-by-step explanation:

Circumference = 2 × pi × r

30 = 2 × 3.14 × r

r = 4.7770700637

Area of her face = pi × r²

3.14 × 4.7770700637²

= 71.6560509556 in²

Area of the mask = 9 × 5 = 45 in²

Uncovered area

= 71.6560509556 - 45

= 26.6560509556 units²

% of uncovered area:

26.6560509556/71.6560509556 × 100

37.2%

Answer:

Step-by-step explanation:

tan45° = 10/x

=> 1 = 10/x

=> x = 10

=> y^2 = 10^2 + 10^2 = 200

=> y = 100*sqrt(2)

=> b
